[0002] Manual hydraulic pipe bender is mainly used for laying and repairing pipes in power construction, road and railway construction, boilers, bridges, ships, furniture, decoration, etc. It has the advantages of multiple functions, reasonable structure, simple operation, easy movement, and quick installation. It realizes the bending of pipes by manually operating the hydraulic system. It is usually used to make various bent pipe components. Manual hydraulic pipe bender is small in size, easy to use and can be flexibly applied to construction sites. However, in actual use, when the hydraulic system pushes the pipe bending die to bend the pipe, a support point is required on both sides of the pipe to support the pipe. The support points of existing hydraulic pipe bender cannot be flexibly adjusted, resulting in limited bending angles, which cannot meet the needs of complex construction sites. Before bending, the position of the pipe needs to be maintained manually. The bending operation is inconvenient and requires multiple manual operations, which is time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-3The utility model provides a technical solution: a hydraulic pipe bending machine with a fixed structure, including a base plate 1, a bracket 2 is fixedly installed on the side of the base plate 1, a hydraulic rod 3 is installed on the bracket 2, a pipe bending mold 4 is installed on the end of the hydraulic rod 3, and support rods 16 are fixedly installed at the four corners of the bottom surface of the base plate 1. Slide grooves 5 are opened on both sides of the surface of the base plate 1, and a slider 6 is slidably connected to the inner wall of the slide groove 5. A fixed structure is installed on the upper surface of the slider 6, and a stable structure is arranged on both sides of the bottom surface of the bracket 2.

[0016] When bending the pipe, the pipe is placed on the base plate 1, the support rod 16 supports the base plate 1, the bracket 2 fixes the hydraulic rod 3, and the bending mold 4 on the hydraulic rod 3 needs to be selected in size according to actual needs. The position of the slider 6 in the slide groove 5 is adjusted, and the position of the fixed structure can be adjusted according to the length of the pipe. The stable structure sets the position of the slider 6, and the pipe is placed on the fixed structures on both sides for temporary fixation to prevent the pipe from moving when the bending mold 4 contacts the pipe.

[0017] Specifically, the fixed structure includes a first vertical rod 7, one end of which is fixedly assembled on the slider 6, and a connecting rod 8 is fixedly assembled on the side of the other end of the first vertical rod 7. A sleeve rod 10 is sleeved on the connecting rod 8, and one end of a spring 9 is fixedly assembled on the inner wall of the sleeve rod 10. The other end of the spring 9 is fixedly assembled with the connecting rod 8. Openings are provided on both sides of the sleeve rod 10, and the connecting rod 8 passes through the openings. A second vertical rod 11 is fixedly assembled on the end of the sleeve rod 10, and a sleeve 12 is rotatably sleeved on the outer walls of the first vertical rod 7 and the second vertical rod 11.

[0018] The fixing structure can temporarily fix the pipe, place the pipe between the first upright pole 7 and the second upright pole 11, and fit the pipe on the sleeve 12 on the outer wall of the first upright pole 7 and the second upright pole 11. At this time, the spring 9 undergoes elastic deformation due to its own elastic properties. The spring 9 can push the connecting rod 8 to move on the inner wall of the sleeve rod 10, so that the second upright pole 11 is close to the direction of the first upright pole 7, and the pipe is clamped and fixed. After the two ends of the pipe are fixed, the position to be bent is aligned with the pipe bending mold 4. During the bending operation, the pipe is continuously deformed. At this time, the pipe fits on the sleeve 12 and the sleeve 12 is driven to rotate as the pipe bending mold 4 moves. Under the action of the spring 9, the pipe is not only clamped to achieve the purpose of temporary fixation, but also will not affect the slight movement of the pipe during bending.

[0019] Specifically, the stabilizing structure includes a fixed seat 14, which is fixedly assembled on the bottom surface of the base plate 1, and a telescopic rod 15 is fixedly assembled on the fixed seat 14. A top block 17 is fixedly assembled on a side of the telescopic rod 15 close to the slider 6, and a protrusion 18 is fixedly assembled on the bottom surface of the slider 6. The top block 17 fits tightly with the protrusion 18 on the same side.

[0020] The stable structure can make the position of the slider 6 in the slide groove 5 more stable. After adjusting the position of the slider 6 in the slide groove 5, adjust the length of the telescopic rod 15, fit the top block 17 on the telescopic rod 15 to the position of the protrusion 18, close to the protrusion 18, and do not push the protrusion 18 to move. The telescopic rod 15 can be selected according to actual needs. Both the electric telescopic rod 15 and the pneumatic telescopic rod 15 are available. The top block 17 is located on the side of the protrusion 18. When the pipe bending mold 4 pushes the pipe to bend, the slider 6 is subjected to a certain pressure, and the protrusion 18 on the bottom surface rests on the top block 17, so as to achieve the purpose of stability, avoid the slider 6 whose position can be adjusted arbitrarily from moving when fixing the pipe, and enhance stability.

[0021] Specifically, one end of the pull rod 13 is rotatably mounted on the bottom surface of the two sliders 6 , and the other ends of the two pull rods 13 are rotatably mounted.

[0022] Two pull rods 13 are installed between the two sliders 6. When adjusting the position of the slider 6, pulling the hinged position of the two pull rods 13 can simultaneously drive the two sliders 6 to move in the two slide grooves 5 respectively, so as to facilitate simultaneous adjustment and adjust the two sliders 6 to the same position in the slide groove 5.

[0023] Specifically, the sleeve 12 is made of rubber.

[0024] The sleeve 12 is made of rubber material, which can increase the contact friction between the sleeve 12 and the pipe and improve the stability during fixation.

[0025] Working principle: When bending the pipe, place the pipe on the base plate 1, the support rod 16 supports the base plate 1, the bracket 2 fixes the hydraulic rod 3, and the bending mold 4 on the hydraulic rod 3 needs to be selected in size according to actual needs. The position of the slider 6 in the slide groove 5 can be adjusted to adjust the position of the fixed structure according to the length of the pipe. The stable structure sets the position of the slider 6, and the pipe is placed on the fixed structures on both sides for temporary fixation to prevent the pipe from moving when the bending mold 4 contacts the pipe.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
