Flying wire cutting device for transformer coil

Abstract

The invention discloses a fly wire shearing device for a transformer coil. The fly wire shearing device comprises a concentric-square-shaped ceramic seat body. A flange is arranged at the lower end ofthe ceramic seat body, a plurality of concentric-square-shaped grooves are formed in the bottom face of the flange, and sealing rings are fixed in the grooves of the ceramic seat body in an insertedconnection mode; multiple sets of opposite positioning blocks are formed on the opposite inner walls of the ceramic seat body, and inserting grooves are formed in the two side walls of the positioningblocks; a rectangular pipe sleeve is arranged between the opposite positioning blocks on the two sides of the ceramic seat body, [-shaped clamping sleeves are connected to the two ends of the pipe sleeve in an inserted mode, and the two ends of the clamping sleeves are connected into the inserting grooves of the positioning blocks in an inserted mode; a rectangular notch is formed in the upper end face of the pipe sleeve, and a threaded hole is formed in the lower end of the pipe sleeve; and a trapezoidal wedge block is connected into the rectangular notch of the pipe sleeve in an inserted mode, the clamping sleeves abut against the two side walls of the wedge block, and a bolt is connected to the wedge block in an inserted mode and penetrates through the wedge block to be connected intothe threaded hole of the pipe sleeve in a threaded mode. The fly wire shearing device is conveniently mounted and demounted on a transformer shell, the shape of the transformer shell does not need tobe changed, mould opening is not needed, and the cost is saved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of transformers, in particular to a flying wire cutting device for transformer coils. [0003] Background technique: [0004] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. In electrical equipment and wireless circuits, it is often used for raising and lowering voltage, matching impedance, safety isolation, etc. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. In the production process of the transformer, the coil of the transformer has two lead wires extending outward. Due to the needs of processing, the lead wires are usually reserved for a certain length. In the subsequent process of processing, the excess length of the lead wires needs to be cut, that is, In the flying wire process, it is necessary to m...

Problems solved by technology

In the production process of the transformer, the coil of the transformer has two lead wires extending outward. Due to the needs of processing, the lead wires are usually reserved for a certain length. In the subsequent process of processing, the excess length of the lead wires needs to be cut, that is, In the flying wire process, it is necessary to maintain the consistency of the remaining lengths of the two leads during the cutting of the flying wires. The existing process is often cut manually, which has low cutting efficiency and high labor costs, and there are certain errors in manual wire cutting. It is difficult to ensure the consistency of the remaining lead wire length, which affects the use and appearance of the transformer
