A flow type hydraulic forming machine which reduces the manufacturing cost and maximizes the spatial efficiency by allowing a single apparatus to perform a forming process of short aluminum cups in multiple steps, thereby extending the length of the aluminum cups and producing aluminum cups with various lengths along respective steps is provided. A flow type hydraulic forming machine comprises: first to third hydraulic cylinders(11-13) installed in parallel and respectively connected to a hydraulic unit(8) installed at one side of an upper part of a frame(5); and first to third forming parts(41-43) installed in parallel to form aluminum cups by punches(21-23) and dies(31-33) operated by the hydraulic cylinders, thereby extending the length of the aluminum cups, wherein the first to third forming parts form the aluminum cups such that the aluminum cups are extended stepwise by the punches and the dies of the respective forming parts while formed articles of the first and second forming parts are moved and transferred to the second and third forming parts stepwise by a product transfer part. |
