The moving plate is located on one side of the top of the processing table, and slots are provided on the processing tables at both ends of the moving plate. Corresponding to the slots, screw grooves are provided within the processing table, and screws are installed in the screw grooves. Threaded blocks are threaded onto the screws, and the tops of the threaded blocks are connected to the bottom of the moving plate through slots.

The middle of the bottom of the arc-shaped block... The curved block has evenly spaced tooth marks. A gear groove is located in the middle of the bottom processing table of the curved block, and a gear shaft is located in the middle of the gear groove. Gears are located on the gear shaft at positions corresponding to the tooth marks. All gears mesh with the tooth marks on the bottom of the curved block through the gear groove and the curved groove, causing the threaded block to move the top moving plate together towards the workpiece. After moving to the appropriate position, the hydraulic cylinder can be activated to drive the bending plate to extend and bend the workpiece. The bending depth can be adjusted. In use, the curved block can rotate the top fixed workpiece, which can adjust the bending angle of the workpiece and can be used in conjunction with the depth adjustment.

[0005] As a further technical solution of this utility model, a bending plate is provided at the top of the inner side of the movable plate, and hydraulic cylinders are provided at both ends of the outer surface of the movable plate corresponding to the bending plate.

[0015] Please see Figure 1- / 5, An embodiment of this utility model: A sheet metal bending machine with adjustable bending depth, comprising a processing table 1 and a moving plate 2, characterized in that: a moving plate 2 is provided on one side of the top of the processing table 1, a bending plate 4 is provided at the top of the inner side of the moving plate 2, and hydraulic cylinders 3 are provided at both ends of the outer surface of the moving plate 2 corresponding to the bending plate 4, and the output end of the hydraulic cylinder 3 extends to the inner side of the moving plate 2 and connects with the bending plate 4, and slots 16 are provided on the processing table 1 at the bottom of both ends of the moving plate 2, and screw grooves 18 are provided at the positions corresponding to the slots 16 in the processing table 1, and screws 1 are provided in the screw grooves 18. 9. Each lead screw 19 is connected to a threaded block 20 by a thread, and the top of each threaded block 20 is connected to the bottom of the moving plate 2 by a slot 16. A motor 11 is provided on the side of the processing table 1 away from the moving plate 2, corresponding to one end of the lead screw 19. The output end of the motor 11 extends into the lead screw groove 18 through a bearing and a coupling and is connected to the lead screw 19. The end of the lead screw 19 away from the motor 11 extends to the outside of the processing table 1 through a bearing. The lead screw 19 section on the outside of the processing table 1 is set as a smooth shaft section. Each smooth shaft section of the lead screw 19 is provided with a synchronous pulley 12, and the synchronous pulleys 12 are connected to each other by a synchronous belt. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the motor 11 can be started to drive the lead screw 19 connected to its output shaft to rotate, which can drive the synchronous pulley 12 at the other end to rotate. The synchronous pulley 12 can drive the synchronous pulley 12 on the other side of the lead screw 19 to rotate through the synchronous belt. The synchronous pulley 12 can drive the lead screws 19 on both sides to rotate synchronously, which can drive the threaded block 20 to move. The threaded block 20 can drive the top moving plate 2 to move together, which can move the moving plate 2 towards the sheet metal workpiece. When it moves to the appropriate position, the hydraulic cylinder 3 can be started to drive the bending plate 4 to extend, which can be used to bend the sheet metal workpiece. The bending depth can be adjusted to adapt to the processing of sheet metal workpieces of different thicknesses. The inner side of the screw 19 is provided with an arc-shaped block 5 at the middle position of the top of the machining table 1, and the machining table 1 corresponding to the arc-shaped block 5 is provided with an arc-shaped groove. The middle position of the bottom of the arc-shaped block 5 is evenly provided with tooth marks. The middle position of the bottom of the machining table 1 is provided with a gear groove 9, and the middle position of the gear groove 9 is provided with a gear shaft 21. The gear shaft 21 is provided with gears 10 at the positions corresponding to the tooth marks. The gears 10 mesh with the tooth marks at the bottom of the arc-shaped block 5 through the gear groove 9 and the arc-shaped groove. The machining table 1 is provided with a motor 2 17 at one end corresponding to the position of the gear shaft 21. The output end of the motor 2 17 extends into the gear groove 9 and is connected to the gear shaft 21 through a bearing and a coupling. Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, the startable motor 17 drives the gear shaft 21 connected to its output shaft to rotate, which in turn drives the gear 10 to rotate. The gear 10 then drives the arc block 5 that meshes with it to rotate, which in turn drives the plate workpiece fixed at the top to rotate. The bending angle of the plate workpiece can be adjusted, and the depth can be adjusted as well. One end of the top of the arc-shaped block 5 is provided with a support plate 6, and a suction cup 14 is provided in the middle of the inner side of the support plate 6. An adsorption tube 13 is provided in the middle of one side of the suction cup 14, and the other end of the adsorption tube 13 extends to the outside of the support plate 6. Specifically, such as Figure 1 and Figure 2 As shown, the sheet metal workpiece is placed inside the support plate 6, and then the external vacuum pump is started, which drives the adsorption tube 13 and the suction cup 14 to perform adsorption operation, which can adsorb and fix the sheet metal workpiece. The other end of the top of the arc-shaped block 5 is provided with a support plate 2 8, and the middle position of the outer side of the support plate 2 8 is provided with a telescopic rod 7, and the output end of the telescopic rod 7 extends to the inner side of the support plate 2 8 to provide a clamping plate 15. Specifically, such as Figure 1 and Figure 2 As shown, after the workpiece is properly adsorbed, the telescopic rod 7 can be activated to extend the clamping plate 15, which can clamp and fix it, making it more secure. Both sides of the bottom tooth mark of the arc block 5 are provided with arc slide bars 22, and the processing table 1 corresponding to the arc slide bar 22 is provided with arc slide grooves 23, and the arc slide grooves 23 are slidably connected to the corresponding arc slide bars 22. Specifically, such as Figure 1 and Figure 5 As shown, when the arc block 5 rotates, it can drive the arc slide bar 22 to rotate together, allowing the arc slide bar 22 to move within the arc groove 23, thus making the rotation of the arc block 5 more stable.

