Round link chain single link stretching machine

Abstract

The invention relates to the field of structural design of machine tools for the single-ring correction of a circular ring chain repairing and connecting process, in particular to a circular ring chain single-ring stretcher which is used for correcting geometric dimensions of a repaired and connected chain ring and performing certain pre-stretching after a chain is repaired and connected. For many years, due to the fact that waste products which are generated after a heat treatment process of the chain cannot be subjected to single-ring correction, the repaired and connected chain ring cannot meet the requirements of the process on the geometric dimensions and the properties, waste rings are cut by gas, and the cut chain is treated as a short bar, so that the production cost is improved. The circular ring chain single-ring stretcher is composed of two sets of wheel passing devices, two sets of chain conveying devices, a machine body, a movable clamp device, a stationary chuck body, a protecting device, a hydraulic pump station and a KPH150 electrical appliance control system, wherein each wheel passing device is mounted at the upper part of the corresponding end of the machine body; the chain conveying devices are positioned on the left and right sides of the machine body and are mounted at the top ends of a left chain wheel bracket and a right chain wheel bracket respectively; the machine body is a main body connected with all parts. According to the circular ring chain single-ring stretcher, the problem that single-ring correction cannot be performed in the prior art is solved fundamentally.

Description

technical field [0001] The invention relates to the structural design field of machine tools used for single-ring calibration in the repairing process of circular link chains, in particular to a circular-link chain single-ring stretching machine, which is used to check the geometric dimensions of the repaired link after the chain is repaired. Correction and some pre-stretching. [0002] technical background [0003] Over the years, we have adopted the method of repairing, if there are welding waste and weaving waste links found in the welding and previous processes, use gas cutting to cut them off, and then use a single link to separate the two chains with a single link. The patching machine is connected, and then the production of the next process is carried out. However, waste products appear after heat treatment and stretching. Since the single-link correction cannot be performed, the repaired link cannot meet the geometric dimensions and performance requirements required...

AI Technical Summary

Problems solved by technology

However, waste products appear after heat treatment and stretching. Since the single-link correction cannot be performed, the repaired link cannot meet the geometric dimensions and performance requirements required by the process, so it will have a great impact on the three performance indicators of the chain. The test elongation rate of the chain is affected, and the three performance indicators of the chain are unqualified. In this way, the waste ring can only be cut off, and the cut chain should be processed in short lengths according to the customer's needs. In this way, it is necessary to cut off multiple qualified ones. chain link, which increases production costs
