Technical Field

[0001] The utility model relates to the technical field of pipe cutting equipment, in particular to a steel pipe cutting machine for preventing deformation. Background Technique

[0002] Steel pipes are an indispensable material in industrial production. The pipe walls of steel pipes are sometimes thick and sometimes thin. When processing thin-walled steel pipes, it is necessary to cut them to a certain length so that the size of the steel pipes meets the usage requirements.

[0003] Chinese Patent No. 202220813118.6 discloses a steel pipe cutting and blanking device, including a base. A square groove penetrating left and right is opened at the upper end of the base. Four uniformly distributed fixing frames are connected to the upper end of the base. Two symmetrical sliding rods are connected between the fixing frames. Two sliders are slidably connected to the sliding rods. A C-shaped frame B is connected between the sliders. A C-shaped frame A is connected to the upper end of the C-shaped frame B. A semi-circular groove is opened in the C-shaped frame B. An arc-shaped clamping piece is arranged at the upper end of the semi-circular groove. A threaded rod is rotatably connected to the center of the upper end of the arc-shaped clamping piece. The threaded rod is rotatably connected to the C-shaped frame A. The threaded rod passes through the C-shaped frame A and is connected with a threaded sleeve A. The threaded rod passes through the threaded sleeve A and is connected with a crank. One end of the sliding rod away from the C-shaped frame A is slidably connected with a baffle frame. A threaded sleeve B is connected to the upper end of the baffle frame. The threaded sleeve B is threadedly connected with a hand-twisting bolt. When the steel pipe cutting and blanking device in the above patent cuts a thin-walled steel pipe, due to the thin wall thickness of the thin-walled steel pipe, the stress strength of its outer wall is weak, resulting in deformation easily occurring at the cutting position of the steel pipe. Therefore, it is urgent to design a steel pipe cutting machine for preventing deformation to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a steel pipe cutting machine for preventing deformation to solve the above deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A steel pipe cutting machine for preventing deformation, including a frame. One outer wall of the frame is connected with a rotating shaft through a bearing. A rotating column and a conical column are fixed to the outside of the rotating shaft. A gap is left between the rotating column and the conical column. A pipe body is sleeved outside the rotating column and the conical column. A motor is arranged at the top of the pipe body. A cutting piece is fixed to the output shaft of the motor. The gap is adapted to the cutting piece. An installation shell is fixed to one outer wall of the frame away from the pipe body. One end of the rotating shaft extends into the interior of the installation shell and is fixed with a worm gear. A worm is connected to the interior of the installation shell through a bearing. The worm meshes with the worm gear. One end of the worm extends to the outside of the installation shell and is fixed with a hand wheel.

[0007] Further, a retaining disc is fixed to the outside of the rotating shaft, and one end of the pipe body abuts against the retaining disc.

[0008] Further, a nut is fixed to the outer wall of the retaining disc, and a screw rod is connected to the inside of the nut by threads.

[0009] Further, one end of the screw rod close to the pipe fitting body is connected to an arc plate through a bearing, and a protective layer is fixed to the outer wall of the side of the arc plate close to the pipe fitting body.

[0010] Further, a fixing plate is fixed to the outer wall of the top of the motor, an electric telescopic rod is fixed to the top of the frame, the output end of the electric telescopic rod is fixed to the fixing plate, a guide post is fixed to the outer wall of the top of the fixing plate, and the guide post is slidably connected to the top of the frame.

[0011] Further, a protective cover is fixed to the outer wall of one side of the fixing plate, the cutting slice is located inside the protective cover, an arc-shaped opening adapted to the pipe fitting body is provided on the outer wall of the bottom of the protective cover, and an oil inlet nozzle is fixed to the outer wall of the top of the mounting shell.

Specific implementation manners

[0022] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0023] As Figures 1-5 shown, a steel pipe cutting machine with anti-deformation provided by an embodiment of the present utility model includes a frame 1. One outer wall of the frame 1 is connected with a rotating shaft 3 through a bearing. A rotating column 4 and a conical column 5 are fixed on the outside of the rotating shaft 3. A gap 6 is left between the rotating column 4 and the conical column 5. A pipe fitting body 22 is sleeved on the outside of the rotating column 4 and the conical column 5. A motor 8 is arranged at the top of the pipe fitting body 22. A cutting piece 9 is fixed on the output shaft of the motor 8. The gap 6 is adapted to the cutting piece 9. One outer wall of the frame 1 far away from the pipe fitting body 22 is fixed with a mounting shell 2. One end of the rotating shaft 3 extends into the inside of the mounting shell 2 and is fixed with a worm gear 13. A worm 14 is connected with the mounting shell 2 through a bearing. The worm 14 meshes with the worm gear 13. One end of the worm 14 extends to the outside of the mounting shell 2 and is fixed with a hand wheel 16.

