Wheel, rim rotary rolling process and rotary rolling device

Abstract

The invention aims to provide a wheel, a rim rotary rolling process and a rotary rolling device. The wheel comprises a rim and a spoke, wherein the rim comprises an outer tire ring seat, a first rotary rolling section, a bottom groove, a second rotary rolling section and an inner wheel edge which are successively connected; the second rotary rolling section is provided with an inner tire ring seatconnected to the inner wheel edge; the first rotary rolling section and the second rotary rolling section are separately thinner than the outer tire ring seat, the bottom groove and the inner wheel edge; transitional circular beads which are gradually thinned are arranged at the connecting end of the outer tire ring seat, the connecting end of the bottom groove and the first rotary rolling section, the connecting end of the bottom groove and the second rotary rolling section and the connecting end of the inner wheel edge and the inner tire ring seat; the spoke is connected to the outer end ofthe outer tire ring seat; and the spoke is provided with an outer wheel edge. Thicknesses of all parts of the rim of the wheel correspond to the stress, so that the wheel is relatively light in weight; and the outer wheel edge is arranged on the spoke and the rim is connected to the outer end of the outer tire bead ring, so that the rim can meet the strength demand with relatively small thickness, so that the weight of the wheel is alleviated.

Description

technical field [0001] The invention relates to the field of wheel manufacturing, in particular to a wheel and rim spinning and rolling process and a spinning device. Background technique [0002] Steel wheels are low in cost and good in safety, and have long been dominant in automobile wheels, especially steel wheels are used for most of the wheels of trucks; the rim of the wheel is the carrier of the tire, and its various properties have a great impact on the tire and the car. Normal use has an important impact; the invention of Chinese patent application number CN201310229679.7 discloses an automobile wheel rim and its spinning process, including an outer bead seat, an inner bead seat, and a bottom between the inner bead seat and the outer bead seat The groove, the outer rim connected to the end of the outer bead seat, the inner rim connected to the end of the inner bead seat, the outer bead seat and the inner bead seat are respectively provided with an outer spinning are...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the current wheels that meet the overall strength through thicker rim thickness. The traditional spinning process has the disadvantages that the thickness of the rim is thicker and the weight is heavier, and the hardness of the rim material and the structural strength are low. Provide The thickness of the produced rim corresponds to the magnitude of the force at each position of the rim, the wheel is light in weight, and the hardness of the rim material and the structural strength are high, the rim spinning and rolling process and the spinning device
