Cutting Plate Machine Blade is in the movement on the bladeborrow and fixed the blade, and the use of reasonable blade gap, toall sorts of thickness of the sheet metal applied shear force, makeaccording to the size of the board to fracture separation. Cuttingmachine working principle and structural plate shears used tocutting line edge in the process of sheet metal blank. Shearingprocess should be able to guarantee is cut the line of the sheetmetal shearing surface sex and parallel degree requirements, and toreduce the distortion plank to get high quality workpiece. Cuttingmachine belong to one of the forging machinery, main effect ismetal processing industry.
