The invention relates to a stamping and forming all-in-one machine, in particular to a self-discharging type stamping and forming all-in-one machine. The self-discharging type stamping and forming all-in-one machine can achieve automatic feeding, can continuously work, can save time, is easy and convenient to operate and can also avoid stamping accidents. The self-discharging type stamping and forming all-in-one machine comprises a chassis, a rack, an arc-shaped plate, a supporting column, an L-shaped block, a motor and the like. The rack, the supporting column and the motor are fixedly arranged on the chassis, the rack is located on the right side of the supporting column, and the motor is located below the rack. According to the invention, a stamped workpiece can be pushed out through apushing mechanism, and the other workpiece in a discharging frame can be pushed into a punching frame, so that people can take down the punched workpiece, the workpiece does not need to be placed manually, automatic feeding and continuous work can be achieved, a large amount of time is saved, operation is easy and convenient, and punching accidents can be avoided.
