Titel
Fundamental investigation of the "Draw-peeling" process
Abstract
With the production of wire rod, partially unavoidable errors in the boundary region develop. For that reason, wires for qualitative-fastidious products all over the world undergo a cutting treatment today. One of these procedures is draw-peeling. So far a closed view of the process is missing and in addition to that, a multiplicity of explanatory variables affects the result, which can lead again to further errors. The consequence is that during the optimisation of this process, a high number of empirical tests are necessary. Based on this consideration, the present essay shows an approach by using the finite element method to reduce that complexity. On the basis of 2-dimensional calculations with different friction factors (100Cr6) and experimental tests with constant boundary conditions we created a first basis for the optimization of the draw-peeling. Calculations could be compared with the test results by using a force measurement and a high speed camera which documented the cutting process for the first time.
