Automatic bending and wire wrapping machine for copper sheet shielding layer of instrument transformer

Abstract

The invention discloses an automatic bending and wire wrapping machine for a copper sheet shielding layer of an instrument transformer, and belongs to the technical field of instrument transformer machining. The automatic bending and wire wrapping machine comprises a platform, and a traction assembly, a conveying assembly, a portal frame and a grinding assembly which are sequentially arranged on the platform in the length direction of the platform, and a pressing assembly, a cutting assembly and two feeding assemblies are arranged on the inner wall of the portal frame. By means of the automatic bending and wire wrapping machine, coiled copper sheets can be automatically cut into copper sheets of the needed size, then the copper sheets can be conveyed, automatic bending is conducted according to the length directions of the two sides of the copper sheets, leads are automatically placed on the bent parts, the bent parts are flattened, and then a series of operations of cutting, grindingand automatic discharging are conducted on the four sides of the copper sheets, so that automatic bending and wire wrapping of the copper sheet shielding layer of the instrument transformer are achieved, the automation degree is high, one person can be responsible for one production line, the productivity is several times that of manual bending and wire wrapping, the productivity is greatly improved, and remarkable economic value is achieved.

Description

technical field [0001] The invention relates to the technical field of transformer processing, in particular to an automatic bending and wrapping machine for copper skin shielding 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. [0003] The existing transformers all use epoxy resin to directly cont...
