Description

Technical Field

[0001] The invention relates to the technical field of arc cutting, in particular to a steel plate arc cutting device for building construction. Background Art

[0002] Arc cutting devices for steel plates used in construction utilize an arc (temperatures of up to 3,000-15,000°C) generated between an electrode and a steel plate to partially melt the plate and form an incision. Compressed air or plasma gas is then used to blow away the slag. These devices are suitable for use in applications such as building steel structures and special-shaped plates, and are particularly adept at processing conductive metals such as carbon steel and stainless steel.

[0003] Chinese patent publication number CN117444356B discloses a bellows arc cutting device, comprising a discharge needle, a fixing plate, a pressure head housing, a pressure head liner, a sealing assembly, and an elastic member. This invention enables the discharge needle to follow the cutting area, enabling the bellows to be cut using an existing cutting table, reducing the performance requirements of the cutting table. Furthermore, the pressure head housing and the pressure head liner protect the discharge needle, preventing damage from collisions.

[0004] Chinese patent publication number CN116252022B discloses an arc cutting machine for earthquake rescue, comprising a gun head holder, an air inlet I, a ceramic sleeve, and a cutting nozzle. Cooling airflow entering the inner cavity of the ceramic sleeve impacts the fan blades, causing the rotating seat to continuously rotate the direction-changing magnet. During this rotation, the direction-changing magnet creates a repulsive (attractive) reaction with magnet seats at different positions. This force exerted on the magnet seats drives the extrusion block deeper (farther) into the inner cavity of the cutting nozzle, causing the inner cavity of the cutting nozzle to continuously shrink (increase), compressing the gas within the cutting nozzle (inhaling the gas), increasing the ionized gas density within the cutting nozzle, and increasing the amount of gas ionization per unit time.

[0005] The above-mentioned and similar existing technologies can, to a certain extent, solve the problem of material cutting effect. However, existing arc cutting devices usually require manual or independent workstations to complete surface cleaning (such as oil stains and oxide layers) before starting the cutting process. This step-by-step operation prolongs the processing cycle, and manual intervention easily introduces the risk of secondary contamination. After cutting, only the burrs on the upper surface are usually treated, and the steel plate needs to be flipped over by a robot or manually for bottom surface treatment. The steel plate flipping process not only causes scratches on the workpiece surface, but may also scratch the operator. In addition, the arc cutting device and cleaning components are often driven by independent motors, which increases energy consumption and the frequency of equipment failure maintenance.

[0006] In view of this situation, the present invention provides an arc cutting device for steel plates for construction, the purpose of which is to clean the steel plates while cutting them, clean the burrs generated on the two end faces of the steel plates, and grind the cut cross-section of the steel plates, so as to reduce the impact of impurities on the cutting quality and burrs on the sealing and assembly accuracy of the steel plates, and at the same time avoid the safety hazards posed by burrs to workers.

Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0037] Specifically, the brush roller 75 is used to clean burrs on both sides of the steel plate to improve the precision of the steel plate and prevent the burrs from scratching the staff. The cleaning roller 76 is used to clean the steel plate before the arc cutting machine 5 cuts the steel plate to improve the stability of the arc and the cutting accuracy. The fixed frame 711 is used to fix the guide mechanism 8 so that the cleaning component 7 can move together with the arc cutting machine 5. The first mounting frame 712 and the second mounting frame 721 are used to connect the fixed frame 711 and install the transmission component 74, the brush roller 75 and the cleaning roller 76.

[0038] In this embodiment, the side wall grinding member 73 includes a special-shaped block 731, the upper and lower ends of the special-shaped block 731 are respectively fixedly connected to the first mounting frame 712 and the second mounting frame 721 on the side close to the arc cutting machine 5, the grinding roller 732 is rotatably mounted inside the special-shaped block, and is symmetrically arranged about the center of the special-shaped block 731, the fixed block 733 is fixedly mounted on one side of the second mounting frame 721, the bottom end of the grinding roller 732 is fixedly connected to a worm gear 734 through a rotating shaft, the worm gear 734 is meshed with a worm 735 on the side close to the second mounting frame 721, the worm 735 is rotatably mounted inside the second mounting frame 721, and the end of the worm 735 away from the worm gear 734 passes through the outside of the second mounting frame 721 and is fixedly mounted with a third gear 736, and the two ends of the connecting block 737 are respectively fixedly mounted on the first mounting frame 712 and the second mounting frame 721 on the side away from the special-shaped block 731.

