The utility model belongs to the technical field of sheet
metal shell
machining, and particularly relates to a
cutting device for sheet
metal shell
machining, which comprises a bottom plate, a frame is mounted in the middle of the upper end of the bottom plate, an opening and closing mechanism is arranged on the frame, limiting holes are formed in two sides of one end of the frame, and a
cutting mechanism is arranged in the frame. The two side walls of an inner cavity of the frame are each provided with an electric push rod, and the telescopic ends of the two electric push rods are each provided with a positioning block. The
cutting mechanism comprises a driving motor installed in the middle of the upper end of the frame. Through the arrangement of the
bevel gear of the cutting mechanism, the
metal plate shell can be subjected to two-section cutting work, the
machining efficiency of the metal plate shell is improved, the distance between the two sections of cutting is convenient to adjust, the cutting effect and the cutting flexibility are improved, and the machining requirement is met; and through the arrangement of a
bevel gear of the opening and closing mechanism, the
bevel gear of the frame can be shielded, so that the cutting chippings can be prevented from flying out in the cutting process, and the cutting safety is improved.
