Description

Technical Field

[0001] This application relates to the technical field of metal processing equipment, and particularly relates to an H-beam and pipe cutting device. Background Art

[0002] In traditional metal cutting equipment, H-beams and pipes usually require independent cutting devices: Most H-beam cutting machines use laser or flame cutting, but they can only meet the cutting of H-beams and flat plates. Pipe cutting requires special pipe cutting equipment, such as circular saws or band saws. This separate design causes the following problems: 1. High equipment cost: H-beam cutting machines cannot cut round pipes, and enterprises need to purchase two sets of equipment, increasing capital investment; 2. Large floor area: The two sets of equipment need to be installed independently, occupying more production space; 3. Low efficiency: When switching materials, the equipment needs to be adjusted or replaced, affecting the processing continuity; 4. Limited functions: Traditional equipment is difficult to meet the cutting requirements of large-diameter pipes or complex angles. Summary of the Invention

[0003] In order to solve at least one of the above technical problems and develop an integrated device that can achieve efficient cutting of H-beams and pipes while reducing equipment costs and space requirements, this application provides an H-beam and pipe cutting device.

[0004] This application provides an H-beam and pipe cutting device, including an H-beam cutting station, a pipe cutting station, and a laser cutting mechanism. The H-beam cutting station and the pipe cutting station are both provided with a plurality of support bases arranged in a row. A fixing component for fixing the H-beam is detachably installed on the support base of the H-beam cutting station. A pipe support frame is detachably installed on the support base of the pipe cutting station. The pipe cutting station is also detachably installed with a clamping component for fixing the pipe. The laser cutting mechanism includes a laser cutter and an X-direction moving component for reciprocating the laser cutter between the two stations.

[0005] Optionally, the pipe support frame includes two support rods distributed in an "X" shape and a bidirectional screw for folding or unfolding the two support rods. The middle parts of the two support rods are hinged, and the top ends of the support rods are rotatably connected with rollers through rotating shafts.

[0006] Further optionally, the bottom ends of the support rods are rotatably connected with moving blocks and guiding and limiting wheels. The moving blocks are threadedly connected with the bidirectional screw. The pipe support frame further includes a guiding and limiting groove parallel to the axial direction of the bidirectional screw, and the guiding and limiting wheels are located in the guiding and limiting groove.

[0007] Further optionally, an "L"-shaped handle is fixedly installed at one end of the bidirectional screw.

[0008] Optionally, a plurality of adjusting bolts for adjusting the height of the support base are installed on the support base.

[0009] Optionally, the clamping assembly includes a chuck box and a chuck box base with adjustable height. The chuck box includes a chuck for clamping the pipe. A linear displacement assembly for driving the chuck box to move horizontally in a direction close to or away from the pipe support frame is arranged between the chuck box and the chuck box base.

[0010] Optionally, the X-direction moving assembly includes two parallel ground rails and a gantry workbench moving along the ground rails. The gantry base of the gantry workbench is slidably connected to the ground rails, and the laser cutter is installed on the gantry workbench.

[0011] Further optionally, a Y-direction moving assembly for driving the laser cutter to move along the cross beam is installed on the top cross beam of the gantry workbench.

[0012] Further optionally, the laser cutting mechanism further includes a Z-direction moving assembly for driving the laser cutter to lift. The Z-direction moving assembly is installed on the slider of the Y-direction moving assembly, and the laser cutter is installed at the lifting end of the Z-direction moving assembly.

[0013] Further optionally, a rotating motor set for driving the laser cutter to rotate is further installed at the lifting end of the Z-direction moving assembly. The rotating motor set includes a first motor and a second motor. The first motor is fixedly installed at the lifting end of the Z-direction moving assembly. The second motor is fixedly connected to the output end of the first motor, and the laser cutter is fixedly connected to the output end of the second motor.

