Positioning and punching mold of automobile part

Abstract

The invention provides a positioning and punching mold of an automobile part. The positioning and punching mold of the automobile part comprises an upper mold cover, a lower mold base, a positioning surrounding plate and a base plate, wherein the lower mold base is arranged on the base plate, the positioning surrounding plate is arranged on the periphery of the lower mold base, a fixed cavity is formed between the positioning surrounding plate and the lower mold base, the upper mold cover is arranged right above the lower mold base, the upper mold cover comprises a side plate matched with thefixed cavity, ball grooves are formed in the outer wall of the lower mold base and the inner wall of the positioning surrounding plate, and a plurality of balls are uniformly distributed in the ball grooves. According to the positioning and punching mold of the automobile part, the vibration of materials and a mold is effectively prevented, the positioning of the positioning and punching mold is accurate, and the structure is simple.

Description

technical field [0001] The invention relates to the field of stamping dies for auto parts, in particular to a positioning stamping die for auto parts. Background technique [0002] Stamping is a pressure processing method that uses a stamping die to apply pressure to a sheet on a press to cause plastic deformation or separation to obtain parts of the desired shape and size. In the manufacture of automobiles, some parts are usually obtained by stamping. Due to the great impact force of the punch on the mold during stamping, the mold will vibrate greatly at the moment of impact, which will cause vibration to both the material and the mold, and will cause The machining accuracy of parts is reduced. At present, inaccurate positioning accuracy in the stamping process of auto parts leads to low processing accuracy, slow production efficiency, low assembly efficiency, and greatly increases production costs. Contents of the invention [0003] In view of this, the present inventi...
