Description of stretch bending process parameters for super group white steel doors and windows

Date:2015-05-13 Author: Click:

Super group white steel doors and windows to talk about stretch bending process parameters. The key to stretch bending process is to choose the appropriate machining parameters for stretch bending process. In addition to the relatively small changes in dies and other factors, the process parameters affecting the quality of stretch bending include stretch force, deformation and so on. There are two main factors restricting the processing of stretch bending in production: one is the fracture of stretch bending, the other is the excessive deformation of section size. Two aspects must be considered before determining the tension and bending parameters. In addition, minimizing elastic recovery is also an important basis for selecting the parameters of stretch bending process. In the process of drawing and bending, the unstable wrinkling phenomenon will occur if the processing parameters are not properly selected, which is also an important factor to be considered. Extruded profiles are considered as a special kind of sheet metal material. The material itself has one dimension which is much smaller than the other two dimensions. Therefore, the extruded profiles can be considered to be completed under plane stress. But the biggest difference between stretch bending and sheet metal forming is that the sheet metal is usually considered to be isotropic, while the anisotropy of extrusion profile is more obvious.
