Abstract

A hydroforming device for manufacturing U-shaped products with the advantage of improving product quality includes: a lower base; a lower mold, which is installed on the lower base and is provided with a U-shaped lower cavity; an upper mold, which is provided with a lower The cavity corresponds to the U-shaped upper cavity and is combined with the lower mold; the upper base is installed on the upper mold and combined with the lower base; and an adjustment unit for adjusting the U-shaped upper and lower cavities.

Description

[0001] Cross-references to related applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2006-0110043 filed in the Korean Intellectual Property Office on November 8, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a hydroforming device for producing U-shaped products. More particularly, the present invention relates to such a hydroforming device for manufacturing U-shaped products, which has the advantage of improving product quality by adjusting the shapes of U-shaped cavities of upper and lower molds. Background technique [0004] refer to Figure 10 , the process for manufacturing U-shaped products will be specifically described. [0005] Such as Figure 10 As shown in , when the tube is bent into a U-shaped tube, the U-shaped tube is freely formed into a U-shaped rough product. After that, the hydroforming process is performed by applying hydrau...
