Contactless Sheet Metal Feeder for Metal-forming Machines
نویسندگان
چکیده
This paper deals with the investigation of a contactless sheet metal feeder for metal forming machines. The concept is based on an asynchronous linear motor in which the sheet metal is used as the eddy currents runner. First numerical analyses were performed by means of a parameterized finite-element (FE) model of the feeder. The focus was on the investigation of the operational characteristics in dependence on the material and geometrical properties of the sheet metal. The simulation results were validated by experiments using a demonstrator of the feeder. The results show that the feeding forces of partially above 1,000 N using the electromagnetic feeder can be doubled in comparison to mechanical roll feeders.

متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
