Abstract

The application provides a method for forming a metal stepped piece using a viscous medium and a forming die set. Wherein, the method includes: first manufacturing a preform with a first step, and then forming a second step on the first step of the preform by using a viscous medium pressure forming method through the first concave die and the floating die. In the method provided by this application, the viscous medium can simultaneously form non-uniform pressure and tangential adhesive adhesion stress on the surface of the sheet, and the tangential adhesive adhesion stress increases the shear stress in the thickness direction of the sheet, avoiding local thinning of the wall thickness during forming, and ensuring The uniformity of the wall thickness after the deformation of the plate is ensured, and the purpose of controlling the change of the plate thickness and avoiding local thinning is achieved. In addition, through the two-time forming scheme, the shape error caused by one-time forming is avoided, and the diversity of products with complex cross-sectional features is increased.

Description

technical field [0001] The present application relates to the technical field of viscous medium pressure forming, in particular to a method for forming a metal stepped piece using viscous medium and a forming die set. Background technique [0002] The shape of the aluminum alloy stepped part is complex, and the plasticity of the aluminum alloy material is low, which brings difficulties to the forming of the part. During forming, the area with large local deformation is prone to excessive thinning or even cracking defects. As a soft molding method, viscous medium forming can effectively control the flow of materials by adjusting the pressure distribution, realize the control of the deformation sequence of the sheet metal, improve the formability of the sheet metal, achieve the control of the thickness change of the sheet metal and avoid local thinning Purpose. For aluminum alloy stepped parts, which have poor plastic deformation ability and complex shapes, only relying on vi...
