Description

Technical Field

[0001] This utility model relates to the field of stamping processing, specifically to a side-push type anti-chip jumping mechanism for stamping. Background Technology

[0002] In traditional front-mounted ejector chip-jumping structures, during the die's ascent to the top dead center of the press, the material is sometimes no longer under the downward spring pressure at a certain point in the stroke. This is especially problematic for long, single-sided cuts, where the lack of a closed system easily causes the scrap to tumble, resulting in chipping. This prevents the scrap from falling properly into the waste collection chute, and in severe cases, it can even clog the chute, damaging the stamping die and disrupting normal production. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a side-push type anti-chip jumping mechanism for stamping. When the waste material falls, both sides are subjected to force simultaneously and continuously, avoiding tilting and tilting, thereby ensuring that no chip jumping occurs.

[0004] The purpose of this utility model is achieved through the following technical solution: This side-push type anti-chip jumping mechanism for stamping includes: The lower die base is fixedly installed on the die core plate. The material to be punched is placed on the die core plate, and a blanking groove is opened on the die core plate. The upper mold base is located above the lower mold base and moves to open and close relative to the lower mold base under the drive of the punch press. An upper template assembly is fixed below the upper mold base. The blanking punch is fixed on the upper template assembly and moves synchronously with the upper die base. The blanking punch punches the material to generate waste. A blanking die core is embedded in a die core plate. A guide groove matching the contour of the scrap material is formed on the blanking die core, and the guide groove is connected to the blanking chute; and The scrap block is slidably installed inside the mold core plate. As the scrap falls along the discharge groove, the scrap block always keeps the scrap against the discharge mold core.

[0005] As a further technical solution, there are two scrap block sliders, located on both sides of the scrap, with the heads of the scrap block sliders facing the unloading die core, so that both ends of the scrap are subjected to continuous force during the falling process.

[0006] As a further technical solution, the scrap block is installed in the slide groove opened in the mold core plate by means of a return spring. In the natural state, the return spring extends, so that the head abuts against the blanking mold core.

[0007] As a further technical solution, the head of the waste slider is provided with a force-bearing end face for contacting the waste and applying pressure. An inlet ramp is provided on the upper part of the force-bearing end face, and an outlet ramp is provided on the lower part of the force-bearing end face.

[0008] As a further technical solution, the mold core plate and the lower mold base are connected by a mold core plate pad.

[0009] As a further technical solution, the blanking die is installed in a positioning groove opened in the die plate.

[0010] As a further technical solution, the upper template assembly includes an upper pad, a fixed plate, a stripper pad, and a stripper plate connected in sequence. The upper pad is fixed to the upper mold base, and the unloading punch passes through the fixed plate, the stripper pad, and the stripper plate in sequence.

[0011] As a further technical solution, a clearance groove is provided on the feeding punch at the position corresponding to the head of the scrap block.

[0012] The beneficial effects of this utility model are as follows: 1. The scrap material punched out by the product is subjected to a continuous lateral thrust from the scrap material blocking slider. There are two scrap material blocking sliders, which are evenly distributed on both sides of the scrap material to ensure that the scrap material will not jump out of the die surface. 2. The head of the scrap slider is provided with a force-bearing end face. The upper part of the force-bearing end face is provided with an inlet ramp to ensure that the material strip enters smoothly. The lower part of the force-bearing end face is provided with an outlet ramp to reduce the scraping between the scrap and the mold core and avoid the generation of powder.

[0025] The present invention will now be described in detail with reference to the accompanying drawings: Example: As attached Figures 1-11 As shown, this side-push type anti-chip-jumping stamping mechanism includes an upper die base 1, an upper pad 2, a fixed plate 3, a stripper plate pad 4, a stripper plate 5, a die core plate 6, a die core plate pad 7, a lower die base 8, a blanking punch 9, material 10, a blanking die core 11, a scrap-catching slider 12, a return spring 13, scrap 14, a slider groove 15, a blanking groove 16, a positioning groove 17, a head 18, a force-bearing end face 19, an inlet inclined surface 20, an outlet inclined surface 21, a guide groove 22, and a clearance groove 23.

[0026] Reference Appendix Figure 1 , 6 A die core plate 6 is fixedly installed on the lower die base 8, and the die core plate 6 is connected to the lower die base 8 through a die core plate backing plate 7. The material 10 to be punched is placed on the die core plate 6, and a blanking groove 16 is opened on the die core plate 6 (e.g., Figure 7 , 8 (As shown).