[0014] In summary, the present invention includes at least one of the following beneficial technical effects:

[0015] 1. Integrated and modular design: The dual-station (H-shaped steel cutting station and pipe cutting station) designed in this application shares the same laser cutting mechanism, greatly reducing the floor area and purchase cost of the equipment; the pipe support frame and clamping assembly of the pipe cutting station are detachable, facilitating the switch to a pure H-shaped steel processing mode and improving the flexibility of the equipment.

[0016] 2. High-precision and multi-angle cutting: The three-dimensional five-axis laser cutting (X / Y / Z-axis movement + dual-motor rotation) designed in this application supports complex cross-section and bevel cutting, with an accuracy of ±0.1 mm.

[0017] 3. Strong adaptability: This application can process H-shaped steels and pipes with different specifications within a certain range, covering the mainstream industrial requirements; by replacing the pipe support frame and clamping assembly, it can be extended to the cutting of other special-shaped materials;

[0018] 4. Good working reliability: Through the linkage design of the bidirectional screw, two support rods distributed in an "X" shape, and the rollers, this application can not only ensure that the pipe cutting station adapts to pipes of different specifications within a certain range, but also effectively reduce the rotational torque and surface friction of the pipes, reducing the risk of pipe scratches during loading, unloading, and processing.

[0019] 5. High-efficiency production: The laser cutting speed adopted in this application is relatively high, and the station switching time is short, resulting in a substantial improvement in the overall efficiency; the modular design simplifies maintenance, and the failure rate is reduced by 20%.

[0020] 6. Low-cost upgrade: The existing double-station H-shaped steel cutting equipment can be upgraded to a composite cutting device by installing a pipe support frame and a clamping component at one of the stations, saving 60% of the transformation cost. Brief Description of the Drawings

[0029] The following further elaborates on this application in conjunction with the accompanying drawings and embodiments.

[0030] As Figure 1 and Figure 2 shown, the H-beam and pipe cutting device of this application includes an H-beam cutting station 1, a pipe cutting station 2, and a laser cutting mechanism 7. A plurality of support bases 3 arranged in a row are provided at both the H-beam cutting station 1 and the pipe cutting station 2. A fixing component 4 for fixing the H-beam 8 is detachably installed on the support base 3 of the H-beam cutting station 1. A pipe support frame 5 is detachably installed on the support base 3 of the pipe cutting station 2, and a clamping component 6 for fixing the pipe 9 is also detachably installed at the pipe cutting station 2. The laser cutting mechanism 7 includes a laser cutter 71 and an X-direction moving component 72 for reciprocally moving the laser cutter 71 between the two stations.

[0031] When the H-beam and pipe cutting device of this application is in use, first load the H-beam 8 onto the H-beam cutting station 1 and load the pipe 9 onto the pipe cutting station 2; then, drive the laser cutter 71 to move to the pipe cutting station 2 by the X-direction moving component 72 to perform cutting on the pipe 9; then, drive the laser cutter 71 to move to the H-beam cutting station 1 by the X-direction moving component 72 to perform cutting on the H-beam 8, and at the same time load and unload the pipe cutting station 2 where the cutting has been completed; then, drive the laser cutter 71 to move to the pipe cutting station 2 by the X-direction moving component 72 to perform cutting on the pipe 9, and at the same time load and unload the H-beam cutting station 1 where the cutting has been completed... until the rapid switching / continuous cutting of the H-beam 8 and the pipe 9 is completed.

[0032] In this application, the fixing component 4 for fixing the H-beam 8 can adopt any mechanism in the prior art, such as a web bearing seat bolted to the support base 3, as long as it can fix H-beams 8 of different specifications within a certain range.

[0033] The following are the embodiments of this application

[0034] Embodiment 1

[0035] The H-beam and pipe cutting device of this embodiment has basically the same basic structure as the H-beam and pipe cutting device of this application, with the difference lying in the specific structures of the pipe support frame 5 and the clamping component 6 at the pipe cutting station 2.

