Description

Technical Field

[0001] The utility model relates to the technical field of pipe benders, in particular to a pipe bender for preparing corrosion-resistant alloy steel pipes. Background Technique

[0002] The pipe bender for preparing corrosion-resistant alloy steel pipes is a mechanical device designed specifically for processing corrosion-resistant alloy steel pipes. Such pipe benders usually have high strength, high precision and good corrosion resistance to meet the processing requirements of alloy steel pipes in complex environments. The pipe bender for preparing corrosion-resistant alloy steel pipes is mainly used for bending corrosion-resistant alloy steel pipes according to predetermined angles and shapes. Such pipe benders are widely used in fields such as petroleum, chemical industry, electric power, shipbuilding, aerospace, etc. that require high-strength and highly corrosion-resistant steel pipes.

[0003] When the existing pipe benders for steel pipe processing are in use, they generally use manual or hydraulic bending. Workers need to apply force manually for the bending work. When bending the steel pipe, it is not possible to effectively save effort, and the control force for the rotation speed is relatively low, which will reduce the processing efficiency.

[0004] The existing patent (Publication No.: CN212442698U) discloses a pipe bender for steel pipe processing, which includes a machine body, a limit disk and a roller. A connecting rod is arranged at the upper end of the machine body, and a fixing groove is connected to the left end of the connecting rod. A limit disk is installed at the right end of the connecting rod, and a second groove is opened on the limit disk. A first groove is opened on the right side of the fixing groove, and a fixing screw is installed on the left side of the fixing groove. A motor is arranged on the lower side of the left end of the machine body. By setting the connection between the connecting rod and the limit disk as a rotating structure, the motor can be started to rotate the fixing groove, and then the steel pipe can be directly bent without the need for manual pushing and bending, increasing the work efficiency and working time.

[0005] In view of the above problems, although the solution given by the existing patent can rotate the fixing groove by starting the motor by setting the connection between the connecting rod and the limit disk as a rotating structure, and then directly bend the steel pipe, it is not convenient to fix and adjust the bending arc when bending the steel pipe, resulting in inconsistent bending arcs of the steel pipe each time, affecting the subsequent use effect of the steel pipe.

Specific Embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 4 , a pipe bender for preparing corrosion-resistant alloy steel pipes, including a bending machine housing 1, a bending wheel 2 is arranged on the outer wall of the bending machine housing 1, two adjusting mechanisms for adjusting the bending radian of the steel pipe are arranged on one side of the bending machine housing 1, and a bending mechanism for bending the steel pipe is installed at the upper end of the bending machine housing 1;

[0028] The adjusting mechanism includes adjusting wheels 3. There are two adjusting wheels 3, and both of the two adjusting wheels 3 are arranged on one side of the bending machine housing 1. Limit grooves 31 opened on the bending machine housing 1 are connected to the inner sides of the two adjusting wheels 3. One end of each of the two adjusting wheels 3 is rotatably connected to a movable block 32 through a bearing. A lead screw 33 is threadedly connected inside the movable block 32. A double-shaft motor 34 is fixed to the input end of the lead screw 33, and the double-shaft motor 34 is fixedly connected to the inner wall of the bending machine housing 1. A fixed block 35 is fixed to the upper surface of the movable block 32, and a guide rod 36 fixedly connected to the inner wall of the bending machine housing 1 penetrates through the fixed block 35.

[0029] By adopting the above technical solution, before using the pipe bender for preparing the corrosion-resistant alloy steel pipe, first install the bending machine housing 1 at a suitable position. When it is necessary to adjust the bending radian, the double-shaft motor 34 is used to drive the two lead screws 33 in different directions to rotate respectively. Under the cooperation of the fixed block 35 and the guide rod 36, the rotation of the lead screw 33 drives the threadedly connected movable block 32 to move horizontally, thereby synchronously driving the two adjusting wheels 3 to move relatively. The provided limit grooves 31 can play a guiding role to adjust the distance between the two adjusting wheels 3, so that the bending radian of the steel pipe can be adjusted. And after the adjustment is completed, the subsequent bending radian of the steel pipe can be kept consistent, thereby effectively reducing the situation where the bending radian of the steel pipe cannot be kept consistent and improving the practicability.

[0030] Specifically, as Figure 1 、 Figure 3 and Figure 4 shown, the bending mechanism includes a fixing plate 4. The fixing plate 4 is fixed to the upper end of the bending machine housing 1. A hydraulic cylinder 41 is fixed to the side wall of the fixing plate 4. A connecting block 42 is fixed to the telescopic end of the hydraulic cylinder 41. Sliders 43 slidably connected to the bending machine housing 1 are fixed to both sides of the connecting block 42. A fixed bearing 44 is embedded inside the connecting block 42. A fixed rod 45 fixed to the bending wheel 2 is fixed inside the fixed bearing 44. Two mounting plates 5 are fixed to the right side of the bending machine housing 1. A conveying motor 6 is fixed to the side wall of the mounting plate 5 through screws. A conveying wheel 7 is fixed to the power output shaft of the conveying motor 6 penetrating through the mounting plate 5.

[0031] By adopting the above technical solution, the steel pipe to be bent is placed between the two conveying wheels 7 provided on the two mounting plates 5. The conveying motor 6 drives the conveying wheels 7 to rotate, thereby conveying the steel pipe. There is no need for manual conveying, improving safety. When the steel pipe moves between the bending wheel 2 and the two adjusting wheels 3, the conveying stops. The hydraulic cylinder 41 provided on the fixing plate 4 drives the connecting block 42 to move vertically, and the provided slider 43 can ensure the stability of the connecting block 42 during movement, thereby driving the bending wheel 2 to approach the two adjusting wheels 3, squeezing and bending the steel pipe, achieving the effect of automatic bending. And through the provided fixed bearing 44, the bending wheel 2 can rotate with the cooperation of the fixed rod 45, facilitating the operation.

[0032] Working principle: The steel pipe to be bent is placed between the two conveying wheels 7 provided on the two mounting plates 5. The conveying motor 6 drives the conveying wheels 7 to rotate, thereby conveying the steel pipe. When the steel pipe moves between the bending wheel 2 and the two adjusting wheels 3, the conveying stops. The hydraulic cylinder 41 provided on the fixing plate 4 drives the connecting block 42 to move vertically. The provided slider 43 can ensure the stability of the connecting block 42 during movement, thereby driving the bending wheel 2 to approach the two adjusting wheels 3, squeezing and bending the steel pipe. The double-shaft motor 34 drives the two lead screws 33 with different leads to rotate respectively. With the cooperation of the fixed block 35 and the guide rod 36, the rotation of the lead screw 33 drives the movable block 32 connected by threads to move horizontally, thereby synchronously driving the two adjusting wheels 3 to move relative to each other. The provided limit groove 31 can play a guiding role to adjust the distance between the two adjusting wheels 3, so that the bending radian of the steel pipe can be adjusted, and after the adjustment is completed, the bending radian of the subsequent steel pipes can be kept consistent.
