Common clamps on the market are made by joining two halves of the clamp together. Both halves are semi-circular rings, and clamps are generally made by stamping.

[0003] During production, the size of the clamp mold corresponds to that of the clamp. The mold is usually fixed with bolts, making it difficult to disassemble and replace. After stamping, the clamp will be stuck with the mold, making it difficult to remove the clamp, which is inconvenient to use. Therefore, we propose a bending mold assembly for clamp production.

[0013] 1. This bending die assembly for producing clamps features a locking structure. During installation, the die body is inserted into slot one, and the throttle one is rotated to rotate the threaded rod one. The threaded rod one engages with the threaded groove one, causing the insert rod to move and be inserted into slot two. At the same time, the limiting block one moves with the threaded rod one, causing the pressure plate to move. After the insert rod is inserted into slot two, the pressure plate is pressed against the surface of the die body by a spring, thereby installing the die body on the base.

[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 One embodiment provided by this utility model:

[0023] A bending die assembly for producing clamps includes a base 1. The top of the base 1 has a slot 11, the inner wall of the slot 11 has a groove 12, and the interior of the groove 12 has a groove 13. The base 1 has an engagement structure 2, which includes a handle 21. A threaded rod 22 is fixedly connected to the surface of the handle 21. A limit block 23 is fixedly connected to the surface of the threaded rod 22. A rod 24 is fixedly connected to the surface of the limit block 23. A rotating block 25 is sleeved on the outer side of the limit block 23. A spring 26 is fixedly connected to the surface of the mold body 3. A pressure plate 27 is fixedly connected to one end of the spring 26. The mold body 3 is inserted into the slot 11. A slot 2 31 is opened on the surface of the mold body 3. An unloading structure 4 is set inside the mold body 3. The unloading structure 4 includes a handle 2 41. A rotating rod 42 is fixedly connected to the surface of the handle 2 41. Two sets of bevel gears 1 43 are symmetrically fixedly connected to the surface of the rotating rod 42. Bevel gears 2 44 mesh with the surface of bevel gears 1 43. A threaded rod 2 45 is fixedly connected to the top of bevel gears 2 44. The mold body 3 is fixedly connected to a limiting block 46, and a sliding post 47 is movably connected to the outer side of the threaded rod 45. A locking structure 2 is provided. During installation, the mold body 3 is inserted into the slot 11. Turning the handle 21 rotates the threaded rod 22, which engages with the threaded groove, causing the insert rod 24 to move and insert into the slot 21. At the same time, the limiting block 23 moves with the threaded rod 22, causing the pressure plate 27 to move. After the insert rod 24 is inserted into the slot 21, the pressure plate 27 is pressed against the surface of the mold body 3 by the spring 26, thereby pressing the mold body 3. The body 3 is installed on the base 1, making it easy to install and disassemble the mold body 3 and replace it. A material unloading structure 4 is provided. After stamping, the second throttle 41 is turned to drive the rotating rod 42 to rotate. The first bevel gear 43 and the second bevel gear 44 on the rotating rod 42 mesh with each other, thereby driving the second threaded rod 45 to rotate. Through the cooperation between the second threaded rod 45 and the second threaded groove in the sliding column 47, the sliding column 47 is driven to move upward, thereby lifting the clamp and separating it from the mold body 3, making it easy to remove the clamp after stamping. It is convenient to use.

[0024] Furthermore, the radius of the limiting block 23 is larger than the radius of the insert rod 24 and the threaded rod 22. The rotating block 25 has a circular groove inside, and the limiting block 23 is rotatably connected in the circular groove. When the threaded rod 22 rotates and drives the insert rod 24 to move, the rotating block 25 and the threaded rod 22 can be rotated separately and independently through the cooperation of the limiting block 23 and the circular groove. At the same time, the rotating block 25 can also move with the threaded rod 22, which facilitates the abutment of the pressure plate 27.

[0025] Furthermore, the spring 26 is sleeved on the outside of the insert rod 24, and the surface of the pressure plate 27 is provided with a circular groove 2. The pressure plate 27 is slidably connected to the surface of the insert rod 24 through the circular groove 2. The surface of the pressure plate 27 is provided with a rubber pad layer. When the limiting block 1 23 moves with the threaded rod 1 22, it drives the pressure plate 27 to move. After the insert rod 24 is inserted into the slot 2 31, the spring 26 abuts the pressure plate 27 against the surface of the mold body 3, making the connection between the mold body 3 and the base 1 more stable. The rubber pad layer increases the friction between the mold body 3 and the base 1 and provides protection for the mold body 3.

[0026] Furthermore, the cross-section of slide groove 12 is square, and pressure plate 27 is slidably connected in slide groove 12. The cross-section of slide groove 23 is circular, and rotating block 25 is slidably connected in slide groove 23. Threaded groove 1 is opened on the surface of base 1, and threaded rod 22 is rotatably connected in threaded groove 1. Through the cooperation between pressure plate 27 and slide groove 12 and the cooperation between limiting block 23 and circular groove 1, the rotation of pressure plate 27 is prevented.

[0027] Furthermore, the bottom of the sliding column 47 is provided with a second threaded groove, and the second threaded rod 45 matches the second threaded groove. The first bevel gear 43 and the second bevel gear 44 on the rotating rod 42 mesh with each other, thereby driving the second threaded rod 45 to rotate. Through the cooperation between the second threaded rod 45 and the second threaded groove in the sliding column 47, the sliding column 47 is driven to move upward.

[0028] Furthermore, the radius of the second limiting block 46 is larger than the radius of the second threaded rod 45. The top of the second threaded groove is provided with a third sliding groove. The second limiting block 46 is slidably connected in the third sliding groove. Through the cooperation between the second limiting block 46 and the third sliding groove, the maximum movement distance of the sliding column 47 is limited, preventing it from detaching from the second threaded rod 45.

[0029] Furthermore, a square groove 2 is provided on the top of the mold body 3, and the sliding column 47 is slidably connected in the square groove 2. The sliding column 47 moves upward from the square groove 2, thereby lifting the clamp and separating it from the mold body 3. When the sliding column 47 moves down to the lowest point, the top of the sliding column 47 is flush with the top of the mold body 3.

[0030] Working principle: During installation, insert the mold body 3 into slot 11, rotate the handle 21 to rotate the threaded rod 22, which engages with the threaded groove 1, causing the insert rod 24 to move and insert into slot 31. At the same time, the limiting block 23 moves with the threaded rod 22, causing the pressure plate 27 to move. After the insert rod 24 is inserted into slot 31, the pressure plate 27 is pressed against the surface of the mold body 3 by the spring 26, thus installing the mold body 3 on the base 1. Disassembly can be performed by reversing the operation. After stamping is completed, rotate the handle 41 to rotate the rotating rod 42. The bevel gear 43 and bevel gear 44 on the rotating rod 42 mesh with each other, thus causing the threaded rod 45 to rotate. Through the engagement of the threaded rod 45 with the threaded groove 2 in the sliding column 47, the sliding column 47 is moved upward, thus lifting the clamp and separating it from the mold body 3, making it easy to remove the clamp and use.
