[0002] Stamping dies are common processing equipment in factories. They mainly use a die installed on a press to apply pressure to the material, causing the material to separate or plastically deform, thereby obtaining a desired part. However, the existing stamping dies still have the following problems when in use: When in use, some of the existing stamping dies are still semi-automatic, and the stamping mechanism needs to be manually driven to stamp the die, which is time-consuming and laborious. Therefore, a die stamping mechanism is proposed. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0005] Preferably, a rotation-stopping guide plate is laterally arranged at the outer bottom end of the nut bearing seat, and the screw rod passes through the rotation-stopping guide plate, and the screw rod moves up and down at the middle position of the rotation-stopping guide plate.

[0006] Preferably, a tapered roller bearing is arranged between the nut bearing seat and the screw nut sleeve, and the tapered roller bearing is laterally located at the bottom end of the nut bearing seat, and the screw nut sleeve rotates at the middle position of the tapered roller bearing.

[0007] Preferably, a screw nut is provided at the connection between the screw rod and the screw nut sleeve, and the screw nut is located inside the screw nut sleeve, the screw rod passes through the screw nut, and the screw rod and the screw nut are connected.

[0008] Preferably, a synchronous belt is provided between the servo motor and the screw nut sleeve, and two ends of the synchronous belt are drivingly connected to the servo motor and the screw nut sleeve respectively.

[0009] Preferably, a large pulley is provided between the synchronous belt and the screw nut sleeve, and the large pulley is located laterally at the top of the screw nut sleeve, and the screw passes through the large pulley, the large pulley is transmission connected to the synchronous belt, and the large pulley and the screw nut sleeve rotate synchronously.

[0010] Preferably, a small pulley is provided between the synchronous belt and the servo motor, and the small pulley is located at the bottom end of the servo motor. The servo motor and the small pulley are drive-connected, and the small pulley and the synchronous belt are transmission-connected. When the servo motor drives the small pulley to rotate, it drives the synchronous belt to transmit.

[0011] Preferably, a stamping rod fixing plate is arranged between the screw rod and the stamping rod, and the stamping rod fixing plate is located at the top end of the stamping rod, the stamping rod is vertically fixed inside the stamping rod fixing plate, and the stamping rod fixing plate and the stamping rod have the same movement direction, a stamping rod connecting plate is laterally arranged at the top end of the stamping rod fixing plate, and the stamping rod connecting plate is connected to the screw rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the servo motor drives the small pulley to rotate, and the synchronous belt drives the large pulley to rotate, thereby driving the screw nut to rotate through the screw nut sleeve. Due to the effect of the anti-rotation fixing plate, the screw cannot rotate, and the screw nut sleeve is rotated to realize the linear movement of the screw up and down. When the screw moves downward, it pushes the punch rod to move downward, and the punch rod presses downward on the upper die, so that the upper die moves downward to punch the material and completes the punching action; after the punching is completed, the servo motor rotates in the opposite direction, driving the screw nut to rotate in the opposite direction, so that the screw moves upward and drives the punch rod to leave the upper die. After the upper die loses the downward pressure, it returns to the initial position under the action of the spring force, and the punching forming is completed. Then, the punching protection sleeve is tightly pressed on the punching rod through the punching protection sheet, so that when the punching force of the punching rod exceeds the preset load, the shear force generated between the punching protection sleeve and the punching rod shears the punching protection sheet, so that within the limited stroke of the screw rod, the pressure of the punching rod on the upper die no longer increases, thereby ensuring that the mechanism will not cause overload damage.
