Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire EDM technology, specifically relating to a CNC wire EDM clamping frame. Background Technology
[0002] CNC wire cutting, also known as CNC electrical discharge machining (Wire Cut EDM), is a precision machining technology that uses an electrode wire (such as molybdenum wire or tungsten-molybdenum wire) as the tool electrode. Under the action of a pulsed power supply, the workpiece is cut through a spark discharge generated between the electrode wire and the workpiece. The following is a detailed introduction to CNC wire cutting: The CNC wire cutting machine tool is controlled by a CNC program to move the electrode wire along a predetermined trajectory, while simultaneously generating a pulsed spark discharge between the electrode wire and the workpiece. The spark channel instantly generates a large amount of heat, melting or even vaporizing the workpiece surface, thereby achieving the cutting purpose.
[0003] Existing wire EDM equipment does indeed have certain limitations in clamping parts of different sizes and thicknesses. This shortcoming can be described in detail from the following aspects: Many existing wire EDM equipment are designed with clamping devices optimized for parts of a specific size or thickness range. This means that when the size or thickness of the part exceeds this range, the clamping device may not be able to clamp it effectively, or the clamping effect may be unsatisfactory, thus affecting the cutting accuracy and stability. The fixture is a key component in wire EDM equipment used to clamp parts. However, existing fixtures often lack sufficient adaptability and cannot be flexibly adjusted according to different sizes and thicknesses of parts. This leads to the need for frequent fixture changes or complex adjustments when processing parts of different specifications, which not only reduces production efficiency but also increases operational difficulty and cost. Due to the large differences in the size and thickness of parts, existing clamping devices have difficulty ensuring the uniformity of clamping force when clamping different parts. Uneven clamping force may cause the part to shift or deform during processing, thus affecting the cutting accuracy and surface quality. Especially when processing high-precision parts, such shifting or deformation may directly lead to the scrapping of the part. Utility Model Content
