AI Technical Summary

Technical Problem

In existing chipless cutting machines, the clamping device causes the fixed clamping block to come into contact with the pipe fitting when the pipe fitting is released, resulting in surface scratches and affecting the quality of the pipe fitting.

Method used

The clamping device with an inclined block structure uses a clamping drive to drive the lifting block to move the inclined block, so that the conforming clamping blocks move closer or wider to clamp and release the pipe fittings, avoiding scratching the pipe fitting surface.

Benefits of technology

It avoids scratching the pipe surface when the clamping mold returns, improving the surface quality of the pipe, and improves clamping accuracy by realizing the synchronous opening and closing of the clamping blocks through a single cylinder.

Abstract

This utility model provides a pipe clamping mold for a chipless cutting device, including a clamping drive and a lifting block connected to the clamping drive. The lifting block has a first inclined block and a second inclined surface. The first inclined block has a first inclined surface, and the second inclined block has a second inclined surface. A first contouring clamp and a second contouring clamp are positioned between the first and second inclined blocks, facing each other. The first contouring clamp has a third inclined surface that mates with the first inclined surface, and the second contouring clamp has a fourth inclined surface that mates with the second inclined surface. A spreading spring is provided between the first and second contouring clamps. This utility model avoids scratching the pipe surface during the return movement of the clamping device to the initial position, thus preventing damage to the pipe surface.
