Description
Technical Field
The invention belongs to the technical field of amorphous alloy micro-die production, and particularly relates to an ultrasonic imprinting forming method and forming equipment of a high-temperature high-strength amorphous alloy micro-die.
Background
There is a great need in the fields of aerospace, armamentarium, information communication and advanced manufacturing for optical glass elements such as aspherical lenses, microlenses and the like, and precision press molding is a leading-edge technique for manufacturing such elements. The press molding temperature of optical glass is usually 500 ℃ or higher, for example, the glass transition point of BK-7 is about 650 ℃, which requires the press mold to maintain high hardness and strength, surface finish, thermal stability, abrasion resistance and chemical stability at high temperature to cope with multiple adverse effects of complex stress, cold and hot cycles, corrosive environment and the like during high temperature service.
Typical mold materials in the prior art, such as tungsten carbide, silicon carbide, etc., require some precious metal alloy films or metal nitride films to be plated on the surfaces to prevent adhesion between the mold and the glass. However, these mold materials are typically hard and brittle materials, which are difficult to process, and the coating process makes the mold expensive to manufacture.
The amorphous alloy has the advantages of uniform structure, high strength, high hardness, abrasion resistance, small thermal expansion coefficient, atomic surface finish and the like, and is an ideal material for preparing high-precision mould pressing dies. However, the traditional amorphous alloy has low glass transition temperature, poor high-temperature strength and thermal stability, so that the service temperature is difficult to exceed 500 ℃, and the requirement of the existing optical glass compression molding temperature cannot be met.
In addition, the traditional micro-die processing means mainly comprise means such as single-point diamond turning, ultra-precise grinding and the like, but the techniques cannot be applied to the processing and forming of Ir-based high-temperature and high-Jiang Fei crystal alloy, because the ultrahigh strength and the ultrahigh hardness of the Ir amorphous alloy can cause the damage of a cutter, and in addition, the intrinsic brittleness of the amorphous alloy can cause the failure of amorphous alloy parts during processing. At present, thermoplastic forming is a better scheme for solving the micro-machining problem of an Ir-based amorphous alloy die, but too high forming temperature (the glass transition point is as high as 820 ℃) has strict requirements on the tolerance, the vacuum degree and the like of thermoplastic forming equipment, so that the processing cost is higher, and the processing process is more complicated. Meanwhile, as the amorphous alloy is a metastable state material, the amorphous alloy is at risk of performance degradation caused by crystallization or relaxation during thermoplastic molding, and the material reliability of the micro-die is poor.
