Abstract
998,287. Extruding; forging; making spark plug casings. ROBERT BOSCH G.m.b.H. Jan. 18, 1963 [Jan. 18, 1962], No. 2304/63. Headings B3A, B3H and B3P. A hollow shouldered article 2, such as a screw closure or spark plug casing, having a partly solid foot 2c, a hollow cylindrical portion 2a and an enlarged head 2b is made by placing a blank 1 cut from cylindrical stock in a die cavity 4 of the desired external shape and pressing it in a single stroke by a punch 26 having a nose end 38 and which is surrounded by a guiding sleeve 41 whose end 42 fits the die cavity 4a, the foot 2c being formed by forward extrusion, the head portion 2b by transverse flow and the centre portion 2a by backward extrusion. The cold blank sheared from bar stock and lubricated, is inserted in the die which comprises three parts 3a, 3b, 3c clamped together on a base 6 by an outer ring 5 and screws 13. An ejector pin 23 closes the bore of the die cavity and also forms a recess in the foot 2c. To assist sealing of the die parts they are in contact only over a small inner annular area. Die cavity 4a is of hexagonal cross-section to provide a hexagonal head 2b on the spark plug casing. Punch 26 has guiding lands 36, 39 slidable within the sleeve 41 and is clamped by ring 31 and screws 34 to an upper platen 29 fixed to the press ram. Sleeve 41 has limited movement relative to the punch and is connected by rods 45 to a cross-head 48 upon which an adjustable downward pressure P is applied through rod 49 and lever 52. This pressure may be hydraulic or produced by springs or weights. During the retraction stroke of the punch, the downward pressure P on the sleeve acts to strip the workpiece from the punch. If this does not occur the sleeve is also retracted and its lever 52 engages a switch 53 which stops the press. Finally, the foot 2c is pierced and threaded externally and the centre part is knurled.
