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

Abstract

The invention discloses a silicon steel sheet welding water-cooling device and a silicon steel sheet laminating and welding method. The silicon steel sheet welding water-cooling device comprises a laminating tool, a water inlet pipeline and a water outlet pipeline. The laminating tool comprises a bearing part and a stand column on the top of the bearing part. The stand column comprises a cylinderand a plurality of limiting columns evenly distributed on the side wall of the cylinder. A water outlet channel is formed in the top of the cylinder. Water inlet channels are formed in the tops of thelimiting columns. The water inlet channels communicate with the water outlet channel. A traditional silicon steel sheet clamping mechanism is replaced, silicon steel sheets are rapidly laminated, thewelding efficiency of the silicon steel sheets is improved, and the laminating damage of the silicon steel sheets is avoided. By means of the laminating and welding method of the silicon steel sheets, a welding heat source performs welding along a welding trajectory of a weld joint, the welding trajectory is consistent with the flowing direction of water flow, the heat of the weld joint is rapidly cooled and removed, the welding temperature of the silicon steel sheets is rapidly lowered, the silicon steel sheets have no heat transferring effect, the deforming and cracking phenomena cannot becaused, and the welding quality of the silicon steel sheets is improved.

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,...
