Abstract

The utility model discloses a light-duty rim shaped steel, including at least one section steel sheet that is used for making the rim, two faces of steel sheet on be equipped with a plurality of arc archs respectively, arc arch on two faces is symmetrical structure along the longitudinal center of steel sheet. In the scheme, a plurality of arc-shaped bulges are respectively rolled on two surfaces of a steel plate for manufacturing the rim section steel, the arc-shaped bulges respectively correspond to stress parts on the rim section steel, and the bulges play a role of reinforcing ribs on the tubeless rim. Because the arc-shaped bulges are of a symmetrical structure along the longitudinal center plane of the steel plate, and the two sides of the stressed part of the steel plate are thickened, the rim made of the steel plate roll-formed section with the same material thickness is high in strength, the material thickness of the section required when the rim with the same strength is manufactured is reduced, and the rim manufacturing cost is saved.

Description

light rim profile

technical field

The utility model relates to a light rim steel used for making wheels. the

Background technique

The rim is the part of the wheel that is assembled with the tire to support the tire. It includes the rim, the bead seat and the bottom of the groove. It is usually formed by rolling a piece of flat steel. In the rolling process, the thickness of all the bending parts and stress points are equal, so the bending parts and stress points will be stretched and thinned during the extrusion process, and it is easy to cause cracking (commonly known as " "Blowing up the edge") and other damages will lead to catastrophic consequences for the driving vehicle. Therefore, in order to increase the strength of the rim, thicker steel plates are often used for roll forming, which is costly, heavy, and wastes resources. the

Utility model content

The purpose of the utility model is to provide a light-duty rim steel for making wheels to solve the problems of high cost and heavy weight of existing rims. the

In order to achieve the above purpose, the solution adopted by the utility model is: light-duty rim steel, including at least one section of steel plate used to make the rim, the two surfaces of the steel plate are respectively provided with a number of arc-shaped protrusions, and the two surfaces The arc-shaped protrusions have a symmetrical structure along the longitudinal center plane of the steel plate. the

The arc-shaped protrusions are respectively arranged at both ends of the rim of the rim, at the connection between the bead seat of the rim and the rim of the rim, and at the arc of the bottom of the groove. the

The light rim section steel includes 2-5 segments of steel plates for making rims, and the light rim section steel is made by rolling a whole piece of steel plate. the

There is thickening on the steel plate corresponding to the wheel rim and the arc-shaped protrusion. the

In this scheme, several arc-shaped protrusions are respectively rolled on the two surfaces of the steel plate for making the rim-shaped steel, and the arc-shaped protrusions respectively correspond to the stressed parts on the rim-shaped steel. Play the role of reinforcement. Since the arc-shaped protrusions have a symmetrical structure along the longitudinal center plane of the steel plate, and are thickened on both sides of the steel plate at the stressed part, the strength High, when making a rim with the same strength, the material thickness of the profile is reduced, which saves the manufacturing cost of the rim. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail. the

As shown in Figure 1, the light-duty rim profile steel 5 of the present utility model includes at least one section of steel plate for making the rim. The arc-shaped protrusions on one surface have a symmetrical structure along the longitudinal center plane of the steel plate. the

As shown in Figure 2, the light-duty rim section steel 5 of the present utility model is compared with the cross-sectional view of the rim rolled by it. One surface of the steel plate at the joint between the bead seat 3 and the rim flange 1, and the groove bottom arc 2, thus forming concavo-convex ribs spaced apart on one surface of the profile steel plate. The light-duty rim section steel is made by rolling a whole piece of steel plate. A piece of light-duty rim section steel can include 1 section, 2 sections, 3 sections, 4 sections or 5 sections, etc. for making the steel plate 5 of the rim. The section steel is made by rolling a whole piece of steel plate . In order to improve the strength of the rolled rim, the thickness of the steel plate can be increased at the rim 1 and the arc-shaped protrusion. the

The thickness of the wheel rim made of the wheel rim steel profile of the utility model is increased at the wheel rim, the bead seat rounded corners, the rounded corners at the joint between the bead seat and the groove bottom 4, and the stressed bending parts. At the same time, the thickness of the non-stressed surface is reduced. In particular, arc-shaped protrusions are set on both sides of the steel plate of the light-duty rim section steel, so that the total weight is reduced when the strength is increased, and for the rim made of the rim section bar pressed by flat steel, the The strength is increased, the service life of the product is extended, and the cost is reduced. At the same time, because the rim is light, the wheel made of it is also light, which can save the fuel consumption of the vehicle when driving. the
