Technical Field

[0001] This utility model relates to the field of sheet metal technology, and in particular to a tooling fixture for sheet metal forging. Background Technology

[0002] Sheet metal parts refer to products processed by sheet metal technology. They are widely used in many fields such as machinery manufacturing, automotive industry and electronics. In the sheet metal forging process, the role of tooling fixtures is crucial. They need to stably clamp the sheet metal parts to ensure that the workpiece will not be displaced or shake due to external impact during forging, thereby ensuring forging accuracy and quality.

[0003] However, most fixtures have fixed clamping dimensions and angles, making it difficult to adapt to sheet metal parts of different lengths, widths, thicknesses, and shapes. This results in the need to frequently change fixtures for different sizes of sheet metal parts, which not only increases production costs but also reduces processing efficiency. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tooling fixture for sheet metal forging. It is equipped with gears, racks, and rotating plates. Through the meshing of the gears and racks, the angle of the rotating plate can be adjusted, which can adapt to sheet metal parts of different specifications, enhance clamping adaptability, and improve the fixing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling fixture for forging sheet metal parts includes a base, a placement plate fixedly connected to the upper end of the base, two sliding grooves formed inside the base, and first threaded rods rotatably connected between the inner walls of the two sliding grooves. Slider blocks are threadedly connected to the two first threaded rods, and first electric telescopic rods are mounted on the upper ends of the two sliders. Two strip-shaped openings are formed at the upper end of the base, and the telescopic ends of the two first electric telescopic rods pass through the corresponding strip-shaped openings and are fixedly connected to lifting plates. Connecting plates are fixedly connected to the inner walls of the two lifting plates, and a fixing plate is fixedly connected to the other ends of the two connecting plates on the same side. Moving grooves are formed inside the two fixing plates, and two rotating shafts are rotatably connected to the inner walls of the two moving grooves. Gears are fixedly connected to the outer walls of each rotating shaft. Two rotating grooves are formed on the inner walls of the two fixing plates, and the upper and lower ends of each rotating shaft extend into the corresponding rotating grooves and are fixedly connected to rotating plates.

[0007] Preferably, motors are installed on both outer walls of the base, and the output shafts of the two motors extend into the corresponding slide grooves and are fixedly connected to one end of the corresponding first threaded rod.

[0008] Preferably, a second electric telescopic rod is installed on each of the two lifting plates on opposite sides, and a moving plate is fixedly connected to the telescopic end of each of the two second electric telescopic rods. The two moving plates are slidably connected to the inner wall of the corresponding moving groove, and racks are fixedly connected to the two side walls of the two moving plates. Each rack meshes with a corresponding gear.

[0009] Preferably, each of the two fixed plates is threaded with two second threaded rods, and each of the two fixed plates is slidably connected with two guide rods. One end of each pair of cooperating second threaded rods and guide rods is fixedly connected with a clamping plate.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7 A fixture for forging sheet metal parts includes a base 1, a placement plate 2 fixedly connected to the upper end of the base 1, two sliding grooves 3 formed inside the base 1, and first threaded rods 4 rotatably connected between the inner walls of the two sliding grooves 3. Slider blocks 5 are threadedly connected to the two first threaded rods 4. Motors 6, both servo motors, are installed on the outer walls of both sides of the base 1. The output shafts of the two motors 6 extend into the corresponding sliding grooves 3 and are fixedly connected to one end of the corresponding first threaded rod 4. First electric telescopic rods 7 are installed at the upper ends of the two sliders 5. Two strip-shaped openings 8 are provided at the top. The telescopic ends of the two first electric telescopic rods 7 pass through the corresponding strip-shaped openings 8 and are fixedly connected to the lifting plates 9. The two side walls of the two lifting plates 9 are fixedly connected to the connecting plates 10. Each connecting plate 10 is L-shaped. The other ends of the two connecting plates 10 on the same side are fixedly connected to the fixing plate 11. The first threaded rod 4 is driven to rotate by the motor 6, which drives the slider 5 and the connected lifting plates 9 and fixing plates 11 to move. In this way, by adjusting the distance between the two fixing plates 11, it can adapt to sheet metal parts of different length specifications.

