Cosmos Press Solution for Backing Plate of Brake Pad Production

Abstract: This paper introduces an environmentally-friendly and efficient servo hydraulic press for production of backing plate of brake pads launched by Cosmos Presswhich widely used in the brake pad industry in past few years.

Keywords: automobile brake pad, production of steel backing, automatic production.

 

In whole automobile components industry, braking system is a key part of automobile. Without it, the driving safety of the automobile cannot be guaranteed.
The brake pad is one of the important components in the braking system. In addition to the quality of friction block, the quality of the brake pad is greatly affected by the flatness and the sheared edge quality of backing plate. Its flatness, sheared edge zone and size are directly related to the service effect of the backing plate.
The larger the burr and the more uneven the sheared edge and flatness, the higher the braking noise and the worse the braking effect. Therefore, the production process and the special equipment for backing plates are very important.

1. Difficulties in production process and special equipment for backing plate

Our investigations in Guangdong, Jiangsu, Zhejiang, Hebei and Shandong district reveal that the production of backing plate has the following features: the steel plate is relatively thick, generally 4-6mm, while the backing plate is generally designed with rivets and holes for installation on the caliper, therefore, the production processes are various and accuracy requirement is high.

At present, in the industry, the conventional punching process is the main production method. The main production equipment are mechanical presses. Some factories will use traditional hydraulic presses in some processes.

The control of quality is difficult in the production process with mechanical press and traditional hydraulic press. The production with mechanical press has a great impact on the service life of die. There is no domestic machine manufacturer to produce precision pressing equipment for backing plate. Some customers with high quality requirements will use imported fine blanking press which improves the quality of backing plate. However, the fine blanking press with price of several millions greatly increases the production costs. In addition, it is not conducive to flexible production with different specifications and in small batches, and affect the competitive advantage of enterprise.

Furthermore, the mechanical press generates great noise during punching process, so it is not environmentally friendly. Workers must wear ear protector for protection, the worse working environment cause difficulties in recruitment. With the improvement of urbanization, a factory which generates noise and is not environmental friendly is often complained, so the working time is greatly limited!

 

 

2.  Introduction to functional characteristics of Cosmos servo driven hydraulic press

Automobile brake pads are vulnerable parts with large production volume. With the rapid growth of the automobile market and the increase of automobile owner, all automobile brake pad manufacturers are expanding their plants to increase productivity, and new manufacturers are also running into the market.

To meet the needs of customers, Cosmos Press, under the support of the group’s strong R&D strength, has launched a special environmentally-friendly, low noise level and efficient servo driven hydraulic press for production of backing plates. The machine matched with the molds can fully cover the typical production processes of backing plates including 1.chamfer forming; 2.stamping; 3.pin forming and 4.fine stamping;

At the beginning of the design, the characteristics of “large quantity and low price” of backing plate production were known. On the premise of meeting the function, the costs of the equipment should be minimized, and the redundant design should be well controlled, to ensure that each kilogram of steel of the equipment is useful, and each component is appropriate at this position.

 

 

3. Advantages of Cosmos servo driven hydraulic press

3.1 Compact structure, easy operation, and automation

This machine is different from the traditional small table hydraulic press. Its hydraulic electrical system is reasonably designed and arranged on top. It is compact, has no obstacles around the machine, and is convenient for operation and installation of the mold. It does not affect the placement and handling of products. It is deeply favored by the workers on site. There is no obstacle around. Therefore, neither single machine automation nor multi-machine automation is affected. The production mode of multi-machine automation device reduces the manpower.

 

 

3.2 Rigid and lightweight machine body structure

The machine body structure avoids the “short, flat and fast” method of the small table machine, that is, three platens are made of heavy steel plates to achieve the purpose of rapid design and production. The three platens composed of top platen, moving bolster and fixed bolster are made of high-quality nodular cast iron. The reinforcement structure adjusted by finite element analyses is more reasonable, enhance good strength and small stress deformation, and has more optimized weight and safety factor ratio. Therefore, it avoids the phenomenon of “the wool coming from the sheep”, i.e. customers spending more money on machine weight.

