Material clamping mechanism of taper pipe contracting machine

Abstract

The invention discloses a material clamping mechanism of a taper pipe contracting machine. The material clamping mechanism comprises a conveying assembly, a clamping assembly and a supporting base, wherein the conveying assembly is fixedly mounted at the top part of the supporting base; and the top part of the conveying assembly is slidably connected with the clamping assembly. Through forming a second guide groove and a first guide groove with opposite opening directions, under the pulling force of a clamping air cylinder and under the limiting action of the first guide groove and the secondguide groove, two clamping and adjusting rods slide along the first guide groove at the same time, two clamping heads are folded towards the middle under the action of the first guide groove, the twoclamping heads can clamp a rectangular workpiece and can clamp a cylindrical workpiece, even if the cylindrical workpieces with different diameters are fixed under the joint clamping of the two clamping heads, the circle center can be guaranteed to be always positioned at the same position, the material clamping mechanism does not need to be adjusted for the workpieces with different diameters, and machining of the taper pipe contracting machine is facilitated.

Description

technical field [0001] The invention belongs to the technical field of tapered tube shrinking machines, in particular to a material clamping mechanism of a tapered tube shrinking machine. Background technique [0002] The pipe shrinking machine is to expand and shrink the end face of the pipe fittings under normal conditions. The pipe shrinking is a forming process that reduces the diameter of the end of the pipe blank. In order to improve the firmness and aesthetics of the pipe frame, the end of the steel pipe is usually reduced. , while inserting the end of another steel pipe, so that the steel pipe shrinking machine is used, and the clamping mechanism is needed to clamp and fix the material during the working process of the tapered pipe shrinking machine; [0003] The traditional clamping mechanism of the tapered tube shrinking machine cannot effectively clamp the material during the test process, and clamp and fix the fixed fixture in the form of a bench vise. The cente...

AI Technical Summary

Problems solved by technology

[0003] The traditional clamping mechanism of the tapered tube shrinking machine cannot effectively clamp the material during the test process, and clamp and fix the fixed fixture in the form of a bench vise. The center of the processing mouth of the machine is aligned, so it cannot be applied to workpieces of different shapes. Therefore, it is necessary to design a tapered tube shrinking machine clamping mechanism that can be applied to different structural shapes.