[0036] As Figure 3 and Figure 4As shown, considering the comprehensive factors of operation convenience, running accuracy and working reliability, the pipe support frame 5 of this embodiment includes two support rods 51 distributed in an "X" shape and a bidirectional screw 52 for folding or unfolding the two support rods 51. The middle parts of the two support rods 51 are hinged, and the top ends of the support rods 51 are rotatably connected with rollers 53 through rotating shafts. The bottom ends of the support rods 51 are rotatably connected with moving blocks 54 and guiding and limiting wheels 55. The moving blocks 54 are threadedly connected with the bidirectional screw 52. The pipe support frame 5 further includes a guiding and limiting groove 56 parallel to the axial direction of the bidirectional screw 52, and the guiding and limiting wheels 55 are located in the guiding and limiting groove 56. One end of the bidirectional screw 52 is fixedly installed with an "L"-shaped handle 57 to drive the bidirectional screw 52 to rotate by rotating the handle 57, which is not only labor-saving but also has a lower usage cost.

[0037] In this embodiment, by setting two support rods 51 distributed in an "X" shape and components such as rollers 53 and bidirectional screw 52 used in cooperation with the support rods 51, it can not only effectively and stably support the pipe 9 (radially), but also greatly reduce the rotation torque of the pipe 9, reduce friction and resistance, and then reduce the risk of scratching the pipe 9 during loading, unloading and processing. In addition, it can improve the practicability and flexibility of the device and realize rapid adjustment of the distance between the rollers 53 to adapt to pipes 9 with different pipe diameters (such as 100 mm to 600 mm) within a certain range. This embodiment adopts the guiding and limiting wheels 55 and the guiding and limiting groove 56 that work together to ensure the stable movement track of the moving blocks 54 and the support rods 51 while significantly improving the bearing capacity of the "X"-shaped support structure and extending the service life of the device.

[0038] As Figure 2 shown, the number of the pipe support frames 5 of this embodiment is 4, that is, the number of support bases 3 at the pipe cutting station 2 is 8, but only 4 of the support bases 3 are installed with pipe support frames 5. In actual use, the position (the distance between two adjacent pipe support frames 5) and / or the number of the pipe support frames 5 can be adjusted according to the length and the number of cuttings of the pipe 9 to be cut. To ensure stable support of the pipe 9 while reducing the operation time and frequency of adjusting the distance between the rollers 53 when replacing pipes 9 with different pipe diameters. At the same time, it also shows that the pipe cutting station 2 of this application is adapted to pipes 9 with different lengths within a certain range.

[0039] As Figure 6As shown in the figure, the clamping assembly 6 of this embodiment includes a chuck box 61 and a chuck box base 62 with adjustable height. The chuck box 61 includes a chuck 611 for clamping the pipe 9. A linear displacement assembly is provided between the chuck box 61 and the chuck box base 62 for driving the chuck box 61 to horizontally move in a direction close to or away from the pipe support frame 5. The linear displacement assembly includes a cylinder 63 fixedly installed on the chuck box base 62 and two slide rails 64, and a slider 65 fixedly installed on the chuck box 61 and slidably engaged with the slide rails 64; the end of the telescopic rod of the cylinder 63 away from the cylinder body is connected to the chuck box 61.

[0040] The chuck 611 includes a chuck body, movable jaws and a jaw drive mechanism, which clamps and positions the pipe 9 by the radial movement of the movable jaws evenly distributed on the chuck body. It is a relatively mature prior art and will not be elaborated here.

[0041] The chuck 611 of this embodiment is a pneumatic chuck. Using a pneumatic chuck not only has a stable and adjustable clamping force, but also can greatly improve production efficiency and reduce the labor intensity of workers at the same time.

[0042] The clamping assembly 6 designed with the above structure in this embodiment can not only effectively fix the pipe 9, but also has high positioning accuracy.

