Description
Technical field
The present invention relates to engine link manufacturing field, more particularly to a kind of manufacture method of Stainless-steel fibre aluminum connecting rod.
Background technology
At present, Machining of Connecting Rod is a kind of typical part processing in manufacturing technology.Connecting rod is by connecting rod cap and shaft group
Into, and be combined together connecting rod cap and shaft by screw, its stub end is generally connected with bent axle, and small head end passes through piston pin
It is connected with piston, the gas pressure that will act on piston passes to bent axle, the reciprocating motion of piston is changed into the rotation fortune of bent axle
It is dynamic.At work, the size and Orientation for driving the gas pressure of reciprocating motion of the pistons is all mechanical periodicity to connecting rod, same with this
When, the pressure of gas produces very big compression stress and collapsing stress in shaft, connecting rod is born larger tension, institute
With connecting rod be subject to be shock feature dynamic loading, it is therefore desirable to connecting rod is in light weight, intensity will get well.
The main manufacture methods of connecting rod blank have casting, die forging and powder metallurgy at present, and cast connecting rod has flexible design,
Connecting rod finished size is closely sized to, processing characteristics is good, reliable operation and low cost and other advantages, is increasingly carried as casting is horizontal
High and cost continuous reduction, cast connecting rod are widely used on full-sized car.
In Chinese patent literature disclosed " the antigravity extrusion casint device and manufacture method of a kind of aluminum alloy connecting rod ",
Its notification number is CN102615268A, and the day for announcing is August in 2012 1, and this application case discloses a kind of to be extruded using antigravity
The method and mould of casting technique manufacture aluminum alloy connecting rod, the specifically a kind of manufacture method and mould of cracking type aluminum connecting rod,
Its technical scheme is to be built into suitable foil in mould in advance, and aluminum melt fills type to extrude cast-type, passes through spreader pair
Shunting and control, aluminium liquid enter die cavity from bottom to top, and foil both sides liquid level synchronously rises, and make to form cracking circle in connecting rod casting
Face.Screw mechanism is set on the mould, the gap between gonnecting rod body die cavity and connecting rod cap die cavity involutory surface is adjusted, is easy to place
With changing foil.When ensureing that connecting rod is cast with apparatus and method of the present invention the cracking interface that is formed its major part prejudge area it
It is interior, avoid connecting rod subsequently cracking process in cracked bifurcated or cracking face skew the defects of, make casting without volume gas, nothing
Cold shut, without owing to pour, tissue tight, can be heat-treated, its mechanical property and mechanical performance significantly improve.The deficiency of the invention
Although part, which is aluminum alloy materials, has many advantages, such as light weight, corrosion-resistant, formability is good, aluminium alloy is brittle
Property material, tensile strength is low close to yield strength, poor toughness, hardness, not wear-resisting, not impact resistance, and the coefficient of heat conduction is larger, thermal change
Shape is big, and heat endurance is poor, it is impossible to improves the mechanical strength of material by being heat-treated.
The content of the invention
The present invention is in order to overcome the shortcomings of aluminum connecting rod poor toughness, easy fracture in the prior art, there is provided a kind of fatigue strength
The Stainless-steel fibre aluminum connecting rod high with bending strength.
To achieve these goals, the present invention uses following technical scheme：
A kind of manufacture method of Stainless-steel fibre aluminum connecting rod, including：A, first stainless steel fibre is bonded to be formed not by binding agent
Become rusty steel fibre prefabricated component, stainless steel fibre prefabricated component is preheated to the mould for being preheated to 500 DEG C ~ 800 DEG C is put into after 500 DEG C ~ 800 DEG C
In tool, then the aluminium alloy melt that temperature is 700 ~ 800 DEG C is poured into, is forced into 70 ~ 100MPa, is ejected after material is fully cured,
Obtain the connecting rod blank that connecting rod cap and shaft are integrated；B, roughing is carried out to connecting rod blank, and processes connecting rod cap and shaft
Bolt hole；C, broached out groove in the split position of crank pin end pore, two pieces of semicircles are then put into big end hole and are formed
Type part, two pieces of semicircle molding part centres form a wedge-shaped slot, finally insert in the wedge-shaped slot wedge, make company
Bowl cover and shaft separate；D, semifinishing and finishing are carried out to connecting rod workpiece.
As a preferred technical solution of the present invention, the speed pressurizeed in the step a is 1 ~ 3cm/s.
As a preferred technical solution of the present invention, the stainless steel fibre prefabricated component is arranged on the position of connecting rod shank
Put.
As a preferred technical solution of the present invention, the surface of the stainless steel fibre is provided with some holes.
The beneficial effect that is reached of the present invention is compared with prior art：Using die cast process, connecting rod structure refinement, nothing
Stomata, the die casting than common metal die casting function admirable can be obtained, extrusion process equipment is simple, cost is low, material
Quality is high and stably, is easy to industrialized production；Aluminum alloy materials can significantly reduce connecting rod weight, by the way that stainless steel fibre is prefabricated
Part die casting becomes connecting rod blank, by fibre strengthening, is greatly improved connecting rod to the connecting rod shank using aluminium alloy as matrix
Fatigue strength and bending strength under high temperature；Connecting rod cap and shaft are separated using the above method, metal fragment will not be produced, kept away
Exempt from the processing to metal fragment, and optimize Workshop Production environment.
