[0032] The working principle of this utility model:

[0033] refer to Figure 1 When the stamping material is a horizontal plate, place the material between the four positioning plates 3, and simultaneously rotate the universal ball 7 so that the universal ball 7 drives the pressure block 11 to be located outside the positioning plates 3, thereby preventing the stamping head 2 from being obstructed during the stamping process. After the material is placed, refer to... Figure 3 The electric telescopic rod 20 is shortened, at which point it engages with the drive shaft 18. Subsequently, the drive motor 19 drives the bidirectional threaded rod 5 to rotate via the drive shaft 18. (Refer to...) Figure 4 When the bidirectional threaded rod 5 rotates, the slide rod 6 threaded on the bidirectional threaded rod 5 moves in the moving groove 4, thereby bringing the four positioning plates 3 closer to each other. During the process of the four positioning plates 3 getting closer to each other, the four corners of the material can be effectively positioned and clamped, thereby maintaining the stability of the material during stamping. Then the multi-axis traveler drives the stamping head 2 to move, thereby completing the material stamping.

[0034] refer to Figure 1When the punched material is arc-shaped, the jacking plate 13 needs to be jacked up to form a protrusion on the inner side of the die table 1, and the specific operation is as follows, referring to Figure 3 , the electric telescopic rod 20 is driven to extend, at this time, the electric telescopic rod 20 is in clamping engagement with the gear box 17, then the motor 19 drives the gear box 17 to work through the electric telescopic rod 20, and the gear box 17 drives Figure 2 , the rotating sleeve 14 rotates, the second lead screw 15 is driven by the rotating sleeve 14 to move upward guided by the limiting frame 16, thereby pushing the jacking plate 13 to jack up, then referring to Figure 4 , the universal ball 7 is rotated, the pressing block 11 is located on the material side, then the first lead screw 9 is rotated by rotating the handle 12, the first lead screw 9 pushes the pressing block 11 to contact with the material, so as to realize the fixation between the pressing block 11 and the material, and the protruding material can be effectively limited and fixed by the pressing block 11, so that the equipment can adapt to different shapes of the material punching;

[0035] The positioning piece 3 in the equipment can effectively position and clamp the four corners of the material, so as to ensure the stability of the material during punching, avoid the shaking or inaccurate punching of the equipment during punching, and the jacking plate 13 in the equipment cooperates with the positioning piece 3, the universal ball 7 and the pressing block 11, so that the equipment can punch different shapes of materials during use, thereby further reducing the disadvantages of the equipment during punching, improving the punching accuracy of the equipment, and further improving the practicality and use convenience of the equipment.