[0016] Working Principle: During use, the sheet metal workpiece can be placed inside the support plate 6. Then, the external vacuum pump is activated, causing the suction tube 13 and suction cup 14 to perform suction, thus adsorbing and fixing the workpiece. Next, the telescopic rod 7 is activated, causing the clamping plate 15 to extend and clamp the workpiece securely. After the workpiece is fixed, the motor 17 is activated, driving the gear shaft 21 connected to its output shaft to rotate. The gear shaft 21 drives the gear 10 to rotate, which in turn drives the meshing arc-shaped block 5 to rotate. This allows the arc-shaped block 5 to rotate the top-fixed sheet metal workpiece, adjusting the bending angle and depth. As the arc-shaped block 5 rotates, it also drives the arc-shaped slide bar 22 to move along the arc. Moving within the slide groove 23 makes the rotation of the arc block 5 more stable. Then, the motor 11 can be started to drive the lead screw 19 connected to its output shaft to rotate. The lead screw 19 drives the synchronous pulley 12 at the other end to rotate. The synchronous pulley 12 drives the synchronous pulley 12 on the other side of the lead screw 19 to rotate through the synchronous belt. The synchronous pulley 12 drives the lead screws 19 on both sides to rotate synchronously. The lead screw 19 drives the threaded block 20 to move. The threaded block 20 drives the top moving plate 2 to move together. The moving plate 2 moves towards the sheet metal workpiece. When it moves to the appropriate position, the hydraulic cylinder 3 can be started to drive the bending plate 4 to extend, so as to perform bending operation on the sheet metal workpiece. The bending depth can be adjusted to adapt to the processing of sheet metal workpieces of different thicknesses.
