Three-phase transformer parts stamping method

Abstract

The invention provides a three-phase transformer parts stamping method which comprises a discharging mechanism and a stamping mechanism. The stamping mechanism is installed on the discharging mechanism in a sliding fit mode and is located right above the discharging mechanism. The method of the present invention solves the problems that stamping forming is adopted in the current production so as to guarantee the specification uniformity during large-batch production; many problems exist in the E-shaped iron core punching sheet production process at present, for example the fixing effect of silicon steel sheets in the machining process is worse, so that errors on the surfaces of the silicon steel sheets are increased easily in the punching process; and meanwhile, burrs on the surface of thepunching sheets are more, the quality of the surface of the punching sheets is reduced, and the quality of the iron cores directly affects the transmission power of a 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;