 

 

3.3 Low noise level, environmentally-friendly, high-speed and stable hydraulic system

3.3.1 Low noise level and environmentally-friendly

The optimized servo motor hydraulic pump system only generates approximately 70dB to 80dB noise level during operation, and almost doesn’t generate noise in idle time, which greatly reduces the noise problems in the working environment. The operator enjoys moving from mechanical press workshop to servo driven hydraulic press workshop. To a certain extent, it also reduces the pressure of labor recruitment.

3.3.2 Pressure and position accuracy

The moving position and the pressing pressure are controlled and detected by precision linear transducer and pressure sensor. The pressure sensor matched with servo driver control can realize stepless regulation of working pressure. The working pressure for production of large and small backing plates can be set according to demand, which improves the quality and stability of products, and improves the “uncontrollable pressure and vulnerable mold” during punching operation; the pressing pressure can provide data support for new product development according to the size and accuracy requirement of product.

3.3.3 High-speed response

The highlight of the hydraulic system is used of imported Rexroth directional valve matched with the domestic mature two-way large-flow cartridge valve technology which not only realizes high-speed response to meet the production efficiency, but also reduces the manufacturing costs of the high-speed hydraulic system. The specially designed cartridge valve system reduces the resistance of the hydraulic oil flowing at a high speed, reduces the calorific value and the energy consumption, ensures the long-term high-speed response without stuck phenomenon, and ensures 24 hours stable and automatic production of press hydraulic system installed with oil cooler.

3.3.4 Control system

The “PLC+ touch screen + servo driver” control can realize the intuitive and efficient setting of the process flow and parameters. The flexible pressing process is adopted. Based on current backing plate production process and years of experience, Cosmos Press’ machine contains most of the pressing technologies of production process in the market. It can do the pressing process that cannot be completed by the mechanical press, realize the flexible and multi-purpose use of one machine, reduce the expenses and floor areas of production line, and lower the production costs.

 

Instant and effective action prompts

 

3.3.5 Unique finishing process structure

Based on the requirements of production process of backing plate, the machine is designed with a special cushion cylinder structure for finishing process. The sheared edge zone and dimensions of backing plate produced by the customer’s mold with the cushion cylinder structure, can reach the precision requirement from main engine factory. A special proportional pressure valve is equipped on the two-way cartridge valve to realize the floating blank holding force during finishing. By adjusting the floating blank holding force, the sheared edge zone of finished backing plate can meet the requirements. Besides, under the support of the floating force, the geometric dimensions of the previous processes of the backing plate will not be affected. A certain leveling effect will also be achieved.

Equipped with a special mold frame, it can be used in the reverse finishing process, that is, the ram cylinder is used for pressing and leveling, and the cushion cylinder is used for finishing. This process action is applicable to products requiring high leveling force.

The finishing process meets the quality requirements of backing plates. Three or four machines are combined to form an automatic line for production of backing plates. Customers do not have to spend millions on purchasing imported machines. It reduces the production costs of products, realizes the flexible production with different specifications and in small batch, and improves the product competitiveness.

4. Other advantages

4.1 Energy saving

The servo motor as the power source of machine. In working, it outputs the torque according to the real-time loads. Its power loss is small, 50% less than the traditional induction motor fixed with displacement pump, and at least 30% less than the traditional induction motor with variable pump.

4.2 High productivity

Its productivity is equal to that of mechanical press. It can complete punching action within 1.3s-1.6s and complete finishing action within 1.7s-2.3s.

 

 

5. Conclusions

Its successful development has solved three problems in traditional brake pad production process with mechanical press, i.e. “difficult recruitment & low per-capita productivity, noisy and high energy consumption”, relieves the pressure of environmental protection of an enterprise in production, greatly improves the product competitiveness, creates profits for users, and makes contributions to the development of automobile industry in China.

Chinese Creation of German Heritage | DEKUMA Brand Story

1. Hardship in plastic machinery development

 

Since 2002, with China’s reform and opening-up policy, its economy rapidly grew and there was a strong demand for rubber and plastic machinery and equipment from different industries. The Chinese manufacturing industry’s knowledge and technical skills in the rubber and plastic machinery industry was well behind other foreign countries’, causing local domestic manufacturing companies to be dependent on imported machines. European and American equipments were more advanced, but they were expensive. Shipments were also slow and after-sales services were mostly unresponsive. If the machines or components were damaged when received and required re-ordering, the lead-time usually took at least one or two months for another shipment. This greatly hindered China’s rapidly growing manufacturing industry.

