    • PROBLEM TO BE SOLVED: To simplify diameter contraction work of inside diameter and outside diameter when manufacturing a rubber hose whose inside diameter and outside diameter on one end side are formed as contracting diameters, and improve its quality. SOLUTION: When mounting a contracted outside diameter jig 150 for contracting outside diameter on one end side of the hose, a worker pushes the contracted outside diameter jig 150 into a side of rubber hose raw material PGH by using a guide shaft part 118 as guide. Consequently, the rubber hose raw material PGH enters a contracted diameter forming fitting hole 152 of the contracted outside diameter jig 150 from its end part side, its outside diameter is contracted in the contracted diameter forming fitting hole 152, and its inside diameter is contracted in a contracted diameter forming shaft part 114. The contracted outside diameter jig 150 is fitted and mounted in a condition in which centering is performed for the rubber hose raw material PGH by the guide shaft part 118 being coaxial with the contracted diameter forming shaft part 114.

    • 要解决的问题:为了简化制造其一端侧的内径和外径形成为收缩直径的橡胶软管的内径和外径的直径收缩工作,并提高其质量。 解决方案:当安装用于在软管的一端侧收缩外径的收缩的外径夹具150时,工人通过使用导向轴部118将收缩的外径夹具150推入橡胶管原料PGH的一侧 作为指导。 因此,橡胶软管原料PGH从其端部侧进入收缩外径夹具150的收缩直径形成装配孔152,其外径收缩在收缩直径形成装配孔152中,并且其内径收缩 收缩直径形成轴部分114.收缩的外径夹具150在通过与收缩直径形成轴部分114同轴的引导轴部分118对橡胶管原料PGH进行定心的状态下进行安装和安装。 版权所有(C)2007,JPO&INPIT
