Automated Production Process of Laser Welded Metal Glasses Based on Powder Injection Parts

Abstract

The invention belongs to the field of production of glasses and particularly relates to a powder injection part based automatic production process of laser welding metal glasses. The process includes the steps of frame line processing, folding medium beam processing, foot processing, nose stem processing, laser welding, assembling and the like; a folding medium beam and two feet are obtained by powder injection molding, a frame line, the folding medium beam, the foot and two nose stems are respectively fixed in a laser welding combination fixture which is mounted in a laser welding machine, and the folding medium beam and two welding points of the frame line, the nose stems and two welding points of the frame line and the feet and two welding points of the frame line are subjected to laser welding; glasses legs and the feet are locked through screws to obtain a glasses frame. By the arrangement, dimensional accuracy is high, cutting processing of parts is not needed, the parts are directly molded, and automatic water grinding is adopted in part grinding; six parts can be welded at one step, and stable structure is achieved; hand polishing after welding is not needed, and welding spot processing is not needed.

Description

technical field [0001] The invention belongs to the technical field of glasses processing and relates to an automatic production process of metal glasses. Background technique [0002] Metal glasses include frame wire, feet, center beam, temples and other components. The traditional metal glasses production process: frame wire processing process is: rolling frame, milling groove, punching, grinding frame line burr; center beam processing process is: Milling the center beam, filing the center beam burr, rolling the center beam burr, and painting the center beam black; the processing process of the foot is: cutting the foot, cutting the foot R, removing the burr of the foot; the processing process of the temple is: cutting the length of the foot, Grind the feet, cut the feet, and remove the burrs of the feet; then weld the feet and hinges together to form the temples; weld the center beam on the frame line, weld the nose pads on the frame line, and then weld the feet, feet and...

Problems solved by technology

[0004] Traditional craftsmanship: manual operation of multiple processes, unstable quality, and declining profit margins of manufacturing companies as labor and material costs continue to rise

The raw materials are copper-nickel and stainless steel, which need to be polished and cut by hand, manually welded, one welding point and one process, using silver wire welding, large soldering points, manual operation, unstable structure (difficult in subsequent assembly and shaping), and consumables Many, high defect rate; welding frame polishing: after high-frequency welding, the solder joints are large and need to be polished by hand; the welding structure is unstable, and after manual polishing, the frame is easy to deform, and the frame needs to be more complicated during assembly. refurbished to meet the requirements