 

 

Some European manufacturers realized the opportunity for business development in China, and decided to invest and set up factories in China. Only a few of them were successful in setting up their manufacturing facilities and developing their own brands in China, most of them were unable to take any market shares in the Chinese market due to a lack of understanding of Chinese law, culture, the market, etc.

 

2. Awakening of the industry

 

There are always pioneers in the market.
 
Some of these ‘pioneers’ of the local rubber and plastics machinery industries invested a vast sum to buy blueprints from European companies hoping to gain some breakthroughs.
Some of them chose to produce the machinery strictly according to the blueprint, but the products were way below the acceptable standards when comparing to the imported ones.
While other pioneers chose to use the blueprints as a reference which ended up making products which were just similar to those they produced locally.
 
A number of pioneers even tried the reverse-engineering upon purchasing of those overseas machinery, tools and products, aiming to integrate others’ advance technologies into their production but in vain. The essence of materials, engineering and techniques were not captured.
3.  Journey to Germany technology

Amid the industry’s development, we questioned if a machine with high performance and reasonable production cost was really impossible, and whether high-end rubber machines can only be used in niche markets.

 

For several years, the core management team of Cosmos Machinery Enterprises Ltd. (Cosmos) had been searching for solutions.

Cosmos is a Hong Kong listed company with more than 40 years of  experience in machine manufacturing, industrial product trading, and manufacturing of plastic products. Cosmos has been one of the market leaders in machine manufacturing in China Mainland, with an ample source of quality customers and suppliers. Our strong sense of brand awareness and quality control have demonstrated asuccessful model more capable than our mainland counterparts. In addition, Cosmos has an advanced and extensive capacity forproducing and processing rubber machinery as well as the rich experiences in collaborating with some international partners. More importantly, the core team in Cosmos could communicate well and exchange ideas with Europe counterparts, which would help us understand and develop necessary knowledge and skills in advancing our technology.

 

With Cosmos recognizing the importance of manufacturing its rubber machineries on its own, it then built a machining center in the 1990s, which has possessed a strong processing and production capacity.

 

 

In order to enhance the competitiveness of China’s rubber and plastics machinery and equipment industry, and reduce the dependency on imported equipments, it was important to develop the ability to build our own high-end equipments, that is why Cosmos’ executives have conceived a uniquesolution.

 

DEKUMA GmbH Deutsche Kunststoff Maschinen

 

At the beginning of 2002, Cosmos leaders formed a small team of experts in Germany with knowledge of Chinese cultures and the machine industry.
With mutual understanding among the team members, they dedicated themselves to establish along-term collaborating relationship aiming to develop state-of-the-arttechnologies in the machine manufacturing industries in the Chinese market. Hence, this team in Europe founded “Dekuma GMBH” (“Dekuma” is short for German plastic machinery), a small tech company.
They rapidly started designing and producing their first Dekuma rubber equipment. It is worthwhile to mention that Cosmos leaders did not relocate the team back to China as they recognized the importance of having an independent R&D team in Germany, where it could enjoy a strong and positive atmosphere in technological research, and thus allowing its designs to carry German’s attributes.
4. The foundation of extraordinary quality
“Dekuma GMBH” had the European team working in different components in R&D. Such as creating the design, digital application, equipment optimization, etc. Their design was then manufactured in China Mainland, with the European team completing the testing for the equipments to ensure strict quality control. Dekuma’s first generation of rubber machines were repeatedly designed, tested and amended. After 2 years or so, they were able to find a perfect balance between ‘Made in China’ and ‘Designed in Germany’, and the German-designed products at Cosmos at that time was produced and its quality and performance was also recognized by German experts.
 
