Device for forming multiple strands of double-turn stator coils

Abstract

The invention discloses a device for forming multiple strands of double-turn stator coils, and solves the problems that an existing fixture for multiple strands of double-turn stator coils is high in discreteness and the quality of wound coils is unlikely to control. The device mainly comprises a forming device fixing frame body and a movable bent handle (18), wherein winding wires of the multiple strands of double-turn stator coils to be wound (17) are wound along a coil winding rail on the forming device fixing frame body; a sleeve (20) on the bent handle (18) movably sleeves a corresponding vertical column at positions to be bent and cranked of the coils, and the pre-bent winding wires are clamped between a bending vertical column (21) on the bent handle (18) and the corresponding vertical column; the bent handle (18) is rotated in the pre-bending direction; the bending vertical column (21) bends the winding wires by taking the corresponding vertical column as a supporting point. The whole forming device fixing frame body is fixed on a base beam (19). The device disclosed by the invention guarantees the consistency of the size, the angle and the radian of the coil.

Description

technical field [0001] The invention relates to a forming tool for a motor coil, in particular to a forming tool for a multi-strand double-turn stator coil. Background technique [0002] With the emergence of coil manufacturing equipment such as CNC shuttle winding machines and CNC expanding machines, this field has gradually become familiar with and accumulated certain experience in the manufacture of multi-turn frame-formed coils. However, there has been no breakthrough in manufacturing equipment for multi-strand double-turn stator open-formed coils because of its long design and manufacturing cycle and high cost. In the prior art, the traditional stator coil knocking device is still used to complete the multi-strand double-turn stator coil. This device has the defects of large process dispersion and difficult control of the quality of the wound coil.
