Description

Technical Field

[0001] The utility model relates to the technical field of motor punching sheets, in particular to a punching device for producing motor punching sheets. Background Art

[0002] The stamping device for motor lamination production is a metal processing equipment specially used for manufacturing motor laminations. Its core function is to use pressure to cause plastic deformation of metal sheets, thereby achieving precise processing of motor laminations.

[0003] According to the Chinese patent CN202121314195.9, in the application, the punching circular plate together with the punching sheet can be lifted to the top of the circular sleeve by the cooperation of the hollow column and the connecting seat, and the punching circular plate can be tilted by the action of the cylinder and the joint block, so that the stamped silicon steel sheet automatically falls into the receiving box after stamping, thereby completing a relatively automatic material taking work without manual material taking, which reduces the danger on the one hand and facilitates the removal of slag on the other hand, and is more convenient;

[0004] Although the combination of the hollow column and the connecting seat in the application can effectively deal with the dangerous problem of manual material removal, when in use, the friction between the material to be punched and the punching plate is usually insufficient, and the punched sheet may be affected by external forces during the punching process and shift or deform. For this reason, we propose a punching device for the production of motor punching sheets. Utility Model Content

[0020] 1. The stamping device for the production of motor punching sheets is provided with an anti-runaway structure. When the servo motor drives the hydraulic rod to move downward during operation, the connecting plate and the extrusion block will also move downward. In this process, the extrusion block is connected to the auxiliary block through the auxiliary rod and the first spring, and drives the auxiliary block to approach the block to be punched, thereby causing the anti-runaway pressure block to move downward and press the block to be punched to avoid displacement during the punching process, which causes the stamped motor punching sheet to be deformed.

During operation, when the stamping protrusion applies pressure to the block to be stamped during the stamping process, the generated reaction force will be transmitted to the adjusting block, thereby compressing the second spring.

The elasticity of the spring can alleviate these pressures and vibrations, reduce damage such as cracks and deformation caused by stress concentration, protect the integrity of the stamping device and the die, and greatly improve the quality of the motor punching sheets.

The top of the second spring 18 is fixedly connected with the adjustment block 17. The outer side of the adjustment block 17 is movably connected to the inner wall of the recessed block 16. During the stamping process, when the stamping protrusion 9 applies pressure to the block 1 to be stamped, the generated reaction force will be transmitted to the adjustment block 17, thereby compressing the second spring 18. Through the buffering effect of the second spring 18, the damage to the block 1 to be stamped caused by stress concentration can be reduced, thereby protecting the integrity of the stamping device and the mold.
