As shown in fig. 12, when the thickness of the plate is constant, the smaller the aperture, the smaller the self weight of the cut disc, and the larger the rotatable angle in the round hole, the more easily the disc is stuck in the round hole, and since the hole wall and the disc are the same material, if the raw material is re-determined at this time, the disc and the round hole will be damaged.
When the cutting machine is particularly used, firstly, a user needs to move the workpiece 51 to a proper position through the movement of the X-axis platform 47 and the Y-axis platform 48, and the cutter Kong Zhuaipan and the supporting round table 43 are coaxially arranged, so that the position above the supporting round table 43 is a cutting area at the moment;
the high-pressure air gap air inlet mechanism 1 is descended by the descending of the lifting cantilever 39, firstly, the valve shell 13 contacts the workpiece 51, then the return spring 12 is compressed in the process of continuing descending of the high-pressure cavity body 10 until the sealing ring 11 contacts and is attached to the workpiece 51, the high-pressure cavity body 10 forms an independent space, at the moment, the external connector 19 is communicated with the external notch 16, and air blown out of the air pump can enter the high-pressure cavity body 10 through the pressure relief assembly 22;
as the air pressure in the high-pressure cavity body 10 gradually rises, the cylinder valve core 23 overcomes the elasticity of the pre-tightening spring 24 to slide until the inner notch 17 is completely closed when the plugging part 32 is overlapped with the inner notch 17, at this time, the inside of the high-pressure cavity body 10 is a closed cavity with higher air pressure, and when the pressure in the pressure relief cavity 27 exceeds a certain range after the high-pressure cavity body 10 and the pressure relief cavity 27 are no longer penetrated, the pressure is discharged through the pressure relief valve 36, so that frequent starting and stopping of the air pump are avoided;
the rotation of the cutter Kong Zhuaipan can lead the light rays emitted by the laser cutting head 9 to irradiate the workpiece 51 in a circular track and cut the workpiece 51, and in order to ensure that the air is distributed in advance in the gap between the waste and the hole wall, a cyclic irradiation cutting method can be adopted, namely, the cutting is completed layer by layer through two to three cycles, so that the air fills the gap between the waste and the hole wall before the cutting is completely completed, and the stability of the technical effect of avoiding the contact between the waste and the hole wall is improved;
after cutting and penetrating, air in the high-pressure cavity body 10 is sprayed out through the workpiece 51, the air pressure in the high-pressure cavity body 10 is reduced, but the air in the pressure relief cavity 27 is continuously replenished, so that the air pressure in the high-pressure cavity body 10 is ensured to be enough, after the round waste is completely cut off, the waste can vertically fall under the condition of not overturning due to a stable air gap between the waste and the hole wall until the waste is separated from the hole wall and falls into the waste box 38 through the hollow channel 45, and the embarrassing condition that the waste is blocked in the hole wall when overturning is avoided to a great extent;
the high-pressure air is discharged after being filtered by the filter screen 44, so that dust in the waste box 38 can be prevented from scattering, dust on the tracks of the Y-axis platform 48 and the X-axis platform 47 can be blown away from the inside, and the maintenance and cleaning period of the guide rail can be prolonged;
after the cut is completed, the lifting cantilever 39 is moved upward, and then the workpiece 51 is moved to the next station by the movement of the Y-axis table 48 and the clamping assembly 49.