[0027] Furthermore, such as Figure 1 As shown, the upper die base 1 is positioned above the lower die base 8. Under the drive of the punch press, the upper die base 1 moves in an opening and closing motion relative to the lower die base 8. At the same time, an upper template assembly is fixed below the upper die base 1. The upper template assembly includes an upper pad 2, a fixed plate 3, a stripper plate pad 4, and a stripper plate 5 connected in sequence. The upper pad 2 is fixedly connected to the upper die base 1, and the ejector punch 9 passes through the fixed plate 3, the stripper plate pad 4, and the stripper plate 5 in sequence.

[0028] like Figure 1, 2 As shown, the blanking punch 9 is fixed on the upper template assembly (fixed plate 3) and moves synchronously with the upper mold base 1. The blanking punch 9 punches the material 10 to generate waste material 14.

[0029] Reference Appendix Figure 6 , 7 8. The blanking die core 11 is embedded in the positioning groove 17 opened on the die core plate 6. For example... Figure 3 , 4 As shown, a guide groove 22 matching the contour of the scrap 14 is opened on the blanking die core 11, and the guide groove 22 is connected to the discharge groove 16. The scrap 14 slides down along the guide groove 22 and the discharge groove 16.

[0030] Two slider slots 15 are formed on the die core plate 6. Scrap-holding sliders 12 are slidably mounted in the die core plate 6 (slider slots 15) via a return spring 13. During the process of the scrap 14 falling along the discharge groove 16, the scrap-holding sliders 12 always keep the scrap 14 against the discharge die core 11. Preferably, there are two scrap-holding sliders 12, located on both sides of the scrap 14, with the heads 18 of the sliders facing the discharge die core 11. This ensures that both ends of the scrap 14 are continuously subjected to force during its descent, and the scrap punched from the product is subjected to a continuous lateral thrust from the scrap-holding sliders. The scrap-holding sliders are evenly distributed on both sides of the scrap, ensuring that the scrap does not jump out of the die surface. In its natural state, the return spring 13 is extended, meaning that before cutting, the heads 18 of the scrap-holding sliders 12 are against the discharge die core 11.

[0031] Furthermore, such as Figure 9 , 10 As shown in Figure 11, a force-receiving end face 19 is provided at the head 18 of the scrap slider 12. This force-receiving end face 19 contacts the scrap 14 and applies pressure (lateral thrust). Furthermore, an guide ramp 20 is provided on the upper part of the force-receiving end face 19 to guide the scrap 14 into the force-receiving end face 19, ensuring smooth entry of the material strip. An exit ramp 21 is provided on the lower part of the force-receiving end face 19 to guide the scrap 14 away from the force-receiving end face 19, while also reducing scraping between the scrap and the mold core, thus preventing the generation of dust.

[0032] like Figure 2 , 4 As shown, a clearance groove 23 is provided on the feeding punch 9 at a position corresponding to the head 18 of the scrap block 12, so that the head 18 can be cleared during the downward movement of the feeding punch 9.

[0033] The working process of this utility model: When the upper die holder 1 opens relative to the lower die holder 8, the punch press moves upward, driving the blanking punch 9 upward. Under the action of the return spring 13, the scrap block 12 continues to apply pressure (side thrust) to the scrap 14 cut from the material 10. When the punch press moves downward, the blanking punch 9 moves downward to cut the material under the action of the upper die holder 1. When the blanking punch 9 touches the material 10, the scrap 14 formed during the punching process enters the force-bearing end face 19 of the scrap block 12 through the guide inclined surface 20, pushing the scrap block 12 backward, so that the scrap block 12 begins to slide along the slide groove 15. At the same time, under the action of the return spring 13, the scrap 14 is always subjected to the side thrust of the scrap block 12 (force-bearing end face 19), ensuring that the scrap 14 will not run upward and always keep the scrap 14 in a horizontal force state, thus achieving the purpose of preventing chip jumping of the product. After the mold closes, the scrap 14 in front is subjected to the downward pressure of the discharge punch 9, and is disengaged from the scrap block 12. It leaves the force-bearing end face 19 from the guide slope 21 and falls down along the discharge groove 16, thus completing the action.

[0034] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
