    摘要: A copper alloy wire and a manufacturing method thereof are provided. The copper alloy wire includes: by weight percentage of components, 0.3 to 0.45 of argent, 0.01 to 0.02 of titanium, and a remaining part that is formed by copper and unavoidable impurities. The method for manufacturing the copper alloy wire is performing two-phase vacuum melting: first performing vacuum electric arc melting into a copper-titanium mother alloy, and then performing vacuum induction melting with remaining components into a copper alloy wire material by means of continuous casting; then drawing the copper alloy wire material into a copper alloy fine wire by a non-slip wire drawing device in a material even-flow wire drawing manner, and finally performing thermal treatment on the copper alloy fine wire by using argon as a protection gas, so as to complete a process of the copper alloy wire.

    摘要: Bending machine for one or more metal products such as, for example, bars (11a, 11b), reinforcement round pieces, structural shapes, tubes or other profiles, comprising at least a bending unit, a main drawing unit, able to draw the bar along an axis of advance toward the bending unit, and a main shearing unit disposed between the bending unit and the main drawing unit. The machine also comprises a secondary drawing or extraction unit disposed between the main drawing unit and the main shearing unit. The secondary drawing or extraction unit is configured and programmed to draw an end portion of bar, exiting from the main drawing unit, along the axis of advance toward the bending unit.
