Stamping die finishing technology

According to the traditional manufacturing method of stamping die, the surface processing is adopted: rough machining→semi-finishing finishing→cleaning root. After turning to assembly, fitters generally use a grinder to polish, then use coarse oilstone for polishing, and finally use fine oilstone for polishing. This often causes two problems. One is that the profile is damaged. Normally, it is normal for the profile to have an error of 0.1-0.2mm due to the grinding wheel repair. On the other hand, the fitter's repair and assembly cycle will be longer. Cutting edge processing of trimming molds The cutting edge processing of trimming molds is usually processed first, quenched with a reserved amount, and finally studied by a fitter one by one. In this way, the assembly accuracy and cycle cannot be guaranteed. The dimensional accuracy also varies to a certain extent due to the research, which often results in uneven gaps and large trimming burrs. Introduction to the fine processing of profile and trimming edges The fine processing technology has been greatly improved on the basis of inheriting traditional processing methods. The quality of chemical nitrogen production models has been greatly improved, and parts can be pressed without research and distribution. The clearance qualification rate of the trimming edge reaches more than 75%. Reduce fitter's assembly and research time by 30% to 40%, greatly improving quality and efficiency. Directly reduce the cost up to 548 yuan / standard set (a standard door outer panel drawing and research mold is a standard set). Refined surface processing The processing route of surface refined processing: rough root removal 50—rough processing 50—semi-finishing root removal 32—semi-finishing processing 32—fine cleaning root 30—finishing processing 30—fine cleaning Root 20-fine and clear root 16-fine and clear root 12-fine and clear root 10-fine and clear root 8-fine and clear root 6-fine and clear root 4.
