AI Technical Summary
When cutting irregularly shaped steel products, existing 3D laser cutting technology is prone to slippage, especially for irregularly shaped steel structures with small bottom areas, which can lead to instability of the center of gravity, potentially causing misalignment of the cutting path or damage to the equipment.

Abstract
Description
Technical Field
[0001] This invention relates to the field of laser cutting technology, specifically to a cutting device for processing irregularly shaped steel products. Background Technology
[0002] Three-dimensional laser cutting technology is a high-precision and highly flexible processing method. It uses a laser beam to move freely along three coordinate axes to cut, drill, and mark materials with complex three-dimensional shapes. The basic principle of this technology is to use the high energy density of the laser to locally heat the material to a melting or vaporization temperature in a non-contact manner, and then achieve the desired shape by controlling the position and intensity of the laser beam.
[0003] Three-dimensional laser cutting offers greater freedom for irregularly shaped steel products. However, when cutting complex irregular parts, as the material is gradually separated, the center of gravity of the remaining part may change abruptly. If it is not securely fixed, the workpiece may slide or tip over on the worktable, causing the cutting path to be misaligned, resulting in scrap, or even colliding with the cutting head and damaging the equipment.
[0004] Existing workbenches have high-density air holes on the table surface, which use vacuum negative pressure to adsorb steel products onto the workbench. However, for large-volume irregular steel structure materials with small bottom contact surfaces, vacuum negative pressure will accelerate the tilting of the cut products and cause the materials to shift.
[0005] To address the aforementioned technical deficiencies, a solution is proposed. Summary of the Invention
[0006] This invention provides a cutting device for processing irregular steel products, which solves the problem of unstable center of gravity and easy slippage after cutting irregular steel structures with small bottom areas.
[0007] To achieve the goal of pre-fixing the bottom of irregularly shaped steel products with a small bottom area according to the cutting target and preventing the steel products from sliding after cutting, the present invention is achieved through the following technical solution: a cutting device for processing irregularly shaped steel products, including a machine body, a gantry frame provided on the machine body via a linear motor, an AC axis provided on the gantry frame via a linear motor and an electric telescopic rod, a laser cutting head fixedly installed on the AC axis, guide rails for sliding connection of the gantry frame fixedly connected on both sides of the machine body, a metal mesh and a base plate fixedly connected to the inner wall and bottom of the machine body respectively, and an operating cavity provided between the metal mesh and the base plate; An inverted cone is fixedly installed on the machine body, and a fixing mechanism is provided inside the inverted cone for fixing irregular steel products. The operating cavity is equipped with a driving mechanism, which is used to move and install the fixing mechanism. The driving mechanism includes an electric push rod II. The movable end of the electric push rod II is rotatably connected to a V-shaped spring. The end of the V-shaped spring away from the electric push rod II is fixedly connected to a limit cylinder and a contact cylinder from bottom to top. Two protrusions are integrally formed on the upper part of the contact cylinder. A movable block is slidably connected to the protrusion on the left side by a spring. A connecting rod is used to install the second mounting end of the electric actuator. A fixed cylinder is fixedly connected to the top of the connecting rod.

[0008] Furthermore, the inverted cone is made of silicone rubber, and linear slits are provided on the inverted cone.
[0009] Furthermore, the top of the contact cylinder is cone-shaped; The two movable ends of the electric actuator are rotatably connected to the V-shaped spring plate via a rotating table.
[0010] Furthermore, the chute includes, from bottom to top, a first vertical track, a first threaded track, a second vertical track, a second threaded track, a third vertical track, and a fourth vertical track. The first vertical track is connected to the first threaded track, which is a one-and-a-half-turn counterclockwise thread. The second vertical track is connected to the first threaded track, and the second threaded track is connected to the second vertical track, which is a half-turn counterclockwise thread. The upper and lower ends of the third vertical track are connected to the second threaded track and the first threaded track, respectively. The fourth vertical track is located on the same vertical line as the second vertical track, and the fourth vertical track is connected to the first threaded track.
[0011] Furthermore, the drive mechanism also includes a linear drive, which is fixed to the gantry frame by a mounting plate. The linear drive is equipped with a slider, which is slidably connected to a movable plate by an electric push rod. The movable plate is provided with a limiting groove that is fitted and slidably connected to the slider. A connecting rod is fixedly connected to the top of the movable plate, and a vacuum generator and a filter are fixedly installed on the top of the connecting rod. Both the contact cylinder and the limiting cylinder have through holes at their upper positions, and the through holes, the filter, and the vacuum generator are connected in sequence by flexible hoses.
