使命召唤ol官网电脑版:The global automotive mold industry has shown nine development trends

Release date:2017-06-11 author: click:

使命召唤ol手游什么时候发布 www.hdxdh.icu At present, the global automotive mold industry presents nine development trends, namely: stamping process simulation (CAE) role is more prominent, mold three-dimensional design status to be consolidated, digital mold technology has become the mainstream direction, rapid development of mold processing automation, high strength Steel stamping technology is the future direction of development, the timely introduction of new mold products, mold materials and surface treatment technology will be reused, the management of scientific and information technology is the direction of development of mold enterprises, mold manufacturing is an inevitable trend.


Stamping process simulation (CAE) role is more prominent

 

In recent years, with the rapid development of computer software and hardware, stamping process simulation technology (CAE) play an increasingly important role. In the United States, Japan, Germany and other developed countries, CAE technology has become a necessary part of the mold design and manufacturing process, widely used to predict the forming defects, optimize the stamping process and mold structure, improve the reliability of mold design and reduce the test time.

 

Many domestic automobile mold enterprises in the CAE application has also made significant progress, get a good effect. CAE technology can greatly reduce the cost of test mode, shorten the development cycle of stamping die, has become an important means to ensure the quality of the mold. CAE technology is gradually turning mold design from empirical design to scientific design.

 

Mold three-dimensional design status to be consolidated

 

The three-dimensional design of the mold is an important part of the digital mold technology, is to achieve mold design, manufacturing and inspection integration basis. Japan Toyota, the United States and other companies have achieved the mold of the three-dimensional design, and achieved good results. Abroad in the mold three-dimensional design to take some of the practice worthy of our reference. In addition to the three-dimensional design of the mold is conducive to the realization of integrated manufacturing, the other advantage is to facilitate the interference check, can be carried out motion interference analysis to solve the two-dimensional design of a problem.

 

Digital mold technology has become the mainstream direction

 

In recent years, the rapid development of digital mold technology, is to solve the development of automotive mold in many of the problems faced by an effective way. The so-called digital mold technology, is the computer technology or computer-aided technology (CAX) in the mold design and manufacturing process applications.

 

Summary of domestic and foreign automotive mold enterprises using computer-aided technology, the successful experience of digital automotive mold technology mainly includes the following: 

① manufacturability design (DFM), that is, in the design and analysis of manufacturability to ensure the success of the process. 

② mold surface design of the auxiliary technology, the development of intelligent surface design technology. 

③ CAE auxiliary analysis and simulation of stamping process, to predict and solve the possible defects and forming problems. 

④ with three-dimensional mold structure design to replace the traditional two-dimensional design. 

⑤ mold manufacturing process using CAPP, CAM and CAT technology. 

⑥ under the guidance of digital technology to solve the trial process and stamping production problems. 

Mold processing automation rapid development 

Advanced processing technology and equipment is an important basis for improving productivity and ensuring product quality. In the advanced automotive mold enterprises, equipped with dual-table CNC machine tools, automatic tool changer (ATC), automatic processing of the photoelectric control system, the workpiece on-line measurement system is not uncommon. CNC machining has been developed from a simple surface processing to the surface and the structural surface of the comprehensive processing, from low-speed processing to the development of high-speed processing, processing automation technology is developing very rapidly. 

High strength steel stamping technology is the future direction of development 

High strength steels have excellent characteristics in terms of yield ratio, strain hardening characteristics, strain distribution ability and impact energy absorption, and the use of automobiles is increasing. At present, the use of high-strength steel stamping parts are mainly hardened steel (BH steel), duplex steel (DP steel), phase change induced plastic steel (TRIP steel) and so on. 97% of the advanced concept vehicle (ULSAB-AVC) is a high-strength steel, and the proportion of advanced high-strength steel sheet in the vehicle will exceed 60%, and the proportion of duplex steel Will account for 74% of automotive steel. Now, a large number of IF steel-based series of mild steel will be replaced by high-strength steel plate series, high-strength low-alloy steel will be dual-phase steel and ultra-high strength steel instead. 

At present, the application of high-strength steel parts of domestic auto parts is also limited to structural parts and beam parts, the tensile strength of materials used in more than 500MPa below, therefore, quickly grasp the high-strength steel stamping technology, China's automobile mold industry needs to be solved important question. 

New mold products introduced in due course

With the development of automotive stamping production and automation, progressive die in the production of automotive stamping parts will be more widely used. The complex shape of the stamping parts, in particular, according to the traditional process requires a number of pairs of punching process of small and medium-sized complex stamping parts, more and more use of progressive die forming.

Progressive die is a high-tech mold products, technical difficulty, high precision manufacturing requirements, long production cycle. Multi-station progressive die will be one of China's key development of the mold products.

Mold materials and surface treatment technology will be reused

The quality and performance of the mold material is an important factor affecting the mold quality, life and cost. In recent years, in addition to constantly have a variety of high toughness and high wear resistance cold work die steel, flame quenching cold work die steel, powder metallurgy cold work die steel introduced outside the large and medium-sized stamping die cast iron material is a worth Attention to the development trend. Ductile iron has good toughness and abrasion resistance, its welding performance, machinability, surface hardening performance are also better, and the cost is lower than the alloy cast iron, therefore, in the automotive stamping die application more.

Management of scientific and informatization is the development direction of mold enterprises

Another important aspect of the development of automobile mold technology is the scientific and informative management. The scientific management of the mold business enterprises continue to punctual manufacturing (Just-in-TimeManufacturing) and lean production (LeanProduction) direction, enterprise management more accurate, a substantial increase in production efficiency, ineffective institutions, links and personnel continue to streamline. 

With the development of modern management technology, many advanced information management tools, including enterprise resource management system (ERP), customer relationship management (CRM), supply chain management (SCM), project management (PM), etc., in the mold business Widely used.

The fine manufacturing of molds is an inevitable trend 

The so-called mold manufacturing, is the mold of the development process and manufacturing results, the specific performance: stamping process and mold structure design rationalization, mold processing of high precision, mold products, high reliability and technical management Tightness. Mold refinement of the manufacturing is not a single technology, but the design, processing and management of a comprehensive reflection of technology. Mold refinement of the realization of manufacturing, in addition to relying on technical excellence, but also rely on strict management to protect.
