METHOD OF SEPARATING METALLIC PARTS FROM MATERIALS WITH ANISOTROPIC PROPERTIES BY ELECTRODE-WIRE AND DEVICE FOR ITS USE Russian patent published in 2017 - IPC B23H7/02 B26D1/547 

FIELD: electricity.

SUBSTANCE: tension of the electrode-wire and the supply of current pulses to it are carried out. When rewinding and tensioning the electrode-wire, the separable metal part is fed to the electrode-wire and the current pulses are applied to it. While reducing the frequency of current pulses, the rewinding of the electrode-wire is stopped, and the feed of the part towards the electrode-wire is carried out until the occurrence of a short circuit current, wherein the pulse current supply is disabled, the tension of the electrode-wire is reduced from the rewinding node to obtain its length from the phase involved in the part separation, not less than the greatest thickness of the separable metal part. After the tension of the electrode-wire is increased to the original value. The rewinding is performed with increasing its speed until the initial frequency rate of the current pulses is reached, and the separation continues until the next reduction in the frequency rate of the current pulses. The device contains a generator, mechanisms of rewinding and tensioning the electrode-wire, adapted to adjust the magnitude of the force rewinding, a tension roller of the electrode-wire, installed after the mechanism of tensioning the electrode-wire, a differential sensor of the frequency rate of the current pulses, a controller of the electrode-wire moving with an end switch and a control device of tensioning and rewinding the electrode-wire. The differential sensor of the frequency rate of the current pulses is connected through the end switch of the controller of the electrode-wire moving with the control device of tensioning and rewinding and with the device of tensioning and rewinding the electrode-wire.

EFFECT: increased productivity, process stability.
