Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical scheme, and a detailed implementation manner and a specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a novel punching die, as shown in fig. 1-2, which includes an upper fixing block 1, an upper die base 2, a lower die base 3, a lower die plate 4, a male punch 5, a forming groove 6, and a deformation groove 7;
the top of the upper fixing block 1 is fixedly connected with a driving device (which can be a hydraulic cylinder or a pneumatic cylinder, not shown in the figure), and the bottom of the upper fixing block 1 is fixedly connected with the upper die holder 2. In this embodiment, the upper die holder 2 is fixedly connected to the upper fixing block 1 by screws.
The lower die holder 3 is arranged right below the upper die holder 2, and the top surface of the lower die holder 3 is fixedly connected with the lower template 4. In this embodiment, the lower template 4 is fixedly connected with the lower die base 3 through screws.
The bottom surface of the upper die holder 2 is fixedly connected with the male punch 5, the upper surface of the lower template 4 is provided with a forming groove 6 matched with the male punch 5, the periphery of the forming groove 6 is provided with a deformation groove 7 on the upper surface of the lower template 4, and the inner surface of the deformation groove 7 forms a buffer deformation surface;
in the present embodiment, as shown in fig. 3, the side wall of the buffer deformation surface close to the forming groove 6 forms an included angle with the side wall of the forming groove 6. The forming included angle between the buffering deformation surface and the forming groove is made, so that a knife edge is formed between the buffering deformation surface and the forming groove, the punching process is assisted to be rapidly and accurately realized, the deformation force generated by punching is dispersed to waste materials outside the forming groove range, and the deformation generated in the punching process of the card is reduced. More specifically, in the present embodiment, the included angle between the tangent of the buffer deformation surface near the side wall of the forming groove 6 and the tangent of the side wall of the forming groove 6 is 30 °. Through tests, the included angle of 30 degrees is suitable, the sharpness of the knife edge is not enough due to too large included angle, and the service life of the knife edge is shortened due to too small included angle.
In this embodiment, the outer side of the male punch 5 is provided with a stripping device, and the stripping device is used for cooperating with the male punch 5 to drive the punched waste material to be separated from the male punch 5. The stripper device comprises a stripper plate 8 which is arranged on the outer side of the male punch 5 and can move along the height direction of the male punch 5, the top of the stripper plate 8 is fixedly connected with a limiting column 9, and the upper end of the limiting column 9 can movably penetrate through the upper die holder 2 up and down; and a limiting part 10 is arranged at one end of the limiting column 9 penetrating through the upper surface of the upper die holder 2. In the present embodiment, a first return spring 11 is provided between the stripper plate 8 and the upper die base 2.
In this embodiment, a resetting device for driving the upper die holder 2 to return to the initial position is disposed between the upper die holder 2 and the lower die holder 3. Specifically, the resetting device comprises a first guide column 12 and a second guide column 13, the upper ends of the first guide column 12 and the second guide column 13 respectively penetrate through two sides of the upper die holder 2 in a vertically movable manner, and the lower ends of the first guide column 12 and the second guide column 13 are respectively fixedly connected to two sides of the lower die holder 3; the outer side wall of the first guide column 12 is sleeved with a second return spring 14, and the second return spring 14 is located between the upper die holder 2 and the lower die holder 3.
It should be noted that the mold of this embodiment is a two-end mold, as shown in fig. 2, has two forming grooves, and can be used for punching eight-card-type certificates such as identification cards, that is, 2 × 8 typeset certificates. The three-head die or more three-head dies can be arranged according to the actual production requirements, for example, three forming grooves and matched male punches are arranged for the three-head die, and the three-head die can be used for punching 3-8 typeset certificates.
The working principle of the novel punching die is as follows:
during operation, the card material is placed on the lower template 4, the upper fixing block 1 is driven to move downwards through the driving device, so that the upper die base 2 is driven to move towards the lower die base 3 and compress the second return spring 14, in the downward moving process of the upper fixing block 1, the stripper plate 8 is abutted to the card material outside the range of the forming groove 6 on the upper surface of the lower template 4, the punch 5 continues to move downwards, and at the moment, the first return spring 11 is compressed under the reaction force of the lower template 4. The male punch 5 cuts the card material, and the cut card falls into the forming groove 6.
After the cutting is finished, in the upward process of the male punch 5, the stripper plate 8 is continuously abutted to the waste material of the identification card material outside the range of the forming groove 6 on the lower template 4 under the action of the first return spring 11, the waste material is prevented from going upward along with the male punch 5, and after the male punch 5 is completely separated from the forming groove 6, the stripper plate 8 goes upward along with the upper die base 2 to return to the initial position under the action of the second return spring 14 and the driving device. Wherein, the spacing post 9 plays the guide effect to the motion of taking off flitch 8, and spacing portion 10 guarantees that the upper end of spacing post 9 can not break away from upper die base 2. The first guide post 12 and the second guide post 13 guide the movement of the upper die holder 2.
Various changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
