Description

Technical Field

[0001] The present application relates to the field of laser cutting technology, and in particular to a steel plate laser cutting device and cutting process. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize, ablate or reach ignition point rapidly, while using a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece.

[0003] At present, the existing steel plate laser cutting device, such as the patent with publication number CN210413098U, discloses a laser cutting machine for steel plate processing, including a longitudinal rod and a transverse rod. The bottom end of the workbench is connected to the top end of the frame through a transmission device. Two groups of columns are symmetrically arranged on the right part of the top end of the frame. A top plate is arranged on the top of the column. Support plates are arranged on the left and right ends of the frame respectively. A through hole is arranged on the top end of the support plate. The top end of the first motor is connected to the bottom end of the support plate, the top output end of the first motor is connected to the bottom input end of the first coupling, the top output end of the first coupling is connected to the bottom end of the first lead screw, the top end of the first lead screw is rotatably connected to the bottom end of the top plate, and the top end of the crossbeam is provided with a plurality of groups of threaded holes connected up and down. The threaded holes at the top end of the crossbeam are installed in coordination with the external threads of the first lead screw. The crossbeam can move up and down on the first lead screw, and the steel plate is automatically cut by the controller. It can automatically adapt to the shape of the steel plate and quickly fix the steel plate to be cut, thereby improving the stability of the steel plate during the steel plate cutting process.

[0004] With regard to the above-mentioned related technologies, the steel plates after being cut need to be collected by the staff themselves, which is time-consuming and laborious. The residues generated by the cutting cannot be cleaned up in time. Moreover, the residues at high temperatures have a certain degree of adhesion and are easy to adhere to the cutting place, making it difficult to clean after cooling down. Summary of the invention

[0005] In order to solve the above technical problems, the present application provides a steel plate laser cutting device and cutting process.

[0006] The present application provides a steel plate laser cutting device and cutting process, which adopts the following technical solutions: A steel plate laser cutting device comprises a support, a laser cutting part, a pushing part and a fixing part, wherein the fixing part and the laser cutting part are both arranged on the support, and the pushing part is arranged at one end of the support away from the laser cutting part. The support comprises a workbench and a tilting seat, and the laser cutting part is arranged on the workbench, and one end of the workbench is fixedly connected to the tilting seat. From the end close to the workbench to the direction gradually away from the workbench, the height of the top of the tilting seat becomes lower and lower, and the interior of the tilting seat is hollow, and an inclined plate is arranged at the end of the tilting seat close to the workbench, the inclination direction of the inclined plate is consistent with the inclination direction of the top of the tilting seat, and the inclination slope of the inclined plate is greater than the inclination slope of the top of the tilting seat, and an accommodating groove for accommodating the cut steel plate block is arranged at the end of the tilting seat away from the workbench, and a collecting groove is opened on the upper end surface of the workbench corresponding to the laser cutting part, and a collecting drawer is arranged at the vertical bottom of the workbench, and the collecting groove is connected with the collecting drawer.

[0007] By adopting the above technical solution, the steel plate blocks cut by the steel plate laser cutting device can be automatically stored in the receiving groove through the special setting in the tilting seat, without the need for manual collection and sorting, and without the need for other energy such as electric energy. The cut steel plate blocks can be transported and collected while the steel plates are being cut and transported. In addition, while the steel plates are being cut and transported, the cutting residues on the upper surface of the workbench can be cleaned in time, that is, the cutting residues on the upper surface of the workbench are cleaned by the relative movement friction of the lower surface of the steel plate on the upper surface of the workbench. The setting position of the collection groove and the collection drawer, as well as the design method and structure, can directly collect the residues synchronously while cutting. For the residues that have not fallen into the collection groove, that is, on the workbench, the residues that have been cleaned in time can also be collected during the transportation of the steel plate.

