The invention discloses a
wire cutting machine capable of automatically switching
electrode wires, which is provided with a wire passing channel for the
electrode wires to automatically pass through, and comprises a first wire storage mechanism, a second wire storage mechanism and a third wire storage mechanism, the second wire storage mechanism is used for winding a second
electrode wire; the clamping and conveying mechanism can clamp the electrode wires forwards or backwards, and the electrode wires comprise the first electrode wire and the second electrode wire; the switching mechanism can drive the first electrode wire or the second electrode wire to penetrate into the wire penetrating channel in a
butt joint mode so that automatic wire penetrating and
cutting can be achieved. The switching mechanism is used for achieving switching between the
molybdenum wire and the
copper wire, the
molybdenum wire is used for primary roughing, the
copper wire is used for secondary trimming, automatic wire penetrating and automatic
cutting are combined, the two procedures are integrated on one device, automatic switching is achieved, the technological process is greatly simplified, the standby time is shortened, meanwhile, the characteristics and cost of the
copper wire and the
molybdenum wire are considered, and the production efficiency is improved. And the
machining cost is reduced, the
automation degree of equipment is greatly improved, and the
machining efficiency is remarkably improved.
