The 3D design of die is an essential part of digital die technology and is the basis for the integration of die design, fabrication and inspection. Some of the practices adopted by foreign countries in 3D design of molds are worthy of our reference. In addition to being conducive to the implementation of integrated manufacturing, the 3D Stamped Die design has the additional advantage of being convenient for interferometric inspection and motion interferometric analysis, thus solving a difficult problem in 2D design. Software solutions for software management of software for Automotive Stamping Dies can help the automotive industry provide the most beneficial assistance.
The rapid development of digital die technology in recent years is an effective way to solve many problems in automotive die development. The so-called digital die technology is the computer technology or computer aided technology (CAX) in the die design and manufacturing process of the application. To sum up the successful experience of the application of computer-aided technology in automotive stamping enterprises at home and abroad, digital automotive stamping technology mainly includes the following aspects:
With the rapid development of computer software and hardware, the simulation technology of stamping forming process (CAE) plays an increasingly important role. CAE technology has become a necessary part of the die design and manufacturing process in many developed countries, and is widely used to predict form defects, optimize the stamping process and die structure, improve the reliability of the die design, and reduce die testing time. Many domestic automotive molding companies have also made significant progress in CAE application and achieved good results. The application of CAE technology can greatly save the cost of test dies and shorten the development period of stamp dies, which has become an important means to ensure quality of dies. CAE technology is gradually transforming Stamping Die design from empirical to scientific design.
Advanced processing technologies and equipment are an important foundation for improving productivity and ensuring product quality. In advanced automotive mould enterprises, CNC machine tools with double worktables, automatic tool changing device (ATC), photoelectric control system of automatic processing, on-line measuring system of workpiece are not rare. Numerical control processing has evolved from simple profile processing to comprehensive processing of profiles and structures, from medium and low speed processing to high speed processing, and processing automation techniques have evolved very rapidly.
High-strength steel is increasingly used in automotive applications due to its excellent properties in terms of flexural strength ratio, strain hardening, strain distribution, and energy absorption in collisions. At present, the high strength steels used in automotive stamping parts mainly include paint hardened steel (BH steel), dual phase steel (DP steel), phase change induced plastic steel (TRIP steel) and so on.
The mild steel series based on IF steel, which is now widely used, will be replaced by the high-strength steel series, and the high-strength low-alloy steel will be replaced by dual-phase steel and ultra-high-strength plates. Currently, the use of high-strength steel plates for automotive parts in China is mostly limited to structural parts and beam components, with most of the materials used having tensile strength below 500MPa. Therefore, quickly mastering high-strength steel plate stamping technology is an important issue that needs to be urgently addressed in China's automotive die industry.
With the development of high efficiency and automation in automotive stamping production, progressive dies will be used more widely in automotive stamping parts production. Is a kind of new and high technology of progressive die Stamping Die, technical difficulty is big, manufacturing high accuracy requirement, production cycle is long, multi-station progressive die is one of the focus on the development of Stamping Die products, shape of complex stamping parts, especially some vice die according to the traditional process need more points sequence system of small and medium-sized complex stamping parts, progressive die forming are used more and more.
The quality and performance of die materials are important factors affecting the quality, longevity and cost of dies. In recent years, in addition to a variety of die steels with high toughness and wear resistance, flame quenched die steels and powder metallurgical die steels have been introduced. The overseas selection of cast iron materials for large and medium-sized stamping dies is a noteworthy development trend. Ductile iron has good toughness and wear resistance, better welding performance, machinability, surface quenching properties, and lower cost than alloy cast iron, so it is used more in automotive stamping dies.
Another important aspect in the development of automotive die technology is scientific management and information. Scientific management has enabled the Stamping Die enterprise to continuously move in the direction of just-in-time manufacturing and lean production, with more accurate corporate management, greatly improved production efficiency and continuous simplification of ineffective organizations, links and personnel. With the progress of modern management technology, many advanced information management tools, including enterprise resource management system (ERP), customer relationship management (CRM), supply chain management (SCM) and project management (PM), have been widely used in Stamping Die enterprises.
The so-called die fine manufacturing, which is the development process and manufacturing results of the stamping die, is dedicated to the rationalization of the stamping process and the design of the die structure, high precision die handling, high reliability of the die product and technical management rigor. Fine manufacturing is not a single technology but a comprehensive reflection of design, processing and management techniques. The realization of fine manufacturing of Stamping Die depends not only on technical excellence, but also on strict management guarantees.
