The invention relates to the technical field of plate
machining equipment, in particular to a plate
cutting machine and a
cutting method. The plate
cutting machine comprises a bottom plate, wherein aguide rail is arranged on the top wall of the bottom plate, side plates are fixed to the two sides of the bottom plate, a
workbench slidably is arranged on the guide rail, a driving
assembly is arranged at the bottom of the
workbench, a rotating table is arranged at the top of the
workbench, a clamping
assembly is arranged at the top of the rotating table, stand columns are fixed to the four corners of the top wall of the bottom plate, a top plate is fixed to the tops of the stand columns, a cutting
assembly, a power assembly and a reciprocating assembly are sequentially arranged on the bottomwall of the top plate, a mounting block is fixed to the bottom of the reciprocating assembly, a
grinding block is clamped to the bottom of the mounting block, a
laser transmitter is fixed to the bottom wall of the top plate, and a
laser receiver is fixed to the upper wall of the bottom plate. When the plate cutting device is used, the cutting angle of plates can be adjusted, the plates of different sizes can be clamped within a certain range, the application range is wide, the arranged power assembly can drive the cutting assembly and the reciprocating assembly to work, the use number of motors is reduced,
energy consumption is reduced, and meanwhile the
grinding block is convenient to replace.
