Description
Technical field
The utility model relates to technical field of automobile accessories, specially a kind of hydro-forming fore sub frame.
Background technique
Fore sub frame is the important component of vehicular chassis system, mainly includes fore sub frame main body, and with vehicle body, outstanding
Set and the parts such as suspension connection connection structure.Fore sub frame can also obstruct vibration and make an uproar other than supporting the above part
Sound reduces it and is directly entered compartment, so being appeared on luxurious car and offroad vehicle mostly, some automobiles are also loaded onto for engine
Subframe.Traditional fore sub frame is all made of punch welding technique and is made, and not only shape, precision are low, and mold, material cost are high, weight
Greatly, and subsequent mechanical processing and assembly welding amount are big, and defect is obvious.For this purpose, it is proposed that a kind of hydro-forming fore sub frame.
Utility model content
The purpose of this utility model is to provide a kind of hydro-forming fore sub frames, to solve to propose in above-mentioned background technique
Traditional fore sub frame be all made of punch welding technique and be made, not only shape, precision are low, and mold, material cost are high, and weight is big,
And subsequent mechanical processing and assembly welding amount are big, the obvious problem of defect.
To achieve the above object, the utility model provides the following technical solutions: a kind of hydro-forming fore sub frame, including by
The fore sub frame that front-axle beam, the back rest, You Liang and left beam form, the front-axle beam are process using hydro-forming method, the front-axle beam
Both ends are provided with arc fold bending portion, and one end difference arc-welding of the You Liang and left beam is described in the end in two arc fold bending portions
It is provided with back bush on the right side of the upper surface of right side of the back rest arc-welding between You Liang and left beam, the You Liang and left beam, it is described
The equal arc-welding in left side both ends of front-axle beam has installation tower seat, and front lining is provided on the installation tower seat, and the front surface of the right beam is right
Arc-welding has reinforced support on the right side of side and the right surface of left beam.
Preferably, the front-axle beam is the Guan Liang that inside is hollow structure.
Preferably, two installation tower seats are located in two arc fold bending portions of front-axle beam.
Preferably, the You Liang and Zuo Liang is all made of metal plate and lower metal plate welding forms.
Compared with prior art, the utility model has the beneficial effects that before a kind of hydro-forming that the utility model proposes
Subframe uses fluid as medium using hydroforming process, the complicated knot that this rigid die of front beam can not be shaped
Structure processes；For hydroforming process is compared with conventional ones welding procedure, product weight can be mitigated significantly, save material and liquid
Molding die usually only needs 1 set, and stamping parts needs multiple sets of molds mostly, therefore can be reduced part and die cost and life
The period is produced, the hydro-forming part secondly obtained under internal superhigh pressure liquid and the collective effect of both ends axial thrust feed supplement is opposite
Punch welding part shape and precision all greatly improve.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 front-axle beam, 2 back rest, 3 right beams, 4 left beams, 5 installation tower seats, 6 front linings, 7 back bushes, 8 reinforced supports.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of hydro-forming fore sub frame, including by front-axle beam
1, the fore sub frame that the back rest 2, right beam 3 and left beam 4 form, the front-axle beam 1 are process using hydro-forming method, the front-axle beam 2
Both ends be provided with arc fold bending portion, one end difference arc-welding of the right beam 3 and left beam 4 in the end in two arc fold bending portions,
After being provided on the right side of the upper surface of right side of 2 arc-welding of the back rest between right beam 3 and left beam 4, the right beam 3 and left beam 4
Bushing 7, the equal arc-welding in left side both ends of the front-axle beam 1 has installation tower seat 5, is provided with front lining 6 on the installation tower seat 5, described
On the right side of the front surface of right beam 3 and the arc-welding of the right surface of left beam 4 right side has reinforced support 8.
Wherein, the front-axle beam 1 is the Guan Liang that inside is hollow structure, and two installation tower seats 5 are located at front-axle beam 1
In two arc fold bending portions, the right beam 3 and left beam 4 is all made of metal plate and lower metal plate welding forms.
Working principle: front-axle beam 1 is the Guan Liang that inside is hollow structure, is processed using cross-section design and hydroforming process
It forms, then front-axle beam 1, the back rest 2, right beam 3 and left beam 4 is linked together using arc welding process, then 5 He of tower seat will be installed again
Reinforced support 8 distinguishes arc-welding on front-axle beam 1, right beam 3 and left beam 4, and front lining 6 and back bush 7 are finally distinguished interference press fitting again
On installation tower seat 5, right beam 3 and left beam 4, which uses fluid as Jie using hydroforming process
Matter processes the labyrinth that this rigid die of front beam can not shape；Hydroforming process is welded compared with conventional ones
For technique, product weight can be mitigated significantly, material is saved and hydroforming die usually only needs 1 set, and stamping parts is most
Multiple sets of molds are needed, therefore can be reduced part and die cost and production cycle, secondly in internal superhigh pressure liquid and two end axles
The hydro-forming part obtained under to the collective effect of thrust feed supplement is all greatly improved with respect to punch welding part shape and precision.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
