Description

Technical Field

[0001] This utility model relates to the field of hinge bending machines, and more specifically, to an angle adjustment device for a hinge bending machine. Background Technology

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. Hinges can be made of movable components or foldable materials. During the production of hinges, bending processing is required. A special bending machine for hinges is mainly a machine used to bend hinges as needed during production, processing and use.

[0003] Because existing hinge bending machines cannot adjust the bending radius of the workpiece, they cannot meet the processing requirements of the workpiece, resulting in reduced processing efficiency. Furthermore, they cannot cool down workpieces with high temperatures, thus affecting the service life of the hinge after processing. Therefore, people have improved the machine by setting bending angle adjustment components and heat dissipation components to meet various processing requirements of the workpiece. For example, Chinese utility model patent with announcement number CN222113133U discloses a new type of hinge bending machine.

[0004] However, during the use of the aforementioned bending machine, it is found that because the hinge is tightly fitted to the bending plate on the fixed frame, when the heat dissipation component dissipates heat from the hinge, the cold air cannot directly contact the hinge, which reduces the heat dissipation efficiency of the heat dissipation component on the hinge. How to invent a hinge bending machine to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an angle adjustment device for a hinge bending machine, which aims to solve the problem that cold air cannot directly contact the hinge.

[0006] This utility model is implemented as follows:

[0007] This utility model provides an angle adjustment device for a hinge bending machine, including a base and a bracket. A dual-axis motor is mounted on the base, and lead screws are fixedly connected to the output shafts on both sides of the dual-axis motor. A movable frame is connected to the lead screw, and a hinge body is arranged between the movable frames. The bracket is connected to one side of the base, and a cylinder is mounted on one end of the bracket. A toothed plate is fixedly connected to the output end of the cylinder. Gears are arranged on both sides of the toothed plate, and the gears mesh with the toothed plate. An adjusting rod is fixedly connected to the gear, and an extension rod is slidably connected to the side of the adjusting rod away from the gear. An elastic component is fixedly connected to the extension rod, and a buckle is fixedly connected to the end of the elastic component away from the extension rod. The buckle engages with the hinge body.

[0008] Preferably, the base has a sliding groove, and the lead screw and the movable frame are both disposed inside the sliding groove, with the side of the movable frame fitting against the inner wall of the sliding groove; this facilitates the movement of the movable frame in conjunction with the lead screw.

[0009] Preferably, a screw is laterally connected to the end of the movable frame away from the lead screw, and a limiting groove is provided at both ends of the hinge body, with one end of the screw inserted into the limiting groove; this facilitates fixing according to hinge bodies of different lengths.

[0010] Preferably, a protective cover is fixedly connected to the bracket, and the toothed plate and the gear are both disposed inside the protective cover, with the toothed plate longitudinally disposed between the gears; this helps to extend the service life of the gear and the toothed plate.

[0011] Preferably, a locking element is provided laterally on the adjusting rod, the locking element being composed of bolts, and multiple through holes are provided in a rectangular array on the extension rod, with the locking element passing laterally through the through holes; this facilitates adjustment according to the width of the hinge body.

[0012] Preferably, the elastic component has a telescopic rod inside, with both ends of the telescopic rod being fixedly connected to the extension rod and the buckle, respectively; this helps to improve the stability of the elastic component.

[0013] Preferably, the buckle has a "U" shaped structure, and a rubber pad is provided inside the buckle, with the rubber pad corresponding to both sides of the hinge body; to prevent the surface of the hinge body from being scratched by the buckle.

[0014] The beneficial effects of this utility model are:

[0015] This hinge bending machine's angle adjustment device, by mounting a dual-axis motor, lead screw, moving frame, and threaded rod on the base, can fix both ends of the hinge body. The moving frame and threaded rod can be adjusted according to the length of the hinge body. Furthermore, the telescopic rod cooperates with the adjusting rod to accommodate hinge bodies of different widths. The elastic component between the latch and the extension rod, as well as the telescopic rod, can also be adjusted according to the position of the hinge body, ensuring that the latch remains engaged with the hinge body at all times. This allows the hinge body to be adjusted in angle along with the adjusting rod, offering good flexibility. This hinge bending machine expands the size range of hinge processing by bending hinges of different sizes. Its angle adjustment device, with a bracket, toothed plate, gear, and adjusting rod on one side of the base, drives the latch to bend the hinge body from both sides. This reduces the contact structure and area with the hinge body, providing space directly corresponding to the heat dissipation component. This allows the cool air from the heat dissipation component to directly contact the hinge body, preventing waste of the heat dissipation component's performance and rationally utilizing heat dissipation resources to cool the hinge body, thereby improving the heat dissipation efficiency of the machine.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example, refer to Figures 1-5 An angle adjustment device for a hinge bending machine includes a base 1 and a bracket 7;

