The tangential shear of the winding machine according to the present invention, wherein the end of the fixing block protrudes into the groove, and the side surface of the extending portion is fixed to the inner wall of the groove.

The wire cutter tangential shear of the present invention, wherein the wire hook groove groove has a rectangular cross section; the lower end of the fixing block is provided with a bump matching the shape of the wire hook groove groove.

The wire cutter tangential shear of the present invention, wherein the end of the wire arm is provided with a connecting flange connecting the connecting rod.

The wire cutter tangential shear of the present invention, wherein the fixing seat is provided with a through hole corresponding to the connecting rod.

A winding machine tangential method, which is applied to the above-mentioned winding machine tangential shearing, which is implemented as follows, the connecting rod is driven to move downward by the cylinder, and the pulling arm is driven downward, and the line hook hooks the copper wire Then, the cylinder drives the cable arm to ascend, and the wire hook and the lower end surface of the groove of the guide sleeve are pressed to cut the copper wire.

Beneficial effect

The utility model has the beneficial effects that when the tangential line is needed, the connecting rod is driven downward by the cylinder to drive the pulling arm downward, the line hook hooks the copper wire, and the rear cylinder drives the pulling arm upward, and the line hook and the lower end surface of the guiding sleeve are squeezed. The copper wire is cut by pressure, the tangential effect is good, the structure is simple and compact, the cost is low, and the occupied space is small; the guide sleeve is used for guiding, and the pulling arm has good running stability.
