[0002] The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of oil in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after World War II, the development of the chemical industry, and the drilling and transportation of oil and natural gas, all of which have strongly promoted the development of the steel pipe industry in terms of variety, output, and quality. Steel pipes need to be cut before use. Among the existing cutting technologies, laser cutting is the most advanced and has the best cutting effect.

[0003] At present, steel pipes are indispensable materials for industrial production, construction and other industries. The processed steel pipes need to be cut into different lengths. When accurately positioning and adjusting the steel pipes in the existing laser cutting machine, it is not convenient to adjust the position because the steel pipes are fixed on the machine tool by clamping. Summary of the invention

[0008] The adjusting assembly is fixedly mounted on the top of the frame through a support, and the surface of the adjusting assembly on the side away from the positioning assembly passes through the frame and extends into the interior thereof, and the positioning assembly is fixedly mounted at the top edge of the frame; the staff places the steel pipe in the positioning assembly, and then starts the adjusting assembly, so that the adjusting assembly drives the cutting assembly to rotate on the support, so that the cutting assembly is adjusted to contact the steel pipe to cut the steel pipe.

[0009] The adjustment assembly includes a through column, which extends through the frame to the inside thereof, a hinge plate is rotatably mounted on the top of the through column, a shell is fixedly mounted on the outer surface of the hinge plate, a positioning block is fixedly mounted between opposite surfaces of the shell, the positioning block is arranged on the outer surface of the cutting assembly, a rotating block is fixedly mounted on the bottom of the positioning block, and the rotating block is rotatably mounted inside the support. The staff starts the cutting machine to rotate the hinge plate on the through column, so that the hinge plate drives the shell to rise and fall, and the positioning block drives the rotating block to rotate in the support, so that the cutting assembly rotates to the surface of the steel pipe along with the positioning block, so as to adjust the angle of the cutting assembly.

[0010] Preferably, the cutting assembly comprises a limit block, the limit block is fixedly mounted on the top of the positioning block, a fixed shaft is fixedly mounted on the bottom of the limit block, and a cutting head is fixedly mounted on the bottom of the fixed shaft.

[0011] Preferably, the positioning assembly includes a positioning plate, the positioning plate is fixedly installed at the middle of the top of the frame, and a bending frame is arranged on the top of the positioning plate, and two bending frames are arranged symmetrically with the positioning plate as the center. The staff places the steel pipe in the buffer assembly, and sleeves it on the surface of the pipe-piercing piece to fix the steel pipe, so that the buffer assembly is clamped on the outer wall of the steel pipe, so that the steel pipe is fixed from the inside and outside by the pipe-piercing piece and the buffer assembly, so as to avoid displacement of the steel pipe during cutting.

[0012] Preferably, fixing blocks are fixedly installed on both sides of the outer surface of the bending frame, and the fixing blocks are fixedly installed at the top edge of the positioning plate.

[0013] Preferably, a buffer assembly is fixedly installed between the opposite surfaces of the bending frame, a connecting frame is fixedly installed on the top of the buffer assembly, a spray pipe is fixedly installed on the top of the connecting frame, a central axis is fixedly installed inside the bending frame, and a pipe-through fitting is slidably installed at the axis of the central axis. The spray pipe arranged on the top of the connecting frame is connected to the chip removal liquid through the pipeline, which cools the cutting point during cutting, cleans the chips generated during cutting, avoids the chips from sticking, and sprays the chips with liquid during cutting to avoid the chips from splashing everywhere and affecting the processing environment.

[0014] Preferably, the pipe-threading member includes a support tube, and a staggered rod is fixedly installed on the outer surface of the support tube. The staggered rod is provided in two groups, and the two groups of staggered rods are symmetrically arranged on the outer surface of the support tube. A bonding plate is fixedly installed on the surface of the staggered rod away from the support tube. The staff sleeves the steel pipe on the surface of the bonding plate so that the bonding plate is bonded to the inner wall of the steel pipe, and then the staff pushes the extension rod to slide in the central axis of the extension rod, and drives the circular plate, the bonding plate and the steel pipe sleeved on its surface to push toward the middle of the positioning assembly.

[0015] Preferably, a circular plate is fixedly mounted on the surface of the support tube close to the central axis, an extension rod is passed through the interior of the circular plate, and the extension rod passes through the central axis and extends to its surface, and a clamp is fixedly mounted on the outer surface of the extension rod. After the cutting is completed, the staff pulls the extension rod outward. Since the steel pipe is divided into two sections after cutting, the staff pulls the extension rods on both sides, and the bonding plates on both sides slide on the inner wall of the steel pipe as the extension rods move, so that the bonding plates are gradually pulled out of the steel pipe. When the bonding plates are pulled out, the steel pipe loses its internal support and only relies on the clamping clamp of the arc-shaped kit arranged above the positioning plate, which is convenient for fixing steel pipes of different lengths.

