Problems solved by technology

Although the above-mentioned patents all involve the production process of the spokes, they have not covered the technical characteristics of the spokes used in engineering vehicles, and the control precision of the production process is low, resulting in unstable quality control of the spokes and insufficient installation dimensions.
[0005] In fact, the spokes of the existing engineering wheel rims, especially the spokes on large and medium-sized engineering vehicles, still have defects such as low strength, heavy weight, and large material loss, which have a lot to do with their processing technology, such as insufficient strength. During the punching process, the arc-shaped processed surface is prone to micro-cracks under external force stamping. Micro-cracks will cause the spokes to expand and break under high loads, which will affect the service life of the wheels and even cause unnecessary safety accidents.

Abstract

The invention belongs to the technical field of spokes of engineering machinery, and aims to provide a production process of spokes for engineering machinery wheels. The production process specifically comprises twelve procedures of blanking, forming, punching, air hole punching, extruding and chamfering, air hole reaming, air valve hole punching, flattening, machining, drilling, counter sinking, steel seal stamping and the like. The unique extruding and chamfering procedures are adopted, the problem of micro cracks generated by air hole punching is effectively solved, and the machining efficiency and the installation performance of bolt holes are improved through the counter sinking technology. The prepared spokes of the engineering machinery wheels have the advantages of being high in strength, free of micro cracks, accurate in size, small in installation error, stable in physical and chemical performance, high in yield (larger than or equal to 99.5%) and the like, and can be widely applied to the field of engineering machinery wheels.

Description

technical field [0001] The invention relates to the technical field of engineering wheel spokes, in particular to a production process for engineering machinery wheel spokes. Background technique [0002] Construction machinery vehicles are important equipment for national infrastructure construction. With the country's extensive and in-depth industrial upgrading, users have higher and higher requirements for construction machinery vehicles. Therefore, the requirements for construction machinery wheels are also constantly improving, especially Large or super-large construction machinery vehicles have very strict requirements on mechanical properties. [0003] At present, the wheel rims used in existing engineering vehicles are basically composed of rims, spokes, lock rings and outer rims. The role of the installation connection. Its structure is mostly a circular cover plate. The diameter of the cover plate is close to the diameter of the rim. There is a hole in the center...
