Traverse Assembly : Traverse assembly with a suitable model of Rollring traverse unit is provided for layer winding. The pitch can be finely adjusted to suit the diameter of wire or width of the conductor. The linear movement of traverse is synchronized with the mandrel speed. Traverse shaft drive is through a two-speed gearbox for fine adjustment of the pitch. Reversal will be instantaneous and automatic. Winding length can be finely adjusted. Guide assembly can be positioned suitably along the length of former with handle on traverse shaft after disengaging the drive with an electromagnetic clutch.
Guide Carriage : Guide carriage with LM block and rail is mounted on a machined plate. Wire guide pulley assembly or a tensioning roller assembly is mounted on the carriage. Carriage will be moving and supporting the Wire or Rectangular conductor with its guides along the length of the machine. Separate guide assembly is provided for wire and rectangular conductor, which can be easily interchanged.
Tensioning Roller Assembly : Tensioning roller assembly is provided for guiding the rectangular conductor. Will be suitable to guide required number of conductors for layer winding. It consists of 6 horizontal rollers, suitably assembled. Top rollers are adjustable with handle for tightening the conductor.
Alternatively, Air cylinder with pressure regulator is provided.
Guide assembly for wire : Consists of 4 pulleys, 1 pulley with pneumatically brake and 1 pulley mounted on an adjustable arm to guide the wire to the mandrel.
Control Panel : Control panel with an AC Variable frequency drive, and accessories. Machine is operated with 2 foot switches, one for forward and another for reverse rotation of the mandrel.
Mandrel : We can supply mandrel to suit minimum and maximum dimension of coil to be manufactured.
Diameter of the mandrel is manually adjustable with handle and can be locked after adjustment. 8 wooden segments are mounted on the mandrel with multiple radial and axial supports. Wooden segments will be polished and will be made of hard wood.We can provide any mandrel diameter range according to your requirement.
Maximum Length of segments : 2000mm
Number of Segment : Eight
Expansion Range : Expansion in each stage varies from 40 mm to 100mm depending on size of mandrel pipe. Add on segments are supplied to increase the diameter range.
Maximum Coil weight : 2000Kg
Head Stock : Consists of heavy-duty gear box of robust design. Shaft mounted on heavy duty bearings and provided with a face plate for loading the mandrel.
Mandrel Shaft : We can supply shaft for loading the wooden former or adjustable former. Shaft or the Mandrel is bolted to face plate of head stock shaft and supported with tail stock pintle. Drive plate and threaded nut provided on the shaft for loading wooden former.
Tail Stock : Tail stock assembly is mounted on a swivelling arm or on a pedestal movable with handle. Tail stock pintle movement with handle with locking arrangement.
Unloading of finished Coil : Coil is removed easily with crane after opening tail stock.
Mandrel Shaft : Shaft mounted on the head stock drive plate and the tail stock pintle is supplied for loading the former
Mandrel with adjustable wooden segments.
Mandrel : Diameter of mandrel is manually adjustable with handle and locked after adjustment. 8 wooden segments are mounted on the mandrel with multiple radial and axial supports. Wooden segments will be polished and will bemade of hard wood.
