[0002] In existing stamping technologies, progressive dies are a common type of die. They consist of multiple single-stage processes. By adding positioning pins inside the die and cooperating with a feeder, this type of die achieves precise positioning for each stamping. The working principle of progressive dies is to feed the rolled material from the front end of the die, and after a series of stamping processes, the finished product is output at the tail end. This process is highly automated, eliminating the tedious process of placing and removing products after each stamping, which is traditionally required by manual labor, and greatly improving production efficiency.

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] In this embodiment, the upper limit end can accurately limit the stroke of the upper die during the stamping process, ensuring the positional accuracy of the upper and lower dies when they are closed, and avoiding stamping defects caused by excessive or insufficient stroke. The upper shape cutting end can be precisely cut according to the different shape requirements of the accelerator pedal base bushing. The symmetrically arranged cutting blocks can ensure the symmetry and consistency of the cutting, making the product shape more regular. The upper bending end can realize bending processing of different parts of the product. The upper shaping end can effectively shape the product during the stamping process.

The first lower bending groove 36 is provided, and two first lower bending blocks 35 are symmetrically arranged within the first lower bending groove 36. The second lower bending end is a second lower bending block 37 and a second lower bending groove 38, and the second lower bending block 37 is located within the second lower bending groove 38. The lower shaping end is provided by two lower shaping rollers 39, two lower shaping seats 40, and a lower shaping groove 41. The two lower shaping rollers 39 are arranged on the second lower bending block 37, and the two lower shaping rollers 39 are located within the corresponding lower shaping seats 40. The two lower shaping seats 40 are symmetrically arranged within the lower shaping groove 41. The second product falling end is provided by two second product falling grooves 42, and the two second product falling grooves 42 are symmetrically arranged.

[0026] In this embodiment, the lower limit end and the upper limit end cooperate to more accurately limit the relative position of the upper and lower dies, further improving the mold closing accuracy. The lower outer shape cutting end cooperates with the upper outer shape cutting end to complete the cutting process more accurately, ensuring the flatness and perpendicularity of the cutting surface and improving the cutting quality of the product. The lower bending end and the upper bending end cooperate with the bending end of the upper die to achieve more accurate and stable bending processing, improving the bending quality and efficiency. The lower shaping end and the upper shaping end cooperate with the upper shaping end to dynamically shape the product during the stamping process, making the product shaping effect better and the surface smoother, improving the product quality and appearance. The second product falling end cooperates with the first product falling end to allow the product to fall smoothly from the lower die, ensuring the continuity of production.

[0027] Furthermore, the lower end face of the stripping plate 6 is also provided with a plurality of positioning posts 9, and the plurality of positioning posts 9 are symmetrically arranged in pairs on both sides of the first upper outer shape cutting end, the second upper outer shape cutting end, the third upper outer shape cutting end, the fourth upper outer shape cutting end, the fifth upper outer shape cutting end, the sixth upper outer shape cutting end, the first upper bending end, the first upper step end 7, the second upper bending end, the upper shaping end, the second upper step end 89 and the first product falling end.

[0028] In this embodiment, the positioning post 9 can play a positioning role during the stamping process, ensuring the relative positional accuracy between the stripper plate 6 and the lower template 11, preventing the stripper plate 6 from shifting during stamping, thereby ensuring that each functional end can accurately act on the product, improving the stamping accuracy and stability, and reducing product defects caused by the shift of the stripper plate 6.

[0029] Furthermore, the upper end face of the lower template 11 also has a plurality of positioning holes 14, and the plurality of positioning holes 14 are symmetrically arranged in pairs on both sides of the first lower shape cutting end, the second lower shape cutting end, the third lower shape cutting end, the fourth lower shape cutting end, the fifth lower shape cutting end, the sixth lower shape cutting end, the first lower bending end, the first lower step end 12, the second lower bending end, the lower shaping end, the second lower step end 13 and the second product falling end.

[0030] In this embodiment, the positioning hole 14 and the positioning pin 9 on the stripper plate 6 cooperate with each other, which further enhances the positioning accuracy and stability of the mold. During the assembly and stamping process of the mold, the cooperation between the positioning hole 14 and the positioning pin 9 can ensure accurate alignment between the upper mold and the lower mold, so that each functional end can accurately process the product according to the design requirements, thereby improving the quality and consistency of the product.

[0031] In this invention, the raw material is fed backward at a fixed distance of 27mm each time with the help of a feeder. As the feeder continues to feed, the upper die holder 1 is periodically pressed downward under the drive of the punch press. During the pressing process of the upper die holder 1, the stripper plate 6 set at its upper end contacts the lower die plate 11. The lower end face of the stripper plate 6 has multiple cutting ends, bending ends, shaping ends, and product dropping ends. These structures are closely matched with the corresponding ends of the upper end face of the lower die plate 11 to perform continuous cutting, bending, and shaping operations on the raw material. After multiple feedings and the pressing of the upper die holder 1, the designed accelerator pedal base bushing product is finally formed and discharged from the product dropping end. The whole process is highly automated, which not only improves production efficiency but also ensures the consistency of product quality.
