[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] An embodiment of the present invention discloses a punching device for shoe production.

[0025] The present invention provides a punching device for shoe production as Figure 1-2 shown, which includes a base 1. A frame 2 is fixedly provided on the top of the base 1. A cylinder 3 is fixedly provided on the top of the frame 2. The end of the piston rod of the cylinder 3 is fixedly provided with a mounting plate 4. A plurality of uniformly distributed punching needles 5 are fixedly provided on the lower surface of the mounting plate 4. A punching table 6 is fixedly provided on the top of the base 1. A plurality of uniformly distributed needle holes 7 are formed on the upper surface of the punching table 6. The plurality of punching needles 5 and the plurality of needle holes 7 are arranged in a one-to-one correspondence in position, and the punching needles 5 are slidably connected to the needle holes 7. A material receiving groove 8 is provided at the bottom of the punching table 6, and a material receiving box 9 is provided inside the material receiving groove 8. Both sides of the material receiving box 9 are in sliding contact with both sides of the material receiving groove 8, and a handle is fixedly provided on the side wall of the material receiving box 9. The lower ends of the plurality of needle holes 7 are respectively corresponding to the internal storage area of the material receiving box 9. The material receiving box 9 can be directly pulled out from the inside of the material receiving groove 8 through the handle.

[0026] Punching process: By controlling the extension action of the cylinder 3, the cylinder 3 can drive the plurality of punching needles 5 on the mounting plate 4 to move downward, so that the plurality of punching needles 5 move into the plurality of needle holes 7 on the punching table 6, thereby enabling punching operations on the shoe upper surface of the punching table 6. The waste generated during the punching process will be pressed down by the punching needles 5 to the lower ends of the needle holes 7 and fall into the inside of the material receiving box 9, so that the material receiving box 9 can be taken out manually and the waste can be centrally cleaned.

[0027] As Figure 1 and 3As shown in the figure, pressing rods 10 are elastically arranged on both sides of the mounting plate 4. Lower pressing plates 11 are fixedly arranged at the lower ends of the two pressing rods 10. The lower pressing plates 11 are L-shaped pressing plates, and the lower pressing plates 11 are in clamping fit with the corner at one side of the punching table 6. A sliding sleeve 12 is fixedly arranged on the side wall of the mounting plate 4. The rod wall of the pressing rod 10 is slidably arranged inside the sliding sleeve 12. The lower end of the pressing rod 10 is fixedly connected to the lower pressing plate 11, and a fixing block 13 is fixedly arranged at the upper end of the pressing rod 10. A spring 14 is sleeved on the rod wall of the pressing rod 10, and both ends of the spring 14 are fixedly connected to the sliding sleeve 12 and the fixing block 13 respectively.

[0028] Automatic positioning of the shoe upper: Before punching, first lay the shoe upper flat on the upper surface of the punching table 6. During the extension of the control cylinder 3, the pressing rods 10 and the lower pressing plates 11 are driven until the lower pressing plates 11 on both sides move to the corners on both sides of the punching table 6. At this time, the lower pressing plates 11 can press the shoe upper tightly at the corners of the punching table 6. During the continuous extension of the cylinder 3, the pressing rods 10 move inside the sliding sleeves 12 and stretch the springs 14 through the fixing blocks 13. At this time, the pressing rods 10 and the lower pressing plates 11 have the function of elastic expansion and contraction, so as to ensure that the shoe upper is tightly pressed and fixed on the upper surface of the punching table 6, improving the punching accuracy. When the cylinder 3 retracts, the lower pressing plates 11 will separate from the punching table 6, and at this time, the fixation of the shoe upper can be automatically released.

[0029] Finally, in order to improve the stability of punching, as Figure 1 shown, a guide plate 15 is fixedly arranged on the inner side wall of the frame 2. A plurality of punching needles 5 all slide through the inside of the guide plate 15. When the mounting plate 4 and the punching needles 5 are pushed downward, the punching needles 5 slide inside the guide plate 15, which can increase the smoothness of the movement of the punching needles 5.

[0030] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
