[0024] Specifically, first place the workpiece 6 on the rotating dial 7 of the equipment platform. The design of the rotating dial 7 enables the workpiece 6 to maintain a stable position during the processing, thereby improving the accuracy of the bending. Adjust the two adjusting bolts 4 to ensure that the workpiece 6 remains horizontal during the processing. Next, tighten the clamping bolt 10 and the clamping bolt 2 11 to firmly clamp the workpiece 6 on the equipment to ensure that the workpiece 6 is firmly immovable. At this time, the workpiece 6 is already in a stable state. According to the requirements of the part processing drawing, determine the angle at which the workpiece 6 needs to be bent. During the bending process, turn the rotating handle 5 so that the workpiece 6 gradually forms the desired bending angle during the rotation process. After the bending process is completed, loosen the adjusting bolt 4 and take out the workpiece 6.
[0025] Reference Figure 1 and Figure 4 A fixed box 18 is fixedly connected to the upper surface of the fixed base plate 3, the outer wall of the workpiece 6 is slidably connected to the inner wall of the fixed box 18, a worm 19 is rotatably connected inside the fixed box 18, a rotating shaft 20 is rotatably connected inside the fixed box 18, a worm wheel 21 is fixedly connected to the outer wall of the rotating shaft 20, the worm wheel 21 is meshed with the worm 19, the outer wall of the worm wheel 21 is rotatably connected to the inside of the fixed box 18, a gear 22 is fixedly connected to the outer wall of the rotating shaft 20, a rack 23 is slidably connected inside the fixed box 18, the rack 23 is meshed with the gear 22, a clamping plate 24 is fixedly connected to the outer wall of the clamping plate 24, and a rubber plate 25 is fixedly connected to the outer wall of the clamping plate 24;
[0026] Specifically, the worm 19 is first rotated to drive the worm wheel 21, and the worm wheel 21 is connected to the rotating shaft 20, so that the rotating shaft 20 can rotate with the rotation of the worm 19, realizing energy transmission, and providing power for the subsequent rotation of the gear 22. As the rotating shaft 20 rotates, the gear 22 will also rotate, and the gear 22 is meshed with the rack 23, so that the rack 23 can move synchronously, ensuring that the rotation of the gear 22 can be evenly transmitted to the rack 23, thereby achieving accurate positioning. The two ends of the rack 23 are respectively connected to the clamping Plate 24, when the rack 23 moves, the clamping plate 24 will also move accordingly. A rubber plate 25 is provided on the outer wall of the clamping plate 24, which has excellent wear resistance and anti-slip properties. During the bending process, the workpiece 6 needs to be accurately positioned and fixed. At this time, the clamping plate 24 will be close to the workpiece 6 and fixed by the friction between the rubber plate 25 and the workpiece 6. In this way, even during the bending process, the workpiece 6 can remain stable, preventing the workpiece 6 from moving due to the huge pressure during the bending process, thereby avoiding processing errors caused by vibration or movement.
[0027] Working principle: When manual bending equipment is needed, the workpiece 6 is placed on the rotating dial 7 of the equipment platform, the two adjusting bolts 4 are adjusted to clamp the workpiece 6 and ensure that the workpiece 6 is level, the clamping bolt 10 and the clamping bolt 2 11 are tightened, and the bending angle is adjusted as required. The rotating handle 5 is turned to complete the bending angle of the workpiece 6. First, the worm 19 is rotated to drive the worm wheel 21 and the rotating shaft 20 to rotate, and then the rotation of the rotating shaft 20 drives the gear 22 to rotate, thereby driving the racks 23 on both sides to move synchronously, and then the rack 23 drives the splint 24 to move, and finally the rubber plate 25 on the outer wall of the splint 24 fits with the workpiece 6, so that the workpiece 6 can be positioned and fixed during the bending process.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
