Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a laser cutting device and a using method for processing high-strength stainless steel flat steel. Background Art

[0002] Laser cutting devices for processing high-strength stainless steel flat steel usually use picosecond-level laser pulses. The ultra-short pulse width enables the laser energy to be released in an extremely short time. The high energy density can instantly melt or evaporate the material, achieving precise cutting. The heat-affected zone is extremely small, effectively avoiding the heating and deformation of the material during the cutting process. The cutting edge has high smoothness and precision, and is particularly suitable for the fine processing of stainless steel flat steel. Existing laser cutting devices mainly consist of a workbench, a cutting gun, and a conveying mechanism;

[0003] During the laser cutting process, when the thickness of the flat steel material is relatively thin, the flat steel material is prone to bending and deformation during transportation, resulting in the material at the cutting position being unable to pass through in a flat state, causing incorrect cutting positions. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A laser cutting device for processing high-strength stainless steel flat steel, comprising:

[0006] A frame body, on the top of which a conveying mechanism is installed. The conveying mechanism is used to drive the flat steel material to move, and a heightening plate is fixedly installed at the central position on the top of the conveying mechanism. A frame plate is fixedly installed inside the conveying mechanism;

[0007] A laser cutting gun, which is installed on the top of the heightening plate. The gun head of the laser cutting gun penetrates through the heightening plate and extends to its bottom;

[0008] A dust suction mechanism, which is symmetrically installed at the bottom along the axial center position of the heightening plate, and the dust suction mechanism is located on both sides of the laser cutting gun;

[0009] The frame plates are symmetrically installed along the axial center position of the conveying mechanism. Slide holes are symmetrically formed at the tops of the frame plates, and shaft blocks are slidably installed at the slide holes. A pressing knife is fixedly installed at the bottom end of the shaft block. A rubber pad is installed between the top of the pressing knife and the frame plate. The rubber pad is sleeved outside the shaft block. A material supporting plate is fixedly installed at the bottom of the frame plate. By cooperating the material supporting plate with the pressing knife, during the cutting process, the flat steel material at the cutting position is pressed. When the plate passes through, the pressing knife is lifted, so that the elastic force generated by compressing the rubber pad is used to push the pressing knife to press the flat steel material. By using the plane at the bottom of the pressing knife and the plane at the top of the material supporting plate, the plate at the cutting position is in a flat state, avoiding the bending deformation of the flat steel with a relatively thin thickness during the conveying process, resulting in incorrect cutting positions. The top of the material supporting plate is in close contact with the bottom of the pressing knife. A circular groove is formed at the center position of the bottom of the material supporting plate. A slag collecting cylinder is fixedly installed at the circular groove at the bottom of the material supporting plate. The two sides of the material supporting plate are inclined planes that slope outward from top to bottom. By using the inclined planes on both sides of the material supporting plate and the arc surfaces at both ends of the bottom of the pressing knife, during the process of the flat steel material entering, the power provided by the conveying mechanism for the flat steel material is used to smoothly lift the pressing knife under the contact pressure, avoiding material jamming during the conveying process. The top of the material supporting plate is a plane, the center position of the bottom of the pressing knife is a plane, and the two ends of the bottom of the pressing knife are arc surfaces.

[0010] Preferably, the conveying mechanism includes a support frame. A rectangular through groove is formed at the center position of the bottom of the support frame. The frame plates are installed at the rectangular through groove of the support frame. A motor is fixedly installed outside the support frame. Groove slots are symmetrically formed at the top of the support frame. Top material bars are fixedly installed at the groove slots of the support frame. By supporting the flat steel material from the bottom by the top material bars, the contact area between the bottom of the material and the conveying mechanism is reduced, the friction force is lowered, the resistance during the movement of the top part under force is reduced, and at the same time, the large-area scratching of the bottom of the stainless steel during the conveying movement is avoided. At the same time, by lifting of the top material bars, the bottom of the cutting position of the plate is in contact with the air, improving the cooling efficiency after cutting. The top of the top material bar is flush with the top of the material supporting plate. A rotating shaft is rotatably installed on the inner wall of the support frame. One end of the rotating shaft is fixedly connected with the output end of the motor through a coupling.

