Title:
ROTATION PLASTIC PROCESSING DEVICE AND ROTATION PLASTIC PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2016131976
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation plastic processing device and a rotation plastic processing method capable of appropriately thickening an outer circumferential part of a raw material to be processed as a thickening part which has a groove on an outer circumferential surface, while reducing a manufacturing cost.SOLUTION: A cylindrical spindle side outer mold 11 which is rotated and driven around a spindle rotation shaft center A by an outer mold rotation driving means is provided movably along the spindle rotation shaft center A on an outer circumferential part of a raw material support mold 2, a spindle side outer mold positioning mechanism F1 which fastens the cylindrical spindle side outer mold 11 to a prescribed spindle side outer mold operation position in a direction along the spindle rotation shaft center A is provided, a cylindrical tailstock side outer mold 12 is provided so as to be rotatable concentrically with the spindle rotation shaft center A and so as to be movable along the spindle rotation shaft center A and an outer mold pressing means which presses the tailstock side outer mold 12 to the spindle side outer mold 11 is provided on an outer circumferential part of tailstock mold 3.SELECTED DRAWING: Figure 4
