Description

Technical Field

[0001] This invention relates to the field of steel pipe processing equipment technology, specifically to a seamless steel pipe cutting and grinding production line. Background Technology

[0002] Seamless steel pipes are hollow steel products manufactured by piercing and rolling solid billets. Their core characteristics are the absence of weld seams, a hollow cross-section, and high strength. Compared to solid steel products such as round bars, seamless steel pipes are lighter in weight while maintaining the same bending and torsional strength, making them a typical example of economical cross-section steel. Materials include carbon steel, alloy steel, and stainless steel. They can be categorized by shape into round and shaped pipes (such as square and oval), and further subdivided according to application into specialized types such as boiler tubes, geological pipes, and oil pipes.

[0003] During the production of seamless steel pipes, they need to be cut and their end faces are ground. Generally, the seamless steel pipe is clamped and then cut by pushing the cutting mechanism downward. After the cutting is completed, the cut seamless steel pipe needs to be manually transferred to the grinding mechanism for end face grinding. When grinding the end face, the steel pipe to be ground needs to be clamped again and then the end face is ground again.

[0004] This method involves a rather cumbersome operation. The cutting precision is low when the cutting mechanism moves downward. If the seamless steel pipe is not positioned steadily, it will seriously affect the cutting accuracy and increase the workload of subsequent grinding. Moreover, the re-clamping and repositioning method during the grinding of the seamless steel pipe will significantly increase the workload and make it impossible to achieve rapid cutting and grinding of the seamless steel pipe.

[0005] Therefore, there is a need to provide a seamless steel pipe cutting and grinding production line to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a seamless steel pipe cutting and grinding production line to solve the problems mentioned in the background.

[0026] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0027] 1. In this invention, by cooperating with the ranging component and the control and display module, the spacing adjustment component can be moved so that the distance between the cutting position and the spacing adjustment component is the desired cutting length of the steel pipe. This can meet the cutting requirements of different lengths of the steel pipe to be cut. By using the first clamping component, one end of the steel pipe to be cut can be pressed down and positioned. By using the second clamping component, the other end of the steel pipe to be cut can be clamped at two points. This can achieve efficient and stable clamping of the steel pipe to be cut, improve the stability of the steel pipe to be cut during cutting, and avoid the problem of insufficient cutting accuracy caused by the instability of the steel pipe to be cut during the cutting process. By using the laser cutting component, the steel pipe to be cut can be cut quickly, improving the cutting efficiency of the steel pipe to be cut.

[0028] 2. In this invention, the switching component drives the second clamping component to rotate clockwise, causing the steel pipe to be ground to rotate, so that the steel pipe to be ground corresponds to the grinding component. The grinding component can grind both ends of the steel pipe to be ground. After grinding, the switching component, in cooperation with the second clamping component, drives the ground steel pipe to rotate clockwise. When the steel pipe to be ground rotates to the appropriate position, the clamping of the steel pipe to be ground is released. The steel pipe to be ground will move down under its own gravity and fall to the outside through the discharge port, realizing the cutting of the steel pipe to be ground and the grinding of the steel pipe to be cut. It can realize the switching of workstations, that is, the orderly cyclic switching of the cutting workstation at the top - the grinding workstation on the right - the discharge workstation on the left - the cutting workstation at the top. This avoids the need for workers to manually transfer the steel pipe to be ground to the grinding machine for grinding after the workpiece is cut, reducing the workload of workers, saving processing time, and improving the processing efficiency of the workpiece.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0051] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0052] In one embodiment of the present invention, see Figures 1-2 A seamless steel pipe cutting and grinding production line includes an outer shell 1. A protective cover 101 is provided at one top end of the outer shell 1. A discharge port 103 is provided on one side of the bottom of the outer shell 1. An opening 105 is provided at the top of the outer shell 1. A first clamping assembly 2 for clamping a steel pipe 10 to be cut is provided between the outer side of the protective cover 101 and the outer shell 1. A laser cutting assembly 3 for cutting the steel pipe 10 is provided between the protective cover 101 and the top of the outer shell 1. A second clamping assembly 4 is movably provided inside the outer shell 1. The second clamping assembly 4 is used to clamp the end of the steel pipe 10 to be cut away from the first clamping assembly 2 or to clamp both ends of the steel pipe 11 to be ground. The outer shell 1 has side walls... A switching component 6 connected to the second clamping component 4 is provided. A spacing adjustment component 5 is movably provided inside the housing 1 at the end of the housing 1 away from the first clamping component 2. A grinding component 7 is provided on the housing 1 and is movably engaged with the spacing adjustment component 5. The grinding component 7 is located on the side of the housing 1 away from the discharge port 103. The grinding component 7 is used to grind both ends of the steel pipe 11 to be ground. A distance measuring component 8 is provided between the protective cover 101 and the spacing adjustment component 5. The distance measuring component 8 is used to detect the distance between the spacing adjustment component 5 and the protective cover 101. A control and display module 9 electrically connected to the electrical equipment on the production line is provided on the outer wall of the housing 1.

