    • A pneumatic marking tool (35,123) is attached to one of the punch mounting holes (9) of the upper turret disk (3) of a punch press. When the punching striker (13) is moved down to its lower dead point, compressed air is supplied from a compressed air supply unit (103) to the marking tool to move the marking stylus (49, 129) up and down repeatedly at a high speed. At the same time, the work (W) is moved in a two-dimensional way by the Y- and X-axis work driving mechanisms (27, 29) of the punch press, in synchronism with the repetitive marking stylus motion, to engrave characters and/or symbols as a form of gathered dots all under control of the numerical control unit (33). Therefore, it is possible to mark or engrave any required characters and/or symbols without occupying a number of punch mounting stations of the upper turret disk and without the use of any punch press of high punching frequency, thus eliminating the laborious setting work required whenever the plate thickness of the work changes.
    • 气动打标工具(35,123)安装在冲压机的上转塔盘(3)的一个冲头安装孔(9)上。 当冲压冲头(13)向下移动到其下死点时,压缩空气从压缩空气供应单元(103)供应到标记工具,以将标记触针(49,129)反复地上下移动 速度。 同时,工件(W)通过冲压机的Y轴和X轴工作驱动机构(27,29)以二维方式与重复标记触针运动同步地移动,以雕刻 字符和/或符号作为数字控制单元(33)的控制下的聚集点的形式。 因此,可以标记或雕刻任何所需的字符和/或符号,而不占用上转塔盘的多个冲压安装台,并且不使用高冲压频率的任何冲压机,因此消除了每当需要费力的设置工作 工作板厚度变化。
