Earthmoving machine wheel lock ring machining technology

Abstract

The invention provides an earthmoving machine wheel lock ring machining technology. Lock ring structural steel rolling, edge rolling, cutting-off, spot welding, heating, pressing forming, prizing portmilling and welding spot and burr removing are included. Round steel is adopted as a raw material for rolling of lock ring structural steel, the lock ring structural steel is subjected to online edgerolling, a blank obtained after edge rolling is cut off, and the blank obtained after cutting-off is obtained; the cut-off blank is subjected to closing-up and spot welding, the blank obtained afterspot welding is subjected to heating treatment, the heated blank is pressed and pressed into the preset shape, the formed blank is subjected to prizing port milling, welding spots and burrs on the blank obtained after prizing port milling are removed, and a lock ring is obtained. The round steel is adopted as the raw material in the lock ring machining technology, the lock ring structural steel raw material machining procedures are reduced, and the production cost is reduced; the lock ring structural steel is subjected to online edge rolling, cutting heads are reduced, and the material utilization rate is high; and heating is conducted after spot welding, pressing forming is conducted after heating, the formed blank is obtained, the forming effect is good, and size stability is good.

Description

technical field [0001] The invention relates to the field of earth-moving machinery wheels, in particular to a processing technology for earth-moving machinery wheel lock rings. Background technique [0002] At present, earth moving machinery refers to machinery for excavating, shoveling, pushing or leveling soil and gravel. Such as bulldozers, scrapers, excavators, loaders, graders, earth moving machines and dump trucks, etc., are widely used in construction, water conservancy construction, road construction, airport construction, mining, wharf construction, farmland improvement and other projects . Due to the complex working environment of earth-moving machinery vehicles, the safety performance requirements of the wheels are relatively high. The lock ring is a key safety component of the wheel, and the lock ring is an indispensable wheel accessory that locks the wheel rim (or retaining ring) on ​​the rim. The lock ring is an open structure, and the lock ring is set in t...