[0008] Optionally, the laser cutting part includes a support frame, a movable groove is provided on both sides of the workbench, a driving screw and a sliding rod are respectively connected to the two movable grooves, one end of the support frame is threadedly connected to the driving screw, and the other end is slidably connected to the sliding rod, one end of the driving screw is provided with a driving motor, the driving motor is located in the movable groove, the output shaft of the driving motor is coaxially and fixedly connected to the driving screw, a sliding groove is provided at the top of the support frame, the sliding groove is provided on a side of the support frame close to the tilting seat, a sliding screw is rotatably connected in the sliding groove, one end of the support frame is fixedly connected to the sliding motor, the output shaft of the sliding motor is coaxially and fixedly connected to the sliding screw, a sliding block is threadedly connected to the sliding screw, the sliding block is slidably connected to the support frame, the top of the sliding block is fixedly connected to a lifting cylinder, and the piston rod of the lifting cylinder passes through the sliding rod and is fixedly connected to a laser cutting head for cutting steel plates.

[0009] By adopting the above technical solution, the support frame can drive the laser cutting head to move quickly in the length direction of the workbench under the joint action of the driving screw, sliding rod and moving groove, that is, it can quickly adjust the cutting position of the laser cutting head on the steel plate. The conveying steel plate itself can adjust the cutting position. In conjunction with the adjustment of the position of the laser cutting head, the two-pronged approach can quickly adjust the relative position of the steel plate and the laser cutting head, shorten the adjustment time, and improve the adjustment efficiency. The laser cutting head also uses the lifting of the lifting cylinder to adjust the height distance from the steel plate surface, that is, to achieve adaptive adjustment of the cutting thickness of the steel plate.

[0010] Optionally, the fixing member includes a side panel, a fixed cylinder and a fixed plate. The two side panels are fixed in parallel and opposite to each other on the upper end surface of the workbench. A fixed cylinder is fixed on one side of the side panel, and a fixed plate is provided on the other side of the side panel. The fixed plate is arranged parallel to the side panel. The telescopic rod of the fixed cylinder passes through the side panel and is connected to the fixed plate. The two fixed plates can adjust the spacing under the telescopic action of their respective corresponding fixed cylinders.

[0011] By adopting the above technical solution, the fixing part itself can achieve a certain degree of fixation during the cutting process, and can also limit the moving direction of the steel plate during the conveying process. The cooperation between the fixed cylinder and the fixed plate can facilitate the loading of the steel plate and provide a relatively ample space for the loading of the steel plate. Secondly, it can quickly adapt to the cutting of steel plates of different widths by adjusting the spacing. During the cutting process, the steel plate can be further fixed by clamping the steel plate. That is, in the non-cutting state, the spacing of the fixed plates is slightly wider than the width of the steel plate, which is more of a limit to the movement of the steel plate. In the cutting state, the spacing of the fixed plates is in a state of clamping the steel plate. When the steel plate is loaded, the spacing of the fixed plates is at its widest. The convenience and efficiency of loading the steel plate are improved; the effect of cutting and conveying the steel plate on the workbench is guaranteed; during cutting, the steel plate is fixed.

[0012] Optionally, the pushing member includes a connecting block, a pushing plate, a pushing motor, a pushing screw and a pushing groove. A pushing groove is opened on the upper end surface of the workbench, and the pushing groove is extended along the length direction of the workbench. A pushing screw is arranged in the pushing groove. The end of the workbench away from the tilting seat is fixedly connected with the pushing motor, the connecting block is threadedly connected to the pushing screw, the pushing motor and the pushing screw are coaxially fixedly connected, a pushing plate is connected to the top of the connecting block, and the pushing motor and the pushing screw work together to drive the connecting block and the pushing plate to slide under the limit of the pushing groove. The pushing plate is arranged on the upper end surface of the workbench, and the length direction of the pushing plate is consistent with the width direction of the workbench.

