Method for producing e.g. die utilized for producing ultra-high-strength structural components in passenger car body, has optimizing contact surfaces, and producing tool with optimized tool geometry by machining process

摘要

#CMT# #/CMT# The method involves performing computer-aided construction of a sheet metal component (6) to be produced and tool geometry that corresponds to the component. Contact pressures between the tool geometry and component are computed, and contact surfaces are optimized so that uniform contact pressure arises between the tool geometry and component. The tool geometry is formed by tool inner surfaces (5) that are optimized by simulation of thinning and thickness increase at the component. A shaping tool (1) is produced with the optimized tool geometry by a machining process. #CMT#USE : #/CMT# Method for manufacturing a shaping tool e.g. hot-shaping tool (claimed) such as die and male mold, that is utilized for producing ultra-high-strength structural components in a passenger car body. #CMT#ADVANTAGE : #/CMT# The method enables production of the shaping tool with optimized drawing gap and/or tool inner surfaces while achieving increased production accuracy of the sheet metal component. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating operation of a method for producing a shaping tool. 1 : Shaping tool 2 : Upper tool 3 : Lower tool 5 : Tool inner surfaces 6 : Sheet metal component.
