Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting, in particular to a laser cutting segmentation device for large-diameter thin-wall low-thermal expansion alloy pipe blanking. BACKGROUND

[0002] In the fields of high-end manufacturing such as aerospace, precision instruments, and energy equipment, large-diameter thin-wall low-thermal expansion alloy pipes have become the core materials of key structural components due to their extremely low thermal expansion coefficient, excellent high-temperature stability, and lightweight characteristics. The diameter of such pipes usually exceeds 300 mm, but the wall thickness is less than 5 mm. The alloy composition contains elements such as nickel, iron, and cobalt. During processing, deformation may occur due to stress concentration, which poses strict requirements on blanking precision. Traditional mechanical cutting methods have problems such as rapid tool wear, many cutting burrs, and large heat-affected zones, making it difficult to meet the precision requirements of thin-wall structures. Laser cutting, on the other hand, uses high-energy density beams for non-contact processing, allowing precise control of heat input and effectively reducing pipe deformation. The smooth cutting edge and dimensional accuracy of ±0.05 mm significantly improve the efficiency of subsequent welding and assembly processes. However, existing laser cutting devices have the following shortcomings when in use:

[0003] 1. The slag produced by laser cutting is mostly molten metal debris that solidifies at high temperatures. When attached to the inner wall of a thin-wall low-thermal expansion alloy pipe, it forms irregular protrusions or point-like impurities. For pipes that transport high-precision fluids, these slag can increase the flow resistance of the medium, even cause local vortexes, and result in pressure loss or unstable flow. At the same time, the slag attachment point is prone to accumulate pollutants, which may breed microorganisms or cause chemical corrosion over time, damaging the corrosion resistance of the alloy pipe and shortening the service life of the pipe.

[0004] 2. Due to the narrow space inside the large-diameter thin-wall pipe, the residual slag may be deformed during pipe welding and assembly, forming micro-cracks or stress concentration areas and reducing the structural strength of the alloy pipe. In addition, during non-destructive testing, the slag may interfere with the detection signal, leading to false positives or missed detections, and making it impossible to accurately assess the actual damage to the inner wall of the pipe, posing a safety hazard to high-end equipment. SUMMARY

[0005] In view of the problems in the prior art of damaging the smoothness of the inner wall, increasing fluid resistance, causing corrosion, shortening the service life, and increasing the difficulty of cleaning and detection, which may form cracks and pose safety hazards, a laser cutting segmentation device for large-diameter thin-wall low-thermal expansion alloy pipe blanking is proposed.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0043] Example 1, refer to Figures 1-7For the first embodiment of the present application, a laser cutting segmentation device for large-diameter thin-wall low-expansion alloy pipe blanking is provided, which comprises a workbench 1, a vertical plate 11 fixedly connected to the top of the workbench 1, an alloy pipe body 12 clamped on the vertical plate 11, a telescopic cylinder 13 slidingly connected to the vertical plate 11, a laser cutting head 14 fixedly connected to the output end of the telescopic cylinder 13, and a U-shaped frame 15 slidingly connected to the top of the workbench 1; and a material receiving unit installed on the workbench 1; the material receiving unit comprises a material receiving component, a material discharging component, and a locking component installed on the workbench 1, the material receiving component comprises a material receiving assembly 2 and a tensioning assembly 3 installed on the U-shaped frame 15, and an unfolding assembly 4 is installed on the tensioning assembly 3; the material receiving component receives the slag cut from the alloy pipe body 12, the material discharging component discharges the cut alloy pipe body 12 and the received slag, and the locking component is used for locking the material discharging component to assist the material discharging component in discharging; the material receiving assembly 2 comprises a material receiving box 21 rotatingly connected to the U-shaped frame 15, a material receiving hopper 22 fixedly connected to the top of the material receiving box 21, and a sealing plate 23 rotatingly connected to one end of the material receiving box 21, and two first spheres 24 are fixedly connected to the sealing plate 23 in a symmetrical manner.

