Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plasma cutting, in particular to a plasma cutting device for port machinery steel plate. BACKGROUND

[0002] Plasma cutting technology is one of the core processes for port machinery steel plate processing. This technology forms tens of thousands of degrees of plasma arc through high-frequency arc ionization of gas, instantaneously melts the steel plate and blows away the slag, and the cutting speed can reach 3-5 times that of flame cutting. In the manufacturing of heavy equipment such as port cranes and gantry cranes, plasma cutting can precisely process thick steel plates.

[0003] Chinese patent CN110181155A discloses a plasma cutting device, which comprises a support frame, a driving assembly, a driven assembly and a passive assembly are arranged on the support frame; the driving assembly drives the driven assembly to rotate synchronously, and the driven assembly is provided with a plasma cutting head at the bottom; the driving assembly drives the passive assembly to rotate intermittently, and the passive assembly is provided with a rope, which is connected to the top of the plasma cutting head after passing through the driven assembly.

[0004] Chinese patent CN107052546A discloses a plasma cutting platform, which comprises a water tank for containing water, a grid placed above the water tank, and an air suction pipe arranged on one side of the water tank. The grid comprises a plurality of mutually spaced support plates, which are arranged vertically to the water surface in the water tank. The water surface is below the lower surface of the support plates and above the upper surface of the support plates. The air suction pipe is in communication with the gap between the adjacent two support plates. The adjacent two support plates and the water surface form a closed space, and the air suction pipe sucks the smoke and dust from the closed space, so that the smoke and dust generated during cutting operation cannot move around, thereby achieving good smoke removal effect.

[0005] The above-mentioned patents and prior art have the following problems:

[0006] When the steel plate is plasma cut, if a narrower steel strip needs to be cut from the edge of the steel plate, and the width of the steel strip is less than the gap between the plate-shaped support pieces of the cutting platform, the steel strip cannot be effectively supported during the cutting process. When the cutting process reaches a certain degree, the partially separated steel strip will start to fall due to its own gravity, and will generate a pulling force on the part of the mother plate that has not been cut off. The pulling of the falling steel strip will cause the cutting path to deviate, the cut will be uneven and the size will be inaccurate, and even a tear will be formed at the end instead of a smooth cut. The movement of the steel strip may cause the distance between the cutting torch and the steel plate to change, affecting the stability of the plasma cutting. SUMMARY

The surface of the driven plate 202 is provided with a driven wheel 2021. The advancing wheel 2012 and the driven wheel 2021 are movably connected with the surface of the advancing rail 103. The bottom of the driving plate 201 and the driven plate 202 is fixedly connected with a trigger block 203. The surface of the driving plate 201 and the driven plate 202 is movably connected with a moving plate 2014. The moving plate 2014 is fixedly connected with the side of a rail plate 2015.

[0070] The advancing driving source 2011 and the transverse moving driving source 2051 are preferably servo motors, and are controlled by a PLC and an encoder.

[0071] Operation process:

[0072] When the steel plate to be cut is placed on the surface of the support plate 1042, the support plate 1042 supports the steel plate, and the forward driving source 2011 is started to drive the surface pulley of the output shaft of the forward driving source 2011 through the transmission member one 2013 to rotate the pulley on the side of the forward wheel 2012, so that the forward wheel 2012 rotates and moves on the surface of the forward track 103. When the forward wheel 2012 moves the transverse track 204 to the preset cutting position through the forward track 103, the transverse driving source 2051 is started to drive the surface pulley of the output shaft of the transverse driving source 2051 through the transmission member two 2054 to rotate the pulley on the surface of the transverse wheel 2053, so that the pulley on the surface of the transverse wheel 2053 drives the transverse wheel 2053 to move on the surface of the transverse track 204. When the transverse wheel 2053 drives the transverse plate 205 to move on the surface of the transverse track 204, the cutting head 20521 on the surface of the transverse plate 205 is started to spray high-temperature plasma arc, so that the cutting head 20521 cuts the steel plate.

