Transformer Radiator Fully Automatic Production Line/Making Machine

1.Production process
Feeding - Automatic unwinding - rolling - Hydroforming - multi-spot welding -side seam welding - terminal seam welding - side hobbing - terminal cutting - unit piece finished.

2.Transformer radiator performance and requirements
(1)Product Specifications: panel width 320, 480, 520mm (as per customer's requirements). The jointed panel mouth thickness: 42mm, to meet two panels to be one seam welding.
(2)Center distance: 500mm-4000mm.
(3)The center distance tolerance: ± 1.0mm.
(4)Single-panel pressure: positive pressure≥0.15Mpa, negative pressure≥133Kpa, no deformation.
(5)Panel shape: crew cut at the ends, forming part with five degree angle.
(6)Oil groove depth of single piece: depth ≥ 11mm (plate thickness 1.0mm)
depth ≥ 11.5mm (plate thickness 1.2mm)
(7)Oil Groove Quantity: panel width 320mm 3sets
panel width 480mm 5sets
panel wide 520mm 6sets

(8)Workpiece material: high quality cold-rolled coilsl: ST12, SPCC, DCO1, thickness: 1.0mm-1.2mm
(9)The width of the materials: panel width 320 coil width 335
panel width 480 coil width 495
panel width 520 coil width 535

3.Related parameters of the production line
The production line processing requirements goals:
(1)The specific production efficiency: as for 2000 mm length of the workpiece, it will reach over 35pcs/hour
(2)Side seam welding machine's speed of not less than 1.7 m/ min
(3)Roll rolling line speed 6.4m/min.
(4)The bottle neck of the production line is the multi-spot welding, if add an extra, production will improve 60%.
(5)The total power is about 315KVA.
(6)The production line needs the 2-3 operators, depending on situation.
(7)The general working piece height is 1000 mm.
(8)Equipment design and manufacture should be consistent with ISO international standards, environmental standards and safety standards.
(9)All parts of the equipment and a variety of instruments units of measurement should be all with standard of International System of Units (SI).
