Embodiment Construction

[0007] The steel ring hot-rolled section steel for the excavator wheel of the present invention is realized in this way, which will be described in detail below in conjunction with the accompanying drawings. As shown in Figure 1, the hot-rolled section steel at the upper end of the hot-rolled section steel for the steel ring of the excavator wheel is in the shape of a spoon as a whole, and the spoon part is in the shape of a groove. ° included angle, the bottom of the spoon body has an included angle of α=30° with the horizontal direction, and there are 45° chamfers on the upper and lower sides of the end of the spoon body; It is made by hot-rolling, with 45° chamfers on the upper and lower sides of both ends; With a chamfer of 45°, the upper and lower sides of the other end are rounded, and the arc R=12mm.

Abstract

The invention relates to a steel ring hot-rolled section steel for excavator wheels, characterized in that: an upper hot-rolled section steel is a spoon body on the whole with a spoon part thereof in the shape of a groove, an included angle with alpha equal to 120 degrees is formed between the horizontal direction and the junction of the bottom of the groove and the spoon body, an included angle with alpha equal to 30 degrees is formed between the horizontal direction and the bottom of the spoon body, 45-degree chamfer angles are respectively formed at two faces, upper and lower, of the end of the spoon body; an intermediate hot-rolled section steel is a straight steel formed by hot-rolling, with 45-degree chamfer angles being respectively formed at upper and lower faces of two ends thereof; a lower hot-rolled section steel is also a straight steel formed by hot-rolling, with 45-degree chamfer angles being respectively formed at upper and lower faces of one end thereof and circular arc chamfer angles being respectively formed at upper and lower faces of the other end thereof, wherein the circular arc R is equal to 12mm. The steel ring hot-rolled section steel simplifies the technology for manufacturing wheels of large heavy-duty excavator, is liable to batch production, and achieves the effect of small loss of materials, short processing period and greatly reduced production cost.

Description

technical field [0001] The invention belongs to metallurgical hot-rolled section steel, in particular to a steel ring hot-rolled section steel used for wheels of large load excavators. Background technique [0002] At present, steel rings for construction machinery in my country, such as large-scale load-bearing excavator wheels, are manufactured by welding the middle plate in sections after machining. , The cost is high, the demand for production equipment is large, and it is not easy to form a production scale, which affects the benefits of the enterprise. Contents of the invention [0003] The present invention overcomes the above existing defects, and aims to provide a hot-rolled section steel for the steel ring of the excavator wheel for the steel ring of the large load excavator wheel. [0004] Brief description of the content of the hot-rolled section steel for the steel ring of the excavator wheel of the present invention: [0005] The hot-rolled section steel for...
