Description

Technical Field

[0001] The invention relates to the technical field of motor carbon brush processing, in particular to a molding device and method for motor carbon brush processing. Background Art

[0002] The motor carbon brush is an important component in the motor. Its main function is to contact the rotating motor rotor, transfer electrical energy and realize the rotation of the motor rotor. The carbon brush generates friction by contacting and rubbing with the motor rotor, thereby converting electrical energy into mechanical energy and driving the motor to operate normally. When using the motor carbon brush, it is necessary to ensure that the carbon brush is in close contact with the rotor and maintain appropriate friction. At the same time, it is necessary to prevent the carbon brush from aging, wear or breakage. In order to ensure the normal operation of the motor carbon brush, it is usually necessary to regularly check and replace the carbon brush. When processing the motor carbon brush, the carbon brush powder is generally placed in the die, and the punch is pressed into the die under the action of the hydraulic press, thereby forming the carbon brush powder in the die.

[0003] Most of the motor carbon brushes in the prior art are operated in one process during the processing and forming process, and the next process is carried out after the operation is completed. For example, when the applicant applied for the present invention, after searching, he found that a Chinese patent disclosed a "molding device for motor carbon brush processing", and its application number is "202323604423.8". This patent mainly uses a reciprocating knocking piece to reciprocate on the lower mold base to accelerate the shaking of the lower mold base, so that the carbon brush powder is more evenly dispersed in the groove, which helps to improve the quality stability of the carbon brush finished product. However, for the processes such as demolding and polishing required after molding, it is impossible to integrate an integrated structure to reduce the occupied space and reduce the cost. Therefore, according to the applicant's invention, a method is invented to solve the problem of inconvenient demolding of carbon brush powder after molding. Summary of the invention