[0043] When the pipe cutting station 2 of this embodiment is in use, first adjust the distance between the two rollers 53 of the pipe support frame 5 according to the diameter of the pipe 9 to be cut, that is, the staff rotates the handle 57 to drive the bidirectional screw 52 to rotate, driving the two moving blocks 54 on both sides to move towards or away from each other. The moving block 54 drives the bottom end of the support rod 51, so that the two support rods 51 distributed in an "X" shape are closed or unfolded, thereby realizing the adjustment of the distance between the rollers 53. During the adjustment process, the guiding and limiting wheel 55 moves along the guiding and limiting groove 56 to ensure the stable movement track of the support rod 51; then the pipe 9 is loaded onto the pipe support frame 5. The multiple groups of rollers 53 not only effectively support the pipe 9 (radially), but also can effectively reduce the rotation torque and surface scratch rate of the pipe 9; then adjust the height of the chuck box base 62 to ensure the concentricity of the pipe 9; then the cylinder 63 acts, driving the chuck box 61 to horizontally move along the slide rail 64 to the position of the pipe 9 to a preset position (axial positioning); finally, the movable jaws of the chuck 611 move to clamp and position the pipe 9. At this time, the laser cutting mechanism 7 can cut and process the pipe 9.

[0044] Embodiment 2

[0045] The H-shaped steel and pipe cutting device of this embodiment is basically the same as the structure of Embodiment 1, except that the height of the support base 3 is adjustable.

[0046] As Figure 3 andFigure 5 As shown, a plurality of adjusting bolts 31 for adjusting the height of the support base 3 are installed on the support base 3. This is to adapt to H-beams of different specifications, facilitate meeting the requirements of different support heights, and at the same time facilitate clamping with the chuck 611 to ensure the concentricity of the pipe 9.

[0047] Embodiment 3

[0048] The H-beam and pipe cutting device of this embodiment is basically the same as that of Embodiment 2, except for the specific structure of the laser cutting mechanism 7.

[0049] As Figure 7 shown, the X-direction moving assembly 72 includes two parallel ground rails 721 and a gantry workbench 722 that moves along the ground rails 721. The gantry base 723 of the gantry workbench 722 is slidably connected to the ground rails 721, and the laser cutter 71 is installed on the gantry workbench 722. A Y-direction moving assembly 73 for driving the laser cutter 71 to move along the crossbeam is installed on the top crossbeam of the gantry workbench 722. The laser cutting mechanism 7 further includes a Z-direction moving assembly 74 for driving the laser cutter 71 to lift and lower. The Z-direction moving assembly 74 is installed on the slider of the Y-direction moving assembly 73, and the laser cutter 71 is installed at the lifting end of the Z-direction moving assembly 74.

[0050] In this embodiment, the X-direction moving assembly 72, Y-direction moving assembly 73, and Z-direction moving assembly for driving the laser cutter 71 to move in the X / Y / Z axes can adopt any driving mechanism in the prior art, such as a gear-rack driving mechanism powered by a motor, a screw-screw driving mechanism powered by a motor, and a hydraulic driving mechanism, etc.

[0051] A rotating motor set for driving the laser cutter 71 to rotate is further installed at the lifting end of the Z-direction moving assembly 74 to adjust the cutting angle of the laser cutter 71 to adapt to the cutting of different surfaces on the steel member. The rotating motor set includes a first motor 75 and a second motor 76. The first motor 75 is fixedly installed at the lifting end of the Z-direction moving assembly 74, the second motor 76 is fixedly connected to the output end of the first motor 75, and the laser cutter 71 is fixedly connected to the output end of the second motor 76.

[0052] The laser cutting mechanism 7 adopts the three-dimensional five-axis laser cutting structure (X / Y / Z axis movement + double-motor rotation) designed in this embodiment, which can not only achieve rapid switching / continuous cutting of H-beams 8 and pipes 9, but also support complex cross-section and bevel cutting, with an accuracy of ±0.1 mm.

[0053] In this application, the devices and components for which the structure is not described are all commercially available devices or components. The parts not elaborated in detail in this specification all belong to the prior art.

[0054] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
