The utility model relates to sheet
metal cutting technical field, and disclose a
cutting device for express cabinet sheet
metal, including support angle, the top fixed
assembly of support angle has support frame, the outer wall fixed mounting of support frame has crossbeam, the top of crossbeam is equipped with
dust fall subassembly, the top fixed mounting of support frame has mesa. Through the
signal of controller emission, can make
micro motor start, make screw rod can rotate, and can drive the sliding block to move on the outer wall of screw rod, and then can drive the
abutment block along the virtual center line direction of screw rod and move, can make four
abutment blocks can move each other, and move to the inner wall of
abutment block and the outer wall of sheet
metal contact, make the device can limit the fixed effect of different size sheet metal, simultaneously because abutment block is prepared from soft
silica gel, can make it when contacting with sheet metal not to cause damage to sheet metal, and convenient for subsequent
cutting work to sheet metal.
