Description
Technical field
The present invention 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.
Summary of the invention
The purpose of the present invention is to provide a kind of hydro-forming fore sub frames, to solve biography mentioned above in the background art
System 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, 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 invention provides the following technical scheme: a kind of hydro-forming fore sub frame, including by preceding
The fore sub frame that beam, the back rest, You Liang and left beam form, the front-axle beam are process using hydro-forming method, and the two of the front-axle beam
End is provided with arc fold bending portion, and one end difference arc-welding of the You Liang and left beam is in the end in two arc fold bending portions, after described
It is provided with back bush on the right side of the upper surface of right side of the beam arc-welding between You Liang and left beam, the You Liang and left beam, before described
The equal arc-welding in left side both ends of beam has installation tower seat, and front lining, the front surface right side of the right beam are provided on the installation tower seat
There is reinforced support with arc-welding on the right side of 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 beneficial effects of the present invention are: a kind of hydro-forming fore sub frame that the invention proposes, is adopted
With hydroforming process, medium is used fluid as, the labyrinth that this rigid die of front beam can not shape is processed
Come；For hydroforming process is compared with conventional ones welding procedure, product weight can be mitigated significantly, save material and hydro-forming mould
Tool usually only needs 1 set, and stamping parts needs multiple sets of molds mostly, therefore can be reduced part and die cost and production cycle,
Secondly the hydro-forming part obtained under internal superhigh pressure liquid and the collective effect of both ends axial thrust feed supplement is welded with respect to punching press
Fitting shape and precision all greatly improve.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
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
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of hydro-forming fore sub frame, including by front-axle beam 1, after
The fore sub frame that beam 2, right beam 3 and left beam 4 form, the front-axle beam 1 are process using hydro-forming method, and the two of the front-axle beam 2
End is provided with arc fold bending portion, and one end difference arc-welding of the right beam 3 and left beam 4 is described in the end in two arc fold bending portions
Back bush is 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
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, the right beam 3 on the installation tower seat 5
Front surface on the right side of and left beam 4 right surface on the right side of arc-welding have 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.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
