Abstract

PURPOSE:To automatically adjust a lower dead center by rotating a screw shaft by rotating a worm gear and vertically moving a nut. CONSTITUTION:A connecting rod 4 is vertically interlocked at constant stroke with a crank shaft 2 is rotated when a driving part 1 is rotated. In this case, a spline shaft 6 is vertically moved at constant stroke in a worm gear 12. Now, when a worn shaft 11 is rotated by a driving part 10, the worm gear 12 is rotated to rotate the spline shaft 6. The nut 7 engaged with the screw shaft 5 of the above of the spline shaft 6 is then moved in the vertical direction together with a lower plate 24 to adjust the die height between an upper plate 21 and surface plate 25. The die height thus becomes easy to adjust and the noise of a crank press still.
