DIE DIMENSION ADJUSTMENT DEVICE AND TRIMMING DEVICE ARRANGED WITH THE DEVICE

摘要

PROBLEM TO BE SOLVED: To easily conduct trimming by a minimum size die to a plurality of objects to be worked having different outer diameters by adjusting the inner diameter or outer diameter of the die to a prescribed dimension. SOLUTION: A plurality of blocks are movably arranged on a base plate 11 in the radial direction, and a rotary plate 12 is rotatably arranged relative to the base plate. Oblong holes S1 are formed on the rotary plate and pins P1 are fitted to respective blocks, the rotary plate and respective blocks are arranged so as to fit the pins into the oblong holes. Further, by rotating the rotary plate relative to the base plate and thus moving respective blocks in the radial direction, the inner diameter or outer diameter of the die (consisting of a plurality of blocks) is adjusted to a prescribed dimension.