[0053] In this embodiment, the distance measuring component 8 and the control and display module 9 work together to control the movement of the spacing adjustment component 5, so that the distance between the cutting position and the spacing adjustment component 5 is the desired cutting length of the steel pipe. The first clamping component 2 can press down and position one end of the steel pipe 10 to be cut, and the second clamping component 4 can clamp the other end of the steel pipe 10 at two points. The laser cutting component 3 can quickly cut the steel pipe 10. After the steel pipe 10 is cut, the steel pipe 11 to be ground is obtained. The switching component 6 drives the second clamping component 4 to rotate clockwise to move the steel pipe 11 to be ground. 1. Rotation aligns the steel pipe 11 to be ground with the grinding component 7. The grinding component 7 can grind both ends of the steel pipe 11. After grinding, the switching component 6, in cooperation with the second clamping component 4, drives the ground steel pipe 11 to rotate clockwise. When the steel pipe 11 rotates to the appropriate position, the clamping of the steel pipe 11 is released. The steel pipe 11 will move down under its own weight and fall to the outside through the discharge port 103. This achieves the cutting of the steel pipe 11 and the grinding of the steel pipe 10 to be cut, enabling continuous cutting and grinding and avoiding the problem of operating cutting and grinding on two separate machines.

[0054] The outer shell 1 has a discharge plate 102 at its bottom corresponding to the discharge port 103. The discharge plate 102 facilitates the directional discharge of the steel pipe 11 to be ground after grinding. The outer shell 1 has several symmetrical support legs 104 at its bottom. The support legs 104 can provide stable support for the outer shell 1 and improve the stability of cutting and grinding. The opening 105 has a protrusion at one end near the grinding component 7 to facilitate the rotation of the cut pipe and avoid interference between the pipe and the outer shell 1 during the rotation process. The control and display module 9 includes a control module, a display module and a processing module, all of which are installed using existing equipment.

[0055] In one embodiment of the present invention, see Figures 1-3 The first clamping assembly 2 includes an extended bottom plate 206 disposed on the outer wall of the outer shell 1 near the protective cover 101 and an extended top plate 205 disposed on the top of the protective cover 101. A first support arc plate 201 for supporting the bottom of the steel pipe 10 to be cut is installed on the extended bottom plate 206. A positioning pressure plate 202 that movably abuts against the top of the steel pipe 10 to be cut is movably disposed between the extended top plate 205 and the extended bottom plate 206. A plurality of first guide rods 204 that slide in cooperation with the positioning pressure plate 202 are disposed between the extended top plate 205 and the extended bottom plate 206. A first electric cylinder 203 is connected between the positioning pressure plate 202 and the extended top plate 205.

[0056] In this embodiment, the steel pipe 10 to be cut is placed on the first support arc plate 201. The first electric cylinder 203 extends downward and pushes the positioning plate 202 downward. The positioning plate 202 performs multi-point clamping operation on the steel pipe 10 to be cut by cooperating with the first support arc plate 201, which can stably position one end of the steel pipe 10 to be cut, thus facilitating the stability of the cutting of the steel pipe 10.

[0057] The positioning plate 202 is provided with a V-shaped groove or an arc groove on the side near the first support arc plate 201. The positioning effect of the steel pipe 10 to be cut can be improved by the V-shaped groove or arc groove.

[0058] In one embodiment of the present invention, see Figures 1-3 The laser cutting assembly 3 includes a side plate 301 disposed on the top of the protective cover 101, a second electric cylinder 302 mounted on the side plate 301, and a sliding seat 303 slidably disposed on the top of the protective cover 101 and connected to the outer end of the second electric cylinder 302, the sliding seat 303 being close to the laser cutter 304 on the top of the outer shell 1.

