[0025] The utility model embodiment discloses a multi-angle bending device for steel pipe processing.

[0026] According to the attached Figure 1-4 As shown, a multi-angle bending device for steel pipe processing includes a hydraulic cylinder 2, the other end of the hydraulic cylinder 2 is fixedly connected to a support 3, the two ends of the support 3 are fixedly connected to a limiting mold 5, and a limiting mechanism is arranged outside the support 3, and the limiting mechanism includes:

[0027] A connecting rod 72, which is fixedly mounted on the upper and lower sides of the support 3;

[0028] A base 73, which is fixedly mounted on the end of the connecting rod 72;

[0029] The screw rod 7 is disposed inside the connecting rod 72, and the screw rod 7 passes through the base 73 and the hole in the middle of the base 73;

[0030] A stopper 71 is movably sleeved on the end of the screw rod 7;

[0031] First, insert the steel pipe to be bent into the support, and insert the two ends of the steel pipe into the grooves of the limiting mold 5 respectively, and insert the bending mold 4 suitable for the size of the steel pipe. One side of the middle of the steel pipe faces the bending mold 4, and the other side faces the outside of the stopper 71. Then, the circular plate 75 is driven to rotate by rotating the lever 76, and the circular plate 75 drives the screw 7 to move back and forth along the inner wall thread of the nut sleeve 74. Then, observe the telescopic length of the screw 7 through the opening on the dial 9. When the set length is reached, stop rotating the lever 76, and put the stopper 71 on the end of the screw 7. Finally, pressurize the hydraulic cylinder 2 through the switch 8 to drive the bending mold 4 to move forward, thereby squeezing the steel pipe. When the outer wall of the steel pipe contacts the stopper 71, stop pressurizing to achieve the purpose of precise angle bending.

[0032] As a technical optimization solution of the utility model: a bending die 4 is movably inserted at the end of the hydraulic cylinder 2, and a bending die 4 suitable for the size of the steel pipe is inserted.

[0033] As a technical optimization solution of the utility model: a nut sleeve 74 is fixedly connected to the outer side of the base 73, and the screw rod 7 is threadedly connected to the inside of the nut sleeve 74, a circular plate 75 is fixedly connected to the end of the screw rod 7, and a lever 76 is fixedly connected to the edge of the circular plate 75. Then, by rotating the lever 76, the circular plate 75 is driven to rotate, and the circular plate 75 drives the screw rod 7 to move back and forth along the inner wall thread of the nut sleeve 74.

[0034] As a technical optimization solution of the utility model: a dial 9 is set in the middle of the connecting rod 72, and one end of the dial 9 is fixedly connected to the outer surface of the support 3, and the other end of the dial 9 is fixedly connected to the base 73. The telescopic length of the screw rod 7 is observed through the opening on the dial 9. When the set length is reached, the lever 76 is stopped from rotating, and a stop block 71 is put on the end of the screw rod 7.

[0035] As a technical optimization solution of the utility model: the bottom of the hydraulic cylinder 2 is fixedly connected to the cushion block 12, and the bottom of the cushion block 12 is fixedly connected to the table body 1.

Finally, the hydraulic cylinder 2 is pressurized through the switch 8 to drive the bending mold 4 to move forward, thereby squeezing the steel pipe. When the outer wall of the steel pipe contacts the stop block 71, the pressurization is stopped to achieve the purpose of precise angle bending.

[0037] This device facilitates limiting the bending angle of the steel pipe by setting the depth length of the screw rod 7. The user drives the stopper 71 to move forward and backward by rotating the lever 76 to limit the moving distance of the bending mold and thus control the bending angle of the steel pipe, thereby improving the accuracy of the device.
