Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] A method for manufacturing a 2219 aluminum alloy high-tube special-shaped ring forging with an inner flange, which is characterized in that it includes the following steps:

[0020] 1) Making rectangular ring embryos

[0021] Saw the bar as required, heat the sawed bar to 450°C-510°C with a gas furnace or an electric furnace, upsetting and punching a rectangular ring billet 2 under the heat preservation state, and the heat preservation time is the effective time of the bar. Thickness × 15min / 10mm.

[0022] 2) Making special-shaped ring embryos

[0023] Put the rectangular ring blank 2 on the special-shaped horse bar 4, put the special-shaped horse bar 4 flat on the horse stand 5, place the clapper 1 on the outer circle of the middle part of the rectangular ring blank 2, the outer circle of the rectangular ring blank 2 and the clapper 1 The lower surface of the con...

Abstract

The invention relates to a manufacturing method of a 2219 aluminum alloy strap inner flange high cylinder special-shaped annular forging. The manufacturing method comprises such steps as manufacturing of a rectangular annular blank, manufacturing of a special-shaped annular blank, pre-rolling of the special-shaped annular blank and manufacturing of a final forging; in the step of manufacturing the special-shaped annular blank, the rectangular annular blank coats a special-shaped lever; the special-shaped lever is flatly placed on a mandrel supporter; a beating plate is placed on the outer circle of the middle part of the rectangular annular blank; the outer circle of the rectangular annular blank is contacted with the concave lower surface of the beating plate; two ends of the annular blank are not covered by the beating plate; an upper anvil of a press is descended; the pressure is applied to the rectangular annular blank through the upper surface plane of the beating plate; meanwhile, a manipulator rotates the rectangular annular blank; under extrusion of the special-shaped lever and the beating plate, the inner diameter of the middle part of the rectangular annular blank is increased; the wall thickness is thinned; and the blank is separated to two ends to obtain the special-shaped annular blank. The beating plate is added between an upper anvil of the press and the annular blank, so that the blank is separated in the blank manufacturing phase, the shape and the size of the annular blank are more close to the shape and the size of a target forging, the subsequent processing difficulty is reduced, the period is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to a manufacturing method and a mold of a 2219 aluminum alloy belt inner flange high cylinder special-shaped ring forging. Background technique [0002] 2219 aluminum alloy has the characteristics of high strength, good low temperature and high temperature mechanical properties, high fracture toughness, good stress corrosion resistance, etc., and has been widely used in aviation and aerospace industries. [0003] 2219 aluminum alloy with inner flange high tube special-shaped ring forging is a kind of parts commonly used in aero-engines. At present, there are two main production methods for high-tube special-shaped ring forgings of 2219 aluminum alloy with inner flange: 1) obtained by crimping and welding plates; 2) obtained by machining rectangular rings. [0004] Using the first method, the material structure at the welding seam of the forging is different from other areas, which will cause the performance of the forging to decl...
