AI Technical Summary
The existing wire threading device of the slow wire EDM machine is not convenient for stably and quickly installing the electrode wire on the outer wall of the wire drum, which affects the processing efficiency.
A device was designed that includes a frame plate, a drive motor, a rotating rod, a wire drum, a wire threading mechanism, and a guiding mechanism. Through the cooperation of hexagonal bolts and guide blocks, the electrode wire is stably installed and guided. The pressure of the pressure rod and the guide roller ensures that the electrode wire is smoothly threaded into the wire drum.
It enables stable and quick installation of electrode wires, improves wire threading efficiency and processing accuracy, and ensures stable positioning and conveying of electrode wires on the wire spool.
