Automatic bending and wire wrapping process for copper sheet shielding layer of mutual inductor

Abstract

The invention discloses an automatic bending and wire wrapping process for a copper sheet shielding layer of a mutual inductor, and belongs to the field of mutual inductor processing. The process comprises the following steps of 1, cutting a copper sheet into a specified size; 2, automatically bending the two ends of the copper sheet; 3, placing a lead at the bent position of the copper sheet; 4,flattening the copper sheet on which the lead is placed; 5, moving the copper sheet to a second workpiece conveying assembly through a manipulator; 6, cutting the two ends of the copper sheet; 7, automatically grinding the four corners of the copper sheet; and 8, automatically discharging the copper sheet. The method is ingenious in process design and smooth in procedure connection, the mutual inductor copper sheet shielding layer can be automatically bent and wrapped, the automation degree is high, one person can be responsible for one production line, the productivity is several times that of manual bending and wrapping, the productivity is greatly improved, and the method has remarkable economic value.

Description

technical field [0001] The invention relates to the field of transformer processing, in particular to an automatic bending process of a copper shielding layer of a transformer. 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 lead wire wrapped in the bending part of the copper skin plays the role of grounding or connecting with other components, so as to facilitate the subsequent processing of the transformer and realize automatic production; one person can only bend about 100 pieces per day, and the copper skin is a whole Rolls, first cut into the required size and then processed, the operation is cumbersome, the efficiency is low, time-consuming and laborious, in order to improve the efficiency, it is now necessary to customize an automatic bending and wrapping machine for the copper shielding layer of the transformer to solve the above technical problems