[0044] Specifically, first, the alloy pipe body 12 is stably fixed through the clamping structure on the vertical plate 11 to ensure that the pipe material does not displace during cutting. Then, according to the cutting requirements, the U-shaped frame 15 is slid on the workbench 1 to the appropriate position, and the relative position of the material receiving assembly 2 and the alloy pipe body 12 is adjusted. In the cutting stage, the telescopic cylinder 13 slides along the vertical plate 11, driving the laser cutting head 14 to accurately move to the cutting starting point, and starting the laser cutting operation. At the same time, the material receiving assembly 2 on the U-shaped frame 15 enters the working state synchronously, the material receiving hopper 22 is aligned below the cutting position, and the slag generated by cutting falls into the material receiving hopper 22 under the action of gravity, and then is guided into the material receiving box 21. At this time, the sealing plate 23 at one end of the material receiving box 21 is in a closed state, effectively preventing the slag from leaking out during the receiving process. During the cutting process, the tensioning assembly 3 is adjusted according to the diameter of the alloy pipe body 12, the alloy pipe body 12 is clamped from the inside through the unfolding assembly 4, and the alloy pipe body 12 is prevented from tilting downward during the cutting process, causing uneven cutting. After cutting is completed, the material discharging component starts to work. The locking component works synchronously to fix the running path of the material discharging component, ensuring that the discharging process is stable and orderly. Then, the material receiving box 21 rotates to open the sealing plate 23, and the slag collected in the material receiving box 21 is discharged together with the cut alloy pipe body 12, realizing efficient separation of the slag and the pipe material, and reducing the adhesion of the slag to the inner wall of the pipe from the source.

[0045] Reference Figure 5The tensioning assembly 3 comprises a fixed rod 31 rotatably connected to the U-shaped frame 15, a driving motor 32 fixedly connected to the fixed rod 31, a groove formed in the fixed rod 31, a threaded rod 33 rotatably connected to the inner side of the groove, the output shaft of the driving motor 32 fixedly connected to the threaded rod 33, and a nut 34 threadedly connected to the threaded rod 33 and limitingly and slidably connected to the inner side of the groove.

[0046] Specifically, the driving motor 32 is started to drive the threaded rod 33 in the groove of the fixed rod 31 to rotate. Since the nut 34 is limitingly and slidably connected to the inner side of the groove, the rotation of the threaded rod 33 will cause the nut 34 to translate along the groove. When the nut 34 moves, the expansion assembly 4 is linked to expand to adapt to alloy pipe bodies 12 of different diameters.

[0047] Referring to Figure 5 and Figure 6 , the expansion assembly 4 comprises a disc 41 fixedly connected to the fixed rod 31, the receiving box 21 fixedly connected to the disc 41, a plurality of movable grooves arranged in an annular array on the disc 41, a telescopic rod 42 slidably connected to the inner side of the movable groove, a first spring 43 fixedly connected between the inner wall of the movable groove and the telescopic rod 42, a tensioning rope 44 fixedly connected to one end of the telescopic rod 42, the other end of the telescopic rod 42 rotatably connected to a second ball 45, and the second ball 45 rollingly connected to the inner wall of the alloy pipe body 12.

[0048] Specifically, the expansion assembly 4 is driven by the tensioning assembly 3 to work cooperatively. When the nut 34 translates along the groove of the fixed rod 31, the tensioning rope 44 connected to the nut 34 is pulled. The tensioning rope 44 drives the telescopic rod 42 to slide in the movable groove of the disc 41, and at this time, the first spring 43 between the inner wall of the movable groove and the telescopic rod 42 is deformed. When the nut 34 moves towards the driving motor 32, the tensioning rope 44 relaxes, the first spring 43 resets to push the telescopic rod 42 to extend outward, so that the second ball 45 is in close contact with the inner wall of the alloy pipe body 12; when the nut 34 moves reversely, the tensioning rope 44 tightens to pull the telescopic rod 42 to retract, so as to adapt to the pipe material of smaller diameter. Through such adjustment, the second ball 45 can always rollingly fit the inner wall of the alloy pipe body 12 of different diameters, which not only ensures the stable support of the pipe material, but also cooperates with the receiving assembly 2 to more accurately receive the cut slag, improves the adaptability of the device to different specifications of pipe materials, and can accurately extend into the pipe material of different diameters.

[0049] Referring to Figure 8, the unloading component includes a rotating assembly 5 installed on the workbench 1, a poking assembly 6 installed on the U-shaped frame 15, and a clamping assembly 7 installed on the workbench 1; the rotating assembly 5 includes a T-shaped groove formed in the workbench 1, a T-shaped block 51 slidably connected to the inner side of the T-shaped groove, a second spring 52 fixedly connected between the inner wall of the T-shaped groove and the T-shaped block 51, a connecting seat 53 fixedly connected to the top of the T-shaped block 51, a special-shaped rod 54 slidably connected to the connecting seat 53, a first connecting shaft 55 movably connected to the U-shaped frame 15, a rotating disc 56 fixedly connected to the first connecting shaft 55, and the special-shaped rod 54 movably connected to the rotating disc 56 at the end away from the connecting seat 53.

