Abstract
1,252,875. Casting processes; making rocker arms. DR.-ING. h.c.F. PORSCHE K.G. 4 June, 1970 [11 June, 1969], No. 27055/70. Headings B3A and B3F. [Also in Division F1] Castings 1, e.g. rocker arms, having bearing bores 4 are manufactured by casting iron into a mould containing a sheet steel chill or core 8 to form a bearing bore having a surface region 4 with a ledeburitic structure. In order to control the rate of cooling by the chill or core 8, the chill or core may be preheated, precooled, may be force-cooled by passing coolant through its central bore during cooling of the casting or may be coated with a heat-insulating layer. Several articles may be cast in one mould, the core or chill being formed by one pipe which extends through a number of mould cavities to form a bearing bore in each casting. The core or chill 8 may be removed by turning or in the case of a throughbore by pressing out. The bearing bore is ground to its required final size.
