A precision machining process for stamping process of thin film parts

Abstract

The invention relates to a precision machining process of a film part stamping process, comprising the following steps: (1) fixing a stamping assembly in a stroke module through a threaded connection, the stamping assembly includes a stamping upper die, and is fixedly connected to the stamping upper die Adjusting ruler on the top; (2) debugging stamping: start the stroke module to carry out a stamping, when the stroke module moves downward, rotate the adjusting ruler to make the stamping upper die and the stamping lower die contact each other, and record the adjustment ruler and the stroke The scale on the upper surface of the module is flush; start the reset of the stroke module, and then according to the thickness d of the film part to be processed, the rotation adjustment ruler moves down relative to the stroke module by h, h=d; (3) Place the film part to be processed on the stamping lower die , start the stroke module for stamping. The process provided by the invention can avoid "wrinkling" of parts caused by excessive stamping depth, which will damage the surface smoothness of film parts; and avoid damage to mold equipment caused by too deep cutting of blades.

Description

technical field

[0001] The invention belongs to the field of production and manufacture of precision parts technology, and in particular relates to a precision processing technology of a stamping technology of film parts. Background technique

[0002] The stamping process in the prior art generally adopts program control, and the parts to be cut are placed on the processing bed, and then the stamping process is performed using a program-controlled blade. Doing so can be applied to mass production processes. However, the processing requirements of some precision parts are very strict, especially the cutting process of some film parts, which requires precise adjustment of the mold to control the punching depth of the blade. However, for most stamping processes, the method of changing the program to control the depth of stamping is very cumbersome, which is not conducive to the needs of actual production. Moreover, due to the limitation of the production method, the adjustmen...
