Abstract
The invention provides aluminum alloy liquid die forging manufacturing process for parts of electrified high-speed railway contact nets. The aluminum alloy liquid die forging manufacturing process comprises steps of smelting aluminum alloy raw materials, simultaneously preparing a die and carrying out preheated die assembly; pouring aluminum liquid; applying pressure; carrying out die sinking and taking out a part; and the like. The characteristic that liquid flows and is formed easily when metal is cast is utilized, the process is combined with hot die forging technology, the metal liquid flows and is formed in a cavity of the die, is crystallized and solidified under the effect of the high static pressure and plastically deforms, shrinkage cavities and shrinkage porosities formed due to contraction and solidification contraction of liquid metal are forcedly eliminated, and various liquid die forged parts without any casting defects are obtained. The aluminum alloy liquid die forging manufacturing process has the advantages that defects generated by casting process can be removed, mechanical strength of a product is improved, products with complicated geometric shapes which cannot be processed by common die forging process can be produced, accordingly, service performances of the products are improved, energy consumption is greatly reduced, and energy is saved.
Description
Technical field
What the present invention relates to is a kind of aluminum alloy melt morphotype forging fabrication technique that is used for the electrified high-speed railway elements of contacting net, belongs to technical field of machining.
Background technology
At present; Electrified high-speed railway elements of contacting net product adopts casting technique or the manufacturing of metal pattern forging process usually; The product that adopts casting technique to produce is easy to generate shrinkage cavity, shrinkage porosite, microstructure coarsening; Defective is many, is unfavorable for the raising of mechanical strength, can not guarantee the traffic safety requirement of bullet train; And adopt contour forging technique production can't accomplish than the product of complicated geometry some, and energy resource consumption is bigger.
Summary of the invention
The technical problem that the present invention will solve is: in order to overcome above-mentioned technical problem; A kind of aluminum alloy melt morphotype forging fabrication technique of electrified high-speed railway elements of contacting net is provided; The defective raising product mechanical strength that casting technique produces can be eliminated, and the product of complex geometric shapes can be produced.
Technical scheme: a kind of aluminum alloy melt morphotype forging fabrication technique of electrified high-speed railway elements of contacting net, concrete contour forging technique step is following:
A) melting of aluminium alloy stock is prepared and preheating mould simultaneously;
B) matched moulds;
C) aluminium water cast;
D) exert pressure;
E) die sinking pickup.
Described melting may further comprise the steps:
A) preparation before the fusing;
B) charging;
C) heat fused;
D) aluminium crystal refining;
E) detect, adjust composition;
F) adjustment furnace temperature;
G) heat preservation for standby use.
Said cast comprises slow shot and fast shot, and slow shot pressure is 12 MPas, and slow shot speed is the 0.2-0.4 metre per second (m/s); Fast shot speed is the 0.8-1 metre per second (m/s); The whole injection time is 6-8 second; The time that keep-ups pressure is 12-14 second.
Aluminium water pouring temperature: 660 ℃; Mold preheating temperature: 180 ℃; Mould continuous operation temperature: 200-220 ℃.
It is 750 ℃ that said aluminium crystal refines temperature, and the aluminium crystal refines the time: 15 minutes.
Beneficial effect: can eliminate the defective raising product mechanical strength that casting technique produces; And can produce the product of the complex geometric shapes that contour forging technique can't process; Therefore not only improved the serviceability of product, and bigger reduction energy consumption, practiced thrift the energy.

Fig. 2 is the fusion process sketch map.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer, carry out detailed description in the face of the preferred embodiments of the present invention down.
A kind of aluminum alloy melt morphotype forging fabrication technique of electrified high-speed railway elements of contacting net, concrete contour forging technique step is following:
A) melting of aluminium alloy stock is prepared and preheating mould simultaneously;
B) matched moulds;
C) aluminium water cast, said cast comprises slow shot and fast shot, and slow shot pressure is 12 MPas, and slow shot speed is the 0.2-0.4 metre per second (m/s); Fast shot speed is the 0.8-1 metre per second (m/s); The whole injection time is 6-8 second; Aluminium water pouring temperature: 660 ℃; Mold preheating temperature: 180 ℃; Mould continuous operation temperature: 200-220 ℃;
D) exert pressure, the time that keep-ups pressure is 12-14 second;
E) die sinking pickup.
Described melting may further comprise the steps:
A) preparation before the fusing;
B) charging;
C) heat fused;
D) aluminium crystal refining, it is 750 ℃ that said aluminium crystal refines temperature, the aluminium crystal refines the time: 15 minutes;
E) detect, adjust composition;
F) adjustment furnace temperature;
G) heat preservation for standby use.
The aluminum alloy melt morphotype forging fabrication technique of electrified high-speed railway elements of contacting net is the compound of foundry engieering and hot forging technology.The liquid flow forming that is prone to was easy to characteristics when the present invention utilized metal casting; In conjunction with the hot forging technology; Make molten metal flowing forming in mold cavity, and under bigger static pressure effect crystallization and freezing, and produce plastic deformation; Forcibly eliminate because of metal liquid contraction, the formed shrinkage cavity of solidification shrinkage and shrinkage porosite, to obtain the various liquid forging parts of no any casting flaw.Therefore the liquid forging part is compared with foundry goods, is easy to eliminate casting flaw; Compare with the hot-die forging, be shaped easily, required plastic force is little, and promptly the aluminum alloy melt morphotype forging fabrication technique of electrified high-speed railway elements of contacting net has made full use of the strong point of casting technique and hot forging technology, has also remedied the deficiency of these two kinds of technologies simultaneously.Adopt the elements of contacting net product of aluminum alloy melt technology of Liquid Die Forging manufacturing that casing seat, sleeve ears, sleeve pipe monaural, rotation ears, positioning pipe ears, positioning support, Messenger Wire base etc. are arranged.
