When in use, the upper die moves toward the lower die, the movable insert presses down the fixed insert, and the punch is tangent to the edge of the fixed insert to complete the shearing action. This method of straight punching up and down often has the problem of not cutting cleanly when cutting the product, and the edge after cutting has a serrated shape, which seriously affects the appearance requirements of the product. Summary of the invention

[0003] The object of the present invention is to provide a diaphragm side punching device to solve the problem of sawtooth on the edge after cutting by the up and down straight punching cutting method.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] The diaphragm side punching device comprises a first mold and a second mold which are arranged opposite to each other in the vertical direction, wherein the first mold comprises a diaphragm fixed insert, and the second mold comprises a diaphragm movable insert and a punch, wherein:

[0006] The first mold is also provided with a side punch block, which is arranged at the rear end of the diaphragm fixing insert. The rear end of the diaphragm fixing insert is provided with a first protrusion, and the side punch block can move along an inclined surface, and the inclined surface faces downward at one end of the diaphragm fixing insert;

[0007] The rear side of the punch is provided with a second protrusion, wherein

[0008] The lower surface of the first protrusion, the lower surface of the second protrusion and the upper surface of the side punch are parallel, and when the first mold is completely docked with the second mold, the lower surface of the first protrusion and the lower surface of the second protrusion are on the same plane, and the side punch is tangent to the first protrusion and the second protrusion at the same time.

[0009] When the first mold is docked with the second mold, the second protrusion is tangent to the first protrusion in the vertical direction, the side punch moves along the first sliding direction on the inclined surface, and the lower surface of the first protrusion and the lower surface of the second protrusion are on the same plane and are tangent to the upper surface of the side punch at the same time.

[0010] When the first mold and the second mold are docked, the second protrusion is tangent to the first protrusion in the vertical direction, the side punch block cuts down along the first sliding direction, the front end of the diaphragm is pressed by the diaphragm movable insert, and the rear end of the diaphragm is longitudinally cut by the second protrusion. At the same time, the side punch block moves along the inclined surface and finally becomes tangent to the lower surfaces of the first protrusion and the second protrusion. The rear end of the diaphragm is side-cut again by the side punch block. After two punchings, and the second punching is in the form of side cutting, there is no serrated part on the edge of the diaphragm after punching.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] The present invention provides a diaphragm side punching device, such as Figure 1 As shown, the diaphragm side punching device includes a first mold 100 and a second mold 200 which are opposite to each other in the vertical direction. The first mold 100 and the second mold 200 are butted against each other in the vertical direction to complete the punching of the diaphragm.

[0040] See also Figure 2 and Figure 4 The first mold 100 is provided with a diaphragm fixing insert 1 and a side punch block 2. The side punch block 2 is movably arranged at the rear end of the diaphragm fixing insert 1 along an inclined surface. The side punch block 2 moves along a first sliding direction and gradually approaches the diaphragm fixing insert 1. The side punch block 2 moves along a second sliding direction and gradually moves away from the diaphragm fixing insert 1. The first sliding direction and the second sliding direction are opposite.

[0041] See also Figure 3 and Figure 4 The second mold 200 is provided with a diaphragm movable insert 3 and a punch 4. The diaphragm movable insert 3 protrudes further toward the first mold 100 than the punch 4, thereby first pressing the diaphragm on the diaphragm fixed insert 1. The punch 4 is arranged at the rear end of the diaphragm movable insert 3. When the first mold 100 is docked with the second mold 200, the diaphragm movable insert 3 presses the diaphragm, and the punch 4 is tangent to the diaphragm fixed insert 1 in the vertical direction.

[0042] Continue to see Figure 5 , the rear end of the diaphragm fixed insert 1 is provided with a first protrusion 1A, and the rear side of the punch 4 is provided with a second protrusion 4A. When the first mold 100 and the second mold 200 are completely docked, the second protrusion 4A is tangent to the first protrusion 1A in the vertical direction, and the lower surface of the first protrusion 1A and the lower surface of the second protrusion 4A are on the same plane and tangent to the upper surface of the side punch block 2. That is, when the first mold 100 and the second mold 200 are docked, the second protrusion 4A moves in the vertical direction, and the side punch block 2 slides down along the first sliding direction. The front end of the diaphragm is first pressed by the diaphragm movable insert 3, and the rear end of the diaphragm is subjected to a longitudinal cut by the second protrusion 4A. At the same time, the side punch block 2 moves along the first sliding direction and finally tangent to the lower surface of the first protrusion 1A and the second protrusion 4A. The rear end of the diaphragm continues to be side-cut by the side punch block 2, and there is no serrated part on the edge of the diaphragm after punching.

