Description

Technical Field

[0001] This utility model is a stamping die that is easy to assemble and disassemble, belonging to the field of stamping die technology. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. Currently, stamping dies are usually fixed on the stamping die for stamping. When the stamping die is damaged, it needs to be replaced. In the existing technology, stamping die heads are usually fixed with fixing bolts. This fixing method makes installation and disassembly inconvenient, thus making it difficult to disassemble and replace the stamping die head, resulting in poor practicality.

[0003] Chinese Patent No. CN221434647U discloses a stamping die with an easy-to-assemble and disassemble stamping die head. By setting a positioning post, the positioning post is engaged with the inside of the cross-shaped clamping plate by a threaded rod. Then, the positioning post positions the positioning plate at the bottom of the stamping die. This reduces the problem of the existing stamping die head body shaking due to the deformation of the spring during installation. It makes the process of disassembling the stamping die head body more convenient. However, there is still room for improvement in the efficiency of its installation and disassembly. There is an urgent need for a stamping die with an easy-to-assemble and disassemble stamping die head to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a stamping die that facilitates the disassembly and assembly of the stamping die head, thereby solving the problems mentioned in the background art. This utility model has a reasonable structure, which uses the limiting slide groove inside the die seat in conjunction with the limiting block to limit and fix the connecting seat, and uses the locking block for secondary limiting, thus facilitating the disassembly and replacement of the stamping head. It is simple and convenient to use and highly practical.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stamping die with an easy-to-assemble and disassemble stamping die head, comprising a die base, a slot, a locking block, an adjusting handle, a limiting block, a rotating connecting shaft, an entry groove, a die head, and a connecting seat. The outer surface of the die base has a slot, the slot has a locking block, the slot has a limiting block, the slot has an adjusting handle, the limiting block has rotating connecting shafts at both ends, the lower end face of the die base has an entry groove, the die head is located below the die base, and the upper end face of the die head has a connecting seat.

[0006] Furthermore, the mold base has a rotating slide groove inside, which is connected to the entry slide groove. The connecting seat slides tightly along the inner wall of the entry slide groove and rotates along the inner wall of the rotating slide groove.

[0007] Furthermore, a limiting slide groove is provided inside the mold base. The limiting slide groove is connected to the entering slide groove through the rotating slide groove, and the connecting seat and the limiting slide groove are engaged with each other.

[0008] Furthermore, the limiting block is semi-elliptical in shape, and a planar end is provided at the lower end of the limiting block. The limiting block is in close contact with the upper surface of the connecting seat through the planar end.

[0009] Furthermore, the limiting block is rotatably connected to the inner wall of the mold base via a rotating connecting shaft, and the adjusting handle is fixedly connected to the limiting block.

[0010] Furthermore, the mold base has a sliding groove inside, the locking block is disposed inside the sliding groove, the upper part of the outer side of the locking block is provided with a guide arc surface, and the lower end of the outer side of the locking block abuts against the upper surface of the adjusting handle.

[0011] Furthermore, a return spring is provided inside the sliding groove, with both ends of the return spring abutting against the locking block and the inner wall of the sliding groove, respectively, and a moving handle is provided on the front end face of the locking block.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a stamping die head that is easy to disassemble and assemble. Because it incorporates a connecting seat, a die seat, a limiting slide groove, a limiting stop block, and a locking block, when the user needs to install the die head, the connecting seat of the die head is first inserted into the die seat through the sliding groove and engaged with the limiting slide groove. Then, the user pulls the adjusting handle downwards, causing the adjusting handle to rotate the limiting stop block. Since the limiting stop block is semi-elliptical and forms a structure similar to an eccentric wheel, its relatively longer flat end abuts tightly against the upper surface of the connecting seat during rotation, thus restricting the vertical movement of the connecting seat. Simultaneously, the lower surface of the locking block abuts against the upper surface of the adjusting handle, thereby limiting the adjustment handle and preventing it from rotating. This fixes the position of the connecting seat and the die head. This design is simple and convenient to use, greatly optimizing the disassembly and installation process, facilitating the disassembly and replacement of the stamping die head, and is highly practical.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-6 This utility model provides a technical solution: a stamping die with an easy-to-install and disassemble stamping die head 8, including a die base 1, a slot 2, a locking block 3, an adjusting handle 4, a limiting block 5, a rotating connecting shaft 6, an entry groove 7, a die head 8, and a connecting seat 9. The outer surface of the die base 1 has a slot 2, the slot 2 has a locking block 3, the slot 2 has a limiting block 5, the slot 2 has an adjusting handle 4, the limiting block 5 has a rotating connecting shaft 6 at both ends, the lower end face of the die base 1 has an entry groove 7, the die head 8 is located below the die base 1, and the upper end face of the die head 8 is located on the connecting seat 9. This design solves the problem that the die head of the original stamping die is inconvenient to install, disassemble, and replace.

