Description

Technical Field

[0001] The present application belongs to the technical field of steel pipe processing equipment, and more specifically, relates to a pipe cutting machine. Background Art

[0002] Steel pipe is a kind of steel with a hollow cross-section, which is widely used in the fields of transporting fluids, exchanging heat energy, manufacturing mechanical parts, etc. When the steel pipe is used, it needs to be cut to obtain the required length of the pipe blank.

[0003] At present, when cutting steel pipes, workers place the steel pipes on a loading platform and then push them into a pipe cutting machine to cut them into multiple shorter pipe blanks. A material box is provided under the pipe cutting machine, and the pipe blanks fall into the material box by themselves due to gravity.

[0004] The inventors found that when using an existing pipe cutting machine to cut steel pipes, the pipe blanks are likely to collide with the inner wall of the material box or other pipe blanks during their falling process, causing damage or deformation of the pipe blanks, affecting the subsequent processing of the pipe blanks; in addition, the pipe blanks that fall into the material box are scattered in the material box, making it difficult to count their number.

[0042] Please also read Figures 1 to 6 The pipe cutting machine provided by the present application is now described. The pipe cutting machine comprises a base 1, a cutting assembly 2 and a magnetic chuck 3.

[0043] The base 1 is used to be installed on a horizontal plane, and has a feeding port which runs through in the up-down direction for the tube blank 9 to pass through; a collecting box 7 is provided below the base 1, and the collecting box 7 is connected to the feeding port through a guide plate 11 which is arranged obliquely downward.

[0044] The cutting assembly 2 is arranged on the base 1 and is used to cut the steel pipe 8 along the cross-sectional direction into tube blanks 9 that can fall into and pass through the feed opening; the cutting assembly 2 can be a laser cutting machine or a saw blade cutting machine.

[0045] The magnetic suction cup 3 is arranged in the discharge port for rotation in the horizontal direction, and is connected to a driving motor 34 for transmission; the magnetic suction cup 3 has a magnetic surface for adsorbing the tube blank 9, and the driving motor 34 can drive the magnetic suction cup 3 to move to a first position with the magnetic surface facing upward and a second position with the magnetic surface facing downward.

[0046] When the magnetic chuck 3 is in the first position, power is turned on to generate magnetic force, and when the magnetic chuck 3 is in the second position, the electromagnetic force disappears.

[0047] In the embodiment of the present application, when performing the pipe cutting operation, the staff places the steel pipe 8 on the base 1, and then divides the steel pipe 8 into multiple shorter tube blanks 9 along the cross-sectional direction through the cutting assembly 2. Subsequently, the tube blank 9 falls from the discharge port on the base 1 and is sucked by the magnetic suction cup 3. The magnetic suction cup 3 rotates under the drive of the driving motor 34, and transfers the sucked tube blank 9 to the upper side of the guide plate 11. At this time, the magnetic force of the magnetic suction cup 3 disappears and the tube blank 9 is released. Finally, the tube blank 9 falls into the collecting box 7 along the inclined guide plate 11.

[0048] Compared with the prior art, the pipe cutting machine provided in the embodiment of the present application can use magnetic force to cut the tube blanks 9 one by one, thereby avoiding collision between the tube blanks 9 and the inner wall of the material box or other tube blanks 9, and improving the production quality of the tube blanks 9.

[0049] In some embodiments, please refer to Figures 1 to 4 As a specific embodiment of the pipe cutting machine provided in the present application, the magnetic suction cup 3 includes a main body 31 and a plurality of carrier plates 32 .

[0050] The main body 31 is located in the feeding port and is rotatably connected to the base 1 via a rotating shaft.

[0051] Multiple carrier plates 32 are arranged around the periphery of the main body 31, each carrier plate 32 is connected to the main body 31 through a support rod 33, and each carrier plate 32 is provided with multiple electromagnetic plates 321, which are used to generate magnetic force when energized; the number of carrier plates 32 can be adjusted according to the feeding speed, and the electromagnetic plate 321 is connected to the multiple carrier plates 32 in a detachable manner, which is convenient for maintenance and replacement of the electromagnetic plate 321.

[0052] By adopting the above technical solution, the electromagnets on multiple carrier plates 32 can be used to realize multi-station unloading, thereby improving the processing efficiency of the pipe cutting machine and avoiding the accumulation of the tube blanks 9 on the guide plate 11 due to too slow unloading speed.

[0053] In some embodiments, please refer to Figures 1 to 4As a specific embodiment of the pipe cutting machine provided in the present application, the end of the carrier plate 32 away from the main body 31 has an arcuate surface for fitting with the outer wall of the tube blank 9, and a plurality of electromagnetic plates 321 are also provided on the arcuate surface; the arcuate surface includes a docking section which is radially perpendicular to the main body 31 and is tangent to the outer wall of the steel pipe 8, and a curved section with a certain radius fitting with the outer wall of the steel pipe 8, and the arcuate surface of each carrier plate 32 faces the same direction.

[0054] By adopting the above technical solution, the arc surface can increase the contact area between the carrier plate 32 and the tube blank 9, so that the carrier plate 32 can better adsorb the tube blank 9, and can avoid the tube blank 9 from deflecting after the carrier plate 32 adsorbs the tube blank 9; when the main body 31 drives multiple carrier plates 32 to rotate, the docking section first abuts against the outer wall of the steel pipe 8, and then the bending section abuts against the outer wall of the steel pipe 8, that is, the magnetic suction cup 3 reaches the first position. This setting enables the staff to better position when adjusting the magnetic suction cup 3.

