    • A punch press which has an X-Y guidance system for moving the workpiece relative to the workstation also includes means for rotating the workpiece on the worktable upon release of the workpiece from the X-Y guidance system. In this fashion, the workpiece may be rotated into a reoriented position and then reclamped in that position within the X-Y guidance system. This press includes a tool mounting means on the head of the press and means for effecting reciprocal motion of the tool mounting means along a vertical axis and rotation of the tool mounting means about that axis. Generally, the press will also include a die assembly in the base which includes at least a portion which is rotatable about the same vertical axis so that the workpiece when gripped therebetween may be freely rotated in a fixed clamped position to effect the desired reorientation. The tool mounting means may comprise the punch mounting mechanism, or the stripper mounting mechanism, and the entire lower portion of the ram assembly may be rotatable, or only the stripper assembly.
    • 具有用于相对于工作台移动工件的X-Y引导系统的冲压机还包括用于在从X-Y引导系统释放工件时将工件旋转在工作台上的装置。 以这种方式,工件可以旋转到重新定向的位置,然后在X-Y引导系统内的那个位置被重新放大。 该压机包括在压头的工具安装装置和用于实现工具安装装置沿垂直轴线的往复运动和工具安装装置围绕该轴线旋转的装置。 通常,压机还包括在基座中的模具组件,其包括至少一个可围绕相同垂直轴线旋转的部分,使得夹紧在其间的工件可以在固定的夹紧位置自由旋转以实现所需的重新定向。 工具安装装置可以包括冲头安装机构或剥离器安装机构,并且冲头组件的整个下部可以是可旋转的,或者仅可以是汽提器组件。
