Product Description

Applications and features: Using the connecting flange pedestal for vertical machines, mandrels can be stored vertically.EWM consists of mandrel body, expandable mechanism, arc supporting plates, expandable linings, locking device of mandrel, device for connecting mandrel and winding machine. The diameter of mandrel can be changed freely by adjusting the spokes, which are driven by an electric driving mechanism or manual adjustment.EWM can be used in both horizontal and vertical winding machines, so the number of winding mandrels and their occupation of production space can be reduced greatly.Expandable Winding Mandrel (EWM) is a newly special mandrel for winding transformer coils in vertical or horizontal winding machines.    Specifications:   - - - - Parameter Model | Diameter Range | Batten Length | Batten Quantity | Total Length Excluding Spindle Head | Weight | Max Load | 1XB | f160~210 mm | 1000 mm | 8 | 1190 mm | 75 kg | 600 kg | 2XB | f200~260 mm | 1000 mm | 8 | 1160 mm | 90 kg | 600 kg | 3XB | f210~280 mm | 1500 mm | 8 | 1724 mm | 150 kg | 1000 kg | 4XB | f270~350 mm | 1500 mm | 8 | 1724 mm | 200 kg | 1500 kg | 0B | f340~470 mm (f450~580) | 2000 mm | 12 | 2290 mm | 950 kg | 3000 kg | 1B | f400~530 mm (f510~640) | 2000 mm | 12 | 2290 mm | 1020 kg | 3000 kg | 2B | f600~780 mm (f760~940) | 2700 mm | 12 | 3130 mm | 2500 kg | 8000 kg | 3B | f850~1050 mm (f1030~1230) | 2700 mm | 16 | 3130 mm | 3700 kg | 8000 kg | 4B | f1125~1325 mm (f1305~1505) | 3000 mm | 18 | 3430 mm | 5500 kg | 10000 kg | 5B | f1460~1660 mm (f1640~1840) | 3000 mm | 18 | 3430 mm | 7300 kg | 12000 kg | 6B | f1800~2060 mm (f2040~2300) | 3200 mm | 24 | 3630 mm | 9800 kg | 12000kg | 7B | f2420~2720 mm (f2700~3000) | 3000 mm | 30 | 3690 mm | 13000 kg | 15000 kg | - - - -
