Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Step 1: Using hot work die steel to make such as figure 1 Middle extrusion cylinder (1), extrusion die (3), hot extrusion shaft (4), cold extrusion shaft (5), support pad (7), base (8). Make adjustable heat preservation cylinder (6), prepare graphite sheet (9), nitrogen.

[0014] Step 2: melting and casting the industrial state magnesium alloy into a cylindrical ingot with a diameter 1-2 mm smaller than that of the inner hole of the extrusion cylinder, taking out the surface oxide layer, and wrapping the side wall and the upper surface with graphite sheets.

[0015] Step 3: If figure 1 , Put the extrusion die, magnesium ingot (together with the graphite sheet), and the hot extrusion shaft into the extrusion barrel in sequence, compact and ensure that the bottom surface of the extrusion die is aligned with the bottom surface of the extrusion bar...

Abstract

The continuous extrusion method of magnesium alloy wire is characterized by that the extrusion shaft is divided into heat extrusion shaft and cold extrusion shaft, and said continuous extrusion method includes the following steps: successively placing the compression die, magnesium alloy ingot covered with graphite flake and heat extrusion shaft into extruding cylinder, compacting, placing the extruding cylinder into electric furnace together with supporting pad, heating to 500-550 deg.C, heat-insulating for 30 min., at the same time of insulating heat preheating base to 200-300 deg.C, preheating heat-insulating cylinder to 400-450 deg.C, then taking out extruding cylinder together with supporting pad and placing them on the base, covering with heat-insulating cylinder, placing the cold extrusion shaft on the heat extrusion shaft, extruding on extruder.

Description

technical field [0001] The invention belongs to the technical field of plastic forming of non-ferrous metals, and relates to a continuous extrusion method of magnesium alloy wires. Background technique [0002] At present, the application of magnesium alloy is still not widespread. The production of magnesium alloys is mainly concentrated on a small number of profiles such as magnesium alloy tubes or bars. However, the production of magnesium alloy wire has not yet matured process methods. In particular, there is no process for preparing continuous magnesium alloy wires (up to hundreds of meters or thousands of meters). Contents of the invention [0003] The purpose of the present invention is to provide a continuous extrusion method of magnesium alloy wire. Magnesium alloy wires up to hundreds of meters or thousands of meters can be successfully prepared by this method. [0004] The technical scheme of the present invention is: the extrusion shaft is divided into a ho...