[0013] By adopting the above technical solution, the push of the push plate on the workbench makes the pushing of the steel plate more stable. The combination of the push motor and the push screw provides a stable and steady pushing force for the push plate, pushing the steel plate to the laser cutting head on the workbench. The combination of the push plate, the push motor and the push screw provides conveying power when the steel plate needs to be conveyed, and provides a certain limit fixing effect when the steel plate is cut. It cooperates with the two fixed plates to form a fixed limit in three dimensions (the left and right sides of the steel plate plus one end) for the steel plate to better support the fixity and stability required for laser cutting. The coordinated limiting effect of the connecting block and the push groove can make the pushing trajectory of the push plate on the workbench smoother and the conveying direction of the steel plate more fixed. The length direction of the push plate is consistent with the width direction of the workbench in order to make the pushing force of the push plate on the steel plate more dispersed, that is, the thrust range of the steel plate is wider and the conveying movement is smoother.

[0014] Optionally, the connecting block is a hollow cavity, and the lower end surface of the pushing plate is fixedly connected to a connecting rod, the other end of the connecting rod is inserted into the connecting block, an operating groove is opened at the top of the pushing plate, and a connecting hole is opened inside the connecting rod, the operating groove, the connecting hole and the hollow cavity are connected to form a lifting channel, the diameter of the operating groove is larger than the diameter of the connecting hole, the diameter of the hollow cavity is larger than the diameter of the connecting hole, and a lifting piece is rotatably provided in the lifting channel, and the end of the pushing groove away from the support frame is connected to a placement groove for placing the push plate, and the push plate is located in the placement groove, and the lifting of the lifting piece drives the connecting rod to rise and fall in the hollow cavity, thereby driving the push plate to be higher than the top of the placement groove.

[0015] By adopting the above technical solution, in the initial state, the push plate is located in the placement slot, and the two clamping blocks are respectively located in the two lifting slots; when the steel plate needs to be pushed, the push plate is located above the placement slot, and the push plate slides on the upper surface of the workbench, and the two clamping blocks are respectively located in the two fixed slots. The function of the lifting member is to adjust the height position of the push plate and the connecting rod accordingly. During the loading of the steel plate, the workbench is purely flat, which is more conducive to loading and laying the steel plate flat on the workbench. When the flattened steel plate needs to be transported and moved on the workbench later, the height of the push plate is raised to be flush with the upper surface of the workbench, which can provide technical guarantee for the pushing movement of the push plate in the push slot, otherwise the pushing power of the push motor and the push screw will be hindered by the placement slot. The push plate is set in the placement slot. In addition to facilitating the laying of the steel plate on the workbench, it also has another function of facilitating the identification of whether there are foreign objects between the steel plate and the workbench, ensuring the flatness between the steel plate and the workbench, and also ensuring the cleanliness of the cutting residues of the workbench during the later steel plate transportation.

[0016] Optionally, the lifting member includes a rotating rod, a rotating plate and a clamping plate, the rotating rod is arranged in the connecting hole, the rotating plate is arranged in the operating groove, the clamping plate is arranged in the hollow cavity, one end of the rotating rod is fixedly connected to the rotating plate, the other end of the rotating rod is fixedly connected to the clamping plate, and clamping blocks are symmetrically extended along the edge of the clamping plate. A lifting groove for cooperating with the clamping block is opened at the bottom of the hollow cavity, and the top of the lifting groove is connected to a fixed groove for positioning the clamping block, and the rotation of the rotating plate drives the clamping block to enter the fixed groove.

[0017] By adopting the above technical solution, the lifting member specifically rotates the rotating rod through the rotation of the rotating plate, and then rotates the clamping plate, and screws the clamping block on the clamping plate into the fixed groove. The simple structural design realizes the flexible adjustment of the height position of the pushing plate.

[0018] Optionally, there are multiple collecting grooves on the upper end surface of the workbench, and the multiple collecting grooves are arranged in parallel. The length direction of the collecting grooves is consistent with the cutting direction of the laser cutting part. In the length direction of the workbench, the length of the multiple collecting grooves is greater than the length range of movement of the laser cutting part.