[0011] Preferably, a bushing is installed on the outer side of the rotating shaft. The bushings are symmetrically installed along the central position of the rotating shaft, and fixing sleeves are fixedly installed at both ends of the bushings. Sleeve wheels are fixedly installed on the outer sides of the bushings, and ring groove wheels are fixedly installed on the outer sides of the sleeve wheels. A ring groove is formed at the central position on the outer side of the ring groove wheel, and both sides of the ring groove of the ring groove wheel are inclined planes that slope outward from the inside to both sides. By using the inclined planes on both sides of the ring groove of the ring groove wheel in cooperation with the rubber ring, when the flat steel material shows a tendency to shift, the friction between the flat steel material and the rubber ring drives the rubber wheel to have a tendency to shift. At this time, the pressure of the inclined plane of the ring groove of the ring groove wheel on the rubber ring increases the contact pressure with the material, restricting the material shift and avoiding incorrect cutting positions. A rubber ring is fixedly installed at the ring groove of the ring groove wheel, and the bottom of the rubber ring is in close contact with the top of the ejector bar.

[0012] Preferably, the dust suction mechanism includes a dust suction chamber, which is symmetrically installed along the central axis of the heightening plate. Fixed bars are fixedly installed on the tops of the non-opposite sides of the dust suction chamber. The dust suction chamber is fixedly connected to the bottom of the heightening plate through the fixed bars. Cover frames are fixedly installed on the opposite sides of the dust suction chamber. One end of the cover frame away from the dust suction chamber slopes downward, and a baffle bar is fixedly installed at the bottom of the inner wall of the cover frame. The top of the baffle bar slopes obliquely upward. By the blockage of the baffle bar, foreign objects filtered by the filter plate are restricted. After the foreign objects fall along the filter plate, due to the inclination of the cover frame, the material slides downward and is blocked inside by the baffle bar, preventing foreign objects from falling into the cutting position and affecting the cutting. A filter plate is fixedly connected to one end of the inner wall of the baffle bar close to the dust suction chamber. An arc-shaped groove plate is fixedly installed at the top of the inner wall of the dust suction chamber. Strip grooves are evenly formed on the outer side of the arc-shaped groove plate. A dust suction cloth is fixedly installed on one side of the arc-shaped groove plate close to the filter plate. An air suction pump is fixedly installed on the outer side of the dust suction chamber, and the intake pipe of the air suction pump penetrates through the dust suction chamber and extends into its interior.

[0013] A method for using a laser cutting device for processing high-strength stainless steel flat steel consists of the following steps:

[0014] S1. Manual feeding: Put the high-strength stainless steel flat steel material to be cut into the device, and align the cutting position of the flat steel with the position of the laser cutting gun.

[0015] S2. Material conveying: Drive the placed flat steel material to move through the conveying mechanism, so that the flat steel material is linearly conveyed to the bottom of the laser cutting gun for cutting.

[0016] S3. Pressing and cutting: When the flat steel plate reaches the cutting position, cooperate with the supporting plate and the pressing knife to keep the flat steel material in a flat state during cutting.

[0017] S4. Cutting and dust removal: While cutting the sheet material, start the dust suction mechanism to suck the air at the cutting position, so that the air drives the dust generated by laser cutting into the dust suction mechanism, restricting the spread of the dust.

[0018] The present invention provides a laser cutting device for processing high-strength stainless steel flat steel, having the following beneficial effects:

[0019] First, in the laser cutting device for processing high-strength stainless steel flat steel, through the cooperation of the material supporting plate and the pressing knife, during the cutting process, the flat steel material at the cutting position is pressed. When the sheet material passes through, it jacks up the pressing knife, causing the elastic force generated by compressing the rubber pad, and pushing the pressing knife to press the flat steel material. By using the plane at the bottom of the pressing knife and the plane at the top of the material supporting plate, the sheet material at the cutting position is in a flat state, avoiding the bending deformation of the flat steel with a relatively thin thickness during the conveying process, resulting in incorrect cutting positions.

[0020] Second, in the laser cutting device for processing high-strength stainless steel flat steel, through the inclined planes on both sides of the material supporting plate and the arc surfaces at both ends of the bottom of the pressing knife, during the process of the flat steel material entering, using the power provided by the conveying mechanism for the flat steel material, it smoothly jacks up the pressing knife under the contact pressure, avoiding material jamming during the conveying process.

[0021] Third, in the laser cutting device for processing high-strength stainless steel flat steel, the material is supported at the bottom by the ejector bar, reducing the contact area between the bottom of the material and the conveying mechanism, reducing the friction force, reducing the resistance when the top of the material moves under force, and at the same time avoiding large-area scratching of the bottom of the stainless steel during the conveying movement. At the same time, through the jacking of the ejector bar, the bottom of the sheet material at the cutting position is in contact with the air, improving the cooling efficiency after cutting.

