A kind of magnesium alloy profile continuous plastic processing forming die and forming method

Abstract

The invention relates to a continuous plastic processing forming die of a magnesium alloy sectional material and a forming method. The forming die comprises a base, a concave die, an extruding needle and an extruding rod, wherein the base comprises a base plate and support plates; the concave die is mounted on the two support plates; a forming hole is formed in the middle of the concave die; the extruding needle penetrates through the forming hole to be fixedly connected with the base plate; the extruding rod adopts a tubular structure, the lower end of the extruding rod sleeves the extruding needle from the upper end of the extruding needle, the inner wall of the extruding rod is clung to the extruding needle and the outer wall of the extruding rod is clung to the concave die; the forming method comprises the following steps: 1) fixedly mounting the forming die on an extruding machine; 2) heating the concave die to a certain temperature; 3) placing a hollow billet in the forming hole of the concave die; 4) driving the extruding rod through a moving die of the extruding machine to extrude the hollow billet. According to the continuous plastic processing forming die of the magnesium alloy sectional material and the forming method, the forming of magnesium alloy pipes is easier, the pipe structure and texture uniformity is improved, the industrial production is realized, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal forming, in particular to the field of forming ultra-fine light alloys or other fine-grained alloy profiles, and in particular to a continuous plastic processing forming mold and forming method for magnesium alloy profiles. Background technique [0002] In industrial production, pipes are mainly extruded through forming dies during production and processing; the traditional light alloy plastic deformation process includes multiple stages such as ingot preparation, ingot treatment, billet heating, and thermoplastic deformation. [0003] For the production and processing of ultrafine-grained alloy (light alloy) pipes, especially thin-walled and high-precision light alloy pipes, such as magnesium alloy thin-walled pipes, at present, forward extrusion is mainly used for forming; During the process, the magnesium alloy thin-walled pipe will form a banded structure along the extrusion directio...

Problems solved by technology

[0004] In view of the above-mentioned deficiencies existing in the prior art, the purpose of the present invention is to solve the problems that fine-grained and weak-textured magnesium alloy pipes are difficult to process, have poor molding quality, are not conducive to secondary processing, and are not suitable for industrial production. The magnesium alloy profile continuous plastic processing forming mold and forming method can make the forming of the magnesium alloy pipe easier, and can improve the uniformity of the structure of the pipe, thereby improving the forming quality of the magnesium alloy pipe, which is beneficial to subsequent processing, and can realize industrialization production, thereby increasing production efficiency
