A center pin 4 and a bending pin 3 are fixedly connected to the upper surface of the turntable 2. A mounting plate 9 is fixedly connected to one side of the base 1. A fixing frame 5 is fixedly connected to the upper surface of the mounting plate 9. First connecting plates 11 are slidably installed on both sides of the fixing frame 5. The opposite sides of the two first connecting plates 11 are fixedly connected to an arc plate 13 through two connecting rods 12. The other sides of the two first connecting plates 11 penetrate the side wall of the fixing frame 5. The fixing frame 5 is transmission-connected to the first connecting plate 11 through a driving mechanism. The model of the motor 10 is YE2-6344-37KW. When in use, metal is passed through between the two arc plates 13 to be bent. The first connecting plate 11 can drive the two arc plates 13 to approach each other through the connecting rod 12, so that the metal can be clamped and fixed. The motor 10 is started by an external power switch, and the output end of the motor 10 can drive the turntable 2 to rotate, and the turntable 2 drives the bending pin 3 to bend the metal, thereby realizing the function of bending the metal. In this process, the two arc plates 13 can be driven to move by the driving mechanism, so that the metal can be clamped and fixed, and the clamping effect is better, which can prevent the metal from loosening during bending. At the same time, the overall structure is relatively simple, and it is very convenient to use, which improves the practicability of the bending machine.

[0021] Reference Figure 1-3The driving mechanism includes a cylinder 6 and a fixed plate 7. The cylinder 6 is fixedly installed at the middle position of the upper surface of the fixed frame 5.

The second connecting seat 17 can drive the first connecting plate 11 to move horizontally through the second connecting plate 16 and the first connecting seat 15, so that the two first connecting plates 11 can be close to each other. After the output end of the cylinder 6 is contracted, the two first connecting plates 11 can be moved away from each other.

The two first connecting plates 11 can be driven to move horizontally through the driving mechanism, and the first connecting plate 11 can drive the two arc-shaped plates 13 to approach each other through the connecting rod 12, so that the metal can be clamped and fixed. The motor 10 is started by an external power switch, and the output end of the motor 10 can drive the turntable 2 to rotate, and the turntable 2 drives the bending pin 3 to bend the metal, thereby realizing the function of bending the metal. In this process, the two arc-shaped plates 13 can be driven to move through the driving mechanism, so that the metal can be clamped and fixed, and the clamping effect is better, which prevents the metal from loosening during bending. At the same time, the overall structure is relatively simple, and it is very convenient to use, which improves the practicality of the bending machine.
