The great influence of scientific development on cold extrusion technology
At present, China has been able to cold extrude metals such as lead, tin, aluminum, copper, zinc and their alloys, low carbon steel, medium carbon steel, tool steel, low alloy steel and stainless steel, and even for bearing steel, high carbon and high carbon steel. Aluminum alloy tool steel, high-speed steel, etc. can also be cold extruded with a certain amount of deformation. In the use of mold materials, in addition to high-speed steel, bearing steel, high-carbon and high-chromium alloy tool steel, many new mold steels such as CG2, 65Nb, LD, etc. are also used. In terms of extrusion process parameter selection and die structure design, optimized design and computer-aided design and manufacturing (ie CAD/CAM) were initially adopted to make the die structure more reasonable and the extrusion process parameters closer to reality. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to the use of general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have been successfully used for cold extrusion production.
The development of science has had a significant impact on cold extrusion technology, specifically the impact of the application of computers in process analysis, mold design, manufacturing and process control on cold extrusion technology. Our country will further develop and apply this new technology. The development of cold extrusion technology should mainly start from the following aspects:
1. Expand the application range of cold extrusion technology and gradually replace casting, forging, deep drawing and cutting within a certain range;
2. Improve the precision and surface quality of cold-extruded parts, and produce parts with more complex geometric shapes;
3. Expand the types of raw materials used in cold extrusion, and study more ideal surface treatment and lubrication methods;
4. Further use CAD/CAM and optimized design to improve and speed up mold design and manufacturing, and develop a more reasonable mold structure;
5. Looking for mold materials and heat treatment methods that are more suitable for cold extrusion to extend the service life of the mold;
6. Further develop the research and application of new technology such as warm extrusion, isothermal extrusion, hydrostatic extrusion and high-speed extrusion;
7. Develop a multi-functional cold extrusion machine suitable for cold extrusion, so that blanks and parts can be fed and discharged safely and automatically, so as to further improve productivity.
