Abstract
The utility model relates to the field of reciprocating wire traveling linear cutting machines, and in particular relates to an electrode wire dynamic tensioning device. When in a high-speed reciprocating linear cutting machine, an electrode wire shows the extension characteristic of metal when in use and also appears loose and tight sides in a reciprocating operation, thus seriously impacting the surface quality of machining. The electrode wire tensioning device provided by the utility model comprises a wire cylinder part, an electrode wire and a wire bracket, wherein the electrode wire is led out from the wire cylinder part and supported by movable guide wheels (3, 12) and guide wheels (8, 9) respectively to form a certain tensioning degree. Before machining, a hand wheel is operated to enable a screw nut (15) to drive the wire cylinder part to integrally move on a guide rail 14, thus achieving the rough adjustment of the tensioning degree of the electrode wire. Corresponding data of the tensioning degree of the electrode wire is measured by a sensor; motors (6, 10) are respectively controlled to adjust the movable guide wheels (3, 12), so that the tensioning degrees on two sides of the electrode wire are accordant, namely dynamic fine adjustment is achieved.
