Abstract
The invention relates to a one-time roller forming I-beam which comprises a pair of wing plates and a web. The web and the wing plates are of an integrally formed structure. The web is located between the two wing plates and of an I-shaped structure. A plurality of rivets are riveted to the web. The I-beam is formed at one time, is convenient to machine and manufacture and capable of eliminating internal stress; the rivets, rivet welding points and reinforcing ribs are additionally arranged on the web, so that weight is reduced, torsion resistance and bearing capacity are improved, and the one-time roller forming I-beam is firm and durable.
Description
[technical field]
The present invention relates to a kind of auto parts and components, be specifically related to an a kind of roller moulding H-girder, can serve as structural steel, belong to technical field of automobile parts.
[background technology]
At present, the lightweight level of China's transport vehicle is with to compare gap abroad larger.And due to environmental protection and energy-conservation needs, the increasing of overload remediation dynamics, and heavily all-round popularization and the enforcement of charge of note, overweight vehicle will be released market.The lightweight of automobile has become the trend of world car development, is a developing direction of international automobile Innovation project.
Automotive frame is the important component part of automobile, and the quality of its performance is directly connected to the quality of vehicle performance.The automotive frame of prior art mainly adopts welding processing to form, and its process engineering is loaded down with trivial details, and inside exists stress, easily distortion.
And along with the development tendency of automotive light weight technology, automotive frame material therefor certainly will reduce to some extent, therefore, when how to make automotive frame weight saving, twisting resistance and bearing capacity strengthen, and this is a pendulum technical barrier in the field of business.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved roller moulding H-girder that has, to overcome described defect of the prior art.
[summary of the invention]
For addressing the above problem, the object of the present invention is to provide that a kind of weight is light, twisting resistance and bearing capacity is strong and a roller moulding H-girder of convenient processing and manufacture.
For achieving the above object, the technical scheme that the present invention takes is: an a kind of roller moulding H-girder, and it comprises a pair of wing plate and a web; Wherein, described web and the wing plate structure that is formed in one, and web is between two wing plates and be I-shaped structure; On described web, riveted joint has some rivets or rivet welding point.
A roller moulding H-girder of the present invention is further set to: on described web, flow forming has some reinforced ribs.
A roller moulding H-girder of the present invention is also set to: in the two ends of each wing plate, be respectively equipped with a round end.
Compared with prior art, the present invention has following beneficial effect: H-girder of the present invention adopts one-shot forming, makes its convenient processing and manufacture, and can eliminate internal stress; By set up rivet, rivet welding point and reinforced rib on web, in weight saving, increase twisting resistance and bearing capacity, durable.
[accompanying drawing explanation].
Fig. 1 is the schematic diagram of roller moulding H-girder first embodiment of the present invention.
Fig. 2 is the schematic diagram of roller moulding H-girder second embodiment of the present invention.
[specific embodiment]
Refer to shown in Figure of description 1, it is the first embodiment of a roller moulding H-girder of the present invention, and it is comprised of several parts such as a pair of wing plate 1 and webs 2, its endless.
Wherein, described web 2 and wing plate 1 adopts stiffness steel plate one-body molded, and web 2 is between two wing plates 1 and be I-shaped structure.
On described web 2, further riveted joint has some rivets or rivet welding point 4, thereby facilitates the docking of this H-girder and miscellaneous part, and the structural strength that strengthens H-girder.
In the two ends of each wing plate 1, be respectively equipped with a round end 5, thereby make this H-girder smooth surface.
Refer to shown in Figure of description 2, it is the second embodiment of a roller moulding H-girder of the present invention, the difference of itself and the first embodiment is: on described web 2, flow forming has some reinforced ribs 3, thereby further strengthens the structural strength of this H-girder.
Automotive frame of the present invention adopts one-shot forming, makes its convenient processing and manufacture, and can eliminate internal stress; By set up reinforced rib 3 on web 2, in weight saving, increase twisting resistance and bearing capacity, durable.
Through test, in the situation that carrying is the same, this kind of automotive frame at least alleviates 20% in deadweight, can also overloading in the same situation of deadweight, and automotive dead weight often alleviates 10%, and the fuel oil of fuel-economizing 6% at least.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
Claims (3)
1. a roller moulding H-girder once, is characterized in that: comprise a pair of wing plate and a web; Wherein, described web and the wing plate structure that is formed in one, and web is between two wing plates and be I-shaped structure; On described web, riveted joint has some rivets or rivet welding point.
2. a roller moulding H-girder as claimed in claim 1, is characterized in that: in the two ends of each wing plate, be respectively equipped with a round end.
3. a roller moulding H-girder as claimed in claim 2, is characterized in that: on described web, flow forming has some reinforced ribs.
