s42: in the punching process, the airflow detection module acquires airflow ratio coefficients in real timeAnd transmits it to the scrap-skipping judging module, the scrap-skipping judging module pair +.>And grading the air flow blocking condition, and transmitting the blocking degree grade data to the data adjusting module after the dancing judging module acquires the blocking degree grade data.

10. A casting punching apparatus according to claim 8, wherein: the specific steps of the S5 are as follows:

s51: when no scraps jump is generated on the side surface of the sliding seat (14), the average value of the pressures born by the two groups of pressure sensing springs (27) is recorded and is recorded as an initial extrusion pressure value；

S52: when one side of the casting isWhen the punching process is finished, the roller detection module takes the maximum pressure value received by the two groups of pressure sensing springs (27) as a real-time extrusion pressure value in the rotating cleaning process of the roller (25), and records the maximum pressure value as；

S53: the data acquisition module acquires an initial extrusion pressure valueAnd real-time extrusion pressure value->Transmitting the waste scraps to a scrap-skipping judging module, and judging the quantity of the adhered waste scraps on the surface of the sliding seat (14) by the scrap-skipping judging module according to the ratio of the two, wherein the ratio of the two is ∈10>；

S54: when the chip jump judging module judges the data, the chip jump judging module judges the data according toThe values were graded for adhesion.
