Fully automated production line, using steel coils of 6, 8, 10, 12; or straight bars 14 and 16 diameter (up to 24 on request) to automatically cut and bend electrically welded steel structures for columns / beams and foundation beams, as well as reinforcement straight bars. Longitudinal bars can be made with steel diameters up to 16 mm, while transversal bars can be of 6 up to 10 mm / 12 on request.

With extensive use of silent, clean, and very fast brushless motors with encoders, it straightens steel coils up to 12 mm diameter, measures and cuts to specification the bars, ensuring high productivity, total flexibility to mix and no scrap of raw materials, realizing the ‘one piece flow’ needed to deliver just in time to construction site. Feeding with straight bars up to 16 mm is also available, without affecting the flexibility of the production line.

The production line consists of longitudinal and transversal wire reel tables with straightening and cutting units, reinforcement wire conveyor, welding units, mesh puller and output conveyor, mesh bending unit with label printer and automation system. The label printer at the end of the line receives data to print from the plant supervisor and control system, thus labelling every single component produced.The control system of the machine receives all data on line from the central plant planning computer to which it is fully integrated. The line control is based on a PLC system to control servo motion drive, inverter, analogical and digital I/O.

Advantages

  • High flexibility - no set up costs, economic batch size is 1 single piece thanks to the full automation
  • Easy to use, high productivity machine
  • Zero material scrap - thanks to steel coil feeding all bars are cut to measure
  • Integrated with the plant management system