The steel pipe is sleeved on the surface of the bonding plate, and is pushed and moved to the middle of the arc-shaped kit by the extension rod, and is clamped by the clamping frame. After the cutting is completed, the staff will pull out the bonding plate. At this time, when the steel pipe is clamped between the clamping frames, the staff pulls the connecting plate so that the connecting plate drives the outer clamping frame to move outward, so that the steel pipe loses the clamping and falls from the clamping frame to the inclined plate and slides downward along the inclined angle of the inclined plate, and is separated from the buffer assembly, so as to facilitate the removal of the steel pipe after cutting.

[0018] Preferably, a connecting rod is fixedly installed on one side of the clamping frame close to the bending frame, a spring is sleeved on the surface of the connecting rod, and a connecting plate is fixedly installed between opposite surfaces of the connecting rod.

[0019] The present invention provides a laser cutting machine for cutting steel pipes, which has the following beneficial effects:

[0020] 1. The laser cutting machine used to cut the steel pipe is that the staff puts the steel pipe on the surface of the bonding plate so that the bonding plate is bonded to the inner wall of the steel pipe, and then the staff pushes the extension rod to make the extension rod slide inside the central axis, and drive the circular plate, the bonding plate and the steel pipe sleeved on its surface to the middle of the positioning assembly. At this time, the clamping ring set on the surface of the extension rod moves to the outside of the central axis, and limits the extension rod, so that the cutting part of the steel pipe moves to the bottom of the cutting head, and the cutting head cuts the steel pipe.

[0021] 2. The laser cutting machine used to cut the steel pipe, after the cutting is completed, the staff pulls the extension rod outward. Since the steel pipe is divided into two sections after cutting, the staff pulls the extension rods on both sides, and the bonding plates on both sides slide on the inner wall of the steel pipe as the extension rods move, so that the bonding plates are gradually pulled out of the steel pipe. When the bonding plates are pulled out, the steel pipe loses its internal support and only relies on the clamping clamp of the arc kit arranged above the positioning plate, which is convenient for fixing steel pipes of different lengths. For two sections of steel pipes of different lengths, the position of the steel pipe in the buffer assembly is adjusted according to the cutting position.

[0022] 3. The laser cutting machine used to cut the steel pipe is set on the surface of the bonding plate through the steel pipe sleeve, and is pushed to the middle of the arc-shaped kit by the extension rod and clamped by the clamping frame. After the cutting is completed, the staff will pull out the bonding plate. At this time, the steel pipe is clamped between the clamping frames. The staff pulls the connecting plate so that the connecting plate drives the outer clamping frame to move outward, so that the steel pipe loses the clamping and falls from the clamping frame to the inclined plate and slides downward along the inclination angle of the inclined plate, and detaches from the buffer assembly, so as to facilitate the removal of the steel pipe after cutting.

[0023] 4. The laser cutting machine used to cut the steel pipe is started by a staff member to rotate the hinge plate on the through column, so that the hinge plate drives the outer shell to rise and fall, and the positioning block drives the rotating block to rotate in the support, so that the cutting component rotates to the surface of the steel pipe with the positioning block, so as to adjust the angle of the cutting component.

[0024] 5. The laser cutting machine used to cut the steel pipe is connected to the chip removal liquid through the pipeline through the spray pipe arranged on the top of the connecting frame. The cutting point is cooled during cutting, and the debris generated during cutting is cleaned to avoid the debris sticking. The debris is sprayed with liquid during cutting to avoid the debris splashing everywhere and affecting the processing environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The adjustment assembly 3 includes a through column 33, which extends through the frame 1 to the inside thereof, a hinge plate 32 is rotatably mounted on the top of the through column 33, a housing 31 is fixedly mounted on the outer surface of the hinge plate 32, a positioning block 35 is fixedly mounted between opposite surfaces of the housing 31, the positioning block 35 is arranged on the outer surface of the cutting assembly 4, a rotating block 34 is fixedly mounted on the bottom of the positioning block 35, and the rotating block 34 is rotatably mounted inside the support 2. The staff starts the cutting machine to rotate the hinge plate 32 on the through column 33, so that the hinge plate 32 drives the housing 31 to rise and fall, so that the positioning block 35 drives the rotating block 34 to rotate in the support 2, so that the cutting assembly 4 rotates to the surface of the steel pipe along with the positioning block 35, so as to adjust the angle of the cutting assembly 4.

