Surface cleaning device for copper wire machining

The surface cleaning device for copper wire machining comprises a collecting frame, a discharging pipe, fixed vertical plates, a fixed supporting plate and a fixed disc, the fixed vertical plates are symmetrically arranged, sliding clamping grooves are evenly formed in the upper ends of the fixed vertical plates, and lifting plates are slidably clamped in the sliding clamping grooves; first fixing plates are evenly and fixedly installed between the lifting plates, an electric hydraulic cylinder is fixedly connected to the upper end of the lifting plate located in the middle, and first connecting plates are evenly and fixedly installed at the bottom ends of the lifting plates. In the using process, the steel wire passing through the device can be subjected to three-section type cleaning treatment through the upper extrusion clamping cover and the lower extrusion clamping cover, so that the outer surface of the steel wire passing through the device can be smooth, neat and free of dust and foreign matter, and th
