Abstract

PURPOSE:To reduce processing time of the work and cost by working divided interrelated parts under being connected state and then separting them. CONSTITUTION:External shape of bottom plates 3a and 3b is blanked in the external shape blanking process, and fitting holes 4, 4 and 5, 5 are formed on the outer periphery of bottom plates 3a, 3b. When necessary, vent holes 6 and 6 are formed in the bottom plate 3b. In drawing process, bottom plates 3a and 3b are drawn to form specified shape. In separating process, bottom plates 3a and 3b are cut and separated. Since bottom plates 3a and 3b are manufactured by press working at the same time and in parallel using ne die, working processes are reduced remarkably.
