摘要： A method and system for forming a part from a workpiece including a hollow portion, using a mandrel and a conventional press such as a stamping press includes filling the hollow portion of the workpiece with a mandrel material and transforming the mandrel material to form a mandrel. The mandrel material is removable from the formed part and may be recycled to form a mandrel for another workpiece.
摘要翻译： 使用心轴和诸如冲压机的常规压力机从包括中空部分的工件形成零件的方法和系统包括用心轴材料填充工件的中空部分并转换心轴材料以形成心轴。 心轴材料可以从成形部件移除，并且可以被再循环以形成用于另一工件的心轴。

摘要： A tool adapted to form and method of forming a tapped hole within a workpiece in a single pass, includes a piercing section operable to punch a pilot hole in and produce a slug attached to the workpiece, and a tapping section operable to form a female thread along the periphery of the hole, and more preferably, an extruding section operable to push workpiece material away from the exterior surface defined thereby, an expanding section operable to expand the diameter of the hole, a sealing section operable to seal the hole during a hydroforming process, and a burnishing section operable to further expand and treat the periphery of the hole prior to tapping.
摘要翻译： 适用于在单程中在工件内形成螺纹孔的工具以及在工件内形成螺纹孔的方法的工具包括：刺穿部分，其可操作以在导向孔中冲压并产生附着在工件上的块塞，以及可操作以形成内螺纹 并且更优选地，可操作以将工件材料推离所限定的外表面的挤压部分，可扩展孔直径的扩展部分，可操作以在液压成形期间密封孔的密封部分 工艺和抛光部分，其可操作以在攻丝之前进一步扩展和处理孔的周边。
