Abstract
1284471 Making electrodes; stamping; spark erosion H HERTEL 17 Nov 1969 [15 Nov 1968] 56205/69 Headings B3A, B3Q and B3V [Also in Division C7] An electrode for use in electro-erosion or electro-chemical machining is made by a deforming operation using a die 11 which is a negative of the electrode. The deformation may be by rubber drawing, hydro-mechanical drawing, explosive forming, hydro-spark forming or electromagnetic forming. The electrodes for forming the upper and lower die of a tool set are made in a single operation from rolled copper sheets 12, 13, 14. The concave side of electrode 12<SP>1</SP> and electrode 13<SP>1</SP> are used as the roughening electrode and finishing electrode respectively for the upper die whilst the convex side of electrode 14<SP>1</SP> and electrode 13<SP>1</SP> are used as the roughening electrode and finishing electrode respectively for the lower die. Alternatively, a separate die 11 may be used to form a roughening and a finishing electrode for each of the upper and lower dies of the tool (Figs. 1 and 2, not shown). The shape of the formed electrode may be controlled by an intermediate layer (15) (Fig. 4, not shown). A prefabricated upper die (16) (Fig. 5, not shown) of a tool set may be used as the negative which is placed in a ring (17) and the space therebetween filled with sealing compound (18), e.g. Woods' alloy. The sheet 12 is placed on top of the ring (17) and the space therebelow evacuated during the forming operation. After shaping, the formed workpiece is removed from the ring (17) by melting the compound (18). Selected areas (22, 22<SP>1</SP>) (Figs. 7 and 8, not shown) may be removed from the electrode by a subsequent etching operation. Material may be added to the formed electrode by electrolysis or flame spraying.
