Problems solved by technology
[0002] During the processing of wire electric discharge machine tool, in order to ensure the precision and roughness of the surface of the processed parts, it is usually necessary to control the tension of the electrode wire. If the tension is too small, the electrode wire will easily move and affect the processing accuracy. Easy to break the wire, affecting the efficiency of processing
[0003] Especially when it comes to the automatic wire threading process, after the electrode wire is threaded into the nozzle, the electrode wire often does not have tension in the nozzle and moves, which affects the processing accuracy

The invention discloses an electrode wire tensioning device for a wire electric discharge machine tool, comprising an upper machine head (1), a lower machine head (2), a transmission mechanism and a wire retaining device arranged in the upper machine head (1) mechanism, the wire retaining mechanism is connected with the transmission mechanism in transmission, and when the electrode wire passes through the nozzle (3), the wire retaining mechanism makes the electrode wire (12) have tension. The electrode wire tensioning device of the electric discharge wire cutting machine provided by the invention can improve the precision and roughness of processing, and the electrode wire with tension will not touch the nozzle, which has a protective effect on the nozzle.
Description
technical field [0001] The invention belongs to the technical field of electric discharge wire cutting machine tools, in particular to an electrode wire tensioning device for electric discharge wire cutting machine tools. Background technique [0002] During the processing of wire electric discharge machine tool, in order to ensure the precision and roughness of the surface of the processed parts, it is usually necessary to control the tension of the electrode wire. If the tension is too small, the electrode wire will easily move and affect the processing accuracy. It is easy to break the wire and affect the efficiency of processing. [0003] Especially when it comes to the automatic wire threading process, after the electrode wire is threaded into the nozzle, the electrode wire often does not have tension in the nozzle and moves, which affects the processing accuracy. Contents of the invention [0004] The object of the present invention is to provide a wire electrode te...
