Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled plasma cutting machines, in particular to a numerically controlled plasma cutting machine. Background Art

[0002] Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially melt (and evaporate) the metal at the workpiece cut, and uses the momentum of high-speed plasma to remove the molten metal to form a cut. A CNC plasma cutting machine refers to a machine tool or equipment that provides workpiece instructions to the control device of a CNC automatic cutting machine. The cutting machine can automatically cut according to a given program.

[0003] When using existing CNC plasma cutting machines, workers often find that existing CNC plasma cutting machines will produce a large amount of fine harmful smoke during the cutting process, such as acetaldehyde, rosin acid, isocyanate, nitrogen oxides, sulfides, hydrocarbons, etc. These smoke are rich in heavy metal particles, which are very harmful to the lungs and are extremely likely to cause pneumoconiosis. If they are not removed in time, they are easy to cause harm to the workers. Utility Model Content

[0006] The effect achieved by the above-mentioned components is: the cutting piece is placed firmly on the operating table, and the equipment is started through the operating panel, so that the cylinder slides on the gantry, driving the cutting gun to slide to the required cutting position, and then the cylinder is started. The cylinder drives the cutting gun to descend to cut the cutting piece, and the first motor is started. The output shaft of the first motor drives the threaded rod to rotate. Since the gantry slides in a limited position in the slide groove, the rotation of the threaded rod will drive the gantry to slide, thereby vertically cutting the cutting piece. The air pump can be started during the cutting process. The air pump absorbs the gas generated by the cutting into the gas collecting box to prevent harmful gases from causing damage to the staff, thereby avoiding the existing CNC plasma cutting machine from generating a large amount of fine harmful smoke during the cutting process. These smoke are rich in heavy metal particles, which are very harmful to the lungs and are extremely likely to cause pneumoconiosis. If they are not removed in time, they may cause harm to the staff.

[0007] Preferably, a fan is fixedly connected to a side of the gantry away from the air pump.

[0008] The effect achieved by the above components is: starting the fan, the fan blows the gas generated by cutting to the air pump end, which can enhance the efficiency of gas absorption.

[0009] Preferably, two door panels are slidably inserted on the gantry, and a connecting plate is fixedly connected to the two door panels.

[0010] The effect achieved by the above components is: the two connecting plates can be slid upward when placing the cutting piece, and the two connecting plates can be slid downward during the cutting process, so that the two connecting plates cover both sides of the gantry to prevent a large amount of harmful smoke from being lost in the dispersed air.

[0011] Preferably, a hydraulic cylinder is fixedly connected to the gantry, and a piston rod of the hydraulic cylinder is fixedly connected to the connecting plate.

[0012] The effect achieved by the above components is that the connecting plate can be driven to move up and down by starting the hydraulic cylinder, making the operation more convenient.

[0013] Preferably, a filter plate is fixedly connected to the air collecting box, and an air outlet is opened on the air collecting box, and the air outlet is located below the filter plate.

[0014] The effect achieved by the above components is that harmful smoke entering the gas collecting box will be filtered by the filter plate and then discharged from the air outlet.

[0015] Preferably, a clamping structure is provided on the operating table, and the clamping structure is mainly composed of two sliding grooves, both of which are opened on the operating table, and the sliding connection in the sliding groove is composed of a sliding block, and the two sliding blocks located on one side are commonly fixedly connected with a clamping block.

[0016] The effect achieved by the above components is: the cutting piece is placed on the operating table, and then the two clamping blocks can be slid to clamp and limit the cutting piece, so that the cutting piece is more stable during the cutting process.

[0017] Preferably, a bidirectional screw is rotatably connected in one of the sliding grooves, the bidirectional screw is threadedly connected to the sliding block, the two sections of thread on the bidirectional screw are in opposite directions, a second motor is fixedly connected to the operating table, and the output shaft of the second motor is fixedly connected to the bidirectional screw.

