Abstract
The invention relates to a die for manufacturing aluminum alloy bars. The die for manufacturing aluminum alloy bars comprises a die body, a die cushion and a deflector, wherein a squeezing drum is arranged on the die cushion, a deflector hole is formed in the deflector, and the deflector hole and the squeezing drum are arranged in an eccentric mode. The die can avoid coarse crystals while manufacturing the aluminum alloy bars through squeezing.
Description
Technical field
The present invention relates to a kind of mould for making rods and bars of aluminium alloy, belongs to machine-building processing technology field.
Background technology
Traditional rods and bars of aluminium alloy mode of production is the center fashion of extrusion using forward extrusion, i.e. type hole in mould
The heart is simultaneously coincided 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 a kind of 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 mould for making rods and bars of aluminium alloy,
Including mould, die-cushion and deflector；The die-cushion is provided with recipient, and the deflector is provided with pod apertures, the pod apertures
With recipient eccentric setting.
Preferably, the water conservancy diversion bore edges are more than 20mm with the distance of recipient inwall.
The beneficial effect that the present invention brings is：As the metal from nib distalmost end is big into the resistance of nib in the present invention
Improve greatly, this increased extrusion coefficient indirectly equivalent to the internal diameter for increasing recipient.Therefore, using this structure, can
The generation of coarse-grain is avoided, while the potential of extrusion equipment can be given full play to.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Embodiment
The mould of the making rods and bars of aluminium alloy of the present embodiment, including mould 1, die-cushion 2 and deflector 3；Set on the die-cushion 2
There is recipient 5, the deflector is provided with pod apertures 4, the pod apertures 4 and 5 eccentric setting of recipient.
Preferably, 4 edge of the pod apertures is more than 20mm with the distance of 5 inwall of recipient.
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.
Claims (2)
