Abstract

The utility model discloses a rim deformed steel section bar includes one section at least steel sheet that is used for making the rim on this section bar, the one side of steel sheet be the plane, be equipped with a plurality of arcs arch on the another side. The arc-shaped bulges are respectively arranged at the two ends of the rim, the joint of the rim bead seat and the rim and the arc part of the groove bottom. In the scheme, the plurality of arc-shaped bulges are rolled on the plate for manufacturing the rim section steel, the arc-shaped bulges respectively correspond to the stress parts on the rim section steel, the bulges play a role of reinforcing ribs on the tubeless rim, the strength of the rim made of the steel plate roll-formed section with the same material thickness is high, the material thickness of the section is required to be reduced when the rim with the same material thickness is manufactured, and the rim manufacturing cost is saved.

Description

Special-shaped steel profile for rims

Technical field

The utility model relates to a kind of special-shaped steel profile for rims for making wheel.

Background technology

Wheel rim is to coordinate the wheel part of 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.

The utility model content

The purpose of this utility model is to provide that a kind of cost is low, high-intensity special-shaped steel profile for rims.

For achieving the above object, special-shaped steel profile for rims of the present utility model 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 the wheel rim two ends, wheel rim bead seat of wheel rim and rim junction, bottom land circular arc place.

Further, comprise on 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 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 rim shaped steel, this projection plays reinforced rib on 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.

The specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.

As shown in Figure 1, special-shaped steel profile for rims of the present utility model, it comprises at least one section steel plate 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 utility model 5 and cross-sectional plane contrast schematic diagram by its rolling wheel rim that forms 6.On a face of the steel plate at 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 rim 1 connecting portion, bottom land circular arc 2 places, formed concavo-convex reinforced rib separately like this on a surface of section bar steel plate.

As shown in Figure 3, 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 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 utility model 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.Make like this in the situation that gain in strength total weight by descend, the wheel rim of making for the wheel rim section bar of flat plate steel compacting, improved intensity, extended 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
