Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of motors and relates to a rotor, in particular to a novel rotor punching sheet. Background Art
[0002] The motor rotor punching is a stamping part installed on the motor rotor, usually made of high-speed steel or hard alloy. Its main function is to make the motor rotor generate a magnetic field when running, and drive the motor to run through the magnetic force.
[0003] The common rotor punchings on the market increase heat dissipation efficiency and reduce weight by opening through holes in the punching sheets. Therefore, holes need to be punched on the punching sheets, but the punched material is basically waste, resulting in material waste. Summary of the invention
[0004] The utility model aims to provide a new rotor punching sheet with high efficiency in heat dissipation and low loss in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a new type of rotor punching, characterized in that it includes a punching body, a plurality of protrusions are evenly distributed in an annular shape on the punching body, a winding groove is provided between the protrusions, and a wire storage groove is provided at the bottom of the winding groove, a plurality of heat dissipation holes are provided in the protrusions, and a spoiler is provided in the heat dissipation hole, one end of the spoiler is connected to the punching body, and the spoiler is inclined to the punching body.
[0006] In the above-mentioned novel rotor punching sheet, a plurality of through holes are evenly distributed in an annular shape on the punching sheet body, support blocks are vertically arranged in the through holes, and both sides of the support blocks are provided with centrally symmetrical clamping grooves.
[0007] In the above-mentioned novel rotor punching sheet, torsion portions are provided on both sides of the support block.
[0008] In the above-mentioned novel rotor punching sheet, a main shaft hole is provided at the center of the punching sheet body, and a spline groove is provided on the main shaft hole.
[0009] Compared with the prior art, the new rotor punching piece converts the correction that should be cut off into spoilers and support blocks, thereby increasing the heat dissipation efficiency and support rigidity without adding components. Several spoilers are stacked and arranged so that the punching piece can generate air convection when rotating, thereby increasing the heat dissipation efficiency, thereby increasing the efficiency of the rotor operation and reducing material loss. The torsion portion makes it easier to twist the support block after punching, and the upper and lower docking is carried out through the centrally symmetrical clamping groove to increase the support rigidity of the punching piece.

During processing, the spoiler is formed by punching, and then the spoiler 8 is bent by a bending machine. Multiple punching bodies 2 are stacked and arranged. Due to the thickness limitation of the punching sheets, the multiple punching bodies 2 are arranged in a spiral array, and multiple spoilers 8 are arranged in a spiral shape. When rotating, the air is disturbed to form an airflow, thereby increasing the heat dissipation efficiency.
[0015] Preferably, a plurality of through holes 7 are evenly distributed in a ring on the punch body 2, a support block 12 is vertically arranged in the through hole 7, and both sides of the support block 12 are provided with a centrally symmetrical clamping groove 11. During production, the support block 12 is formed by punching, and then the support block 12 is rotated by a bending machine, and finally the clamping groove 11 is extruded by an extruder. The punch bodies 2 are stacked up and down, and their clamping grooves 11 and the support blocks 12 are in conflict with each other, thereby increasing the support rigidity.
[0016] Preferably, torsion portions 10 are provided on both sides of the support block 12 .
[0017] Preferably, a main shaft hole 3 is provided at the center of the punch body 2 , and a spline groove 1 is provided on the main shaft hole 3 .
[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
