摘要:
A press formed product is disclosed. A method for manufacturing the press formed product is a method for manufacturing the press formed product including applying press processing including stretch flange forming to a single metal sheet of one sheet material after performing shearing processing of the metal sheet to manufacture the press formed product. When a region where a stretch flange crack is estimated to be likely to occur when the single metal sheet is press formed by the press processing is set as a stretch flange crack region, the press processing is applied after heating and cooling the end surface of the metal sheet positioned in the stretch flange crack region and at least the end surface in the end surface and the vicinity thereof in the single metal sheet after the shearing processing.
摘要:
An apparatus for trimming a sheet metal panel in a die set. A grinding tool including a grinding wheel driven by a rotary drive is used to grind away a shear affected zone from the trimmed edge formed by the trim steel. The grinding tool is disposed within a cavity defined by the reciprocating die and is oriented to grind away a shear affected zone as the reciprocating die moves the grinding tool into engagement with the trimmed edge.
