[0002] A secondary angle bending die is a specialized die used in the processing of sheet metal, primarily for bending sheet metal at specific angles. Through a well-designed die structure and working components, the sheet metal undergoes plastic deformation within the die under the action of equipment such as a press, thereby obtaining the bending angle and shape that meet the product design requirements. During the sheet metal bending process, to avoid reducing processing speed due to excessive positioning time, a rapid positioning structure is required.

[0003] The quick positioning structure of the secondary angle bending die is a component designed to achieve rapid and accurate positioning of the workpiece. In the past, operators usually had to manually position and process the sheet metal. This method relied on experience and feel, and it was difficult to guarantee the accuracy of positioning each time, thus affecting the processing of the sheet metal. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a quick positioning structure for a secondary angle bending die, including a worktable 1, a lower die base 2 fixedly connected to the upper surface of the worktable 1, an installation block 3 provided inside the lower die base 2, a die 4 rotatably connected to the outer wall of the installation block 3, a motor 5 fixedly connected to the lower surface of the worktable 1, the output end of the motor 5 passing through the interior of the worktable 1 and fixedly provided with a transmission shaft 6, a gear 7 fixedly connected to the outer wall of the transmission shaft 6, a gear plate 8 meshing with the tooth end of the gear 7, an L-shaped frame 9 fixedly connected to the outer wall of the gear plate 8, a positioning plate 10 fixedly connected to the outer wall of the L-shaped frame 9, a slide rail 11 fixedly connected to the lower surface of the positioning plate 10, the outer wall of the slide rail 11 slidably connected to the interior of the lower die base 2, a fixing frame 12 fixedly connected to the upper surface of the worktable 1, an upper die base 14 slidably connected to the outer wall of the fixing frame 12, and a drive assembly provided inside the fixing frame 12;

[0025] Specifically, the inner wall of the die 4 rotates against the outer wall of the mounting block 3, and the outer wall of the die 4 fits against the inner wall of the mounting block 3, supporting and limiting the rotation of the die 4. Lower die bases 2 are provided on both sides of the worktable 1, and the upper die base 14 is driven by the drive assembly to extrude the plate on the upper surface of the lower die base 2. The plate is bent by the limiting effect of the lower die bases 2 on both sides. The movement of the upper die base 14 is restricted by the fixing frame 12. The transmission shaft 6 is driven by the motor 5, and the gear 7 drives the toothed plate 8 and the L-shaped frame 9, so that the positioning plate 10 clamps or releases the plate. When the plate is extruded and bent, the positioning plate 10 clamps and limits the initial bending of the plate. After the bending is completed, the positioning plate 10 no longer clamps the plate and slides inside the lower die base 2 via the slide rail 11, thus restricting the movement of the positioning plate 10.

[0026] Reference Figure 1 The drive assembly includes a hydraulic rod 13, the outer wall of which is fixedly connected to the inside of the fixed frame 12, and the output end of the hydraulic rod 13 is fixedly connected to the inside of the upper mold base 14.

[0027] Specifically, by activating the hydraulic rod 13, the upper mold base 14 is driven, thereby causing the upper mold base 14 to squeeze or release the plate, and the fixing frame 12 achieves the effect of fixing the hydraulic rod 13.

[0028] Reference Figure 2 and Figure 3 The lower surface of the mounting block 3 is set on the upper surface of the worktable 1. The outer wall of the die 4 is fixedly connected to the tension spring 15. The outer wall of the tension spring 15 is fixedly connected to the outer wall of the mounting block 3. The top end of the drive shaft 6 is rotatably connected to the inside of the worktable 1. The outer wall of the L-shaped frame 9 is slidably connected to the inside of the worktable 1.

[0029] Specifically, the workbench 1 supports the mounting block 3. Short rods are provided on the outer walls of both the mounting block 3 and the die 4, so that the rotation of the die 4 is reset by the tension spring 15. The rotation of the transmission shaft 6 is supported by the inside of the workbench 1, and the movement of the L-shaped frame 9 is also restricted.

