摘要： In one exemplar embodiment, an apparatus for impressing identifying characters into the end face of metal bar stock is disclosed. A stamping apparatus operates in conjunction with conventional bar stock drawing and cutting machines. The stamping apparatus has a die positioning member adapted for pivotal movement carrying a character imprinting die that is extended and locked in the path of the moving bar stock. The force of the bar stock moving against the die imprints the identifying characters in the end face of the bar stock. Just prior to cutting of the bolt blank from the bar stock the cutting machine signals the bolt stamping apparatus and the die positioning member begins to pivot and retract into the apparatus housing thereby relieving the pressure between the end face of the bar stock and the die. The die positioning member continues to pivot into the housing as the cutting machine cuts the bolt blank from the bar stock and allows the bolt blank to fall free for collection. The bar stock is advanced again and the die positioned to repeat the imprinting process on the next bolt blank.

摘要翻译： 在一个示例性实施例中，公开了一种用于将识别字符压印到金属棒坯料的端面中的装置。 冲压装置与传统的棒材图纸和切割机一起工作。 冲压装置具有适于枢转运动的模具定位部件，该模具定位部件承载延伸并锁定在移动式棒料的路径中的字符压印模具。 棒料向模具移动的力在条形件的端面上印出识别字符。 在从棒料切割螺栓坯料之前，切割机器通知螺栓冲压装置，并且模具定位构件开始枢转并缩回到装置壳体中，从而减轻了棒料的端面和模具之间的压力。 当切割机从棒料切割螺栓坯料时，模具定位部件继续枢转进入壳体，并且允许螺栓坯料落下以便收集。 棒材再次进入，模具定位成在下一个螺栓坯料上重复压印过程。
