Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a wheel spoke structure design and processing method, to solve the problem that the existing wheel ultra-wide spoke adopts the lower round cake material, adopts cutting or punching, and the material utilization rate falls within 45%~ Between 65%, resulting in a huge waste of materials

Embodiment Construction

[0017] The ultra-wide spoke is designed as a structural part composed of two or more ring materials welded from a single piece of material, that is, two or more strips are cold-processed into ring materials, and then assembled and welded. The round cake material is reshaped and then assembled on the rim to form the wheel.

[0018] The specific width size, geometry, bolt hole distribution circle diameter and bolt hole diameter of the super-wide spoke are the basis for designing whether there are two or more ring welds, and the number of ring materials is obtained; in short, a single circle The ring material width should be less than 130. The position of the ring weld must avoid the inflection point of the geometry, as well as the positions of the bolt holes and air holes.

[0019] The number of longitudinal welds is determined by the ring material, and there are as many longitudinal welds as there are ring materials; the position of the longitudinal welds must avoid bolt holes,...

Abstract

The invention discloses a design and a process of mechanical parts, and particularly relates to a process for designing and processing a wheel spoke structure on various wheels. The process for designing and processing the wheel spoke structure comprises the steps of carrying out cold machining on two or more strips into a circular ring, installing and welding the circular ring into a cake material, forming, assembling the cake material on a rim, and welding into a wheel. The process has the characteristic that at least one ring weld and more than two longitudinal welds are arranged on the wheel spoke, and the wheel spoke structure can be seen in attached drawings. The process has the advantages that the material utilization rate is increased to about 95 percent from below 65 percent in comparison with that of a process for directly producing a cake material by a super-wide wheel spoke; a cold machining process is always adopted, an incircle does not wrinkle up, and the heat consumption is not increased, thus the process is very environmental-friendly.

Description

technical field [0001] The invention relates to a design and technology of mechanical parts, in particular to the design and processing technology of spoke structures on various wheels. Background technique [0002] At present, whether it is rolled into a cylindrical material with flaring and flanging, and then pressed into a spoke blank, or rolled into a conical tube, pressed into a spoke blank, or rolled into a ring material and flattened into a spoke blank, the width of the spoke blank is There are process restrictions, not unlimited, the width of the spoke blank changes with its diameter, and changes with the thickness, and if it exceeds the process limit, it will wrinkle in the spoke blank; this is because It is determined by the shrinkage rate of the material; whether it is hot forming or cold forming, there are wrinkles in the inner circle, but the size of the wrinkles changes, and only when the amount increases to a certain amount will there be a qualitative change. ...
