[0045] A method for using a laser cutting device for processing high-strength stainless steel flat steel, comprising the following steps:

[0046] S1, manually placing the high-strength stainless steel flat steel material to be cut into the device, and corresponding the cutting position of the flat steel to the position of the laser cutting gun 4;

[0047] S2, material conveying, moving the placed flat steel material by the conveying mechanism 2, so that the flat steel material is transmitted to the bottom of the laser cutting gun 4 along a straight line, and the material is cut;

[0048] S3, pressing and cutting, when the flat steel plate reaches the cutting position, the flat steel material is kept in a planar state during cutting by cooperation of the material supporting plate 11 and the material pressing knife 7;

[0049] S4, cutting and dust removal, while cutting the plate, starting the dust collection mechanism 3 to extract the air at the cutting position, so that the air drives the smoke and dust generated by the laser cutting into the dust collection mechanism 3, and the diffusion of the smoke and dust is limited.

[0050] In use, the worker will put the high-strength stainless steel flat steel material to be cut into the conveying mechanism 2, and the flat steel plate material is moved by the conveying mechanism 2, so that the material reaches the position directly below the laser cutting gun 4. After the worker adjusts the cutting position, the conveying mechanism 2 and the dust collection mechanism 3 are started, so that the conveying mechanism 2 drives the material to pass through the laser cutting gun 4, and the material is cut by the laser cutting gun 4, and the dust generated during cutting is absorbed by the dust collection mechanism 3.

[0051] During cutting, the flat steel plate is supported by the material supporting plate 11 cooperating with the conveying mechanism 2, and the material is pressed on the top of the plate by the pressing knife 7, so that the flat steel plate is pressed and limited when passing through the gap between the pressing knife 7 and the material supporting plate 11, and the flat steel plate is kept in a plane state passing through the bottom of the laser cutting gun 4 to realize cutting. At the same time, the circular groove of the material supporting plate 11 cooperates with the slag collecting cylinder 8 to collect the metal chips generated during cutting, so that they fall into the slag collecting cylinder 8 under their own gravity. When the plate passes through the gap between the material supporting plate 11 and the pressing knife 7, the inclined surface of the material supporting plate 11 and the arc surface at both ends of the bottom of the pressing knife 7 make the material move upward by contact pressure under the driving of the conveying mechanism 2, so that the pressing knife 7 is pushed upward, the rubber pad 10 is compressed and deformed, and the pressing knife 7 is vertically moved upward under the limitation 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.

[0052] In the conveying mechanism 2, the rotating shaft 25 is driven to rotate by the motor 23, so that the rotating shaft 25 rotates. In the process of rotating the rotating shaft 25, the contact pressure between the rubber ring 24 and the plate when the plate is put in is used to drive the sleeve 26 to rotate the sleeve wheel 27, so that the sleeve wheel 27 drives the rubber ring 24 to rotate through the ring groove wheel 28. In the process of rotating, the friction between the rubber ring 24 and the material is used to mobilize the material to move, so that the material passes below the laser cutting gun 4 for cutting. At the same time, in the process of conveying, the friction between the rubber ring 24 and the material is used to cooperate with the inclined surfaces on both sides of the ring groove of the ring groove wheel 28 and the contact between the rubber ring 24 and the inclined surfaces. When the plate appears to be inclined and deviated, the inclined surfaces of the ring groove are used to make the side edges of the rubber ring 24 appear to be extruded, so as to increase the friction between the rubber ring 24 and the material and limit the inclination and deviation of the material.

[0053] In the dust collection mechanism 3, the air inside the dust collection bin 31 is extracted by the suction of the suction pump 36, and the dust generated by the laser cutting position is driven by the air and moves to the inside of the dust collection bin 31 through the cooperation of the dust collection bin 31 and the cover frame 32. In the process of movement, the dust first passes through the filter plate 34 installed on the inner wall of the cover frame 32, and then enters the inside of the dust collection bin 31. After entering the inside, the air drives the dust to pass through the dust cloth 38. In use, the dust cloth 38 is wetted to block the dust particles when the dust passes through, so that the dust particles adhere to the surface of the dust cloth 38.

A laser cutting apparatus for high strength stainless steel flat steel processing according to claim 4, characterized in that: The top of the inner wall of the dust collection bin (31) is fixedly installed with an arc-shaped groove plate (37), the outer side of the arc-shaped groove plate (37) is uniformly provided with a groove, and the side of the arc-shaped groove plate (37) close to the filter plate (34) is fixedly installed with a dust collection cloth (38), the outer side of the dust collection bin (31) is fixedly installed with a suction pump (36), and the air inlet pipeline of the suction pump (36) penetrates through the dust collection bin (31) and extends into the dust collection bin (31).

6. A method of using a laser cutting apparatus for high strength stainless steel flat steel processing according to any one of claims 1-5, characterized in that, The following steps are included: S1, manual material, the high-strength stainless steel flat steel material needed to be cut is put into the equipment, and the cutting position of the flat steel is corresponding to the position of the laser cutting gun (4); S2, material conveying, the put-in flat steel material is driven to move through the conveying mechanism (2), so that the flat steel material passes through the bottom of the laser cutting gun (4) along a straight line, so that the material is cut; S3, pressing and cutting, when the flat steel plate reaches the cutting position, the flat steel material is kept in a plane state during cutting through the cooperation of the material supporting plate (11) and the material pressing knife (7); S4, cutting and dust removal, while cutting the plate, the dust collection mechanism (3) is started to suck the air at the cutting position, so that the air drives the smoke and dust generated by laser cutting into the dust collection mechanism (3), thereby limiting the diffusion of the smoke and dust.
