The invention provides a corner drawing forming and both edge correcting device. The corner drawing forming and both edge correcting device comprises a lathe body and a pressing device arranged on the lathe body, wherein the pressing device comprises a pressing hydro-cylinder and a pressing plate which are mounted on the lathe body, and the lathe body is also provided with an axle-type fast-change forming device and an integrated type shearing device. The axle-type fast-change forming device comprises a multi-station axle-type forming roller, a forming guiding pulley, a forming groove positioning driven pulley and a multi-station transformation reshaping combined square die upper die, and the integrated type shearing device comprises a shearing adjustment wedge, a shearing cutter, a shearing cutter seat, a shearing hydro-cylinder and a both edge correction reshaping hydro-cylinder. The shearing cutter is mounted on a rolling die rack, the shearing cylinder is mounted on a slider back board, and the both edge correction reshaping hydro-cylinder is mounted under a combined square die seat. The corner drawing forming and both edge correcting device has the advantages that a forming groove is convenient and rapid to change, the shearing efficiency and the shearing quality are greatly enhanced, the utilization rate of a combined square die is increased significantly and the like.