[0012] Furthermore, the fixing mechanism includes an adsorption part and a base part; The adsorption part is used to fix the irregular steel product on the metal mesh, and the base part is used to help the adsorption part not to move during the installation process and to assist the operation of the drive mechanism. The adsorption part includes a vacuum suction cup, the bottom of which is fixed and has a tapered tube. The bottom end of the tapered tube has a limiting hole that fits into the contact cylinder and the protrusion. The limiting hole has a chamfer, and there are three chamfers, two of which are located on the upper sides of the fitting point between the limiting hole and the protrusion, and one is located on the lower right side of the fitting point between the limiting hole and the protrusion. A piston is movably slidably connected inside the tapered tube, and a sealing ring is fixed at the bottom of the inner wall of the tapered tube. When the piston moves to the bottom, the piston contacts the sealing ring.
[0013] Furthermore, the base includes a connecting block, and a rotating rod is rotatably connected to the bottom end of the connecting block via a spring shaft. A gear is fixedly connected to the end of the rotating rod away from the connecting block. The bottom of the outer wall of the tapered tube is rotatably connected to a rotating rod three via a spring shaft two. A gear two is fixedly connected to the rotating rod three. When the base is lowered, gear two meshes with gear one. The end of the rotating rod three away from the tapered tube is rotatably connected to the rotating rod two via the spring shaft three. The rotating rod two is fixedly connected to the gear three. When the base is retracted, the gear three meshes with the gear one. The bottom of the rotating rod two has a movable groove, in which a round block is movably connected.

[0015] The present invention has the following beneficial effects: This cutting equipment for processing irregularly shaped steel products uses rotating rods two and three to pre-set the suction cup adsorption position. The vacuum suction cup then adsorbs the bottom of the irregularly shaped steel product, adsorbing and fixing it in place, ensuring the center of gravity remains unchanged after cutting. Simultaneously, the equipment's independent fixing mechanism, along with the foldable nature of rotating rods two and three, allows for flexible adjustment of the number of fixing points based on the production quantity of irregularly shaped steel products. Through the different combinations of a set of structures—including the contact cylinder, tapered tube, piston, V-shaped spring, sliding ball, and fixing cylinder, especially the groove inside the fixing cylinder—the equipment enables the removal and installation of the fixing mechanism, the erection of the base, and the vacuum suction cup's vacuum extraction and degassing. During the degassing process, the piston drives the connecting block to move, simultaneously lowering the base. Different meshing relationships between gears in different states allow for the retraction and changing of the rotating rod's support state, all enhancing the fixation of the irregularly shaped steel structure after cutting.
[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Link 7 is used to install the mounting end of electric actuator 28. A fixed cylinder 25 is fixedly connected to the top of link 7. A sliding groove 2501 is opened inside the fixed cylinder 25. A sliding ball 27 is fixedly connected to the V-shaped spring piece 26. The sliding ball 27 is movably slidably connected to the sliding groove 2501.
[0027] The slide 2501 includes, from bottom to top, a first vertical track, a first threaded track, a second vertical track, a second threaded track, a third vertical track, and a fourth vertical track.

[0028] The fixing mechanism includes an adsorption part and a base part. The adsorption part is used to fix the irregular steel product on the metal mesh 107. The base part is used to assist the adsorption part in preventing displacement during installation and to assist the operation of the drive mechanism. The adsorption part includes a vacuum suction cup 14. The bottom of the vacuum suction cup 14 is fixed and has a tapered tube 11 through it. The bottom end of the tapered tube 11 has a limiting hole that fits into the contact cylinder 10 and the protrusion 1002. The limiting hole has a chamfer 1101. There are three chamfers 1101, two of which are located on the upper sides of the fitting point between the limiting hole and the protrusion 1002, and one is located on the lower right side of the fitting point between the limiting hole and the protrusion 1002.
[0029] A piston 12 is movably slidably connected inside the tapered tube 11, and a sealing ring 13 is fixed at the bottom of the inner wall of the tapered tube 11. When the piston 12 moves to the bottom, the piston 12 contacts the sealing ring 13.
[0030] The base includes a connecting block 15. The bottom end of the connecting block 15 is rotatably connected to a rotating rod 16 via a spring shaft.

