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

The punching die of replaceable fixed cover

Technical field

The invention belongs to Machining Technology field, relate to a kind of mould for pipe fitting punching processing, specifically a kind of punching die that can change fixed cover.

Background technology
