Technology Strategies of Bending Forming for Part of Large Size and Ultra Thin-Walled

Article Preview

Abstract:

In this paper, on the basis of bending forming force and deformation analysis for a stainless steel part in a precision instrument, the combination mould having filling and support function is designed for the part with large size, ultra thin-walled and non-closed cross section structure characteristics. Combined with the forming process, the technological measures are proposed to eliminate the bending forming deformation by using the way of incremental forming control and the gap control between mould and part. And the forming process and the reliability are verified by the practical application.
