Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, in particular to a stainless steel pipe laser cutting device. Background Art

[0002] Stainless steel pipe is a hollow, long, round steel strip, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, it is lighter in weight when the bending and torsional strength are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. In order to meet application requirements, cutting work will be performed during the production and processing of stainless steel pipes.

[0003] A patent application with publication number CN119057269A discloses a stainless steel pipe laser cutting machine, which includes a base plate and two fixing components respectively arranged on both sides of the upper end of the base plate. The fixing components include a first circular ring, which is fixed to the base plate, and a second circular ring rotatably arranged in the middle of the first circular ring. The cutting machine clamps the steel pipe from the outside by driving a roller, and at the same time drives a cylindrical bar to fix the steel pipe from the inside of the steel pipe. There is no need to adjust the extrusion force of the clamping device on the steel pipe according to the thickness of the steel pipe. It is suitable for steel pipes of various thicknesses and prevents the steel pipe from being squeezed and deformed.

[0004] The above scheme still has some problems in actual application. When using the above-mentioned cutting machine to cut stainless steel pipes, due to the poor thermal conductivity of stainless steel, heat is easily concentrated during cutting, which will cause slag on the cut surface of the stainless steel pipe. In order to meet subsequent usage requirements, the stainless steel pipe needs to be cut into several small sections, which makes the cutting work take a long time. If the cut surface of the stainless steel pipe is processed after the cutting work is completed, these slags will gradually cool and solidify as the temperature drops, forming a solid connection with the stainless steel surface, and ultimately increasing the difficulty of processing. In addition, when grinding the cut surface, not only the small section of stainless steel pipe after cutting needs to be ground, but also the stainless steel pipe body during cutting needs to be ground. This work of grinding two cut surfaces at the same time will greatly increase the difficulty of the work.

[0005] To this end, the present invention provides a stainless steel tube laser cutting device. Summary of the Invention

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Example 1: Figures 1 to 12 As shown, a stainless steel tube laser cutting device according to an embodiment of the present invention includes a base frame 1, a lifting structure 3 is provided on one side of the upper surface of the base frame 1, the lifting structure 3 includes a lifting plate 32, the lifting plate 32 is connected to the surface of the base frame 1 by sliding up and down, a cutting structure 4 is provided at one end of the lifting plate 32, a conveying structure 2 is provided on the other side of the upper surface of the base frame 1, a grinding structure 5 is provided between the conveying structure 2 and the lifting structure 3; the cutting structure 4 includes a cutting module 41, the cutting module 41 is provided on the surface of the lifting plate 32, and a cutting head 42 is provided at one end of the cutting module 41; the grinding structure 5 includes: a transfer roller 505, a transfer roller 505 Located on the surface of the lifting plate 32; the abutment block 506, the abutment block 506 is located at one end of the base frame 1; the adjustment plate 502, the adjustment plate 502 is located on the surface of the base frame 1, and the surface of the adjustment plate 502 is provided with a slide rail 509; the grinding frame 522, the two grinding frames 522 are slidably connected to the inside of the slide rail 509, and the inside of the grinding frame 522 is provided with a grinding roller 521; the conveying structure 2 includes: an adjustment frame 25, the adjustment frame 25 is located on the upper surface of the base frame 1; the connecting plate 27, the connecting plate 27 is rotatably connected to the surface of the adjustment frame 25; the clamping bar 28, a plurality of clamping bars 28 are slidably connected to the surface of the connecting plate 27.

