[0031] A driving mechanism, which is arranged below the table 2;

[0032] A clamping mechanism, which is arranged above the table 2;

[0033] Among them, the driving mechanism includes a brake motor 4, which is fixedly installed on the inner wall of the bottom groove 3. The other end of the output shaft of the brake motor 4 is fixedly sleeved with a rotating shaft 5, and the bottom end of the rotating shaft 5 is fixedly connected to a rocker arm 6. Side grooves 7 are provided on both sides of the inner wall of the table 2. There are two side grooves 7. A movable plate 8 is movably connected between the inner walls of the two side grooves 7. A square groove 9 is provided at the bottom end of the movable plate 8. The top of the rocker arm 6 is fixedly connected to a round block 10 located inside the square groove 9. The rocker arm 6 drives the round block 10 to rotate to make the movable plate 8 move left or right.

[0034] By starting the brake motor 4, the rotating shaft 5 can drive the rocker arm 6 and the round block 10 to rotate. Due to the rotation of the round block 10, the inner wall of the square groove 9 will be squeezed, so that the movable plate 8 can move to the left or right. Due to the movement of the movable plate 8, the bending length of the workpiece will increase or decrease.

[0035] Among them, there are:

[0036] The clamping mechanism is composed of a rotary rod 12, a clamping block 21, a cylinder 14, a push-pull block 15 and a crossbar 16;

[0037] A frame 11 is fixedly installed on the right side of the top of the table 2, a rotary rod 12 is hinged on the left side of the top of the frame 11, a clamping block 21 is fixedly connected to the bottom of the rotary rod 12, a through hole 13 is opened on the right side of the front of the rotary rod 12, a cylinder 14 is fixedly installed on the left side of the top of the inner wall of the frame 11 and the top of the cylinder 14 passes through the frame 11, a push-pull block 15 is fixedly connected to the top of the cylinder 14, a cross bar 16 is fixedly installed on the inner wall of the push-pull block 15 and the outer surface of the cross bar 16 is slidably connected to the inner wall of the through hole 13, and the push-pull block 15 drives the cross bar 16 to move upward, so that the rotary rod 12 drives the clamping block 21 to rotate.

[0038] By starting the air cylinder 14 , the push-pull block 15 can push the cross bar 16 to move upward, thereby enabling the rotary rod 12 to drive the clamping block 21 to move downward.

[0039] Among them, also include:

[0040] The bending mechanism is arranged above the frame 11 and consists of a hydraulic cylinder 17 and a pressure block 18;

[0041] The hydraulic cylinder 17 is fixedly mounted on the right side of the top of the frame 11 and the bottom of the hydraulic cylinder 17 passes through the frame 11 . The pressing block 18 is fixedly connected to the bottom end of the hydraulic cylinder 17 .

[0042] By activating the hydraulic cylinder 17 to move the pressing block 18 downward, the pressing block 18 can press the workpiece to bend the workpiece.

[0043] Guide rods 19 are fixedly mounted on both sides of the top of the pressing block 18 , and the top ends of the guide rods 19 pass through the frame 11 .

[0044] The design of the guide rod 19 can provide a good position limiting effect on the pressing block 18 , thereby making the pressing block 18 more stable during the workpiece bending process.

[0045] The outer surface of the clamping block 21 is fixedly sleeved with a sheath 20 , which is made of rubber.

[0046] The soft nature of rubber can provide good protection for the workpiece and prevent excessive clamping from leaving indentations on the workpiece surface.

[0047] The sheath 20 has a circular appearance and a rough outer surface.

[0049] The outer surface of the round block 10 is slidably connected to the inner wall of the square groove 9 , and both the outer surface of the round block 10 and the inner wall of the square groove 9 are smooth.

[0050] The outer surface of the round block 10 and the inner wall of the square groove 9 are both smooth, so that the round block 10 can slide more smoothly inside the square groove 9.

[0051] The working principle and use process of this utility model:

[0052] First, the staff can place the workpiece on the top of the table 2, and then start the cylinder 14. Due to the operation of the cylinder 14, the push-pull block 15 can drive the cross bar 16 to move upward. Due to the movement of the cross bar 16, the inner wall of the through hole 13 will be squeezed, so that the rotating rod 12 can drive the clamping block 21 to move downward, and then the sleeve 20 can move downward to press the workpiece and clamp the workpiece.

[0053] Later, when the staff needs to adjust the bending length according to the processing requirements, they can first start the brake motor 4. Due to the operation of the brake motor 4, the rotating shaft 5 can drive the rocker arm 6 and the round block 10 to rotate. Due to the rotation of the round block 10, the inner wall of the square groove 9 will be squeezed, so that the movable plate 8 can move to the left or right. Due to the movement of the movable plate 8, the bending length of the workpiece will be increased or decreased. After adjusting the bending length, the staff can start the hydraulic cylinder 17. Due to the operation of the hydraulic cylinder 17, the pressure block 18 can move downward to press the workpiece to bend the workpiece.
