Bright yarn straightening process

Abstract

The invention discloses a bright wire straightening process, and relates to the technical field of metal processing equipment. A bright wire straightening process comprises the steps that firstly, a raw material metal wire with the polished surface is wound on a winch through the winch to replace a machining wire to be circularly wound, and after winding is completed, a wire head is arranged out; step 2, enabling a to-be-processed wire drawing head to pass through a peeling die, reducing the diameter of a to-be-processed wire by utilizing the peeling die, and linearly transmitting the to-be-processed wire to next processing equipment through a wire guide wheel; and 3, the to-be-drawn wire subjected to primary scalping passes through the interior of the high-temperature vacuum furnace in a linear mode, the temperature in the high-temperature vacuum furnace is controlled within a certain range, and the passing time is controlled. According to the method, the silk threads are subjected to high-temperature treatment through the high-temperature vacuum furnace after passing through the peeling mold, annealing operation is conducted through the heat preservation chamber, the residual stress of the silk threads can be reduced, the diameter size of the silk threads is stabilized, the silk thread deformation and cracking tendency is reduced, and the silk threads have higher plasticity.

Description

technical field [0001] The invention relates to the technical field of metal processing equipment, in particular to a bright wire straightening process. Background technique [0002] The bright wire has very high requirements on the surface finish of the bright wire. The smooth surface of the bright wire can ensure the smoothness of the subsequent coating steps. Therefore, the wire for making the bright wire must undergo two or more wire drawing treatments. [0003] In the traditional wire drawing process, after the raw material wire is peeled, it will not be subjected to metal processing operations, and a certain internal stress will be generated inside the peeled wire, which will affect its performance. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a bright wire straightening process to solve the problems raised in the above-mentioned background art. [0005] In order to achieve the above object, the present invention provides the ...
