Abstract
The utility model relates to a CNC (computerized numerical control) flame/plasma cutting machine sharing one set of lifting mechanism, which adopts an upper limit-switch and a lower limit-switch in a set of lifting mechanism to directly control the operation of two relays; in the range of normal travel working, the upper limit-switch and the lower limit-switch are electrically occluded; and when the upper or the lower limit exceeds the travel range, the corresponding relays lose power and then working conditions of a flame-manner lifting motor and a plasma-manner lifting motor can be controlled. When a selection switch selects the plasma manner, a plasma cutting torch controls the operation of one of the relays, supplies an arc voltage increasing device with 24V power, and controls the operation of one of the lifting motors by limiting one of the relays; and when a flame manner is selected, a flame cutting torch controls the operation of the other relay KA2, and controls the operation of one of the lifting motors by limiting the relay KA2, therefore, the flame cutting manner and the plasma cutting manner can be switched and the lifting motors are not influenced by each other during working. The CNC flame/plasma cutting machine has the advantages of reduction in material cost, complete cutting functions and higher cost performance.
