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。
