Description

Technical Field

[0001] The utility model relates to the technical field of pipe benders, in particular to an adjustable pipe bender applicable to pipes with different pipe diameters. Background Technique

[0002] A pipe bender is a machine device used to bend metal pipes into different shapes. It is widely used in fields such as automobiles, aviation, construction, and furniture. Through the pipe bender, metal pipes can be bent into various angles, radii, arcs, and shapes, thereby meeting the requirements for bent pipes in different industries.

[0003] When using a pipe bender to bend a pipe, the pipe is placed between a fixed bending wheel and a moving bending wheel, and then the moving bending wheel is driven to move by hydraulic pressure to apply pressure to the pipe to make it bend. However, the inner diameter of the clamping groove for fixing the pipe on the fixed bending wheel and the moving bending wheel of the pipe bender is fixed, and usually only pipes with the same diameter can be bent. When it is necessary to bend pipes with different diameters, there is inconvenience. Therefore, we propose an adjustable pipe bender applicable to pipes with different pipe diameters.

[0027] A moving bending wheel 5, the moving bending wheel 5 is installed in a bracket 4 at the top of the pipe bender body 1, and a telescopic driving member 3 is installed in a driving groove 2 inside the pipe bender body 1 below the bracket 4;

[0028] A first fixed bending wheel 6, the first fixed bending wheel 6 is arranged below a pipe bender frame 7 at the top end of the pipe bender body 1;

[0029] A second fixed bending wheel 9, the second fixed bending wheel 9 is arranged below the pipe bender frame 7 on one side of the first fixed bending wheel 6;

[0030] Arc-shaped card slots 11 are all arranged on the outer surfaces of the moving bending wheel 5, the first fixed bending wheel 6, and the second fixed bending wheel 9;

[0031] The telescopic driving member 3 is a hydraulic cylinder, and the output end of the telescopic driving member 3 is fixedly connected to the bracket 4;

[0032] There are a total of five groups of arc-shaped card slots 11, and the inner diameters of the arc-shaped card slots 11 increase in sequence;

[0033] Specifically, place the pipe on the surface of the moving bending wheel 5. The pipe is located between the moving bending wheel 5, the first fixed bending wheel 6, and the second fixed bending wheel 9. Since arc-shaped card slots 11 with gradually increasing inner diameters are provided on the outer surfaces of the moving bending wheel 5, the first fixed bending wheel 6, and the second fixed bending wheel 9, according to the diameter of the pipe, it is clamped in the arc-shaped card slot 11 with the corresponding inner diameter.

[0034] Then, start the telescopic driving member 3 inside the driving slot 2 to drive the support 4 to move upward. The support 4 drives the moving bending wheel 5 to move upward. The moving bending wheel 5 pushes the pipe upward, and the first fixed bending wheel 6 and the second fixed bending wheel 9 press the two ends of the pipe. Under the thrust of the moving bending wheel 5 and the limiting action of the first fixed bending wheel 6 and the second fixed bending wheel 9, the pipe bends upward to complete the pipe bending work. The bending wheels of this pipe bender are equipped with card slots of various inner diameters. Clamping pipes of different diameters in card slots of different inner diameters can meet the pipe bending requirements of pipes with different diameters.

[0035] Equal-spacing circular holes 701 are provided on the outer walls of the pipe bending machine frame 7 at the positions of the first fixed bending wheel 6 and the second fixed bending wheel 9.

[0036] Adjusting plates 8 are welded on one side of the pipe bending machine frame 7 at the positions of the first fixed bending wheel 6 and the second fixed bending wheel 9, and equal-spacing U-shaped grooves 801 are provided at the bottoms of the adjusting plates 8. The U-shaped grooves 801 correspond to the circular holes 701 one by one.

[0037] Positioning rods 12 are rotatably installed inside the first fixed bending wheel 6 and the second fixed bending wheel 9.

[0038] Both ends of the positioning rod 12 respectively penetrate through the circular hole 701 and the U-shaped groove 801 and are sleeved with nuts 10. The nuts 10 are threadedly connected to the external thread strips 1201 on the outer wall of the positioning rod 12.

[0039] Specifically, unscrew the nut 10 from the positioning rod 12, and then the first fixed bending wheel 6 and the second fixed bending wheel 9 can be removed. Move the first fixed bending wheel 6 and the second fixed bending wheel 9 to the side away from the moving bending wheel 5. Then, snap the positioning rods 12 of the first fixed bending wheel 6 and the second fixed bending wheel 9 into the U-shaped grooves 801 and the circular holes 701, and tighten the nuts 10 at the ends of the positioning rods 12 to fix the first fixed bending wheel 6 and the second fixed bending wheel 9. At this time, the distance between the first fixed bending wheel 6 and the second fixed bending wheel 9 becomes larger. Similarly, when the first fixed bending wheel 6 and the second fixed bending wheel 9 are installed close to the moving bending wheel 5, the distance between the first fixed bending wheel 6 and the second fixed bending wheel 9 becomes smaller. By adjusting the distance between the first fixed bending wheel 6 and the second fixed bending wheel 9, the bending degree can be adjusted, so as to meet the requirements of different bending amplitudes.

[0040] When the embodiment of the present application is in use: First, place the pipe on the surface of the moving bending wheel 5. The pipe is located between the moving bending wheel 5, the first fixed bending wheel 6, and the second fixed bending wheel 9. Since arc-shaped card slots 11 with gradually increasing inner diameters are provided on the outer surfaces of the moving bending wheel 5, the first fixed bending wheel 6, and the second fixed bending wheel 9, according to the diameter of the pipe, it is clamped in the arc-shaped card slot 11 with the corresponding inner diameter. Then, start the telescopic driving member 3 inside the driving slot 2 to drive the support 4 to move upward. The support 4 drives the moving bending wheel 5 to move upward. The moving bending wheel 5 pushes the pipe upward, and the first fixed bending wheel 6 and the second fixed bending wheel 9 press the two ends of the pipe. Under the thrust of the moving bending wheel 5 and the limiting action of the first fixed bending wheel 6 and the second fixed bending wheel 9, the pipe bends upward to complete the pipe bending work. The bending wheels of this pipe bender are equipped with card slots of various inner diameters. Clamping pipes of different diameters in card slots of different inner diameters can meet the pipe bending requirements of pipes with different diameters. Moreover, by unscrewing the nut 10 from the positioning rod 12, the first fixed bending wheel 6 and the second fixed bending wheel 9 can be removed. Move the first fixed bending wheel 6 and the second fixed bending wheel 9 away from the moving bending wheel 5, then insert the positioning rod 12 of the first fixed bending wheel 6 and the second fixed bending wheel 9 into the U-shaped slot 801 and the round hole 701, and tighten the nut 10 at the end of the positioning rod 12 to fix the first fixed bending wheel 6 and the second fixed bending wheel 9. At this time, the distance between the first fixed bending wheel 6 and the second fixed bending wheel 9 becomes larger. Similarly, when the first fixed bending wheel 6 and the second fixed bending wheel 9 are installed close to the moving bending wheel 5, the distance between the first fixed bending wheel 6 and the second fixed bending wheel 9 becomes smaller. By adjusting the distance between the first fixed bending wheel 6 and the second fixed bending wheel 9, the bending degree can be adjusted, so as to meet the requirements of different bending amplitudes.
