Aluminum alloy constant-temperature fine die forging process

Abstract

The invention discloses an aluminum alloy constant-temperature fine die forging process, relating to an aluminum alloy die forging process. Aiming at problems of low temperature, waste generation due to overlarge forging blank materials, unstable process and easiness in soaking a mould of the traditional aluminum alloy constant-temperature fine die forming mould, the aluminum alloy constant-temperature fine die forging process comprises the following steps of: 1, determining a size of a forging piece blank material; 2, heating a forging mould and a forging piece blank material; 3, after the material temperature is reached, hoisting a forging piece blank material in a well furnace outside and then placing a first basket of a box furnace, continuously preserving the temperature; 4, smearing graphite lubricant on a mould, then placing the forging piece blank material on the mould; 5, forging and pressing; 6, starting an ejector rod for ejecting a button, ejecting a forming piece, clamping the forging piece by using a material clamp, placing on a counter top; and 7, grinding burrs on the bottom of the forging piece by using a angle grinder cleanly, and placing on the counter top for reducing the temperature. The invention is suitable for aluminum alloy constant-temperature fine die forging.

Description

technical field

[0001] The invention relates to an aluminum alloy die forging process. Background technique

[0002] Isothermal die forging, referred to as isothermal forging, is a die forging in which the die is heated to the deformation temperature of the blank and deformed at a low strain rate. Isothermal forging technology has been maturing since the 1970s, and is widely used in the manufacture of important structural parts of aerospace vehicles, and has achieved very obvious technical and economic benefits.

[0003] Isothermal forging technology is mainly used in the aerospace industry for the production of difficult-to-form material forgings with complex shapes, thin webs and high ribs, and high internal quality requirements on the surface of forgings. Not only that, compared with conventional die forging, isothermal die forging technology is also an energy-saving technology. However, isothermal die forging is only suitable for medium and small batch production of fo...
