Embodiment Construction

[0010] Below in conjunction with example the present invention is described in further detail.

[0011] The structural part of a large military aircraft is a Y-shaped branch. The cross-sectional area of ​​the two branches is 203mm×80mm, the length of the branches is the same 700mm, and the angle between the branches is 60°. The feeding specifications are: Carry out forging according to the technical scheme among the present invention:

[0012] (1) Blank preparation:

[0013] Will The bar is made into a rectangular blank of 1400mm×440mm×100 by reforming forging.

[0014] (2) slotting:

[0015] In the length direction, divide the 440mm in the width direction into two parallel branches with a width of about 215mm by water cutting, wire cutting or sawing machine. Form two arms close together.

[0016] (3) Punching and splitting:

[0017] Put the above-mentioned blank on the flat anvil, and choose a diameter of The punch punches. When punching, the two arms will automati...

Abstract

The invention relates to a forging method, in particular to production of various Y-shaped blanks made of plastic forming materials. Through the forging method for manufacturing the Y-shaped blanks, the problems that the Y-shaped blanks are difficult to manufacture, boundary dimensions are inaccurate, the utilization rate of materials is low, macroscopic streamlines do not follow outlines, and energy is wasted are solved. In all links of forging operation, plate blank manufacturing, the lengths of kerfs and the positions of punched holes can be accurately controlled, and thus the outlines and dimensions of the Y-shaped blanks are easily controlled, and mass production is facilitated. The working procedures are simple, the forging heating number is small, and waste of energy for forging heating and consumption caused by self-heating of the materials are reduced. The dimensions of the blanks are easily controlled, and the maximum utilization rate of the materials can be achieved. The obtained Y-shaped blanks can maintain the original forging streamlines, and finally produced forgings can have good anti-fatigue ability.

Description

technical field [0001] The invention relates to a forging method, in particular to the production of Y-shaped blanks of various plastic forming materials. Background technique [0002] With the improvement of forging technology, parts processing technology and corresponding equipment capabilities in the aviation manufacturing industry, the design of aircraft parts is also constantly developing in the direction of large-scale and integrated. For the good performance of important parts and convenient processing, high precision is generally required when the parts involve forgings, and die forgings are required. Due to the complex shape of die forgings for aircraft structural parts, it is very difficult to produce forging blanks, especially forging blanks with branch-like characteristic shapes (the blank is Y-shaped as a whole or partially). At present, this kind of Y-shaped bifurcated blank is mostly made by forging the bar into a square billet, dividing the material at a qua...