[0073] When the steel plate is placed on the surfaces of the plurality of support plates 1042, the steel plate presses down the support plates 1042 to move downward, so that the plurality of support plates 1042 are supported by the elastic support members 1041 at the bottoms thereof, and the support plates 1042 can be closely attached to different positions of the steel plate. In particular, when the steel plate itself is uneven, the elastic support members 1041 push the support plates 1042 to attach to the uneven surface of the steel plate, so as to reduce the suspension or warping of the plate before cutting. In order to make the supporting forces of the plurality of support plates 1042 consistent, the elastic support members 1041 at the bottoms of the support plates 1042 are selected to be springs of uniform specifications or springs with dampers, or air springs. The air springs at the bottoms of the support plates 1042 are externally connected to independent air pipes, and electromagnetic valves and pressure sensors are arranged between the air pipes and the air springs. The external air pipes are detected by the pressure sensors, so that when each air spring pushes the support plate 1042 at the top thereof to contact the steel plate with the same internal pressure, or the pressure sensors are installed on the contact surface between the support plate 1042 and the steel plate, the contact pressure between the support plate 1042 and the steel plate is consistent. When the contact pressure is insufficient or excessive, air is filled into the air pipe or air in the air spring is extracted. When the air pressure adjustment is completed, the electromagnetic valves between the air pipes and the air springs are closed, so that the support plates 1042 can stably support the steel plate, and the plurality of support plates 1042 can independently move upward and downward, thereby providing a retreat space for the movement of the isolation plate 20634 and the inner sleeve bottom rod one 20631.

[0074] When the forward driving source 2011 drives the forward wheel 2012 to move on the surface of the forward track 103, the trigger block 203 will be in contact with the rolling wheel 1044, and then the arc segment 2031 at the front end of the trigger block 203 will gradually contact the rolling wheel 1044, so that the rolling wheel 1044 moves along the arc segment 2031 to the bottom of the pressing segment 2032, thereby the rolling wheel 1044, the folding rod 1043 and the support plate 1042 are pushed to move downward by the height of the arc segment 2031 descending along the pressing segment 2032, and then when the cutting head 20521 on the surface of the transverse plate 205 is driven by the forward wheel 2012 to move to the preset position, the trigger block 203 at the side of the transverse track 204 has previously pressed the support plate 1042 at the bottom of the transverse track 204 before the transverse plate 205 moves in front of the support plate 1042, so that the space at the bottom of the support plate 1042 is released, thereby creating a moving space for the cutting head 20521 to move through the transverse plate 205 to drive the driving support plate 206 and the driven support plate 207 to move downward on the top of the support plate 1042.

[0075] It should be noted that the connection position of the arc segment 2031 and the pressing segment 2032 at the front end of the side of the isolation plate 20634 and the secondary bottom support plate 20734 is set in advance, that is, the connection position of the arc segment 2031 and the pressing segment 2032 at the front end of the side of the isolation plate 20634 and the secondary bottom support plate 20734 will be in contact with the rolling wheel 1044 at the side of the support plate 1042 at the bottom of the preset position in advance, and then the isolation plate 20634 and the secondary bottom support plate 20734 will move to the preset position with the forward wheel 2012 after the rolling wheel 1044 drives the support plate 1042 to be pressed and maintained on the pressing segment 2032. It should be noted that by designing a unified elastic support 1041 which is preferably a spring, the rolling wheel 1044 corresponds to the arc segment 2031 after the plate is pressed on the support plate 1042, of course, when the elastic support 1041 is preferably an air pipe, a valve and an air spring controlled by a pressure sensor, then the independent air spring can maintain the height of the support plate 1042 relatively consistent under the condition that the valve is inflated and the pressure is detected, so that the rolling wheel 1044 corresponds to the height of the arc segment 2031, thereby facilitating the arc segment 2031 to move, extrude and push the rolling wheel 1044, the folding rod 1043 and the support plate 1042 to move downward, and then when the trigger block 203 gradually moves away from the pressed support plate 1042, the elastic support 1041 restores to drive the support plate 1042 to reset, so that the rolling wheel 1044 at the top of the support plate 1042 is lifted and reset along the arc segment 2031 on the other side.

[0076] When the support plate 1042 at the bottom of the transverse plate 205 is pressed down, the transverse drive source 2051 is started, and the transverse drive source 2051 drives the transverse plate 205 to move horizontally on the top of the steel plate through the transverse wheel 2053, so that the cutting head 20521 at the side of the transverse plate 205 cuts the steel plate. Before the cutting head 20521 cuts, the isolation plate 20634 is partially located at the bottom of the steel plate, and the inner sleeve bottom rod one 20631 and the first polishing layer 20632 are also located outside the steel plate. At this time, the inner sleeve bottom rod one 20631 and the cutting seam cut by the cutting head 20521 are collinear, and then with the movement of the cutting head 20521, the movable plate 2052 will pull the sleeve plate one 2062, so that the sleeve plate one 2062 drives the first lifting rod 2063 and the first descending rod 2064 to move through the clamping strip one 20621, so that the first descending rod 2064 moves inside the moving clamping groove 20151 through the top protrusion, and the movement of the sleeve plate one 2062 will also pull the top to move on the top of the transverse rail 204 through the active support moving plate 206 and the linkage wheel one 2061. With the movement of the transverse plate 205, the inner sleeve bottom rod one 20631 and the first polishing layer 20632 which are narrower than the width of the cutting seam will be inserted into the inside of the cutting seam, that is, the width of the inner sleeve bottom rod one 20631 and the first polishing layer 20632 is narrower than the width of the cutting seam, and with the cutting movement of the cutting head 20521 on the surface of the transverse plate 205, the isolation plate 20634 is always located at the bottom of the cutting head 20521. At this time, the support plate 1042 at the bottom of the isolation plate 20634 has completed the descent, which facilitates the movement of the isolation plate 20634, so that the molten slag generated by the cutting of the cutting head 20521 will fall into the inside of the isolation plate 20634, thereby reducing the molten slag generated by the cutting falling into the inside of the support plate 1042 and the support cutting table 1, thereby improving the cutting cleanliness of the equipment and reducing the problem of slag hanging on the surface of the equipment affecting the service life of the equipment.

