Abstract

1325320 Making bearings; extruding H FISHER 14 Oct 1971 [5 Dec 1970] 58125/70 Headings B3A and B3P A device for deforming blanks to produce full or half-shell bearings comprises a forming die 1, a mandrel 9, means for effecting relative movement between the die and mandrel to deform a blank when disposed therebetween, an extrusion die 2 disposed to receive a deformed blank 10 from the forming die, and means 11 for pushing the deformed blank through the extrusion die. The forming die comprises three portions 3, 4, 5 mounted on respective slides 6, 7, 8 and movable to and from the mandrel so as to deform a blank placed across the lower portion 3. A pneumatic piston and cylinder supplies the blanks to the forming die, the slides being operated by separate hydraulic rams (not shown). The extrusion die abuts the outlet end of the forming die to receive a slightly oversize deformed blank 10, thence it is fully sized. Die portions 4, 5 may be omitted for the production of part-shell bearings, and the mandrel may be arranged to move towards the die portions rather than the reverse. Either or both of the dies may be heated and the device may be used to deform both metal and plastics blanks and may operate automatically.