[0016] As the first embodiment of this utility model: The mold base 1 has a rotating slide groove 71 inside, which is connected to the entry slide groove 7. The connecting seat 9 slides tightly along the inner wall of the entry slide groove 7. The connecting seat 9 can slide along the entry slide groove 7 and eventually enter the interior of the rotating slide groove 71. The connecting seat 9 rotates along the inner wall of the rotating slide groove 71. The connecting seat 9 disengages from the entry slide groove 7 by rotating inside the rotating slide groove 71. Therefore, when the connecting seat 9 enters the rotating slide groove 71, it cannot move in the vertical direction. Similarly, when the connecting seat 9 does not reach the deepest point of the entry slide groove 7, it can only move in the vertical direction and cannot rotate. The mold base 1 has a limiting slide groove 72 inside. The limiting slide groove 72 is connected to the entry slide groove 7 through the rotating slide groove 71. The connecting seat 9 is engaged with the limiting slide groove 72. The connecting seat 9 can enter the mold base 1 through the entry slide groove 7 and rotate 90 degrees inside the rotating slide groove 71 before engaging with the limiting slide groove 72. When the connecting seat 9 is inside the limiting slide groove 72, it cannot rotate and can only slide in the vertical direction. The limiting block 5 is semi-elliptical and has a flat end 51 at its lower end. The limiting block 5 is in close contact with the upper surface of the connecting seat 9 through the flat end 51. The limiting block 5 and its flat end 51 can fill the movement space of the connecting seat 9 inside the limiting slide groove 72, so that the connecting seat 9 cannot move, thereby achieving the purpose of limiting.

[0017] As a second embodiment of this utility model: the limiting block 5 is rotatably connected to the inner wall of the mold seat 1 via the rotating connecting shaft 6. This design allows the limiting block 5 to rotate freely around the rotating connecting shaft 6. Since the limiting block 5 is semi-elliptical and its whole is eccentric, during the rotation of the limiting block 5, the end that is relatively far from the center will move continuously until its flat end 51 contacts the upper surface of the connecting seat 9. The adjusting handle 4 is fixedly connected to the limiting block 5. The adjusting handle 4 can drive the limiting block 5 to rotate. Under the action of the rotating connecting shaft 6, the limiting block 5 forms a structure similar to an eccentric wheel, thereby abutting and limiting the connecting seat 9, thus preventing the connecting seat 9 from moving in the vertical direction. The mold base 1 has a sliding groove 33 inside, and a locking block 3 is set inside the sliding groove 33. The upper part of the outer side of the locking block 3 is provided with a guide arc surface 31. The lower end of the outer side of the locking block 3 abuts against the upper surface of the adjusting handle 4. The locking block 3 can limit the adjusting handle 4. A return spring 34 is provided inside the sliding groove 33. The two ends of the return spring 34 abut against the locking block 3 and the inner wall of the sliding groove 33, respectively. A moving handle 32 is provided on the front end face of the locking block 3. The return spring 34 can help the locking block 3 to return to its original position. The moving plate makes it easy for the user to adjust the position of the locking block 3.

[0018] As a second embodiment of this utility model: When the user needs to install the mold head 8, first insert the connecting seat 9 of the mold head 8 into the mold base 1 through the inlet slide 7, then rotate it 90 degrees inside the rotating slide 71, and finally engage with the limiting slide 72. At this time, the connecting seat 9 cannot rotate inside the limiting slide 72, but can only move in the vertical direction. Then, the user turns the adjusting handle 4 downward, so that the adjusting handle 4 drives the limiting block 5 to rotate. Since the limiting block 5 has a structure similar to an eccentric wheel, during its rotation, the relatively longer flat end 51 of it tightly abuts against the upper surface of the connecting seat 9, thereby limiting the connection. The connecting seat 9 has the ability to move in the vertical direction. At the same time, when the adjusting handle 4 is rotated, the adjusting handle 4 will press the guide arc surface 31 of the locking block 3. Under the action of the guide arc surface 31, the locking block 3 will retract into the sliding groove 33 and compress the return spring 34. When the adjusting handle 4 is fully rotated to the bottom, the return spring 34 releases its elastic potential energy and drives the locking block 3 to return to its original position. While the locking block 3 moves outward, the lower surface of the locking block 3 abuts against the upper surface of the adjusting handle 4, thereby limiting the adjusting handle 4 and preventing the adjusting handle 4 from rotating, thus fixing the position of the connecting seat 9 and the mold head 8. Similarly, when the mold head 8 needs to be disassembled, the user first pulls the moving handle 32. The moving handle 32 moves the locking block 3 together, causing the locking block 3 to retract into the sliding groove 33. At the same time, the return spring is compressed, and the lower surface of the locking block 3 no longer abuts against the upper surface of the adjusting handle 4, thereby releasing the adjusting handle 4. Then, the user rotates the adjusting handle 4, which causes the limiting block 5 to rotate around the rotating connecting shaft 6, so that the flat end 51 of the limiting block 5 disengages from the upper surface of the connecting seat 9 and no longer abuts against the upper surface of the connecting seat 9. The surfaces are brought into contact until the limiting block 5 rotates 90 degrees, so that the shortest side of the limiting block 5 corresponds to the upper surface of the connecting seat 9. At this time, the limiting block 5 no longer blocks the connecting seat 9 from moving up and down inside the limiting slide groove 72. Then, the connecting seat 9 is moved upward along the inner wall of the limiting slide groove 72 until it enters the rotating slide groove 71. Then, it rotates inside the rotating slide groove 71, so that it rotates from one end of the rotating slide groove 71 to the other end and comes into the entry slide groove 7. Finally, it slides vertically out of the mold seat along the inner wall of the entry slide groove 7, thus completing the disassembly of the mold head.