[0059] In this embodiment, initially, the laser cutter 304 is located on one side of the steel pipe 10 to be cut, and the second electric cylinder 302 is at its original length. When it is necessary to cut the steel pipe 10, the laser cutter 304 is turned on, the second electric cylinder 302 extends and pushes the sliding seat 303 to slide, and the sliding seat 303 drives the laser cutter 304 to move synchronously. The laser cutter 304 realizes the cutting operation of the steel pipe 10 by moving from one side of the steel pipe 10 to the other side of the steel pipe 10 to be cut.

[0060] In one embodiment of the present invention, see Figures 1-9 The second clamping assembly 4 includes a first rotating rod 401 rotatably disposed inside the housing 1. A first guide groove 4011 is provided at the end of the first rotating rod 401 away from the laser cutting assembly 3. A first mounting frame 402 is mounted at the end of the first rotating rod 401 near the laser cutting assembly 3. A second mounting frame 409 is movably sleeved on the first rotating rod 401 and slides in cooperation with the first guide groove 4011. Several sets of slots 410 are circumferentially distributed on the outer walls of the first mounting frame 402 and the second mounting frame 409. Rotary seats 405 corresponding to the slots 410 are provided on the inner walls of the first mounting frame 402 and the second mounting frame 409. A rotating seat 405 rotatably connected to the rotating seat 405 passes through the slot. The side clamping plate 404 of 410 has one end located at the end of the second supporting arc plate 403 away from the first mounting frame 402 or the second mounting frame 409, and the other end located inside the first mounting frame 402 or the second mounting frame 409. A plurality of connecting plates 407 are circumferentially distributed inside the first mounting frame 402 or the second mounting frame 409. The two ends of the connecting plates 407 are respectively movably connected to the end of the corresponding side clamping plate 404 located inside the first mounting frame 402 or the second mounting frame 409 through hinge rods 406. The inner wall of the first mounting frame 402 or the inner wall of the second mounting frame 409 is connected to the connecting plates 407 through a third electric cylinder 408.

[0061] The switching assembly 6 includes a rotating disk 605 rotatably mounted on the side wall of the outer casing 1. The rotating disk 605 is connected to the end of the first rotating rod 401 that passes through the side wall of the outer casing 1. A rotating groove 606 is provided on the side away from the outer casing 1. The rotating groove 606 includes several circumferentially distributed circular grooves. A mounting bracket 601 is installed on the side wall of the outer casing 1. A cutting motor 602 is installed on the mounting bracket 601. The output shaft of the cutting motor 602 is connected to a rotating residual wheel 603 that is movably engaged with the rotating groove 606. The rotating residual wheel 603 is slidably engaged with the uppermost circular groove. One end of the rotating residual wheel 603 is connected to an abutment rod 607. Several abutment rods 607 are circumferentially distributed on the outer end of the rotating disk 605.

[0062] In this embodiment, in the initial state, the included angle between the two side clamps 404 corresponding to the opening 105 is at its maximum value, the included angle between the two side clamps 404 corresponding to the discharge port 103 is at its maximum value, and the included angle between the two side clamps 404 corresponding to the grinding assembly 7 is at its minimum value. The rotating residual wheel 603 cooperates with the rotating groove 606. At this time, the angle of the rotating disk 605 is fixed.

[0063] According to the distance measuring component 8 and the required cutting length, the position of the spacing adjustment component 5 is adjusted, the steel pipe 10 to be cut is placed on the first support arc plate 201, and the steel pipe 10 to be cut is pushed towards the spacing adjustment component 5, so that the end of the steel pipe 10 to be cut away from the laser cutting component 3 abuts against the spacing adjustment component 5. The third electric cylinder 408, which is located on the first mounting frame 402 and the second mounting frame 409 respectively and corresponds to the opening 105, is controlled to extend. The third electric cylinder 408 drives the connecting plate 407 to move synchronously, the hinge rod 406 and the side clamping plate 404 are connected, and the side clamping plate 404 and the rotating seat 405 rotate in cooperation, so that the two corresponding side clamping plates 404 rotate towards the middle, so that the included angle between the two side clamping plates 404 becomes smaller. The two side clamping plates 404 clamp the steel pipe 10 to be cut by cooperating with the second support arc plate 403, so as to facilitate the stable cutting of the steel pipe 10.

