A punching device for evaluating formability according to the present invention includes a device body, a punch punching a material, and a forming unit formed on the device body to replace the punch automatically. As the punching device for evaluating formability includes a rotary unit automatically replacing the punch on the forming unit and an attaching-and-detaching unit attaching and detaching the punch to be replaced to/from a punching cylinder, the punch can be automatically replaced without a manual task of a worker. Therefore, the punching device for evaluating formability reduces the risk of accidents by a worker and time for setting the punch. Furthermore, the accurate result of evaluating a formed degree can be obtained by accurately setting the punch. |
