[0022] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] Reference Figures 1 to 6 This embodiment provides a side-punching structure for metal parts, including a movable base 1, a punching assembly 2 disposed on one side of the movable base 1, a pressure member 3 disposed on one side of the punching assembly 2, a guide pull-back member 4 connecting the movable base 1 and the pressure member 3, and a push block 5 for pushing the movable base 1, the push block 5 being disposed on the other side of the movable base 1 opposite to the pressure member 3. Specifically, the push block 5, movable base 1, punching assembly 2, and pressure member 3 are arranged sequentially. In specific implementation, the structure of this utility model needs to be connected with other structures of the stamping die to facilitate punching and material ejection during die closing and opening processes, for example, the movable base 1 is connected to the lower die base.

[0024] The guide pull-back component 4 includes a connecting part 41 connected to the side of the movable seat 1, a guide arm 42 connected to the connecting part 41, and a hook part 43 disposed at the end of the guide arm 42. The side wall of the pressure component 3 is provided with a first guide groove 31 that cooperates with the guide arm 42. The bottom surface of the first guide groove 31 near the end of the movable seat 1 is provided with a step part 32 that cooperates with the hook part 43. The hook part 43 can hook the step part 32 to restrict the movement direction of the movable seat 1, thereby pulling the movable seat 1 back when the mold is opened. In this embodiment, two guide pull-back components 4 are symmetrically arranged, respectively disposed on two opposite sides of the movable seat 1. With the cooperation of the guide pull-back component 4, the first guide groove 31, and the step part 32, this utility model can guide the movement of the pressure component 3 when the mold is closed, and also limit the movement of the movable seat 1 to reset when the mold is opened. It eliminates the need for numerous guide rods, limit rods, and other components, simplifying the mold structure, reducing the complexity of the mold, and reducing the manufacturing cost of the mold.

[0025] like Figure 3As shown, the punching assembly 2 includes a punching seat 21 connected to the side of the movable seat 1 and a punching part 22 disposed on the side of the punching seat 21 facing the pressure member 3. The pressure member 3 is provided with a through hole 33 at the position corresponding to the punching part 22, and the punching part 22 is inserted into the through hole 33. The shape of the punching part 22 can be designed according to the shape of the punching required, such as circular, square, etc. In this embodiment, it is circular. When the push block 5 pushes the movable seat 1, the pressure member 3 is pushed and moves simultaneously to press the part (hereinafter referred to as workpiece 9), ensuring that the workpiece 9 will not deviate during punching. As the movable seat 1 continues to move, the end of the punching part 22 of the punching assembly 2 passes through the through hole 33 to punch the workpiece 9. During the mold opening process after punching, the movable seat 1 is reset under the action of the push block 5. At this time, the guide pull-back part 4 moves accordingly until the hook part 43 and the step part 32 contact, pulling the pressure member 3 away from the workpiece 9. At this time, the punched workpiece 9 can be taken out. This utility model achieves a continuous action of pressing material first and then punching by cooperating with the hook part 43 of the guide pull-back member 4 and the step part 32 of the pressure member 3, thus ensuring the punching quality.

[0026] like Figure 4 As shown, the pressing component 3 is provided with a first recessed portion 34 that cooperates with the punch seat 21. During the mold closing process, the end of the punch seat 21 is inserted into the first recessed portion 34, which can reduce the space occupied by the entire structure on the one hand, and also play a guiding and positioning role on the other hand.

[0027] Both the upper and lower ends of the hook portion 43 facing the step portion 32 are chamfered. The chamfer reduces the height of the surface, so that the size of the surface is smaller than the width of the first guide groove 31, which makes it easier for the hook portion 43 to enter the first guide groove 31. At the same time, it can also reduce the impact force when the hook portion 43 contacts the step portion 32 to a certain extent.

[0028] The movable seat 1 has a second recess 11 on its side, and the connecting part 41 is connected to the second recess 11. The connecting part 41 can be connected to the second recess 11 by fasteners.

[0029] The height of the step portion 32 is less than the depth of the first guide groove 31. This arrangement ensures that the guide arm 42 slides within the first guide groove 31 without affecting the engagement between the hook portion 43 and the step portion 32. The movable seat 1 is provided with a first inclined surface 12 for contacting the push block 5, and the push block 5 is provided with a second inclined surface 51 that engages with the first inclined surface 12. The engagement of the two inclined surfaces (first inclined surface 12 and second inclined surface 51) allows the vertical movement of the push block 5 to be converted into the horizontal movement of the movable seat 1. When the push block 5 is pushed downwards during mold closing, it can push the movable seat 1 to move horizontally, achieving the side punching action. The same principle applies during mold opening.

[0030] The push block 5 has a guide member 6 on its side, and the movable seat 1 has a second guide groove 13 on its side that cooperates with the guide member 6. The second guide groove 13 is inclined relative to the bottom surface of the movable seat 1. The end of the guide member 6 has a guide portion connected to the second guide groove 13. The inclination direction of the second guide groove 13 is consistent with the inclination direction of the first inclined surface 12 (i.e., they are parallel). Through the cooperation between the guide member 6 and the second guide groove 13, it is ensured that the movable seat 1 moves along a predetermined trajectory under the push of the push block 5 when the mold is closed, avoiding deviation. When the mold is opened, the guide member 6 can also pull the movable seat 1 to reset. In this embodiment, two guide members 6 are also symmetrically arranged, with the two guide members 6 respectively arranged on opposite sides of the push block 5.

[0031] The metal part side punching structure also includes two guide seats 7 disposed on both sides of the moving seat 1 in the moving direction. The moving seat 1 has a guide part 14 on its side that cooperates with the guide seats 7. The guide seats 7 are fixed on the lower die base of the stamping die. The cross-section of the guide seats 7 is L-shaped, which can both guide and limit the movement of the moving seat 1.

[0032] The metal part side punching structure also includes two limiting blocks 8 disposed at both ends of the moving seat 1 in the moving direction, which can play a limiting role when the moving seat 1 moves to the limit position, that is, limit the stroke of the moving seat 1.
