FORGING METHOD AND FORGING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2017/146329

Kind Code:

A1

Abstract:

The present invention relates to a forging method and a forging apparatus, capable of simultaneously molding two products at the front and rear of materials and thereby increasing the productivity of compression molding, the present invention comprising: a press having upper and lower molds; a tray plate supply means for supplying, to the top center of the lower mold, tray plates to be vertically movable from one side to the other side by a pitch and to be spaced from the upside of the lower mold; a punching unit provided at one side of the upper and lower molds so as to continuously punch material fixing hole parts in the tray plates; a material plate supply means provided at the front of the other side of the punching unit so as to supply material plates by a pitch to under the material fixing hole parts of the tray plates and, at the same time, form penetrating protrusion parts, which penetrate into the material fixing hole parts, on the center top of each material plate in each pitch, which is moved by a pitch; a cutting and compressive fixing unit provided on the upper and lower molds at the other side of the punching unit so as to cut the material plates, which are inserted into the material fixing hole parts of the tray plates, by a pitch and, at the same time, allow the penetrating protrusion parts formed at the center of the cut materials to penetrate into the material fixing hole parts, thereby compressively fixing same; and a compression molding unit provided on the upper and lower molds at the other side of the cutting and compressive fixing unit so as to compression-mold the materials being transferred.