[0039] Specifically, the special-shaped block 731 is used to stretch the cut steel plate, so as to facilitate the subsequent cleaning component 7 to clean the steel plate. At the same time, the special-shaped block 731 and the connecting block 737 are used to connect the first cleaning member 71 and the second cleaning member 72. The grinding roller 732 is used to grind the cut cross-section of the steel plate after stretching to improve the surface quality and assembly accuracy of the steel plate. The worm gear 734 cooperates with the worm 735 to transmit power through the third gear 736. The third gear 736 is engaged with the second gear 745 to transmit the power of the transmission component 74 to the grinding roller 732. The fixing block 733 is used to fix the bottom of the worm gear 734. The special-shaped block 731 is set to a triangle to facilitate stretching the steel plate.

[0040] In this embodiment, the transmission assembly 74 also includes a first planetary gear 741, and the first planetary gear 741 is symmetrically arranged about the center of the first mounting frame 712, and the first gear 742 is fixedly connected to the side of the first planetary gear 741 away from the first mounting frame 712, and the sliding member 743 is fixedly installed on the side of the first gear 742 away from the first planetary gear 741, the second planetary gear 744 is symmetrically arranged about the center of the second mounting frame 721, and the second planetary gear 744 is fixedly connected to the side of the second mounting frame 721 away from the second gear 745, the first rack 746 is located at the bottom end of the shell 4 and is symmetrically arranged about the center of the shell 4, the second rack 747 is fixedly installed inside the placement groove 12, and adjustment members 748 are provided at both ends of the first rack 746 and the second rack 747.

[0041] Specifically, the first planetary gear 741 and the second planetary gear 744 are used to transmit power to the brush roller 75 and the cleaning roller 76. At the same time, the planetary gears can further increase the power to improve the working efficiency of the cleaning component 7. The first gear 742 is engaged with the first rack 746 when the arc cutting machine 5 is reset, thereby driving the first cleaning member 71 to clean the burrs on the surface of the steel plate. The sliding member 743 can cooperate with the second slide groove 84 to slide during the process of the arc cutting machine 5 cutting the steel plate, and at the same time increase the stability of the cleaning component 7. The second gear 745 is engaged with the first rack 746 when the arc cutting machine 5 cuts the steel plate, and the cleaning roller 76 is used to clean impurities on the surface of the steel plate. When the arc cutting machine 5 is reset, it is engaged with the second rack 747, which can drive the brush roller 75 to clean the burrs on the bottom surface of the steel plate. The adjusting member is used to help the gear and the rack engage.

[0042] In this embodiment, the guide mechanism 8 includes a connecting rod 81, and the connecting rod 81 is fixedly installed inside the fixed frame 711. Rollers 82 are symmetrically arranged at both ends of the fixed rod 11. The first slide groove 83 is opened inside the shell 4, and two groups are symmetrically arranged about the shell 4. The second slide groove 84 is opened inside the shell 4 and is located below the first slide groove 83. The second slide groove 84 is symmetrically arranged in two groups about the shell 4, and a slide rail 831 is opened inside the second slide groove 84.

[0043] Specifically, the connecting rod 81 is used to connect the adjustment component 6 and the fixed frame 711, so that the cleaning component 7 can adjust the longitudinal position according to the adjustment component 6. The roller 82 is slidably connected with the slide rail 831 to facilitate the movement of the cleaning component 7 according to the arc cutting machine 5. The second slide groove 84 is used to facilitate the sliding of the cleaning component 7 by cooperating with the sliding member 743 when the arc cutting machine 5 cuts the steel plate.

