Embodiment Construction

[0032] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] An embodiment of the present invention will be described below in conjunction with the accompanying drawings. The outline size of the frame is 1528mm×1352mm. The preparation method of the TA15 titanium alloy large frame die forging member with ear pieces at the upper end and the right end is as follows:

[0034] (1) V-shaped blank billet: choose a bar with a diameter of Φ400mm, and blank it after upsetting and drawing to obtain a slab with uniform thickness. By applying pressure on the slab, a V-shaped blank is prepared. The pressure acts on the corresponding V-shaped blank. The bottom of the bottom, wherein, the included angle and extension length of the V-shaped blank are corresponding to the included ang...

Abstract

The invention relates to a large-scale solid-forging metal framework with lugs and a manufacturing method thereof. The manufacturing method is particularly suitable for materials like titanium alloy which is hard to deform. The manufacturing method comprises the steps of (1) blank making, (2) pre-forging, (3) pre-forging blank finishing, (4) die forging forming of final forging pieces, and therefore the large-scale solid-forging metal framework with the lugs is obtained. The V-shaped waste blank design method is adopted, a cavity can be well filled, the problem that a forge piece of the large-scale metal framework with the lugs is difficult to form is solved, the manufacturing of a V-shaped waste blank is simple, and the forming effect is good. The forge pieces are mainly applied to the industrial fields like aviation, aerospace and petrochemical engineering.

Description

technical field [0001] The invention relates to a large-scale integral forged metal frame and its preparation technology, in particular to a large-scale integral forged metal frame with ear pieces and its preparation method, especially suitable for the preparation of titanium alloy large-scale components, and can also be applied to aluminum alloy or other integral parts Materials with high performance requirements belong to the field of material science and technology. Background technique [0002] A forging is an object in which metal is pressured and plastically deformed to obtain the required shape or appropriate compression force. Metal can improve its structure and mechanical properties after forging. Forging can ensure the continuity of metal fiber structure, make the fiber structure of forgings consistent with the shape of forgings, and the metal streamlines are complete, which can ensure that forged parts have good mechanical properties. with long service life. Aft...
