The invention provides a pipe contracting device of a pipe contracting machine, and belongs to the technical field of pipe machining. The pipe contracting device solves the problem that an existing pipe contracting machine is poor in pipe contracting forming effect. The pipe contracting device comprises a striking assembly and a conical hole base, the striking assembly comprises a striking base and a plurality of striking modules arranged on the striking base, a conical hole used for containing the striking assembly is formed in the conical hole base, the striking modules can move back and forth in the radial direction of the conical hole, a plurality of corrugations are arranged on the inner wall of the conical hole, the corrugations are in a strip shape and extend in the axial directionof the conical hole, the corrugations protrude out of the inner wall of the conical hole, and in the process in which the striking base moves in the axial direction of the conical hole relative to theconical hole and rotates relative to the conical hole at the same time, the striking modules can move back and forth in the radial direction of the conical hole relative to the striking base. The pipe contracting device has the advantages that high-frequency uniform annular striking is adopted for pipe contracting, pipe diameter contracting is uniform, and the pipe contracting effect is good.
Description
technical field [0001] The invention belongs to the technical field of pipe fitting processing, and relates to a pipe shrinking machine, in particular to a pipe shrinking device of the pipe shrinking machine. Background technique [0002] The pipe shrinking machine is a kind of equipment widely used in the field of pipe fitting processing. It mainly expands or shrinks the end face of the pipe fitting under normal conditions. The tube blank enters the deformation zone under the action of axial force, and produces tangential shrinkage plastic deformation in the deformation zone. [0003] The pipe shrinking method of the existing pipe shrinking machine generally shrinks the pipe diameter by extruding the outer circumference of the pipe fitting with a briquetting block, and the extrusion molding pipe diameter is not uniform, the effect is not good, and the efficiency is low. Contents of the invention [0004] The purpose of the present invention is to aim at the above-mention...
