[0002] Blanking dies are used to shape and cut parts in stamping production. Their primary function is to separate materials, and within this context, they can be categorized in various ways. Based on the nature of the process, blanking dies can be divided into blanking dies, punching dies, cutting dies, trimming dies, and fine-blanking dies.

[0003] Referring to CN216679777U, the present invention provides a die for synchronously processing stator product components, comprising an upper die and a lower die. The upper die cooperates with the lower die to punch a sheet of material. The lower die is provided with a die fixing plate, a material guide plate, and a blanking structure. The die fixing plate is sequentially arranged from left to right on a first product die, a second product die, and a third product die. The die fixing plate also sequentially arranges N groups of first, second, and third product dies from top to bottom. In the present invention, the first, second, and third product dies are arranged on a single die fixing plate. This allows for the rational allocation of dies for various product types to the same die fixing plate, effectively utilizing excess sheet material. Furthermore, N groups of first, second, and third product dies can be arranged on the die fixing plate. This effectively utilizes sheet material and improves production efficiency during punching and shearing production.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following is combined with Figure 1-5 The utility model is described in further detail.

[0034] The utility model discloses a synchronously processed punching die. It includes an upper die 2 and a lower die 8. The lower die 8 is arranged below the upper die 2. An upper die base 5 is arranged above the upper die 2. Cylinders 2 4 for driving the upper die 2 to rise and fall are symmetrically installed on both sides of the upper die base 5. When the cylinders 2 4 are activated, they expand or contract, driving the upper die 2 to move downward or upward. The piston rod end of the cylinder 2 4 is fixedly connected to the top of the upper die 2. A cutting die 6 is arranged inside the upper die 2. A through hole is provided on the upper die 2 for the cutting die 6 to slide up and down. A cylinder 1 3 for the cutting die 6 to move up and down is installed on the top of the upper die 2. A reserved through cavity for the cutting die 6 to move up and down is provided in the middle position of the upper die 2. The piston rod end of the cylinder 1 3 is fixedly connected to the top of the cutting die 6. When the cylinder 1 3 is activated, it expands or contracts, driving the cutting die 6 to move downward or upward. A rectangular through hole for the cylinder 1 3 to move up and down is provided in the middle position of the upper die base 5. After the cutting die 6 moves up, the upper die 2 moves up, and the cylinder 1 3 moves up to the upper die base 5 away from the upper side of the upper die 2 (not the cylinder rod end of the cylinder 1 3 ).

[0035] Reference Figure 1 and Figure 4 The lower mold 8 has positioning grooves 14 at one end and one side. A positioning plate 10 slides through the positioning grooves 14 on the lower mold 8. A second spring 15 is fixed to the bottom end of the positioning plate 10, and the bottom end of the second spring 15 is fixedly connected to the lower mold 8. The positioning groove 14 is exposed on the outer wall of the support platform 1, which facilitates welding the second spring 15 to the sound insulation cover 7 using a welding machine. The positioning plate 10 forms a reset structure with the second spring 15. When the positioning plate 10 is squeezed by the upper mold 2, the second spring 15 contracts, which does not affect the impact of the upper mold 2 on the sheet metal.

[0036] Reference Figure 1-3 The bottom end of the lower mold 8 is fixed with a supporting platform 1, and a waste outlet 9 is opened in the supporting platform 1 and communicates with the lower mold 8. The cut waste flows out through the waste outlet 9. The waste outlet 9 is arranged at an angle in the supporting platform 1. The inclined setting of the waste outlet 9 prevents waste from accumulating directly under the supporting platform 1.

[0037] Reference Figure 1 、 Figure 3 and Figure 5 A soundproof cover 7 is provided on the outside of the upper mold 2, and the soundproof cover 7 is used to block the contact surface between the upper mold 2 and the waste material, which is conducive to isolating the sound. And the cross-section of the soundproof cover 7 is larger than the cross-section of the lower mold 8. A connecting rod 11 is fixed to the top of the upper mold 2, and the connecting rod 11 runs through the soundproof cover 7. The connecting rod 11 ensures that the soundproof cover 7 moves up and down smoothly; wherein, a spring 12 is fixed to the top of the soundproof cover 7, and the top of the spring 12 and the bottom of the connecting rod 11 near the top are in conflict, and the spring 12 is sleeved on the outside of the connecting rod 11. When the soundproof cover 7 contacts the lower mold 8 near the bottom, it does not affect the upper mold 2 from continuing to move down close to the lower mold 8; in addition, a rubber pad 13 is provided on the inner wall of the soundproof cover 7, and the bottom of the rubber pad 13 is located at the bottom end of the soundproof cover 7. The rubber pad 13 has a soundproofing effect on noise to a certain extent.

[0038] The implementation principle of the synchronous processing punching die of the utility model is:

[0039] First, the sheet is placed on the lower die 8, with both sides of the sheet contacting the positioning plate 10. Cylinder 2 (4) activates the upper die 2, which moves downward toward the lower die 8 to impact the sheet. Cylinder 1 (3) is then activated, driving the cutting die 6 downward to cut the sheet. The cut waste flows out through the waste outlet 9. After the upper die 2 contacts the sheet, a soundproofing hood 7 encloses the lower die 8 and upper die 2, providing sound insulation and reducing noise. Finally, the upper die 2 moves upward to remove the finished sheet from the lower die 8, completing the operation of the blanking die.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
