Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a double-punch cutting block punch structure. Background Technology

[0002] In modern industrial manufacturing, stamping dies are a key forming tool widely used in many industries such as automotive, electronics, home appliances, and aerospace. They can process metal or non-metal sheets into parts of various shapes using the pressure of a stamping press, offering advantages such as high production efficiency, stable product quality, and good machining precision.

[0003] Traditional stamping dies mostly employ a single-punch design, producing only one product per stamping operation. In large-scale production scenarios, frequent stamping operations are required, which not only increases production time but also limits overall production efficiency. Therefore, we propose a dual-punch block structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a double-punch block punch structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a double-punch block punch structure, including a lower die assembly installed on the punch press worktable and an upper die assembly installed on the punch press slide rail body. The upper die assembly slides outside the lower die assembly. Two sets of male dies are installed on the top of the lower die assembly, and the two sets of male dies have a rotationally symmetrical structure to realize a double-punching structure.

[0006] Furthermore, it also includes a strip material disposed between the lower die assembly and the upper die assembly. Two sets of lower die cutting blocks are symmetrically installed on the side of the lower die assembly and below the strip material, and two sets of upper die cutting blocks are installed on the side of the upper die assembly and above the strip material, with the structures of the two sets of lower die cutting blocks and the two sets of upper die cutting blocks corresponding to each other.

[0007] Furthermore, the lower mold assembly includes a lower mold base, two sets of male molds are mounted on the lower mold base, a movable plate is provided above the lower mold base, the movable plate is slidably connected to the outside of the two sets of male molds, and multiple sets of springs are provided between the lower mold base and the movable plate.

[0008] Furthermore, multiple sets of ejector pins are provided above the lower mold base and outside the two sets of male molds. A spring is provided between the lower mold base and each set of ejector pins. The movable plate is slidably connected to the outside of the multiple sets of ejector pins.

[0009] Furthermore, two sets of limiting plates are symmetrically installed on the top of the movable plate, and multiple sets of guide pillars are installed at the edge of the lower mold base.

The bottom cavity of the upper mold base is provided with two sets of striking plates, and springs are installed between the two sets of striking plates and the upper mold base.

[0011] Furthermore, the bottom of both sets of striking plates is connected to an inner ejector plate via a connecting rod.

Multiple sets of punches are installed at the bottom of the pad, and each set of punches is slidably connected to the two sets of inner ejector plates. Beneficial effects

[0012] This invention provides a double-punch block punch structure. Compared with the prior art, it has the following advantages:

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution for a double-cutting block punch structure: a double-cutting block punch structure includes a lower die assembly 1, an upper die assembly 2, a male die 3, a strip material 4, two sets of lower die cutting blocks 5 and two sets of upper die cutting blocks 6. Specifically, the two sets of male dies 3 are installed on the lower die assembly 1 in a rotationally symmetrical structure. When the lower die assembly 1 and the upper die assembly 2 are stamping, the two sets of male dies 3 can simultaneously perform stamping operations on the strip material 4, thereby realizing the production of two products in one stamping, doubling the efficiency. The two sets of lower die cutting blocks 5 and the two sets of upper die cutting blocks 6 are symmetrically arranged on the sides of the lower die assembly 1 and the upper die assembly 2, respectively, so as to cut the stamped strip material 4, avoiding the impact of the strip material 4 being too long or irregular in shape on subsequent production, and improving the stability and reliability of the entire production process.

[0023] The lower mold assembly 1 includes a lower mold base 11, a movable plate 12, multiple sets of springs 13, multiple sets of ejector pins 14, springs 15, two sets of limiting plates 16, and multiple sets of guide pillars 17. Specifically, two sets of male molds 3 are fixed on the lower mold base 11, and the movable plate 12 is slidably connected to the outside of the two sets of male molds 3. Thus, during stamping, the two sets of male molds 3 are in contact with the bottom of the strip 4. The upper mold assembly 2 applies pressure to the strip 4, the movable plate 12, and the multiple sets of ejector pins 14, causing the multiple sets of springs 13 and the multiple sets of springs 15 to compress. Thus, the male mold 3 enters the upper mold assembly 2 to complete the product stamping. After stamping, the multiple sets of springs 13 and the multiple sets of springs 15 push the movable plate 12 and the multiple sets of ejector pins 14 to move upward to eject the strip 4, and place the strip 4 above the male mold 3.

[0024] The upper mold assembly 2 includes an upper mold base 21, a backing plate 22, an upper template 23, a punching plate 24, springs 25, inner ejector plates 26, and punches 27. Specifically, two sets of inner ejector plates 26 slide on the upper template 23. The two sets of inner ejector plates 26 have a rotationally symmetrical structure, and the positions of the two sets of inner ejector plates 26 and the two sets of male molds 3 correspond to each other. The two sets of inner ejector plates 26 and the two sets of punching plates 24 are connected by connecting rods, and the two sets of connecting rods slide inside the backing plate 22. After the two sets of inner ejector plates 26 come into contact with the strip 4, they move upward. The two sets of backing plates 22 compress the two sets of springs 25, so that multiple sets of punches 27 punch the strip 4, and the two sets of male molds 3 enter the upper template 23 to complete the product stamping. After the stamping is completed, the two sets of springs 25 push the two sets of backing plates 22 and the two sets of inner ejector plates 26 downward to push the product out and complete the stripping.

[0025] Please refer to Figure 6 After the strip 4 is stamped by the two sets of male molds 3, the material grooves form a rotationally symmetrical structure and are spaced at a certain distance. Then, after multiple stampings, the material grooves are distributed in rows.

[0026] In actual use, the double punching block punch structure drives the upper die assembly 2 to move downward in a straight line. After the two sets of inner ejector plates 26 contact the strip 4, the two sets of inner ejector plates 26 and the two sets of pads 22 compress the two sets of springs 3 25, so that the upper die plate 23 and the two sets of male dies 3 fix the strip 4. The upper die assembly 2 continues to move downward, the two sets of male dies 3 punch the strip 4, and multiple sets of punches 27 punch the strip 4. The movable plate 12 and multiple sets of ejector pins 14 move downward under pressure, compressing multiple sets of springs 1 13 and multiple sets of springs 2 15, so that the two sets of male dies 3 enter the upper die plate 23 to complete the product punching.

[0027] After the stamping is completed, the main body of the press slide rail drives the upper die assembly 2 to move upward in a straight line. Multiple sets of spring 13 and multiple sets of spring 25 extend and push the movable plate 12 and multiple sets of ejector pins 14 to move upward to eject the material strip 4, and place the material strip 4 above the two sets of male dies 3. Spring 3 25 pushes the pad plate 22 and the inner stripper plate 26 to move downward, pushing the product out to complete the stripping, thereby realizing the production of two products in one stamping, doubling the efficiency;

[0028] During repeated stamping, the strip 4 moves to one side of the mold, and then during the stamping of the lower mold assembly 1 and the upper mold assembly 2, the two sets of lower mold cutting blocks 5 and the two sets of upper mold cutting blocks 6 cut the stamped strip 4.
