Embodiment Construction

[0017] To implement the rolling and heat treatment method of the 6061 aluminum alloy ring according to the present invention, it is necessary to provide equipment such as a forging heating furnace, a press, a ring rolling mill, a heat treatment furnace, and a manipulator.

[0018] The steps of this method are as follows:

[0019] Take a 6061 aluminum alloy bar of a certain specification, heat it to a deformation temperature of 420°C, then upset and punch; put it into a ring rolling mill for pre-rolling, the pre-rolling deformation is 25% to 30%, and the temperature during pre-rolling should be ≥ 400°C; reheat to the deformation temperature of 420°C for final rolling, the final rolling deformation is 30% to 40%, and the final rolling temperature should be ≥ 400°C;

[0020] Put the ring into the heat treatment furnace, heat it to 535°C, keep it warm for 5 hours, carry out solution heat treatment, take it out and air cool;

[0021] Then put the ring into the heat treatment furna...

Abstract

The invention discloses a rolling and heat treatment method for a 6061 aluminum alloy ring part. The rolling and heat treatment method comprises the following steps: firstly, taking a 6061 aluminum alloy bar of a certain specification, heating the 6061 aluminum alloy bar until a deformation temperature, and then carrying out upsetting, punching, pre-rolling and finish rolling, thereby obtaining the 6061 aluminum alloy ring part, wherein the deflection of pre-rolling is 25%-30% and the deflection of finish rolling is 30%-40%; and further, carrying out heat treatment by using a heat treatment system that has a solution temperature at 535 DEG C and an aging temperature at 162 DEG C by preserving heat for more than 5 hours, and preserves heat for 8-10 hours. The method is capable of improving the forming quality of the ring part and avoiding a mixed crystal phenomenon. The method is used for the rolling and het treatment of the 6061 aluminum alloy ring parts.

Description

technical field [0001] The invention relates to a rolling and heat treatment method, in particular to a rolling and heat treatment method of a 6061 aluminum alloy ring. Background technique [0002] 6061 aluminum alloy is an A1-Mg-Si series heat-treatable aluminum alloy, which has the characteristics of good formability, strong corrosion resistance, medium strength, light specific gravity, and good welding performance. It has good plasticity in a hot state and can be used to manufacture Thin-walled and hollow extruded products with complex structures can also be subjected to die forging, stretching, deep drawing and various large deformation operations, so they are widely used as structural materials in aviation, aerospace, shipbuilding, transportation, construction and other fields. Such as aircraft engine blades, helicopter rotor beam. [0003] The rolling and heat treatment methods have a great influence on the forming of 6061 aluminum alloy rings. If the rolling and hea...