[0064] After the steel pipe 10 is cut, the cutting motor 602 drives the rotating residual wheel 603 to rotate clockwise. The rotating residual wheel 603 drives the lever 604 to rotate synchronously. During the upward rotation of the lever 604, the lever 604 does not contact the abutment rod 607 on the left. When the lever 604 rotates to the highest point, the lever 604 contacts the abutment rod 607 located at the highest point. At this time, the rotating residual wheel 603 does not engage with the uppermost circular groove. During the downward rotation of the lever 604, the lever 604 drives the rotating disk 605 to rotate clockwise by contacting the abutment rod 607 and by rotating the rotating disk 605 in conjunction with the side wall of the outer casing 1. When the lever 604 rotates downward to a certain angle, the circular groove originally located on the left will rotate upward. The rotating wheel 603 will re-slide and engage with the circular groove. As the rotating wheel 603 continues to rotate, it drives the rotating disk 605 to continue rotating upward through the sliding engagement with the circular groove. When the lever 604 is not in contact with the connecting plate 407, the abutment lever 607, which was originally located on the left, rotates to the top, enabling the intermittent rotation of the rotating disk 605. This allows for the switching of workstations, namely, an orderly cycle switching between the cutting station at the top, the grinding station on the right, the unloading station on the left, and the cutting station at the top. This avoids the need for workers to manually transfer the workpiece to the grinding machine for grinding after the workpiece is cut, reducing the workload of workers, saving processing time, and improving the processing efficiency of the workpiece.

[0065] Specifically, when the 10 steel pipes to be cut are in the cutting position, the steel pipes to be cut are clamped by the cooperation of the two corresponding side clamps 404 and the second support arc plate 403, so that the laser cutting assembly 3 can cut the steel pipes to be cut. After the steel pipes to be cut are cut, the cut-off pipe is the steel pipe to be ground 11. The mounting frame 601 drives the cutting motor 602 to rotate clockwise, which can realize the clockwise rotation of the rotating disk 605. The rotating disk 605 drives the steel pipe to be ground 11 to rotate clockwise synchronously by connecting it to the first rotating rod 401 and the first rotating rod 401 to the first mounting frame 402 and the second mounting frame 409, so that the steel pipe to be ground 11 rotates to the grinding assembly 7. Through the grinding assembly 7, both ends of the steel pipe to be ground 11 can be ground. While grinding both ends of the grinding assembly 7, the laser cutting assembly 3 can grind the steel pipe to be ground 11 that is back in the cutting position. The steel pipe 10 is cut. After the steel pipe 10 is cut and the two ends of the grinding component 7 are ground, the mounting frame 601 drives the cutting motor 602 to continue to rotate clockwise, so that the newly cut steel pipe 11 to be ground rotates to the grinding component 7. The steel pipe 11 to be ground, which was originally located at the grinding component 7, rotates to the top of the discharge port 103. The third electric cylinder 408 corresponding to the discharge port 103 is controlled to retract. The third electric cylinder 408 drives the connecting plate 407 to move synchronously. The connecting plate 407 drives the two side clamps 404 corresponding to the discharge port 103 to rotate outward through the connection with the hinge rod 406 and the rotation cooperation between the rotating seat 405 and the side clamp 404. This makes the included angle between the two side clamps 404 larger, releasing the clamping treatment of the corresponding steel pipe 11 to be ground. The steel pipe 11 to be ground will pass through the discharge port 103 under its own gravity, realizing the export of the cut and ground pipe.

[0066] The slot 410 is provided in three sets, the number of abutting rods 607 is the same as the number of slots 410, the circular groove of the rotating groove 606 corresponds to the abutting rod 607, which facilitates the stability of workstation switching, and the first mounting frame 402 and the second mounting frame 409 are both set as regular hexagonal frames.

[0067] In one embodiment of the invention, see Figures 1-7The spacing adjustment component 5 includes a movable frame 501 movably disposed inside the housing 1 at one end away from the laser cutting component 3. The end of the movable frame 501 near the second mounting frame 409 is connected to a connecting ring frame 506 that rotatably engages with the second mounting frame 409. The side of the movable frame 501 near the laser cutting component 3 is provided with an abutment plate 503 corresponding to the steel pipe 10 to be cut. The housing 1 is provided with a second guide rod 502 that slidably engages with the movable frame 501. The housing 1 is provided with a screw 505 that is threadedly connected to the movable frame 501. The screw 505 is connected to a movable motor 504 installed on the side wall of the housing 1.

[0068] The ranging component 8 includes a reflector 801 disposed on the side of the protective cover 101 near the moving frame 501 and a laser rangefinder 802 disposed on the moving frame 501, the laser rangefinder 802 corresponding to the reflector 801.

