Description

Stamping die for side holes of pipe fittings Technical Field The invention relates to the technical field of pipe fitting stamping, in particular to a pipe fitting side hole stamping die. Background At present, a side hole of a hollow pipe is usually machined by adopting a stamping die, the stamping die comprises an upper die and a lower die, the upper die is arranged above the lower die and can move along the up-down direction relative to the lower die, a core die capable of being inserted into the pipe to support and position the pipe is further arranged between the upper die and the lower die, and the upper die is provided with a stamping part for punching the pipe. During processing, the pipe fitting is required to be sleeved on the periphery of the core die, and then the stamping part is driven to move downwards through the upper die, so that the side wall of the pipe fitting is stamped and punched. In the process, if the pipe fitting is manually sleeved on the periphery of the core mold, the efficiency is low, if the pipe fitting is pushed by the pushing mechanism to move close to the stamping die so that the pipe fitting is sleeved on the periphery of the core mold, the pipe fitting and the core mold need to be ensured to be axially aligned, if the positions of the pipe fitting and the core mold deviate, the core mold is easily caused to be incapable of being inserted into the pipe fitting, and even the end part of the core mold and the end part of the pipe fitting possibly collide to damage the pipe fitting and the core mold.