[0025] A dual-axis motor 2 is mounted on the base 1. Both output shafts of the dual-axis motor 2 are fixedly connected to lead screws 3. A movable frame 4 is connected to the lead screw 3. A hinge body 6 is set between the movable frames 4. A bracket 7 is connected to one side of the base 1. A cylinder 8 is mounted on one end of the bracket 7. A gear plate 10 is fixedly connected to the output end of the cylinder 8. Gears 11 are set on both sides of the gear plate 10. The gears 11 mesh with the gear plate 10. An adjusting rod 12 is fixedly connected to the gear 11. An extension rod 13 is slidably connected to the side of the adjusting rod 12 away from the gear 11. An elastic component 14 is fixedly connected to the extension rod 13. A buckle 15 is fixedly connected to the end of the elastic component 14 away from the extension rod 13. The buckle 15 engages with the hinge body 6.

[0026] Furthermore, a sliding groove is provided on the base 1, and the lead screw 3 and the movable frame 4 are both set inside the sliding groove, with the side of the movable frame 4 fitting against the inner wall of the sliding groove.

[0027] It should be noted that by opening a sliding groove on the base 1, the movement trajectory of the moving frame 4 can be guided, making it easier to control the movement of the moving frame 4 in conjunction with the lead screw 3.

[0028] Furthermore, a screw 5 is laterally connected to the end of the movable frame 4 away from the lead screw 3, and limit grooves 18 are opened at both ends of the hinge body 6, with one end of the screw 5 inserted into the limit groove 18.

[0029] It should be noted that by threading the screw 5 onto the movable frame 4, the hinge body 6 can be fixed in conjunction with the limiting groove 18, which is convenient for fixing hinge bodies 6 of different lengths.

[0030] Furthermore, a protective cover 9 is fixedly connected to the bracket 7, and the toothed plate 10 and gear 11 are both located inside the protective cover 9, with the toothed plate 10 arranged longitudinally between the gears 11.

[0031] It should be noted that by providing protection for gear 11 and gear plate 10 by setting a protective cover 9 on bracket 7, the probability of gear 11 and gear plate 10 being damaged by external factors can be reduced, which helps to extend the service life of gear 11 and gear plate 10.

[0032] Furthermore, a locking element 16 is provided laterally on the adjusting rod 12. The locking element 16 is composed of bolts. Multiple through holes 17 are provided in a rectangular array on the extension rod 13. The locking element 16 passes through the through holes 17 laterally.

[0033] It should be noted that by setting locking parts 16 and several through holes 17 on the adjusting rod 12 and the extension rod 13 respectively, the position of the extension rod 13 on the adjusting rod 12 can be adjusted according to people's needs, which helps people to adjust according to the width of the hinge body 6.

[0034] Furthermore, the elastic component 14 is provided with a telescopic rod inside, and the two ends of the telescopic rod are fixedly connected to the extension rod 13 and the buckle 15, respectively.

[0035] It should be noted that by providing a telescopic rod inside the elastic component 14, the swaying of the elastic component 14 can be limited, allowing the elastic component 14 to move according to the extension and retraction direction of the telescopic rod, which helps to improve the stability of the elastic component 14.

[0036] Furthermore, the buckle 15 has a "U" shaped structure, and rubber pads are provided inside the buckle 15, with the rubber pads corresponding to both sides of the hinge body 6.

[0037] It should be noted that by setting a rubber pad inside the U-shaped buckle 15, the tightness of the fit between the buckle 15 and the hinge body 6 can be improved, preventing the surface of the hinge body 6 from being scratched by the buckle 15.

[0038] The working principle of the angle adjustment device of this hinge bending machine is as follows: During use, the hinge body 6 is placed on the base 1, and the dual-axis motor 2 is started to drive the lead screw 3 to rotate, thereby controlling the moving frames 4 to move closer or further apart on the base 1 until the moving frames 4 are respectively in contact with both sides of the hinge body 6. Then, the screw 5 is rotated, causing it to move into the limiting groove 18 to limit the hinge body 6. Then, the position of the extension rod 13 at the end of the adjusting rod 12 is moved so that the distance between the extension rods 13 is in contact with the width of the hinge body 6, and then the locking member 16 passes through... The through hole 17 limits the extension rod 13. Finally, the buckle 15 is pulled to extend the elastic component 14 and engage the buckle 15 with the side of the hinge body 6, thus completing the fixation of the hinge body 6. After the hinge body 6 is fixed, the cylinder 8 installed on the top surface of the bracket 7 is activated, causing the cylinder 8 to drive the toothed plate 10 to descend inside the protective cover 9. At this time, the gears 11 on both sides will drive the adjusting rod 12 to rotate together, thereby causing the extension rod 13 to drive the buckle 15 and the hinge body 6 to rotate. After the hinge body 6 is bent to a suitable position, heat dissipation can begin.

[0039] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