[0069] In this embodiment, since the position of the reflector 801 is fixed and the distance between the reflector 801 and the laser cutting assembly 3 is fixed, when it is necessary to cut the pipe to different lengths, it is only necessary to adjust the distance between the laser rangefinder 802 and the reflector 801.

[0070] Specifically, when the cutting length of the pipe needs to be adjusted, the moving motor 504 drives the screw 505 to rotate. The screw 505 moves the position of the moving frame 501 by means of a threaded connection with the moving frame 501 and a sliding engagement between the moving frame 501 and the second guide rod 502. The moving frame 501 drives the laser rangefinder 802 to move synchronously. Based on the cooperation of the laser rangefinder 802 and the reflector 801, the distance between the moving frame 501 and the cutting position can be monitored in real time, thereby meeting the cutting requirements of different pipe lengths and improving the applicability of the device.

[0071] The abutment plate 503 can abut the end of the steel pipe 10 to be cut away from the first clamping component 2. The rotating connection between the connecting ring frame 506 and the second mounting frame 409 allows the moving frame 501 to move synchronously with the second mounting frame 409. This ensures that there is a gap between the second mounting frame 409 and the end of the steel pipe 10 to be cut away from the laser cutting component 3, and allows for stable clamping of the cut steel pipe 11 to be ground, facilitating subsequent stable grinding operations.

[0072] In one embodiment of the present invention, see Figures 1-8The grinding assembly 7 includes a third rotating rod 702 rotatably disposed inside the housing 1. The third rotating rod 702 has a second guide groove 7021. One end of the third rotating rod 702 is connected to a grinding motor 701 mounted on the side wall of the housing 1. A fixing plate 703 is mounted inside the housing 1 near the laser cutting assembly 3. A first transmission wheel 704, rotatably engaging with the fixing plate 703, is connected to the third rotating rod 702. A first transmission belt 705 is rotatably disposed on the fixing plate 703. A second transmission wheel 706 is connected between the first transmission wheel 704 and the first transmission belt 705. A first grinding disc 707, connected to a first transmission belt 705, is rotatably mounted on the side of the fixed plate 703 near the movable frame 501. A third transmission wheel 708, which is slidably fitted onto the third rotating rod 702 and is in sliding cooperation with the second guide groove 7021, is rotatably mounted on the movable frame 501. A second transmission belt 709 connects the third transmission wheel 708 and the fourth transmission wheel 710. A second grinding disc 711, connected to the fourth transmission wheel 710, is rotatably mounted on the side of the movable frame 501 near the fixed plate 703. The second grinding disc 711 corresponds to the first grinding disc 707.

[0073] In this embodiment, the side of the abutment plate 503 near the laser cutting component 3 and the side of the second grinding disc 711 near the laser cutting component 3 are on the same vertical plane. The side of the first grinding disc 707 near the second grinding disc 711 and the cutting surface of the steel pipe 10 to be cut are on the same vertical plane. The moving frame 501 can drive the second grinding disc 711 to move synchronously by rotating with the third transmission wheel 708 and sliding with the third transmission wheel 708 and the second guide groove 7021, thereby performing end face grinding treatment on the pipe after cutting to different lengths.

[0074] Specifically, the grinding motor 701 drives the third rotating rod 702 to rotate, and the third rotating rod 702 drives the first transmission wheel 704 to rotate. The first transmission wheel 704 drives the first grinding disc 707 to rotate through connection with the second transmission wheel 706 and the first transmission belt 705 and the first grinding disc 707. At the same time, the third rotating rod 702 drives the second grinding disc 711 to rotate synchronously through sliding engagement of the third transmission wheel 708 and the second guide groove 7021, connection of the second transmission belt 709 and the third transmission wheel 708, and connection of the fourth transmission wheel 710 and the second grinding disc 711. The first grinding disc 707 can grind the two ends of the steel pipe 11 to be ground corresponding to the grinding assembly 7 by cooperating with the second grinding disc 711, so as to realize the rapid grinding operation of the steel pipe 11 to be ground.

[0075] The first grinding disc 707 has the same size as the second grinding disc 711, the first transmission wheel 704 has the same size as the third transmission wheel 708, and the first transmission belt 705 has the same size as the fourth transmission wheel 710, which can synchronize the grinding efficiency of the end face of the steel pipe 11 to be ground.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