[0077] When the cutting head 20521 cuts to form a cutting seam, the movement of the cutting head 20521 will cause the inner sleeve bottom rod one 20631 and the first polishing layer 20632 to be inserted into the cutting seam, so that the inner sleeve bottom rod one 20631 and the first polishing layer 20632 are located inside the cutting seam to reduce the collapse of the plate on both sides of the cutting seam into the cutting seam, thereby deforming the cutting seam by pulling force, thereby affecting the part of the cutting seam that has not been cut by the cutting head 20521, causing the surface of the part to be cut to be rough, and when the inner sleeve bottom rod one 20631 and the first polishing layer 20632 are inserted into the cutting seam, the upper and lower pushing source 2055 at the top of the track plate 2015 is started, causing the upper and lower pushing source 2055 to push the track plate 2015, the first descending rod 2064 and the second descending rod 2074 downward, and in the process of the first descending rod 2064 moving downward, the teeth on the side of the first descending rod 2064 will drive the transmission wheel one 20622 to rotate, causing the transmission wheel one 20622 to rotate and drive the toothed plate on the surface of the first lifting rod 2063 to move upward, thereby causing the first descending rod 2064 to move downward and the first lifting rod 2063 to move upward, i.e. the first descending rod 2064 and the first lifting rod 2063 move inward, and the downward movement of the second descending rod 2074 will also drive the transmission wheel two 20722 to rotate through the teeth on the side of the second descending rod 2074, and through the transmission of the transmission wheel two 20722, thereby causing the second lifting rod 2073 and the second lifting rod 2073 on the surface of the second lifting rod 2073 to move downward synchronously, thereby causing the second descending rod 2074 and the second lifting rod 2073 to move in opposite directions;

[0078] In the opposite movement of the first lifting rod 2063 and the first lowering rod 2064, the bottom of the first lifting rod 2063 is attached to the two sides of the bottom of the steel plate cutting seam through the first bottom support plate 20633 connected by the inner sleeve bottom rod one 20631, so that the first bottom support plate 20633 supports the steel plate on both sides of the cutting seam, and the upward movement of the first lifting rod 2063 also synchronously moves the first lowering rod 2064 downward, so that the inner sleeve bottom rod two 20641 and the clamping plate one 20642 at the bottom of the first lowering rod 2064 are synchronously moved downward, and the clamping plate one 20642 moves downward along the inner sleeve bottom rod one 20631 and the surface of the first polishing layer 20632 through the bayonet 20643, so that the guide wheel one 20645 at the bottom of the first pressing plate 20644 abuts against the surface of the steel plate, and the wiping block one 20646 contacts the edge of the weld seam of the steel plate, and after the guide wheel one 20645 and the first bottom support plate 20633 contact the top and bottom of the steel plate respectively, the upper and lower sides of the steel plate are limited, reducing the outward expansion and falling of the steel plate, thereby reducing the pulling of the falling steel bar on the cutting seam, thereby reducing the unevenness of the surface of the subsequent cutting seam caused by the additional pulling force, and with the opposite movement of the first lowering rod 2064 and the first lifting rod 2063, the wiping block one 20646 abuts against the top surface of the steel plate, and the spade head 20635 abuts against the bottom surface of the steel plate, so that the top surface of the steel plate is scraped by the wiping block one 20646 during the movement of the first lifting rod 2063 and the first lowering rod 2064 with the cutting head 20521, reducing the adhesion of the molten slag splashed during cutting on the top surface of the steel plate on the side of the cutting seam, and the spade head 20635 arranged on the bottom surface of the steel plate is scraped off when the cutting head 20521 cuts the cutting seam of the steel plate, and the molten pool tumor is scraped off and falls into the inside of the isolation plate 20634, and during the process, the cutting moves to maintain the steel plates on both sides of the cutting seam without inward and outward deviation, and the cleaning of the cutting residues on the top and bottom surfaces of the steel plate is completed.

