Abstract
The invention discloses a forging processing technology of the forging class of the machinery class of a processing technology for producing large and large-diameter aluminum alloy forgings. The processing technology is characterized in that an aluminum alloy forging material is utilized for replacing the materials such as steel, copper, magnesium, wood, plastic and the like, and a series of forgings with excellent properties are obtained. Meanwhile, certain traditional production technologies and production conditions are changed. The aluminum alloy forgings are widely applied to the fields of aerospace, automobile, naval vessels and ships, energy power, electronic communication, machinery electrical equipment, petrochemical industry, metallurgy mines, weapon industry and the like.
Description
The present invention relates to a kind of forge piece processing technology that is used for producing the mechanical forging class of large-scale and large diameter aluminium alloy forging processing technology.
At present a large amount of steel forgings and copper forging of producing and using are characterized in that density is big, and specific strength and specific stiffness are less, hear resistance, electric conductivity, non magnetic and anticorrosive property is also relatively poor.
Along with current high-tech development, modern industry such as Aero-Space, Rail Highway, naval vessels boats and ships, weapon industry etc. develop towards high speed, lightweight direction.But do not satisfy these actual requirements at employed steel forgings of modern industry and copper forging.
The purpose of this invention is to provide a kind of processing technology that can replace the material of large-scale steel forgings and copper forging, make the forging of production, littler than steel forgings and copper forging density, specific strength and specific stiffness are big, hear resistance, electric conductivity, non magnetic and anticorrosive property is strong, to satisfy current high-tech development, satisfy the employed forging requirement of modern industry.The invention solves large-scale and large diameter aluminium alloy forging and in process, be easy to generate the technology difficult problem of cracking.
The object of the present invention is achieved like this, with large-scale and large diameter aluminium alloy forging processing technology, changes traditional steel forgings and copper forging processing technology.It is the aluminum alloy forge piece material that is up to the standards that will enter factory, intercept required blank with band mill, send into heating in the electric furnace again, kind and characteristic according to aluminum alloy blank, control different heating-up temperatures, and in stove, be incubated certain hour, make crystal grain carry out a series of physics and chemical change, to improve the physical property and the chemical property of blank.After blank after heating, being incubated is come out of the stove,, on forging machine, put down material, forge into specific thickness, deliver to again and expand the upward reaming of circle hammer, diffuse into and require size, put down material again, so repeatedly, expand i.e. forging moulding through three flat three according to design drawing and customer requirements.The moulding forging is delivered to engineering shop, again through car, dig, mill, after the operation such as brill, the aluminum alloy forge piece finished product.The aluminum alloy forge piece finished product after testing, after the assay was approved, finished product can be transported outward sale behind packing warehouse-in.
Below in conjunction with drawings and Examples to inventing large-scale and large diameter aluminium alloy forging processing technology is described further.
Among the figure: Fig. 1 is large-scale and large diameter aluminium alloy forging processing technology figure
Among the figure: 1, aluminium alloy stock; 2, blanking and check; 3, blank heating; 4, insulation; 5, forging; 6, machining; 7, finished product; 8, check; 9, packing; 10, warehouse-in; 11, sell.
Be to advance the aluminum alloy forge piece material (1) that is up to the standards of factory among the figure, intercept required blank (2) with band mill, (3) blank is sent into heating in the electric furnace, kind and characteristic according to aluminum alloy blank, control different heating-up temperatures, (4) are incubated certain hour in electric furnace, make crystal grain carry out a series of physics and chemical change, to improve the physical property and the chemical property of blank, (5) after the blank behind the heat tracing is come out of the stove,, on forging machine, carry out forging according to design drawing and customer requirements, forge into specific thickness, deliver to again and expand the upward reaming of circle hammer, diffuse into and require size, on forging machine, carry out forging again, so repeatedly, through three flat three expansions, i.e. forging moulding, (6) deliver to engineering shop with the moulding forging, pass through car again, dig, mill, after the operations such as brill, aluminum alloy forge piece finished product (7), (8) check, (9) qualified finished product packing, (10) warehouse-in, (11) are prepared outward transport and are sold.
According to different forging and customer requirements, take different processing technologys and equipment, can obtain various aluminum alloy forge piece product.
The aluminum alloy forge piece of Sheng Chaning in this way, density is little, has only 34% of steel casting, specific strength, specific stiffness and bigger than elastic modelling quantity, the fatigue resistance height, plasticity is good, and easily processing has good corrosion resistance, thermal conductivity, non magnetic.Interior tissue is fine and closely woven, even, zero defect, and surface treatment properties is good, and any surface finish is attractive and durable.
A series of good characteristics of aluminum alloy forge piece are for Alloy instead of Copper, copper, magnesium, timber and plastics provide good condition.Be widely used in Aero-Space, automobile, naval vessels boats and ships, energy source and power, electronic communication, mechanical electric apparatus, petrochemical industry, metallurgical mine, fields such as weapon industry.
