DETAILED DESCRIPTION

[0024] The technical schemes in the embodiments of the present application will be clearly and completely described in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0025] Please refer to Figures 1-4 The present application provides a novel three-side punching die, which comprises:

[0026] The upper die holder 1 is provided with the upper backing plate 2 at the bottom, the upper clamping plate 3 at the bottom of the upper backing plate 2, the upper supporting plate 4 at the bottom of the upper clamping plate 3, and the upper die punch 14 penetrating through the upper clamping plate 3 and the upper supporting plate 4 and extending from the bottom of the upper supporting plate 4.

[0027] The lower die holder 7 is provided with the lower backing plate 6 at the top surface, and the lower die plate 5 at the top surface of the lower backing plate 6.

[0028] The side punching assembly is arranged on the top surface of the lower die plate 5, and comprises a spring 9. Both sides of the top of the lower die plate 5 are provided with sliding channels 15. One end of the spring 9 is fixedly connected with a mounting plate 10. One side of the mounting plate 10 is provided with a sliding plate 17 which is slidingly connected in the inner cavity of the sliding channel 15. The top of the sliding plate 17 is provided with a sliding block 12. The top surface of the lower die plate 5 is provided with an auxiliary plate 19 which is located between the sliding channel 15 and the center of the lower die plate 5. The bottom of the upper backing plate 2 is connected with an upper die insert 8 which passes through the upper clamping plate 3 and the upper supporting plate 4 and extends from the bottom of the upper supporting plate 4. One side of the sliding block 12 is connected with a side punching pin 13 which passes through the auxiliary plate 19. The other end of the spring 9 is fixedly connected with an external fixing member. The upper die seat 1, the upper backing plate 2, the upper clamping plate 3 and the upper supporting plate 4 move up and down by using external power. The center of the top of the lower die plate 5 is provided with a product 18.

[0029] Both sides of the top of the lower die plate 5 are fixedly connected with punching inserts 16 which are located between the center of the lower die plate 5 and the upper die punch 14. Both the front and rear sides of the top of the lower die plate 5 are connected with positioning blocks 11. The four edges of the positioning blocks 11 which are close to each other are all arranged as inclined surfaces. The four edges of the punching inserts 16 which are close to each other are all arranged as inclined surfaces. The side surface of the punching insert 16 is provided with a hole which matches the side punching pin 13. The center of the lower die plate 5 is provided with the punching inserts 16 and the positioning blocks 11, so that the product 18 can be placed in the square ring surrounded by the two punching inserts 16 and the two positioning blocks 11, and the product 18 can be positioned, thereby improving the accuracy of punching.

[0030] The edge of the sliding block 12 which is close to the upper die insert 8 is arranged as an inclined surface. The edge of the upper die insert 8 which is close to the sliding block 12 is arranged as an inclined surface. The inclined surface on the sliding block 12 matches the inclined surface on the upper die insert 8. When the upper die insert 8 is pressed down, the downward force of the upper die insert 8 can be converted into a pushing force on the sliding block 12, so that the side punching pin 13 can move and punch the side surface of the product 18.

[0031] When the spring 9 is in a free state, the inclined surface on the sliding block 12 is located below the inclined surface on the upper die insert 8. When the spring 9 is in a free state, the inclined surface on the sliding block 12 is located below the inclined surface on the upper die insert 8, so that the upper die insert 8 can be in contact with the sliding block 12 when the upper die insert 8 is pressed down to a certain distance, and the position of the sliding block 12 can be controlled.

[0032] The distance between the side of the sliding block 12 which is close to the mounting plate 10 is equal to the width of the upper die insert 8. The bottom of the upper die insert 8 is located below the bottom of the upper die punch 14. The distance between the side of the sliding block 12 which is close to the mounting plate 10 is equal to the width of the upper die insert 8, so that after the inclined surface on the upper die insert 8 and the inclined surface on the sliding block 12 are staggered, the upper die insert 8 can be fixed between the sliding block 12 and the mounting plate 10, thereby fixing the position of the product 18 and facilitating punching.

[0033] The side punching assembly is symmetrically arranged on the top of the lower die plate 5, and the side of each of the two sliders 12 close to each other is provided with a plurality of side punching pins 13. By arranging the plurality of side punching pins 13 on the side of each of the two sliders 12 close to each other, the plurality of holes can be punched on the side of the product 18, and the work efficiency is improved.

[0034] The front and rear sides of the slider 12 are symmetrically arranged with the slide 15, and the side section of the slide 15 is in an inverted L shape. By the shape characteristics of the slide 15, the slider 12 is placed between the two slides 15 and moved, and the stability of the movement is improved.

[0035] Working principle: when the device is used, the product 18 is placed upside down in the square ring surrounded by the two punching inserts 16 and the two positioning blocks 11, and the opening of the product 18 is ensured to be downward, the upper die seat 1, the upper pad plate 2, the upper clamping plate 3 and the upper supporting plate 4 are moved downward by the external power, and the upper die punch 14 and the upper pad plate 2 are moved downward, respectively, since the bottom of the upper die insert 8 is below the bottom of the upper die punch 14, the bottom of the upper die insert 8 first contacts the inclined surface on the slider 12, the bottom inclined surface of the upper die insert 8 contacts the inclined surface on the slider 12, the slider 12 and the side punching pin 13 are pushed to move towards the center of the lower die plate 5, at this time, the slide plate 17 moves in the slide 15, and the spring 9 is in the stretched state, when the upper die insert 8 and the upper die punch 14 continue to move downward, the upper die punch 14 and the side punching pin 13 punch the top and the two sides of the slide 15, respectively, after the punching is completed, the external power drives the upper die seat 1, the upper pad plate 2, the upper clamping plate 3 and the upper supporting plate 4 to move upward, at this time, the spring 9 moves the slider 12 to the initial position by the elastic force, and then the punched product 18 is taken out from the top of the lower die plate 5, and thus a stamping cycle is completed.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