[0032] The drive mechanism also includes a linear drive 3, which is fixed to the gantry frame 102 by a mounting plate 2. The linear drive 3 is equipped with a slider 4, which is slidably connected to a movable plate 6 by an electric push rod 5. The movable plate 6 is provided with a limiting groove that is fitted and slidably connected to the slider 4. A connecting rod 7 is fixedly connected to the top of the movable plate 6.

One end of the other hose passes through the through hole on the limiting cylinder 1001 and is fixed in the through hole on the contact cylinder 10.
[0034] Working principle: According to the number of irregular steel products to be cut, the corresponding number of fixing mechanisms are stacked into the inverted cone 30. At this time, the gear 17 and gear 320 are in the meshing state. When it is necessary to remove the fixing mechanism in the inverted cone 30, the electric push rod 28 is moved to the bottom of the inverted cone 30. Then the electric push rod 28 is extended. The V-shaped spring 26 extends with the electric push rod 28 and slides in the fixing cylinder 25. At this time, the sliding ball 27 on the V-shaped spring 26 moves upward in the vertical track in the slide groove 2501. The limiting cylinder 1001, the contact cylinder 10, and the protrusion 1002 move upward with the V-shaped spring 26 in sequence.
[0035] The sliding ball 27 continues to move upward into the threaded track in the slide groove 2501. The sliding ball 27 slides along the threaded track, and the V-shaped spring 26 rotates 180° counterclockwise with the sliding ball 27. The limiting cylinder 1001, the contact cylinder 10, the protrusion 1002, and the movable block 24 rotate 180° counterclockwise with the V-shaped spring 26 in sequence.
[0036] The sliding ball 27 continues to move upward into the second vertical track in the slide groove 2501 and slides upward. At this time, the contact cylinder 10 contacts the tapered tube 11 in the lowest fixed mechanism inside the inverted cone cylinder 30. At the same time, the arc on the movable block 24 abuts against the chamfer 1101 of the tapered tube 11. The mutual compression of the two arcs compresses the spring 2401, and the movable block 24 sinks into the protrusion 1002. The movable block 24 moves synchronously with the protrusion 1002 into the tapered tube 11. The gap between the protrusion 1002 and the limiting cylinder 1001 is between the inner and outer walls of the tapered tube 11.
[0037] The sliding ball 27 continues to move upward into the second section of the threaded track in the slide groove 2501. The sliding ball 27 slides along the threaded track. The V-shaped spring 26 continues to rotate counterclockwise by 90° after the sliding ball 27 has already rotated 180° counterclockwise. At this time, the protrusion 1002 contacts the inner wall of the tapered tube 11. At this time, the contact cylinder 10 pushes the piston 12 upward. Due to the limiting effect of the inverted cone cylinder 30 on the rotating rod 19 and the rotating rod 29, the rotating rod 19 and the rotating rod 29 maintain their original state.
[0038] The second electric actuator 28 retracts, and the sliding ball 27 moves down to the third vertical track in the slide groove 2501 and slides downward until the sliding ball 27 slides down back to the middle position of the first threaded track. The V-shaped spring 26 slides down with the sliding ball 27. The limiting cylinder 1001, the contact cylinder 10, and the protrusion 1002 slide down with the V-shaped spring 26 in sequence. The tapered tube 11 slides down with the protrusion 1002 to the extrusion cone 30. The gap on the cone 30 is widened. The lower part of the tapered tube 11 moves with the protrusion 1002 to the bottom of the cone 30, pulling the protruding part below the rotating rod 29 out of the cone 30. At this time, the rotating rod 29 and the rotating rod 39 are still inside the cone 30.
[0039] When the lower part of the tapered tube 11 moves with the protrusion 1002 to below the inverted cone 30, the electric push rod 28 continues to retract. The sliding ball 27 continues to slide along the first threaded track at the middle position of the first threaded track. The V-shaped spring 26 rotates 90° counterclockwise with the sliding ball 27. The rotating table 2801, the limiting cylinder 1001, the contact cylinder 10, and the protrusion 1002 rotate 90° counterclockwise with the V-shaped spring 26 in sequence. The sliding ball 27 continues to slide down to the fourth end of the vertical track in the slide groove 2501 and continues to slide down. At this time, the arc of the movable block 24 contacts the chamfer 1101 on the tapered tube 11 located above. The two arc-shaped contact springs 2401 are pressed together. The movable block 24 is embedded in the protrusion 1002 along with the spring 2401. The movable block 24 moves out of the tapered tube 11 and returns to its original position.
