DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 A punching head guide mechanism of a punch press comprises a base 1, the upper end of the base 1 is fixedly connected to a body 2, the output end of the body 2 is fixedly connected to a punching head 3, the upper end of the base 1 is fixedly connected to a template 4, the upper end of the template 4 is provided with a guide pressing assembly, the guide pressing assembly comprises a pressing plate 6, the lower end of the pressing plate 6 is fixedly connected to a pressing ring 8, the four corners of the lower end of the pressing plate 6 are fixedly connected to guide rods 5, the guide rods 5 are slidably arranged with the template 4, a first spring 7 is sleeved on the guide rod 5 located between the pressing plate 6 and the template 4, the lower end of the punching head 3 is fixedly connected to an auxiliary pressing piece, and the auxiliary pressing piece is matched with the pressing plate 6.

[0024] Specific working principle and implementation method: When the punch head 3 is driven by the machine body 2 to perform punching work, the auxiliary pressing piece at the lower end of the punch head 3 first contacts the pressing plate 6, and by pushing the pressing plate 6 to move downward, the pressing ring 8 at the lower end of the pressing plate 6 presses the plate. Then, under the action of the first spring 7 and the auxiliary pressing piece, the punch head 3 passes through the pressing plate 6 to punch the plate. The guide rods 5 set at the four corners are slidably arranged with the template 4 to achieve a stable punching effect, and the punch head 3 moves to the lower end to press the plate in advance through the auxiliary pressing piece and the pressing ring 8 to avoid vibration and deviation of the plate, thereby improving the punching efficiency and the punching effect. The advantage of such a design is that when the punch head 3 is working, the auxiliary pressing piece and the pressing ring 8 touch the bottom in advance, and the plate is pressed on the upper end of the template 4, and then the punch head 3 punches the plate again, so that the plate can be stably pressed and punched, the deviation of the plate is reduced, and the punching efficiency and the punching effect are improved.

[0025] like Figure 5As shown, the auxiliary pressing part includes a fixed rod 14, the outer side of the fixed rod 14 is provided with a pressing sleeve 15, and the pressing sleeve 15 is fixedly connected with a second spring 16. The lower end surface of the pressing sleeve 15 is arranged below the lower end surface of the punching head 3. When the punching head 3 moves downward, it drives the fixed rod 14 to move downward, and the fixed rod 14 drives the pressing sleeve 15 to move downward. Under the action of the second spring 16, the pressing sleeve 15 starts to shrink, and the pressing sleeve 15 contacts the surface of the pressing plate 6. The pressing plate 6 is pressed downward by the pressing sleeve 15, so that the pressing plate 6 drives the pressing ring 8 downward to press the plate, thereby improving the stability of the stamping process.

[0026] like Figure 2 As shown, the guide rod 5 located at the lower end of the base 1 is fixedly connected to the connecting plate 10, and an adjusting rod 11 is arranged in the middle of the connecting plate 10. The end of the adjusting rod 11 is threadedly connected to the lower end of the base 1, and a third spring 12 is sleeved on the adjusting rod 11 located at the upper end of the connecting plate 10. The lower end of the adjusting rod 11 is fixedly connected to an adjusting frame 13. The third spring 12 is driven to expand and contract by rotating the adjusting rod 11, and the adjusting rod 11 drives the connecting plate 10 to compress and expand the third spring 12. In this way, the pressing height of the upper pressing plate 6 can be fine-tuned according to the thickness of the plate, thereby achieving a finer pressing effect, and the adjusting frame 13 can be more convenient for the user to rotate.

[0027] like Figure 4 As shown, the upper end of the pressing plate 6 is fixedly connected to a support frame 17, and the upper end of the support frame 17 is fixedly connected to a spring sheet 18, the inner end of the spring sheet 18 is inclined and is located at the inner edge of the lower end of the punching head 3; the support frame 17 is fixed to both sides of the upper end of the pressing plate 6, and when the punching head 3 moves downward, it first contacts with the spring sheet 18 at the upper end of the support frame 17, and the spring sheet 18 is squeezed out to both sides of the punching path. After punching, the punching head 3 drives the punched sheet to move upward, and the dropped sheet falls on the spring sheet 18, and the sheet is discharged to the outside through the inclined spring sheet 18, thereby achieving the effect of unloading.

[0028] like Figure 3 As shown, the upper edge of the template 4 is fixedly connected with a discharge chute 19, and the punched sheet material is discharged through the discharge chute 19. The inclined discharge chute 19 guides the sheet material to be discharged.

[0029] like Figure 3 As shown, a shield 20 is fixedly connected to the upper end of the unloading chute 19, and the shield 20 is arranged on a side close to the template 4. The shield 20 can prevent the plate from collapsing when it is separated from the spring piece 18, thereby playing a shielding role.

[0030] like Figure 4As shown, a buffer pad 9 is fixedly connected to the upper end of the pressing plate 6, and the buffer pad 9 is arranged corresponding to the position of the pressing sleeve 15. The buffer pad 9 is arranged corresponding to the position of the pressing sleeve 15, which can reduce the sound between the pressing sleeve 15 and the pressing plate 6 during stamping and reduce the sound of metal collision.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
