Description

Technical Field

[0001] The present application relates to the technical field of pipeline processing, and in particular to a hydraulic pipe bender. Background Art

[0002] For example, the Chinese utility model patent with the announcement number CN220127291U discloses a hydraulic pipe bender for preventing pipe bending and cracking, which includes a base, a support leg, a hydraulic cylinder, a hydraulic rod, a pipe bending device and a concentric shaft. The support leg is fixedly installed at the lower end of the base, and the hydraulic cylinder is fixedly installed at the upper end of the base. The hydraulic rod is fixedly installed on the outer side of the hydraulic cylinder, and the pipe bending device is fixedly installed on the output end of the hydraulic rod. The inner side of the base is penetrated by the concentric shaft. The hydraulic pipe bender for preventing pipe bending and cracking fixes the two ends of the pipe on the inner side of the clamping block through the limit plate, and then runs the hydraulic pump to make the pipe bending device push the midpoint of the pipe to bend. When bending, the clamping block rotates through the concentric shaft, and at the same time drives the gear at the lower end to rotate. The rotation of the gear drives the outer meshing rack to slide on the inner side of the sliding track. When the rack slides to a certain position, it will be fixed on the inner side of the sliding track, so that the clamping block at the upper end is also in a fixed state. Through this structure, the bending angle is prevented from being too large.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the hydraulic pipe bender in the related technologies is not convenient to adjust according to the length of the pipe to be bent, which makes it inconvenient to perform bending operations on pipes of different lengths, thus reducing the practicality of the device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a hydraulic pipe bender. Figure 1-3 A hydraulic pipe bender comprises a workbench 1, wherein a slide groove 11 is symmetrically provided in the width direction of the top of the workbench 1, and a first bidirectional screw rod 12 is rotatably provided inside the two slide grooves 11, and both ends of the outer sides of the first bidirectional screw rod 12 are threadedly connected with a slider 4, and a fixed plate 5 is rotatably provided on the top of the slider 4, and two extrusion wheels 6 with adjustable spacing are rotatably provided on the top of the fixed plate 5, and a hydraulic cylinder 2 is fixedly installed in the middle length direction of the top of the workbench 1, and a bending head 3 is fixedly installed at the output end of the hydraulic cylinder 2.

[0021] Here, the pipe to be bent is placed between two extrusion wheels 6, and then the hydraulic cylinder 2 is started. The hydraulic cylinder 2 can push the bending head 3 to move, so that the bending head 3 can bend the pipe, and when bending, the fixed plate 5 will rotate with the bending angle of the pipe to avoid affecting the bending operation of the pipe.

[0022] Reference Figure 3 A rotating column 41 is rotatably arranged inside the slider 4 , and the fixing plate 5 is fixedly installed on the top of the rotating column 41 .

[0023] Here, a rotating column 41 is provided, and the fixing plate 5 is installed on the rotating column 41 , so that the fixing plate 5 can rotate along with the rotating column 41 .

[0024] Reference Figure 3 Two movable grooves 51 are symmetrically provided on the top of the fixed plate 5. The same second bidirectional screw rod 52 is rotatably arranged inside the two movable grooves 51. The outer ends of the second bidirectional screw rod 52 are respectively threadedly connected with movable blocks 53. The tops of the two movable blocks 53 are fixedly installed with fixed shafts 54. The two extrusion wheels 6 are respectively rotatably arranged on the outer sides of the two fixed shafts 54.

[0025] Here, by rotating the second bidirectional screw 52, ​​the second bidirectional screw 52 can push the two moving blocks 53 to move closer to or away from each other, so that the two extrusion wheels 6 can be driven to move closer to or away from each other, thereby being able to extrude pipes of different diameters, thereby improving the practicability of the device.

[0026] Reference Figure 1 A turntable is fixedly mounted at the ends of the first bidirectional screw rod 12 and the second bidirectional screw rod 52, and an anti-slip groove 11 is opened in the circumferential direction of the turntable.

[0027] Here, a turntable is provided to facilitate driving the first bidirectional screw rod 12 and the second bidirectional screw rod 52 to rotate.

[0029] Here, by providing support legs 13 and anti-slip pads 14 , the workbench 1 can be stably supported.

[0030] The implementation principle of a hydraulic pipe bender in an embodiment of the present application is as follows: when in use, the device is first placed in a designated position, and then the first bidirectional screw rod 12 is rotated. The first bidirectional screw rod 12 can push the two sliders 4 to move closer to or away from each other, so that pipes of different lengths can be bent, thereby improving the practicability of the device. Then, according to the diameter of the pipe to be bent, the second bidirectional screw rod 52 is rotated. The second bidirectional screw rod 52 can push the two moving blocks 53 to move relative to each other. The moving blocks 53 drive the fixed shaft 54 ​​and the extrusion wheel 6 to move, so that pipes of different diameters can be clamped. Then, the hydraulic cylinder 2 is started, and the hydraulic cylinder 2 pushes the bending head 3 to move, so that the pipe can be bent. When bending, the fixed plate 5 will rotate around the rotating axis following the bent pipe, thereby avoiding affecting the bending operation of the pipe.
