In actual production, common technical tests similar to the stamping process, such as drawing performance test and bulging performance test, are used to check the stamping performance of the material to ensure the quality of the finished product and a high pass rate.
The precision and structure of the mold directly affect the forming and precision of stamping parts. Die manufacturing cost and life are important factors that affect the cost and quality of stamping parts. Mould design and manufacturing requires more time, which extends the production preparation time for new stamped parts.
Standardization of mold bases, mold bases, guides and development of simple molds (for small batch production), compound molds, multi-station progressive molds (for mass production), and the development of rapid die change devices can reduce the amount of preparation work for stamping production And shorten the preparation time, which can be applied to reduce the amount of preparation work for stamping production and shorten the preparation time, which can make the excellent stamping technology suitable for large-scale production reasonably applied to the production of small batches of multiple varieties.
Except for the forming of thick plates with hydraulic presses, stamping equipment generally uses mechanical presses. Conveying and other machinery, as well as mold library and rapid die change device, and controlled by computer program, can form a high productivity automatic stamping production line.
In the case of producing dozens or hundreds of stampings per minute, the processes of feeding, stamping, discharging, and waste disposal are completed in a short time, and personal, equipment, and quality accidents often occur. Therefore, safe production in stamping is a very important issue.
Generally, during the stamping process, the temperature will rise quickly during the stamping process, especially during the cold forging stamping process. Lubricating products must be lubricated. If you do not use lubrication and directly stamp, weld-assemble, there is no oil on the surface The parts are easy to weld and assemble. Research and practice have shown that Ameco metal inert gas arc welding, tungsten gas shielded arc welding and resistance welding have excellent results.
