Abstract

1469774 Cross wedge rolling MITSUBISHI JUKOGYO KK 19 March 1975 [17 Jan 1974 2 May 1974] 2289/74 and 9221/75 Heading B3M Cross wedge rolling apparatus which is suitable for rolling a cylindrical component 7, Fig. 7, with a reduced diameter central portion, comprises a pair of wedge-shaped dies each having outer bevelled surfaces of compound form. The leading end of the die, Fig. 8a, has a bevelled reducing surface a 11 -a 12 of angle α, which progressively changes in width to b 11 -b 12 , c 11 -c 12 and finally d 11 -d 12 (which is a point). As the reducing surface diminishes, a clearance surface of angle # progressively increases in width until it forms the whole of the bevelled surface. The clearance surface is not in contact with the corresponding workpiece surface (whose angle is #) and permits a greater diameter ratio d 0 /d than normal to be obtained. The dies may be carried on rolls or on flat plates.
