Transformer Radiator Fin Plate Forming and Welding Line

Our transformer radiator fin plate forming and welding line take advantage of the technology from Germany GEORG and Canadian MTM. It is designed mainly to manufacture fin plate of different widths (520 or 535mm, 480mm, 320 or 310mm) with high efficiency. This forming and welding line is made of automatic decoiler, roll forming machine, two-piece joining device, multi-head spot welding machine, double-side seam welding machine, terminal welding machine, double-side edge trimming machine, terminal cutting machine, as well as other related devices like transmitting belt and PLC control system.

Size changing on the roll forming machine is driven by hydraulic system, whereas other machines and transmitting belts are manually adjusted. The central distance should exceed 1200mm if this equipment operates in a fully automatic manner. Thus, the workpiece needs to be manually fed into each welding machine if the distance is less than 1200mm.

• Width of fin plate320mm or 310mm, 480mm 520mm or 535mm
• Central distance500-4000mm (When the distance is less than 1200mm, the automatic production method is not enabled.)
• Central distance error± 1.0mm
• Single piece bearing pressurepositive pressure ≥ 0.15MPa; negative pressure≥133Kpa. (No deformation)
• Oil clearanceIf material thickness is 1.0mm, the oil clearance should exceed 11mm
  If the thickness is 1.2mm, the oil clearance should be more than 11.5 mm
• Quantity of oil channels3 oil channels are available for producing fin plate of 310 or 320mm width;
  5 oil channels are provided to manufacture 480mm width fin plate;
  6 oil channels are supplied if the width is 520 or 535mm
• Suitable raw materialST12, SPCC, DC01 cold rolled steel