[0023] Specifically, a stainless steel tube laser cutting device of the present invention is mainly used for cutting a stainless steel tube 6. When in use, a longer tube 6 is first passed through the hole on the surface of the connecting plate 27 and moved toward the abutment block 506. When the portion of the tube 6 to be cut moves to the lower end of the cutting head 42, the clamping bar 28 is started, and the clamping bar 28 will slide on the surface of the connecting plate 27 to clamp the tube 6. Then, the lifting plate 32 is started, and the lifting plate 32 will move downward with the cutting module 41. When it moves to a position where it can be cut, the cutting module 41 is started. Block 41, the power supply inside the cutting module 41 will provide high voltage, and generate an arc between the electrode and the pipe 6 through the cutting head 42. The arc has an extremely high temperature, which is enough to quickly melt the local metal of the pipe 6, and at this time, the connecting plate 27 is started, and the connecting plate 27 will drive the pipe 6 to rotate, thereby achieving complete cutting of the pipe 6. After the shorter pipe 6 is cut off from the surface of the longer pipe 6, since the upper surface of the base frame 1 is provided with a plurality of gaskets, the shorter pipe 6 and the longer pipe 6 are at the same horizontal line at this time, and then the transfer roller 505 is started, and the transfer roller 50 5 will contact the surface of the shorter tube 6 and drive the shorter tube 6 to move toward the abutment block 506 and finally abut against the abutment block 506. At this time, the grinding frame 522 is started and moves upward along the inner wall of the slide rail 509. When it moves to the first corner of the slide rail 509, the two grinding frames 522 will move away from each other, thereby spreading out. When it moves to the second corner of the slide rail 509, the grinding frame 522 will move vertically, thereby grinding the cut surfaces of the shorter tube 6 and the longer tube 6 in the process of movement. The grinding is carried out, and since one end of the shorter pipe 6 is in contact with the abutment block 506, the grinding of the shorter pipe 6 can also be carried out smoothly at this time. By setting the grinding structure 5, after the shorter pipe 6 is cut off from the surface of the longer pipe 6, the transfer roller 505 will drive the shorter pipe 6 to move, which can not only ensure the limitation of the shorter pipe 6 for subsequent grinding processing, but also ensure that the two pipes 6 will not affect each other during the grinding process. After the shorter pipe 6 is moved, the grinding frame 522 can be started for grinding, thereby realizing synchronous and rapid grinding of the pipe 6 after cutting.

[0024] like Figures 1 to 12As shown, the lifting structure 3 also includes: a sliding rod 31, the sliding rod 31 is arranged at the upper end of the base frame 1, and the lifting plate 32 slides on the surface of the sliding rod 31; a screw 33, the screw 33 is rotatably connected to one side of the sliding rod 31, and the lifting plate 32 is threadedly connected to the screw 33; a limit frame 34, the limit frame 34 is arranged at the lower end of the lifting plate 32, and a first abutment roller 35 and a second abutment roller 36 are provided inside the limit frame 34; the grinding structure 5 includes: a fixed frame 501, the fixed frame 501 is arranged inside the base frame 1; a lifting frame 511, the lifting frame 511 is slidably connected to the inside of the fixed frame 501; a transverse rod 512, the transverse rod 512 is provided at the grinding One end of the frame 522, and the transverse rod 512 slides inside the lifting frame 511, and the transverse rod 512 slides on the inner wall of the slide rail 509; the fixed tooth plate 514, the fixed tooth plate 514 is arranged at one end of the lifting frame 511; the driving gear 515, the driving gear 515 is rotatably connected to the inside of the base frame 1, and the driving gear 515 is engaged with the fixed tooth plate 514; the conveying structure 2 also includes: a rotating plate 26, the rotating plate 26 is arranged on one side of the connecting plate 27; the motor 23, the motor 23 is arranged inside the base frame 1; the chain 24, one end of the chain 24 is sleeved on the surface of the motor 23, and the other end of the chain 24 is sleeved on the surface of the rotating plate 26.

[0025] Specifically, when the pipe 6 moves to the position to be cut, the screw rod 33 is started to rotate. Since the screw rod 33 is threadedly connected to the lifting plate 32, and the lifting plate 32 slides on the surface of the sliding rod 31, the lifting plate 32 will move downward at this time, thereby driving the cutting module 41 to move together. When it moves to the position where it can be cut, the first abutting roller 35 and the second abutting roller 36 inside the limit frame 34 will also contact the surface of the pipe 6, while playing a limiting effect, it can also ensure the rotation of the pipe 6 when cutting. Then, during the cutting process, the motor 23 is started, and the motor 23 will The chain 24 drives the connecting plate 27 to rotate, thereby realizing complete cutting of the pipe 6. When the shorter pipe 6 is cut and abuts against the abutment block 506, the driving gear 515 is started. The driving gear 515 will engage with the fixed tooth plate 514 during the rotation process, thereby causing the lifting frame 511 connected to the fixed tooth plate 514 to move upward. Since the transverse rod 512 connected to the grinding frame 522 slides inside the lifting frame 511, the grinding frame 522 will also move appropriately along the inner wall of the slide rail 509 at this time, and finally complete the grinding.

