Shear deformation device for scalping

Abstract

The present invention relates to a shear deformation device. To improve the productivity by solving the problem that the amount of shear deformation of a material is not uniform and sufficient due to the gap between the curved portion of the molding path and the lower parts of the material and omitting any additional process for removing irregularity and surface products on the surface of the material, there is provided a shear deformation device capable of scalping, characterized in that a scalping guide path which allows the surface of the material to be separated from the other portions of the material as the material is scalped at a predetermined thickness when passing through the curved portion during shear deformation is formed in the curved portion in communication with the molding path. In addition, there are provided additional constructions for effectively performing shear deformation by a small power by reducing the friction at the molding path excepting the curved portion. The present invention thusly constructed can be utilized for continuously and effectively mass-produce sheared materials.
