Method and machine for the production of reinforcement and dowel side frames for concrete reinforcement from wire or rod or other material of prismatic cross section

摘要

According to the method, the transversal wire or rebar to be formed (1) and the longitudinal wires or rebars or other material of prismatic cross section (2), (3) are fed to the main forming and welding machine subsystem, in a stepwise manner, at the appropriate distance each time, through a driving mechanism (22-30). At this location, the transversal wire (1) is cut and then formed upon the action of a press (36). Welding of the formed transversal frame with one of the two longitudinal wires is performed while the formed transversal wire is still restrained by the action of the press (38) at the formation location. Welding with the second longitudinal wire is performed at the next production step, simultaneously with the welding of the next transversal frame with the first longitudinal wire, at the formation location. After the welding action, the transversal frame is released by the press and the forming tools (37-39), and the next production step is initiated. The product is made in a continuous shape and is cut at the proper lengths, by a cutter (45).