[0025] Furthermore, through the extension and retraction of the first electric telescopic rod 7, the entire clamping assembly, including the lifting plate 9 and the fixed plate 11, can be raised and lowered vertically, thereby adjusting the height of the clamping position. Each of the two fixed plates 11 has a moving groove 12, and the inner walls of each moving groove 12 are rotatably connected to two rotating shafts 13. Each rotating shaft 13 has a gear 14 fixedly connected to its outer wall. Each of the two fixed plates 11 has two rotating grooves 15 on its side walls. The upper and lower ends of each rotating shaft 13 extend into the corresponding rotating groove 15 and are fixedly connected to a rotating plate 16. The two lifting plates 9 and 11... A second electric telescopic rod 17 is installed on each of the opposite sides of the lowering plate 9. The telescopic ends of the two second electric telescopic rods 17 are fixedly connected to a moving plate 18. The two moving plates 18 are slidably connected to the inner wall of the corresponding moving groove 12. The two side walls of the two moving plates 18 are fixedly connected to racks 19. Each rack 19 meshes with a corresponding gear 14. In this way, the moving plate 18 is pushed by the second electric telescopic rod 17, and the rotating plate 16 is rotated by the meshing transmission of the rack 19 and the gear 14, so as to clamp the sheet metal parts in multiple directions and further adapt to sheet metal parts of different shapes.

[0026] Each of the two fixed plates 11 has two threaded rods 20 threadedly connected to it, and two guide rods 21 slidably connected to each of the two fixed plates 11. A clamping plate 22 is fixedly connected to one end of each pair of mating second threaded rods 20 and guide rods 21. Each rotating plate 16 and clamping plate 22 is provided with a protective layer made of rubber. This rubber protective layer not only prevents scratches and deformation of the sheet metal parts due to rigid contact during clamping, but also increases the friction of the contact surface, improving clamping stability. Each second threaded rod 20 has a knob 23 fixedly connected to its other end, and each guide rod 21 has a limit plate 24 fixedly connected to its other end. The limit plate 24 can prevent the guide rod 21 from falling off the fixed plate 11 during sliding. Every two cooperating guide rods 21 are arranged parallel to the second threaded rods 20. When the knob 23 is turned to make the second threaded rod 20 rotate, the clamping plate 22 can only move in a straight line under the restriction of the guide rod 21, so as to avoid the clamping plate 22 from deflecting due to uneven force and ensure the accuracy of the clamping direction.

[0027] In this utility model, when in use, the sheet metal part to be processed is placed on the placement plate 2. Then, the motor 6 is started, which drives the first threaded rod 4 to rotate, thereby causing the slider 5 to move. The movement of the slider 5 will drive the lifting plate 9 and the fixed plate 11 and other overall structures to move synchronously through the first electric telescopic rod 7 and the strip-shaped opening 8. In this way, by adjusting the distance between the two fixed plates 11, sheet metal parts of different lengths can be accommodated. Furthermore, the first electric telescopic rod 7 can be started to drive the lifting plate 9 and the fixed plate 11 and other clamping components to rise and fall, thereby adjusting the height of the clamping position to meet the needs of different height clamping points during the forging process.

[0028] Then, turn the knob 23 to drive the second threaded rod 20 to rotate. Since the clamping plate 22 is restricted by the guide rod 21, the clamping plate 22 will move in a straight line towards the sheet metal part until it contacts and clamps the sheet metal part surface, thus preventing the sheet metal part from shaking or shifting during the forging process and improving the forging accuracy. In addition, the clamping plate 22 is provided with a rubber protective layer, which not only ensures the stability of the clamping but also avoids damage to the sheet metal part caused by excessive clamping.

[0029] Then, the second electric telescopic rod 17 is activated, and its telescopic end pushes the moving plate 18 to slide in the moving groove 12, thereby causing the rack 19 to move. The rack 19 meshes with the gear 14, so the movement of the rack 19 will drive the gear 14 and the connected rotating shaft 13 to rotate, thereby causing the rotating plate 16 to rotate with the rotating shaft 13 to assist in clamping the sheet metal parts. In this way, the rotating plate 16 can flexibly change its angle according to the shape of the sheet metal parts, improving the adaptability of the clamp to sheet metal parts of different specifications and shapes, and further enhancing the fixing effect of the sheet metal parts.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