[0019] By adopting the above technical solution, the multiple settings of the collection grooves and the direction consistent with the cutting direction can better adapt to the cutting and collection needs of different positions, that is, the cutting of the laser cutting parts at different positions can have adjacent collection grooves to directly collect the cutting residues in the first time. The length of the multiple collection grooves is greater than the moving length range of the laser cutting parts. First, it is to meet the collection needs of each position while cutting, and further to effectively collect the scattered parts of the cutting, and further to completely clean the steel plate during pushing, especially the cleaning that needs to be completed by pushing the steel plate when the cutting is scattered on the workbench. The steel plate is pushed to the tilting seat, so it is possible to push the residues scattered from the workbench to a certain range into the tilting seat. The length of the collection grooves is set to be greater than the moving length range of the laser cutting parts, which can avoid the residues from being pushed into the tilting seat to a certain extent.

[0020] Optionally, a buffer plate is provided in the receiving groove of the tilting seat, the buffer plate is vertically arranged, a gap is provided between the buffer plate and the bottom surface of the receiving groove, the buffer plate is connected to the inner wall of the receiving groove through a plurality of rigid springs, and the plurality of rigid springs are evenly distributed.

[0021] By adopting the above technical solution, a gap is provided between the buffer plate and the bottom surface of the receiving groove, which can prevent the impact-resistant movement of the buffer plate from scratching the bottom surface of the receiving groove, and also prevent the bottom surface of the receiving groove from hindering the movement of the buffer plate. The buffer plate is fixed by a number of rigid springs and arranged vertically, so that the fixation and impact buffering of the buffer plate are both achieved by the rigid springs. Under the support and buffering action of the rigid springs, the buffer plate can better buffer the steel plate that dives down due to gravity. The evenly distributed rigid springs can also evenly disperse the impact force to ensure the overall good buffering effect of the buffer plate.

[0022] Optionally, a collecting plate is provided in the accommodating groove, and a collecting guide rail is provided at the bottom of the inclined plate. The collecting plate and the collecting guide rail are connected by a collecting rod. The length extension direction of the collecting guide rail is parallel to the width direction of the inclined plate. The collecting guide rail drives the collecting plate to slide in the width direction of the inclined plate. A discharge port is opened on the side wall on one side of the width direction of the inclined seat, and the discharge port matches the shape of the collecting plate.

[0023] By adopting the above technical solution, the collecting guide rail drives the collecting plate to slide in the width direction of the inclined plate, which has two main functions. One is to finally transport the steel plates that need to be discharged, that is, to push the steel plates to the discharge port. The second is to avoid the concentrated accumulation of steel plates, appropriately push and disperse the steel plates, and further avoid hindering the normal transportation of the steel plates after cutting.

