The punching / hole flanging die can greatly improve the production efficiency and guarantee the product size after being put into practical production.

Description

technical field [0001] The invention relates to a mold for manufacturing an inner support tube of an automobile shock absorber, in particular to a punching belt turning hole mold for an inner support tube of an automobile shock absorber. Background technique [0002] At present, the inner support tube of the automobile shock absorber is completed by punching the bottom hole first and then turning the hole. Due to the two processes, there is a positional error between the bottom hole before turning the hole and the turning hole, and the error makes the turning hole When the product is turned over, the height of the hole is not uniform, and the product size requirement cannot be met. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a car shock absorber that combines punching and turning holes together, so that the position of punching and turning holes has no error, and can ensure the uni...
