[0002] Steel pipe cutting machine is a mechanical equipment used to cut metal pipes. It is usually composed of cutting tools, transmission system, control system and workbench. Among them, laser cutting machine is a common steel pipe cutting equipment.

[0003] In the past, when steel pipe cutting machines were working, the steel pipe was clamped and kept fixed, and the entire steel pipe was cut through a laser cutting head, which was energy-consuming. In addition, this cutting method required different cutting thicknesses in the radial direction of the steel pipe, resulting in poor uniformity in cutting the steel pipe. Summary of the invention

[0004] In view of the problems in the prior art, the utility model provides a steel pipe cutting machine. The steel pipe can be rotated after being clamped, and the laser cutting head only needs to cut through the wall thickness of the steel pipe, which is more energy-saving. In addition, the wall thickness of each part that needs to be cut through when cutting the steel pipe is consistent, and the uniformity of the steel pipe cutting is better.

[0005] The technical solution adopted by the utility model to solve its technical problems is a steel pipe cutting machine, comprising a base, a vertical plate, a clamping mechanism, a displacement mechanism, a support plate, a top plate and a laser cutting head, wherein the displacement mechanism is composed of a second servo motor, a wire block, a guide groove and a second mounting plate, a screw rod is connected to the power output end of the second servo motor, a wire block is sleeved on the outer side of the screw rod, a second mounting plate is connected to the bottom of the wire block, and a laser cutting head is installed on the bottom of the second mounting plate by bolts;

[0006] The clamping mechanism consists of a circular rotating block, an adjusting stud, a rectangular slide groove, a rectangular sliding block and a clamping groove. The top and bottom of the circular rotating block are provided with adjusting studs through threaded grooves. A shaft sleeve is provided on the periphery of the end of the adjusting stud. The end of the shaft sleeve is connected to a rectangular sliding block. The rectangular sliding block is located in the rectangular slide groove. Clamping grooves are provided at the adjacent parts of the two groups of rectangular sliding blocks. Vertical plates are provided on both sides of the top of the base.

A driven gear is provided at the periphery of the circular rotating block near one side, and the driven gear is meshed with the driving gear.

[0007] By adopting the above technical scheme, the vertical plate can be driven to rotate by rotating the adjusting stud, so that the rectangular sliding block can be lifted and lowered along the inner wall of the rectangular sliding groove. The clamping groove is opened between the two groups of rectangular sliding blocks to facilitate clamping of the steel pipe. The power output end of the first servo motor can drive the driving gear to rotate, so that the driven gear meshing with the driving gear rotates, and then the clamped steel pipe is driven to rotate. The second servo motor drives the lead screw to rotate, so that the second mounting plate and the laser cutting head move horizontally. The rotating steel pipe can be cut by the laser cutting head. Since the steel pipe can be rotated after being clamped, the laser cutting head only needs to cut through the wall thickness of the steel pipe, which is more energy-saving. In addition, the wall thickness of each part that needs to be cut through when cutting the steel pipe is consistent, and the uniformity of the steel pipe cutting is better.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In order to allow the steel pipe to rotate after being clamped, the laser cutting head only needs to cut through the wall thickness of the steel pipe, which is more energy-saving. In addition, the wall thickness of each part that needs to be cut through when cutting the steel pipe is consistent, which improves the uniformity of the steel pipe cutting. Figure 1-3 As shown, a steel pipe cutting machine described in the utility model includes a base 1, a vertical plate 2, a clamping mechanism, a displacement mechanism, a support plate 19, a top plate 20 and a laser cutting head 27, wherein the displacement mechanism is composed of a second servo motor 21, a wire block 23, a guide groove 25 and a second mounting plate 26, wherein a screw rod 24 is connected to the power output end of the second servo motor 21, a wire block 23 is sleeved on the outer side of the screw rod 24, a second mounting plate 26 is connected to the bottom of the wire block 23, and a laser cutting head 27 is installed at the bottom of the second mounting plate 26 by bolts;

[0022] The clamping mechanism consists of a circular rotating block 10, an adjusting stud 13, a rectangular slide groove 14, a rectangular sliding block 15 and a clamping groove 16. The top and bottom of the circular rotating block 10 are both provided with adjusting studs 13 through threaded grooves. The end of the adjusting stud 13 is provided with a shaft sleeve 28 on the periphery. The end of the shaft sleeve 28 is connected with a rectangular sliding block 15. The rectangular sliding block 15 is located in the rectangular slide groove 14. The two groups of rectangular sliding blocks 15 are provided with clamping grooves 16 near each other. Vertical plates 2 are provided on both sides of the top of the base 1. A first mounting plate 3 is provided on one side of the vertical plate 2. A first servo motor 4 is provided on the top of the first mounting plate 3 through a fixed seat. A driving gear 5 is connected to the power output end of the first servo motor 4. A driven tooth 12 is provided near one side of the periphery of the circular rotating block 10, and the driven tooth 12 is meshed with the driving gear 5.

