Abstract
The invention discloses a rim deformed steel section. The section comprises at least a segment of steel plate used for producing a rim, one surface of the steel plate is flat, and the other surface is provided with a plurality of certain arc protrusions. The arc protrusions are respectively arranged on both ends of a flange of the rim, the connection portion of a bead seat of the rim and the flange of the rim, and an arc portion at the bottom of a groove. According to the technical scheme of the rim deformed steel section, a plurality of certain arc protrusions are arranged on the plate used for producing the rim deformed steel, and every arc protrusion respectively corresponds to a force carrying portion on the rim steel and serves as a stiffener on the tubeless rim. Compared with rims produced by sections of the same thickness and roll forming, the rim deformed steel section is high in strength, so that the thickness of the sections for producing the rim of the same strength is reduced to save rim manufacturing cost.
Description
Technical field
The present invention relates to a kind of special-shaped steel profile for rims for making wheel.
Background technology
Wheel rim is the wheel part that cooperates support tire with tire, and it comprises the parts such as wheel rim, bead seat and bottom land, is normally formed by roll extrusion by the one flat plate steel.In rolling process, all crooked positions and the thickness of stress point all equate, so sweep and stress point can stretch and attenuation in the process of extruding, easily cause the infringement such as cracking (being commonly called as " fried large limit ") when heavier stressed, catastrophic consequence occurs in the vehicle in causing travelling, therefore in order to increase the intensity of wheel rim, the thicker steel plate flow forming of normal employing, cost is high, weight is large, the wasting of resources.
Summary of the invention
The object of the present invention is to provide low, the high-intensity special-shaped steel profile for rims of a kind of cost.
For achieving the above object, special-shaped steel profile for rims of the present invention comprises at least one section steel plate that is used for making wheel rim on this section bar, and the one side of described steel plate is the plane, and another side is provided with some arc convex.
Further, described arc convex is separately positioned on wheel rim two ends, wheel rim bead seat and rim junction, the bottom land circular arc place of wheel rim.
Further, comprise on the described section bar that the 2-5 section is used for making the steel plate of wheel rim, described section bar is made by the roll extrusion of monoblock steel plate.
Further, be provided with thickening corresponding to wheel rim and described arc convex place on the described steel plate.
In this programme, rolling on the steel plate of rim shaped steel some arc convex are arranged making, this arc convex corresponds respectively to part of the force on the rim shaped steel, this projection plays reinforced rib at tubeless rim, for identical material thick the wheel rim made of the section bar of steel plate flow forming, its intensity is high, needs thick reduction of material of section bar when making the wheel rim of same intensity, has saved the wheel rim manufacturing cost.

Among the figure, 1, wheel rim, 2, the bottom land circular arc, 3, bead seat, 4, bottom land, 5 deformed steel section bars, 6, wheel rim.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described in detail.
As shown in Figure 1, special-shaped steel profile for rims of the present invention, it comprises at least one section steel plate 5 that is used for making wheel rim, and the one side of this steel plate is the plane, and another side is provided with some arc convex.
As shown in Figure 2, deformed steel section bar of the present invention 5 and cross-sectional plane contrast scheme drawing by its rolling wheel rim that forms 6.On the two ends, wheel rim bead seat 3 that described arc convex is arranged at respectively the wheel rim 1 of corresponding wheel rim and the face of the steel plate at rim 1 connecting portion, bottom land circular arc place 2, formed concavo-convex reinforced rib separately on a surface of section bar steel plate like this.
Can comprise on section bar that the multistages such as 1 section, 2 sections, 3 sections, 4 sections or 5 sections are used for making the steel plate 5 of wheel rim, section bar is made by the roll extrusion of monoblock steel plate.In order to improve the intensity of rolling wheel rim, can be at the thickness of wheel rim 1 and arc convex part increase steel plate.
The thickness of the force parts such as with the wheel rim that wheel rim of the present invention opposite sex steel profile is made, it is at wheel rim, bead seat fillet, the fillet of bead seat and bottom land connecting portion and stressed sweep has obtained increase, simultaneously, has reduced the thickness of non-stress face.Like this so that in the situation of gaining in strength total weight by descend, the wheel rim of making for the wheel rim section bar of flat plate steel compacting, improved intensity, prolonged product service life, reduced cost, because wheel rim is light, its wheel of making is also light, can save vehicle oil consumption in motion simultaneously.
Claims (4)
