Description
Technical field
The present invention relates to automotive parts manufacturing technologies, and in particular to a kind of automobile front suspension lower control arm ontology and
Preparation method.
Background technique
Double fork arm type equal independent suspensions are remarkably improved the handling stability energy of vehicle, due to that need to occupy more chassis space and make
The high reason of valence, is typically employed on large and medium-sized vehicle and luxurious car, and front suspension lower control arm is double fork arm type equal independent suspensions
Important composition component.One end is connect by front suspension lower control arm ontology by bulb component with knuckle, and the other end passes through bulb
Component is connect with subframe, bears alternate stress in running car, needs very big lateral stiffness, while in jump of hanging down, system
Guarantee that workpiece is able to bear higher stress under four kinds of dynamic, turning, impact operating conditions, thus guarantee the stability of vehicle, comfort,
Safety.
At this stage, front suspension lower control arm ontology mostly uses greatly 40Cr material, is formed using hot forging process, by remaining after forging
Preferable comprehensive mechanical property is obtained after hot modifier treatment.The lower control arm bulk properties of technique preparation are more uniform, but adjust
Matter treatment process need to expend a large amount of electric power and working hour, and the use of quenching oil is also unfavorable for environmental protection.Due to double fork arm type equal independent suspensions
Lower control arm axial length is big, for guarantee part intensity and rigidity, on the body can the biggish curved surface of design angle, therefore
Quench after hot forging and easily deform during oil, subsequent corrective and processing are difficult to repair, and such as use anti-deformation tool, then increase at
This, while production efficiency can be reduced, it is not suitable for being produced in enormous quantities.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of automobile front suspension lower control arm ontology and its preparation sides
Method, using non-hardened and tempered steel as raw material, heated → blocking → heating → finish-forging → controll cooling after forging → trimming shaping → shot-peening →
Machine adds, and obtains front suspension lower control arm ontology.The preparation method is without carrying out quenched process, reducing energy consumption and saving work
When, it solves the problems, such as quenching distortion, reduces comprehensive production cost.
The technical scheme adopted by the invention is as follows:
A kind of preparation method of automobile front suspension lower control arm ontology, using non-hardened and tempered steel as raw material, the preparation method
The following steps are included: heating → blocking → heating → finish-forging → controll cooling after forging → trimming shaping → shot-peening → machine adds, front overhang is obtained
Frame lower control arm ontology.
The non-hardened and tempered steel includes the chemical element of following weight percent: C:0.42-0.49%, Si:0.30-
0.60%, Mn:1.20-1.50%, S:0.040-0.075%, Cr:0.10-0.30%, V:0.08-0.20%, Ti:0.02-
0.1%, Cu :≤0.1%, P:0-0.035%, surplus is Fe and inevitable impurity.In the ingredient of non-hardened and tempered steel be added vanadium,
Titanium, manganese, chromium microalloy element, the tiny carbide and nitride being precipitated in ferrite and pearlite can keep coherence with parent phase
Relationship is to make steel strengthen.The mechanical property of the steel grade reaches or approaches the steel grade by modifier treatment.
The non-hardened and tempered steel preferably comprises the chemical element of following weight percent: C:0.45%, Si:0.38%, Mn:
1.25%, S:0.048%, Cr:0.22%, V:0.12%, Ti:0.05%, Cu:0.07%, P:0.008%, surplus be Fe and
Inevitable impurity.
It is to guarantee non-hardened and tempered steel molding that heating and temperature control, which heats main purpose at 950-1050 DEG C, blocking, before blocking,
If the excessively high surface oxidation degree that can aggravate steel of temperature of heating, while energy consumption is improved, and temperature is too low, plastic deformation
It reduces, resistance of deformation increases, and malleability is deteriorated, and metal can also generate processing hardening and crack, therefore the present invention will be before blocking
Antipyretic temperature control at 950-1050 DEG C.
Heating and temperature control is at 1050-1190 DEG C before finish-forging, in order to make the microalloy element of precipitation strength incorporate austenite
In, workpiece need to be heated to higher temperature；When being heated to 1050 DEG C or more, austenite can perfect recrystallization；Work as heating temperature
When improving to 1190 DEG C or more, austenite grain can grow up, and roughening is significant；Decline so as to cause the toughness of steel；Surface Oxygen simultaneously
Change seriously, therefore, the present invention is by heating and temperature control before finish-forging at 1050-1190 DEG C.
The temperature of workpiece is controlled at 890 DEG C -940 DEG C after the completion of finish-forging, and forging stock is still in high temperature Austria in this way after forging finish-forging
Family name's body state, workpiece control it is cold before temperature at more than A3 line, austenite start to be changed into ferrite process can completely by
Control.
In the controll cooling after forging technique, cooled down by the way of air-cooled, cooling rate control 3.5 DEG C/s-5 DEG C/
S, carried out after workpiece is cooled to 520-620 DEG C it is air-cooled, cooling velocity will have a direct impact on micro alloying element precipitation strength effect
Fruit, when cooling velocity is lower than 3.5 DEG C/s, cooling velocity is excessively slow, and the coarse grains of pro-eutectoid ferrite, content of pearlite in alloy is few,
The strength of materials is unable to satisfy requirement, and with the increase of cooling velocity, the content of pro-eutectoid ferrite is gradually decreased, ferrite crystal grain
Refinement, the content of pearlite gradually increase, and the strength of materials and toughness are all preferable at this time, when cooling rate reaches 6 DEG C/s or more, can give birth to
It can increase with the increase of cooling velocity at the content of bainite, and bainite, although the toughness of bainite meeting reinforcing material,
But it will lead to the machinability decline of part, therefore comprehensively consider, cooling rate is arranged 3.5 DEG C/s-5 DEG C/s's the present invention
In range.
In the shot-blast process, shot peening strength 0.25-0.33Amm, shot-peening coverage rate is not less than 93%, in this way in addition to going
It descales outer, workpiece surface can be made to remain certain compression, improve the fatigue strength of workpiece.
The present invention also provides the automobiles that the preparation method using above-mentioned automobile front suspension lower control arm ontology is prepared
Front suspension lower control arm ontology.
The tensile strength of the vehicle front suspension lower control arm ontology is not less than 790MPa, and yield strength is not less than 720MPa,
Elongation after fracture is not less than 12%, and the contraction percentage of area is not less than 25%；Hardness number is 220-270HBS, same control arm difference position
Difference of hardness is set no more than 30HBS；Impact absorbing energy KU2(-40℃)≥31J。
The metallographic structure of the vehicle front suspension lower control arm ontology is pearlite+ferrite, and grain size is not less than 4.5 grades.
The present invention passes through the heating temperature before control blocking, finish-forging using the non-hardened and tempered steel of special component as raw material
Before with the type of cooling and cooling rate of heating temperature, controll cooling after forging later, and shot-peening is carried out after trimming shaping
Processing, obtains and has pearlite+ferritic structure automobile front suspension lower control arm ontology, with excellent mechanical property
And impact resistance.
Compared with prior art, the present invention is directly using non-hardened and tempered steel as the original of production automobile front suspension lower control arm ontology
