The telescopic ends of the first telescopic rods 17 are connected to the support plate 8, so as to enable the support plate 8 to be stably lifted and ensure the smooth progress of subsequent bending operations. A bending plate 9 is provided at one end of the support plate 8 close to the side plate of the support frame 1, so as to perform bending operations on the workpieces on the support plate 8;

[0042] A bending drive assembly is provided at the bottom end of the bending plate 9. The bending drive assembly includes a connecting plate 1301 and a second cylinder 1302 provided at one end of the top of the connecting plate 1301 near the side plate of the support frame 1. The connecting plate 1301 is arranged at one end of the top of the workbench 6 near the side plate of the support frame 1.

[0043] Start the second cylinder 1302 to drive the sliding bar 1306 to move to the side away from the side plate of the support frame 1, thereby driving the first rotating shaft 1308 to rotate counterclockwise and making the bending plate 9 rotate counterclockwise to the horizontal position. Then place the workpiece on the support plate 8.

[0044] Sliding grooves 10 are provided on both the front and rear sides of the top plate of the support frame 1. A number of first sliding columns 11 are slidably connected in the sliding grooves 10. A pressing plate 12 is arranged at the bottom of the first sliding column 11.

The first rack 1402 and the second rack 1404 are connected with the pressing plate 12 through the first sliding column 11. Thus, the pressing plates 12 on the left and right sides can be driven to move towards each other, and their movement can meet the pressing operations of different workpieces.

[0045] A control panel 19 is arranged at the upper left part of the support frame 1. Thus, through the operation of the control panel 9, the control of various components such as the first motor 2 and the first cylinder 7 can be realized, which is convenient for the staff to use.

[0046] After the workpiece is placed on the support plate 8, start the first motor 2 to drive the forward and reverse lead screw 2 to rotate, and then drive the moving blocks 4 to move towards each other simultaneously to a suitable position. Then place the workpiece on the workbench 6, and then start the second motor 1401 to drive the driving gear 1402 to rotate, and then drive the first rack 1403 and the second rack 1404 to move towards each other simultaneously. Then drive the pressing plates 12 on both the left and right sides to move towards each other simultaneously to a suitable position. Then start the first cylinder 7 to drive the support plate 8 to move upward, and then make the pressing plates 12 press the workpiece tightly;

[0047] After pressing the workpiece tightly, reverse the second cylinder 1302 to drive the sliding bar 1306 to move towards the side close to the side plate of the support frame 1, and then drive the first rotating shaft 1308 to rotate clockwise, so that the bending plate 9 rotates clockwise to the vertical position to perform double-sided bending on the workpiece;

[0048] As Figure 4 shown, a third cylinder 15 is arranged on the top of the top plate of the support frame 1. The piston end of the third cylinder 15 passes through the top plate of the support frame 1 and is connected with a suction component. The suction component includes a lifting plate 1601. The piston end of the third cylinder 15 passes through the top plate of the support frame 1 and is connected with a lifting plate 1601. A second telescopic rod 18 is arranged on the bottom surface of the top plate of the support frame 1. The telescopic end of the second telescopic rod 18 is connected with the lifting plate 1601, so as to ensure the stable lifting of the lifting plate 1601. A third motor 1602 is arranged at the center position on the top of the lifting plate 1601. The output shaft of the third motor 1602 passes through the lifting plate 1601 and is connected with a second rotating shaft 1603. A rotating plate 1604 is arranged at the bottom end of the second rotating shaft 1603, so as to be able to adjust the angle of the rotating plate 1604 through the third motor 1602. A plurality of suction cups 1605 are arranged at the bottom of the rotating plate 1604, so as to be able to suck the workpiece.

[0049] The working principle of the present utility model: First, start the first motor 2 to drive the forward and reverse lead screw 2 to rotate, and then drive the moving blocks 4 to move towards each other simultaneously to a suitable position. Then place the workpiece on the workbench 6, and then start the second motor 1401 to drive the driving gear 1402 to rotate, and then drive the first rack 1403 and the second rack 1404 to move towards each other simultaneously. Then drive the pressing plates 12 on both the left and right sides to move towards each other simultaneously to a suitable position. Then start the first cylinder 7 to drive the support plate 8 to move upward, and then make the pressing plates 12 press the workpiece tightly. At this time, reverse the second cylinder 1302 to drive the sliding bar 1306 to move towards the side close to the side plate of the support frame 1, and then drive the first rotating shaft 1308 to rotate clockwise, so that the bending plate 9 rotates clockwise to the vertical position to perform double-sided bending on the workpiece;

[0050] After the first bending of the workpiece is completed, the third cylinder 15 is started to drive the lifting plate 1601 to descend. After the suction cup 1605 abuts against the workpiece and presses the workpiece tightly, the third cylinder 15 is reversed to drive the lifting plate 1601 to rise. After the suction cup 1605 drives the workpiece to rise a certain distance, the third motor 1602 is started to drive the rotating plate 1604 to rotate 90°, so that the workpiece on the suction cup 1605 rotates 90° accordingly. At this time, the bending plate 9 is adjusted to the horizontal state, and the distance between the support plates 8 is adjusted. Then the third cylinder 15 is started to place the workpiece on the support plate 8 and press the pressing plate 12 onto the workpiece. The third cylinder is reversed to separate the suction cup 1605 from the workpiece. At this time, the workpiece can be bent again, and then the workpiece can be continuously bent to achieve four-sided bending of the workpiece.
