Problems solved by technology

However, in these technologies, the temperature of the billet and the mold is always maintained at about 400°C to 450°C during extrusion, and the magnesium alloy is semi-solid, and nitrogen is used to blow the exit of the extrusion die to prevent the billet from being blown, and it must be in a reasonable lubricant and other conditions. It can be completed under the conditions of hot extrusion and hot drawing combined process. The requirements for mold and extrusion machine are almost strict, the cost of extrusion is extremely high, the efficiency is extremely low, and it can only be extruded. low magnesium alloy
Since the magnesium alloy in the above-mentioned extrusion process is in a semi-solid state, a phase change will occur for a magnesium alloy with a high alloy content and the hot extrusion billet is easily oxidized. Relatively high cost and low efficiency

Embodiment

[0031] After the reciprocating extrusion of AZ91D magnesium alloy, it is continuously extruded into ф5mm magnesium alloy wire.

[0032] Material preparation Remelt and cast the industrial state AZ91D magnesium alloy ingot into a cylindrical ingot with a diameter 1mm to 2mm larger than the diameter of the inner hole of the extrusion cylinder, and then process the ingot into a diameter larger than that of the extrusion cylinder For a cylindrical ingot with a hole diameter of 0.2 mm, remove the processing oil and coat the side wall and upper surface with MoS 2 grease;

[0033] First, put the reciprocating extrusion device on the press, use the press to press the first half die 6 and the second half die 12 into the large extrusion barrel 7, and then press into the small extrusion barrel 2 for mold closing , the above-mentioned treated extruded AZ91D magnesium alloy ingot 8 is packed into the mold cavity surrounded by the large extrusion barrel 7, the small extrusion barrel 2, the...

Abstract

A continuous extruding method for preparing the Mg-alloy wire includes such steps as treating the surface of Mg alloy, loading it in the moulding cavity formed by big and small extruding cylinders, the first half of female die and the second half of female die, repeated extruding at 300-350 deg.C for fining its crystal grains and increasing its plasticity, loading it in a continuous extruder of wire material, and repeated extruding at 300-350 deg.C.

Description

technical field [0001] The invention belongs to the technical field of plastic forming of non-ferrous metals, and relates to an extrusion method of metal materials, in particular to a continuous extrusion method of magnesium alloy wire. Background technique [0002] Magnesium and magnesium alloys have significant advantages such as low specific gravity, high specific strength and specific stiffness, and low raw material prices, and have become the preferred materials for modern automobiles, electronics, communications and other industries. The production of welding products of various magnesium alloys requires a large amount of electrodes or wires prepared from magnesium alloy wires. Generally, welding wire can be produced by metal mold casting in small batch production, and can be produced by extrusion molding in large batch production. The conventional metal mold casting method for producing welding wire has simple procedures and low cost, but the production efficiency an...