[0022] Fourth, in the laser cutting device for processing high-strength stainless steel flat steel, through the cooperation of the inclined planes on both sides of the annular groove of the annular groove wheel and the rubber ring, when the flat steel material shows a tendency to shift, using the friction between the flat steel material and the rubber ring, driving the rubber wheel to show a tendency to shift. At this time, the pressure of the inclined plane of the annular groove of the annular groove wheel on the rubber ring increases the contact pressure with the material, restricting the material shift and avoiding incorrect cutting positions.

[0023] Fifth, in the laser cutting device for processing high-strength stainless steel flat steel, through the blocking of the material blocking bar, the foreign objects filtered out by the filter plate are restricted. After the foreign objects fall along the filter plate, due to the inclination of the cover frame, the material slides downward and is blocked inside by the material blocking bar, preventing foreign objects from falling into the cutting position and affecting the cutting.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] The first embodiment is as Figures 1 to 4 shown, and the present invention provides a technical solution:

[0037] A laser cutting device for processing high-strength stainless steel flat steel, comprising:

[0038] A frame body 1, on the top of which a conveying mechanism 2 is installed. The conveying mechanism 2 is used to drive the flat steel material to move, and a heightening plate 5 is fixedly installed at the central position on the top of the conveying mechanism 2, and a frame plate 6 is fixedly installed inside the conveying mechanism 2;

[0039] A laser cutting gun 4, which is installed on the top of the heightening plate 5. The gun head of the laser cutting gun 4 penetrates through the heightening plate 5 and extends to its bottom;

[0040] A dust suction mechanism 3, which is symmetrically installed at the bottom of the heightening plate 5 along the central axis position, and the dust suction mechanism 3 is located on both sides of the laser cutting gun 4;

[0041] The frame plates 6 are symmetrically installed along the central axis position of the conveying mechanism 2, and sliding holes are symmetrically opened at the tops of the frame plates 6, and shaft blocks 9 are slidably installed at the sliding holes. The bottom ends of the shaft blocks 9 are fixedly installed with pressing knives 7. A rubber pad 10 is installed between the top of the pressing knife 7 and the frame plate 6. The rubber pad 10 is sleeved outside the shaft block 9. A supporting plate 11 is fixedly installed at the bottom of the frame plate 6. Through the cooperation of the supporting plate 11 and the conveying mechanism 2, the flat steel plate is supported by the supporting plate 11. At the same time, with the cooperation of the pressing knife 7 pressing on the top of the plate, when the flat steel plate passes through the gap between the pressing knife 7 and the supporting plate 11, it is oppressed and restricted, and keeps a flat state to pass through the bottom of the laser cutting gun 4 to realize cutting. At the same time, the circular groove of the supporting plate 11 cooperates with the slag collecting cylinder 8 to collect the metal chips generated by cutting, so that they fall into the slag collecting cylinder 8 under their own gravity. The top of the supporting plate 11 is closely attached to the bottom of the pressing knife 7, and a circular groove is opened at the central position of the bottom of the supporting plate 11. A slag collecting cylinder 8 is fixedly installed at the circular groove at the bottom of the supporting plate 11. The two sides of the supporting plate 11 are inclined planes that slope outward from top to bottom. When the plate passes through the gap between the supporting plate 11 and the pressing knife 7, through the inclined plane of the supporting plate 11 and the arc surfaces at both ends of the bottom of the pressing knife 7, the material is driven by the conveying mechanism 2 to push the pressing knife 7 upward through the contact pressure, so that the pressing knife 7 compresses the rubber pad 10 to deform, and the pressing knife 7 vertically moves upward under the restriction of the shaft block 9. At the same time, the deformed rubber pad 10 generates an elastic force to push the pressing knife 7 to press the passing plate. The top of the supporting plate 11 is a plane, the central position of the bottom of the pressing knife 7 is a plane, and the two ends of the bottom of the pressing knife 7 are arc surfaces.

