ABSTRACT:
A work cutting apparatus in which clearance adjustment is simultaneously possible for the two sides of the L-shape of the blade by a single adjustment operation and in which the elevation system of the movable blade has a simple arrangement. The work cutting apparatus is provided with a fixed blade of which the plan shape is approximately L-shaped, and a movable blade that moves vertically and comprises an approximate l-shape in alignment with the fixed blade. The movable blade is mounted on the tip of a ram that pivots vertically via a pivot support shaft arranged on the lower frame. The pivot support shaft is an eccentric shaft and, by adjusting the rotation of the angle of the shaft, the oscillation center of the ram is changed and the clearance adjustment of the blades is possible. The axial direction of the pivot support shaft is angled with respect to both sides forming the L-shape of the fixed blade and by adjusting only the rotation angle of the pivot support shaft, clearance adjustment of both sides forming the L-shape of the blades may be simultaneously performed.
