Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment applications, and particularly to a plasma steel cutting device and a control method therefor. Background Art

[0002] In the steel processing industry, plasma cutting is a commonly used cutting method. Traditional plasma steel cutting devices have many problems. For example, it is difficult to ensure cutting accuracy. During the cutting process, due to the instability of the plasma arc and the change in the distance between the cutting head and the steel surface, it is easy to cause deviations and unevenness in the cut, resulting in low cutting efficiency. The moving speed of the cutting head and the plasma parameters cannot be adaptively adjusted according to the material and thickness of the steel, causing the cutting time to be too long. At the same time, the existing cutting devices also have deficiencies in terms of automation, with a lot of manual intervention, increasing the labor intensity and production cost. Therefore, there is an urgent need for a plasma steel cutting device and a control method that can overcome the above problems. For this reason, we have proposed a plasma steel cutting device and a control method. Summary of the Invention

[0013] A control method for a plasma steel cutting device, which is applicable to the plasma steel cutting device described in any one of the above. The method is as follows: Place the plasma steel on the support block inside the placement rack, and clamp and fix the steel through the pneumatic clamping assembly. After clamping and fixing, the third motor is started. The start of the third motor drives the synchronous rotation of the first pulley. The rotation of the first pulley drives the rotation of the second pulley through the belt. The rotation of the second pulley drives the rotation of the transmission rod. The rotation of the transmission rod drives the synchronous rotation of the second half gear and the first half gear. The rotation of the second half gear drives the rotation of the first driven gear. The rotation of the first driven gear drives the rotation of the reciprocating screw rod. The rotation of the reciprocating screw rod drives the linkage frame to move smoothly back and forth along the guide rod, and performs horizontal cutting on the steel through the reciprocating movement of the linkage frame; The start of the first motor drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the threaded rod. The rotation of the threaded rod drives the movement of the moving frame, and at the same time drives the push rod motor and the cutting gun to move synchronously. Adjustment processing for longitudinal cutting is performed through the movement of the cutting gun; The second motor is started to drive the rotation of the first driving gear, and is simultaneously meshed and driven with the second driven gear. The rotation of the second driven gear drives the rotation of the first worm. The rotation of the first worm drives the synchronous rotation of the first worm gear. The rotation of the first worm gear drives the rotation of the connecting rod, thereby driving the rotation of the fan blade. The cutting fumes generated during the cutting of the cutting gun are attracted through the rotation of the fan blade, so as to perform centralized collection and filtration processing on the fumes; When the second half gear meshes with the first driven gear, the first half gear does not mesh with the third driven gear, causing the second worm to remain stationary. The stationary state of the second worm keeps the drive roller stationary and the placement rack stationary, facilitating the cutting of steel by the cutting torch. After the linkage moves back and forth along the reciprocating lead screw, the cutting torch moves away from the inside of the placement rack. When the second half gear disengages from the teeth of the first driven gear, the first half gear simultaneously meshes with the third driven gear. When the rotation of the third driven gear drives the linkage rod to rotate, the rotation of the linkage rod drives the synchronous rotation of the third bevel gear. The rotation of the third bevel gear and the fourth bevel gear causes the fourth bevel gear to drive the rotation of the second worm. The rotation of the second worm drives the rotation of the second worm gear. The rotation of the second worm gear drives the rotation of the short shaft and simultaneously drives the rotation of the two drive rollers. The rotation of the drive rollers drives the rotation of the placement rack, and the steel placed inside is turned over through the rotation of the placement rack. After the placement rack finishes turning over, the first half gear disengages from the teeth of the third driven gear, causing the second worm to remain stationary. At the same time, the second half gear meshes with the first driven gear again for transmission processing, thereby driving the rotation of the reciprocating lead screw. The rotation of the reciprocating lead screw drives the linkage to move back and forth along the guide rod again, so as to perform cutting processing on the steel after turning it over.

