[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 4 As shown, the feeding mechanism for the bending machine in this embodiment includes a bending machine body 1 and a placement plate 2. A guide plate 3 is installed on the upper surface of the bending machine body 1, which serves as a guide to accurately place the sheet metal into the slot in the bending machine body 1. Fixing plates 4 are installed on both sides of the lower surface of the placement plate 2. A lead screw 5 is installed between the opposite surfaces of the fixing plates 4. A threaded block 6 is threadedly connected to the surface of the lead screw 5. A moving groove 7 is provided on the upper end of the placement plate 2 above the threaded block 6. A connecting block 8 is installed on the upper end of the threaded block 6 inside the moving groove 7. A moving plate 9 is installed on the upper end of the connecting block 8. A clamping assembly is installed on the upper end of the moving plate 9. The clamping assembly is used to clamp the sheet material that needs to be bent. A motor 11 is installed on one end of the fixed plate 4. The motor 11 is connected to a forward and reverse circuit, which can rotate in both directions. The output end of the motor 11 is connected to the lead screw 5. The motor 11 drives the lead screw 5 to rotate. The lead screw 5 drives the threaded block 6 to move. The threaded block 6 drives the clamping assembly on the moving plate 9 to move through the connecting block 8. This moves the sheet material on the clamping assembly toward one side of the bending machine. The sheet material can be supported and moved without the need for multiple people to cooperate, making it convenient to use.

[0023] Specifically, a smooth rod 12 is installed between the fixing plates 4 at the front and rear of the lead screw 5. One end of each smooth rod 12 passes through a through hole and penetrates the threaded block 6. When the threaded block 6 moves, it moves along the surface of the smooth rod 12, which serves as a guide.

[0024] Furthermore, the clamping assembly includes a clamping plate 1001, a clamping plate 2 1002, a screw 1003, a handle 1004, and a mounting plate 1005. Mounting plates 1005 are installed on both the front and rear ends of the upper part of the moving plate 9. The clamping plate 1001 is installed on the upper part of the moving plate 9 on one side of the guide plate 3. The screw 1003 is installed at the front end of the mounting plate 1005 in front of the clamping plate 1001 through a screw hole. The rear end of the screw 1003 is rotatably connected to the clamping plate 2 1002. The handle 1004 is installed at the front end of the screw 1003. By rotating the handle 1004, the screw 1003 is driven to rotate, and the screw 1003 drives the clamping plate 2 1002 to move, which can fix the plate between the clamping plate 1001 and the clamping plate 2 1002, thereby fixing the plate that needs to be bent.

[0025] Furthermore, extension rods 13 are installed on both the front and rear sides of the end surface of the placement plate 2 away from the bending machine body 1 through through holes. The two extension rods 13 are jointly installed on the support plate 15. The support plate 15 is provided with placement grooves 16. The extension rods 13 can be pulled out from inside the placement plate 2. When bending long plates, the support plate 15 plays an auxiliary support role.

[0026] Furthermore, support rods 17 are mounted in a rectangular array on the lower surface of the placement plate 2. Each support rod 17 has a sleeve rod 18 fitted onto its lower surface. Each sleeve rod 18 has a fixing bracket 19 mounted on its surface. Each fixing bracket 19 has a fixing bolt 20 mounted on it through a screw hole. One end of the fixing bolt 20 extends to the surface of the support rod 17. Each sleeve rod 18 has a base plate 21 mounted on its lower end. By adjusting the length of the support rod 17 inside the sleeve rod 18 and fixing it with the fixing bolt 20, the height of the placement plate 2 can be adjusted. This allows for easy adjustment of the height of the placement plate 2 according to the height of the bending machine body 1, making it suitable for bending machines of various heights and demonstrating its versatility.

[0027] Furthermore, the bottom of the placement groove 16 and the placement plate 2 are on the same horizontal line, which makes it easy to keep the plate inside the placement groove 16 in a horizontal state and facilitates bending operations.

[0028] The usage method of this embodiment is as follows: Before use, all electrical appliances are connected to an external power source and controlled by a switch. First, adjust the length of the support rod 17 inside the sleeve rod 18 and fix it with the fixing bolt 20. This allows for adjustment of the height of the placement plate 2, facilitating adjustment of the height of the placement plate 2 according to the height of the bending machine body 1. During use, first, place several plates simultaneously on the moving plate 9 between the clamping plate 1001 and the clamping plate 2 1002. Then, turn the handle 1004 to drive the screw 1003 to rotate. The screw 1003 drives the clamping plate 2 1002 to move, allowing the plates to be moved. The material is fixed between clamping plate 1001 and clamping plate 2 1002. When the material is long, the extension rod 13 can be slid out from the inside of the placement plate 2. The support plate 15 is used to provide auxiliary support for the material. When bending the material, the motor 11 drives the lead screw 5 to rotate. The lead screw 5 drives the threaded block 6 to move. The threaded block 6 drives the clamping assembly on the moving plate 9 to move through the connecting block 8. This causes the material on the clamping assembly to move towards the bending machine. The bending machine is then operated to perform the bending operation. After use, the bent material can be removed by turning the handle 1004 in the opposite direction.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
