Automatic bending and wire-wrapping machine for mutual inductor copper sheet

Abstract

The invention discloses an automatic bending and wire-wrapping machine for a mutual inductor copper sheet, and belongs to the technical field of mutual inductors. The machine comprises a forming device, a switching device, a pressing device, a clamping device, a conveying device, a cutting device, a trimming device and a polishing device. The switching device is arranged at the top of the formingdevice and is fixedly connected with the forming device; and the pressing device is arranged at the bottom of the switching device, the conveying device is arranged on the side wall of the forming device, the clamping device is arranged on the side wall of the forming device, the cutting device is arranged at the top of the forming device and fixedly connected with the forming device, and the trimming device and the polishing device are symmetrically arranged at the top of the forming device. By means of the forming device, the trimming device and the polishing device, technical problems thatthe efficiency is low when the copper sheet is bent purely manually, the trimming angle of the copper sheet is inconsistent when the copper sheet is bent manually, and time consumed when the trimmed copper sheet is ground manually is large are solved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an automatic bending and wrapping machine for copper skin of transformers. Background technique [0002] Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can change high voltage into low voltage and high current into small current for measurement or protection system. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate the high-voltage system to ensure the safety of people and equipment. The copper skin of the transformer has two functions: 1. Internally: uniform electric field...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic bending and enveloping machine for the copper skin of a transformer, so as to solve the problem of low efficiency of bending the copper skin by hand in the prior art and the inconsistency of the angle and size of the copper skin to be manually bent and trimmed. It takes a lot of time and technical problems to polish the trimmed copper skin manually
