Description
Technical Field
[0001] This utility model relates to the field of hardware stamping die technology, and in particular to a hardware stamping and cutting mechanism based on a stamping die. Background Technology
[0002] like Figure 1 The PIN pins shown in the image are currently subject to common problems in the mold technology used to produce such metal stamping products, including incomplete removal of the product root and burrs on the contact surface of the PIN pins. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a metal stamping and cutting mechanism based on a stamping die. Therefore, this invention offers a highly efficient and precise metal stamping and cutting mechanism, significantly improving product quality and production efficiency.
[0004] This utility model is achieved through the following technical solution: a hardware stamping and cutting mechanism based on a stamping die, comprising: a cutting slider symmetrically slidably disposed within a stripper plate of an upper die base, and a side-blade punch and a cutting punch disposed on the upper die base, which sequentially push the cutting slider forward and perform cutting when the upper and lower die bases are closed. The cutting slider is provided with left-right movable springs that can push the cutting slider to move left and right, and up-down movable springs that can push the cutting slider to move up and down. When the stripper plate is pressed, the cutting slider is 0.1-0.5mm away from the product strip to avoid friction with the product. After the side-blade punch pushes the cutting slider to the designated position to be cut, the cutting punch moves downward to the bottom to achieve the strip cutting state.
[0005] Furthermore, the end faces of the side-blade punch and the cutting slider that come into contact are set as matching bevels.
[0006] Furthermore, the cutting slider includes a sliding part and a cutting part, a left and right movable spring is disposed between the sliding part and the cutting part, an up and down movable spring is disposed in the cutting part, the cutting part has a cutting blade, and the cutting blade is provided with a clearance groove.
[0007] The beneficial effects of this utility model are:
[0008] This metal stamping and cutting mechanism effectively solves the problems of incomplete removal of the product root and burrs on the PIN contact surface through an innovative cutting slider and spring structure design. The cutting slider maintains a tiny 0.1 mm gap with the product strip during material removal, preventing friction damage. The beveled design of the side punch and the cutting slider ensures precise positioning of the slider to the predetermined cutting position. Internal left-right and up-down moving springs control the slider's left-right and up-down movement respectively, ensuring the stability and accuracy of the cutting action. The cutting blade and clearance groove further improve the cutting quality, resulting in a smoother cut surface. This invention, through optimized mold structure, enables the removal of the product root while ensuring burr-free contact with the PIN, while also saving materials, reducing costs, providing accurate positioning, high stability during production, and preventing product deformation.

[0013] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0014] Please see Figure 2 and Figure 3 This embodiment provides a metal stamping and cutting mechanism based on a stamping die. The metal stamping and cutting mechanism includes a stripper plate 11, a cutting slider 12, a side blade punch 13, and a cutting punch 14 respectively disposed on the upper die base 10.
[0015] The ejector plate 11 is mounted on the upper mold base 10 and is used to press down the product strip 30. After the product strip 30 enters between the upper mold base 10 and the lower mold base 20, the upper mold base 10 moves down to close with the lower mold base 20, so that the ejector plate 11 presses down on the product strip 30. The ejector plate 11 is provided with a mounting block 15, which has a punching port. Two cutting sliders 12 are provided, which are symmetrically slidably mounted on the punching port. The mounting block 15 is provided with guide holes for the side cutting punch 13 and the cutting punch 14 to pass through and push the cutting sliders 12 to perform punching. When the upper mold base 10 and the lower mold base 20 are closed, the ejector plate 11 is driven to move down to press down on the product strip 30, and the cutting sliders 12 on both sides of the punching port have a gap of 0.1mm from the product strip 30. The upper mold base 10 continues to move down, so that the side cutting punch 13 passes through the punching port to press down on the product strip 30. After the punch 13 pushes the cutting slider 12 to the designated position to be cut off, the upper die base 10 continues to move down, causing the cutting punch 14 to continue pushing the cutting slider 12, thereby causing the cutting slider 12 to cut off the waste material connected to the product strip 30. By optimizing the mold design, the cutting slider 12 first moves to the designated position to be cut off, and then presses down to cut off the excess root of the product, while simultaneously discharging the waste material. The cut waste material flows out through the discharge port of the lower die base 20. This design not only improves the cutting accuracy, but also ensures the stability of the product strip 30 during the cutting process. The cooperation between the cutting slider 12 and the side-blade punch 13 achieves precise waste material removal, avoids the deviation that may occur in the traditional cutting method, and effectively prevents residual burrs at the waste material removal end of the product.
[0016] In an optional embodiment, the cutting slider 12 includes a sliding part 120 and a cutting part 121. A left-right movable spring 122 is provided between the sliding part 120 and the cutting part 121. The left-right movable spring 122 can push the cutting slider 12 to move left and right. The cutting part 121 has a cutting blade 123 with a clearance groove 124. An up-down movable spring 125 is provided at the upper end of the cutting part 121. The up-down movable spring 125 can push the cutting slider 12 to move up and down. When the side punch 13 pushes the cutting slider 12 to the preset cutting position, the cutting blade 123 of the cutting part 121 is facing the two ends of the product and the waste material. The protruding part of the product is located in the clearance groove 124, so that the cutting slider 12 can cut off the waste material without interfering with the product. This ensures that the product will not collide and deform when punching the waste material. The left-right movable spring 122 and the up-down movable spring 125 make the cutting slider 12 automatically reset.
[0017] In an optional embodiment, in order to gradually push the cutting slider 12 to the designated cutting position as the side-blade punch 13 descends, the end faces of the side-blade punch 13 and the sliding part 120 that contact each other are configured as matching bevels. The bevel design allows the side-blade punch 13 to gradually and smoothly push the cutting slider 12 to the preset cutting position during its descent. This bevel design ensures that the cutting slider 12 slides smoothly along a preset path when pushed by the side-blade punch 13, avoiding the jamming or offset that may occur in conventional methods, thereby further improving the cutting accuracy and efficiency.
[0018] In summary, the metal stamping and cutting mechanism based on a stamping die provided by this utility model achieves high-precision cutting of waste material on the product strip 30 by rationally designing the cooperative relationship of the strip 11, the cutting slider 12, the side-blade punch 13, and the cutting punch 14, while ensuring the stability of the product strip 30 during the cutting process. The design of the cutting slider 12 first advancing to the designated position to be cut, and then pressing down to cut off the excess root of the product, not only improves the cutting accuracy but also effectively prevents the problem of residual burrs at the waste removal end of the product. In addition, the setting of left and right movable springs 122 and up and down movable springs 125 enables the cutting slider 12 to automatically reset, further improving the cutting efficiency and product quality. The inclined surface design allows the cutting slider 12 to slide smoothly when pushed by the side-blade punch 13, avoiding jamming or deviation, thereby further improving the cutting accuracy and efficiency.
[0019] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
