| titleOfInvention | Manufacturing method of back pulley made of sheet metal |
| abstract | The sheet metal cup-like material 4 which has the circular board | substrate part 2 and the cylinder part 3 which protruded in the axial direction of the said board | substrate part 2 from the outer peripheral part of this board | substrate part 2, By preparing and forming the upper end of the cylinder part 3 by the annular groove part 13, the cylinder part 3 has the annular shape which protruded in the direction opposite to the direction which the cylinder part 3 extended and protruded. The protruding portion 15 is formed, and the annular protruding portion 15 and the cylindrical portion 3 are looped by the rotary lower frame 5e, the rotary upper frame 6d and the rolling roller 18 for flattened surface formation. The grooves 13 in the shape are held at a pressure until they disappear at least, so that the outer circumferential surface 15a of the protruding portion 15 and the outer circumferential surface 30 of the tubular portion 3 are formed to face each other. Thereby, the length h4 of the axial direction of the sheet metal back pulley 11 was made to increase, and it was made possible to utilize the whole length of the lengthened axial length h4 as an effective length. |
