Description

Technical Field

[0001] The utility model relates to the field of pipe bending equipment, in particular to a push-type pipe bending machine. Background Art

[0002] A pipe bender is a device used to process metal pipes. Its main function is to bend metal pipes into the desired shape according to a specific angle or curve. Pipe bender is used more and more widely, mainly in the laying and repair of pipelines in power construction, road and railway construction, boilers, bridges, ships, furniture, decoration, etc. The existing pipe bending machinery has the advantages of simple operation and fast bending speed. The pipe bender can process various types of pipes, including steel pipes, aluminum pipes, copper pipes and other metal pipes to meet the pipe processing of different specifications and requirements.

[0003] After searching, the announcement number: CN204159697U discloses a push-type pipe bending machine with controllable bending radius, including a fixed seat, a bending radius control device and a heating coil. The bending radius control device includes a rotating arm, a fixed guide rail, a first clamp for clamping a pipe blank and a second clamp for clamping the rotating arm. The guide rail is provided with a slider slidably connected thereto and a limit device for limiting the position of the slider on the guide rail. The second clamp is hinged on the slider. The first clamp is fixedly arranged at one end of the rotating arm and can rotate with the rotating arm to bend the pipe blank. A roller is provided at the bottom of the first clamp, and the hinge point of the second clamp and the slider is in the first clamp. The vertical distance from the center is equal to the bending radius of the part to be bent of the tube blank. In this application, although the bending radius of the tube blank can be changed by adjusting the clamping position of the rotating arm in the second clamp, the wall surface of the bending part of the tube blank is stretched evenly, avoiding the defect of uneven wall thickness of the bent tube caused by thinning of the convex edge of the bent tube wall due to tension and thickening of the concave edge of the bent tube wall due to compression, it does not take into account that the reserved length of the bent end of the pipe is different according to the use requirements of different scenarios. The existing processing method often uses a pipe bender to bend the pipe first, and then transports the bent pipe to the cutting machine for cutting through a conveying device. A variety of equipment are required for collaborative processing, which reduces the efficiency of the bending machine. Utility Model Content

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.

[0023] Reference Figure 1-2 The utility model provides an embodiment: a push-type pipe bending machine, including an operating table 1, a fixed plate 2 is fixedly connected to the upper surface of the operating table 1, a motor 3 is fixedly connected to one side of the fixed plate 2, a rotating column 4 is fixedly connected to the output end of the motor 3, a rotating handle 5 is fixedly connected to the outer wall of the rotating column 4, a supporting plate 6 is fixedly connected to one side of the rotating handle 5, a sliding assembly is arranged on one side of the supporting plate 6, the sliding assembly includes a sliding column 13 and a connecting frame 14, one end of the sliding column 13 is fixedly connected to one side of the supporting plate 6, and the outer wall of the sliding column 13 is slidably connected to the inside of the connecting frame 14.

[0024] Specifically, first, the output end of the motor 3 is used to drive the rotating column 4 to rotate. The rotating column 4 is acted upon by the force to drive the rotating handle 5 fixedly connected to the outer wall to rotate. The movement of the rotating handle 5 is further transmitted to the support plate 6 fixedly connected on one side to make it move. At the same time, the support plate 6 is affected by the force to drive the sliding column 13 fixedly connected on one side to slide in the connecting frame 14. The sliding of the sliding column 13 causes the support plate 6 to move to above the cutting groove opened on the outer wall of the block 16, thereby achieving the effect of rotation and lifting.

[0025] Reference Figure 2 A motor 2 7 is fixedly connected to one side of the support plate 6, and a bevel gear 1 8 is fixedly connected to the output end of the motor 2 7. A baffle 9 is fixedly connected to one side of the support plate 6, and a bevel gear 2 10 is rotatably connected to one side of the baffle 9. The bevel gear 1 8 is meshed with the bevel gear 2 10. A connecting column 11 is rotatably connected inside the bevel gear 2 10, and a cutting blade 12 is rotatably connected to one end of the connecting column 11.

[0026] Specifically, the output end of the motor 2 7 drives the bevel gear 1 8 to rotate, and the bevel gear 2 10 meshing therewith is driven to rotate. The bevel gear 2 10 then drives the internally rotatably connected connecting column 11 to rotate. The movement of the connecting column 11 is transmitted to the cutting blade 12 rotatably connected thereto at one end, so that the cutting blade 12 rotates to cut the pipe, thereby achieving the cutting effect.

