Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cutting device for metal processing. Background Art

[0002] Metal steel pipes often need to be cut during the processing. When a long steel pipe needs to be cut into multiple sections, it is necessary to move it along the axis for a certain distance before cutting. When a steel pipe with a larger diameter needs to be cut and the cutting knife is difficult to cut it directly, the steel pipe needs to be rotated. However, in the traditional operation method, moving the steel pipe along the axis and rotating the steel pipe are usually performed manually, which is very time-consuming and labor-intensive.

[0003] For example, a Chinese utility model patent disclosed in the Chinese patent publication with publication number CN114309773A and authorization announcement date April 12, 2022 discloses a bearing steel pipe cutting device; the bearing steel pipe cutting device includes a matching seat, a limiting seat and a cutting piece, the limiting seat includes a closing sleeve, a plurality of limiting units, a central shaft rod and a support, the closing sleeve is arranged on the upper side of the support and is fixedly connected to the support, the plurality of limiting units are arranged on the upper and lower sides of the interior of the closing sleeve, and the plurality of limiting units are slidably connected to the closing sleeve, the central shaft rod is arranged along the length extension direction of the closing sleeve, and the central shaft rod is slidably connected to the plurality of limiting units,

[0004] However, in actual use, the above-mentioned device sets the limiting seat on the inner wall of the steel pipe through the design of the limiting unit and the closing sleeve, so as to meet the automatic fixing and loosening of the steel pipe, but the device cannot drive the steel pipe to move along the axial direction, nor can it drive the steel pipe to rotate. Therefore, when cutting longer steel pipes or steel pipes with larger diameters, it is necessary to manually drive the steel pipe to move along the axial direction or to rotate the steel pipe, which is very time-consuming and labor-intensive. Utility Model Content

[0005] The utility model aims to provide a cutting device for metal processing, so as to solve the problem that the existing cutting device is inconvenient to drive the steel pipe to move along the axial direction and to rotate the steel pipe.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting device for metal processing, comprising a base, a support frame is provided at one end of the base, three support rollers are rotatably connected to the top of the support frame, first cylinders are provided at both ends of the support frame, a second cylinder is provided at the output end of the first cylinder, a first motor is provided at the output end of the second cylinder, a roller is provided at the output end of the first motor, a ring is provided at the base adjacent to the support frame, a sleeve is rotatably connected to the inner wall of the ring, four third cylinders are provided in the sleeve, a splint is provided at the output end of the third cylinder, a second motor is provided on the top of the ring, and the output end of the second motor is meshed with the sleeve.

[0011] Preferably, the base is located at one end of the support table and is fixedly connected to a fixing frame, the fixing frame is located directly above the cutting table and is fixedly connected to a third hydraulic cylinder, and a cutting knife is installed at the output end of the third hydraulic cylinder.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model drives the roller to move toward the steel pipe through the second cylinder, so that the two rollers clamp the two ends of the steel pipe, and drives the roller to rotate through the first motor. The roller will drive the steel pipe to move during the rotation process, so that the steel pipe can be moved along the axial direction.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-3 The utility model provides a technical solution: a cutting device for metal processing, comprising a base 1, a support frame 2 is arranged at one end of the base 1, three support rollers 3 are rotatably connected to the top of the support frame 2, first cylinders 4 are arranged at both ends of the support frame 2, a second cylinder 5 is arranged at the output end of the first cylinder 4, a first motor 6 is arranged at the output end of the second cylinder 5, a roller 7 is arranged at the output end of the first motor 6, a collar 8 is arranged at the base 1 adjacent to the support frame 2, a sleeve 9 is rotatably connected to the inner wall of the collar 8, four third cylinders 10 are arranged in the sleeve 9, a clamping plate 11 is arranged at the output end of the third cylinder 10, a second motor 12 is arranged at the top of the collar 8, and the output end of the second motor 12 is meshed and connected with the sleeve 9,

[0020] In this embodiment, when it is necessary to drive the steel pipe to move along the axial direction, the third cylinder 10 is first opened to drive the clamping plate 11 away from the steel pipe, and the second cylinder 5 is opened to drive the roller 7 to move toward the steel pipe, so that the two rollers 7 clamp the steel pipe, wherein the first cylinder 4 can drive the roller 7 to move up and down, so that the two rollers 7 can clamp the middle of both sides of the steel pipe, so that the steel pipe can be clamped more stably, and the first motor 6 can be turned on at this time. The roller 7 will rotate under the drive of the first motor 6, thereby driving the steel pipe to move, so as to achieve the steel pipe. The pipe moves along the axial direction, and is rotatably connected with the support frame 2 through the support roller 3 so that the steel pipe will not encounter too much resistance when moving. When it is necessary to cut a steel pipe with a larger diameter, it is necessary to drive the steel pipe to rotate while cutting. At this time, the third cylinder 10 is first turned on to drive the clamp 11 to clamp the steel pipe, and then the second motor 12 is turned on. Since the output end of the second motor 12 is meshed and connected with the sleeve 9, the sleeve 9 will be driven to rotate after the second motor 12 is turned on, thereby driving the steel pipe to rotate, and the steel pipe can be smoothly cut off.