[0024] A cutting process comprises the following steps: S1: Ensure that the push plate is in the placement slot, transport the steel plate to the workbench through the steel plate conveyor, and confirm that the end of the steel plate is completely transported to the workbench and the end of the steel plate has leaked out of the push plate; S2: Start the fixed cylinder, which drives the two fixed plates to move toward each other, fixing the position of the steel plate and limiting the conveying trajectory of the steel plate in the length direction of the workbench; S3: Pull out the rotating plate upwards to drive the pushing plate to rise, and then rise from the placement slot to be flush with the upper end surface of the workbench, rotate the rotating plate so that the clamping block enters the fixed slot to lock the height of the pushing plate; S4: Start the drive motor, the drive motor drives the drive screw to rotate, thereby driving the support frame to move, adjust the cutting position, and then start the lifting cylinder, the lifting cylinder drives the laser cutting head to move up and down, adjust the cutting thickness, and then start the laser cutting head and the sliding motor to cut the steel plate. During the cutting process, part of the residue generated by the cutting will fall into the collection tank and finally enter the collection drawer; S5: Turn off the laser cutting head, start the push motor, drive the push piece to move in the push slot toward the tilt seat, thereby pushing the steel plate on the workbench to move further toward the laser cutting head, so that the steel plate enters the next cutting position. During the pushing process of the steel plate, the residues left on the workbench will be pushed into the adjacent collecting tank wherever the steel plate passes. The cut steel plate will move toward the tilting seat under the pushing action of the subsequent steel plate, and then enter the receiving tank under the action of the tilting plate. S6: When the steel plate needs to be pushed or collected, the collecting guide rail is started to drive the collecting plate to slide in the width direction of the inclined plate, thereby pushing the cut steel plate to move from one end of the containing groove to the discharge port.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the special setting in the tilting seat, the steel plate plates cut by the steel plate laser cutting device can be automatically stored in the receiving slot, without the need for manual collection and sorting, and without the need for other energy such as electricity. The cut steel plate plates can be transported and collected while the steel plates are being cut and transported. In addition, while the steel plates are being cut and transported, the cutting residues on the upper surface of the workbench can be cleaned in time, that is, the relative movement and friction of the lower surface of the steel plate on the upper surface of the workbench can clean the cutting residues on the upper surface of the workbench. The setting position of the collection slot and the collection drawer, as well as the design method and structure, can directly collect the residues synchronously during cutting. For the residues that have not fallen into the collection slot, that is, on the workbench, the residues that have been cleaned in time can also be collected during the transportation of the steel plate; 2. The support frame, under the joint action of the driving screw, sliding rod and moving groove, can drive the laser cutting head to move quickly in the length direction of the workbench, that is, it can quickly adjust the cutting position of the laser cutting head on the steel plate. The conveying steel plate itself can adjust the cutting position. In conjunction with the adjustment of the position of the laser cutting head, the two-pronged approach can quickly adjust the relative position of the steel plate and the laser cutting head, shortening the adjustment time and improving the adjustment efficiency. The laser cutting head also uses the lifting of the lifting cylinder to adjust the height distance from the steel plate surface, that is, to achieve adaptive adjustment of the cutting thickness of the steel plate; 3. A gap is set between the buffer plate and the bottom surface of the receiving groove, which can prevent the impact-resistant movement of the buffer plate from scratching the bottom surface of the receiving groove, and also prevent the bottom surface of the receiving groove from hindering the movement of the buffer plate. The buffer plate is fixed by a number of rigid springs and arranged vertically, so that the fixation and impact buffering of the buffer plate are both achieved by the rigid springs. Under the support and buffering effect of the rigid springs, the buffer plate can better buffer the steel plate that dives down due to gravity. The evenly distributed rigid springs can also evenly disperse the impact force to ensure the overall good buffering effect of the buffer plate.

[0035] Reference Figure 1 and Figure 2 When the steel plate needs to be cut, the staff first transports the steel plate to the top of the workbench 11 through the steel plate conveying device, and then starts the laser cutting part 2 to cut the steel plate. After cutting, the pushing part 3 is started to move the remaining part back to the cutting position, and the cut steel plate is slid into the receiving groove.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The laser cutting part 2 includes a support frame 21, and moving grooves are provided on both sides of the workbench 11.

The top of the lifting groove 351 is connected with a fixed groove 352 for positioning the clamping block 33. The rotation of the rotating plate 37 drives the clamping block 33 to enter the fixed groove 352. In the initial state, the push plate 32 is located in the placement slot 321, and the two lifting blocks 33 are respectively located in the two lifting slots 351; when the steel plate needs to be pushed, the push plate 32 is located above the placement slot 321, the push plate 32 is slidably connected to the workbench 11, and the two lifting blocks 33 are respectively located in the two fixed slots 352.

[0042] Reference Figure 4 and Figure 5, the push plate 32 and the connecting rod 35 make lifting and reciprocating motions in the hollow cavity of the connecting block 31. When the push plate 32 needs to be pushed, the push plate 32 and the connecting rod 35 are pulled up from the hollow cavity of the connecting block 31. When the steel plate is laid flat on the workbench 11, the push plate 32 and the connecting rod 35 are inserted into the bottom of the hollow cavity of the connecting block 31. At this time, the push plate 32 is embedded in the placement groove 321, and the upper surface of the workbench 11 is in a flat state as a whole. The lifting of the push plate 32 and the connecting rod 35 is driven by the lifting of the lifting member. The lifting of the lifting member can be carried by the operator. The locking height of the push plate 32 and the connecting rod 35 after lifting is achieved by twisting the lifting member. Specifically, the clamping block 33 at the bottom of the lifting member enters the fixed groove 352 in the hollow cavity of the connecting block 31.