After the success of having the first-generation equipment, the entire Dekuma GMBH team officially brought their research results to China in 2004, and jointly established “Dekuma Rubber & Plastic Technology (Dongguan) Co.,Ltd.” with Cosmos in a way that Dekuma GMBH was investing their technological expertise to this Joint Venture.
Since the integration of the German team into the company, workers in Cosmos frequently heard the word ‘rubbish’ from their German counterparts (the quality standards between countries were different backthen). Germans are extremely strict with manufacturing qualities, down to the smallest step of using the specific tool for a specific part. For example, during installation, each screw should be screwed in with it’s specific screwdriver, each bolt must be marked and tightened a second time, slits must be measured with a specific measuring tool, all equipments’ corefunctions must undergo a 24 hour no-fail checkup (all must be redone if thetest fails at the last second).
 
It is precisely because of the strict requirements of the German team that Dekuma can gradually grow through their constant guidance. Subsequently we understood the importance of precision in each of the workflow in their production plants, many starproducts such as the first pipe extrusion production line, China’s largest 2800-ton horizontal rubber injection machine, and a full-section rubber track forming machine were continuously produced in Dekuma and could be exported internationally with positive response. Since then, the soul of German engineering has been integrated into Dekuma’s DNA.
5. Towards the niche market

With the continuous competitive environment across all industries, the competitive edge of Dekuma’s standard was being challenged, and more importantly, both domestic and foreign customers urgently needed customized equipment to enhance their competitiveness.

In order to satisfy the upgrading needs of customers, Dekuma turned its attention to the niche market segments in 2012 and began actively paying attention to theirneeds by continuing the technological innovation and continuous research and development.

 

Although there was still a gap between Dekuma’s equipment and imported equipment, the gap was narrowing rapidly. Comparing with foreign branded equipment, some of Dekuma’s most significant competitive edges are rapid response, effective technical exchanges in early stages, timely equipment delivery, equipment installation and  optimization, and quick solutions to problems encountered by customers… These characteristics could be the real solution for problems of efficiency encountered during the rapid development of all Chinese manufacturers.

 

Among different niche market application, Dekuma has been highly recognized by our users such as from automobile nylon tubing, rubber track, the microduct cables, hydraulic press for brake pad sectors thanks to our strong R&D, perseverance and our willingness to customize products for our clients.

 

6. China’s smart manufacturing journey

 

Germany’s “Industry 4.0” strategy is the fourth industrial revolution led by smart manufacturing, using the “Internet+” approach to push traditional manufacturing towards smart manufacturing, especially in the fields of equipment manufacturing, drive and electrical engineering.
 
For example, structural designs, material used, craftsmanship and precision are some of the factors that made superb mechanical parts of the plastic equipments, the truly determining component has to be the drive and motion control system, it decides the equipment operation, coordination of the machine processing, compatibility and  specifications.
 
Relying on Cosmos’ technology in digital engineering and automation, Dekuma has become a leading manufacturer in the industry by transforming the term ‘Made in China’ into ‘Smart manufacturing in China’. Dekuma has a strong R&D team in drive and motion control. The quality control algorithm for each equipment produced by the company is continuously optimized by the team according to their deep understanding of users’ procedures, product conditions, etc. This program is also a core technology in Dekuma. Compared with the general control algorithms, self-developed algorithms can greatly improve the overall performance of the equipment.

 

With the continuous investment in research and development in smart manufacturing and automation, Dekuma’s “Smart manufacturing result” has been highly recognized by customers, industries and even awarded by the nation.
Dekuma was subsequently awarded with the “Top 30 Comprehensive Strength Enterprises of China Plastics Machinery Manufacturing Industry”, “Chinese National Science and Technology Progress Award”, “Guangdong Province new Specialized Enterprise”, “First (set) key technical equipment certification”and other honors.
Most of Dekuma’s customers are high-end users in the industry, and its products are exported around the globe such as the United States, Europe, Latin America, the Middle East, and Southeast Asia, and are used in different fields including auto parts, building materials, energy transmission, and electronic communications. This helps the technological innovation and facilitates “smart manufacturing” of  various industries.
With continuous innovation, state-of-the-art technology and strict quality control, Dekuma is advancing in the high-end  plastics and  rubber machinery industry as a visionary market leader locally and internationally in the future to come.
