Abstract

PURPOSE:To manufacture antivibration parts simply with an improved yield ratio, by simultaneously forming metal plates put one upon another in a press and then reforming each semiformed metal plate to the shape of adjacent metal plate. CONSTITUTION:First, two metal plates 1, 2 are put one upon another as a blank 3. For forming the bottom portion 5 of an antivibration component such as oil pan, the blank 3 is inserted in a bottom forming press 6 to undergo simultaneous forming of both metal plates 1, 2. They are then inserted in a step forming press 8 to get each metal plate formed to the shape of adjacent metal plates 2, 1 with a step 7 to produce oil pans 10. Numbers 11, 12 in the drawing represent dies, 13, 14 represent punches and 15, 16 represent blank holders.
