A kind of silicon steel sheet welding water cooling device and silicon steel sheet lamination welding method

Abstract

The invention discloses a silicon steel sheet welding water cooling device and a silicon steel sheet lamination welding method. The silicon steel sheet welding water cooling device includes a lamination tooling, a water inlet pipeline and a water outlet pipeline, and the lamination tooling includes a bearing part and is arranged on the bearing part. The column on the top, the column has a column and a plurality of limit columns evenly arranged on the side wall of the column, the top of the column is provided with a water outlet channel, the top of the limit column is provided with a water inlet channel, and the water inlet channel is connected with the water outlet channel, replacing the traditional The silicon steel sheet clamping mechanism makes the silicon steel sheet stacking fast, improves the welding efficiency of the silicon steel sheet, and avoids the damage of the silicon steel sheet lamination. The silicon steel sheet lamination welding method makes the welding heat source follow the welding track of the weld seam Welding, and the welding track is consistent with the flow direction of the water flow, the heat of the weld is quickly cooled and eliminated, so that the temperature of the weld bead of the silicon steel sheet is rapidly reduced, the silicon steel sheet does not have heat transfer effect, and does not cause deformation and cracking, and improves the silicon steel sheet. welding quality.

Description

technical field [0001] The invention relates to the technical field of silicon steel sheet welding, in particular to a silicon steel sheet welding water cooling device and a silicon steel sheet lamination welding method. Background technique [0002] Silicon steel is indispensable for the manufacture of electromechanical equipment such as motors and transformers. The output of silicon steel sheets is directly proportional to the increase in national power generation. At present, the output of silicon steel in major industrial countries in the world is about 2% of the total output of steel. [0003] At present, the stacked silicon steel sheet core mostly adopts micro-arc plasma welding robot to weld the silicon steel sheet, and adopts the air cooling method to cool the silicon steel sheet. Since the weld seam of the silicon steel sheet cannot be cooled rapidly during the welding process, the heat of the weld seam It is transmitted to the periphery of the silicon steel sheet,...

Problems solved by technology

[0003] At present, the stacked silicon steel sheet core mostly adopts micro-arc plasma welding robot to weld the silicon steel sheet, and adopts the air cooling method to cool the silicon steel sheet. Since the weld seam of the silicon steel sheet cannot be cooled rapidly during the welding process, the heat of the weld seam It is transmitted to the periphery of the silicon steel sheet, causing the silicon steel sheet to have a large deformation after welding, and even cracks, and before welding the silicon steel sheet, it is necessary to perform a series of clamping and stacking of multiple silicon steel sheets through the clamping mechanism. In order to align the welding seams of multiple silicon steel sheets one by one, and stack and clamp the silicon steel sheets, the whole process is complicated to operate, and because the thickness of the silicon steel sheets is very small, it is easy to cause the silicon steel sheets to crack during the clamping process. damage
