[0002] Steel plates are widely used in the manufacture of metal structural components and mechanical parts, and are used in fields such as construction engineering, shipbuilding, automotive industry, pressure vessels and heavy machinery. In order to meet the dimensional accuracy and shape requirements of different structural components, steel plates usually need to be cut before they are put into use to obtain steel plate workpieces that meet the size and shape requirements.

[0003] A search revealed that the invention patent with publication number CN110666366A discloses a laser cutting machine for steel plate processing. It uses an air purifier to purify odorous gases, thereby completely removing particulate matter from the gas and preventing it from entering the air purifier and causing blockages. This ensures that the air purifier can continuously and normally purify the gas, effectively preventing the spread of odorous gases.

[0004] Existing steel plate cutting equipment often suffers from concentrated heat and uneven cooling during the cutting process, resulting in a large heat-affected zone that can easily cause changes in the steel plate's microstructure and cut deformation. Simultaneously, molten slag and debris within the cutting kerf are difficult to clean promptly, often adhering to the cut edges or accumulating on the cutting table, affecting cutting quality and increasing the subsequent cleaning burden. Furthermore, it largely relies on manual feeding in conjunction with the cutter, which is labor-intensive and prone to uneven feeding and positioning deviations, thus affecting cutting accuracy. Summary of the Invention

[0008] A further technical improvement of the present invention is that the magnetic suction unit includes two adsorption rollers that are rotatably disposed inside the cutting table and located directly below the cutting groove, and the two adsorption rollers rotate synchronously in different directions; Each of the adsorption rollers has a chip discharge port on one side of its top. A water collection tank is provided below the two adsorption rollers.

[0009] A further technical improvement of the present invention is that: the pressing unit includes a pressure roller frame, the upper part of the pressure roller frame is a buffer frame, and the bottom of the buffer frame is rotatably mounted with a pressure roller; A connecting plate is installed on the top of the buffer frame. The lower surface of the connecting plate is fixed to the sealing cover, and an electric push rod is installed on the middle surface of the connecting plate.

[0010] A further technical improvement of the present invention is that the transfer and loading unit includes a lifting transmission component disposed within the edge of the cutting table; The bottom of the lifting transmission component is fitted with a reciprocating rotating pusher; The pusher includes a cam that is synchronously driven by two drive shafts, which are connected by a synchronous belt.

[0011] A further technical improvement of the present invention is that: the lifting transmission component includes a support plate embedded in the cutting table and not communicating with the cutting groove, and a movable seat that is in contact with the cam is provided below the support plate, and a spring is sleeved on the outside of the movable seat; Several rotating wheels are installed on the upper surface of the bearing plate; Initially, the intermediate roller is at the same height as the conveyor belt, and a fixed baffle blocks one side of the steel plate. During descent, the central roller descends and extends into the interior of the cutting table, where the bottom of the steel plate is supported by the cutting table.

[0012] A further technical improvement of the present invention is that: the outer edge of the conveyor belt is provided with an adjustment plate pushed by a synchronous electric push rod; The end of the adjusting plate extends into the interior of the cutting chamber, and the bottom surface of the adjusting plate is in contact with the upper surface of the central rotating wheel at the initial height.

[0013] A further technical improvement of the present invention is that: the bottom surface of the fixed baffle and the upper surface of the cutting table are provided with a discharge channel for steel plate discharge, and the height of the discharge channel is greater than the thickness of the steel plate.

[0014] A further technical improvement of the present invention is that: the sliding pusher unit includes an electric push rod installed on the inner wall of the cutting chamber, the pushing end of the electric push rod is equipped with a sleeve frame, the inside of the sleeve frame is provided with a push plate that moves in the vertical direction, the outer surface of the push plate that extends into the sleeve frame is sleeved with a spring, and the bottom of the push plate is provided with a positioning recess that contacts the side of the steel plate. The top of the inner cavity of the cutting chamber is provided with a pusher platform that works in conjunction with the pusher plate.

