Description

Technical Field

[0001] The present invention relates to a waste wire recovery device, in particular to a waste wire recovery device for a slow-moving wire cutting machine. Background Art

[0002] The difference between slow-feed wire cutting machines and medium-feed and fast-feed wire cutting machines is that the wire used for processing is disposable. In the existing technology, an active traction device is generally set up outside the processing tank to pull the wire directly into the waste wire box. Because slow-feed wire cutting is a processing fluid immersion process, processing fluid will also leak out of the hole of the wire cutting outlet and need to be recovered and processed. In addition, since slow-feed wire cutting generally requires automatic wire threading, automatic wire threading requires the wire cutting head to be installed and sent into the wheel pair of the active traction device located outside the processing tank. The wire feeding distance is long and unstable. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a waste wire recovery device for a slow-moving wire cutting machine, which can effectively solve the shortcomings of the existing technology.

[0004] The present invention is achieved through the following technical solutions: a waste wire recovery device for a slow-moving wire cutting machine, comprising a processing tank, a processing fluid in the processing tank immersed in the processing fluid, a lower wire nozzle below the processed workpiece, a wire cutting traction wheel below the lower wire nozzle to pull the wire, and the wire is pulled downward, a wire guide tube is arranged obliquely to guide the waste wire out of the processing tank and into the waste wire box, the wire guide tube inlet is below the active traction wheel, and the outlet height is above the processing fluid level, and a wire cutting guide mechanism guides the wire into the wire guide tube inlet.

[0005] As a preferred technical solution, the wire cutting guide mechanism is an arc-shaped guide plate.

[0006] As a preferred technical solution, the wire cutting guide mechanism is a fluid nozzle.

[0007] As a preferred technical solution, the wire cutting guide mechanism is an annular belt.

[0008] As an optimal technical solution, there is a pair of short wire traction rollers at the outlet of the wire guide tube, and at least one short wire traction roller is installed on a passive roller moving device. The passive roller moving device drives it to move relative to the other short wire traction roller. When the wire is cut and the forward power transmitted by the active traction wheel is lost, the waste wire enters the waste wire box and is driven by the short wire traction active roller and the short wire traction passive roller.

[0009] The beneficial effects of the present invention are as follows: the present invention uses a wire cutting traction wheel arranged at the lower part of the lower wire nozzle to automatically thread the wire, and the wire only needs to pass through the lower wire nozzle and go straight for a short distance, which simplifies the automatic wire feeding process, and uses a wire guide tube with an inclined outlet higher than the liquid level of the processing tank to guide the waste wire out of the processing tank, while avoiding the problem of leakage of processing liquid through the wire outlet.
