Description

technical field [0001] The invention relates to a stamping die processing technology, in particular to a concave die processing technology. Background technique [0002] The punch and die are two important components of the stamping die. The processing technology of the punch and die determines the service life and the dimensional accuracy of the product. The processing technology of the die in the prior art is relatively complicated. The die hole or the cavity of the die is processed by wire cutting, and the wire cutting is processed by fast wire cutting. Require. Contents of the invention [0003] 【1】Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a die processing technology with reasonable process arrangement and high processing precision. [0005] 【2】Technical solution to solve the problem [0006] A kind of die processing technique is characterized in that, comprises the following steps: [0007] ...