[0024] Specifically, in this embodiment, it includes a frame 1. One outer wall of the frame 1 is connected to a rotating shaft 3 through a bearing. A rotating column 4 and a conical column 5 are fixed to the outside of the rotating shaft 3. There is a gap 6 between the rotating column 4 and the conical column 5. A pipe fitting body 22 is sleeved outside the rotating column 4 and the conical column 5. The pipe fitting body 22 is a thin-walled steel pipe to be cut. The rotating column 4 and the conical column 5 play a supporting role for the pipe fitting body 22. At the same time, one end of the conical column 5 is conical, making it convenient for the pipe fitting body 22 to be sleeved outside the rotating column 4 and the conical column 5. A motor 8 is arranged at the top of the pipe fitting body 22. A cutting piece 9 is fixed to the output shaft of the motor 8. The gap 6 is adapted to the cutting piece 9. The motor 8 is used to drive the cutting piece 9 to cut the pipe fitting body 22. At the same time, the gap 6 provides a clearance for the cutting piece 9, enabling the cutting piece 9 to cut through the outer wall of the pipe fitting body 22. On one outer wall of the frame 1 away from the pipe fitting body 22, an installation shell 2 is fixed. One end of the rotating shaft 3 extends into the interior of the installation shell 2 and is fixed with a worm gear 13. A worm 14 is connected to the interior of the installation shell 2 through a bearing. The worm 14 meshes with the worm gear 13. When the worm 14 rotates, it drives the worm gear 13 and the rotating shaft 3 to rotate. One end of the worm 14 extends outside the installation shell 2 and is fixed with a handwheel 16, which facilitates the rotation of the worm 14.

[0025] A steel pipe cutting machine for preventing deformation provided by the present utility model supports inside the pipe fitting body 22 through the provided rotating column 4 and conical column 5, and drives the pipe fitting body 22 to rotate through the rotating shaft 3, enabling the cutting tool to cut the outer wall of the pipe fitting body 22, so that the pipe fitting body 22 with a relatively thin wall will not deform during cutting, thereby improving the cutting quality of the steel pipe.

[0026] In another embodiment provided by the present utility model, as Figure 2 、 Figure 4 and Figure 5 shown, a retaining disc 23 is fixed to the outside of the rotating shaft 3. One end of the pipe fitting body 22 abuts against the retaining disc 23, using the retaining disc 23 to block one end of the pipe fitting body 22, so that the pipe fitting body 22 can be cut to a fixed length; a nut 18 is fixed to the outer wall of the retaining disc 23, and a screw rod 19 is connected to the interior of the nut 18 through a thread; one end of the screw rod 19 close to the pipe fitting body 22 is connected through a bearing with an arc plate 20, and the arc plate 20 is adapted to the pipe fitting body 22. The screw rod 19 drives the arc plate 20 to squeeze and fix the pipe fitting body 22, and the rotating column 4 supports the extrusion of the arc plate 20 to prevent the pipe fitting body 22 from being deformed by extrusion during fixation. A protective layer 21 is fixed to the outer wall of the arc plate 20 close to the pipe fitting body 22. At the same time, the protective layer 21 can prevent the outer wall of the pipe fitting body 22 from being bruised.

[0027] In another embodiment provided by the present utility model, as Figure 2As shown in the figure, a fixed plate 7 is fixed to the outer wall of the top of the motor 8, and an electric telescopic rod 11 is fixed to the top of the frame 1. The output end of the electric telescopic rod 11 is fixed to the fixed plate 7. The electric telescopic rod 11 is used to drive the fixed plate 7 and the motor 8 to move up and down, so that when the cutting slice 9 cuts the pipe body 22, the cutting tool can be advanced and retracted. A guide post 12 is fixed to the outer wall of the top of the fixed plate 7. The guide post 12 is slidably connected to the top of the frame 1. The sliding of the guide post 12 on the top of the frame 1 makes the cutting slice 9 more stable when advancing and retracting the knife.

[0028] In another embodiment provided by the present utility model, as Figure 1 , Figure 2 and Figure 3 shown, a protective cover 10 is fixed to one outer wall of the fixed plate 7. The cutting slice 9 is located inside the protective cover 10. The protective cover 10 provided can prevent the metal chips generated when cutting the pipe body 22 from splashing. An arc-shaped opening 15 adapted to the pipe body 22 is provided on the bottom outer wall of the protective cover 10. An oil inlet nozzle 17 is fixed to the top outer wall of the mounting shell 2. The oil inlet nozzle 17 can inject lubricating oil into the interior of the mounting shell 2, so that the worm 14 and the worm gear 13 can be lubricated when meshing and driving; a collection groove 24 is fixed inside the frame 1. The collection groove 24 is located at the bottom of the pipe body 22. The collection groove 24 can collect the metal chips, making it more convenient to clean the metal chips.

[0029] Working principle: When it is necessary to cut the pipe body 22, the pipe body 22 is sleeved outside the rotating column 4 and the conical column 5, and one end of the pipe body 22 is in contact with the stop plate 23. Then the screw 19 is rotated, so that the screw 19 drives the arc plate 20 to squeeze the pipe body 22, so that the pipe body 22 is fixed on the rotating column 4. At this time, the motor 8 drives the cutting slice 9 to rotate, so that the cutting slice 9 cuts the outer wall of the pipe body 22 corresponding to the gap 6. When the outer wall of the pipe body 22 is cut through, the worm 14 is rotated by the handwheel 16, so that the worm 14 drives the worm gear 13 and the rotating shaft 3 to rotate, so that the pipe body 22 rotates, so that the pipe body 22 can be cut in half by the cutting slice 9 after rotating one week, thus completing the cutting of the thin-walled steel pipe.

[0030] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
