A stamping processing method for three-phase transformer spare parts

Abstract

The invention provides a stamping processing method for three-phase transformer spare parts, which includes a discharge mechanism and a punching mechanism. The punching mechanism is installed on the discharge mechanism through a sliding fit. Right above the mechanism; the present invention solves the problem that stamping is used in production today to ensure the uniformity of specifications during mass production. At present, there are many problems in the production process of E-type iron core punching, such as silicon steel sheet in the process of processing The fixing effect of the steel sheet is poor, which will easily lead to an increase in the error of the silicon steel sheet surface during the stamping process. At the same time, there are more burrs on the surface of the punched sheet, which reduces the quality of the punched sheet surface. The quality of the iron core directly affects the transmission power of the transformer.

Description

technical field [0001] The invention relates to the technical field of stamping of transformer spare parts, in particular to a stamping processing method of three-phase transformer spare parts. Background technique [0002] Transformer refers to a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core; iron core is an indispensable core component that constitutes the magnetic circuit of a power transformer. It is the main magnetic component of the transformer. The road part is usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and insulating paint on the surface. The quality of the iron core directly affects the transmission power of the transformer. The E-type iron core is commonly used in transformers. Its main advantage is that the primary and secondary of the winding can share a skeleton, which has a high window space factor, and the iron co...

Problems solved by technology

[0003] Stamping is used in production to ensure the uniformity of specifications during mass production. At present, there are many problems in the production process of E-type iron core punching. For example, the fixing effect of silicon steel sheet is poor during processing, which may easily lead to The error on the surface of the silicon steel sheet increases, and at the same time, there are more burrs on the surface of the punched sheet, which reduces the quality of the punched sheet surface, and the quality of the iron core directly affects the transmission power of the transformer;
