Convex point grid platform of plasma and flame numerical control cutting machine

Abstract

The invention discloses a convex point grid platform of a plasma and flame numerical control cutting machine. The convex point grid platform comprises square steel plates, longitudinal rib plates and convex point plates, wherein the square steel plates and the longitudinal rib plates are longitudinally arranged at intervals, the convex point plates are transversely arranged, and a double-layer grid structure is formed. According to the convex point grid platform disclosed by the invention, because the convex point grid platform difficultly deforms, the cutting accuracy is improved; and the convex point grid platform is safe to operate.

Description

technical field [0001] The invention relates to a grid platform, in particular to a raised dot grid platform of a plasma and flame numerical control cutting machine. Background technique [0002] The plasma CNC cutting machine platform is responsible for the blanking and cutting of all plate parts in the shipbuilding process. In the prior art, the submerged grid platform of the plasma water tank workbench is generally made of straight flat steel bars to form a flat grid. After a period of sheet metal cutting and use, serious damage and deformation will occur. It affects the cutting accuracy; and the gap between the parallel grids is inconvenient for the operator to walk safely. [0003] Since the flat steel roots of the plane grid are all in contact with the bottom of the steel plate placed on it, the plane grid is cut when the steel plate is cut; moreover, the carbide slag produced by the condensation of molten steel at high temperature accumulates in the gap, and the melt...
