Abstract

PURPOSE: To reduce the time required to separate the work from the cutting equipment after completion of cutting operation and to operate cutting with high speed and high precision by use of curved blades which make rolling motion.
CONSTITUTION: Lower blade support 2 fitted with a guide groove which guides the up-down movement of upper blade support 1 is supported at the lower part of shear frame 4 by means of parallel links 3. On the other hand, crankshaft 7 which extends above upper blade support 1 in the direction of its width is fastened to the above-described frame 4. Eccentric parts 8, 9 having different phases, which are provided on crankshaft 7, are connected to upper blade support 1 having curved blade 17 by means of two connecting rods 12, 13, which are fitted with spherical bearings on both ends. In the shear of this construction, lower blade support 2 is made to move forward and backward in synchronizing with the feeding speed of the work, and upper blade 17 of upper blade support 1 is made to roll and descent with respect to the straight blade (lower blade) of lower blade support 2, and thus the work is cut while it is in traveling motion.
