Document Type and Number:
Japanese Patent JP6853702
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve a reduction in processing cost and prevent a change in strip strength and dimensional change by dispensing with two plastic deformations of a strip for screw manufacture, and to effectively utilize a space of a processing plant by efficiently arranging a screw apparatus.SOLUTION: A screw manufacturing apparatus 100 constituted by joining a long strip 118 with an auger shaft 114 at a predetermined angle comprises a shaft feed part 130 that feeds the auger shaft 114, a shaft rotating part 140 that rotates the shaft, a strip feed part 200 that feeds the strip 118 to come in contact with the peripheral face of the shaft, and a joint part 150 that joins the strip 118 with the auger shaft 114, where the strip feed part 200 transfers a linear strip 118 at a standby angle inclined closer to the side of the auger shaft 114 than at a predetermined angle while deflecting the same until reaching a predetermined angle, thereby feeding the same at a predetermined angle to the auger shaft 114.SELECTED DRAWING: Figure 1