[0018] The effect achieved by the above components is: start the second motor, and the output shaft of the second motor drives the bidirectional screw to rotate. Since the sliding block slides in the sliding groove, the rotation of the bidirectional screw will drive the sliding block to slide. Since the two sections of the thread on the bidirectional screw are in opposite directions, the rotation of the bidirectional screw will drive the two clamping blocks to move closer to or away from each other.

[0019] Preferably, a rubber pad is fixedly connected to the clamping block.

[0020] The effect achieved by the above components is that the rubber pad can enhance the friction between the clamping block and the cutting piece, thereby enhancing the clamping effect on the cutting piece.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, by setting a dust suction structure, the air pump can be started during the cutting process, and the air pump absorbs the gas generated by the cutting into the air collecting box to prevent harmful gases from causing damage to the staff. The fan is started, and the fan blows the gas generated by the cutting to the air pump end, which can enhance the efficiency of gas absorption. When placing the cutting piece, the two connecting plates can be slid upward, and the two connecting plates can be slid downward during the cutting process, so that the two connecting plates block the two sides of the gantry to prevent a large amount of harmful smoke from being lost in the dispersed air. The hydraulic cylinder can be started to drive the connecting plates to move up and down, making the operation more convenient. The harmful smoke entering the air collecting box will be filtered by the filter plate and then discharged from the air outlet, thereby avoiding the existing CNC plasma cutting machine from generating a large amount of fine harmful smoke during the cutting process. These smoke are rich in heavy metal particles, which are very harmful to the lungs and are extremely likely to cause pneumoconiosis. If they are not removed in time, they are likely to cause harm to the staff. BRIEF DESCRIPTION OF THE DRAWINGS

An air collecting box 53 is fixedly connected to the operating table 1, and the air delivery pipe 52 is connected to the air collecting box 53. Slide grooves 510 are respectively provided on both sides of the operating table 1, and the slide grooves 510 are slidably connected to the gantry 2. A threaded rod 511 is rotatably connected in one of the slide grooves 510, and the threaded rod 511 is threadedly connected to the gantry 2. A first motor 512 is fixedly connected to the operating table 1, and the output shaft of the first motor 512 is fixedly connected to the threaded rod 511. The cutting piece is placed on the operating table 1, and the equipment is started through the operating panel, so that the cylinder 3 slides on the gantry 2, driving the cutting gun 4 to slide to the required cutting position, and then the cylinder 3 is started, and the cylinder 3 drives the cutting gun 4 to descend to cut the cutting piece, and the first motor 512 is started, and the output shaft of the first motor 512 drives the threaded rod 511 to rotate. Since the gantry 2 slides in the slide groove 510, the rotation of the threaded rod 511 will drive the gantry 2 to slide, so as to vertically cut the cutting piece. During the cutting process, the air pump 51 can be started, and the air pump 51 absorbs the gas generated by the cutting into the gas collecting box 53 to prevent harmful gases from causing harm to the staff. Damage is caused, thereby avoiding the existing CNC plasma cutting machine from generating a large amount of fine harmful smoke and dust during the cutting process. These smoke and dust are rich in heavy metal particles, which are very harmful to the lungs and are extremely likely to cause pneumoconiosis. If they are not removed in time, they are likely to cause harm to the staff. The side of the gantry 2 away from the air pump 51 is fixedly connected with a fan 54. The fan 54 is started, and the fan 54 blows the gas generated by cutting to the end of the air pump 51 to enhance the efficiency of gas absorption. Two door panels 55 are slidably inserted on the gantry 2. The two door panels 55 are fixedly connected with a connecting plate 56. When placing the cutting piece, the two connecting plates 56 can be slid upwards. 6. During the cutting process, the two connecting plates 56 can be slid downward so that the two connecting plates 56 can cover the two sides of the gantry 2 to prevent a large amount of harmful smoke from being lost in the dispersed air. A hydraulic cylinder 57 is fixedly connected to the gantry 2, and the piston rod of the hydraulic cylinder 57 is fixedly connected to the connecting plate 56. By starting the hydraulic cylinder 57, the connecting plate 56 can be driven to move up and down, making the operation more convenient. A filter plate 58 is fixedly connected to the air collecting box 53, and an air outlet 59 is opened on the air collecting box 53. The air outlet 59 is located below the filter plate 58. Harmful smoke entering the air collecting box 53 will be filtered by the filter plate 58 and then discharged from the air outlet 59.

