Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, and in particular to a protective mechanism and a wire cutting machine thereof. Background Technology

[0002] A wire EDM machine is a processing device that uses a fine metal wire as an electrode to remove metal and cut it into shape through spark discharge. Its basic working principle is to use a continuously moving fine metal wire to generate high temperature through spark discharge, so that the local metal melts, oxidizes and is corroded away, thereby realizing the cutting and shaping of the workpiece.

[0003] Wire EDM machine protective mechanisms prevent flying shavings from injuring operators during the cutting process. However, traditional wire EDM machine protective mechanisms are too large, making them inconvenient for workers to install and disassemble. In addition, the top of traditional wire EDM machine protective mechanisms is an open structure, allowing small amounts of shavings to easily fly out from above the protective mechanism and fall into the corners of the worktable, requiring the operator to clean them up after cutting, which is time-consuming and laborious.
