PURPOSE:To prevent the occurrence of a shift between the ends of steel strips upon abutting of ends of both steel strips, in a shearing machine for the end parts of steel strips which are subjected to abut-welding, by applying predetermined rake angles to upper and lower knives with respect the pass level of the steel strips. CONSTITUTION:A shear housing 101 is tiltably secured at its end by means of a pin 106, and a wedge 107 is engaged in a notch formed in the other end of the shear housing 101. The wedge 107 is moved to the right and left by a cylinder 108 to tilt the shear housing 101. With this arrangement, upper and lower knives 2, 4 may be inclined at predetermined rake angles. With this arrangement, the upper and lower knives 2, 4 which are inclined at the predetermined rake angles, may cut a steel strip with no planar shift and bend. |
