[0002] A bending die is a tool used for bending sheet metal, commonly found in sheet metal processing, automobile manufacturing, and home appliance and furniture industries. A wide variety of materials are used in the production of bending dies, including cemented carbide, steel-bonded cemented carbide, zinc-based alloys, low-melting-point alloys, aluminum bronze, polymer materials, carbon tool steel, and low-alloy tool steel.

[0003] However, the existing bending die structure has the following problems when used:

[0004] Different usage requirements lead to different bending shapes for sheet metal, and different gaps in the lower die can change the processed shape of the sheet metal. Therefore, a device is needed that can easily adjust the gap of the lower die. However, the existing bending die structure is not convenient for adjusting the gap of the lower die according to the requirements, which makes it difficult for the device to process the sheet metal into different shapes, thus reducing the practicality of the device.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing bending die structure. Utility Model Content

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-5 , the present invention provides a technical solution: a bending die structure with adjustable clearance, including a base 1, a support frame 2, an electric telescopic rod 3, an inner upper die 4, a limit frame 5, an upper die attachment 6, a knob 7, a double-headed servo motor 8, an active rod 9, a base 10, an adjusting sleeve 11, a transmission rod 12, a transmission frame 13, a lower die 14 and a sprocket mechanism 15. The upper surface of the base 1 is fixedly connected with a support frame 2, and both ends of the upper surface of the support frame 2 are provided with electric telescopic rods 3, and the lower end of the output shaft of the electric telescopic rod 3 is fixedly connected with an inner upper die 4. A double-headed servo motor 8 is arranged on the lower surface of the base 1, and active rods 9 are fixed at both ends of the output shaft of the double-headed servo motor 8. The upper surface of the base 1 above the active rod 9 is fixedly connected with a base 10. The inner wall of the base 10 is movably installed with an adjusting sleeve 11, and the inner wall of the adjusting sleeve 11 is movably connected with a transmission rod 12, and the end of the transmission rod 12 is fixedly provided with a transmission frame 13, and the side of the transmission frame 13 is fixedly connected with a lower die 14.

[0025] A limit frame 5 is fixedly installed at the end of the upper surface of the inner upper die 4, and the inner wall of the limit frame 5 is movably connected with an upper die attachment 6, and a knob 7 is movably arranged on the inner wall of the end of the upper die attachment 6 away from the limit frame 5, which is convenient for bending the sheet material by the simultaneous downward movement of the inner upper die 4 and the upper die attachment 6.

[0026] The cross-sectional shape of the upper die attachment 6 is set to a "C" shape, and the lower surface of the upper die attachment 6 is on the same horizontal plane as the lower surface of the inner upper die 4, which is convenient for the upper die attachment 6 to be stably positioned on the inner upper die 4 and ensure the flatness of the bottom of the sheet material after bending.

[0027] The upper die attachment 6 is respectively slidably connected with the inner upper die 4 and the limit frame 5, which is convenient for the user to move the upper die attachment 6 for disassembly and assembly of the upper die attachment 6.

[0028] The knob 7 is threaded to the inner upper mold 4 and the upper mold attachment 6 respectively, so that the user can rotate the knob 7 to disengage the knob 7 from the inner upper mold 4, thereby making it convenient for the user to remove the upper mold attachment 6.

[0029] The outer wall of the end of the active rod 9 is connected to the outer wall of the end of the adjusting sleeve 11 through the sprocket mechanism 15, so that when the dual-head servo motor 8 drives the active rod 9, the adjusting sleeve 11 rotates at the same time.

[0030] The adjusting sleeve 11 and the base 10 form a rotating structure, which facilitates the stable rotation of the adjusting sleeve 11 relative to the base 10.

[0031] The adjusting sleeve 11 and the transmission rod 12 are threadedly connected. The lower mold 14 and the base 1 are slidably connected. When the adjusting sleeve 11 rotates, the transmission rod 12 moves relative to the adjusting sleeve 11, thereby driving the transmission frame 13 to move. This causes the transmission frame 13 to drive the lower mold 14 to slide relative to the base 1, thus allowing the lower mold 14 to move stably and adjust the gap of the lower mold 14.

[0032] Working principle: When using this adjustable gap bending die structure, firstly as follows... Figure 1-5As shown, the user places the sheet metal to be processed onto the lower mold 14. Then, the user activates the electric telescopic rod 3, which drives the inner upper mold 4 downwards. At this time, the inner upper mold 4 and the upper mold attachment 6 move downwards simultaneously, pressing the sheet metal into the cavity formed by the lower mold 14 and the base 1, thus completing the bending of the sheet metal. When the user needs to bend the sheet metal into different shapes, the user controls the electric telescopic rod 3 to drive the inner upper mold 4 upwards. The inner upper mold 4 then resets. Next, the user rotates the knob 7, which disengages from the inner upper mold 4. Then, the user moves the upper mold attachment 6, causing it to disengage from the limit frame 5. The user then removes the upper mold attachment 6, thus completing the disassembly of the upper mold attachment 6. Finally, the user activates the dual-head servo motor 8, which drives the drive rod 9 to rotate. The drive rod 9 then rotates via a sprocket mechanism. 15 drives the adjusting sleeve 11 to rotate relative to the base 10, then the transmission rod 12 moves relative to the base 10, then the transmission rod 12 drives the transmission frame 13 to move, then the transmission frame 13 drives the lower mold 14 to slide relative to the base 1. At this time, the lower mold 14 moves towards each other, thereby adjusting the gap of the lower mold 14. After the position of the lower mold 14 is adjusted, the user places the sheet material on the lower mold 14, and then operates the electric telescopic rod 3 as described above to make the inner upper mold 4 move down. At this time, the inner upper mold 4 presses the sheet material into the cavity formed by the lower mold 14 and the base 1. However, since the inner upper mold 4 has removed the external upper mold attachment 6, and the gap of the lower mold 14 changes, the bending shape of the sheet material changes. Therefore, the device can easily adjust the gap of the lower mold 14 according to the requirements, so as to facilitate the device to process the sheet material into different shapes, thus improving the practicality of the device.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