[0040] Piston 12 moves downward by its weight, and rotating rod 16 moves downward with piston 12 through connecting block 15. The restoring force of the spring shaft between rotating rod 16 and connecting block 15 drives rotating rod 16 to rotate upward. Gear 17 rotates upward with rotating rod 16 until it engages with gear 3 20. During engagement, the reset of gear 17 pushes gear 3 20 towards piston 12, causing rotating rod 2 19 to rotate slightly towards piston 12 with gear 3 20. This slight rotation creates a gap between rotating rod 2 19 and inverted cone 30, allowing the fixing mechanism to be completely removed and moved above the contact cylinder 10. The restoring force of spring 2401 pushes the movable block 24 to support the bottom of the conical tube 11.
[0041] Move the electric actuator 28 to below the center of the bottom of the steel product to be cut, and extend the electric actuator 28 until the movable block 24 just passes through the lower chamfer 1101 in the tapered tube 11 and enters the tapered tube 11. At this time, the piston 12 moves upward with the contact cylinder 10, the connecting block 15 moves upward with the contact cylinder 10, the rotating rod 16 moves upward with the connecting block 15 and rotates downward, the gear 17 rotates downward with the rotating rod 16, the gear 3 20 loses its restraining force, and the restoring force of the spring shaft between the rotating rod 3 29 and the tapered tube 11, and between the rotating rod 2 19 and the rotating rod 3 29, causes... Rotating rod 3 29 rotates downwards, while rotating rod 2 19 rotates under its own weight until it is aligned with rotating rod 3 29. Support leg 23 remains perpendicular to base plate 105 under its own weight. During rotation, circular block 22 rotates with support leg 23. As support leg 23 contacts the ground, it moves upwards due to the force relative to the ground. Circular block 22 slides within the limiting groove below rotating rod 2 19. Gear 4 21 slides with circular block 22 until gear 4 21 meshes with gear 3 20. Gear 4 21 cannot rotate, thus temporarily locking support leg 23 and improving support stability. The three pairs of support legs 23 provide stable support for the tapered tube 11, and at this time, the vacuum suction cup 14 abuts against the metal mesh 107 and the bottom of the steel material.
[0042] After the support foot 23 contacts the base plate 105, the electric actuator 28 retracts, and gear 17 rotates until gear 218 meshes, further stabilizing the angle between the conical tube 11 and the rotating rod 29. The retraction of the electric actuator 28 causes the movable block 24 to move out of the conical tube 11, and the movable block 24 abuts against the bottom of the outer wall of the conical tube 11. At this time, the contact cylinder 10 enters the conical tube 11, that is, the vacuum generator 8's vacuuming end enters the conical tube 11, and the piston 12 and the conical tube... There is a gap between 11, and the protrusion 1002 abuts against the conical tube 11. The vacuum generator 8 is activated, and the vacuum generator 8 gradually brings the vacuum suction cup 14 into a vacuum state. At this time, the piston 12 is squeezed downward under the influence of the vacuum. The piston 12 indirectly squeezes the V-shaped spring 26 until the piston 12 and the sealing ring 13 are in close contact, realizing the adsorption of the vacuum suction cup 14 and the steel material. The rotating rod 29, the rotating rod 3, and the support foot 23 are supported between the vacuum suction cup 14 and the base plate 105.
[0043] Starting from the upper left, install the fixing mechanisms. After each fixing mechanism is installed, slide block 4 moves to the right, thus moving the contact cylinder 10 away from the conical tube 11. Then, move it to a corner beyond the machine body 101 to remove the fixing mechanism inside the inverted conical cylinder 30 for the next installation. Refer to the front-back, left-right, and right-side orientations. Figure 4 .
[0044] After the bottom of the material to be cut into irregular steel products is fixed, the AC axis 103, the linear motor for moving the gantry 102, the electric telescopic rod for moving the AC axis 103, and the linear motor are used to realize the three-dimensional five-axis control of the laser cutting head 104.
[0045] The electric actuator 28 is controlled by the linear drive 3 mounted on the gantry 102 to move left and right. The gantry 102 is moved by the linear motor that controls the movement of the gantry 102. The linear drive 3 moves forward and backward following the movement of the gantry 102. The electric actuator 5 is used for fine adjustment of the forward and backward position.
[0046] During material feeding, the electric push rod 28 is moved to the bottom of the piston 12 and extended, so that the contact cylinder 10 pushes open the piston 12 and retracts the fixing mechanism.
