These new high precision CNC controlled Coil Spreader Machines are part of a range of electromechanical automation equipment now offered by Rotary Engineering UK Ltd.
These machines are used to make a full formed coil from a loop and can be used in conjunction with our range of CNC Winding Machines.
The coil is held in place at both ends by the pin cylinders mounted in the knuckle holders. The manipulators at the end of the spreader arms hold the straight section of the coil firmly in place.
During the forming of the coil, the spreading arms move simultaneously outwards in a rotary motion. At the same time AC servo motors in the spreader arms drive the manipulators downwards towards the rotation axis of the spreader arms. The knuckle holders containing the pin cylinders also move inwards along the coil axis to the desired length, allowing the correct length between the coil knuckles to be formed.
On completion of the coil spreading operation, the cylinders and servo motors are reversed by a small amount to eliminate coil spring back.
Once completed, the cylinders are withdrawn, the manipulators are released, and the coil can be removed.
The combination of both numeric control and mechanical linkage technology is used to ensure the machine automatically and continuously performs the coil spreading process from unformed loop to finished product.
This high forming precision means there is no need to use any other reshaping after spreading. By using this automated equipment any possibility of damage to insulation by using a soft hammer on the coil during the reshaping process is eliminated.