[0023] When in use, by rotating the adjusting stud 13, the vertical plate 2 is conveniently driven to rotate, so that the rectangular sliding block 15 is lifted and moved along the inner wall of the rectangular sliding groove 14. A clamping groove 16 is opened between the two groups of rectangular sliding blocks 15 to facilitate clamping of the steel pipe. The power output end of the first servo motor 4 can drive the driving gear 5 to rotate, so that the driven tooth 12 meshing with the driving gear 5 rotates, and then the clamped steel pipe is conveniently driven to rotate. The second servo motor 21 drives the screw rod 24 to rotate, so that the second mounting plate 26 and the laser cutting head 27 move horizontally. The laser cutting head 27 can be used to cut the rotating steel pipe. Since the steel pipe can be rotated after being clamped, the laser cutting head only needs to cut through the wall thickness of the steel pipe, which is more energy-saving. In addition, the wall thickness of each part that needs to be cut through when cutting the steel pipe is consistent, and the uniformity of the steel pipe cutting is better.

[0024] For example, Figure 1-3 As shown, the utility model also includes that a limiting groove 11 is opened on the periphery of the circular rotating block 10 away from the side of the driven tooth 12, a fixed block 6 is arranged near the center of the top of the base 1, a bearing 7 is arranged on one side of the fixed block 6 through a reserved groove, a rotating shaft 8 is sleeved in the bearing 7, guide rollers 9 are arranged on the periphery of both ends of the rotating shaft 8, and the guide rollers 9 are located in the limiting groove 11.

[0025] For example, Figure 1-2 As shown, the utility model also includes that a support plate 19 is arranged on the top of the vertical plate 2, and the top of the support plate 19 is connected to a top plate 20, a vertical plate 22 is arranged on the bottom of the top plate 20 away from the side of the second servo motor 21, a limiting groove is arranged on one side of the vertical plate 22, the end of the screw rod 24 is located in the limiting groove, a guide groove 25 is arranged near the center of the bottom of the top plate 20, and the top of the wire block 23 is located in the guide groove 25.

[0026] When in use, the guide groove 25 limits and guides the thread block 23 , so that when the screw rod 24 rotates, it can only drive the thread block 23 to move horizontally along the guide groove 25 .

[0027] For example, Figure 1-2 As shown, the utility model also includes that a vertical pole 17 is arranged near a corner on the top of the base 1, and a PLC controller 18 is fixed to one side of the top of the vertical pole 17 through a connecting rod.

[0028] When in use, the second servo motor 21 , the laser cutting head 27 and the first servo motor 4 are conveniently controlled by the PLC controller 18 .

[0029] For example, Figure 1-2 As shown, the utility model also includes that a foot pad is arranged near the corner at the bottom of the base 1.

[0030] When in use, the bottom of the base 1 can be conveniently raised and protected by the foot pad.

[0031] For example, Figure 3 As shown, the utility model also includes that the inner wall of the clamping groove 16 is provided with a wear-resistant layer, and the wear-resistant layer is made of ceramic material.

[0032] When in use, the wear-resistant layer made of ceramic material can effectively increase the service life of the clamping groove 16 .

[0033] When the utility model is in use, the second servo motor 21, the laser cutting head 27 and the first servo motor 4 are conveniently controlled by the PLC controller 18. The second servo motor 21 drives the screw rod 24 to rotate, so that the wire block 23 moves horizontally along the direction of the guide groove 25, thereby making the second mounting plate 26 and the laser cutting head 27 move horizontally, so as to facilitate the adjustment of the horizontal position of the laser cutting head 27 along the direction of the guide groove 25.

[0034] By rotating the adjusting stud 13, the vertical plate 2 can be driven to rotate conveniently, so that the rectangular sliding block 15 can be lifted and moved along the inner wall of the rectangular slide groove 14. A clamping groove 16 is provided between the two groups of rectangular sliding blocks 15 to facilitate clamping of the steel pipe. The power output end of the first servo motor 4 can drive the driving gear 5 to rotate, so that the driven gear 12 meshing with the driving gear 5 can rotate, and then the clamped steel pipe can be driven to rotate conveniently. The second servo motor 21 drives the screw rod 24 to rotate, so that the second mounting plate 26 and the laser cutting head 27 can be moved horizontally. The laser cutting head 27 can be used to cut the rotating steel pipe. Since the steel pipe can be rotated after being clamped, the laser cutting head only needs to cut through the wall thickness of the steel pipe, which is more energy-saving. In addition, the wall thickness of each part that needs to be cut through when cutting the steel pipe is consistent, and the uniformity of the steel pipe cutting is better.
