Abstract

A multi-forming method is disclosed. A multi-forming method according to an exemplary embodiment of the present invention may include a first material supply step in which a sheet is loaded on a lower mold and a blank holder; a material warm-heating step in which an upper mold is lowered to grasp an edge of the sheet together with the blank holder, and the sheet is heated to a warm-forming temperature; a warm-forming step in which the upper mold is combined with the lower mold and plastic-deforms the sheet to a maximum deformation depth of a product in the warm-forming temperature; a plastic superplasticity heating step in which the sheet is unloaded from the warm-forming mold and is heated to the superplastic temperature; a secondary material supply step in which the sheet is loaded through a cushion spring corresponding to circumference of the lower mold; a blow-sealing step in which an upper mold grasps an edge of the sheet together with the blank holder, and a sealing bead formed along an edge circumference of the lower mold of the blow-forming mold and blowing gas is supplied into a gap between the lower mold and the sheet so that the sheet is deformed to a final shape of a product; and a product unloading step in which the upper mold is separated from the lower mold to unload a final product.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0188959 filed in the Korean Intellectual Property Office on December 29, 2015, the entire contents of which are incorporated herein by reference. [0003] Background of the invention [0004] (a) Field of Invention [0005] The present invention relates to a multi-froming method. More particularly, the present invention relates to a multi-forming method in which one mold set performs warm forming and blow molding having temperature conditions different from each other to produce a product having a complex formed shape and a large forming depth. [0006] (b) Description of related technologies [0007] In general, warm forming processes have been developed to stamp magnesium alloy sheets of lightweight materials, where the density of the metal structure is less than that of aluminum alloy sheets, and in the United States, warm forming...
