Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of extrusion method for producing of magnesium alloy solder wire is provided, can prepare the magnesium alloy solder wire of 1~4mm different-diameter, satisfy industrial demand.
For realizing this purpose, the main production equipments that the extrusion method for producing of magnesium alloy solder wire of the present invention relates to has horizontal extruder, magnesium alloy solder wire extrusion die, magnesium alloy ingot blank firing equipment, mold heated equipment, wire-drawing die; Wherein said magnesium alloy solder wire extrusion die is the extrusion die with porous work zone.
Concrete production method of the present invention is:
1, adopts the magnesium alloy pipe Extrusion Porthole Die for Aluminium Profiles, the work zone between the upper and lower mould is designed to have the porous work zone that aperture size is 1~4mm, constitute the magnesium alloy solder wire extrusion die; Design simultaneously one with the corresponding wire-drawing die in shape aperture, porous work zone.
2, industrial semicontinuous magnesium alloy ingot blank is put into the ingot blank firing equipment, be heated to 250~440 ℃; Magnesium alloy solder wire extrusion die and dummy block are put into mold heated equipment, be heated to 230~420 ℃; The recipient temperature of horizontal extruder is heated to 300~450 ℃.
3, after recipient and magnesium alloy solder wire extrusion die with porous work zone are heated to design temperature, it is fixing that extrusion die is put into die support, magnesium alloy ingot blank after the heating is put into the recipient of extruder, put into the dummy block that has heated then, start extruder, extrusion axis enters recipient, promoting dummy block pushes magnesium alloy ingot blank, extrusion speed is controlled at below the 10m/min, and the magnesium alloy solder wire tube-surface blackout to prevent to squeeze out influences surface quality and mechanical property.Obtain magnesium alloy solder wire tubing after the extruding.
4, with the magnesium alloy solder wire tubing that squeezes out after burr is removed in the wire-drawing die cold-drawn, obtain magnesium alloy solder wire, can carry out reel, packing.
The welding wire that the present invention prepares 1~4mm diameter be by in the control magnesium alloy solder wire extrusion die between the upper and lower mould aperture of porous work zone realize, the aperture of work zone can be processed into 1~4mm as required, the magnesium alloy solder wire that squeezes out is a welding wire pipe, the external diameter of welding wire pipe can design adjustment according to the tonnage of extruder, magnesium alloy solder wire distributes along the external diameter of welding wire pipe, and its radical is controlled by the diameter of welding wire and the external diameter girth of welding wire pipe.
The invention has the beneficial effects as follows provides a kind of effective magnesium alloy solder wire extrusion method for producing.This method can be produced many magnesium alloy solder wires simultaneously, significantly improves production efficiency, can not carry out hot pull and produces the magnesium alloy solder wire of diameter less than 4mm.

The magnesium alloy solder wire extrusion die schematic diagram that Fig. 1 adopts for the present invention with porous work zone.
Among Fig. 1,1 is patrix, and 2 is counterdie, and 3 is the porous work zone.
The magnesium alloy solder wire wire-drawing die schematic diagram that Fig. 2 adopts for the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is described further.
What the inventive method adopted is the magnesium alloy solder wire extrusion die with porous work zone, is on the magnesium alloy pipe Extrusion Porthole Die for Aluminium Profiles basis of routine, the work zone between the upper and lower mould is designed to have the porous work zone that aperture size is 1~4mm, as shown in Figure 1.Fig. 1 is the vertical view of magnesium alloy solder wire extrusion die, and the porous work zone 3 between patrix 1 and the counterdie 2 has many holes to constitute, and aperture size is 1~4mm.
The inventive method adopts a magnesium alloy solder wire wire-drawing die corresponding with shape aperture, porous work zone simultaneously, the wire-drawing die planform as shown in Figure 2, the aperture size of aperture is corresponding with the porous work zone of magnesium alloy solder wire extrusion die with distribution in the wire-drawing die.
Below be that the AZ31 magnesium alloy solder wire of 1.5mm is an example to produce diameter.Technical parameter among the embodiment does not constitute the qualification to technical solution of the present invention.
Step 1: by the welding wire external diameter of pipe that squeezes out is 40mm, gage of wire is 1.5mm, once push 82 magnesium alloy solder wire designs, adopt the magnesium alloy pipe Extrusion Porthole Die for Aluminium Profiles, work zone between the upper and lower mould is designed to have the porous that aperture size is 1.5mm (82 holes) work zone, constitutes the magnesium alloy solder wire extrusion die; Design a wire-drawing die simultaneously, the aperture size of aperture is corresponding with the porous work zone of magnesium alloy solder wire extrusion die with distribution in the wire-drawing die.
