在近年来的拉伸应用中，从减少环境负担、改善劳动环境卫生和降低生产成本的角度来看，需要采取以下行动：减少所使用的拉丝润滑剂的量，用环境友好的润滑剂代替目前使用的润滑剂，降低了清洗粘附在产品上的润滑剂和处理用过的润滑剂的成本。本研究针对上述问题，探讨半干式和干式拉伸的实现方法。作为研究结果，我们研究了拉伸使用辊模和横向超声振动拉伸使用作者开发的平分模具。我们还研究了类金刚石（DLC）涂层对模具的影响。换句话说，除了使用被认为对实现半干式和干式拉伸有效的措施之外，还通过用DLC涂覆模具来研究使用免清洗润滑剂（即，在拉伸后不需要特殊去除过程的润滑剂）实现半干式拉伸和完全干式拉伸的可能性。研究结果表明，采用DLC涂层辊模拉伸和采用DLC涂层对分模横向超声振动拉伸是实现铝合金半干法和干法拉伸的有效方法。
In the application of drawing in recent years, from the viewpoints of the reduction of environmental burden, improvement of hygiene of labor environment and reduction of production costs, the following actions are necessary; the reduction of the amount of drawing lubricant used, the replacement of currently used lubricants with environmentally friendly lubricants, the reduction of costs for the washing of lubricant adhering to products and the disposal of used lubricant. In this research, we explored methods for the realization of semidry and dry drawing in order to resolve the above issues. As a result of the findings, we studied drawing using a roller die and transverse directional ultrasonic vibration drawing using a bisected die developed by the authors. We also investigated the effect of diamond-like carbon (DLC) coating on the dies. In other words, the possibilities of the realization of semidry drawing with the use of a wash-free lubricant (i.e. lubricant which needs no particular removal process after drawing) and of completely dry drawing were studied by coating the die with DLC in addition to the use of measures considered to be effective for realizing semidry and dry drawing. As a result of this study, it is concluded that the drawing method utilizing the DLC-coated roller die and the transverse ultrasonic-vibration drawing using a DLC-coated bisected die are effective in realizing semidry and dry drawing for aluminum materials.
