Abstract
PURPOSE: To reduce the deformation of a sheet packing surface and to enable the reduction in a machine-processing cost, by a method wherein a rolled carbon steel sheet is press-punched into a given shape, bolt holes simultaneously, are perforated by a press punching process, and a sheet packing surface, which is susceptible to deform, is then pressed in stages.
CONSTITUTION: As illustrated in the drawing, a rolled carbon steel sheet blank is formed into an external configuration 10 in a given shape, a given number of bolt holes 11 are perforated in the steel sheet by a press punching process, and a sheet packing surface 12 is then pressed in a stage to form a case cover. A numeral 13 in the drawing represents the part which is pressed in stages. As noted above, a case cover 9 is formed such that, after the external configuration 10 for the case cover and the bolt holes 11 are punched, the sheet packing surface 12, which is susceptible to deform, is pressed in stages. As a result, the sheet packing surface 12 is reduced in deformation, and this reduces a machine-processing cost and enables the sharp reduction in its manufacturing cost.
