Traverse Assembly : Ball screw operated by Servo motor provided for Layer Winding. Traverse movement is very accurately controlled with reference to program stored in the HMI . Layer winding as per the design specifications is controlled by the PLC and servo drive.
Guide Carriage : Guide Carriage with LM block and Rail mounted on a machined plate provided . Wire guide pulley assembly or tensioning roller assembly are mounted on the carriage. Carriage will be moving and supporting the Wire or Rectangular conductor with its guides along the length of 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 conductor to be layer wound. Consists of six number horizontal rollers suitably assembled. Top rollers are adjustable with handle for tightening the conductor .alternatively Air cylinder with pressure regulator can be provided ( optional ).
Guide assembly for wire : Consists of four number pulleys, one number pulley pneumatically braked, and one pulley mounted on adjustable arm to guide the wire near to mandrel.
Control Panel : Control panel with Siemens make AC variable frequency drive, Servo drive, PLC,HMI, Encoder, and accessories are supplied. Operating desk with HMI is suitably mounted on a swiveling arm ,easily accessible to operator. HMI : Program can be created and stored in the HMI. HMI will display all winding parameters and status of the winding.
Several Winding program like - Left or right side start, starting point, Number turns per layer, total number of turns , Diameter of wire, width of conductor, Pitch, Coil length, Number of turns for Tapping, Slow down number of turn can programed and stored in the HMI. Program can be recalled as required by the operator.
1)Mandrel : We can supply mandrel to suit minimum and maximum dimension of coil to be manufactured.
Diameter of mandrel is manually adjustable with handle and can be locked after adjustment. Eight number of wooden segments are mounted on the mandrel with multiple radial and axial support. Wooden segments will be polished and will be made of hard wood. Mandrel diameter range as required can be offered. 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.
