Abstract
An apparatus and method to feed and shear metal bars, comprising a shearing unit that shears the metal bars sequentially into segments of desired length, and an alignment and translation unit, which feeds the metal bars to the shearing unit, provided with butting member suitable to cooperate with the tail ends of the metal bars in order to align them longitudinally with respect to each other. The butting member comprises a magnetic portion facing toward the tail ends of the metal bars, and conformed so as to generate a magnetic or electromagnetic attraction force on the tail ends, so as to attract the metal bars to itself and to keep the relative tail ends substantially aligned and in contact with the butting member.
Claims12
An apparatus to feed and shear metal bars, comprising at least a shearing unit able to shear said metal bars sequentially into segments of desired length, and an alignment and translation unit, able to feed said metal bars to said shearing unit, provided with a butting member suitable to cooperate with the tail ends of said metal bars in order to align them longitudinally with respect to each other, wherein said butting member comprises at least a magnetic portion facing toward the tail ends of said metal bars, and conformed so as to generate a magnetic or electromagnetic attraction force on said tail ends, so as to attract said metal bars to itself and to keep the relative tail ends substantially aligned and in contact with said butting member.
A method to feed and shear metal bars, comprising at least a first step in which a plurality of said metal bars are aligned longitudinally by means of an alignment and translation unit;
- a second step in which said aligned metal bars are fed to at least a shearing unit;
- and a third step in which said metal bars are sheared sequentially into segments of a desired length by means of said shearing unit, wherein in said first step at least a first substep is provided in which said metal bars are aligned longitudinally with respect to each other by the action of a butting member acting on the respective tail ends and provided with at least a magnetic portion facing toward the tail ends of said metal bars, and conformed so as to generate a magnetic or electromagnetic attraction force on said tail ends, so as to attract said metal bars to itself and to keep the relative tail ends substantially aligned and in contact with said butting member.
