Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire drawing machines, in particular to a tension regulating device. Background Art
[0002] The wire drawing machine is also called a wire drawing machine. It is a pre-processing equipment for the production of standard parts and other metal products. Its purpose is to draw the wire or rod produced by the steel manufacturer and transported to the standard parts and other metal product manufacturers through the wire drawing machine, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wire or rod can meet the raw material processing requirements for the production of standard parts and other metal products. However, in the process of wire drawing, the wire drawing die will be gradually damaged, and the elongation rate of the wire will also change accordingly. If the wire drawing speed is kept unchanged, the tension of the wire will become larger and larger until it breaks. Therefore, it is necessary to adjust the tension of the wire drawing machine regularly. The tension adjustment device of the existing wire drawing machine is generally manually adjusted, which is troublesome to adjust, time-consuming and labor-intensive, and the wire is easy to break during adjustment.
