Abstract
The invention relates to an extrusion casting method and equipment for aluminum alloy wheels, which use a general hydraulic press, a three-split mold (horizontal parting) with a diagonal draw bar and an ejection mechanism to realize automation of opening and closing of an intermediate mold and ejection of a cast piece, greatly simplify a hydraulic mechanism and reduce equipment cost. During casting, after the mold cavity is filled with molten aluminum, the mold cavity is slowly filled along the vertical direction for a long period of pressure maintaining time, so that the casting is solidified under high pressure and generates a small amount of plastic deformation, thereby obtaining a high-quality aluminum wheel and performing heat treatment strengthening.
Description
The present invention relates to the casting method of vertical die casting device, be few smear metal, the chipless technology that a kind of casting, forging are combined as a whole, also be a kind of make liquid metal at very high pressure effect lower charging type, solidify and produce a small amount of plastic deformation, thereby obtain the manufacture method of fine aluminum wheel.
Aluminum-alloy wheel (hereinafter to be referred as the aluminium wheel) is the main parts size on motorcycle, the automobile, and the main method of producing the aluminium wheel now has four kinds of low pressure casting, compression casting, sand mold gravitational casting, metal mold gravity castings etc.But sand casting surface quality and internal soundness are all poor; The aluminium wheel of existing compression casting, its inside exist serious pore, shrinkage porosite, can not heat-treat reinforcement; Low pressure casting and permanent mold casting are the main method of current domestic and international production aluminium wheel, though its quality is higher than sand casting and compression casting, in the specification requirement that still can not satisfy superior performance aluminium wheel aspect surface quality, internal soundness, mechanical performance, the production efficiency.
The objective of the invention is at above-mentioned existing problems of the prior art, provide a kind of and make that foundry goods Cheng Jingzhong bubble reduces, quality closely, chipless or few smear metal, will cast, forge the casting method that the aluminium that is combined as a whole is taken turns.They adopt extrusion casting method to produce the aluminum-alloy wheel of motorcycle, automobile with common vertical hydraulic press, and it has plurality of advantages such as high-quality, efficient, energy-conservation, low consumption, alloy material wide adaptability.
The solution of the present invention is three fens moulds that utilize the patrix by horizontal parting of common vertical hydraulic press additional known, middle mould, counterdie to form, only make simple hydraulic control and finish extrusion casint to aluminum-alloy wheel or similar foundry goods, this is a kind ofly to collect die casting and forge two kinds of casting methods that technology is the low speed heavy pressure of one.Feature of the present invention is to omit some specific hydraulic systems, only realize the motion of all moulds with common vertical hydraulic press, the plunger that has most importantly utilized common vertical hydraulic press liftout tank to rise has at a slow speed been realized liquid aluminium alloy is filled type at a slow speed to mold cavity.Also having an important feature in addition is exactly to be arranged after filling type one period long (15 seconds-60 seconds) dwell time finishing, add mould of the present invention and water road junction diameter bigger (equaling the diameter of reservoir substantially), so keep very meaningful than the long dwell time, can make its central runner mouth not prior to casting solidification, the material cake is later than again water the road junction and solidify.Realized two-in-one on die casting and the Forging Technology like this, the aluminum-alloy wheel dense structure that casting is come out, grain refinement, no needle-like tissue make product quality obviously be better than the aluminum-alloy wheel of producing with traditional die-casting technique.Also have, when die casting, fill type by horizontal direction, because the present invention has adopted and has filled type at a slow speed by vertical direction, make liquid aluminium alloy in filling the process of type, exempt the middle molten metal that exists of prior art (carrying out filling at a high speed type) and the eddy current type disturbance occurs air is involved in the liquid metal, make the shortcoming that produces the casting quality decline that pore caused in the foundry goods by horizontal direction.
The extrusion casting apparatus of aluminum-alloy wheel of the present invention includes general vertical hydraulic press and horizontal parting by patrix, three fens moulds that middle mould and counterdie are formed, included 1 in the mould in described three minutes) the control intermediate die entad does automatically or the brace mechanism 2 of centrifugal motion) aluminium liquid is filled type mechanism from what reservoir injected described three sub-model chambeies, it is characterized in that: a, one by charging ram, push pedal, the automatic ejecting mechanism of the foundry goods that push rod is formed, described charging ram is static with respect to hydraulic press, and be fixed with the push rod of stretching under the many vertical cantilever in the described movable push pedal, it passes the guide hole that is opened on patrix and the upper plate, but is relative motion with respect to upper plate and patrix; B, equal the reservoir diameter substantially at the described diameter that waters the road junction in the type mechanism that fills.Like this, when extrusion casint finishes, described push pedal and push rod rise together, when push pedal and static charging ram collide mutually, described push pedal and push rod are ejected casting finished products when guide pillar is done downward relative motion from patrix.
Increase and water the diameter at road junction, make material cake (being equivalent to prosperous mouthful) under pressure, implement to pounce on the effect of contracting foundry goods.This has embodied the characteristics of the present invention with die casting and forging and pressing " two-in-one ".
Also have, in order to realize that push rod and push pedal can set back automatically after casting finished products is ejected from mould, the present invention designs the anti-push rod that can realize this function, and it and described push pedal are fixed with one, it is stretched under the push pedal vertical cantilever, and servo-actuated is in the motion of push pedal.When patrix and counterdie are closed anti-push rod push pedal is pushed to upper, this moment all push rods also all servo-actuated be in upperly in push pedal, push rod and moving downward of push pedal have been reserved the room when so just being die sinking.
In the aluminum-alloy wheel extrusion casting method of the present invention, the temperature that is poured into the molten metal (aluminium alloy) that goes in the reservoir is preferably 680 ℃-750 ℃, and reservoir and mould are preferably by the temperature of top heat to 150-300 ℃.
Advantage of the present invention is: make 1. that aluminium alloy liquid steadily enters die cavity in the extrusion casint process in cavity filling process, do not have disturbance, can not be involved in air; 2. because the dwell time is long, make foundry goods in the process of extrusion casint, also continue to be subjected to being similar to the effect of forging and pressing, a small amount of plastic deformation takes place; 3. because gate diameter plays the feeding effect under the pressure greatly again, above-mentioned three characteristics have guaranteed that the performance of foundry goods is much higher than the performance of the foundry goods of producing with high speed die casting (prior art) method; 4. owing to design the ejecting mechanism that foundry goods can be ejected automatically and make the automatically reset resetting-mechanism of push rod after finishing extrusion casint, production efficiency is obviously improved.
