Thin-wall component space envelope forming buckling deformation control method

Abstract

The invention relates to a thin-wall component space envelope forming buckling deformation control method. The method comprises the following steps: S1, establishing a rectangular coordinate system; S2, the envelope center O1 of the envelope model being on the z axis, and the distance between the envelope center O1 of the envelope model and the coordinate origin O being H; S3, enveloping die cone point offset being carried out; S4, designing a main body part of the envelope model; S5, designing the front end part of the envelope mode; S6, optimizing process parameters; and S7, thin-wall component space envelope forming buckling deformation control being carried out. In the space enveloping forming process of the thin-wall component, plastic deformation with the wall thickness reduced and the diameter increased occurs, a contact area of a main body part of an enveloping mold and a blank is located on one side of a center shaft, a contact area of the front end part of the enveloping mold and the blank is located on the other side of the center shaft, and therefore space enveloping forming buckling deformation control over the thin-wall component is achieved. According to the method, accurate control over the spatial envelope forming buckling deformation of the thin-wall component can be achieved, and then the spatial envelope forming precision and the yield of the thin-wall component are improved.

technical field [0001] The invention relates to the field of manufacturing thin-walled components, in particular to a method for controlling warping deformation of thin-walled components in space envelope forming. Background technique [0002] Thin-walled components are key components of high-end equipment and are widely used in aircraft, spacecraft, ships, etc. Thin-walled components have harsh service conditions and high assembly requirements, which put forward strict requirements on the mechanical properties and precision of thin-walled components. At present, the main manufacturing method of thin-walled components is mechanical processing, which can manufacture high-precision thin-walled components, but the streamline of thin-walled components is destroyed, and the performance of thin-walled components is difficult to guarantee.

Problems solved by technology

However, the thickness of thin-walled components is small, and warping and deformation defects are easily generated during the space envelope forming process, resulting in a decrease in the forming accuracy and yield of thin-walled components