[0021] The base 1 is located below the support frame 2 and is fixedly connected to two first hydraulic cylinders 13. The output end of the first hydraulic cylinder 13 is fixedly connected to the support frame 2. In the present embodiment, since the diameters of the cut steel pipes are different, when the clamping plate 11 clamps the steel pipe, the distance between the bottom of the steel pipe and the base 1 will be different. At this time, the height of the support roller 3 must be adjusted. Therefore, the support roller 3 can be driven up and down by the first hydraulic cylinder 13 to adjust the height of the support roller 3.

[0022] The output end of the second cylinder 5 is fixedly connected with a connecting frame 14, the connecting frame 14 is fixedly connected to the first motor 6, and the connecting frame 14 is rotatably connected to the roller 7. In this embodiment, the design of the connecting frame 14 allows the first motor 6 to be firmly installed on the output end of the second cylinder 5, and at the same time allows the roller 7 to be more stable when rotating.

[0023] The output end of the second motor 12 is fixedly connected to the first gear 15, and one end of the outer wall of the sleeve 9 is fixedly connected to the second gear 16. The first gear 15 is meshed with the second gear 16. In this embodiment, the design of the first gear 15 and the second gear 16 allows the output end of the second motor 12 to be smoothly meshed with the sleeve 9.

[0024] A second hydraulic cylinder 17 is fixedly connected to one end of the base 1 away from the support frame 2, and a cutting table 18 is fixedly connected to the output end of the second hydraulic cylinder 17. In the present embodiment, the design of the cutting table 18 can support the position of the steel pipe to be cut. In addition, since the diameters of the steel pipes to be cut are different, when the clamping plate 11 clamps the steel pipe, the distance between the bottom of the steel pipe and the base 1 will be different. At this time, the height of the cutting table 18 needs to be adjusted. Therefore, the cutting table 18 can be driven up and down by the second hydraulic cylinder 17, thereby adjusting the height of the cutting table 18.

[0025] The base 1 is located at one end of the support table and is fixedly connected to a fixing frame 19. The fixing frame 19 is located directly above the cutting table 18 and is fixedly connected to a third hydraulic cylinder 20. A cutting knife 21 is installed at the output end of the third hydraulic cylinder 20. In this embodiment, the steel pipe is cut by the design of the cutting knife 21, and the cutting knife 21 is driven to move up and down by the design of the third hydraulic cylinder 20, so that the cutting knife 21 can smoothly cut the steel pipe.

[0026] Working principle: When in use, first pass one end of the steel pipe through the sleeve 9 and place it on the cutting table 18, and the other end is placed on the support roller 3. Then open the third cylinder 10 to drive the clamping plate 11 to move toward the steel pipe, so as to clamp the steel pipe. At this time, the third hydraulic cylinder 20 can be opened to drive the cutting knife 21 to move downward, so as to cut the steel pipe. When it is necessary to drive the steel pipe to move along the axial direction, the third cylinder 10 is opened first to drive the clamping plate 11 away from the steel pipe, and at the same time The second cylinder 5 is turned on to drive the roller 7 to move toward the steel pipe, so that the two rollers 7 clamp the steel pipe. The first cylinder 4 can drive the roller 7 to move up and down, so that the two rollers 7 can clamp the middle of both sides of the steel pipe, so that the steel pipe can be clamped more stably. At this time, the first motor 6 can be turned on. The roller 7 will rotate under the drive of the first motor 6, thereby driving the steel pipe to move, so as to realize the movement of the steel pipe along the axial direction, wherein the support roller 3 is connected to the support frame 2 through rotation. Together, the steel pipe will not encounter too much resistance when moving. When it is necessary to cut a steel pipe with a larger diameter, the cutting knife 21 cannot directly cut the steel pipe. At this time, it is necessary to drive the steel pipe to rotate while cutting. At this time, the third cylinder 10 is first turned on, and the third cylinder 10 drives the clamping plate 11 to clamp the steel pipe. Then the second motor 12 is turned on. Under the drive of the second motor 12, the first gear 15 will rotate, thereby driving the second gear 16 to rotate, and then driving the sleeve 9 to rotate. When the sleeve 9 rotates, it can drive the steel pipe to rotate. At this time, the cutting knife 21 can cut the steel pipe smoothly. In addition, since the diameters of the cut steel pipes are different, when the clamping plate 11 clamps the steel pipe, the distance between the bottom of the steel pipe and the base 1 will be different. At this time, the height of the support roller 3 and the cutting table 18 must be adjusted. Therefore, the support roller 3 can be driven up and down by the first hydraulic cylinder 13, and the cutting table 18 can be driven up and down by the second hydraulic cylinder 17, thereby adjusting the height of the support roller 3 and the cutting table 18.
