Abstract

The invention relates to a fixing-sleeve-replaceable punching die comprising an upper die plate and a lower die plate. Two guide pillars are fixed in the middle of the lower die plate, two guide sleeves are sleeved on the two guide pillars respectively, a support block is arranged between the two guide pillars, a mandrel fixing block and the support block are mounted on the lower die plate, an adjusting plate is disposed between the mandrel fixing block and a support frame, a profiling fixing plate is mounted on the adjusting plate, a punch fixing plate is mounted on the upper die plate, a punch is mounted on the punch fixing plate, a mandrel is mounted on the mandrel fixing block, and the fixing sleeve is mounted on the mandrel. The fixing-sleeve-replaceable punching die is simple in structure, ingenious and reasonable; since a counter bore is added on an existing mandrel for mounting one fixing sleeve, so that the mandrel can be protected; the mandrel cannot be replaced, and the original mandrel can be reused by only replacing the fixing sleeve.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a die used for punching pipe fittings, in particular to a punching die capable of replacing a fixed sleeve. Background technique [0002] In the existing technology, the mandrel of the pipe fitting is easily damaged during the punching process. The usual method is to replace the mandrel. The operation is cumbersome and the work efficiency is low. In order to improve this situation, this mold is specially designed. Not only can meet the technical requirements, but also improve work efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a simple, ingenious and reasonable punching die, which can realize the reuse of the original mandrel without replacing the mandrel. The punching die of the replaceable fixed sleeve. [0004] According to the technical solution provided by the pr...
