Abstract
The invention discloses a manufacturing method of a cross beam of an automobile instrument panel, and belongs to the field of non-ferrous metals. The manufacturing method adopts the following ingredients and manufacturing steps that (1) the cross beam of the automobile instrument panel comprises the following ingredients: 7.5 to 9.0 percent of Al, 0.2 to 0.6 percent of Mn, 0.15 to 0.4 percent of Zn, 0.4 to 0.8 percent of Zr and the balance Mg; (2) the cross beam of the automobile instrument panel comprises the following manufacturing steps of a, casting the cross beam of the automobile instrument panel and b, finely processing the cross beam of the automobile instrument panel. The manufacturing method solves the problems that the comprehensive performances such as density, specific stiffness and specific strength of materials used for manufacturing the cross beam of the automobile instrument panel are low, and has the advantages that the method is simple, the cost is low, and the processing is easy.
Description
Technical field
The invention belongs to non-metals field, more particularly, relate to a kind of manufacture method of Automobile instrument support crossbeam.
Background technology
Magnesium, due to its unique properties, becomes the third-largest metal engineering material after iron and steel, aluminium, is described as " 21 century green engineering material ".And magnesium alloy is widely used in the industries such as Aeronautics and Astronautics, the vehicle, weaving and printing because lower density, stiffness-to-density ratio and strength-to-density ratio are high.
Because magnesium alloy parts motional inertia is low, when being applied on high speed zero parts, effect is particularly evident.Magnesium alloy is used as auto parts and components and usually has the following advantages: (1) improves fuel economy comprehensive standard, reduce exhaust emission and fuel cost, according to measuring and calculating, what automobile was fuel used 60% is consumed in automotive dead weight, the every loss of weight 10% of automobile, oil consumption will reduce 8%-10%; (2) quality alleviates the delelivered payload capability and capacity weight that can increase vehicle, can also improve brake and acceleration capability simultaneously; (3) noise and vibration of vehicle can greatly be improved.
Fascia board girder is the load-carrying element supporting man-machine interface in automobile, and forms safety system together with other safety members, and can play the effect of chaufeur and passenger in protection car while supporting, its strength and stiffness is the important indicator of its performance.But usually owing to also needing to take into account the factors such as its weight, propose higher requirement to choosing of material, need the characteristic that lower density, stiffness-to-density ratio and strength-to-density ratio are high, magnesium alloy then can meet this demand well.
Summary of the invention
For density, the problem that the Combination property such as stiffness-to-density ratio and strength-to-density ratio is low of existing fascia board girder manufacture material, the invention provides a kind of manufacture method of fascia board girder, by changing the composition of magnesium alloy, make the density of material low, stiffness-to-density ratio and strength-to-density ratio high, thus reach the object of Combination property improving material.
For solving the problem, the present invention adopts following technical scheme.
A manufacture method for fascia board girder, its composition and manufacturing step as follows:
(1) composition of fascia board girder:
The percent by weight of fascia board girder is: Al:7.5-9.0%, Mn:0.2-0.6%, Zn:0.15-0.4%, Zr:0.4-0.8%, and surplus is Mg;
(2) manufacturing step of fascia board girder:
A. the casting of fascia board girder:
Lost foam casting is utilized to complete casting to fascia board girder;
B. the fine limit work of fascia board girder:
The fine limit works such as burring are carried out to the fascia board girder after casting.
Preferably, in described step (1), the percent by weight of fascia board girder is: Al:8.5%, Mn:0.4%, Zn:0.25%, Zr:0.6%, and surplus is Mg.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention is by changing the composition of magnesium alloy, makes the density of material low, stiffness-to-density ratio and strength-to-density ratio high, thus reach the object of the Combination property improving material.
(2) the inventive method is simple, and cost is low, handling ease.