[0050] Specifically, when the U-shaped frame 15 slides on the top of the workbench 1, the rotating assembly 5 is driven to move by the first connecting shaft 55, the T-shaped block 51 slides on the inner side of the T-shaped groove, the second spring 52 is stretched, the rotating disc 56 is driven to rotate under the action of the special-shaped rod 54, the first connecting shaft 55 is driven to rotate, the receiving assembly 2 is driven to rotate, and the receiving assembly 2 is tilted to unload the cut alloy pipe body 12 and the dregs in the receiving box 21. When the T-shaped block 51 slides on the inner side of the T-shaped groove, the T-shaped block 51 is clamped by the clamping assembly 7, when the T-shaped block 51 is reset, the T-shaped block 51 is clamped by the clamping assembly 7, when the U-shaped frame 15 moves, the rotating disc 56 is reversely rotated and reset under the action of the special-shaped rod 54, and the receiving assembly 2 is rotated to a horizontal state.

[0051] Embodiment 2, refer to Figure 7 and Figure 9 , which is different from the first embodiment, the poking assembly 6 includes a fixing seat 61 rotatably connected to the U-shaped frame 15, a second connecting shaft 62 fixedly connected to the fixing seat 61, two sliding grooves symmetrically formed in the U-shaped frame 15, a sliding block 63 slidably connected to the inner side of the sliding groove, a third spring 64 fixedly connected between the inner wall of the sliding groove and the sliding block 63, the first connecting shaft 55 penetrating through one of the sliding blocks 63 and fixedly connected to the fixing seat 61, the second connecting shaft 62 rotatably connected to the other sliding block 63, a contact rod 65 fixedly connected to the fixing seat 61, a plurality of arc-shaped blocks 66 fixedly connected to the workbench 1, the contact rod 65 abutting against the arc-shaped blocks 66, and the fixed rod 31 penetratingly connected to the fixing seat 61.

[0052] Specifically, the fixed seat 61 is initially in a horizontal state, and the abutting rod 65 is in an inclined state. When the first connecting shaft 55 rotates, it drives the fixed seat 61 to rotate, and under the action of the second connecting shaft 62, the fixed seat 61 is inclined, so that the abutting rod 65 is vertically downward. When the U-shaped frame 15 moves, it drives the fixed seat 61 to move, so that the abutting rod 65 abuts against the arc-shaped block 66. Under the action of the arc-shaped block 66, the abutting rod 65 moves upward, so that the fixed seat 61 moves upward, and the sliding block 63 slides upward in the sliding groove, stretching the third spring 64. When the abutting rod 65 does not abut against the arc-shaped block 66, the third spring 64 resets, driving the sliding block 63 to slide downward in the sliding groove, driving the fixed seat 61 to move downward, and further driving the fixed seat 61 to vibrate up and down, driving the fixed rod 31 to vibrate up and down, and driving the material receiving assembly 2 to vibrate up and down, thereby shaking off the dregs in the material receiving box 21 and shaking down the cut alloy pipe body 12.

An inclined surface is also formed on the T-shaped block 51.

[0054] Specifically, when the T-shaped block 51 slides in the T-shaped groove and under the action of the inclined surface, the clamping rod 72 moves into the clamping groove 71, compressing the clamping spring 73. When the clamping groove 74 moves to the position of the clamping rod 72, the clamping spring 73 resets, moving the clamping rod 72 into the inner side of the clamping groove 74, and limiting the T-shaped block 51. When the U-shaped frame 15 moves and resets, the rotating disc 56 rotates under the action of the special-shaped rod 54, rotating the fixed seat 61 to reset to a horizontal state. When the U-shaped frame 15 continues to move, the clamping rod 72 is separated from the inner side of the clamping groove 74, releasing the limitation of the T-shaped block 51, so that the T-shaped block 51 can move to reset.

[0055] With reference to Figures 11-13 , the locking component comprises a locking assembly 8 mounted on the U-shaped frame 15, a transmission assembly 9 mounted on the locking assembly 8, and a steering assembly 10 mounted on the transmission assembly 9.

