Roundness correction device for circular tube and continuous extrusion winding and unwinding system for circular tube

Abstract

The invention discloses a round pipe roundness correction device which comprises a support, a swing rod, a round pipe correction assembly and a balance assembly, the round pipe correction assembly is located at the feeding end of a take-up machine and can conduct roundness correction on a round pipe to be wound, and meanwhile the balance assembly can balance the acting force of the wound round pipe on the take-up machine on the swing rod. The circular pipe guided out of the circular pipe correction assembly is always tangent to a reel of the take-up machine, and the circular pipe subjected to roundness correction is effectively prevented from bending and deforming again. The device has roundness correction and anti-bending functions, solves the problems that the roundness of the round aluminum pipe becomes poor and the dimensional precision is reduced due to multi-pass bending deformation in the vertical direction after the round aluminum pipe is extruded and before the round aluminum pipe is wound, is beneficial to realizing continuous extrusion winding displacement of the high-precision round pipe, and is suitable for quality control of the refrigeration round aluminum pipe. The circular tube continuous extrusion take-up and winding displacement system comprises circular tube forming equipment, a take-up machine and the circular tube roundness correction device.

Description

technical field [0001] The invention relates to the field of equipment manufacturing, in particular to a circular tube roundness correction device and a circular tube continuous extrusion and winding system. Background technique [0002] The principle of continuous extrusion of round aluminum tube is as follows figure 1 As shown, after the aluminum rod 11 is pressed by the compaction wheel 12, it is embedded in the wheel groove 14, and rotates together with the extrusion wheel 15 under the action of friction. There is an arc surface on the cavity 13 and the outer circumference of the extrusion wheel. Driven by the extrusion wheel, the aluminum rod 11 is sent into the cavity 13, and divided into several strands in the mold, and then re-welded under high temperature and high pressure to form a round aluminum tube 16, which is extruded. After cooling and drying, after passing through the buffer swing arm 17 and the guide device 18, it is wound up by the wire take-up machine 19...

Problems solved by technology

[0004] The object of the present invention is to provide a circular tube roundness correction device and a circular tube continuous extrusion winding and arranging system to solve the problem in the above-mentioned prior art that the round aluminum tube has to pass through multiple passes after being extruded and before being rolled up. The bending deformation in the vertical direction leads to the deterioration of the roundness of the round aluminum tube and the decrease of the dimensional accuracy