[0030] Reference Figure 3 and Figure 4The mounting block 3 has a sliding rod 16 inside, a T-shaped frame 17 fixedly connected to the outer wall of the sliding rod 16, and a hollow block 18 slidably connected to the outer wall of the T-shaped frame 17. The outer wall of the hollow block 18 is fixedly connected to the inside of the mounting block 3. A spring 19 is fixedly connected to the outer wall of the T-shaped frame 17, and the outer wall of the spring 19 is fixedly connected to the inner wall of the hollow block 18. The outer wall of the hollow block 18 is slidably connected to the inside of the mounting block 3. A connecting plate 20 is rotatably connected to the outer wall of the T-shaped frame 17, and a fixed seat 21 is rotatably connected to the inside of the connecting plate 20. The outer wall of the fixed seat 21 is slidably connected to the inner wall of the mounting block 3. A limit rod 22 is slidably connected inside the fixed seat 21, and both ends of the limit rod 22 are fixedly connected to the inner wall of the hollow block 18. A square block 23 is fixedly connected to the outer wall of the fixed seat 21. The outer wall of the square block 23 penetrates the inside of the hollow block 18 and is slidably connected to the inside of the lower mold base 2.

[0031] Specifically, a short rod is provided on the left outer wall of the mounting block 3 for sliding into the interior of the lower mold base 2 to position and prevent shaking during the installation of the mounting block 3. Two T-shaped frames 17 and their connecting structures are provided inside the mounting block 3. By pulling the slide rod 16, the T-shaped frames 17 on both sides are synchronously driven. The interior of the hollow block 18 restricts the movement of the T-shaped frames 17. The interior of the mounting block 3 restricts the movement of the slide rod 16. Short rods are provided inside both the T-shaped frames 17 and the fixed base 21 for the transmission of the connecting plate 20. The elastic force of the spring 19 is used to hold the T-shaped frames 17, providing support for the block 23 to slide into the interior of the mounting block 3. The movement of the fixed base 21 is restricted by the limiting rod 22.

[0032] Working principle: When using this structure, the workpiece to be processed is placed on the upper surface of the lower mold base 2. The motor 5 drives the transmission shaft 6, which in turn drives the gear 7 to rotate. This causes the toothed plates 8 on both sides to move towards the center of the transmission shaft 6, which in turn moves the L-shaped frames 9 and the positioning plates 10 on both sides towards the center of the transmission shaft 6. This causes the slide rail 11 to slide on the outer wall of the lower mold base 2, limiting the positioning plates 10. After the positioning plates 10 move, the workpiece is quickly centered and clamped. The hydraulic rod 13 drives the upper mold base 14, causing the upper mold base 14 to move downward on the outer wall of the fixed frame 12. Under the limitation of the lower die bases 2 on both sides, the plate is squeezed by the upper die base 14, thereby achieving the bending of the plate. When it is necessary to process the secondary corners of the bent plate, the upper die base 14 is pushed by the hydraulic rod 13, so that the bent plate contacts the die 4. As the upper die base 14 moves, the die 4 rotates under the limitation of the mounting block 3, further bending the secondary corners on both sides of the plate. Finally, the upper die base 14 is pulled away from the range of the lower die base 2 and the die 4 by the hydraulic rod 13. The bent plate is then manually slid out of the outer wall of the upper die base 14, thereby achieving unloading.

[0033] When maintenance of the die 4 is required, pull the slide bar 16 to move the T-shaped frame 17 to the left under the limit of the hollow block 18, compress the spring 19, and drive the connecting plate 20 to move backward through the T-shaped frame 17, so that the fixed seat 21 slides backward on the outer wall of the limit rod 22, and drives the block 23 to slide out of the interior of the worktable 1, thereby disassembling the entire mounting block 3. During use, this structure not only enables the plate to be quickly centered and positioned, improving the processing accuracy of the plate, but also enables the quick installation and disassembly of the mounting block 3 and the die 4, facilitating cleaning and maintenance.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
