[0002] The punch is a part in the mold used to shape the inner surface of the product. Its main function is to shape the inner surface parts of the product. Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness. Therefore, it is widely used in the manufacture of punches. When assembling the punch, a fixing device is required.

[0003] Chinese patent CN208495581U discloses a tungsten steel punch fixing device, including a fixing block, a tungsten steel punch and an electronic level, wherein a mounting plate is installed on the top of the fixing block by bolts, a fixing groove is provided at the bottom of the fixing block, a tungsten steel punch is placed in the fixing groove, mounting grooves are provided at both ends of the fixing block, an electric telescopic rod is installed at the bottom of the mounting groove through a connecting piece, and a pressure sensor is installed on one side of the fixing block through a mounting piece.

[0004] When the above-mentioned fixing device fixes the punch, it moves the punch upward and snaps it into the fixing groove. When the weight of the punch is large, it is very inconvenient to move it upward and snap it into the fixing groove. In addition, due to the lack of a mechanism for fixing the lower part of the punch, when the punch is driven to snap into the fixing groove by moving the press downward, the lower part of the punch cannot be limited. When the press is pressed down, the punch is easily tilted, and the installation position of the punch is easily made inaccurate when the punch is installed. At the same time, the above-mentioned patent uses the rubber wear-resistant pad to play an impact-resistant buffering role during impact, but the impact resistance of the rubber wear-resistant pad is relatively weak. Therefore, a technical measure is proposed to solve the problem of lack of a mechanism for fixing the lower part of the punch, inconvenient installation when the weight of the punch is large, and the lower part of the punch cannot be limited. When the press is pressed down, the punch is easily tilted, and the installation position of the punch is easily made inaccurate when the punch is installed, and the impact resistance of the rubber wear-resistant pad is relatively weak.

[0034] Working principle: When actually installing the tungsten steel punch 8, place the tungsten steel punch 8 at the center of the upper surface of the base 1 by hand, and then start the lower clamping assembly 2 to fix the tungsten steel punch 8. The specific method is to start the second electric telescopic rod 205, and the second electric telescopic rod 205 starts to drive the frame 201 to move upward. When the frame 201 moves to the lower part of the tungsten steel punch 8, start the first electric telescopic rod 202, and the first electric telescopic rod 202 starts to drive the moving plate 403 to slide along the slide groove 204 and approach each other. The moving plates 403 approach each other and drive the clamping teeth 207 to clamp the tungsten steel punch 8, thereby completing the fixation of the lower part of the tungsten steel punch 8.

[0035] Then, the press machine 5 is started to drive the box body 3 to move downward. The box body 3 is fixedly welded at the bottom of the press machine 5. The press machine 5 is started to drive the box body 3 to move downward. When the box body 3 moves downward, the tungsten steel punch 8 is inserted into the circular groove 10. Then, the press machine 5 is closed. At this time, the upper clamping assembly 4 is used to fix the tungsten steel punch 8, and the turntable 401 is rotated. The rotation of the turntable 401 drives the screw 402 to move horizontally along the box body 3 toward the tungsten steel punch 8. The movement of the screw 402 drives the moving plate 403 to slide along the limiting groove 6. The moving plate The movement of 403 pushes the connecting rod 404 to move, and the movement of the connecting rod 404 drives the clamping ring 405 and the anti-slip sleeve 406 to move toward the direction of the tungsten steel punch 8. When the clamping ring 405 clamps the tungsten steel punch 8, the rotation of the turntable 401 is stopped. Through the movable connection between the connecting rod 404 and the clamping ring 405, different tungsten steel punches 8 can be adapted. The anti-slip sleeve 406 clamps the tungsten steel punch 8 more tightly. When installing the tungsten steel punch 8, the fixing of the lower clamping assembly 2 to the tungsten steel punch 8 is released, and the lower clamping assembly 2 is restored to its original position;

[0036] When the surface of the part is actually extruded, the press 5 is started. The press 5 starts and drives the box body 3 to move downward. When the box body 3 moves downward, the tungsten steel punch 8 is driven to move downward. When the tungsten steel punch 8 contacts the part, the tungsten steel punch 8 squeezes the rubber wear-resistant pad 901 upward, and the rubber wear-resistant pad 901 squeezes the bottom plate 902 upward. The bottom plate 902 squeezes the spring 903 upward. The spring 903 removes the upward impact force to avoid the instantaneous impact force when the tungsten steel punch 8 contacts the part and damages the bottom of the tungsten steel punch 8 and the box body 3. Then the tungsten steel punch 8 moves downward to complete the processing of the part.
