s1, fixing a workpiece by using a clamp, sweeping a plane, determining a machining position, starting a telescopic rod 2, driving a machine table 3, a main shaft 5, a fixing cylinder 7, a sleeve 10 and a liquid outlet plate 11 to move downwards, and enabling the liquid outlet plate 11 to be abutted against the workpiece;
S2, before the piston 18 is not separated from the inner wall of the sealing cylinder 19, the sleeve 10, the liquid outlet plate 11 and the sealing cylinder 19 move upwards relative to the piston 18, namely the piston 18 moves downwards, so that the cooling liquid 16 is pushed to flow downwards and be supplemented into the liquid outlet hole 13;
S3, when the piston 18 is separated from the sealing cylinder 19 and enters the liquid storage cavity 15, the fixed cylinder 7, the sealing cylinder 19, the sleeve 10 and the liquid outlet plate 11 are communicated, and the cooling liquid 16 is horizontally sprayed to the outer surface of the cutter 6 through the liquid outlet hole 13 naturally downwards;
S4, when the cutter 6 moves upwards, the main shaft 5 integrally drives the fixed cylinder 7 to move upwards, so that the piston 18 moves upwards and resets relative to the sealing cylinder 19, negative pressure is generated to the inner cavity of the liquid storage cavity 15 in the process that the piston 18 moves upwards to reset after entering the inner wall of the sealing cylinder 19, and the cooling liquid 16 in the liquid outlet hole 13 is adsorbed to the placing groove 12 for storage;
S5, finishing punching of the workpiece.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
