Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a flexible wire cutting clamp. Background Art

[0002] Wire EDM, sometimes called wire cutting, is based on the principle of using a continuously moving thin metal wire (called electrode wire) as an electrode to perform pulsed spark discharge to remove metal and cut the workpiece into shape. Wire EDM technology is a special type of processing. It is different from traditional processing technology that requires mechanical force and mechanical energy to cut. It mainly uses electrical energy to process materials. Therefore, wire EDM technology is not limited by material properties and can process any hardness, strength, and brittle materials. It occupies a very important position in the current mechanical processing.

[0003] Existing wire cutting fixtures usually use magnetic fixings to adsorb the workpiece on the fixing rod. Although there is no direct mechanical force interaction between the electrode wire and the workpiece during the wire EDM process, which will not cause the workpiece to shift, the machine may cause the workpiece to shift due to vibration and other reasons, and it is difficult to fix it when processing rod-shaped workpieces, affecting the processing effect.