[0015] A further technical improvement of the present invention is that the pushing platform includes an inclined section and a straight section; The inclined section slides against one side surface of the push plate, and the straight section slides against the upper surface of the push plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a holding unit and a cleaning and cooling unit, before cutting, the holding unit holds both sides of the steel plate cutting area, cutting the two sides of the steel plate first and then the middle area, reducing the heat concentration in a single cutting area, which helps the water mist cooling to act evenly on the cut, further reducing the heat-affected zone. During the cutting process, high-pressure airflow is continuously sprayed out from the air outlet to blow away the slag and waste in the cutting kerf. The rotating cleaning blocks one and two rotate synchronously under the meshing of gears, working together to sweep the cutting waste splashed on both sides into the cutting groove, realizing the combined effect of airflow blowing and mechanical cleaning. The waste generated during the cutting process mixes with the cooling water mist and enters the magnetic adsorption unit inside the cutting table, using the magnetic adsorption principle to effectively separate and collect the metal particles in the waste mixture. 2. By setting a fixed baffle and a transfer feeding unit, initially, the height of the transfer wheel is consistent with that of the conveyor belt. When the steel plate is conveyed to the edge of the cutting table, the fixed baffle positions and blocks one side of the steel plate. At this time, the transfer wheel can support the steel plate and ensure its smooth transition. Subsequently, under the rotation of the cam, the movable seat drives the bearing plate to descend, and the transfer wheel moves down and extends into the cutting table, so that the steel plate is finally supported by the table surface of the cutting table, thereby completing the stable placement of the steel plate and the positioning before cutting. 3. By setting up a sliding pusher unit, after one side of the steel plate is limited by a fixed baffle, the electric pusher drives the sleeve frame to push horizontally, causing the pusher plate to slide along the inclined section of the pusher table. During the sliding, the pusher plate is pushed down and approaches the other side of the steel plate. When the pusher plate slides to the straight section of the pusher table, the positioning recess fits tightly with the side of the steel plate. When sliding along the straight section, the positioning recess provides limiting support for the other side of the steel plate, keeping the conveying position of the steel plate always at the preset position, thus improving the conveying and cutting accuracy.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0021] Please see Figures 1-6 As shown, the present invention provides a cutting device for steel plate processing, including a cutting chamber 1, a conveyor belt 3 for directional conveying of steel plates on one side of the cutting chamber 1, and a cutting table 5 for supporting the bottom of the steel plate at the bottom of the inner cavity of the cutting chamber 1. A transfer loading unit is provided at the edge of the cutting table 5, and a strip-shaped cutting groove 26 is provided on the upper surface of the cutting table 5. A fixed baffle 6 is fixedly provided on one side of the inner cavity of the cutting chamber 1 to limit the steel plate on one side, and a cutting assembly for segmented cutting of the steel plate is raised and lowered on the top of the inner cavity of the cutting chamber 1 near the fixed baffle 6. The cutting assembly includes a sealing cover 16 located directly above the cutting groove 26, the bottom of which is in close contact with the upper surface of the steel plate; The top of the inner cavity of the sealing cover 16 is provided with a cutter 20 that moves longitudinally, and the interior of the sealing cover 16 is provided with several atomizing nozzles 19 for spraying water mist to cool down. Both sides of the sealing cover 16 are provided with pressing units to fix the cutting area, and the bottom surface of the cutter 20 is equipped with a cleaning and cooling unit. The cleaning and cooling unit includes a base plate 21. The middle surface of the base plate 21 is provided with an air outlet 30 that sprays out high-pressure airflow and blows the waste chips away from the cutting seam. The bottom surface of the base plate 21 is respectively rotatably equipped with a cleaning block 17 and a cleaning block 28 that sweep the cutting waste chips splashed on both sides toward the cutting groove 26. The cleaning block 17 and the cleaning block 28 rotate synchronously toward or away from each other through meshing gears. The air outlet 30 is connected to the air outlet end of the sealing cover 16 via a flexible hose; The cutting table 5 is equipped with a magnetic suction unit for separating the waste chip mixture; The inner cavity of the cutting chamber 1 is provided with a sliding pusher unit that limits the other side of the steel plate on the side away from the fixed baffle 6.

[0022] During steel plate processing, the transfer and feeding unit is at the same height as the conveyor belt 3. The steel plate is directionally conveyed by the conveyor belt 3 to the transfer and feeding unit inside the cutting chamber 1. The fixed baffle 6 limits one side of the steel plate, while the sliding pusher unit adjusts and limits the other side, thereby achieving stable positioning of the steel plate during the cutting process. Subsequently, the transfer and feeding unit lowers its height and places the steel plate on the cutting table 5, ensuring that the steel plate is accurately positioned in the cutting groove 26. The strip-shaped cutting groove 26 provides space for the cut during the cutting process, so that the cutter 20 can smoothly penetrate the steel plate, realizing automatic conveying and positioning of the steel plate, reducing manual intervention and improving processing efficiency. After the steel plate enters the cutting position, the sealing cover 16 descends and fits tightly against the upper surface of the steel plate, forming a closed cutting space.

