Abstract

The invention relates to the field of surface pattern processing of bulk amorphous alloys, in particular to a rapid processing device for a bulk amorphous alloy surface pattern. The device comprises amold, a pressing mechanism and a heating power source, wherein the mold and a bulk amorphous alloy are respectively connected with a positive electrode and a negative electrode of the heating power source through wires for heating the bulk amorphous alloy; the mold is fixedly arranged on the pressing mechanism, and is used to press the mold on the surface of the bulk amorphous alloy at a set pressure through the pressing mechanism and stamp to form a required pattern on the bulk amorphous alloy. According to the utility model, through the arrangement that the mold is pressed on the surface ofthe bulk amorphous alloy through the pressing mechanism, and electric heating is carried out, so that a part to be processed of the bulk amorphous alloy quickly rises to above the glass transition temperature, and after softening, the required pattern is formed under the pressure of the mold, the processing speed is fast, the efficiency is high, the heating time is short, no scrap is generated, and an amorphous structure is not affected.

Description

technical field [0001] The invention relates to the field of surface pattern processing of bulk amorphous alloys, in particular to a rapid processing device for surface patterns of bulk amorphous alloys. Background technique [0002] Amorphous alloy is solidified by ultra-rapid cooling. When the alloy is solidified, the atoms have no time to arrange and crystallize in an orderly manner. The obtained solid alloy has a long-range disordered structure. The grains and grain boundaries of the state alloy exist. This amorphous alloy has many unique properties. Due to its excellent performance and simple process, it has become the focus of research and development in the field of material science at home and abroad since the 1980s. [0003] In the mass production process of bulk amorphous alloys, various specific patterns, such as brand logos and pattern patterns, are usually processed on the appearance surface according to requirements. At present, commonly used processing metho...
