Problems solved by technology

However, the traditional preparation process generally requires large-scale thermomechanical processing equipment, such as extrusion equipment, forging equipment, etc., to perform thermomechanical processing on the preform after casting. For large-sized parts, thermomechanical processing still has uneven deformation. Problems causing uneven organization and performance
[0003] Incremental forming technologies such as electron beam and laser forming can also be used to prepare metal structural parts. Generally, fuses, melting powder, and cladding after powder spreading are used to realize the forming of parts, but parts formed by electron beam and laser are generally The as-cast structure is difficult to control through subsequent heat treatment, and some of the defects are difficult to bridge through subsequent heat treatment

Abstract

The invention relates to a forming method of an irregular steel component, belonging to the technical field of mechanical machining. The forming method comprises the steps of firstly thermally machining a prefabricated blank to obtain a metal strip, preparing a steel component prefabricated blank in a certain shape layer by layer through a stirring, connection and combination method, and machining and surfacing the steel component prefabricated blank to obtain a steel component. The thermal machining method of the strip can be a forging method, an extruding method and a rolling method and also can be a combined method of the forging method, the extruding method and the rolling method. Due to the adoption of the forming method, the requirement on the equipment is lowered, and even a large-sized component does not need a large-sized thermal machining device; the prepared irregular steel component is enabled to have a better mechanical property; moreover, the utilization rate of the material is high, and the working efficiency is increased; and the forming method can be used for preparing a metal-based composite material with enhanced particles and even the metal-based composite material with an enhanced carbon nanotube, thereby having a wide application prospect.

Description

technical field [0001] The invention relates to a forming method of irregular steel parts, which belongs to the technical field of mechanical processing. Background technique [0002] When preparing metal structural parts, such as high-strength steel structures, in order to prepare high-performance parts, it is often necessary to perform thermomechanical processing on the cast structural parts, such as extrusion, forging, rolling and other thermomechanical processing, so that they can be broken Coarse original as-cast grains refine the structure, resulting in high-performance structural parts. However, the traditional preparation process generally requires large-scale thermomechanical processing equipment, such as extrusion equipment, forging equipment, etc., to perform thermomechanical processing on the preform after casting. For large-sized parts, thermomechanical processing still has uneven deformation. Cause the problem of uneven organization and performance. [0003] ...
