摘要： An apparatus capable of quickly and accurately switching the slide stroke in two stages without changing the die height. One form of the apparatus includes an eccentric portion of a crankshaft and an eccentric sheave which are disposed in such a manner as to be eccentric in the same direction. Holes having axes intersecting the crankshaft axis are formed in the eccentric portion, the eccentric sheave and a con'rod, and are combined in such a manner that those holes of the eccentric portion and the eccentric sheave are coaxial with each other and those holes of the con'rod and the eccentric sheave are coaxial with each other. First lock pins are movably received in the hole of the eccentric portion, while second lock pins are movably received in the hole of the con'rod. The first and second lock pins are selectively engaged with the corresponding holes to adjust the stroke of the con'rod. In another form, the stroke of a con'rod is adjusted by a structure including a divided eccentric sheave fitted on a crank-pin portion provided between a pair of arm portions integral with a crankshaft, and a ring member fitted on the eccentric sheave.
