Description

Technical Field

[0001] This utility model belongs to the technical field of cutting fixtures, and in particular relates to a fixture for wire cutting. Background Technology

[0002] Wire EDM is a machining method that uses a moving metal wire as an electrode wire. The pulsed electric spark discharge between the electrode wire and the workpiece generates high temperature to melt or vaporize the metal, forming a kerf, thereby cutting out the part. It has outstanding advantages such as small machining allowance, high machining accuracy, short production cycle and low manufacturing cost. When machining some workpieces with special shapes, special fixtures are required to fix the position of the workpiece.

[0003] Existing methods of fixing parts involve cutting a positioning plate according to the shape of the part, inserting the workpiece into it, and then cutting. This method is costly and inefficient. Another method involves directly fixing metal parts with bolts. This method has low compatibility with different metal parts, and changing bolts is too cumbersome, resulting in low work efficiency. Therefore, a wire EDM fixture is proposed.
