Abstract
A method of manufacturing an elongate element (10) using a punching operation assumes a polynomial relationship between punch depth (dpunch) and neutral axis, with the constants being a polynomial function of plastic deformation of the beam. Using finite element analyses, a relationship between the required plastic deformation, the second moment of area of the element and the neutral axis of the element can be derived.
Claims9
A method of manufacturing an elongate component comprising the steps of:
- providing a punching apparatus configured to apply a differential contact three point bending load to the component by advancing a punch at a punch location between two supports by a punch distance,
- calculating a punch travel (dpunch) based on the second moment of inertia of the component at the punch location (Ixx), the location of the neutral axis of the component at the punch location (Y) and the required plastic deformation (dplastic) of the component at the punch location,
- bending the elongate component at the punch location by moving the punch by the punch travel (dpunch).
