目前生产中的鋼板下料,已广泛采用氧乙炔半自动切割机。国內电动式半自动切割机已有定型生产,并且广泛应用。但是,电动設备还存在一定缺点,如:易損坏、修理复杂和价格昂貴,其次在采用低压乙炔发生器切割較厚鋼板时,还不太适应。鉴于这种情况能否采用风动和机械式切割机来代替电动式切割机,已为操作工人所十分 The current production of steel cutting, has been widely used oxyacetylene semi-automatic cutting machine. Domestic electric semi-automatic cutting machine stereotypes have been produced, and widely used. However, there are still some shortcomings of electric equipment, such as: easy to damage, complex and expensive to repair, followed by the use of low-pressure acetylene generator to cut thicker steel, it is not well adapted. In view of this situation can use pneumatic and mechanical cutting machine instead of electric cutting machine, has been for the operation of workers
