The filtered cutting fluid flows into the collection frame 5113 and is controllably discharged through the pipe 5114 and valve, achieving resource recovery and efficient waste separation.

[0026] Example 3: Based on Example 1 and Example 2, a preferred embodiment of a metal cutting processing device with a chip blocking prevention function provided by the present invention is as follows: Figure 1 - Figure 3 、 Figure 6 and Figure 7 As shown: the anti-clogging component 52 includes an air jet 527 and a nozzle 528 located above the processing table 503. The top surface of the air jet 527 is fixedly connected to the top surface of the interior of the processing box 1. The top surface of the nozzle 528 is fixedly passed through the bottom surface of the air jet 527 and extends into the interior of the air jet 527. A heat dissipation tube 521 is provided above the processing box 1. The bottom surface of the heat dissipation tube 521 is fixedly connected to four support rods 522. The bottom end surfaces of the four support rods 522 are all fixedly connected to the top surface of the processing box 1. The top surface of the interior of the heat dissipation tube 521 is fixedly connected to a third motor 523. The bottom end surface of the output rod of the third motor 523 is fixedly connected to a blade. 524, a vent pipe 526 is provided below the blade 524, the bottom end surface of the vent pipe 526 is fixedly passed through the bottom surface of the inner side of the heat dissipation tube 521, the processing box 1 and the top surface of the jet pipe 527, and extends to the inside of the jet pipe 527. Through the anti-blocking component 52, the third motor 523 is used to drive the blade 524 to rotate at high speed, and the external air enters the heat dissipation tube 521 after being purified by the first filter 525. The airflow is transported to the jet pipe 527 through the vent pipe 526 and is finally ejected downward by the nozzle 528. The strong airflow directly blows the processing table 503 and the cutting knife 506, forcing the debris to leave the processing area and reduce the residue.

[0027] An air inlet is formed through the top surface of the heat dissipation tube 521 , and a first filter 525 is fixedly connected to the inner wall of the air inlet.

[0028] An air outlet is formed through the side of baffle 516, and a second filter 529 is fixedly connected to the inner wall of the air outlet. The first filter 525 and the second filter 529 respectively prevent external impurities from entering the heat dissipation system and the processing chamber, ensuring internal cleanliness. The observation window 4 facilitates real-time monitoring of the processing status. The chamber door 3 and the retractable baffle 516 simplify maintenance and cleaning.

[0029] During use, a metal workpiece is placed on the processing table 503 and fixed on the processing table 503 by using a clamp 504. The electric push rod 505 is turned on, and the output rod of the electric push rod 505 extends to drive the cutting blade 506 to move downward, so that the cutting blade 506 cuts the metal workpiece on the processing table 503 downward. The first motor 502 is turned on, and the output rod of the first motor 502 drives the processing table 503 to rotate, thereby driving the metal processing table to move to different positions for cutting, and at the same time, the debris on the processing table 503 can be thrown away. The third motor 523 is turned on. The output rod of the third motor 523 drives the blades 524 to rotate, causing the blades 524 to increase the air flow in the heat dissipation tube 521. The flowing air enters the air injection pipe 527 through the vent pipe 526 and is blown downward through the nozzle 528, thereby blowing off the chips on the cutting blade 506 and the processing table 503. The filter plate 511 filters the debris and cutting fluid. The cutting fluid flows into the collection frame 5113 after passing through the filter plate 511. The valve is opened, and the cutting fluid collected in the collection frame 5113 is discharged through the drain pipe 5114. The second motor 518 is turned on. The output rod of the second motor 518 drives the connected worm 519 to rotate. The worm 519 and the worm wheel 5111 are engaged and driven, so that the rotating rod 5110 rotates, thereby causing the rotating rod 5110 to drive the cam 5112 to rotate. The wheel 5112 rotates to squeeze the filter plate 511 to move upward. When the filter plate 511 moves, it drives the slide plate 515 and the slide rod 513 to slide in the slide cylinder 512. The spring 514 is pulled. When the cam 5112 no longer squeezes the filter plate 511, the force of the spring 514 drives the filter plate 511 to move downward, thereby causing the filter plate 511 to vibrate to prevent debris from clogging the filter plate 511. The baffle 516 is opened and the debris is discharged from the chip discharge slot in conjunction with the blowing of the flowing air.
