VACUUM WELDING APPARATUS OF NON-FERROUS ALLOY

摘要

PURPOSE: An automated vacuum welding apparatus of non-ferrous alloy is provided which is a help to mass production of a spectacles frame by easily welding a construction member such as the spectacles frame consisted of non-ferrous alloy. CONSTITUTION: In a cartridge (A) which is mounted on a vice on a table that is installed inside a vacuum chamber, the vacuum welding apparatus of non-ferrous alloy is characterized in that the cartridge (A) comprises a bridge fixing die(20) on which inserting grooves(20a) are formed so that a plurality of bridges for spectacles frame(24) that are an object to be welded are inserted into the inserting grooves(20a) in multistage; and rim fixing dies(21) into which a plurality of rims for spectacles frame(23) are received in multistage, on which projecting parts(21b) and female grooved parts(21a) are formed so that the rims(23) are coupled onto the female grooved parts(21a), and to upper and lower parts of which bolts(21c) are screw connected to adjust a gap according to dimension of the rims(23).
