Description

Technical Field

[0001] The utility model relates to the technical field of stamping die bending, in particular to a stamping die bending structure without abrasion marks. Background Technique

[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that, at room temperature, uses a die installed on a press to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the required parts. When the die is in production, bending is required to achieve the final use purpose. This tool is composed of various parts, and different dies are composed of different parts. It mainly realizes the processing of the outer shape of the article by changing the physical state of the formed material.

[0003] Currently, it is difficult to quickly fix the stamping die according to the die during bending, resulting in low bending efficiency. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a stamping die bending structure without abrasion marks to solve the problem that it is difficult to quickly fix the stamping die according to the die during bending, resulting in low bending efficiency mentioned in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A stamping die bending structure without abrasion marks, including a fixed seat and a stamping head. A spring assembly is fixedly installed on the outer surface of the fixed seat. The output end of the spring assembly is fixedly installed with a connecting seat. The connecting seat is slidably connected to the fixed seat. The outer surface of the connecting seat is rotatably connected with a first folding plate and a second folding plate. Two screw members are threadedly connected to the outer surface of the second folding plate. The outer surfaces of the two screw members are both rotatably connected with mounting plates. A stamping groove is formed on the outer surface of the connecting seat. The stamping head is in fit connection with the stamping groove. Two support frames are fixedly installed on the outer surface of the fixed seat. The output ends of the two support frames are both fixedly installed with connecting members. The two support frames are respectively rotatably connected with the first folding plate and the second folding plate through the connecting members. The two support frames are both slidably connected to the connecting seat.

[0006] Preferably, a sliding groove is formed on the outer surface of the first folding plate. A long screw is threadedly connected to the outer surface of the first folding plate. The outer surface of the long screw is rotatably connected with a fixing plate. A plurality of telescopic springs are fixedly installed on the outer surface of the fixing plate away from the long screw.

[0011] 1. For the structure of the stamping die without grinding marks during bending, the stamping head is controlled to stamp the die placed on the outer surfaces of the first folding plate and the second folding plate.

[0012] 2. For the structure of the stamping die without grinding marks during bending, by rotating the long screw on the outer surface of the first folding plate, the backing plate is driven to slide on the outer surface of the first folding plate to adjust the length of the die to be bent. At the same time, when the die is bent, it is likely to exceed the fixed length. At this time, the telescopic spring retracts, thereby achieving the effect of preventing the die from jamming while ensuring the bending length. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1:

[0021] Please refer to FIGS. 1-5

[0022] A stamping die bending structure without abrasion marks includes a fixed seat 1 and a stamping head 8. A spring assembly 2 is fixedly installed on the outer surface of the fixed seat 1. The output end of the spring assembly 2 is fixedly installed with a connecting seat 3. The connecting seat 3 is slidably connected to the fixed seat 1. The outer surface of the connecting seat 3 is rotatably connected with a first folding plate 6 and a second folding plate 7. Two screw parts 15 are threadedly connected to the outer surface of the second folding plate 7. The outer surfaces of the two screw parts 15 are both rotatably connected with a mounting plate 16. A stamping groove 9 is formed on the outer surface of the connecting seat 3. The stamping head 8 is in fit connection with the stamping groove 9. Two support frames 4 are fixedly installed on the outer surface of the fixed seat 1. The output ends of the two support frames 4 are both fixedly installed with connecting pieces 5. The two support frames 4 are respectively rotatably connected with the first folding plate 6 and the second folding plate 7 through the connecting pieces 5. Both of the two support frames 4 are slidably connected to the connecting seat 3.

[0023] Specifically, by controlling the stamping head 8 to stamp the die placed on the outer surfaces of the first folding plate 6 and the second folding plate 7, in order to prevent the textile die from shifting during stamping, two screw parts 15 are threadedly connected to the outer surface of the second folding plate 7, so that the mounting plates 16 rotatably connected to the outer surfaces of the two screw parts 15 clamp the die, so that when the stamping head 8 bends the die, the shift is reduced, thereby achieving the effect of quickly fixing the die and improving the bending efficiency.

[0024] In the embodiment: Rollers 17 are rotatably connected to the outer surfaces of the first folding plate 6 and the second folding plate 7 close to the stamping groove 9.

[0025] Specifically, rollers 17 are rotatably connected to the outer surfaces of the first folding plate 6 and the second folding plate 7 close to the stamping groove 9. When the stamping head 8 bends the die, the rollers 17 rotate to reduce the creases when the die is bent.

When the stamping head 8 bends the mold, the spring assembly 2 retracts, driving the connecting seat 3 to descend, and the two support frames 4 lift the first folding plate 6 and the second folding plate 7 to bend them, reducing the bending abrasion marks. At the same time, two screw members 15 are threadedly connected to the outer surface of the second folding plate 7, and mounting plates 16 are rotatably connected to the outer surfaces of the two screw members 15. By controlling the two screw members 15 threadedly connected to the outer surface of the second folding plate 7, the mounting plates 16 rotatably connected to the outer surfaces of the two screw members 15 clamp the mold, so that when the stamping head 8 bends the mold, the offset is reduced. Compared with the related art, a stamping die bending structure without abrasion marks provided by the present utility model has the following beneficial effects: Thus, the mold can be quickly fixed, and the bending efficiency can be improved.
