[0026] The bending machine 1 is composed of two first hydraulic rods 4, a fixed frame 5, two bending frames 7, four second hydraulic rods 8 and two hydraulic pumps 9. The first hydraulic rods 4 are controlled by the control console 3 to extend or retract. When the bending operation of the plate 2 is performed, the first hydraulic rods 4 are in the retracted state, so that the fixed frame 5 is lowered and pressed against the plate 2, and the plate 2 is fixed on the bending machine 1, so as to ensure that the plate 2 does not move during the bending process. It should be noted that when the fixed frame 5 is completely lowered to fit on the top surface of the bending machine 1, the top end edge of the fixed frame 5 fits with the bottom end edge of the through hole 6, so that the plate 2 fixed by the fixed frame 5 can be smoothly bent by the bending frame 7 which is protruded out of the through hole 6. The working power of the first hydraulic rods 4 comes from the hydraulic pump 9, which provides or returns hydraulic oil to make the piston in the first hydraulic rod 4 move, so as to realize the extension or retraction of the first hydraulic rod 4. When the bending of the plate 2 is completed, the control console 3 controls the hydraulic pump 9 to deliver hydraulic oil to the first hydraulic rod 4, so that the first hydraulic rod 4 is extended, and the fixed frame 5 is lifted, so as to facilitate the plate 2 after bending to be pushed out for subsequent polishing operation. The hydraulic pump 9 provides power source for the whole hydraulic system. It converts mechanical energy into hydraulic energy, and delivers or returns hydraulic oil to the first hydraulic rod 4 and the second hydraulic rod 8 through the pipeline. During the bending process, according to the instruction of the control console 3, the oil quantity and pressure delivered to each hydraulic rod are accurately controlled, so as to realize the extension or retraction control of the first hydraulic rod 4 and the lifting control of the second hydraulic rod 8, so as to complete the accurate bending action of the plate 2. The four second hydraulic rods 8 are installed at the bottom of the two bending frames 7, and are also powered by the hydraulic pump 9. When the plate 2 needs to be bent, the control console 3 controls the hydraulic pump 9 to deliver high-pressure oil to the second hydraulic rod 8, so that the second hydraulic rod 8 is extended, and the bending frame 7 is pushed upward. The bending frame 7 applies pressure to the plate 2 through contact with the plate 2, so that the plate 2 is bent according to the predetermined angle and shape. Since there are four second hydraulic rods 8 which are evenly distributed at both ends of the bottom of the bending frame 7, the uniform distribution of force during the bending process can be ensured, so that the bending is more accurate and stable.

[0027] The polishing machine 10 is composed of an alternating current motor 11, a fixed rod 12, a driving wheel 13, a driven wheel 14 and a polishing belt 15. The alternating current motor 11 is started under the control of the control console 3 after being connected to the power supply. It converts electrical energy into mechanical energy to generate rotary power to drive the shaft-connected driving wheel 13 to rotate. Since the driving wheel 13 and the driven wheel 14 are in a parallel state and are connected through the polishing belt 15, the rotary motion of the driving wheel 13 is transmitted to the driven wheel 14 through the polishing belt 15, so that the polishing belt 15 rotates at a high speed in a cycle. When the bent plate 2 is placed on the high-speed rotating polishing belt 15, the abrasive particles on the surface of the polishing belt 15 grind the corners of the plate 2 to remove burrs and uneven parts, achieving the polishing effect. The limiting frame 16 is integrally formed with the bending machine 1, and its position is accurately designed. When the bent plate 2 is pushed to the polishing position, the limiting frame 16 can accurately limit the position of the plate 2 to ensure that the corners of the plate 2 are in close contact with the polishing belt 15. It should be noted that the fixed rod 12 is used to fix the driven wheel 14 to prevent it from coming off during use. Specific embodiment two:

[0029] Reference Figures 1-6 A polishing and bending device for sheet metal processing, further based on the basic structure in specific embodiment one, the overall working principle is that the operator first places the plate 2 on the top surface of the bending machine 1. When placing, the plate 2 can be pushed towards the limiting frame 16, which positions the plate 2 to make the bent part of the plate 2 located at the top of the through hole 6, so that the second hydraulic rod 8 at the bottom of the through hole 6 bends the plate 2. By starting the hydraulic pump 9 through the control console 3, the first hydraulic rod 4 is retracted, driving the fixed frame 5 to descend and firmly fixing the plate 2 on the bending machine 1. Then, the control console 3 controls the hydraulic pump 9 to deliver hydraulic oil to the second hydraulic rod 8, which drives the bending frame 7 to move upwards to bend the plate 2 according to the preset shape at the through hole 6. After bending, the control console 3 controls the hydraulic pump 9 again to make the first hydraulic rod 4 extend, lifting the fixed frame 5, and the operator pushes the bent plate 2 forward to be limited by the limiting frame 16, at this time the corners of the plate 2 are just against the polishing belt 15 of the polishing machine 10. Then, the control console 3 starts the alternating current motor 11, which drives the driving wheel 13 to rotate, driving the polishing belt 15 to rotate at a high speed to polish the corners of the plate 2, thus completing the entire sheet metal processing process.

[0030] In summary:

[0031] 1. The plate 2 is fixed by the fixing frame 5 and is bent by the bending frame 7 on the bending machine 1, after the plate 2 is bent, the first hydraulic rod 4 is lifted by the control console 3, so that the fixing frame 5 is separated from the plate 2, after the separation, the bent plate 2 is pushed forward and is limited by the limiting frame 16, so that the corner of the bent plate 2 is abutted on the polishing belt 15 of the polishing machine 10, the corner of the bent plate 2 is polished by the polishing belt 15 of the polishing machine 10, and the defect that the bent plate 2 cannot be polished is solved.
