1. a kind of laser cutting machine air pressure adjustment autoalarm, including cutting body (1), cutting body (1) is provided with sharpBare headed (2), laser head (2) is connected with auxiliary gas box (3), it is characterized in that:

  • described laser head (2) and auxiliary gas box(3) be connected with electromagnetic valve (4) between, electromagnetic valve (4) is connected with cutting body (1), electromagnetic valve (4) and laser head (2) itBetween be connected with air pressure adjustment alarm indicator table (5), air pressure adjustment alarm indicator table (5) is connected with alarm lamp (6), assists gasIt is connected with regulating valve (7), air pressure adjustment alarm indicator table (5) is provided with positive normal pressure between body container (3) and electromagnetic valve (4)Low value graticule (9), positive normal pressure peak graticule (10), lower-pressure limit value graticule (11) and high-pressure stage limit value graticule (12);

    AuxiliaryGas out transmits to regulating valve (7) through trachea from auxiliary gas box (3), after air pressure adjustment alarm indicator table (5),Enter trachea, import laser head (2) through lathe bed tank chain, normal atmospheric pressure value scope be positive normal pressure minimum graticule (9) withBetween positive normal pressure peak graticule (10), when air pressure is less than positive normal pressure minimum, when not arriving lower-pressure limit value, alarm lamp (6)Will be bright, when atmospheric pressure value is higher than positive normal pressure peak, alarm lamp (6) also can be bright, when atmospheric pressure value is less than lower-pressure limit value or heightWhen high-pressure stage limit value, electromagnetic valve (4) can control cutting body (1) starting protection system, work stoppage.
