Claims

[Claims for Utility Model Registration] (1) Concave or H cross section with a cylindrical part on the outer periphery
The circular material of the mold is rotated around its shaft material, and the outer peripheral surface of the cylindrical portion is pressed and ironed through the switching of multiple processing rollers, and the inner periphery of the cylindrical portion is ironed using a mold attached to a rotatable main shaft mechanism. In a spinning device for forming a surface, a plurality of roller heads are provided independently in the rotation direction of the main shaft in the main shaft mechanism, a processing roller is attached to the roller head, and further,
Processing rollers are mounted on at least one of the roller heads at intervals in the axial direction of the main shaft,
A pressing cylinder mechanism is provided that allows each of the processing rollers to move forward and backward toward the mold, and further,
A spinning device comprising a cylinder mechanism that allows each of the roller heads to reciprocate in the axial direction of the main shaft. (2) The spinning device according to claim 1, wherein a plurality of processing rollers of different types are mounted on each roller head at intervals in the axial direction of the main shaft.