[0043] Continue to see Figure 1 and Figure 4 The first mold 100 is further provided with a slide 10, the upper surface of the slide 10 extends along the first sliding direction, and the side punch block 2 is slidably arranged on the upper surface of the slide 10. The side punch block 2 is slidably arranged on the slide 10, and the surface of the slide 10 extends along the first sliding direction, so that the movement direction of the side punch block 2 is better restricted.

[0044] A plurality of elastic members 11 are provided at the rear side of the slide 10. In this embodiment, three elastic members 11 are provided at the rear side of the slide 10. The elastic members 11 are elastically connected to the rear end of the side punch 2. The elastic members 11 apply a pulling force to the side punch 2 to move along the second sliding direction. That is, the elastic members 11 pull the side punch 2 to move obliquely upward along the surface of the slide 10.

[0045] like Figure 4 The elastic member 11 includes a fixed bracket 111, a spring 112 and a connecting rod 113. The fixed bracket 111 is provided with a through hole. The arrangement direction of the connecting rod 113 is parallel to the surface of the slide 10. The connecting rod 113 passes through the through hole of the fixed bracket 111. One end of the connecting rod 113 is fixedly connected to the side punch block 2. The other end of the connecting rod 113 is provided with a spring 112 between the fixed bracket 111. The spring 112 applies a pulling force to the connecting rod 113 to make it move along the second direction.

[0046] The second mold 200 includes a shovel base 5, which has a side surface that is in sliding contact with the rear end face of the side punch block 2. The shovel base 5 is configured to be able to slide against the rear end face of the side punch block 2 and exert a force on the latter to move along the first sliding direction on the slide 10. That is, when the second mold 200 moves downward, the shovel base 5 gradually approaches the side of the side punch block 2 at the initial position at this time, and then the shovel base 5 presses down the side punch block 2 and the two are in surface contact, the side punch block 2 overcomes the tension of the elastic member 11, and drives the side punch block 2 to move along the first sliding direction. It should be noted that once the shovel base 5 is withdrawn, that is, the side punch block 2 continues to be pulled by the elastic member 11, the second mold 200 gradually moves away from the first mold 100 and moves along the second sliding direction to return to its original position; when the second mold 200 continues to press down, the side punch block 2 continues to move along the first sliding direction, and so on.

[0047] The first mold 100 is also provided with a plurality of diaphragm positioning blocks 6. In the present embodiment, there are two diaphragm positioning blocks 6, which are respectively arranged on the left and right sides in front of the diaphragm fixing insert 1. The two diaphragm positioning blocks 6 are configured to abut against the front edge of the diaphragm to prevent the diaphragm from sliding off the diaphragm fixing insert 1.

[0048] Correspondingly, the punch 4 is provided with two grooves 40 , and the grooves 40 correspond one to one with the diaphragm positioning blocks 6 along the vertical direction.

[0049] Furthermore, the first mold 100 is provided with positioning holes 12 at the edge, and the second mold 200 is provided with positioning rods 13 corresponding to the positioning holes 12, and the positioning rods 13 correspond to the positioning holes 12 one by one along the vertical direction. Of course, the positioning rods 13 can also be provided on the first mold 100, and the positioning holes 12 can be provided on the second mold 200, and the present invention is not limited to this.

[0050] Furthermore, the first mold 100 is also provided with a first guide platform 71, and the first guide platform 71 is arranged on both sides of the diaphragm fixed insert 1. The second mold 200 is also provided with a second guide platform 72, and the second guide platform 72 is arranged on both sides of the diaphragm movable insert 3. The first guide platform 71 can fit with the second guide platform 72 along their respective inclined surfaces.

[0051] The first mold 100 is further provided with an anti-misalignment column 81 , which is disposed at the front side of the diaphragm fixing insert 1 , and the second mold 200 is provided with an anti-misalignment hole 82 that cooperates with the anti-misalignment column 81 .

[0052] The edges of the first mold 100 and the second mold 200 are provided with a plurality of mutually cooperating edge lock groups 9. The edge locks 9 include concave edge locks and convex edge locks. In this embodiment, the concave edge locks are provided on the first mold 100, and the convex edge locks are provided on the second mold 200.

[0053] It should be noted that, when the second mold 200 approaches the first mold 100, it is first aligned with the positioning hole 12 through the positioning rod 13, and then the first guide platform 71 and the second guide platform 72 are aligned and matched again, the anti-misalignment column 81 and the anti-misalignment hole 82 are matched, and the side lock groups 9 are matched with each other.

[0054] That is, the height of the positioning rod 13 is greater than the heights of the first guide platform 71 , the second guide platform 72 , the anti-misalignment column 81 and the side lock assembly 9 .
