Abstract

A rolling method of an L-shaped cross-section special-shaped ring, which includes: step A, preparing a non-contoured ring blank, and step B, utilizing a radial-axial ring rolling machine to roll the ring blank The pieces are prepared as the L-shaped cross-section profiled ring. The rolling method of a special-shaped ring with an L-shaped cross-section provided by the present invention finds a specific mathematical relationship by analyzing the axial flow law of the metal during the rolling process, so that the non-equal-height ring-shaped blank can be used in the rolling process. The defect-free L-shaped profiled ring is obtained under the bi-directional rolling of the radial-axial ring rolling machine. While effectively solving the problems existing in the prior art of using contour blanks in the background art, the production efficiency and yield rate are greatly improved.

Description

Technical field [0001] The present invention relates to the field of machining technology, in particular to a rolling method for an L-shaped cross-sectional special-shaped ring. Background [0002] Figure 1 Schematic diagram of the rolling process principle for existing L-section special-shaped ring parts; See Figure 1 As shown, the overall height of the final ring part is H1, including step part A " and cylindrical part B ", the outer circle diameter of the step part A " is D3, the diameter of the inner hole is D2, the height is H2, the outer circle diameter of the cylinder part B "is D1, the existing process of rolling L-sectional special-shaped ring parts, the initial blank used is mainly two types: [0003] (1) Rectangular section initial blank of equal height as the final special-shaped ring; [0004] (2) The initial blank of the special-shaped section at the same height as the final special-shaped ring part. [0005] For contour rectangular section initial blanks, the init...