[0014] Compared with the existing technology, the beneficial effects of the present invention are as follows: 1. By installing a horizontal adjustment mechanism, a vertical adjustment mechanism, a fume suction mechanism and a turning mechanism, the present invention performs horizontal and vertical cutting adjustment processing on steel, simultaneously sucks and discharges the fumes generated during cutting, and automatically turns over the steel to be cut; 2. By installing a driving mechanism and a linkage mechanism, the present invention performs power output and power transmission processing on the equipment. Among them, the driving mechanism starts through the third motor to drive the first pulley to rotate, and simultaneously drives the rotation of the second pulley through a belt. The rotation of the second pulley drives the rotation of the driven rod, and the rotation of the driven rod drives the respective rotations of the reciprocating lead screw and the linkage rod; In summary, the clamping of the steel to be cut, the adjustment of the cutting path, the fume treatment and the automatic turning over of this equipment are all completed through the cooperation of the motor and the transmission mechanism. The operator only needs to complete the feeding and parameter setting, reducing the labor intensity, reducing the defective rate caused by human errors, and at the same time being adaptable to assembly line operations, reducing the production cost.

A guide rod 203 is fixedly connected to the machine body 1, and the guide rod 203 is movably sleeved inside the guide hole. One end of the reciprocating lead screw 201 is fixedly connected with a first driven gear 204. The rotation of the reciprocating lead screw 201 drives the linkage frame 202 to move along the guide rod 203, and the steel is transversely cut through the reciprocating movement of the linkage frame 202; The vertical adjustment mechanism 3 includes a threaded rod 301 rotatably connected to the top of the linkage frame 202.

The output end of the push rod motor 303 is fixedly connected with a mounting plate 304. A cutting gun 305 is fixedly connected to the mounting plate 304, which is used for longitudinally cutting and adjusting the plasma steel. When the push rod motor 303 is started, it drives the mounting plate 304 to move, and at the same time drives the cutting gun 305 to move. By moving the cutting gun 305 to abut against the steel to be cut, it is convenient to cut steels of different thicknesses; The soot suction mechanism 4 includes a cover body 401 fixedly connected to the top of the machine body 1. Two connecting rods 402 are symmetrically and rotatably connected inside the cover body 401. One ends of the two connecting rods 402 are respectively fixedly connected with fan blades 403. The fan blades 403 are movably sleeved inside the cover body 401. The other ends of the two connecting rods 402 are respectively fixedly connected with first worm wheels 404. A plurality of smoke inlet grooves are formed in the front surface of the cover body 401 for sucking the plasma cutting fumes. A smoke exhaust port is formed in the back surface of the cover body 401 for discharging the cutting fumes. An external smoke purification guiding pipe is fixedly connected to the smoke exhaust port for sucking the fumes generated during the plasma steel cutting. A second motor 407 is fixedly connected to one side of the cover body 401. The output shaft of the second motor 407 is fixedly connected with a first driving gear 408. A first worm 405 is rotatably connected to one side of the cover body 401 corresponding to the two first worm wheels 404. One side of the first worm 405 is meshed and driven with the two first worm wheels 404. A second driven gear 406 is fixedly connected to one end of the first worm 405 corresponding to the first driving gear 408. One side of the second driven gear 406 is meshed and driven with the first driving gear 408. When the second motor 407 is started to drive the rotation of the first driving gear 408, the rotation of the first driving gear 408 drives the synchronous rotation of the second driven gear 406, and at the same time drives the rotation of the first worm 405. The rotation of the first worm 405 drives the rotation of the first worm wheel 404, and at the same time drives the rotation of the connecting rod 402. The rotation of the connecting rod 402 drives the synchronous rotation of the fan blade 403. The cutting fumes generated during cutting are sucked and processed through the rotation of the fan blade 403; It is worth mentioning that the fan blade 403 is driven by the second motor 407 to rotate. The harmful fumes generated by cutting are sucked through the smoke inlet grooves (front surface of the cover body 401), and are connected to an external purification device through the smoke exhaust port to achieve centralized filtration and discharge of the fumes, improve the working environment, and reduce the health risks of operators; The turning mechanism 6 includes a driven frame 601 rotatably connected to one side of the machine body 1. One side of the driven frame 601 is fixedly connected with a placement rack 602. Support blocks 603 and fixed blocks 604 are symmetrically and fixedly connected to both sides of the placement rack 602 respectively. An activity opening is formed in the support block 603, and a sliding roller 606 is rotatably connected inside the activity opening. A pneumatic clamping assembly 605 is installed on the fixed block 604. Two groups of balance plates 607 are symmetrically and fixedly connected inside the machine body 1. Two short shafts 608 are respectively rotatably connected to one side of the balance plate 607. One ends of the two short shafts 608 are respectively fixedly connected with driving rollers 609. An auxiliary roller 610 is rotatably connected to the other side of the balance plate 607. One sides of the driving roller 609 and the auxiliary roller 610 are respectively abutted against both sides of the placement rack 602. The other ends of the short shafts 608 are fixedly connected with second worm wheels 611. A second worm 612 is rotatably connected below the second worm wheel 611. One side of the second worm 612 is in meshing transmission with the second worm wheel 611, which is used for turning over during plasma steel cutting. The rotation of the short shaft 608 drives the synchronous rotation of the driving roller 609. The rotation of the driving roller 609 drives the placement rack 602 to perform a circular motion, and the steel is automatically turned over through the circular motion of the placement rack 602; The driving mechanism 5 includes a motor frame fixedly connected to the bottom of the machine body 1. A third motor 501 is fixedly connected to the motor frame. The output shaft of the third motor 501 is fixedly connected with a first belt pulley 502. A transmission rod 503 is rotatably connected inside the machine body 1. A second belt pulley 504 is fixedly connected to one end of the transmission rod 503 corresponding to the first belt pulley 502. The same belt 505 is in transmission connection between the second belt pulley 504 and the first belt pulley 502, which is used for power output to the lateral adjustment mechanism 2 and the turning mechanism 6. A linkage mechanism 7 is provided between the driving mechanism 5 and the turning mechanism 6 and the lateral adjustment mechanism 2. The start of the third motor 501 drives the rotation of the first belt pulley 502. The rotation of the first belt pulley 502 drives the rotation of the second belt pulley 504 through the belt 505, and at the same time drives the rotation of the transmission rod 503 for processing; It is worth mentioning that the third motor 501 drives the first belt pulley 502 and the second belt pulley 505 to rotate, and at the same time provides power for the lateral adjustment mechanism 2 and the turning mechanism 6, reducing independent driving components, simplifying the mechanical structure, and improving the power transmission efficiency.

