Work cutting apparatus

摘要

A work cutting apparatus (2) where clearance adjustment is simultaneously possible for the two sides of the L-shape of the blade (12) by a single adjustment operation and where the elevation system of the movable blade has a simple arrangement. A work cutting apparatus provided with a fixed blade (13) of which the plan shape is approximately L-shaped, and a movable blade (12) 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 (15) that rotates vertically via a rotating support shaft (14) arranged on the lower frame. The rotating support shaft (14) is an eccentric shaft and by adjusting the rotation angle, the oscillation center of the ram is changed and the clearance adjustment of the blades is possible. The axial direction of the rotating 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 rotating support shaft, clearance adjustment of both sides forming the L-shape of the blades may be simultaneously performed.