[0079] And the second descending rod 2074 and the second lifting rod 2073 to the opposite movement, the second lifting rod 2073 bottom of the second bottom support plate 20734 and the steel plate cutting seam on both sides of the bottom contact, and the second descending rod 2074 bottom of the scraping block 20744 and the guide wheel 20746 will be in contact with the top of both sides of the steel plate cutting seam, and then with the cutting head 20521 driven by the first descending rod 2064 and the first lifting rod 2063 movement, the stretching rope 2081 inside the side of the winding cavity 208 is gradually pulled, when the stretching rope 2081 is straightened, the second descending rod 2074 and the second lifting rod 2073 on the side of the first descending rod 2064 are pulled, the second descending rod 2074 and the second lifting rod 2073 move on the surface of the horizontal moving track 204 through the side of the driven support plate 207 of the top of the linkage wheel 2071, the inner sleeve bottom rod three 20732 and the second polishing layer 20733 which are narrower than the width of the cutting seam are inserted into the inside of the cutting seam, that is, the width of the inner sleeve bottom rod three 20732 and the second polishing layer 20733 is less than the width of the cutting seam, and moves with the cutting head 20521, the stretching rope 2081 between the subsequent adjacent sleeve plate two 2072 is straightened in turn, the second descending rod 2074 and the second lifting rod 2073 on the side of the first descending rod 2064 are pulled in turn, the inner sleeve bottom rod three 20732 inside is inserted into the inside of the cutting seam in turn, and then the inner sleeve bottom rod one 20631 and the inner sleeve bottom rod three 20732 are inserted into the inside of the cutting seam, and the second bottom support plate 20734 is supported at the bottom of the steel plate cutting seam, the guide wheel two 20746 and the scraping block two 20744 are pressed on the top of the steel plate cutting seam, so that the cutting head 20521 is cut, the cutting seam is segmented supported and limited, the small steel bar falling away from the cutting process is reduced, especially when cutting the small steel bar on the surface of the steel plate, the falling and pulling of the uncut cutting seam caused by the lack of support of the plate-shaped object 1042;

[0080] In order to make the space between the guide wheel two 20746, the scraping block two 20744 and the secondary bottom support plate 20734 and the thickness of the steel plate consistent after the opposite movement, and make the guide wheel two 20746, the scraping block two 20744 wrap the high-temperature-resistant elastic rubber layer, or install a spring between the guide wheel two 20746 and the secondary bottom support plate 20745, so that the space between the guide wheel two 20746, the scraping block two 20744 and the secondary bottom support plate 20734 can be moved and connected to the surface of the steel plate, and the inner sleeve bottom rod four 20742 can be pulled out from the inside of the secondary descending rod 2074 and fixed by the bolts on the surface of the secondary descending rod 2074, and the connection mode between the secondary lifting rod 2073 and the inner sleeve bottom rod three 20732, the primary descending rod 2064 and the inner sleeve bottom rod two 20641, and the primary lifting rod 2063 and the inner sleeve bottom rod one 20631 is the same as the connection mode between the secondary descending rod 2074 and the inner sleeve bottom rod four 20742, so that the space between the guide wheel one 20645 and the primary bottom support plate 20633 and the space between the guide wheel two 20746 and the secondary bottom support plate 20734 can be adjusted, so as to adapt to steel plates of different thicknesses;

[0081] When the cutting head 20521 finishes cutting the steel plate, the advancing drive source 2011 drives the advancing wheel 2012 to approach the surface of the steel plate, and the primary polishing layer 20632 and the secondary polishing layer 20733 on the side of the transverse moving rail 204 contact the cutting surface of the steel plate that needs to be polished. At this time, the guide wheel two 20746 and the guide wheel one 20645 are preferably universal ball head wheels or universal wheels, so that during the movement of the transverse moving rail 204, the steel plate is always limited between the guide wheel two 20746 and the secondary bottom support plate 20734 and the primary bottom support plate 20633 and the guide wheel one 20645, thereby reducing the process of polishing alignment. When the primary polishing layer 20632 and the secondary polishing layer 20733 contact the cutting surface of the steel plate that needs to be polished, the transverse plate 205 is reset under the drive of the transverse wheel 2053, and the primary polishing layer 20632 and the secondary polishing layer 20733 move and polish the cutting surface of the steel plate during the process of the transverse plate 205 returning to the original position, so that the upper and lower parts of the cutting surface of the steel plate and the cutting surface are processed and flattened by the scraping block one 20646, the isolation plate 20634 and the primary polishing layer 20632 and the secondary polishing layer 20733 in turn.
