Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that "up" and "bottom" and "left" and "right" in this specification indicate the relative positional relationship between the two.

[0019] Such as image 3 , Figure 4 Shown, the forging method of a kind of deformed short T-shaped blank of the present invention, the method comprises the following steps:

[0020] In the first step, put the lower end of the rod-shaped blank 3 into the cavity of the pier thick lower die 5, put the upper end into the cavity of the pier thick upper die 4, and press the pier thick upper die 5 along the direction close to the pier thick upper die 5. Die 4, until a protrusion 61 is formed between the upper end and the lower end of the rod-shaped blank 3, thereby forming the first intermediate blank 6;

[0021] In the second step, the first intermediate blank 6 is placed flat on the flat lower mold 10, and t...

Abstract

The invention provides a forging method for deformed short T-shaped blank, and the forging method solves the problem that forming of deformed short T-shaped blank is difficult, and relates to the technical field of forging-pressing. The forging method for the deformed short T-shaped blank comprises the following steps: a first step of placing the lower end part of rod-shaped blank into a heading lower mould cavity, placing the upper end of the rod-shaped blank into a heading upper mould cavity, pressing a heading upper mould along a heading lower mould until a bump part is formed between the upper end part of the rod-shaped blank and the lower end part of the rod-shaped blank, thereby forming first intermediate blank. The forging method solves the difficult forming problem of the deformedshort T-shaped blank. An inner metal flow line of the integrally formed deformed short T-shaped blank is good, and an aviation product processed by the inner metal flow line is good is in integral performance, so that weight of the aviation product can be relieved on the premise of meeting performance requirements, and therefore, product competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a forging method for a deformed short T-shaped blank. Background technique [0002] In aviation parts products, there are often some parts with particularly complex shapes, such as some parts with deformed short T-shaped outlines. Such as figure 1 , figure 2 As shown, the shape and structure of this kind of deformed short T-shaped parts are characterized by the short vertical rod part 1 and the long head rod part 2. The material required for the head rod part 2 is much larger than that required for the vertical rod part 1, and the head rod The left end portion 21 and the right end portion 22 of the portion 2 are asymmetrical (the length, thickness, or / and slope of both sides of the left end portion 21 and the right end portion 22 are also inconsistent). [0003] The blank of conventional T-shaped parts (the vertical rod part 1 is long, the head rod part 2 is short, the materi...
