Abstract

A square coil winding machine relates to the coil winding technical field, and aims to solve the problems that the manual shaping is needed for the bad winding of the square coil, carried out by the existing winding machine, and the increased electrical loss of the copper wire due to the crystal lattice variation of the cooper wire, caused by the external force impact during the winding, and the roughness of the coil along the generating line direction, caused by the cracking of the paper of the paper wrapped wire at the corner of the coil. The left side end head of a first lever (3) is vertically connected with the middle external surface of a shaft (4). One end of the shaft (4) is rotationally connected with a shaft hole of a first bracket (1-3) on the upper end of a host computer (1). The middle of the other side of the shaft (4) is rotationally connected with a shaft hole of a second bracket (1-4) on the host computer (1). A hole (5-5) on one side of a second lever (5) is connected with the other end (4-1) of the shaft (4). No manual shaping is needed and the standard square coil can be winded by utility model.

The making of existing square coil is that mould is fixed on the coil winding machine, when coil winding machine rotates, copper cash is made coil on mould, four corners and square coil has whenever turned around, every corner all must stop operating, strike line with wooden mallet again line is leaned against on the mould, said method has following shortcoming:

1, coiling efficient is low, and the coil molding of coiling is bad and approximate ellipsoidal must lean on artificial shaping.

2, striking in the line process with wooden mallet, copper cash is subjected to intense impact, and the lattice of copper cash changes, and the copper cash electrical loss is increased.

3, the paper of the paper covered wire of coil corner ftractures easily, and reduces the dielectric strength of transformer.

4, because can there be the not problem of constant character in operating personnel's hand strength, cause the coil of coiling uneven, when transformer is subjected to external impacts, crack brokenly insulating paper easily between the teeth and cause turn-to-turn short circuit and burn transformer along generatrix direction.
