Description

Technical Field

[0001] The utility model relates to the technical field of medium-speed wire cutting, in particular to a wire cutting fixture. Background Art

[0002] Medium-speed wire EDM reduces material deformation and errors caused by molybdenum wire loss through multiple cuts, resulting in relatively improved processing quality, which is somewhere between high-speed and low-speed wire EDM. The terms medium-speed, slow-speed, and fast-speed wire EDM all refer to wire EDM machines.

[0003] When using a medium-speed wire cutting machine, it needs to be used in conjunction with a fixture. First, the fixture needs to be fixed to the cutting position of the machine, and then the workpiece needs to be clamped and fixed by the fixture to facilitate wire cutting.

[0004] When using existing tooling fixtures, it is usually necessary to adjust the processing angle of the workpiece according to the processing requirements of the workpiece, and then clamp the workpiece through the fixture. However, the existing fixtures can usually only clamp and process a single workpiece at a time, and cannot limit and fix the processing angle of the workpiece. When multiple workpieces of the same batch need to be processed, the clamping and cutting angle needs to be adjusted again after each workpiece is loaded, which greatly reduces the wire cutting processing speed of the workpiece and increases the workload of the staff.
