Embodiment Construction

[0016] The operating process of the present invention is as follows:

[0017] 1. External processing of wool is cutting and deburring. The purpose is to cut large silicon steel strips into standard materials that meet the corresponding specifications for winding iron cores. (1) The width of the fixed hob must meet the requirements of the corresponding standard material. Load the large material into the shearing machine. After turning on the power, start the knife and try to cut 1 meter to measure whether it meets the requirements. (2) Continuous cutting is carried out after the trial cutting meets the requirements. During this process, it should be observed whether the silicon steel strip is flat and not broken, the straightness of the trimmed edge within the first meter should not be greater than 0.05mm, and the surface of the strip is free of oil. (3) The cut silicon steel strip should meet the requirements of the corresponding size regulations. The silicon steel strip has ...

Abstract

The invention relates to the technology of power transformer, pulse transformer, magnetic amplifier and converter, in particular to a processing method for silicon steel ribbon iron core of direct current electric transmission and transformation radio-frequency reactor. According to the technical scheme provided by the invention, the processing method for the silicon steel ribbon iron core of direct current electric transmission and transformation radio-frequency reactor includes the following steps: a, winding, namely the silicon steel ribbon is wound into an iron core; b, heat treatment, namely the iron core primary product is annealed under vacuum; c, dipping paint, namely vacuum dipping paint is carried out on the iron core semifinished product; d, cutting, namely the iron core semifinished product after dipping paint is loaded into a cutting clamp of a cutting machine in a lying way, the cutting machine is started to begin cutting with the cutting speed of 200-300 r/min. The invention can improve the quality of product.

Description

technical field [0001] The invention relates to a production technology of a power transformer, a pulse transformer, a magnetic amplifier and a converter, in particular to a processing method of a silicon steel thin-strip iron core of a DC power transmission and transformation high-frequency reactor. Background technique [0002] The specifications of traditional silicon steel sheets are generally 0.1mm, 0.2mm, 0.23mm, 0.27mm, etc. This kind of silicon steel sheet is mainly suitable for ordinary iron cores. The traditional silicon steel sheet processing technology cannot be used for the processing of the thin strip core. If the traditional operation process is used to process the thin strip core, the finished product may not necessarily have the characteristics of high magnetic induction, high power, and good environmental adaptability. Contents of the invention [0003] The object of the present invention is to design a processing method for silicon steel strip iron core ...
