項記載の曲がりホース製造装置。[Claims for Utility Model Registration] (1) A die having an opening that defines the outer peripheral shape of the hose and a material passage that is continuous with the opening; A hose manufacturing device comprising: a head portion having a mandrel defining a circumferential shape; and a supply portion supplying molding material to the material passage of the head portion, wherein the mandrel has an outer circumferential surface of the mandrel and an outer circumferential surface thereof. has an eccentric portion that changes the relative distance between the material passage and the inner circumferential surface of the material passage, and the eccentric portion partially varies the passage resistance of the molding material in the inner circumferential direction of the material passage. A curved hose manufacturing device characterized in that the discharge speed of the molding material discharged from the opening is partially varied in the circumferential direction to form a curved portion. (2) The eccentric part has a tapered shape whose cross-sectional area gradually increases in the axial direction, and is movable relative to the mandrel in the axial direction, and the head part has a moving device for moving the eccentric part. A curved hose manufacturing apparatus according to claim 1 of the patent registration claim. (3) A plurality of eccentric parts are provided around the mandrel, and each of the eccentric parts moves relative to each other in the axial direction of the mandrel.
Bent hose manufacturing device as described in section.