[0029] Reference Figure 4The operating table 1 is provided with a clamping structure 6, which is mainly composed of two sliding grooves 61. The two sliding grooves 61 are both opened on the operating table 1. The sliding groove 61 is slidably connected by a sliding block 62. The two sliding blocks 62 on one side are fixedly connected with a clamping block 63. The cutting piece is placed on the operating table 1, and then the two clamping blocks 63 can be slid to clamp and limit the cutting piece, so that the cutting piece is more stable during the cutting process. A bidirectional screw 64 is rotatably connected in a sliding groove 61. The bidirectional screw 64 is threadedly connected to the sliding block 62. The two sections of the thread on the bidirectional screw 64 are in opposite directions. The operating table 1 is fixed. A second motor 65 is connected, and the output shaft of the second motor 65 is fixedly connected to the bidirectional screw 64. When the second motor 65 is started, the output shaft of the second motor 65 drives the bidirectional screw 64 to rotate. Since the sliding block 62 slides in the sliding groove 61, the rotation of the bidirectional screw 64 will drive the sliding block 62 to slide. Since the two sections of the thread on the bidirectional screw 64 are in opposite directions, the rotation of the bidirectional screw 64 will drive the two clamping blocks 63 to approach or move away from each other. A rubber pad 66 is fixedly connected to the clamping block 63. The rubber pad 66 can enhance the friction between the clamping block 63 and the cutting piece, thereby enhancing the clamping effect on the cutting piece.

[0030] Working principle: place the cutting piece on the operating table 1, start the equipment through the operating panel, make the cylinder 3 slide on the gantry 2, drive the cutting gun 4 to slide to the required cutting position, then start the cylinder 3, the cylinder 3 drives the cutting gun 4 to descend to cut the cutting piece, start the first motor 512, the output shaft of the first motor 512 drives the threaded rod 511 to rotate, because the gantry 2 slides in the slide groove 510, the rotation of the threaded rod 511 will drive the gantry 2 to slide, so as to vertically cut the cutting piece, and the air pump 51 can be started during the cutting process, and the air pump 51 absorbs the gas generated by the cutting into the gas collecting box 53 to prevent the harmful gas from causing harm to the staff, thereby avoiding the existing CNC plasma cutting machine from generating a large amount of fine harmful smoke during the cutting process. These smoke are rich in heavy metal particles, which are very harmful to the lungs and are extremely likely to cause pneumoconiosis. If they are not removed in time, they may cause harm to the staff, and the fan 54 is started, and the fan 54 blows the gas generated by the cutting to the end of the air pump 51, which can enhance the efficiency of gas absorption and release When placing the cutting piece, the two connecting plates 56 can be slid upwards, and during the cutting process, the two connecting plates 56 can be slid downwards, so that the two connecting plates 56 can block the two sides of the gantry 2 to prevent the harmful smoke from being lost in large quantities in the dispersed air. The hydraulic cylinder 57 can be started to drive the connecting plates 56 to move up and down, making the operation more convenient. The harmful smoke entering the air collecting box 53 will be filtered by the filter plate 58 and then discharged from the air outlet 59. The cutting piece is placed on the operating table 1, and then the two clamping blocks 63 can be slid to clamp the cutting piece. The limiting function makes the cutting piece more stable during the cutting process. The second motor 65 is started, and the output shaft of the second motor 65 drives the bidirectional screw 64 to rotate. Since the sliding block 62 slides in the sliding groove 61, the rotation of the bidirectional screw 64 will drive the sliding block 62 to slide. Since the two sections of the thread on the bidirectional screw 64 are in opposite directions, the rotation of the bidirectional screw 64 will drive the two clamping blocks 63 to move closer to or away from each other. The rubber pad 66 can enhance the friction between the clamping block 63 and the cutting piece, thereby enhancing the clamping effect on the cutting piece.