[0023] At this time, the cutter 20 inside the sealing cover 16 moves longitudinally and cuts in segments, first cutting the two sides of the steel plate and then the middle area. This reduces the heat concentration in a single cutting area and helps the water mist to cool the cut evenly, further reducing the heat-affected zone. During the cutting process, the atomizing nozzle 19 continuously sprays fine water mist to cool the cutting area in real time, suppressing heat diffusion and reducing the heat-affected zone. The air outlet 30 continuously sprays high-pressure air to blow away the slag and debris in the cutting seam. The rotating cleaning blocks 17 and 2 18 rotate synchronously under the meshing of gears, working together to sweep the cutting debris splashed on both sides into the cutting groove 26, realizing the combined effect of airflow purging and mechanical cleaning. The debris generated during the cutting process mixes with the cooling water mist and enters the magnetic adsorption unit inside the cutting table 5. The magnetic adsorption principle is used to effectively separate and collect the metal particles in the debris mixture.

[0024] See Figure 6 As shown, the magnetic suction unit includes two adsorption rollers 27 that are rotatably disposed inside the cutting table 5 and located directly below the cutting groove 26. The two adsorption rollers 27 rotate synchronously in different directions. Each adsorption roller 27 has a chip discharge port 29 on one side of its top. A water collection trough 28 is provided below the two adsorption rollers 27; The waste chip mixture falling into the cutting groove 26 will first come into contact with two adsorption rollers 27. The surface of the adsorption rollers 27 is magnetic, which can magnetically adsorb the ferromagnetic metal particles in the mixture. The two adsorption rollers 27 rotate synchronously in opposite directions, so that the waste chip particles are driven to the chip discharge port 29 on their surface, and the waste chips are automatically discharged through the chip discharge port 29.

[0025] The cooling water in the mixture falls into the water collection tank 28 under gravity. After sedimentation and filtration, it can be recycled, thereby achieving solid-liquid separation and resource recovery.

[0026] See Figure 4 As shown, the pressing unit includes a pressure roller frame 15, the upper part of which is a buffer frame, and the bottom of the buffer frame is rotatably mounted with a pressure roller. A connecting plate 14 is installed on the top of the buffer frame. The lower surface of the connecting plate 14 is fixed to the sealing cover 16, and an electric push rod 13 is installed on the middle surface of the connecting plate 14. The cutting assembly is lowered by the electric push rod 213, at which time the holding unit holds both sides of the steel plate cutting area; This ensures the steel plate is firmly held during the cutting process, preventing positional shifts due to vibration or stress release; at the same time, the buffer frame can act as a buffer under stress, ensuring that the force exerted by the pressure roller on the steel plate remains stable and controllable.

[0027] See Figure 5 As shown, the transfer and loading unit includes a lifting transmission component located within the edge of the cutting table 5; The bottom of the lifting transmission component is fitted with a reciprocating rotating pusher; The pushing component includes a cam 23 that is synchronously driven by two drive shafts, which are driven by a synchronous belt.

[0028] During operation, the rotation of cam 23 pushes the lifting transmission component to rise and maintains the same height as the conveyor belt 3, so that the pushing component can contact the edge of the steel plate to be loaded. After the steel plate is positioned, the cam 23 reciprocates as the transmission shaft drives it, and the lifting transmission component descends, smoothly lowering the steel plate to the cutting position of the cutting table 5; the synchronous belt ensures that the two transmission shafts move in unison, so that the cam 23 always remains coordinated.

[0029] See Figure 5 As shown, the lifting transmission component includes a support plate 22 embedded in the cutting table 5 and not communicating with the cutting groove 26. Below the support plate 22 is a movable seat 24 that pushes against the cam 23. A spring 25 is sleeved on the outside of the movable seat 24 to provide a restoring force. Several intermediate rotating wheels 4 are installed on the upper surface of the support plate 22; Initially, the intermediate wheel 4 is at the same height as the conveyor belt 3, and the fixed baffle 6 positions and blocks one side of the steel plate; During descent, the central rotating wheel 4 descends and extends into the interior of the cutting table 5, where the bottom of the steel plate is supported by the cutting table 5.

[0030] In the initial state, the height of the intermediate roller 4 is consistent with that of the conveyor belt 3. When the steel plate is conveyed to the edge of the cutting table 5, the fixed baffle 6 positions and blocks one side of the steel plate. At this time, the intermediate roller 4 can support the steel plate and ensure its smooth transition. Subsequently, under the rotation of the cam 23, the movable seat 24 drives the bearing plate 22 to descend, and the intermediate roller 4 moves down and extends into the cutting table 5, so that the steel plate is finally supported by the table surface of the cutting table 5, thereby completing the stable placement of the steel plate and the positioning before cutting.

[0031] See Figure 1 As shown, the outer edge of the conveyor belt 3 is provided with an adjustment plate 2 that is driven by a synchronous electric push rod; The end of the adjusting plate 2 extends into the interior of the cutting chamber 1, and the bottom surface of the adjusting plate 2 is in contact with the upper surface of the central rotating wheel 4 at the initial height; During the steel plate conveying process, the adjusting plate 2 can be finely adjusted along the width direction of the steel plate under the drive of the synchronous electric push rod, so as to correct the steel plate along the conveying direction and make it accurately aligned with the center line of the cutting groove 26.

