Patent ID: 8276266

Claim:
A semi-automatic system for the manufacture of large electrical induction coils, comprising: a control unit configured to receive measurements related to an electrical induction coil to be formed; a pressure head operably connected to the control unit and mounted on a support on which the pressure head pivots between a resting position and a working position, wherein a size of the coil to be formed is known by the control unit during manufacture based upon a comparison by the control unit of a real position of at least a portion of the pressure head against a theoretical position of the at least a portion of the pressure head as determined by the control unit from the measurements, the pressure head having a vertical axle and a horizontal axle; at least one vertical wheel mounted on the vertical axle and positioned to accept a conductor material and regulate height and flatness in a coil formed in the conductor material, wherein the at least one vertical wheel comprises at least one auxiliary horizontal disc positioned such that when the conductor material is fed into the pressure head the conductor material maintains contact with the at least one vertical wheel; at least one horizontal wheel mounted on the horizontal axle positioned to accept the conductor material and position the conductor material on top of a previously formed coil; at least one hydraulic cylinder attached to the vertical and horizontal axles, the hydraulic cylinder operably connected to the control unit and configured to adjust coiling pressure exerted on the conductor material by adjusting hydraulic pressure on the axles; and a conductor feeder mounted on the support, the feeder comprising a set of clamps such that the conductor to be coiled is positioned tangent to the vertical and horizontal wheels, thus eliminating traction tensions in the conductor as well as a risk of stretching the conductor during coiling.