[0026] like Figures 1 to 6 As shown, a telescopic spring 37 is provided at the upper end of the second abutting roller 36, a connecting arm 38 is provided at the upper end of the first abutting roller 35, and the connecting arm 38 is rotatably connected inside the limit frame 34, and an adjusting spring 39 is provided at the rotating portion of the connecting arm 38 and the limit frame 34.

[0027] Specifically, by setting the telescopic spring 37 and the adjusting spring 39, when the first abutting roller 35 and the second abutting roller 36 press the tube 6, the telescopic spring 37 and the adjusting spring 39 will adaptively adjust the pressing force. While ensuring that the tube 6 is limited, it can also cope with tubes 6 of different sizes.

[0028] like Figure 12 As shown, a momentary switch 520 is provided on one side of each of the two grinding frames 522 , and the two momentary switches 520 are in contact with each other in an initial state.

[0029] Specifically, since the two grinding frames 522 are located at the lower end of the slide rail 509 in the initial state, the two momentary switches 520 are in contact with each other, the contacts inside the momentary switches 520 are disconnected, and the circuit is cut off, so that the grinding roller 521 will not rotate. When the two grinding frames 522 move to a point where they are no longer in contact, the contacts inside the momentary switches 520 are closed, and the circuit is connected, so that the grinding roller 521 rotates. This design can ensure the precise start-up of the grinding roller 521.

[0030] like Figures 1 to 4 As shown, a feeding frame 21 is provided at one end of the upper end of the base frame 1 close to the adjustment frame 25 , and a plurality of balls 22 are provided inside the feeding frame 21 .

[0031] Specifically, by setting up a feeding frame 21, when conveying the pipe 6, the pipe 6 is first passed through the inside of the feeding frame 21. Since a number of balls 22 are provided inside the feeding frame 21, the pipe 6 can be wrapped, so that when the pipe 6 enters the inside of the adjusting frame 25, it does not contact the inner wall of the adjusting frame 25, thereby reducing friction damage on the surface of the pipe 6.

[0032] like Figures 1 to 9 As shown, a plurality of buckles 510 are provided on the surface of the slide rail 509 , and the buckles 510 are engaged with the polishing frame 522 .

[0033] Specifically, by providing the buckle 510 , when the grinding frame 522 is at the initial position and the cutting completion position, the grinding frame 522 will be engaged with the buckle 510 , thereby ensuring the stability of the grinding frame 522 inside the slide rail 509 .

[0034] Example 2: Figures 1 to 8 As shown, compared with Example 1, another implementation of the present invention is: a limit block 504 is provided at the upper end of the base frame 1.

[0035] Specifically, by providing the limiting block 504 , after the shorter pipe 6 is cut, the limiting block 504 can limit the end of the shorter pipe 6 , thereby allowing the grinding work to proceed smoothly.

[0036] like Figures 1 to 11 As shown, the limit block 504 is rotatably connected to the upper surface of the base frame 1 , and a drop groove 12 is provided at one end of the upper surface of the base frame 1 close to the limit block 504 , and a collection frame 518 is provided at the lower end of the drop groove 12 .

[0037] Specifically, by setting the drop groove 12, after the shorter pipe 6 is polished, the limit block 504 is started to rotate. Since the limit block 504 is in contact with the end of the pipe 6, the pressing of the limit block 504 at this time can transfer the pipe 6 through the drop groove 12 to the inside of the collection frame 518 for collection.

[0038] like Figures 1 to 11 As shown, a fixing plate 513 is provided on one side of the lifting frame 511, and a plurality of tooth blocks 516 are provided on the surface of the fixing plate 513. A connecting spring 517 is provided between the tooth block 516 and the fixing plate 513. A fixing gear 508 is provided at one end of the limit block 504. The fixing gear 508 is rotatably connected to the surface of the base frame 1. An auxiliary gear 503 is provided on one side of the fixing gear 508, and both the fixing gear 508 and the tooth block 516 are engaged with the auxiliary gear 503. A coil spring 507 is provided at one end of the fixing gear 508.

