Description

The used VAI/Seuthe Direct Forming Tube Welding Line offers flexible cold forming capabilities, suitable for producing square and rectangular tubes. This line accommodates strip widths between 5.9" to 15.8" and thicknesses ranging from .059" to .236". The machine can process strips with tensile strengths up to 72,500 PSI, achieving speeds of up to 328 feet per minute. The system handles coil weights up to 20,000 pounds with coil inner diameters from 20" to 24" and outer diameters from 59.1" to 74.8". Tube lengths produced can vary from 157" to 472". Key features include an automatic tooling change for easy switching between square and rectangle profiles. With its flexible rafted mill design, it ensures high efficiency and precision. The welding process is managed by a 469 HP Thermatool Solid State Welder, ensuring reliable and consistent joins. Additional tooling for octagonal forming is also included, offering further versatility in production options. The line includes robust components such as entry sections with hydraulic expansion and disc drag brakes, a sophisticated strip joining and accumulation system with semi-automatic shear, and end-welder and double-cut shears for efficient operation. An advanced Siemens control system handles all electrical and automation functions, enhancing usability and maintenance. This comprehensive setup makes it well-suited for demanding production environments.
