Description

technical field

[0001] The invention relates to an underwater cutting device, in particular to a numerical control plasma underwater cutting device. Background technique

[0002] In the shipbuilding industry, it is often necessary to cut large sheet metal to meet various needs in shipbuilding. However, when cutting various metal plates, noise and dust will be generated when the cutting equipment is in contact with the plates. If workers inhale excessive dust during the operation of cutting plates, it will seriously affect their health. Therefore people thought of adopting the water cutting method to cut the plate. In the existing water cutting equipment, an inflatable rubber airbag is usually installed at the bottom of the pool. After inflating, the volume of the airbag increases to increase the water level of the pool, and vice versa. However, the water level changes slowly in this method, and the airbag is easily damaged. Another way is to lift the cutting platform devi...
