摘要： PROBLEM TO BE SOLVED: To provide a hollow coil spring which can prevent inner surface corrosion and improving product appearance, and to provide a method for manufacturing the same.SOLUTION: In an end sealing step, the material of an end Wa of a spring material W is gathered by machining to seal the end Wa. Spinning is preferably carried out as the form of machining. While pressing the end of the spring material W with a squeezing roller R, for example, toward the inside in the radial direction, the squeezing roller R is appropriately moved in the axial direction as necessary. The end Wa of the spring material W is thus blocked, as shown in Fig.3, eliminating the need to use a separate member such as a lid member. Such an end sealing step can be carried out immediately after an inner surface processing step, for example. In a coil forming step performed after the end sealing step, even when the end Wa of the spring material W is gripped and the spring material W is wound around a rod, the formation of a gap at the end Wa can be prevented.
摘要翻译：要解决的问题：提供一种能够防止内表面腐蚀并改善产品外观的中空螺旋弹簧，并提供其制造方法。解决方案：在端部密封步骤中，弹簧材料W的端部Wa的材料通过机械加工来密封端部Wa。旋转优选作为加工的形式进行。当用挤压辊R将弹簧材料W的端部例如朝向径向内侧挤压时，挤压辊R根据需要在轴向适当地移动。因此弹簧材料W的端部Wa被阻挡，如图3所示，消除了使用诸如盖构件的单独构件的需要。例如，可以在内表面处理工序之后立即进行这样的端部密封工序。在端部密封工序后进行的线圈成形工序中，即使弹簧材料W的端部Wa被夹持并且弹簧材料W卷绕在杆上，也可以防止在端部Wa形成间隙。版权所有（C）2012，JPO＆INPIT
