Mold Design using 3D parametric design. Achieved a range of plate forming mold design, mold to the same mode of production. Die CNC machining technology, including EPC technology, the refinement of programming, high-speed processing technology, face NC technology to strengthen and repair. ????? Third, stamping die manufacturing technology development trends: (1) manufacturing stampings with traditional metal materials, are gradually being high-strength steel plate, coated steel plating, plastic laminated steel and other composite materials or polymer materials substitution. With the development of materials science, strengthen the research of new materials stamping performance, continuous development and improvement of metal forming technology. ????? (2) fine blanking and semi-fine blanking, hydroforming, spinning forming, explosive forming, electric water forming, electromagnetic forming, superplastic forming, such as technology development and applications, some of the traditional processing methods will be stamping their replaced by punching processing products become more reasonable and more economical. Fine Blanking technology which has been relatively rapid development, Fine Blanking is an advanced manufacturing technology, can be used to replace certain parts machining with high-quality, high efficiency, low consumption, application characteristics of Canton. Gear plate in terms of fine blanking, in ordinary hydraulic fine blanking machine, technique and equipment is simple and precision workpiece. Its sheet metal as raw material, the use of less without cutting the plastic processing methods, one can get the size shape and high precision, low-shear surface roughness of the parts, the use of fine blanking technology known as fine blanking parts, pieces. (3) With the development of computer graphics technology matures, the field of metal forming in recent years the rise of the computer-aided design (CAD), computer aided engineering (CAE) and computer-aided manufacturing (CAM) technology. The technology of traditional stamping technology changes have had an important impact. Especially the numerical simulation of sheet metal forming technology, so that sheet metal forming technology to rid itself of the "experience" and "qualitative" level, has entered a "scientific" and "quantitative" stage of development. The use of this technology for sheet metal forming process simulation, you can predict metal stamping process flow, stress and strain and thickness distribution, die by the strength and wrinkle, break down, the impact of lines of possible defects and failure mode. This is to optimize process parameters and die structure provides a very effective tool in reducing or even abolishing the test mode process, shorten the product development cycle and reduce the cost of product development plays an increasingly important role, has become the guiding mold design and optimization an important tool. ???? (4) high-speed milling process, both at home and abroad in recent years the development of high-speed milling process to improve the processing efficiency, and access to high surface finish. In addition, high hardness module can also be processed, also has a low temperature rise, thermal deformation of the small advantages. High-speed milling technology, automobile, home appliance industry, a large cavity mold manufacturing has injected new vitality. At present it has more agile, intelligent, integrated direction. ???? (5) die scanning and digitizing system, high-speed scanners and mold scanning system provides a model or in kind from the scan to be processed into the desired model number of the necessary functions, greatly reducing the mold in the development of the manufacturing cycle.

" Die scanning system has been in the automotive, motorcycle, household appliances and other industries has been successfully applied, I believe in the "Tenth Five-Year" period will play a greater role. ???? (6) high-quality materials and advanced surface treatment technologies, high-quality steel and application of the corresponding surface treatment technology to improve the life of mold it is very necessary. Mold heat treatment and surface treatment can give full play to the die steel material properties of the key link. Mold heat treatment is the development direction of vacuum heat treatment. In addition to improving the mold surface treatment technology should be developed advanced vapor deposition, plasma spraying techniques. Fourth, stamping machinery manufacturers in the position and characteristics: Pressing both capable of producing small-size instrument parts, but also capable of producing beams, such as automotive, pressure vessel head for a class of large parts; both capable of producing the general size and shape of the tolerance level of spare parts, also capable of producing precision (tolerances in the micron level ) and the complex shapes of parts. The world's steel production accounted for 60% ~ 70% of the plates, tubes and other profiles, most of which are made after stamping products. Stamping in the automotive, machinery, household appliances, electrical, instrumentation, aerospace, weapons manufacturing, a very important position. ????? Stamping parts of the light weight, thickness, stiffness good. Its size tolerance is guaranteed by the mold, so the quality of stability, in general no longer be used by mechanical cutting. Cold metal stampings and mechanical properties superior to the original blank, smooth surface appearance. Cold stamping tolerance level and surface state is superior to hot-stamping parts [6]. ????? Stamping production technology and equipment is growing, with the exception of the use of the traditional mold presses and steel stampings, the hydroforming and spinning forming, superplastic forming, explosive forming, electric water forming, electromagnetic forming a variety of special Stamping technology is also developing rapidly, the press raise the level of skills to a new height. Special metal forming process is particularly suitable for many species of small and medium-sized quantities (or even dozens of) parts production. For ordinary stamping process, to be used in simple mold, low melting point alloy die, die and stamping group flexible manufacturing systems, organizations and more species of small and medium-sized quantities of stamping parts processing. ????? In short, stamping die with high productivity, low processing costs, material utilization high, simple operation, easy to achieve mechanization and automation are a number of advantages. The use of stamping and welding, bonding and other composite process, so that more reasonable structural parts, processing more convenient, you can use relatively simple technology to create more complex structure.
