Abstract
The invention relates to a die of an aluminium alloy bar. The die comprises a die core, a die backer and a deflector, wherein an extrusion container is arranged on the die backer; a diversion hole is formed in the deflector; the diversion hole and the extrusion container are eccentrically arranged; the diversion hole is a stepped diversion hole; and the farther from the die backer the stepped diversion hole is, the larger the opening of the stepped diversion hole is. According to the die, coarse grains can be avoided during extrusion manufacturing of the aluminium alloy bar.
Description
Technical field
The present invention relates to a kind of aluminum alloy rod bar mould, belongs to machine-building processing technology field.
Background technology
Traditional rods and bars of aluminium alloy mode of production is in mould using the center fashion of extrusion of forward extrusion, i.e. type hole
The heart simultaneously coincides with the center of recipient.Simply, deformation degree of extrusion is little, and extruding force is low, no to adopt Making mold in this way
Foot part is that the grain size of section bar is big, coarse-grain phenomenon easily occurs, and the mechanical property and conductance for being obtained is relatively low.
The content of the invention
The invention solves the problems that technical problem is:Overcome the shortcoming of above-mentioned technology, there is provided one kind extruding manufacture rods and bars of aluminium alloy
When avoid the occurrence of the mould of coarse-grain.
In order to solve above-mentioned technical problem, technical scheme proposed by the present invention is:A kind of aluminum alloy rod bar mould, including mould
Son, die-cushion and deflector, the die-cushion is provided with recipient, and the deflector is provided with pod apertures, the pod apertures and extruding
Cylinder eccentric setting, the pod apertures be staged pod apertures, the staged pod apertures from die-cushion more away from then its opening it is bigger.
Preferably, the series of the ladder of the staged pod apertures is 2~5 grades.
The beneficial effect that the present invention brings is:Pod apertures or diversion chamber in the present invention on deflector adopt stepped-style,
The thickness of deflector can obtain more relatively large, and the series of ladder can be with 2~5 grades, and adjacent steps aperture differs 4~10mm,
The rigid region in extrusion process can so be increased, increase resistance during deformation, make metal through multiple predeformation, be carried
High extruding force.In extrusion process, compression can reduce the diffusion velocity of tissue, and the more big then diffusion velocity of compression is less
So as to suppress growing up for crystal grain, and then obtain good surface quality and fine and close interior tissue, it is to avoid coarse-grain occur.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Embodiment
The aluminum alloy rod bar mould of the present embodiment, including mould 1, die-cushion 2 and deflector 3, the die-cushion 2 is provided with extruding
Cylinder 5, the deflector 3 is provided with pod apertures 4, the pod apertures 3 and the eccentric setting of recipient 5, and the pod apertures 4 are staged
Pod apertures, the staged pod apertures from die-cushion 2 more away from then its opening it is bigger.
Preferably, the series of the ladder of the staged pod apertures is 2~5 grades.
The present invention is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the present invention may be used also
To there is other embodiment.The technical scheme that all employing equivalents are formed, is the protection domain of application claims.