[0032] See Figure 2 As shown, the bottom surface of the fixed baffle 6 and the upper surface of the cutting table 5 are provided with a discharge channel for steel plate discharge, and the height of the discharge channel is greater than the thickness of the steel plate. When the steel plate is being conveyed, the central roller 4 is at the same height as the conveyor belt 3, and the fixed baffle 6 positions the steel plate on one side; when cutting, the central roller 4 drives the steel plate to descend, so that the steel plate falls on the cutting table 5; After the steel plate is cut, the cam 23 continues to rotate, exposing the central rotating wheel 4 on the surface of the cutting table 5, and driving the cut workpiece to be smoothly discharged through the unloading channel. Since the height of the unloading channel is greater than the thickness of the steel plate, the steel plate will not get stuck when passing through, and automatic unloading or manual guided unloading can be achieved.

[0033] See Figure 2 and Figure 3 As shown, the sliding pusher unit includes an electric push rod 8 installed on the inner wall of the cutting chamber 1. The push end of the electric push rod 8 is equipped with a sleeve 9. The inside of the sleeve 9 is provided with a push plate 10 that moves in the vertical direction. The outer surface of the push plate 10 that extends into the sleeve 9 is fitted with a spring 12. The bottom of the push plate 10 is provided with a positioning recess 11 that contacts the side of the steel plate. The top of the inner cavity of the cutting chamber 1 is provided with a pusher 7 that works in conjunction with the pusher plate 10; The push platform 7 includes an inclined section and a straight section; The inclined section slides against one side surface of the push plate 10, and the straight section slides against the upper surface of the push plate 10.

[0034] After one side of the steel plate is limited by the fixed baffle 6, the electric push rod 8 drives the sleeve 9 to push horizontally, causing the push plate 10 to slide along the inclined section of the push platform 7. During the sliding, the push plate 10 is pushed down and approaches the other side of the steel plate. When the push plate 10 slides to the straight section of the push platform 7, the positioning recess 11 fits tightly with the side of the steel plate. When sliding along the straight section, the positioning recess 11 provides limiting support for the other side of the steel plate, keeping the conveying position of the steel plate always at the preset position, thus improving the conveying and cutting accuracy. After the steel plate is positioned, the electric push rod 8 retracts in the opposite direction, and the push plate 10 is reset under the action of the spring 12, so that the push plate 10 returns to the initial height.

[0035] In use, this invention employs a holding unit and a cleaning and cooling unit. Before cutting, the holding unit holds both sides of the steel plate cutting area, cutting the sides of the steel plate first and then the middle area. This reduces the heat concentration in a single cutting area and helps the water mist cooling evenly act on the cut, further reducing the heat-affected zone. During the cutting process, high-pressure airflow is continuously sprayed from the air outlet 30 to blow away the slag and debris in the cutting kerf. The rotating cleaning blocks 17 and 28 rotate synchronously under the meshing of gears, working together to sweep the cutting debris splashed on both sides into the cutting groove 26, achieving a combined effect of airflow blowing and mechanical cleaning. The debris generated during the cutting process mixes with the cooling water mist and enters the magnetic adsorption unit inside the cutting table 5, using the magnetic adsorption principle to effectively separate and collect the metal particles in the debris mixture. By setting a fixed baffle 6 and a transfer feeding unit, initially, the height of the transfer wheel 4 is consistent with that of the conveyor belt 3. When the steel plate is conveyed to the edge of the cutting table 5, the fixed baffle 6 positions and blocks one side of the steel plate. At this time, the transfer wheel 4 can lift the steel plate and ensure its smooth transition. Subsequently, under the rotation of the cam 23, the movable seat 24 drives the bearing plate 22 to descend, and the transfer wheel 4 moves down and extends into the cutting table 5, so that the steel plate is finally supported by the table surface of the cutting table 5, thereby completing the stable placement of the steel plate and the positioning before cutting. By setting up a sliding pusher unit, after one side of the steel plate is limited by the fixed baffle 6, the electric push rod 8 drives the sleeve 9 to push horizontally, so that the pusher plate 10 slides along the inclined section of the pusher table 7. During the sliding, the pusher plate 10 is pushed down and approaches the other side of the steel plate. When the pusher plate 10 slides to the straight section of the pusher table 7, the positioning recess 11 fits tightly with the side of the steel plate. When sliding along the straight section, the positioning recess 11 provides limiting support for the other side of the steel plate, keeping the conveying position of the steel plate always at the preset position, thus improving the conveying and cutting accuracy.