[0020] In the present invention, the longitudinal adjustment mechanism 3 further includes a first bevel gear 306 fixedly connected to one end of the threaded rod 301, a first motor 307 fixedly connected to one side of the linkage frame 202. The output shaft of the first motor 307 is fixedly connected with a second bevel gear 308. One side of the second bevel gear 308 is meshed and driven with the first bevel gear 306. A guide block is fixedly connected to the bottom of the moving frame 302. A guide groove is provided above the linkage frame 202 corresponding to the guide block. The guide block is movably sleeved inside the guide groove. The start of the first motor 307 drives the rotation of the second bevel gear 308. The rotation of the second bevel gear 308 drives the rotation of the first bevel gear 306, and at the same time drives the threaded rod 301 to rotate. The rotation of the threaded rod 301 drives the moving frame 302 to move smoothly along the guide groove through the guide block; It is worth mentioning that the transverse cutting, longitudinal adjustment and fume suction can operate synchronously. For example, when the cutting gun moves horizontally, the fume suction mechanism 4 keeps working to avoid efficiency loss caused by waiting for flue gas treatment.

[0021] In the present invention, the linkage mechanism 7 includes a linkage rod 701 rotatably connected inside the machine body 1. One end of the linkage rod 701 is fixedly connected with a third driven gear 702. One end of the transmission rod 503 is fixedly connected with a first half gear 703 corresponding to the third driven gear 702. One side of the first half gear 703 is meshed and driven with the third driven gear 702. The other end of the linkage rod 701 is fixedly connected with a third bevel gear 704. A fourth bevel gear 705 is fixedly connected to the second worm 612 corresponding to the third bevel gear 704. One side of the fourth bevel gear 705 is meshed and driven with the third bevel gear 704. The other end of the transmission rod 503 is fixedly connected with a second half gear 706. One side of the second half gear 706 is meshed and driven with the first driven gear 204; It is worth mentioning that when the second half gear 706 rotates half a turn, the first driven gear 204 rotates at least four turns. When the first driven gear 204 rotates four turns, the linkage frame 202 moves along the reciprocating lead screw 201 for two trips. When the linkage frame 202 moves to the origin, the teeth of the second half gear 706 are separated from the teeth of the first driven gear 204, so that the second half gear 706 keeps idling for half a turn; When the second half gear 706 disengages from the teeth of the first driven gear 204, the first half gear 703 engages with the teeth of the third driven gear 702. When the first half gear 703 rotates half a turn, the third driven gear 702 also rotates several turns, thus facilitating the rotation of the driven frame 601. The rotation of the driven frame 601 drives the placement frame 602 to turn over. After the placement frame 602 has been turned over, the first half gear 703 disengages from the teeth of the third driven gear 702. At the same time, after the first half gear 703 disengages from the teeth of the third driven gear 702, the second half gear 706 engages with the teeth of the first driven gear 204 again, thereby driving the reciprocating lead screw 201 to rotate again, and driving the cutting torch 305 to perform a secondary horizontal cutting process on the turned-over steel; It is worth mentioning that by using the meshing logic of the half gears (703, 706) and bevel gears (704, 705), the time-sharing linkage of the cutting and turning-over actions is realized: When the second half gear 706 drives the horizontal cutting, the first half gear 703 disengages from the third driven gear 702 to ensure that the steel remains stable during the cutting process; After the cutting is completed, the first half gear 703 automatically engages, triggering the turning-over action, realizing the full-process automation of "cutting - turning over - cutting again", greatly shortening the auxiliary time and improving the production efficiency.