[0042] Second embodiment. On the basis of the first embodiment, please refer to Figures 5 to 7As shown in the figure, the conveying mechanism 2 includes a support frame 21. A rectangular through groove is formed at the center of the bottom of the support frame 21. The frame plate 6 is installed at the rectangular through groove of the support frame 21. The rotation of the rotating shaft 25 is driven by the motor 23, so that the rotating shaft 25 rotates. During the rotation of the rotating shaft 25, due to the contact pressure between the rubber ring 24 and the plate when the plate is placed, the sleeve wheel 27 is driven to rotate by the shaft sleeve 26 during the rotation process, so that the sleeve wheel 27 drives the rubber ring 24 to rotate through the ring groove wheel 28. The motor 23 is fixedly installed on the outside of the support frame 21, and strip grooves are symmetrically formed at the top of the support frame 21. The top material strips 22 are fixedly installed at the strip grooves of the support frame 21. The top of the top material strip 22 is flush with the top of the material supporting plate 11. The rotating shaft 25 is rotatably installed on the inner wall of the support frame 21. One end of the rotating shaft 25 is fixedly connected to the output end of the motor 23 through a coupling.

[0043] The shaft sleeve 26 is installed on the outside of the rotating shaft 25. The shaft sleeve 26 is symmetrically installed along the center position of the rotating shaft 25, and fixed sleeves 29 are fixedly installed at both ends of the shaft sleeve 26. The sleeve wheels 27 are fixedly installed on the outside of the shaft sleeve 26. The ring groove wheels 28 are fixedly installed on the outside of the sleeve wheels 27. A ring groove is formed at the center position on the outside of the ring groove wheel 28. During the rotation process, due to the friction force between the rubber ring 24 and the material, the movement of the material is mobilized, so that the material passes through the lower part of the laser cutting gun 4 for cutting. At the same time, during the conveying process, by using the friction force between the rubber ring 24 and the material, and in cooperation with the contact between the inclined surfaces on both sides of the ring groove of the ring groove wheel 28 and the rubber ring 24, when the plate shows a tendency of tilting and offsetting, by using the inclined surface of the ring groove, a squeezing tendency appears at the side position of the rubber ring 24, increasing the friction force with the material and restricting the tilting and offsetting of the material. The two sides of the ring groove of the ring groove wheel 28 are inclined surfaces that incline from the inside to the outside on both sides. The rubber ring 24 is fixedly installed at the ring groove of the ring groove wheel 28. The bottom of the rubber ring 24 is in close contact with the top of the top material strip 22.

[0044] Third embodiment. On the basis of the first and second embodiments, please refer to Figures 8 to 10As shown in the figure, the dust suction mechanism 3 includes a dust suction bin 31. The dust suction bin 31 is symmetrically installed along the central axis position of the heightening plate 5. Fixed bars 35 are fixedly installed at the tops of the non-opposite sides of the dust suction bin 31. Through the suction of the suction pump 36, the air inside the dust suction bin 31 is pumped out, so that the dust suction bin 31 cooperates with the cover frame 32. Utilizing the inclination of the cover frame 32, the dust generated at the laser cutting position is driven by the air and moves towards the inside of the dust suction bin 31. The dust suction bin 31 is fixedly connected to the bottom of the heightening plate 5 through the fixed bars 35. Cover frames 32 are fixedly installed on the opposite sides of the dust suction bin 31. One end of the cover frame 32 away from the dust suction bin 31 inclines downward. A baffle strip 33 is fixedly installed at the bottom of the inner wall of the cover frame 32. The top end of the baffle strip 33 inclines obliquely upward. A filter plate 34 is fixedly connected to one end of the inner wall of the baffle strip 33 close to the dust suction bin 31. During the movement process, the dust first passes through the cover frame 32 and is preliminarily filtered by the filter plate 34 installed on the inner wall of the cover frame 32. Then, after the dust passes through the filter plate 34, it enters the inside of the dust suction bin 31. After entering the inside, the air drives the dust to pass through the dust suction cloth 38. When in use, by wetting the dust suction cloth 38, the dust particles are blocked when the dust passes through, and are attached to the surface of the dust suction cloth 38. An arc-shaped groove plate 37 is fixedly installed at the top of the inner wall of the dust suction bin 31. Strip grooves are evenly opened on the outer side of the arc-shaped groove plate 37. A dust suction cloth 38 is fixedly installed on one side of the arc-shaped groove plate 37 close to the filter plate 34. An air suction pump 36 is fixedly installed on the outer side of the dust suction bin 31. The intake pipe of the air suction pump 36 penetrates through the dust suction bin 31 and extends to its inside.

