Abstract:
A shear for cutting a rolled product such as a rod moving linearly along a path, said shear comprising:eccentrically bored sleeves;means for supporting said sleeves for rotation about fixed parallel first axes;carrier shafts supported in the bores of said sleeves for rotation about second axes parallel to said first axes;a pair of cutting blades;means for mounting said cutting blades on said carrier shafts for rotation therewith on opposite sides of said path;primary drive means for continuously rotating said carrier shafts; andadjustment means for rotatably oscillating said eccentric sleeves, said adjustment means comprising a crank shaft mounted for rotation about an axis parallel to the axes of rotation of said sleeves, link members connecting said crank shaft to said sleeves, and secondary drive means for intermittently rotating said crank shaft, said adjustment means being operable to alter the distance between said carrier shafts between a first setting at which said cutting blades rotate out of contact with said product, and a second setting at which said cutting blades coact during rotation to sever said product.
