The invention relates to an automatic forming and shelling machine in the automation field. The machine comprises a frame, a main control electric box and a processing platform. The processing platform includes a man-machine interface control box, a lateral guiding seat, a lateral material transferring mechanism, a forming mechanism, a shelling mechanism, and a blanking mechanism. The forming mechanism includes a forming base, a pre-compression assembly and a bending assembly. The bending assembly includes a bending cylinder in an upward telescopic mode and a bending plate; the bending plate is installed at a telescopic rod of the bending cylinder and is driven by the bending cylinder to move up and down; and the upper end of the bending plate is inclined forwardly. The shelling mechanismincludes a shelling base and a three-axis mechanical arm; the three-axis mechanical arm is formed by an X moving axis, a Z moving axis, a self-rotating shaft, and a clamp. Transverse material conveying, automatic bending, automatic shelling and automatic blanking are realized; all actions are implemented continuously in order; the fully automatic operation is realized; and the work efficiency is high. Moreover, the bending effect is good and the defective product rate is low. Therefore, no additional detection mechanism needs to be set, so that the production costs are lowered.
