Non-welding unequal-thickness wheel of wheel type construction mechanical vehicle and machining process thereof

Abstract

A non-welding unequal-thickness wheel of a wheel type construction mechanical vehicle comprises a rim, a bead seat and a spoke. The rim and the bead seat are integrally formed through spinning, and the bead seat and the spoke are integrally formed through forging and pressing. The wheel is finally formed after multiple procedures with spinning as the main procedure, automatic production can be conveniently achieved, and machining precision is high. The spoke and the rim are formed through spinning of one blank material and are free of any assembling joint face, welding line and solder filler, the structure is fine, and the strength is improved. A welding link is omitted in the machining process of the wheel, the difficult welding problem of high-strength steel can be solved, and the defects in hot rolling, welding and grinding are overcome; meanwhile, the welding link is omitted, so that sparks, dust and other pollutions caused by welding are eliminated; and the problem that rim weld positions and spoke weld positions are prone to cracking is solved, and potential traffic safety hazards are greatly reduced.

Description

technical field [0001] The invention relates to the field of construction machinery wheels, in particular to a non-welded and unequal-thickness wheel construction machinery wheel and its processing technology.

AI Technical Summary

Problems solved by technology

[0002] There are many limitations in the production process and product itself of traditional wheeled construction machinery wheels. The spokes and rims of this kind of wheels come from two different raw materials, and After clamping, positioning and other process routes, they are manufactured separately, and finally assembled and welded. The manufacturing production is divided into three production lines: spoke, rim and assembly. The process is cumbersome, the management is complicated, and the production environment involving welding is relatively harsh. During the production process Existence of sparks, dust, etc.

In addition, there are defects in the hot rolling, welding and grinding of the rim, and there are difficulties in the welding of the assembly. After many times of assembly and welding, the product cannot achieve higher precision

During the driving process, when the wheel is stressed, it is easy to break from the welding seam position of the rim and the welding seam of the spoke rim, which can easily cause traffic safety hazards
