New energy motor copper wire three-step forming equipment and three-step forming process

Abstract

The invention discloses a new energy motor copper wire three-step forming equipment comprising a rack, a forming mold and a driving device are arranged at the lower end of the rack, the driving device comprises a first driving set, a second driving set and a third driving set, and the forming mold comprises a first movable mold set, a second movable mold set and a third movable mold set; the first driving set drives the first movable module to bend the middle of a new energy motor copper wire backwards, the second driving set drives the second movable module to bend the middle of the new energy motor copper wire upwards, and the third driving set drives the third movable module to bend the two sides of the new energy motor copper wire downwards. According to the three-step forming equipment and the three-step forming process for the new energy motor copper wire, the new energy motor copper wire is firstly bent from the middle and then bent towards the two sides, the process is simple and convenient, forming can be achieved only through three steps, the machining speed is high, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of forming copper wires of new energy motors, and in particular relates to a three-step forming equipment and a three-step forming process for copper wires of new energy motors. Background technique [0002] In the production process of the motors used in new energy vehicles, the stators and rotors of the motors are produced separately, and then assembled to form a complete motor. The winding of the stator of the traditional motor is to wind the copper wire of the new energy motor in the stator slot, and for the high-power motor used in the new energy vehicle, etc., the copper wire of the new energy motor is generally cut and reshaped into a U-shaped connecting wire. Then insert the U-shaped connecting wires into the stator slots respectively, and finally weld the joints of the U-shaped connecting wires respectively by a welding machine to form a complete stator winding. The production of the U-shaped conne...

AI Technical Summary

Problems solved by technology

The production of the U-shaped connecting wire is to unwind a continuous new energy motor copper wire from the new energy motor copper wire reel, and then cut and extrude it into the corresponding shape. However, the existing equipment first The copper wire of the new energy motor is first bent from both sides, and then bent from the middle. However, due to deformation and stretching during the bending process, the bending position of the copper wire of the new energy motor changes on both sides, which affects the copper wire of the new energy motor. usage of
