9. The application method of the laser cutting machine applied to the special-shaped sheet metal part is characterized by comprising the following steps of:
Step one: placing the special-shaped sheet metal part on a workbench (703), fixing and limiting the special-shaped sheet metal part through two positioning tools (702), controlling a laser cutting tool (9) to cut the special-shaped sheet metal part corresponding to the position of a blanking hole (706), starting a water pump (202) in the process, enabling the extending end of a cylinder (103) to be shortest at the moment, injecting clean water entering a guide pipe (205) through a water inlet pipe (201) into an L-shaped water spraying pipe (207), and enabling a spray head (206) to spray water for cooling the special-shaped sheet metal part subjected to laser cutting;
Step two: after the laser cutting tool (9) cuts the special-shaped sheet metal part, the extending end of the control cylinder (103) extends to the longest, so that the L-shaped rod (101) drives the pressing ball (106) to press the cutting waste on the special-shaped sheet metal part, the connection between the cutting waste and the special-shaped sheet metal part is bent, the cutting waste provides pressing thrust for the guide plate (705), the guide plate (705) is overturned, at the moment, the piston (203) blocks the input end of the L-shaped water spraying pipe (207) by half, clean water entering the guide pipe (205) flows out through the spray head (206) and the flushing pipe (208), and broken slag dropping on the workbench (703) and the guide plate (705) during laser cutting is flushed;
Step three: the extending end of the control cylinder (103) is contracted to a set length, the pressing ball (106) is separated from the guide plate (705), the guide plate (705) provides thrust reset under the action of a tension spring (701), the cutting waste is convenient to completely separate from the special-shaped sheet metal part after the two bending processes, at the moment, the piston (203) is positioned between the L-shaped water spraying pipe (207) and the water inlet pipe (201), clear water in the guide pipe (205) washes out the slag on the guide groove (204), and the dropped cutting waste enters the recovery box (3) through the guide plate (705), the groove (704) and the guide groove (204);
step four: after the sewage carrying the slag on the workbench (703) flows onto the base (4), the sewage is blocked by the fence (6) and is discharged through the first drain pipe (5), and after the sewage carrying the slag on the diversion trench (204) enters the recovery box (3), the sewage is discharged along with the second drain pipe.
