Abstract
The utility model discloses a magnesium alloy rod extrusion die, including mould main part (1) and mould pressure head (2), the inside extrusion channel that is equipped with of extrusion die, extrusion channel include from last to down consecutive storage cavity (3), reduce section (4), S type extrusion section (5) and straight line extrusion section (6), arbitrary cross section of S type extrusion section (5) all is circularly, and is close to the demolding end more, and the diameter of this cross -section circle is more little, S type extrusion section (5) minimum curvature radius A in upper end or the curvature radius of B department are 50 -80mm, minimum curvature radius C of S type extrusion section (5) lower extreme or D curvature radius are 90 -120mm. The utility model discloses a magnesium alloy rod extrusion die can form shear stress in the pressure process in the magnesium alloy to reduce the base face texture in the extrusion process, improve the performance of extrusion rod.
Description
Technical field
The utility model belongs to field of magnesium alloy, relates to a kind of magnesium alloy extrusion mould, particularly a kind of mould of Non-symmetric Extrusion magnesium alloy rod.
Background technology
The technologic material that during magnesium alloy, current commercial Application is the lightest, have that quality is light, intensity is high, good processability, dimensional stability are high, shock resistance, the advantage such as wear-resistant, plastics, ferrous materials can be replaced, meet product light, thin while do not affect its intensity, have broad application prospects.
Magnesium alloy has close-packed hexagonal structure, and its plastic deformation is comparatively difficult, and therefore magnesium-alloy material is in the majority with foundry goods at present, but as-cast magnesium alloy mechanical property is poor, can not meet market demand.Therefore, study magnesium alloy deformation mechanism and develop corresponding wrought magnesium alloy and become a kind of trend.The mode that current magnesium alloy adopts common symmetric to extrude usually carries out moulding processing, but this symmetrical fashion of extrusion gained magnesium alloy plate basal plane texture is serious, larger on plate property impact.Therefore, be necessary from a kind of novel magnesium alloy extrusion die of research and development, to reduce the basal plane texture produced in magnesium alloy extrusion process.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of magnesium alloy rod extrusion die.
For achieving the above object, the utility model provides following technical scheme:
A kind of magnesium alloy rod extrusion die, comprise die main body and die head, described extrusion die inside is provided with squeezing passage, described squeezing passage comprises storage cavity connected successively from top to bottom, tightens section, S type extruded segment and lineal extrusion section, arbitrary cross section of described S type extruded segment is all rounded, and the closer to depanning end, this cross section diameter of a circle is less.
As preferably of the present invention, described S type extruded segment upper end minimum profile curvature radius A is or/and B place radius of curvature is 50-80mm, and described S type extruded segment lower end minimum profile curvature radius C is or/and D radius of curvature is 90-120mm.
As preferably of the present invention, described storage cavity cross-sectional diameter is 10-30 times of lineal extrusion section diameter of section.
The beneficial effects of the utility model are:
Magnesium alloy rod extrusion die of the present utility model, by arranging S type squeezing passage in squeezing passage, can form shear stress in pressure process in the magnesium alloy, thus reduces the basal plane texture in extrusion process, improves the performance of extruded bars; The present invention further discloses radius of curvature and each section of diameter of S type extruded segment, avoid stress in extrusion process too to concentrate adverse effect.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the structure chart of embodiment 1 magnesium alloy rod extrusion die.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the present embodiment is described in detail.
Embodiment 1:
As shown in Figure 1, a kind of magnesium alloy rod extrusion die of the present embodiment, comprise die main body 1 and die head 2, described extrusion die inside is provided with squeezing passage, described squeezing passage comprises storage cavity 3 connected successively from top to bottom, tightens section 4, S type extruded segment 5 and lineal extrusion section 6, arbitrary cross section of described S type extruded segment 5 is all rounded, and the closer to depanning end, this cross section diameter of a circle is less.
In the present embodiment, described S type extruded segment upper end minimum profile curvature radius A is or/and B place radius of curvature is 50-80mm, and described S type extruded segment lower end minimum profile curvature radius C is or/and D radius of curvature is 90-120mm.
In the present embodiment, described storage cavity 3 cross-sectional diameter is 10-30 times of lineal extrusion section 6 diameter of section.
During extruding, magnesium alloy ingot is priority reduced diameter after storage cavity 3, deflation section 4, S type extruded segment 5 under the effect of die head 2, and left back entering after lineal extrusion section 6 extrudes aligning must break into product; Adopt the present embodiment pressurizing unit gained magnesium alloy plate texture comparatively light, comprehensive mechanical property is obviously promoted.
The magnesium alloy rod extrusion die of the present embodiment, by arranging S type squeezing passage in squeezing passage, can form shear stress in pressure process in the magnesium alloy, thus reduces the basal plane texture in extrusion process, improves the performance of extruded bars; The present invention further discloses radius of curvature and each section of diameter of S type extruded segment, avoid stress in extrusion process too to concentrate adverse effect.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
