Laser molding method of extra/ultra high-voltage circuit tool

Abstract

The invention relates to a laser molding method of an extra / ultra high-voltage circuit tool. The molding method comprises the steps of: cleaning of the surface of a material; preheating of a worktable; placement of a titanium alloy; laser irradiation; rolling of a forging wheel; molding of a test piece; and cooling of the test piece. The laser molding method adopts the laser to melt a filament with a special metal material, melts a microlayer, is superior to a quenching process in performance, easy to operate and lower in cost, and improves the mechanical performance and refines crystallized particles through a layer-by-layer quenching process; protective gas is introduced, so that a protection structure is not oxidized, and microelements can be molten in molding; the laser molding method solves the defect that the technical performance of a general laser cladding technology cannot superior to that of a forged piece; the metal is leveled and forged in the melting and cooling process; different scanning methods are selected for different areas, so that the strain deformation and cracking problems caused by the heat concentration are effectively prevented; and the laser molding method is high in controllability and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of component manufacturing, and in particular relates to a laser forming method for ultra-high voltage line tools. Background technique [0002] After the birth of the world's first laser in 1960, lasers have been widely used in various industries, especially in the industrial field. Laser technology is a comprehensive technology involving many disciplines such as light, mechanics, electricity, materials and testing. Using the interaction between laser beams and substances, materials can be cut, welded, surface treated, drilled and micro-processed. [0003] Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance. In the 1950s and 1960s, high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes were mainly developed. A batch of corrosion-resistant titanium alloys were develo...
