Embodiment Construction

[0013] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0014] like figure 1 , figure 2 As shown, the present invention is a process for online removal of material processing stress and straightening and cutting, including the following steps: unwinding of stainless steel wire rod 1, straightening, heat treatment, cooling, secondary straightening and shearing; The heat treatment adopts the tube furnace 2 for tempering treatment. The length of the tube furnace 2 is 8 meters, the heat treatment temperature is 900° C., and the wire speed of the stainless steel wire rod 1 is 4-5 m / min. The tube furnace 2 has a power of 65KW; the cooling process adopts tube cooling: the heat-treated wire rod passes through the coo...

Abstract

The invention discloses a material processing stress online removing and straightening cutting-off process. The process sequentially comprises the following process steps of stainless steel wire rod unwinding, straightening, heat treatment, cooling, secondary straightening and shearing. Heat treatment adopts a tubular furnace for tempering treatment, the length of the tubular furnace is 8 m, the heat treatment temperature is 900 DEG C, and the wire inlet speed of the stainless steel wire rod is 4-5 m/min. Online machining stress removing can be achieved, the working time is saved, the workingefficiency is improved, cooling is not pure air cooling or water cooling any more, the mode between air cooling and water cooling is adopted, the problem that the air cooling efficiency is not high issolved, and the problem that due to water cooling, the cold hardening degree of materials is too high is solved; the technological mode can be well matched with a continuous mode of online rolling and online heat treatment of stainless steel products, the machining time is short, and the machining efficiency is high.

Description

technical field [0001] The invention relates to a technology for online removal of material processing stress and straightening and cutting. Background technique [0002] During the processing of metal materials, there will inevitably be heat treatment and cooling processes, and processing stress will be generated during processing. At present, the way to remove stress is generally to remove stress after processing semi-finished products. Anti-rolling, not to mention the low efficiency, a certain amount of winding tension will be generated during the winding and anti-rolling process. The patent with the publication number CN208450263U: a straightening and adjusting device for processing stainless steel wire rods, including a base on which a rotating drum is arranged; one end of the rotating drum is extended and connected to a forward and reverse motor; Several straightening discs and cleaning frames are arranged alternately on the rotating cylinder; a sliding sleeve is arra...
