Technical Field

The invention belongs to the technical field of laser additive manufacturing, and particularly relates to a method for preparing a complex thin-wall component by adopting laser metal deposition and follow-up rolling.

Background

With the progress of aerospace technology, in order to meet the development requirements of high mach number, high performance and high reliability of new generation aerospace vehicles and engines thereof, the requirements of light-weight high-temperature-resistant complex thin-wall components are continuously increased, and because different use conditions are met, the shapes, the wall thicknesses, the material types, the mechanical properties and the like of the thin-wall components have great differences, and the manufacturing methods are different. In the air intake and exhaust system of the advanced warplane, there are complex thin-wall metal components with complex shapes, ultra-thin wall thicknesses and extremely high precision requirements. For example, an air inlet channel in an air inlet system and an exhaust channel in an exhaust system have complicated and changeable section shapes and bending axes in order to meet specific aerodynamic performance and stealth performance, and titanium alloy and high-temperature alloy thin-wall plate blanks are mostly adopted in the components. Because the traditional rigid die stamping cannot apply effective and reasonable forming load to all parts of the blank, the blank is often manufactured by a method of stamping and forming in blocks and then welding, particularly to a component with negative curvature or a component with a closed section. However, due to the springback of the press forming, the shape accuracy of the blank is difficult to control, and the subsequent tailor welding of a plurality of blanks causes complex deformation, so that the combined action of the two reduces the dimensional accuracy of the part. Meanwhile, the total length of the welding line is large due to the large number of the parts, and the reliability of the parts is greatly reduced. If a large number of curved surface thin-wall rib plates exist on the carrier rocket, the member is usually manufactured by a roll bending or press bending method, and in order to reduce the structural weight, a subsequent material reducing processing technology is usually adopted to cut and remove a local area. However, the problems of distortion of the thin-walled member, excessive local processing, and instability of the bead tend to occur during the cutting process.

In order to solve the above problems in the manufacture of large-sized complex-shaped thin-walled tubular/plate-shaped members, a laser metal deposition 3D printing technique has been introduced, which prepares a metal member by layer-by-layer deposition by using a laser beam of higher power to generate a molten pool in a deposition region and continuously melting a metal powder material, and which can form a thin-walled metal member having a complex curvature, a large difference in section, and a bending axis. Compared with other 3D printing technologies, the forming component has larger size, higher forming speed and higher powder utilization rate, and is particularly suitable for preparing large-size complex special-shaped thin-wall components in aerospace vehicles. However, the member is easily deformed due to the influence of residual stress during the laser metal deposition process, so that the laser beam cannot be applied to the end face of the member, and continuous printing of the thin-walled member cannot be performed. For the formed thin-wall metal component, mainly from two aspects of precision and performance, hot isostatic pressing densification treatment is usually required after the metal component is prepared by laser metal deposition to eliminate micro-cracks, pores, non-fusion defects and the like on the surface and inside of the formed component. However, in the laser metal deposition technology, metal powder is melted by using a laser beam with high power (1000 w-3000 w), and the height of a single-layer deposition layer is more than 0.1mm, so that convex-concave peaks caused by interlayer overlapping appear on the surface of a printed component, the surface quality is poor, the convex-concave peaks cannot be eliminated even through hot isostatic pressing treatment, and the reliability of the component is greatly reduced. Therefore, it is usually necessary to machine the surface of the formed member after the hot isostatic pressing treatment to remove surface margins such as uneven peaks. However, the thin-walled member has low overall and local rigidity, and is easily affected by various factors such as cutting force of a tool, clamping force of a clamp, self structure, self internal stress and the like in the machining process to deform, so that the dimensional accuracy of the member is reduced.

In order to reduce the problem of the convex-concave peaks caused by the interlayer overlapping existing in the process of preparing the component by laser metal deposition, people begin to apply the laser polishing technology to polish the metal component formed by 3D printing, and the principle is that a laser beam is applied to the convex-concave peak area on the surface of the formed component, so that the peak on the surface is melted, and the melted liquid metal is redistributed into the concave pits to smooth the original surface. The surface topography after final polishing depends primarily on the parameters of the laser beam applied to the surface of the forming member and the initial topography of the surface of the forming member. Although the method can improve the initial appearance of the component and improve the surface integrity, the laser polishing process is a remelting process, which is equivalent to secondary forming of the surface of a thin-wall component, and the thin-wall component is inevitably deformed under the influence of temperature gradient, so that the dimensional accuracy of the component is reduced.

In order to solve the problems that the laser beam cannot act on the end face of a component due to the deformation of the component caused by residual stress when a complex special-shaped thin-wall component is prepared by the existing laser metal deposition technology, so that the continuous printing of the thin-wall component and the surface of the formed component cannot be finished, the surface quality is poor, the reliability is reduced due to the convex-concave peak caused by the interlayer lap joint, and the secondary deformation is easily caused when the surface of the component is subjected to mechanical processing or laser polishing treatment, a new preparation method of the complex thin-wall component needs to be developed.