[0042] The cutting assembly 4 comprises a limit block 41 , which is fixedly mounted on the top of the positioning block 35 , a fixed shaft 42 is fixedly mounted on the bottom of the limit block 41 , and a cutting head 43 is fixedly mounted on the bottom of the fixed shaft 42 .

[0043] The second embodiment is based on the first embodiment. Figures 4 to 7As shown, the positioning assembly 5 includes a positioning plate 51, which is fixedly mounted at the middle of the top of the frame 1. A bending frame 53 is arranged on the top of the positioning plate 51. Two bending frames 53 are arranged, and the two bending frames 53 are symmetrically arranged with the positioning plate 51 as the center. The staff places the steel pipe in the buffer assembly 54, and sleeves it on the surface of the pipe-piercing member 52 to fix the steel pipe, so that the buffer assembly 54 is clamped on the outer wall of the steel pipe, so that the steel pipe is fixed from the inside and outside by the pipe-piercing member 52 and the buffer assembly 54, so as to avoid displacement of the steel pipe during cutting.

[0044] Fixed blocks 56 are fixedly installed on both sides of the outer surface of the bending frame 53 , and the fixed blocks 56 are fixedly installed at the top edge of the positioning plate 51 .

[0045] A buffer assembly 54 is fixedly installed between the opposite surfaces of the bending frame 53, a connecting frame 55 is fixedly installed on the top of the buffer assembly 54, a spray pipe 58 is fixedly installed on the top of the connecting frame 55, a central shaft 57 is fixedly installed inside the bending frame 53, and a pipe-through fitting 52 is slidably installed at the axis of the central shaft 57. The spray pipe 58 arranged on the top of the connecting frame 55 is connected to the chip removal liquid through the pipeline, which cools the cutting point during cutting, cleans the chips generated during cutting, and prevents the chips from sticking, and sprays the chips with liquid during cutting to prevent the chips from splashing everywhere and affecting the processing environment.

[0046] The pipe-piercing member 52 includes a support tube 523, and a staggered rod 522 is fixedly installed on the outer surface of the support tube 523. The staggered rod 522 is provided with two groups, and the two groups of staggered rods 522 are symmetrically arranged on the outer surface of the support tube 523. The surface of the staggered rod 522 away from the support tube 523 is fixedly installed with a bonding plate 521. The staff sleeves the steel pipe on the surface of the bonding plate 521, so that the bonding plate 521 is bonded to the inner wall of the steel pipe, and then the staff pushes the extension rod 525 to slide in the central axis 57 of the extension rod 525, and drives the circular plate 524, the bonding plate 521 and the steel pipe sleeved on the surface thereof to push toward the middle of the positioning assembly 5. At this time, the clamping ring 526 provided on the surface of the extension rod 525 moves to the outside of the central axis 57, and limits the extension rod 525, so that the cutting part of the steel pipe moves below the cutting head 43, and the cutting head 43 cuts the steel pipe.

[0047] A circular plate 524 is fixedly installed on the surface of the support tube 523 near the central axis 57, and an extension rod 525 is passed through the inside of the circular plate 524, and the extension rod 525 passes through the central axis 57 and extends to its surface, and a clamping ring 526 is fixedly installed on the outer surface of the extension rod 525. After the cutting is completed, the staff pulls the extension rod 525 outward. Since the steel pipe is cut into two sections, the staff pulls the extension rods 525 on both sides, and the bonding plates 521 on both sides slide on the inner wall of the steel pipe as the extension rods 525 move, so that the bonding plates 521 are gradually pulled out of the steel pipe. When the bonding plates 521 are pulled out, the steel pipe loses its internal support and only relies on the clamping clamp of the arc kit 543, which is arranged above the positioning plate 51, so as to facilitate the fixing of steel pipes of different lengths, and adjust the position of the steel pipe in the buffer assembly 54 according to the cutting position for the two sections of steel pipes of different lengths.

[0048] The third embodiment is based on the first and second embodiments. Figures 8 to 9 As shown, the buffer assembly 54 includes a cross frame 541, which is fixedly installed between the opposite surfaces of the curved frame 53, an extension frame 542 is fixedly installed on the top of the cross frame 541, an arc-shaped kit 543 is fixedly installed on the outer surface of the extension frame 542, and a connecting rod 544 is fixedly installed on the top of the arc-shaped kit 543.

