Description

Technical Field

[0001] The utility model relates to the technical field of wire cutting machine tools, in particular to an adjustable upper wire rack for wire cutting machine tools. Background Art

[0002] The wire cutting machine uses a continuously moving thin metal wire (i.e., the wire cutting electrode wire) as an electrode to perform pulsed spark discharge on the workpiece, causing the metal to partially melt or even vaporize, thereby etching the metal and cutting it into shape. The electrode wire needs to maintain appropriate tension and a stable position during the cutting process. The upper wire stand can support the electrode wire to prevent the electrode wire from shaking significantly during high-speed wire cutting or work.

[0003] However, when it is in use, it does not have components to absorb tension fluctuations. When the tension of the electrode wire changes, such as unstable discharge energy during cutting or complex cutting paths resulting in uneven force on the electrode wire, the electrode wire will produce large vibrations. This vibration will make it difficult to maintain a stable discharge gap between the electrode wire and the workpiece, resulting in a decrease in machining accuracy. In addition, it lacks the function of adjusting the tension of the electrode wire, making it impossible to accurately control the tension at different machining stages, and its adaptability is low. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide an adjustable wire rack for a wire cutting machine. The spring and damper provided can produce elastic deformation when the tension of the electrode wire changes, absorb the fluctuation of the tension, ensure that the tension of the electrode wire is relatively stable during the processing, and keep the discharge gap between the electrode wire and the workpiece stable, thereby improving the processing accuracy. The screw rod 2 provided can lift the lifting plate to drive the spring and damper to lift, so as to adjust the tension of the electrode wire. In different stages of processing, such as the initial cutting, acceleration or deceleration stage during the cutting process, the tension requirements of the electrode wire are different. By controlling the tension of the electrode wire, the tension can be accurately adjusted according to the specific processing stage to meet the requirements of different processing stages.
