Abstract
PURPOSE:To prevent the sticking of an aluminum onto a die bearing face and to improve the surface roughness of a pipe stock by using ceramics as the component material of the die for ironing. CONSTITUTION:The thickness of a pipe stock is thinned by ironing by passing a die 1 by engaging the tip of a punch 3 with the bend part 2a formed on one end of the pipe stock 2 by curling. A ceramics is used as the component material of this ironing die. There are partially stabilized zirconia formed by adding a stabilizing agent of specified concentration to ZrO2, silicon nitride, alumina, sialon, etc., as for the ceramics. By using these ceramics, the die wear is reduced, the die life is extended, the use of a low viscosity lubrication oil is enabled and the consumption of oils can be reduced.