[0049] The arc-shaped kit 543 includes a curved frame 5433, a clamping frame 5434 is fixedly installed inside the curved frame 5433, an inclined sheet 5435 is fixedly installed at the bottom of the curved frame 5433, and two groups of clamping frames 5434 are provided, and the two groups of clamping frames 5434 are respectively arranged on both sides of the curved frame 5433. The steel pipe is sleeved on the surface of the bonding plate 521, and is pushed and moved to the middle of the curved kit 543 by the extension rod 525, and is clamped by the clamping frame 5434. After the cutting is completed, the staff will pull out the bonding plate 521. At this time, the steel pipe is clamped between the clamping frames 5434. The staff pulls the connecting plate 5431 so that the connecting plate 5431 drives the outer clamping frame 5434 to move outward, so that the steel pipe loses the clamping and falls from the clamping frame 5434 to the inclined sheet 5435 and slides downward along the inclined angle of the inclined sheet 5435, and is separated from the buffer assembly 54, so that the steel pipe can be taken out after cutting.

[0050] A connecting rod 5432 is fixedly installed on one side of the clamping frame 5434 close to the bending frame 5433 . A spring 5436 is sleeved on the surface of the connecting rod 5432 . A connecting plate 5431 is fixedly installed between opposite surfaces of the connecting rod 5432 .

[0051] When in use, the staff places the steel pipe in the positioning assembly 5, and then the staff starts the adjustment assembly 3, so that the adjustment assembly 3 drives the cutting assembly 4 to rotate on the support 2, so that the cutting assembly 4 is adjusted to contact the steel pipe to cut the steel pipe.

[0052] The staff starts the cutting machine to make the hinge plate 32 rotate on the through column 33, so that the hinge plate 32 drives the shell 31 to rise and fall, and the positioning block 35 drives the rotating block 34 to rotate in the support 2, so that the cutting component 4 rotates to the surface of the steel pipe with the positioning block 35, so as to adjust the angle of the cutting component 4.

[0053] The staff places the steel pipe in the buffer assembly 54 and puts it on the surface of the pipe-piercing member 52 to fix the steel pipe, so that the buffer assembly 54 is clamped on the outer wall of the steel pipe, so that the steel pipe is fixed from the inside and outside by the pipe-piercing member 52 and the buffer assembly 54 to avoid displacement of the steel pipe during cutting.

[0054] The spray pipe 58 arranged on the top of the connecting frame 55 is connected to the chip removal liquid through the pipeline, which cools the cutting point during cutting, cleans the chips generated during cutting to prevent the chips from sticking together, and sprays the chips with liquid during cutting to prevent the chips from splashing everywhere and affecting the processing environment.

[0055] The staff sleeves the steel pipe on the surface of the bonding plate 521 so that the bonding plate 521 fits the inner wall of the steel pipe, and then the staff pushes the extension rod 525 to make the extension rod 525 slide inside the central axis 57, and drive the circular plate 524, the bonding plate 521 and the steel pipe sleeved on its surface to push toward the middle of the positioning assembly 5. At this time, the retaining ring 526 set on the surface of the extension rod 525 moves to the outside of the central axis 57 and limits the extension rod 525, so that the cutting part of the steel pipe moves toward the bottom of the cutting head 43, and the cutting head 43 cuts the steel pipe.

[0056] After the cutting is completed, the staff pulls the extension rod 525 outward. Since the steel pipe is divided into two sections after cutting, the staff pulls the extension rods 525 on both sides, and the bonding plates 521 on both sides slide on the inner wall of the steel pipe as the extension rods 525 move, so that the bonding plates 521 are gradually pulled out of the steel pipe. When the bonding plates 521 are pulled out, the steel pipe loses its internal support and only relies on the clamping clamp of the arc kit 543 arranged above the positioning plate 51, which is convenient for fixing steel pipes of different lengths. For two sections of steel pipes of different lengths, the position of the steel pipe in the buffer assembly 54 is adjusted according to the cutting position.

[0057] The steel pipe is sleeved on the surface of the bonding plate 521, and is pushed by the extension rod 525 to move to the middle of the arc-shaped kit 543, and is clamped by the clamping frame 5434. After the cutting is completed, the staff will pull out the bonding plate 521. At this time, the steel pipe is clamped between the clamping frames 5434. The staff pulls the connecting plate 5431 so that the connecting plate 5431 drives the outer clamping frame 5434 to move outward, so that the steel pipe loses its clamping and falls from the clamping frame 5434 to the inclined piece 5435 and slides downward along the inclination angle of the inclined piece 5435, and detaches from the buffer assembly 54, so as to facilitate the removal of the steel pipe after cutting.
