The method comprises the following manufacturing steps: (1) performing solution treatment on the automotive instrument panel beam; and (2) performing aging treatment on the automotive instrument panel beam. According to the method disclosed by the invention, the problem the mechanical property needs to be further optimized in the process of manufacturing the conventional automotive instrument panel beam by utilizing a magnesium alloy is solved, and the heat treatment method has the advantages of simple method, low cost and simplicity in processing.
Description
Technical field
The invention belongs to non-ferrous metal field, more particularly, relate to a kind of heat treating method of fascia 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 vehicles, weaving and printing because low density, specific rigidity and specific tenacity 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 automobile component and usually has the following advantages: (1) improves fuel economy comprehensive standard, reduce exhaust gas 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 stowage capacity and useful load that can increase vehicle, can also improve brake and acceleration characteristics simultaneously; (3) noise and vibration of vehicle can greatly be improved.
Fascia board girder is the bearing carrier supporting man-machine interface in automobile, and forms security system together with other safety members, and can play the effect of officer 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, higher requirement is proposed to choosing of material, need the characteristic that low density, specific rigidity and specific tenacity are high, magnesium alloy then can meet this demand well, but general magnesium alloy also needs to be optimized its mechanical property in the fabrication process.
Summary of the invention
Utilizing in magnesium alloy manufacturing processed for existing fascia board girder, the problem that its mechanical property needs to be optimized, the invention provides a kind of heat treating method of fascia board girder, by changing the heat treatment mode in fascia board girder manufacturing processed, alloy is strengthened, thus reaches the object improving its mechanical property.
For solving the problem, the present invention adopts following technical scheme.
A heat treating method for fascia board girder, comprises the following steps:
(1) solution treatment of fascia board girder:
A. fascia board girder is heated to 370-390 DEG C, insulation 2
h;
B. fascia board girder is heated to 410-430 DEG C, insulation 14-20
h, then air cooling;
(2) ageing treatment of fascia board girder:
Fascia board girder is heated to 170-180 DEG C, insulation 16-18
hrear air cooling.
Preferably, in described step (2), fascia board girder is heated to 175 DEG C, insulation 17
hrear air cooling.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention is by changing the heat treatment mode in fascia board girder manufacturing processed, and alloy is strengthened, and its mechanical property is improved.
(2) the inventive method is simple, and cost is low, handling ease.
