Description

Technical Field

[0001] The utility model relates to a combined roller ring for producing aluminum alloy forging rings. Background Art

[0002] Aluminum alloy forged rings are annular parts made from aluminum alloy through a forging process. Due to their lightweight and high strength, they are widely used in the aerospace industry for aircraft engine components and fuselage structures. For example, key components such as aircraft wheels and engine turbine discs are often manufactured using aluminum alloy forged rings. In automotive manufacturing, aluminum alloy forged rings are used in components such as wheels and engine crankshafts, reducing vehicle weight and fuel consumption while improving performance and safety. Aluminum alloy forged rings also play a vital role in various mechanical devices, serving as transmission components and seals. First, in actual production, aluminum alloy forging rings may need to have various special shapes and structures in order to meet the needs of different application scenarios; for example, some forging rings may need to have curved contours, irregular surfaces or internal cavities, etc.; these complex shapes require precise control of the flow and deformation of the material during the forging process, otherwise defects such as incomplete filling, folding, cracks, etc. are likely to occur; secondly, ordinary rectangular forging rings have obvious disadvantages in machining; due to their relatively simple and regular shape, which is quite different from the shape of the final product, the machining amount is usually large; in the machining process, a large amount of material needs to be removed, which not only consumes a lot of time and energy, but also increases production costs, seriously restricting the subsequent machining use of the forging rings; and the production of special-shaped forging rings is very expensive and uneconomical because special rolling rollers need to be manufactured. Utility Model Content

[0003] The purpose of the utility model is to provide a combined roller ring for producing aluminum alloy forging rings, so as to solve the problem of high manufacturing cost of special roller rings used for manufacturing special-shaped forging rings.

[0004] The utility model discloses a combined roller ring for producing aluminum alloy forging rings, which consists of an outer ring and a base ring; the outer side of the outer ring is processed with an annular groove; the base ring is in a boss shape, the outer ring is sleeved on the base ring, and a stepped through hole is provided in the center of the base ring; the inner circumference of the outer ring is symmetrically processed with a pair of inner cavities, and the outer circumference of the base ring is symmetrically processed with a pair of outer cavities, the inner cavities and the outer cavities are matched to form a keyway, and a long key is provided in the keyway.

[0005] The beneficial effects of the utility model are:

[0006] This new design utilizes two long keys for a split-type design. When producing forged rings of varying shapes and specifications, only the outer ring needs to be replaced, eliminating the need for integrated manufacturing. This can save over 30% in manufacturing costs. The use of two long keys enhances overall strength and prevents key breakage caused by excessive torque during rolling. The composite rollers used in the production of aluminum alloy forged rings are made of 5CrNiMo or 5CrMnMo hot-working die steel. They can operate at relatively high temperatures while maintaining sufficient strength. BRIEF DESCRIPTION OF THE DRAWINGS
