Cooling device for stainless steel welding

Abstract

The invention discloses a cooling device for stainless steel welding. The cooling device comprises a cooling box, a stainless steel pipe, an auxiliary cooling device and a drying and draining device. An auxiliary cooling device and a drying and draining device are installed in a cooling box, cooling liquid is injected into the cooling box, the lower end of the auxiliary cooling device is soaked in the cooling liquid, three internal driving mechanisms drive two internal barrels to rotate, a pretreatment barrel scrapes off impurities on the surface of a steel pipe, and a heat conduction barrel conducts heat on the steel pipe rapidly; a shifting sweeping piece in the pretreatment barrel and a heat conduction piece in the heat conduction barrel can take up cooling liquid to make contact with a steel pipe, rapid heat exchange is achieved, the cooling liquid can also be shifted, and the situation that the subsequent cooling effect is affected due to rapid temperature rise of the cooling liquid is avoided; and a heating roller and an air blowing assembly are adopted in the drying and draining device to dry the steel pipe, the position of the heating roller is adjustable, the heating roller can rotate, the steel pipe rotates in the heating process, and water stains on the surface of the steel pipe are rapidly dried in cooperation with high-pressure air.

Description

technical field [0001] The invention relates to the related field of stainless steel welding, in particular to a cooling device for stainless steel welding. Background technique [0002] Stainless steel pipe is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchenware. During the processing of stainless steel pipes, it needs to be welded, and after the welding is completed, it needs to be cooled as a whole, and a special cooling device is required. [0003] In the actual use of the existing stainless steel welded cooling device, there are the following problems:...

AI Technical Summary

Problems solved by technology

[0004] ①The stainless steel tube is directly immersed in the cooling liquid, which will easily cause the cooling liquid to heat up and affect the subsequent cooling efficiency;

[0005] ② During the cooling process, the steel pipe is fixedly placed in the coolant, the cooling efficiency and effect are poor, and the heat exchange efficiency is low;

[0006] ③In the subsequent cooling process, most of the water stains on the surface are naturally drained or dried with a hair dryer, the drying uniformity is poor, and water marks are easy to remain on the surface
