High and Low Voltage Foil and Wire Winding Machines

Description

The design of Broomfield foil and strip transformer winding machines, which optimizes the configuration of the various assemblies, results in effective and efficient material handling and tension and keeps machine size to a minimum.

Our transformer winding machines offer an extra heavy-duty, welded and machined steel vertical frame. This guarantees the accurate alignment of all payoffs and guides with the winding axis.

Each of our Foil/Strip Transformer Winders are custom-configured with standard assemblies to match your application requirements.

Features

Operator Control Stations are located for accessibility and convenience during the machine operation. Switch labels are available in several languages.

Dual Roller Coil Pressing is supplied as standard on most of our foil winding equipment. The dual roller design with a pivoting head allows the rollers to change angle and spend more time on the corners. Interlocked with the E-Stop switch and up to 1,000 lbs. (453.59 kg) of pressure.

Foil Tension is provided by urethane covered steel rollers positioned after the guide assembly. Several styles provide a large range of tensions. May be powered to move the foil forward.

Heavy Duty Tailstocks of swing-away or slide-away designs to meet the need for winding mandrel support.

Inflatable Air Shafts with pneumatic disk brakes provide for de-spooling and tensioning insulation paper; may also have powered rewinds.

Foil Guide System, just prior to tensioning system, is simple, effective, and maintenance free to provide consistent edge alignment of your foil.

Inflatable Air Shafts for foil supply rolls are switch controlled and supported on the frame end by two heavy duty flange bearings piloted into each side of the frame. Many different diameters to accommodate most supply roll core sizes. Electric Rewinds are standard while powered unwind or loose loop control is optional.

Tailstock Supports on the longer payoff shafts, swing down for easy supply roll loading and unloading and lock up into place.

Specifications:

Broomfield Foil and Wire/Foil Winding Machines are custom configured according to your specific coil requirements.

We start with one of our standard winding machines (models) based on the speed, torque, and weight capacity requirements and add the features which tailor the winder to your needs.

Motor Equipment: 5 hp - 75 hp (3.73 kW - 55.93 kW) with AC variable frequency, AC vector, or DC regenerative motor drive controls.

Speed Reduction: Belt and pulley to a gear reducer for single speed machines or multi-speed gearbox when ease of speed range change is required.

Spindle Speeds: Single speed machines for high torque, low speed applications: 0 to 30 rpm. Other speed ranges available.

Multi-Speed Machines for Wire & Foil: 0-30 rpm in lowest speed range typically; 0-380 rpm in highest speed range, depending on base machine selected. Higher speed ranges available.

Faceplates: 14" (355.6 mm) and 22" (558.8 mm) diameter models are used depending on the torque requirements.

Spindle Center Height: 33" - 42" (838.2 mm - 1,066.8 mm) from the floor or your requirement.

Coil Diameters: Up to your requirement.

Material Capacities: Conductor foil/strips - 5" - 55" (127 mm - 1397 mm) wide, 0.020"-0.100" (0.51 mm - 2.54 mm) thick.

Insulation: 6" - 60" (152.4 mm - 1524 mm) wide.

Folded Edge ("Cuffed") Insulation Papers: 5" - 50" (127 mm - 1270 mm) wide.

Aluminum or Copper Magnet Wire: According to your requirements (round or shaped).

Material Payoffs: Conductor foil/strip - Various size inch or metric diameter air-expanded shafts with rotary unions for full time air supply, tensioned by air actuated disk brakes to control over-spin.

Insulation Paper: 3" (76.2 mm) diameter or metric diameter air expanded shafts with rotary unions for full time air supply, tensioned by air actuated disk brakes.

Folded (Cuffed) Edge Insulation Paper: Either fixed shafts with flanges for loose core rolls, or air inflated rotating shafts with brakes for solid core rolls.
