Hairpin permanent magnetic synchronous motor copper wire forming device and process

Abstract

The invention discloses a hairpin permanent magnetic synchronous motor copper wire forming device. The device comprises a bending mechanism used for feeding a copper wire and continuously bending the copper wire on a horizontal plane, a forming die, a copper wire conveying pneumatic claw, a forming die conveying line, a downward pressing air cylinder and a rack. The forming die is used for carrying out extrusion molding on the copper wire bent by the bending mechanism; the copper wire conveying pneumatic claw is used for placing the copper wire bent by the bending mechanism into the forming die; the forming die conveying line is used for supporting the forming die and driving the forming die to reciprocate on the forming die conveying line, the downward pressing air cylinder is used for pressing the forming die to extrude the copper wire, and the downward pressing air cylinder is located above the forming die conveying line; and the rack is used for bearing the bending mechanism, the copper wire conveying pneumatic claw, the forming die conveying line and the downward pressing air cylinder. Bending parameters of the bending mechanism and the forming die can be freely combined and exchanged, the production flexibility is high, the production difficulty of the copper wire is reduced, and the production efficiency of the copper wire is improved.

Description

technical field [0001] The invention belongs to the technical field of forming equipment for copper wires of card-sending motors, and relates to forming equipment for copper wires of card-sending motors and a forming process. Background technique [0002] Hairpin permanent magnet synchronous motors (card generators) are gradually being applied on a large scale in the domestic drive motor market. Compared with traditional wound motors, due to the flat characteristics of Hairpin copper wires, under the same power, the motor volume is smaller and the power Higher is the development direction of the next generation of new energy drive motors. However, due to the complex manufacturing process and the difficulty in product design, there is currently no mature mass production line in the Chinese market. Due to the complex and diverse shapes of flat copper wires, at least two shapes are required for the same layer of copper wires on the electronic stator of the hairpin, which makes...
