Title:
FORGING METHOD AND FORGING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/146322
Kind Code:
A1
Abstract:
The present invention relates to a forging method and a forging apparatus, capable of: reducing the amount of tray plates used during the forging of materials by reducing the width from front to back of the tray plates by fixing only the rear of the materials to the tray plates for fixing the materials; and minimizing the amount of materials used, by compression-molding products by fixing, to the tray plates, the materials having a minimum size necessary for the final products, the present invention comprising: a press having upper and lower molds; a tray plate supply means for supplying, to the top rear 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 rear top of the 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 rear 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.