[0056] Specifically, initially, the locking rod 81 is inserted into the second locking groove 83, so that the second connecting shaft 62 cannot rotate, the fixed seat 61 is limited, and the material receiving assembly 2 remains horizontal. Under the action of the transmission assembly 9, the locking rod 81 is pulled out from the second locking groove 83 and then inserted into the first locking groove 82, so that the second connecting shaft 62 is limited again and cannot rotate at will. The remaining structure is the same as that of the first embodiment.

[0060] Specifically, initially the push rod 105 is located at the top of the vertical slot 101, when the rotating shaft 91 moves upward, the push rod 105 slides downward from the top of the vertical slot 101, passes through the second rubber wedge block 104, and slides to the bottom of the vertical slot 101, when the rotating shaft 91 moves downward, under the action of the second rubber wedge block 104, the push rod 105 smoothly enters the inside of the spiral slot 102, under the action of the spiral slot 102, the rotating shaft 91 rotates, until the push rod 105 moves to the top of the spiral slot 102, passes through the first rubber wedge block 103, and smoothly enters the inside of the vertical slot 101, so that the rotating shaft 91 can drive the rotating wedge block 96 to rotate, so that the inclined surface of the rotating wedge block 96 always faces the abutting rod 97, ensuring that the U-shaped frame 15 can always drive the abutting rod 97 to act on the rotating wedge block 96 when moving.

[0061] With reference to Figure 14 Further comprising a clamping assembly 16, the clamping assembly 16 comprises a circular ring 161 rotatably connected to the vertical plate 11, two electric push rods 162 are fixedly connected to the circular ring 161 in a symmetrical manner, and the output ends of the electric push rods 162 are fixedly connected with arc-shaped clamping plates 163.

[0062] Specifically, the electric push rod 162 is started to drive the two arc-shaped clamping plates 163 to move and clamp the alloy pipe body 12. The circular ring 161 can drive the electric push rod 162 to rotate, and in turn drive the alloy pipe body 12 to rotate, and in turn perform laser cutting on different surfaces of the alloy pipe body 12. The remaining structure is the same as that of the embodiment 2.

[0063] In combination with the above-mentioned embodiments 1-3, the working principle of the present application is as follows: first, the alloy pipe body 12 is fixed by the clamping assembly 16 on the vertical plate 11: the electric push rod 162 drives the arc-shaped clamping plate 163 to clamp the pipe, and the circular ring 161 can drive the pipe to rotate to adjust the cutting surface. The U-shaped frame 15 is slid to the appropriate position, so that the material receiving assembly 2 is aligned below the cutting point. The telescopic cylinder 13 drives the laser cutting head 14 to move for cutting, and the tensioning assembly 3 is started synchronously: the driving motor 32 drives the threaded rod 33 to rotate, so that the nut 34 slides along the groove of the fixed rod 31, and the tensioning rope 44 pulls the telescopic rod 42 of the unfolding assembly 4. The telescopic rod 42 slides in the movable groove of the disc 41, cooperates with the first spring 43 to adjust the telescopic amount, and makes the second ball 45 closely fit the inner wall of the pipe, which not only supports the pipe to prevent tilting, but also adapts to different pipe diameters. The slag generated by cutting falls into the material receiving hopper 22 and enters the material receiving box 21, the unloading part is started, the U-shaped frame 15 moves to drive the T-shaped block 51 of the rotating assembly 5 to slide in the T-shaped groove, the second spring 52 is stretched, the special-shaped rod 54 pushes the rotating disc 56 to rotate, so that the material receiving box 21 is inclined. The clamping rod 72 of the clamping assembly 7 is clamped into the clamping groove 74 of the T-shaped block 51 under the action of the clamping spring 73, and the unloading angle is fixed. At the same time, the toggle assembly 6 works: the U-shaped frame 15 moves to make the abutting rod 65 abut against the arc-shaped block 66, drives the fixed seat 61 to move up and down, the slider 63 compresses the third spring 64 and then resets, so that the material receiving assembly 2 vibrates to shake off the slag and the cut pipe. The locking part cooperates with the unloading: when the U-shaped frame 15 moves, the rotating wedge-shaped block 96 of the transmission assembly 9 contacts the abutting rod 97, drives the rotating shaft 91 to rise, and makes the locking rod 81 disengage from the second locking groove 83 through the toothed plate 92 and the gear 93. After unloading is completed, the U-shaped frame 15 is reset, and each assembly returns to the initial state under the action of the spring, preparing for the next cutting.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
