ROTATION PLASTIC FORMING DEVICE, WORKPIECE HOLDING UNIT, AND LOOSENESS DETECTION MECHANISM OF ROTATION PLASTIC FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To shorten time needed for changeover of a rotation plastic forming device and thereby improve the operation rate of the device.;SOLUTION: A rotation plastic forming device has a spindle mechanism 10, a workpiece holding unit A, and a spindle attachment/detachment mechanism B. The spindle attachment/detachment mechanism B is provided between the spindle mechanism 10 and the workpiece holding unit A and attaches and detaches the spindle mechanism 10 and the work holding unit A by rotation of the spindle mechanism 10.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2018,JPO&INPIT
