Abstract

The invention belongs to the technical field of cutting for amorphous alloys, and specifically relates to a quasi-continuous laser drilling and cutting process for an amorphous alloy. The quasi-continuous laser drilling and cutting process for the amorphous alloy comprises the following steps: fixing the amorphous alloy to be cut to a fixture at first, and then drilling and cutting a part to be cut, of the amorphous alloy, through quasi-continuous laser under the protection of cooling inert atmosphere. According to the quasi-continuous laser drilling and cutting process for the amorphous alloy, the amorphous alloy is drilled and cut through the quasi-continuous laser, input heat is low, and the amorphous alloy at a cutting joint is not crystallized, so that an adverse effect on the performance of a material at the cutting joint is avoided; and a groove is formed in the fixture, slag generated in a drilling and cutting process can be smoothly blown out instead of being left at the cutting joint to form adhering slag or burrs, the depth of the groove is greater than or equal to 10mm, and the slag can be effectively prevented from splashing and being attached onto the amorphous alloy,so that reduction for aftertreatment procedures is benefited, and the production efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of cutting amorphous alloys, and in particular relates to a quasi-continuous laser drilling and cutting process for amorphous alloys. Background technique [0002] Amorphous alloys are formed by ultra-rapid cooling and solidification of molten metals. Since the atoms do not have time to arrange and crystallize in an orderly manner when the alloy is solidified, the obtained solid alloy has a long-range disordered structure. There are no grains and grain boundaries of crystalline alloys, and the atoms are arranged It is more compact, has excellent magnetic properties, corrosion resistance, wear resistance, and also has very high strength and hardness. However, amorphous alloys also have high brittleness. Due to its high hardness and brittleness at the same time, it also brings challenges to the cutting process of amorphous alloys. [0003] Existing cutting technologies include mechanical cutting, wire cuttin...
