Abstract
The present invention relates to a kind of extrusion type mould for making rods and bars of aluminium alloy, including mould, die-cushion and deflector；The die-cushion is provided with recipient, the deflector is provided with pod apertures, the mould is provided with the diversion chamber of connection recipient and pod apertures, the entrance of the pod apertures deviates mold center, circulating cooling aquaporin is provided with around the recipient, the axis of the pod apertures is 30 60 degree with the angle of the axis of recipient.The mould can avoid the occurrence of coarse-grain in extruding manufacture rods and bars of aluminium alloy.
Description
Technical field
The present invention relates to a kind of extrusion type mould for making rods and bars of aluminium alloy, belong 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 small, 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 are 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 the above-mentioned technical problem, technical scheme proposed by the present invention is：A kind of extrusion for making rods and bars of aluminium alloy
Pattern has, including mould, die-cushion and deflector；The die-cushion is provided with recipient, and the deflector is provided with pod apertures, described
Mould is provided with the diversion chamber of connection recipient and pod apertures, and the entrance of the pod apertures deviates mold center, the recipient
Around be provided with circulating cooling aquaporin.
Preferably, the axis of the pod apertures and the angle of the axis of recipient are 30-60 degree.
The beneficial effect that the present invention brings is：Increase deformation extent by improving extrusion coefficient in the present invention most direct
Mode is exactly the extruder for selecting internal diameter of the container larger, but this equally will greatly increase the size of mould and the energy of extrusion process
Consumption.Length by extending pod apertures of the invention, this increased extruding system indirectly equivalent to the internal diameter for increasing recipient
Number.Therefore, using this structure, the generation of coarse-grain can be avoided, while the potential of extrusion equipment can be given full play to.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Embodiment
The extrusion type mould of the making rods and bars of aluminium alloy of the present embodiment, including mould 1, die-cushion 4 and deflector 2；The mould
Pad 4 is provided with recipient, and the deflector 2 is provided with pod apertures 3, and the mould 1 is provided with connection recipient with pod apertures 3
Diversion chamber, the entrance of the pod apertures 3 deviates mold center, and circulating cooling aquaporin is provided with around the recipient, described
The axis of pod apertures 3 is 30-60 degree with the angle of the axis 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 use equivalents are formed, is the protection domain of application claims.
