This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0025] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a hydraulic composite pipe bending machine with clamping and adjustment function, including a pipe bending frame 1, a hydraulic cylinder 2 connected to the top of the pipe bending frame 1, the bottom of the piston rod of the hydraulic cylinder 2 penetrating through the top wall of the pipe bending frame 1 and connected to a movable push block 3, and several mounting holes 10 are provided at both ends of the pipe bending frame 1 in a stepped manner, with a pin 11 movably connected inside the mounting hole 10, and a positioning nut 12 connected to both ends of the pin 11, and a limit block 13 connected to the outer wall of the pin 11, so that after the movable push block 3 is driven to slide down by the hydraulic cylinder 2, the movable push block 3 can effectively bend the steel pipe.

[0027] It should be noted that the hydraulic cylinder 2 is connected to the hydraulic pump and control valve group in the external hydraulic system through hydraulic pipelines, which is common knowledge in this field, so it will not be described in detail here.

[0028] The inner wall of the pipe bending machine frame 1 is connected to a guide block 4. The inner wall of the movable push block 3 is provided with a through hole 5. The inner wall of the through hole 5 is movably connected to a movable rod 6. A return spring 7 is sleeved on one end of the movable rod 6 outside the guide block 4. The end of the return spring 7 away from the guide block 4 is connected to a movable block 8 connected to the movable rod 6. The end of the movable rod 6 inside the guide block 4 is connected to a clamping block 9. This facilitates the movable push block 3 to slide under the squeezing guidance of the guide block 4 when it slides down. The movable block 8 drives the clamping block 9 to slide towards each other through the movable rod 6 to clamp and position the steel pipe, thereby improving the stability of the pipe bending process and preventing the steel pipe from sliding and falling off.

[0029] In this embodiment, the movable rod 6 is connected to the guide block 4 through the through hole 5, and the movable rod 6 forms a telescopic structure with the guide block 4 through the return spring 7, thereby ensuring the effective sliding of the movable rod 6. The return spring 7 can drive the movable rod 6 to return to its original position and slide, thus facilitating the release of the clamping work on the steel pipe.

[0030] Regarding how the movable block 8 is squeezed to slide, this embodiment further explains that the top of the guide block 4 is provided with an inclined slope, and there are two guide blocks 4 symmetrically distributed on the inner wall of the pipe bending machine frame 1. Specifically, the movable block 8 is inclined in the side view, and the inclined shape of the movable block 8 is matched with the inclined slope of the guide block 4, thereby ensuring that when the movable block 8 slides downward, it slides laterally under the guidance of the guide block 4.

[0031] Furthermore, the inner wall of the clamping block 9 is arc-shaped when viewed from the side, and there are two clamping blocks 9 symmetrically distributed inside the guide block 4. This facilitates the effective clamping and positioning of the steel pipe after the clamping blocks 9 slide towards each other. By clamping the steel pipe, the steel pipe will not easily slide, thus avoiding the situation of the steel pipe falling off and separating.

[0032] Furthermore, the guide block 4 is arranged in a "U" shape when viewed from the side, which further facilitates the limiting of the steel pipe and prevents the steel pipe from falling off and separating.

[0033] In use, hydraulic cylinder 2 is first connected to an external hydraulic system, so that the hydraulic pump drives hydraulic cylinder 2 to start through the pipeline. After the piston rod of hydraulic cylinder 2 slides, it drives the movable push block 3 to descend. The movable push block 3 drives the movable block 8 to descend through the movable rod 6. When the movable block 8 descends, it slides laterally under the guidance of the guide block 4. Thus, the movable block 8 drives the two blocks to slide towards each other through the movable rod 6, so that the clamping block 9 can effectively clamp and position the steel pipe, thereby improving the stability of the steel pipe bending process and effectively preventing the pipe from falling off due to sliding during bending. At the same time, when the movable block 8 slides, it will drive the return spring 7 to compress and deform. When the piston rod of hydraulic cylinder 2 drives the movable push block 3 to slide upward, the elasticity of the return spring 7 will cause the movable block 8 to drive the clamping block 9 to slide in the opposite direction through the movable rod 6, so that the clamping block 9 releases its clamping work on the steel pipe. Thus, through automatic clamping and releasing, the convenience of operation is effectively improved, and the problem of cumbersome operation caused by manual clamping is solved.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
