The airbag 32 is fixed to a notch position near the movement groove 17, and the pulling cord 16 penetrates the airbag 32. The air tap 33 is fixedly installed on the side wall of the material returning plate 4, the air tap 33 penetrates through the material returning plate 4 and is fixedly communicated with the air bag 32, and the air injection direction of the air tap 33 faces the material guiding part 31.
When the hinge seat 13 corresponding to the movable separation blade 11 moves towards the feeding port far away from the feeding portion 10, the hinge seat 13 corresponding to the movable separation blade 11 extrudes the air bag 32, air is ejected through the air tap 33, and the air blows off the scraps on the guiding portion 31. Simultaneously, the blown-out gas is favorable for assisting in blowing off the waste material, so that the collection and cleaning of the waste material are more convenient. When the compression of the air bag 32 is released, the air bag 32 is reset by the self elastic force.
It should be added that, referring to fig. 5, the buffer assembly includes a plurality of third springs 34 and four guide bars 35. The third springs 34 are respectively and fixedly installed between the tapping plate 3 and the material returning plate 4. Four guide rods 35 are respectively fixed at the end angle positions of the fixed tapping plate 3, and the four guide rods 35 respectively penetrate through the material returning plate 4 and the template 5 and are respectively in sliding connection with the material returning plate 4 and the template 5.
Working principle of waste material guide structure of stamping die:
when a die is required, the material is first placed on the lower die. When the upper die 1 punches downwards, the die of the lower die punches the material into the punch holes 6 in the die plate 5 under the cushioning effect of the third spring 34, and the die of the lower die pushes the punched scrap into the feeding portion 10. In the process that the waste material is jacked into the feeding part 10, the waste material drives simultaneously and separates the separation blade 11 and decide separation blade 12 and open, and in continuous punching process, moves separation blade 11 and decides separation blade 12 and carry out the bearing to the waste material simultaneously, reduces the condition that the waste material dropped from punching press nib 6. And the waste pushed in from the rear pushes the waste pushed in from the front into the bending part 9, and finally the waste in front automatically slides off from the inclined part 8. And (5) completing automatic cleaning and collection of waste materials.
To sum up, the waste material sequentially passes through the feeding portion 10, the bending portion 9 and the inclined portion 8, and finally falls off from the side wall of the material returning plate 4, thereby being beneficial to improving the convenience of cleaning the punched and ejected waste material.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
