The invention discloses a
sheet metal stamping device. A cylinder rod of an air cylinder is connected to the left side of a movable frame, a first bracket is arranged on the right side of a support column, a first motor is installed at the bottom of the first bracket, a second
threaded rod is connected to an output shaft of the first motor, a first threaded sleeve is in threaded connection to theouter side of the second
threaded rod, and the first threaded sleeve is fixedly connected with the outer side of a movable
barrel. According to the
sheet metal stamping device, a plurality of stampingsupport seats are arranged, so that different shapes of sheet
metal pieces of different sizes can be positioned, supported and clamped by the device, the different sheet
metal pieces are convenientlystamped, and the
stamping precision of the sheet
metal pieces is increased; according to the
sheet metal stamping device, a
stamping head is brushed by a first
bristle brush wheel and a second
bristle brush wheel, and brushed chippings are sucked by a hollow plate, so that the
stamping head is kept clean, the rate of finished products of the sheet metal pieces is increased, and the surfaces of the sheet metal pieces are prevented from being scratched and damaged by the chippings.