[0045] The usage method of a laser cutting device for processing high-strength stainless steel flat steel consists of the following steps:

[0046] S1. Manual feeding. Put the high-strength stainless steel flat steel material to be cut into the device, and align the cutting position of the flat steel with the position of the laser cutting gun 4.

[0047] S2. Material transportation. Drive the placed flat steel material to move through the transportation mechanism 2, so that the flat steel material is linearly conveyed to the bottom of the laser cutting gun 4 for cutting.

[0048] S3. Material pressing and cutting. When the flat steel plate reaches the cutting position, cooperate the material supporting plate 11 with the pressing knife 7 to keep the flat steel material in a flat state during cutting.

[0049] S4. Cutting and dust removal. While cutting the plate, start the dust suction mechanism 3 to pump the air at the cutting position by the dust suction mechanism 3, so that the air drives the dust generated by laser cutting into the dust suction mechanism 3 to limit the diffusion of the dust.

[0050] During use, the worker places the high-strength stainless steel flat steel material to be cut into the conveying mechanism 2. The conveying mechanism 2 drives the movement of the flat steel plate material, so that the material reaches directly below the laser cutting gun 4. After the worker aligns the cutting position, the conveying mechanism 2 and the dust suction mechanism 3 are started. The conveying mechanism 2 drives the material through the laser cutting gun 4, and the material is cut by the laser cutting gun 4. At the same time, the dust suction mechanism 3 absorbs the smoke and dust generated during cutting.

[0051] During the cutting process, the supporting plate 11 cooperates with the conveying mechanism 2 to support the flat steel plate material through the supporting plate 11. At the same time, it cooperates with the pressing knife 7 to press the plate material on the top of the plate, so that when the flat steel plate material passes through the gap between the pressing knife 7 and the supporting plate 11, it is oppressed and restricted, and passes through the bottom of the laser cutting gun 4 in a flat state to achieve cutting. At the same time, the circular groove of the supporting plate 11 cooperates with the slag collection cylinder 8 to collect the metal chips generated during cutting, so that they fall into the slag collection cylinder 8 under their own gravity. At the same time, when the plate material passes through the gap between the supporting plate 11 and the pressing knife 7, through the inclined surface of the supporting plate 11 and the arc surfaces at both ends of the bottom of the pressing knife 7, the material is driven by the conveying mechanism 2 to push the pressing knife 7 upward through the contact pressure, so that the pressing knife 7 compresses the rubber pad 10 to deform, and the pressing knife 7 vertically moves upward under the restriction of the shaft block 9. At the same time, the deformed rubber pad 10 generates elastic force to push the pressing knife 7 to press the passing plate material.

[0052] In the conveying mechanism 2, the motor 23 drives the rotation of the rotating shaft 25, so that the rotating shaft 25 rotates. During the rotation of the rotating shaft 25, through the contact pressure between the rubber ring 24 and the plate material when the plate material is placed, the sleeve wheel 27 is driven to rotate by the shaft sleeve 26 during the rotation process, so that the sleeve wheel 27 drives the rubber ring 24 to rotate through the ring groove wheel 28. During the rotation process, the material is mobilized to move through the friction force between the rubber ring 24 and the material, so that the material passes through below the laser cutting gun 4 for cutting. At the same time, during the conveying process, using the friction force between the rubber ring 24 and the material, and cooperating with the contact between the inclined surfaces on both sides of the ring groove of the ring groove wheel 28 and the rubber ring 24, when the plate material shows a tendency of tilting and offsetting, using the inclined surface of the ring groove, a squeezing tendency appears at the side position of the rubber ring 24, increasing the friction force with the material and restricting the tilting and offsetting of the material.

[0053] In the dust suction mechanism 3, through the suction of the suction pump 36, the air inside the dust suction bin 31 is pumped out, so that the dust suction bin 31 cooperates with the cover frame 32. By virtue of the inclination of the cover frame 32, the dust generated at the laser cutting position is driven by the air and moves towards the inside of the dust suction bin 31. During the movement, the dust first passes through the cover frame 32 and is preliminarily filtered by the filter plate 34 installed on the inner wall of the cover frame 32. Subsequently, after passing through the filter plate 34, the dust enters the inside of the dust suction bin 31. After entering the inside, the air drives the dust to pass through the dust suction cloth 38. During use, by wetting the dust suction cloth 38, the dust particles are blocked when passing through, and are attached to the surface of the dust suction cloth 38.
