Description
Technical field
The present invention relates to guard rail technical field, particularly a kind of composite die casted pedestal for aluminium alloy guard rail.
Background technology
Now, urban road, square periphery, guard rail progress is widely used in critical facility and place around building etc.
Isolation, protection, shunting.Guard rail should isolated crowd also to isolate vehicle, should prevent from being pushed over by crowded crowd, also to prevent
The collision of vehicle, vehicle in even running at high speed is not intended to or intentional collision, and this impact strength to guard rail proposes
Very high requirement.
If guard rail goes for very high impact strength, guard rail itself have to possess and have enough weight, with
Static potential energy caused by own wt resists the dynamic kinetic energy of alluvium, so just can ensure that alluvium can not break through guard rail
The defence line formed, and a very big part for guard rail own wt is exactly guard rail pedestal.
The material of existing metal protection column pedestal has concrete, husky cast iron matter, stainless steel etc..Concrete pedestal passes through thick
Rough mould molding, its rough surface, out-of-flatness is smooth, can not make the concavo-convex moulding of exquisiteness, and frangible, defence system
Number is not high, it is impossible to reuses, non-recovery value, is unfavorable for environmental protection.Husky cast iron matter pedestal is by husky mould cast molding, because of its system
Technique is made to determine its rough surface, have husky hole, it is necessary to which secondary polishing and machinery are reprocessed, and easily produce rust in the environment
Mark and influence outward appearance, its production efficiency is extremely low and causes environmental pollution.Stainless steel cost is very high, thus thickness typically compares
It is thin, weight and protection low intensity are caused, if just higher using the thicker stainless steel of thickness, cost.
Aluminum alloy material be it is a kind of be easily worked, surface can process many smooth pattern patterns attractive in appearance, Bu Huisheng
Rust, the cost material more much lower than stainless steel, simply the weight of aluminum alloy material and intensity are relatively low, and simple aluminum alloy material is not
Suitably with the very high city guard rail pedestal of protection intensity requirement；And only with aluminum alloy material come if doing pedestal,
Aluminium alloy pedestal occurs that surface is caved in phenomenon, has had a strong impact on aesthetic property because volume is larger in moulding process.
The content of the invention
It is an object of the invention to provide a kind of surface using aluminum alloy material production and processing shell, make pedestal integral surface
It is smooth it is attractive in appearance, will not get rusty, high hardness, weight weight, high protection intensity requirement, lower-cost compound pressure are met using steel core again
Cast pedestal.
The present invention solve its technical problem solution be：
A kind of composite die casted pedestal for aluminium alloy guard rail, the composite die casted pedestal wrap by Al-alloy casing 1 and completely
The steel core 2 being rolled in Al-alloy casing 1 forms, and the steel core 2 is hollow prismatoid or square ring body, the Al-alloy casing 1
Lower half be hollow square ring body, the first half of Al-alloy casing 1 is hollow prismatoid, the upper surface of Al-alloy casing 1
Portion is provided with the ring interface 1-1 to match with the bottom of the column of aluminium alloy guard rail.
Further, the top of the composite die casted pedestal is additionally provided with aluminium alloy decorative side's ring body 3, the aluminium alloy
The ring interface 1-1 of the upper end face of the embedded Al-alloy casing 1 of the matching set of the side's of decoration ring body 3 and with the column of aluminium alloy guard rail
Bottom match engagement.
A kind of method for manufacturing the composite die casted pedestal for aluminium alloy guard rail, the processing step of this method are：1. lead to
Cross cast steel and steel core is made；2. steel core is put into aluminium die casting inner chamber into simultaneously supporting and fixing, then injected into aluminium die casting
HTHP liquid aluminium alloy, cooling, the demoulding, shaping, turns into composite die casted pedestal.
Compared with the prior art, the present invention has following remarkable result：
<1>Present invention employs the composite die casted base construction of the fully wrapped around internal layer steel core of top layer Al-alloy casing and manufacturer
The advantages of method, and weight hard using the steel core of composite die casted pedestal internal layer are big, in conjunction with the Al alloy shell of outer layer die casting parcel
Attractive in appearance, the anti-rust action that body plays, so that guard rail is attractive in appearance indeformable, also considerably increase the weight of guard rail.
<2>And there is the hard steel core of internal layer as support so that the Al-alloy casing of outer layer composite die casted will not be sent out
The problem of raw surface is caved in.
<3>And can with the volume, the weight that increase in actual environment to the change of impact strength, subtract steel core, and
Even and if internal layer steel core volume increase, subtract after can also keep multiple by the thickness for the Al-alloy casing for subtracting, increasing outer layer composite die casted
Close diecast base overall appearance, constancy of volume.
The present invention is applied widely, is applicable to the aluminium alloy compound guard rail of various moulding.