[0022] Embodiment 2 A control method for a plasma steel cutting device. In this embodiment, it is applicable to the above-mentioned plasma steel cutting device, and the method is as follows: Place the plasma steel on the support block 603 inside the placement frame 602, and clamp and fix the steel through the pneumatic clamping assembly 605. After clamping and fixing, the third motor 501 is started. The start of the third motor 501 drives the synchronous rotation of the first pulley 502. The rotation of the first pulley 502 drives the second pulley 504 to rotate through the belt 505. The rotation of the second pulley 504 drives the rotation of the transmission rod 503. The rotation of the transmission rod 503 drives the second half gear 706 and the first half gear 703 to rotate synchronously. The rotation of the second half gear 706 drives the rotation of the first driven gear 204. The rotation of the first driven gear 204 drives the rotation of the reciprocating lead screw 201. The rotation of the reciprocating lead screw 201 drives the linkage frame 202 to move reciprocally along the guide rod 203 smoothly, and performs a horizontal cutting process on the steel through the reciprocating movement of the linkage frame 202; The startup of the first motor 307 drives the rotation of the second bevel gear 308. The rotation of the second bevel gear 308 drives the rotation of the first bevel gear 306. The rotation of the first bevel gear 306 drives the rotation of the threaded rod 301. The rotation of the threaded rod 301 drives the movement of the moving frame 302, and simultaneously drives the push rod motor 303 and the cutting gun 305 to move synchronously. The movement of the cutting gun 305 is used for the adjustment process of longitudinal cutting; The startup of the second motor 407 drives the rotation of the first driving gear 408, and simultaneously meshes and drives with the second driven gear 406. The rotation of the second driven gear 406 drives the rotation of the first worm 405. The rotation of the first worm 405 drives the synchronous rotation of the first worm gear 404. The rotation of the first worm gear 404 drives the rotation of the connecting rod 402, thereby driving the rotation of the fan blade 403. The rotation of the fan blade 403 sucks the fumes generated during the cutting of the cutting gun 305, thereby performing centralized collection and filtration treatment on the fumes; When the second half gear 706 meshes with the first driven gear 204, the first half gear 703 does not mesh with the third driven gear 702, causing the second worm 612 to remain stationary. The stationary state of the second worm 612 causes the driving roller 609 to remain stationary, and at the same time causes the placement rack 602 to remain stationary, facilitating the cutting process of the cutting gun 305 on the steel. After the linkage frame 202 moves back and forth along the reciprocating lead screw 201, the cutting gun 305 moves away from the inside of the placement rack 602. When the second half gear 706 separates from the teeth of the first driven gear 204, at the same time, the first half gear 703 meshes with the third driven gear 702. When the rotation of the third driven gear 702 drives the link rod 701 to rotate, the rotation of the link rod 701 drives the synchronous rotation of the third bevel gear 704. The rotation of the third bevel gear 704 and the rotation of the fourth bevel gear 705. The rotation of the fourth bevel gear 705 drives the rotation of the second worm 612. The rotation of the second worm 612 drives the rotation of the second worm gear 611. The rotation of the second worm gear 611 drives the rotation of the short shaft 608, and simultaneously drives the rotation of the two driving rollers 609. The rotation of the driving rollers 609 drives the rotation of the placement rack 602. The rotation of the placement rack 602 flips the steel placed inside. After the placement rack 602 finishes flipping, the first half gear 703 separates from the teeth of the third driven gear 702, causing the second worm 612 to remain stationary. At the same time, the second half gear 706 meshes and drives with the first driven gear 204 again, thereby driving the rotation of the reciprocating lead screw 201. The rotation of the reciprocating lead screw 201 drives the linkage frame 202 to reciprocate along the guide rod 203 again, thereby performing the cutting process after the steel is flipped.

