Description
Technical field
The present invention relates to automobile axle housing part manufacturing field, a kind of particularly technique side for manufacturing automobile axle housing part
Method.
Background technique
The conventional fabrication processes of automobile axle housing, generally by the way of monoblock cast or difference punching press again weld assembly.It is whole
The shortcomings that body casting method is that pts wt is larger, is unfavorable for loss of weight and reduces oil consumption；Respectively punching press again weld assembly the shortcomings that
It is that weld seam is more, deflection is larger, and welding defect is difficult to avoid that.It is welded again after also useful monolith steel plate cold stamping forming at present
Method, in the fabrication process, part deformation rebound are not easy to adjust, and entrucking is cracked using rear commissure fatiguability, lead to oil leak etc.
Failure.Axle housing can also use the integrally formed technique of filling liquid, but existing liquid-filling shaping scheme complex procedures, bulging rate be difficult be more than
200%, be not suitable for the axle housing part of the larger bulging amount of manufacture.
Rear axle housing will not only protect the parts such as internal retarder and differential mechanism as one of most important components of automobile
Assembly, still suffers from car body weight and wheel rotates the torque transmitted, it is therefore desirable to have enough strength and stiffness.
Disadvantage existing in the prior art:
1, often, processing cost is excessively high for part forming, and production efficiency reduces；
2, deflection used in normal fluid pressure formation of parts bulging region both is from the supply at pipe both ends, so if needing
Wanting aximal deformation value, then required pipe length is longer；
3, pressure-loaded path and feed supplement are flux matched unreasonable, easily wrinkle, forming defects, pipe and the mold such as cracking
Frictional force existing for surface can only thicken port pipe wall thickness if only leaning on both ends feed supplement, be difficult pipe feed supplement to rising
Shape region, so as to cause pipe rupture.
Based under background above technology, it is proposed that a kind of process for manufacturing automobile axle housing part.
Summary of the invention
To solve the deficiency mentioned in above-mentioned background technique, the purpose of the present invention is to provide a kind of manufacture automobile axle housings zero
The process of part, the present invention manufacture axle housing using pipe as raw material, using the method for novel liquid-filling shaping, and bulging amount reaches
300% or more, far beyond conventional deformation amount, axle housing is improved stock utilization, is reduced part weight using integrally formed
Amount；
Manufacturing procedure is decreased in processing, reduces mold manufacture and production cost, since there is no welderings after forming
Process is connect, the failures such as the oil leak as caused by weld cracking can be fundamentally solved.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of process manufacturing automobile axle housing part, the manufacturing equipment of the process includes lower die holder and setting
The upper die holder held on the lower die seat, lower die holder upper end two sides are respectively equipped with loose plug and lower die right side activity edge on the left of lower die
Block.
Upper die holder bottom end two sides are respectively equipped with loose plug and upper mold right side loose plug, upper mold left side on the left of upper mold
Moisturizing sealing push top is equipped on the left of loose plug and lower die between loose plug, is provided with fill hole in moisturizing sealing push top.
Sealing push top is equipped between loose plug and lower die right side loose plug on the right side of the upper mold.
The process the following steps are included:
One, pipe is placed on to the upper end of lower die holder, loose plug, upper mold right side loose plug and upper die holder on the left of upper mold
It moves downward, until stop motion after upper die holder and pipe contact, realizes the molding of upper die holder and lower die holder；
Two, after the completion of molding, by moisturizing seal on the left of push top insertion upper mold on the left of loose plug and lower die loose plug it
Between, sealing is had a haircut between insertion upper mold right side loose plug and lower die right side loose plug, to the pipe of pipe two sides after insertion
It mouthful is blocked, it is to be confirmed close until then water filling fills water in by pipe out of fill hole in moisturizing sealing push top
It is honored as a queen, from fill hole to pressurizeing in pipe, is gradually pressurized to low-pressure state；
Three, in a low voltage state, drive loose plug on the left of lower die, lower die right side loose plug, upper mold left by oil cylinder
Loose plug moves inwardly simultaneously on the right side of side loose plug and upper mold, until loose plug, the activity of lower die right side on the left of lower die
Loose plug, upper mold right side loose plug and lower die holder, the fitting of upper die holder side on the left of insert, upper mold；
Four, to activity on the right side of loose plug, lower die right side loose plug, upper mold left side loose plug and upper mold on the left of lower die
After insert movement in place, the flat form that continues growing overpressure to required forming pressure, to pipe bulging to mold；
Five, after bulging, overpressure is reduced to 2-5Mpa, moisturizing sealing push top and sealing push top is driven to make it outward
Side retracts, meanwhile, activity on the right side of loose plug, lower die right side loose plug, upper mold left side loose plug and upper mold on the left of lower die
Insert is retracted together to initial state；
Six, upper die holder is opened, mold is taken out.
Further, loose plug and lower die right side loose plug seal and are slidably arranged in lower die holder on the left of the lower die
Both ends.
Further, loose plug and upper mold right side loose plug seal and are slidably arranged in upper die holder on the left of the upper mold
Both ends.
Further, the mode of sealing is confirmed in the step 2 are as follows: first detect overpressure energy under 2-5Mpa pressure
No holding 2-5s, be able to maintain illustrate to seal it is intact, if pressure declines always, illustrate sealing be not acted upon, will sealing push top
It is i.e. salable to continue movement inside with sealing push top.
Further, the low pressure pressure in the step 2 is 10-20Mpa.
Further, the driving force of the oil cylinder in the step 3 need to be greater than 2.94*10^6N, and the speed at the uniform velocity driven is
20-30mm/s。
Further, the position being bonded in the step 3 is controlled by the displacement sensor on oil cylinder, passes through displacement sensing
The mobile distance of device feedback and then command displacement distance.
Further, required forming pressure is 250Mpa in the step 4, so that pipe overflow mold.
Beneficial effects of the present invention:
1, the present invention using pipe as raw material, using novel liquid-filling shaping method manufacture axle housing, bulging amount reach 300% with
On, far beyond conventional deformation amount, while eliminating the influence of rebound to guarantee the accurate of part shape, axle housing using one at
Shape improves stock utilization, reduces pts wt；
Manufacturing procedure is decreased in processing, reduces mold manufacture and production cost, since there is no welderings after forming
Process is connect, the failures such as the oil leak as caused by weld cracking can be fundamentally solved；
2, during hydroforming feed supplement, axial feature is gradually reduced the present invention, and normal direction feature is gradually increased, it is ensured that
Always in progressive deformation in deformation process, large deformation is accumulated by small deformation, blank can be effectively reduced during feed supplement
Because feed supplement it is too fast caused by corrugation, unstability, cracking the defects of；
3, the present invention is using preform to flat form, due to reducing part forming step, effectively controls product and is thinned
Rate reduces production cost.
