Research on Multi-die Stamping Process of Steel Bar Accessories Text / Huang Xiaolin Metal packaging is an important part of China's urban industry. It is an irreplaceable traditional packaging method with its unique reinforcement, sealing and storage, and metal decoration charm. Its output value accounts for about 10% of the total output value of China's packaging industry, mainly providing services for food, canned food, beverages, oils, chemicals, pharmaceuticals and cosmetics, and export gift packaging. According to the report of the Metal Packaging Committee of China Packaging Federation, China has become the world's second largest metal packaging country. China's metal packaging industry still has huge room for development. New listed companies and leading enterprises are constantly emerging, and the level of enterprise modernization is getting higher and higher. In the field of metal container manufacturing, developed countries have reached a high level of automation. In recent years, China's metal printing and barrel technology has also shown a thriving and continuous development. As an indispensable accessory for metal containers, it has high technical requirements for manufacturing due to its many processes and difficult material forming. In recent years, the consumption of metal packaging containers has gradually increased, and the comprehensive market, resources, development prospects and other factors, the high-speed automated production line with automation and intelligence as the main direction and the research and development of its key technologies have become the direction of current industry technology development. . The developed countries in the metal packaging industry have already realized the automation of the barrel making process. Some domestic powerful companies have introduced similar automated production processes, and there have also been automatic barrel manufacturing processes and equipment. At present, there are still a large number of manual or semi-automatic operation equipments in China, and the production efficiency and operation methods are relatively backward. However, the introduction of new technologies means higher costs. Most enterprises in the metal packaging industry are still unable to introduce world-class high-tech products. Equipment or process. With the continuous transformation of our economic methods into intensive types and the changes in people's living standards and living concepts, people's requirements for product appearance, performance, quality, safety, etc. are getting higher and higher, and more and more metal packaging industry companies feel By the way, according to the current production process, the market has become less and less demanding. The development of new intelligent upgrade technology based on existing technologies and equipment and intelligent control technology is imperative. The research and development of this project can realize the upgrading and transformation of existing equipment, break through its original capacity limitation and maximize the rational use; on the other hand, it can reduce the labor intensity and achieve the product quality and stability. Upgrade. Through the implementation of this project, the company's production efficiency and production capacity can be greatly improved, and it also has outstanding significance in saving labor resources, saving raw materials, and saving energy. This project boldly introduces the tinplate feeding and stamping technology into the production process of metal container auxiliary parts, and realizes the double improvement of production capacity. It is important for the promotion and implementation of standardized parts projects in the future to improve the standardization process of auxiliary parts in metal packaging containers in China. The guiding role. The main technical innovations of the project are as follows: 1. Fully automatic CNC coil continuous feeding system This project develops direct automatic unwinding stamping technology and equipment for can lid/bottom steel coil. For the first time in China, it adopts volumetric punching and multi-mode technology to realize high-speed automatic production of auxiliary parts of various specifications, reduce the transfer of intermediate products and improve the stability of finished products. . Based on the automatic feeding system of tinplate coil material, the feeding is stable, accurate and the speed can meet the requirements of high-speed stamping, and the precise feeding of the whole volume of tinplate can be realized. The direct conveying and punching of the coil material can be realized, and the feeding mode of the steering can also save the row of the whole device. The cloth space makes the feeding more stable. 2. Alternating tangent type multimode system Alternate tangent type multi-mode system, research and development design multi-row mold and array operation, through the running-in between the head and the molding process, to maximize the speed of the two, to achieve multi-mode stamping. The sheet steel plate is unwound and conveyed to the mold; the mold has three stamping stations, firstly, the first stamping station presses the middle portion of the coiled steel sheet, and then the second and third stations simultaneously press the left and right sides of the coiled steel sheet. The blanking is completed; the left and right sides of the blank formed by the second and third stamping stations are tangent to the two adjacent edges of the coiled steel sheet; finally, the material is conveyed. 3. New waste continuous processing technology It solves the problem of how to deal with waste in the rolling process, the feeding and returning efficiency is high, the feeding and returning directions are accurate, and the feeding and returning materials are fully realized, and the production efficiency of the punching is greatly improved. The picking rod hooks the scrap, and the receiving rack moves to recover the scrap. The structure is simple, the use is convenient, the degree of automation is high, the labor is reduced, the equipment operation is more stable, and the production danger is reduced. 4, multi-mode multi-channel injection molding process The multi-mode injection molding process develops a multi-nozzle multi-channel injection molding technology to adapt to the production speed of ultra-high-speed stamping equipment, and achieves a significant increase in the injection speed. The driving structure of the three-mode injection molding machine can complete the injection of three flower basket covers in one operation, and the working cycle of the single injection molding is shortened, which improves the injection efficiency of the flower basket cover and meets the requirements of modern production. The multi-channel multi-layer baking process develops a new multi-channel multi-layer oven technology to adapt to the production speed of ultra-high-speed stamping equipment and achieve a substantial increase in baking speed. 5. Dynamic design and processing simulation and optimization of key components and equipment Key tank cover, tank bottom stamping, multi-station combination optimization of canning technology and equipment, focusing on transmission mechanism, feeding mechanism, rack, etc., based on the requirements of high speed, stable, low noise, wear resistance and reliable operation of equipment, Structural design and modeling of various institutions and key components, establishment of mechanism dynamics model, dynamic analysis; finite element analysis technology, modal analysis of the whole machine, components and key parts and dynamic load Strength analysis; comprehensive dynamics model and finite element analysis technology, multi-objective and multi-parameter optimization design method, optimize design of equipment structure system, focus on light weight of equipment structure, drive cam structure and shape optimization, high-speed operation Stationary reliability and so on. Issues to be further resolved: At present, the production speed of steel bucket auxiliary parts at home and abroad is generally 30~45/min. The equipment developed by this project is higher than the domestic level. The production lines of 3 steel bucket auxiliary parts currently in use exceed the highest production speed at home and abroad. Up to 105 / min, but limited by the local manufacturing process, currently only 80 / min. How to go from 80/min to 105/min is a major technical difficulty of this project. The problem of speed improvement mainly includes the following two aspects: (1) Electrical control. The electrical components used in the current industry have far exceeded the domestic conventional level, but there is still a certain gap from the leading level in foreign countries. Therefore, breaking the bottleneck of electrical control design is also a major problem to overcome the speed increase. (2) Injection molding. Due to the long curing cycle of the bottom seal of the steel bucket bottom cover, it becomes a bottleneck of multi-mode winding speed. Therefore, the new sealant curing process is adopted to effectively solve the disadvantage of long curing cycle, and it is also a key factor for the speed of the whole set of equipment in the future.

Before the project was established, the company has made technological breakthroughs in the intelligent production of auxiliary parts, equipment design and manufacturing, etc. The accumulated experience of previous projects provided reference for the research and development of the project. The innovations of the R&D Center in recent years laid the foundation for the project. Multi-mode reeling production equipment research and development adopts coil material production, which replaces the traditional coil material production method after the leveling process, and saves the leveling process, which shortens the product production cycle, reduces the energy consumption per unit product, and reduces the employee input. A great breakthrough, the multi-mode stamping process used at the same time, changing the current status of single-die stamping to produce only one product at a time, is very obvious in improving the production efficiency of the product. Based on the above characteristics of multi-mode reeling production equipment, the production line will be scaled up and promoted, which will play a greater role in improving the company's market competitiveness, and the market prospect is broad. It has a good effect on improving the degree of intelligent automation of domestic metal packaging container production equipment.
Not only does it increase production efficiency, but the stability of equipment operation is also higher.
