Stamping die for auto parts and using method thereof

Abstract

The invention discloses a stamping die for auto parts and a method for using the same. block one. The method includes the following steps: S1, placing the workpiece to be punched on the lower platen, and then opening the cylinder, and the cylinder works to drive the upper platen, the boss, and the magnetic block to move downward together. The advantage is that when the first magnetic block moves downwards, the second magnetic block drives the return plate to move downwards, which can perform a pressing and fixing effect on the workpiece placed on the lower pressing plate to ensure the punching accuracy, and this part is arranged outside the lower pressing plate, and does not It will reduce the impact resistance of the lower pressing plate, and it is also convenient to take and place the workpiece; at the same time, the continued movement of the magnetic block 1 will make the two magnetic blocks 2 in the corresponding chute far away from each other, thereby further slowing down the impact force on the lower pressing plate , to avoid mold damage caused by excessive impact force.

Description

technical field [0001] The invention relates to the technical field of auto parts production, in particular to a stamping die for auto parts and a method for using the same. Background technique [0002] Auto parts need to be stamped by stamping dies in the production process, but the traditional stamping dies do not have any buffer function during the specific operation process, and the impact force generated during the stamping process is relatively large, which may easily cause damage to the dies. [0003] The authorized invention patent document with the patent number CN108437535B discloses a stamping die for auto parts, including a base, a plurality of support feet are fixedly installed on the bottom of the base, and a gantry is fixedly installed on the top of the base, and the gantry is Both sides are set as a hollow structure with openings. [0004] Although the stamping die has solved the problems of the traditional die, it still has the following deficiencies: 1. T...

AI Technical Summary

Problems solved by technology

[0004] Although the stamping die has solved the problems of the traditional die, it still has the following deficiencies: 1. The buffer and damping part is arranged in the lower platen, which reduces the overall impact resistance of the lower platen; The compression effect produced by the spring is used for cushioning and shock absorption. When the extrusion force is lost, the limit block will move up quickly under the elastic action of the spring and collide violently with the top wall of the limit groove, which may easily cause damage to the limit hole; 3. It does not provide a fixed effect for the stamped workpiece before stamping, which is easy to affect the stamping accuracy
