The shape of the receiving groove 220 is the same as the shape of the second groove 180, and the position corresponds to the position. In the present embodiment, the shape of the indenter 22 is a rectangular parallelepiped shape.

The punching blade 24 is used to die cut the raw material of the product. The punching blade 24 is received in the receiving groove 220. The shape of the punching blade 24 corresponds to the shape of the receiving groove 220. The punching blade 24 is slidable along the receiving groove 220 in the ram 22 .

The punching knife 24 includes a large punching knife 242 and a plurality of small punching blades 244. The large punching knife 242 is received in the receiving groove 220 and has a shape matching with the receiving groove 220. The large punching blade 242 is provided with a plurality of first through holes 2422 and a plurality of second through holes 2424. In this embodiment, the aperture of the first through hole 2422 is larger than the aperture of the second through hole 2424. The small punching knife 244 is fixedly disposed in the first through hole 2422. One end of the small punching knife 244 away from the padding plate 10 is flush with the large punching blade 242, and the other end is protruded from the large punching blade 242. The small punch 244 is used to punch a hole in the product material. In the embodiment, the small punching knife 244 has a cylindrical shape, and the punching blade 24 includes two small punching blades 244. Two of the small punching blades 244 are respectively disposed at opposite ends of the large punching blade 242.

The plurality of top pins 26 are used to separate the punched product material from the small punch 244. The plurality of top pins 26 are received in the second through holes 2424. In this embodiment, the top pin 26 is T-shaped and includes a pin head 262 and a pin 264. The pin head 262 abuts against one end of the large punching knife 242 away from the padding plate 10. The pin 264 is received in the second through hole 2424. The pin 264 is away from the One end of the pad board 10 is fixed to the pin head 262, and the other end is adjacent to the pad board 10 and is protruded from the large punching blade 242.

When the punching device 100 is assembled, the small punching blade 244 and the topping pin 26 are respectively placed in the first through hole 2422 and the second through hole 2424, and then glued or the like. The small punching knife 244 is fixed in the first through hole 2422; then the punching blade 24 is installed in the receiving groove 220, and the spring 27 is fixedly disposed on the pin head 262, One end of the locking screw 28 is fixed on the spring 27, thereby completing assembly of the punching structure; then assembling the first substrate 12, the second substrate 14, the two connecting members 16, and the third substrate 18, completing the assembly of the pad board 10, and arranging the ram 22 directly above the pad board 10, so that the position of the second groove 180 is opposite to the position of the receiving groove 220 correspond. Finally, the other end of the locking screw 28 is fixed in the top mechanism 30, thereby completing the assembly of the punching device 100.

In use, the product material is placed on the third substrate 18, and the top mechanism 30 drives the ram 22 to move downward together with the punching knife 24 until the ram 22 is against the product material. The indenter 22 is stopped by the product material to stop moving, and the punching knife 24 continues to move downward, thereby punching out the hole first in the product material. At this time, the end of the small punching knife 244 is wrapped in the raw material of the product, the top The protruding portion at one end of the pin 26 contacts the product material and is retracted upwardly into the large punching knife 242 such that the spring 27 is tightened and compressed. The large punching knife 242 then continues to die downwardly, causing the large punching knife 242 to die cut out the desired product shape in the product stock. At this time, the spring 27 is reversely stretched, and the top pin 26 separates the product from the small punch 244 under the restoring force of the spring 27. The last punched product falls directly into the second recess 180 and falls onto the first substrate 12 via the first recess 140, eliminating the need for manual reclaiming.

The punching device 100 provided by the present invention utilizes the interaction between the punching blade 24 and the top pin 26 by the interaction of the punching structure 20, the padding plate 10 and the top mechanism 30. No need to provide a scraper on the periphery of the indenter 22, so that the product material can be finished in the case where the indenter completes a punching motion, and the finished product passes through the second groove 180 and the first A groove 140 automatically falls onto the first substrate 12 without manual take-up, which simplifies the manufacturing process and improves the production efficiency of the product. And when die cutting, the indenter 22 does not come into contact with the product, reducing the probability of the product being crushed.

In addition, those skilled in the art can make other changes in the spirit of the present invention. Of course, the changes made according to the spirit of the present invention should be included in the scope of the present invention.