[0039] Specifically, by setting the auxiliary gear 503, after the shorter pipe 6 is polished, the lifting frame 511 will move downward to reset. The tooth block 516 located on the surface of the fixed plate 513 at one end of the lifting frame 511 will engage with the fixed gear 508 at one end of the limit block 504 through the auxiliary gear 503 during the reset process, thereby driving the fixed gear 508 to rotate. During the rotation process, the limit block 504 connected to the fixed gear 508 will press and collect the shorter pipe 6 after polishing, and after the transfer of the pipe 6 is completed, the coil spring 507 at one end of the fixed gear 508 can also drive the limit block 504 to reset, thereby facilitating subsequent transfer work, and the tooth block 516 on the surface of the fixed plate 513 is a unidirectional rotating tooth block 516, so that the auxiliary gear 503 will not be driven during the rising process of the lifting frame 511.

[0040] like Figure 11 As shown, a plurality of placement slots 519 are provided on the surface of the collection frame 518 .

[0041] Specifically, by opening a plurality of placement grooves 519 on the surface of the collection frame 518, when the polished pipe 6 moves to the inside of the collection frame 518, it will contact the inner wall of the placement groove 519, which will not only have a sorting effect but also will not affect the stacking of the pipe 6.

[0042] Working principle: When in use, first pass a longer pipe 6 through the hole on the surface of the connecting plate 27 and move it toward the abutment block 506. When the part of the pipe 6 to be cut moves to the lower end of the cutting head 42, start the clamping bar 28. The clamping bar 28 will slide on the surface of the connecting plate 27 to clamp the pipe 6. At this time, start the screw 33 to rotate. Since the screw 33 is threadedly connected to the lifting plate 32 and the lifting plate 32 slides on the surface of the sliding rod 31, the lifting plate 32 will move downward at this time, thereby driving the cutting module 41 to move together. When it moves to the part that can be cut, the inner part of the limit frame 34 The first abutting roller 35 and the second abutting roller 36 will also contact the surface of the pipe 6, which will not only play a limiting role, but also ensure the rotation of the pipe 6 during cutting. At this time, the cutting module 41 is started, and the power supply inside the cutting module 41 will provide high voltage, and an arc will be generated between the electrode and the pipe 6 through the cutting head 42. This arc has an extremely high temperature, which is enough to quickly melt the local metal of the pipe 6. At this time, the motor 23 is started, and the motor 23 will drive the connecting plate 27 to rotate through the chain 24. The connecting plate 27 will drive the pipe 6 to rotate, thereby realizing the complete cutting of the pipe 6. When the shorter pipe 6 is cut from the longer pipe 6, the shorter pipe 6 can be cut off from the longer pipe 6. After the surface is cut, since the upper surface of the base frame 1 is provided with a plurality of gaskets, the shorter pipe 6 and the longer pipe 6 are at the same horizontal line at this time, and then the transfer roller 505 is started, the transfer roller 505 will contact the surface of the shorter pipe 6, and drive the shorter pipe 6 to move toward the abutment block 506, and finally abut against the abutment block 506, at this time, the driving gear 515 is started, and the driving gear 515 will mesh with the fixed tooth plate 514 during the rotation process, so that the lifting frame 511 connected to the fixed tooth plate 514 moves upward, and since the transverse rod 512 connected to the grinding frame 522 is in the lifting The lowering frame 511 slides internally, and the grinding frame 522 will also move upward along the inner wall of the slide rail 509. When moving to the first corner of the slide rail 509, the two grinding frames 522 will move away from each other, thereby expanding. When moving to the second corner of the slide rail 509, the grinding frame 522 will move vertically, thereby grinding the cut surfaces of both the shorter pipe 6 and the longer pipe 6 during the movement, and because one end of the shorter pipe 6 abuts against the abutment block 506, the grinding of the shorter pipe 6 will also proceed smoothly at this time, thereby realizing synchronous and rapid grinding of the pipe 6 after cutting.
