[0002] In the process of tractor production, bent steel plates are needed, and in the process of bending the steel plates, a bending structure is needed to ensure the bending effect of the steel plates.

[0003] However, the existing bending structure still has certain defects in use. When the steel plate is bent on the bending machine, plate debris will be generated. The steel plate bending machine proposed in the above patent does not have the ability to clean the debris. Therefore, the debris will be squeezed on the surface of the steel plate, thereby affecting the quality of the product and reducing the yield rate of the product. At the same time, the plate debris covers the workbench, which is not convenient for unified treatment.

[0004] Patent application publication number CN221046999U discloses a steel plate bending structure, in which the material is squeezed and bent into the desired state by sliding the bending assembly downward. During the bending process, material debris is generated. The bending assembly drives the compression assembly to operate during the downward sliding process. The compression assembly compresses the inhaled gas and discharges it into the air intake pipe, and finally blows it out from the blowing assembly. The above-mentioned arrangement can blow and clean the debris generated by the material during the bending process, reduce the situation where the material debris is squeezed on the material surface, and improve the quality of the product. At the same time, the debris cleaning process does not require manual operation by personnel, saving manpower and reducing the risk of personal injury.

During the use of the bending structure, the steel plate needs to be placed on the upper end of the workbench. At this time, the electric telescopic column can push the pressure plate downward and squeeze and bend the steel plate. The steel plate needs to be placed on the upper end of the workbench manually. The manual operation is easily affected by external factors, and it is easy to cause the steel plate to shift during the placement process, affecting the accuracy of the bending effect of the steel plate.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original bending structure. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] In a specific embodiment, Figure 1 As shown, the basic use process of the simple hand-cranked steel plate bending structure is disclosed;

[0032] A support base 1 and a fixing bolt 2 threadedly mounted inside the support base 1;

[0033] A roller 3 is rotatably mounted on the outer side of the fixing bolt 2, a fixing cylinder 4 is fixedly mounted on the upper end of the support base 1, and a rotating base 5 is slidably mounted inside the upper end of the fixing cylinder 4, a hand crank operating lever 6 is rotatably mounted inside the rotating base 5, and a squeezing roller 7 is fixedly mounted on the end of the hand crank operating lever 6 close to the roller 3;

[0034] During the production of tractors, the steel plates need to be bent, and in order to facilitate the bending of the steel plates at any time, the steel plate bending structure needs to be used;

[0035] When using this simple hand-cranked steel plate bending structure, the steel plate to be bent needs to be placed on the upper end of the two sets of rollers 3. At this time, the squeezing roller 7 can move downward and contact the middle of the steel plate, so that the steel plate is squeezed by the squeezing roller 7 and deformed. By controlling the moving distance of the squeezing roller 7, the bending angle of the steel plate can be controlled. At this point, the use process of the structure is completed, which effectively improves the practicality of the structure.

[0036] In one specific embodiment, Figures 1-4 As shown, the process of adjusting the bending angle of the steel plate inside the structure is disclosed;

[0037] The upper end of the support base 1 is provided with an adjustment structure, and the adjustment structure can control the moving distance of the squeezing roller 7;

[0038] The adjustment structure includes a positioning bolt 9 and an adjustment seat 10. The positioning bolt 9 is threadedly installed inside the support seat 1, and the adjustment seat 10 is rotatably installed on the outside of the positioning bolt 9. The adjustment seat 10 is tilted inside the support seat 1 and is located at the upper end of the rotating seat 5.

[0039] The adjustment structure also includes a screw 11 and an adjusting nut 12. The screw 11 is rotatably mounted inside the support base 1, and the adjusting nut 12 is threadedly mounted on the outer side of the screw 11. The screw 11 is slidably connected to the adjusting base 10, and the adjusting base 10 is located at the lower end of the adjusting nut 12. A return spring 13 is sleeved on the outer side of the screw 11, and the return spring 13 is located at the lower end of the adjusting base 10.

[0040] A support spring 8 is fixedly installed inside the fixed cylinder 4 , and the upper end of the support spring 8 is fixedly connected to the rotating seat 5 .

[0041] During the downward movement of the squeezing roller 7, the adjusting nut 12 needs to be rotated by a wrench. The rotation of the adjusting nut 12 will push the adjusting seat 10 to move downward on the outside of the screw 11. In the process of the downward movement of the adjusting seat 10, the return spring 13 will be squeezed and the return spring 13 will be contracted. During this process, the adjusting seat 10 will rotate on the outside of the positioning bolt 9, and the lower end of the screw 11 will rotate at the same time.

[0042] When the adjusting seat 10 rotates, it will contact the upper end of the rotating seat 5 and push the rotating seat 5 to move downward. The downward movement of the rotating seat 5 will drive the squeezing roller 7 to move downward synchronously and cause the supporting spring 8 to contract. The downward movement of the squeezing roller 7 will contact the steel plate and squeeze the steel plate. At this time, the steel plate will bend and deform. By controlling the position of the screw 11, the movement distance of the squeezing roller 7 can be controlled, and the bending angle of the steel plate can be controlled.

[0043] Based on the above embodiments, Figures 1-6 As shown, the automatic limiting process of the steel plate by the structure is disclosed;

[0044] A limiting structure is provided inside the support seat 1, and the limiting structure can automatically limit the steel plate;

[0045] The limiting structure includes a sliding groove 14, and the sliding groove 14 is opened at the upper end of the support base 1, and a sliding rod 16 is slidably installed inside the sliding groove 14, and a docking rod 20 is fixedly installed at the lower end of the sliding rod 16;

[0046] Two groups of sliding grooves 14 and sliding rods 16 are symmetrically arranged about the vertical center axis of the support base 1, and a traction rope 19 is fixedly installed at one end of the sliding rod 16 close to the middle position of the support base 1;

[0047] The limiting structure also includes a positioning groove 21, and the positioning groove 21 is opened on the outer sides of the left and right ends of the support base 1, and the weight block 18 is slidably installed inside the positioning groove 21, and the upper end of the weight block 18 is fixedly installed with a traction rope 17, and the end of the traction rope 17 away from the weight block 18 is fixedly connected to the sliding rod 16;

[0048] A clamping member 15 is mounted inside the support base 1 , and the clamping member 15 is fixedly connected to an end of the second traction rope 19 away from the sliding rod 16 .

[0049] During the bending process of the bending structure for bending the steel plate, the steel plate needs to be placed on the upper ends of the two groups of rollers 3 first, and then the engaging member 15 can be separated from the support seat 1 and automatically move downward. The mass of the engaging member 15 is greater than the mass of the two groups of weighting blocks 18. During the downward movement of the engaging member 15, the two groups of sliding rods 16 will be pulled by the traction rope 2 19 to move, and the sliding rods 16 will move closer to each other and drive the docking rods 20 to move. During the movement of the docking rods 20, they will contact the two ends of the steel plate. At this time, the steel plate will roll on the upper ends of the rollers 3, so that the steel plate is centered on the upper ends of the two groups of rollers 3, ensuring the accuracy of the bending of the steel plate, while improving the convenience of using the structure and increasing the overall practicality.
