AI Technical Summary

Technical Problem

The copper coil rebounds after the shaping is not obvious, which leads to problems that gradually appear after the rotor and end cap are installed. In severe cases, it will cause problems such as vibration of the rotor and uneven speed during the motor operation.

Method used

A shaping device for motors is designed, which includes a shaping workbench, an output mechanism suspended above the shaping area, and a rotating plate that automatically recognizes the position and shapes the coil in a rolling posture. The contact, positioning plate, rotating plate and inclined push plate are driven down through a multi-section hydraulic telescopic rod, and the arc-shaped convex mechanism and spring are used to achieve rolling shaping from the inside to the outside.

Benefits of technology

Through gentle and continuous rolling force, the internal tension of the coil after hard extrusion is effectively released, reducing the rebound after shaping, improving the tightness of the coil on the winding, and releasing the winding through the naturally hanging outer end. margin to improve the operating stability of the motor.

Abstract

The invention discloses a shaping device for a motor and a control method thereof, and relates to the technical field of motor shaping, the shaping effect on a coil is rolling acting force from a spiral inner end to a spiral outer end, on one hand, the rolling acting force is soft and can be continuously generated, and the good metal deformation adaptability is achieved for the coil; on the other hand, the inner end head of the coil is locked, the twisting force of the coil can be released from the naturally drooping outer end of the coil when the coil is pushed and pressed along the spiral direction of the coil, and the twisting force of the coil can be greatly reduced at the moment when the pressure is relieved, so that the tension accumulated in the coil when the coil is subjected to rigid extrusion can be effectively released; the method has the advantages that the inner end of the coil is locked, the outer end of the coil naturally droops, the winding compactness of the coil on the winding can be improved through the rolling type shaping effect progressive from inside to outside, and the winding allowance generated in the outward progressive process can also be released through the naturally drooping outer end of the coil.
