ABSTRACT:
A method and an installation for producing biconical wire, i.e., wire with repeating cylindrical and conical wire sections from a cylindrical starting material, in particular for producing helical compression springs inexpensively by using hot forming to form the conical wire sections. The installation has a heating unit (1) and a forming unit (2). The embodiment also includes a cooling unit (3) downstream from the heating unit (1), a cooling unit (4) downstream from the forming unit (2), a roll control (5), a re-rolling unit (6) downstream from the forming unit (2), another heating unit (7) for annealing or tempering, a cooling unit (8) downstream from the additional heating unit (7), an uncoiler (9), a roller straightening apparatus (10) and a coiler (11).