[0044] Working principle: The initial state is as follows: Figure 2As shown, first place the steel plate on the surface of the workbench 1 in the direction of the desired cutting, then start the arc cutting machine 5 and the screw assembly 3 at the same time, first start the drive motor to drive the screw to rotate forward, then the screw rotation drives the slider to move linearly, and further drives the arc cutting machine 5 to move through the slider, and as the arc cutting machine 5 moves, the cleaning assembly 7 is driven to move through the guide mechanism 8, first, the connecting rod 81 drives the roller 82 to cooperate with the slide rail 831 to slide in the first slide groove 83, and then the second gear 745 is connected to the first rack 746 through the adjusting member 748. The meshing connection is then driven by the second gear 745 to rotate the second planetary gear 744, and then the brush roller 75 provided inside the second cleaning member 72 rotates to drive the cleaning roller 76 to rotate. At the same time, the first cleaning member 71 slides inside the second slide groove 84 through the sliding member 743 installed on one side of the first gear 742. Further, as the arc cutting machine 5 moves, the area to be cut on the surface of the steel plate is first cleaned by the cleaning roller 76, and then the arc cutting machine 5 cuts the steel plate to avoid the arc stability and cutting quality being affected by impurities carried on the surface of the steel plate.

[0045] After the arc cutting machine 5 completes the cutting of the steel plate, the arc cutting machine 5 continues to move forward, the second gear 745 disengages from the first rack 746, and then the guide mechanism 8 drives the cleaning assembly 7 to adjust longitudinally through the special shape of the first slide 83 and in conjunction with the second slide 84 and the adjustment mechanism 6, so that the first cleaning member 71 moves to the top of the steel plate and the second cleaning member 72 moves to the bottom of the steel plate. Then the driving motor is reversed to drive the lead screw to reverse, and the arc cutting machine 5 is driven to reset through the slider, and then the cleaning assembly 7 is driven to move through the adjustment assembly 6 and the guide mechanism 8, and the connecting rod 81 is connected to the cleaning assembly 7. The roller 82 is driven to slide inside the first slide groove 83. When it reaches the rightmost side, the first slide groove 83 will have a downward slope. The connecting rod 81 continues to move, thereby driving the sliding rod to slide inside the sleeve and compressing the spring to adjust the longitudinal position of the cleaning component 7. Then, as the cleaning component 7 moves, the first gear 742 is meshed with the first rack 746 through the adjusting member 748, and drives the brush roller 75 set inside the first cleaning member 71 to rotate through the first planetary gear 741. At the same time, the second gear 745 is meshed with the second rack 747 through the adjusting member 748, and is connected to the second cleaning member 71 through the adjusting member 748. The second planetary gear 744 drives the brush roller 75 provided inside the second cleaning member 72 to rotate. At the same time, the third gear 736 is connected to the second gear 745 and drives the worm gear 734 to rotate through the worm gear 735, thereby driving the grinding roller 732 to rotate. As the arc cutting machine 5 moves, the cleaning component 7 is driven to grind. First, the steel plate is opened by the anisotropic block 731 to facilitate the cleaning component 7 to grind the steel plate. Then, the cutting section of the steel plate is polished by the grinding roller 732. At the same time, the brush roller 75 provided inside the first cleaning member 71 is driven to remove burrs on the surface of the steel plate. The second cleaning assembly 72 is used to clean the steel plate, and at the same time, the brush roller 75 provided inside the second cleaning assembly 72 is driven to clean the burrs on the bottom of the steel plate. When the arc cutting machine 5 moves to the initial position, the grinding of the cut section of the steel plate can be completed, and the burrs on the upper and lower surfaces of the steel plate caused by cutting can be cleaned at the same time. Moreover, since the rotation directions of the brush roller 75 and the grinding roller 732 are opposite to the forward direction of the cleaning assembly 7, the friction between the brush roller 75, the grinding roller 732 and the steel plate is increased, thereby further improving the grinding effect of the cut section of the steel plate and the cleaning effect of the burrs on the surface of the steel plate.

[0046] Furthermore, when the steel plate needs to be cut again, the connecting rod 81 is located at the leftmost side of the first slide groove 83. Then, when the arc cutting machine 5 moves, the leftmost side of the first slide groove 83 is provided with an upward slope. Then, the spring loses its force and resets, thereby driving the cleaning component 7 to adjust its longitudinal position so that the second cleaning component 72 is located on the surface of the steel plate, and then subsequent processing can be carried out.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention.