[0023] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.

10. A control method for a plasma steel cutting device, which is applicable to a plasma steel cutting device according to any one of the above claims 1-9, characterized in that, The method is as follows: Place the plasma steel on the support block (603) inside the placement rack (602), and clamp and fix the steel through the pneumatic clamping assembly (605). After clamping and fixing, the third motor (501) is started. The start of the third motor (501) drives the synchronous rotation of the first pulley (502). The rotation of the first pulley (502) drives the second pulley (504) to rotate through the belt (505). The rotation of the second pulley (504) drives the rotation of the transmission rod (503). The rotation of the transmission rod (503) drives the second half gear (706) and the first half gear (703) to rotate synchronously. The rotation of the second half gear (706) drives the rotation of the first driven gear (204). The rotation of the first driven gear (204) drives the rotation of the reciprocating lead screw (201). The rotation of the reciprocating lead screw (201) drives the linkage frame (202) to move reciprocally and smoothly along the guide rod (203). The steel is transversely cut through the reciprocating movement of the linkage frame (202); The start of the first motor (307) drives the rotation of the second bevel gear (308). The rotation of the second bevel gear (308) drives the rotation of the first bevel gear (306). The rotation of the first bevel gear (306) drives the rotation of the threaded rod (301). The rotation of the threaded rod (301) drives the moving frame (302) to move, and simultaneously drives the push rod motor (303) and the cutting torch (305) to move synchronously. The longitudinal cutting adjustment process is carried out through the movement of the cutting torch (305); The second motor (407) starts to drive the rotation of the first driving gear (408), and at the same time meshes with the second driven gear (406) for transmission. The rotation of the second driven gear (406) drives the rotation of the first worm (405). The rotation of the first worm (405) drives the synchronous rotation of the first worm gear (404). The rotation of the first worm gear (404) drives the rotation of the connecting rod (402), thereby driving the rotation of the fan blade (403). The rotation of the fan blade (403) attracts the smoke generated during the cutting of the cutting torch (305), so as to centrally collect and filter the smoke. When the second half gear (706) meshes with the first driven gear (204), the first half gear (703) does not mesh with the third driven gear (702), so that the second worm (612) remains stationary. The stationary state of the second worm (612) keeps the driving roller (609) stationary, and at the same time keeps the placement rack (602) stationary, facilitating the cutting of the steel by the cutting torch (305). After the linkage frame (202) moves back and forth along the reciprocating screw rod (201), the cutting torch (305) moves away from the inside of the placement rack (602). When the second half gear (706) separates from the teeth of the first driven gear (204), at the same time, the first half gear (703) meshes with the third driven gear (702). When the rotation of the third driven gear (702) drives the connecting rod (701) to rotate, the rotation of the connecting rod (701) drives the synchronous rotation of the third bevel gear (704). The rotation of the third bevel gear (704) and the rotation of the fourth bevel gear (705). The rotation of the fourth bevel gear (705) drives the rotation of the second worm (612). The rotation of the second worm (612) drives the rotation of the second worm gear (611). The rotation of the second worm gear (611) drives the rotation of the short shaft (608), and at the same time drives the rotation of the two driving rollers (609). The rotation of the driving rollers (609) drives the rotation of the placement rack (602). The rotation of the placement rack (602) turns over the steel placed inside. After the placement rack (602) finishes turning over, the first half gear (703) separates from the teeth of the third driven gear (702), so that the second worm (612) remains stationary. At the same time, the second half gear (706) meshes with the first driven gear (204) again for transmission, thereby driving the rotation of the reciprocating screw rod (201). The rotation of the reciprocating screw rod (201) drives the linkage frame (202) to reciprocate along the guide rod (203) again, so as to perform cutting on the steel after turning it over.