[0055] In some embodiments, see Figures 1 to 3 As a specific embodiment of the pipe cutting machine provided in the present application, the cutting assembly 2 includes a first telescopic member 22 and a cutting saw 21 .

[0056] The first telescopic member 22 is fixedly arranged above the base 1 and is suitable for telescoping in the up-and-down direction; the first telescopic member 22 may be a linear air cylinder or a linear oil cylinder.

[0057] The cutting saw 21 is rotatably disposed at the lower end of the first telescopic member 22 and is transmission-connected to a rotating motor 23 .

[0058] By adopting the above technical solution and controlling the first telescopic member 22 , the automatic cutting of the cutting saw 21 can be achieved, saving time and effort.

[0059] In some embodiments, please refer to Figures 1 to 5 As a specific embodiment of the pipe cutting machine provided in the present application, the pipe cutting machine also includes a plurality of support members 4.

[0060] A plurality of support members 4 are arranged in parallel on the upper side of the base 1 along the front-to-back direction, and each support member 4 has a groove 41 for the steel pipe 8 to be embedded and passing through along the front-to-back direction.

[0061] By adopting the above technical solution, the multiple support members 4 can ensure that the steel pipe 8 always moves in a straight line along the front-to-back direction during cutting without left-right deviation, thereby improving the cutting quality of the steel pipe 8.

[0062] In some embodiments, please refer to Figures 1 to 5As a specific embodiment of the pipe cutting machine provided in the present application, a plurality of rollers 42 are provided in the groove 41; wherein the axial direction of each roller 42 is perpendicular to the front-rear direction, and is connected to the support member 4 for rotation along its own axial direction.

[0063] When the steel pipe 8 is embedded in the groove 41 , each roller 42 is suitable for abutting against the outer wall of the steel pipe 8 .

[0064] By adopting the above technical solution and arranging a plurality of rollers 42 in the groove 41 , a sliding connection between the steel pipe 8 and the support member 4 can be achieved, which saves more effort when pushing the steel pipe 8 toward the cutting assembly 2 .

[0065] In some embodiments, please refer to Figure 1 to Figure 2 As a specific embodiment of the pipe cutting machine provided in the present application, a limiting plate 5 for abutting against the cut end of the steel pipe 8 is also provided on the upper side of the base 1; the limiting plate 5 has reinforcing ribs on the side away from the discharge port.

[0066] Each time cutting is performed, the length to be cut is determined by pushing the steel pipe 8 until it abuts against the limit plate 5. The cutting length can be adjusted by adjusting the position of the limit plate 5 along the front-to-back direction. By adopting the above technical solution, the work of measuring the cutting size each time is eliminated, and the cutting length of the steel pipe 8 can be quickly determined, saving time and effort.

[0067] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 6 As a specific implementation of the pipe cutting machine provided in the present application, the pipe cutting machine also includes a pressing block 6.

[0068] The pressing block 6 is disposed above the base 1 and is connected to the base 1 via a second telescopic member 62 so as to be adapted to move in the up-down direction relative to the base 1 until it abuts against the steel pipe 8 .

[0069] By adopting the above technical solution, the second telescopic member 62 can realize the up and down movement of the pressing block 6. When the steel pipe 8 abuts against the limiting plate 5, the second telescopic member 62 drives the pressing block 6 to move toward the steel pipe 8 until the pressing block 6 abuts against the steel pipe 8, thereby achieving the fixation of the steel pipe 8, limiting the forward and backward movement and rotation of the steel pipe 8, and improving the cutting quality of the steel pipe 8; after the steel pipe 8 completes one cutting, the second telescopic member 62 drives the pressing block 6 to move back to the steel pipe 8 to release the steel pipe 8.

[0070] In some embodiments, see Figure 6 As a specific embodiment of the pipe cutting machine provided in the present application, the lower side of the pressing block 6 has a V-shaped groove for partially embedding the steel pipe 8.

[0071] By adopting the above technical solution, when the second telescopic member 62 drives the pressing block 6 to move toward the steel pipe 8, the inclined surface 61 of the V-shaped groove is suitable for first abutting against the outer wall of the steel pipe 8. When the pressing block 6 applies pressure to the steel pipe 8, compared with the existing flat-plate pressing block 6, the pressing block 6 can have more force application points, so that the steel pipe 8 is fixed more reliably; at the same time, it also avoids the steel pipe 8 from detaching from the bottom of the pressing block 6 when the pressing block 6 applies force and deflects.

[0072] In some embodiments, please refer to Figure 1 and Figure 3 As a specific embodiment of the pipe cutting machine provided in the present application, the bottom of the aggregate box 7 has a plurality of casters 71; the casters 71 can adopt fixable universal wheels, and when the aggregate box 7 is pushed to the bottom of the base 1 and connected to the guide plate 11, the position of the aggregate box 7 can be fixed by locking the plurality of casters 71.

[0073] By adopting the above technical solution, the aggregate box 7 can be easily transferred. By setting up multiple aggregate boxes 7, the staff can quickly replace the aggregate boxes 7 during batch production, thereby improving the cutting production efficiency of the steel pipe 8.

[0074] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