[0027] Reference Figure 3 and Figure 4Three fixing frames 15 are arranged on the upper surface of the operating table 1, among which a clamping block 16 is fixedly connected to the top of one of the fixing frames 15, one side of the connecting frame 14 is fixedly connected to the side wall of the clamping block 16, a motor 3 17 is fixedly connected to the bottom of the operating table 1, a rotating column 2 18 is fixedly connected to the output end of the motor 3 17, a connecting block 19 is rotatably connected to the outer wall of the rotating column 2 18, a bending block 20 is fixedly connected to the top of the connecting block 19, and two rotating plates 21 symmetrical in upper and lower directions are rotatably connected to the outer wall of the rotating column 2 18, a fixing column 22 is fixedly connected between the rotating plates 21, and a clamping column 23 is fixedly connected to one end of the fixing column 22.

[0028] Specifically, the pipe to be processed is placed inside the clamping block 16 so that it passes through the gap between the clamping column 23 and the limiting column 29 and is clamped into the inside of the bending block 20. Then, the output end of the motor three 17 drives the rotating column two 18 to start rotating. The movement of the rotating column two 18 is transmitted to the connecting block 19 connected to the outer wall rotation. The connecting block 19 transmits the force to the bending block 20 fixedly connected on the top, causing it to start rotating. At the same time, the movement of the rotating column two 18 also drives the rotating plate 21 connected to the outer wall to rotate. The movement of the rotating plate 21 drives the fixed column 22 fixedly connected inside to rotate. The movement of the fixed column 22 drives the clamping column 23 fixedly connected at one end to start rotating, causing the clamping column 23 and the bending block 20 to rotate at the same time. The pipe is bent under the rotation of the bending block 20, achieving the bending effect.

[0029] Reference Figure 1 and Figure 4 Two front-to-back symmetrical fixing frames 24 are arranged on the upper surface of the operating table 1. A telescopic rod 25 is fixedly connected to the top of the fixing frame 24. A rack 26 is fixedly connected to the output end of the telescopic rod 25. A fixing frame 27 is fixedly connected to the top of one of the fixing frames 15. The outer wall of the rack 26 is slidably connected to the inside of the fixing frame 27. A toothed wheel 28 is rotatably connected to the top of the rotating plate 21. The rack 26 is meshed with the toothed wheel 28. The top of the toothed wheel 28 is rotatably connected to a limiting column 29.

[0030] Specifically, after the bending is completed, the output end of the telescopic rod 25 drives the rack 26 to start moving inside the fixed frame 27. This movement causes the toothed wheel 28 meshing therewith to rotate, and the movement of the toothed wheel 28 drives the limit column 29 connected to the top rotation to rotate. Through the movement of the limit column 29, the pipe stuck between the limit column 29 and the clamping column 23 is loosened, achieving the effect of quickly removing the material after the bending is completed.

[0031] Working principle: when using the push-type pipe bending machine, first place the pipe inside the clamping block 16 and pass it between the clamping column 23 and the limiting column 29, and clamp it into the bending block 20, then drive the rotating column 2 18 to rotate through the output end of the motor 3 17, at this time, the rotating column 2 18 is forced to drive the connecting block 19 connected to the outer wall rotation to rotate, and at the same time, the connecting block 19 drives the bending block 20 fixedly connected on the top to rotate, and when the rotating column 2 18 rotates, it will also drive the rotating plate 21 connected to the outer wall rotation to rotate, and the rotating plate 21 drives the fixed column 22 fixedly connected inside to rotate, and the rotation of the fixed column 22 drives the clamping column 23 fixedly connected at one end to rotate, at this time, the clamping column 23 and the bending block 20 rotate at the same time, so as to bend the pipe, and after the bending is completed, the output end of the telescopic rod 25 drives the rack 26 to move inside the fixed frame 27, and at this time, the rack 26 drives the toothed wheel 28 meshing with it to rotate, and then the toothed wheel 28 drives the limiting column 29 connected to the top rotation to rotate, and through the limiting The column 29 rotates to loosen the pipe stuck between the limit column 29 and the clamping column 23, so that it can be quickly taken out after the bending is completed. When the length of the pipe is too long and needs to be cut, the rotating column 4 is driven to rotate by the output end of the motor 3. At this time, the rotating column 4 is driven by the force to drive the rotating handle 5 fixedly connected to the outer wall to rotate, and the rotating handle 5 drives the support plate 6 fixedly connected on one side to move. At the same time, the support plate 6 is driven by the force to drive the sliding column 13 fixedly connected on one side to slide inside the connecting frame 14, and the sliding of the sliding column 13 drives the support plate 6 to move above the clamping block 16. The outer wall of the clamping block 16 is provided with a cutting groove. At this time, the output end of the motor 27 drives the bevel gear 18 to rotate, and the bevel gear 18 drives the bevel gear 2 10 meshing with it to rotate, and the bevel gear 2 10 drives the connecting column 11 with the internal rotation connection to rotate. At the same time, the connecting column 11 drives the cutting blade 12 rotatably connected at one end to rotate, and then the pipe is cut by the rotation of the cutting blade 12, so that the cutting can be performed while bending.
