Circular plate gas cutting device

The utility model discloses a circular plate gas cutting device, comprising a body, a fixed part connected with one end of the body, the body doing the circumference motion round the fixed part, a movable end slidably arranged on the body, and an air gun connected with the movable end and moving with the movable end on the body. By adopting the circular plate gas cutting device in the utility model, the problem that when the circular plate is cut with an artificial method, due to the operator, the shape and size of the cut raw material can not be strictly controlled, thus the rejection and waste can be caused in the batch production, is solved, the problems in the mechanical method, such as a laser method, a plasma method and the like that the early stage investment is larger and the cost is high are solved, thus the cost is lower and the cutting size is accurate.
