Embodiment 1
[0054] This embodiment is used to illustrate the aluminum extrusion material forming method disclosed in the present invention, which includes the following steps:
[0055] Obtain the 6082-T6 aluminum extruded tube provided by a supplier. The 6082-T6 aluminum extruded tube has been artificially aged and has a hardness of 128HV. The time is 10s, and then the water quenching treatment is carried out. The bending and forming of the pipe was completed within 1 day. It was observed that there was no cracking after the pipe was formed, and the precision control was good. The hardness test was performed on the performance of the parts after being parked at room temperature for 0.5d, 1d, 2d, 3d, and 7d, and the test results were recorded in Table 1. From the test results in Table 1, it can be seen that after 3 days of parking, the deformed area of the part after bending gradually recovered to a performance level comparable to that of the surrounding unheated, undeformed area, such ...

Abstract
In order to overcome the problems of complex process and high equipment cost in the existing aluminum extrusion forming process, the present invention provides an aluminum extrusion forming method, which includes the following steps: obtaining the artificial aging treated aluminum extrusion; The area to be deformed of the aluminum extrusion is heated, and the heating temperature is higher than the solid solution temperature of the β'' phase of the aluminum extrusion, and lower than the Mg of the aluminum extrusion. 2 The solid solution temperature of the Si phase; perform water quenching on the heat treatment area; bend and deform the area to be deformed of the aluminum extrusion within 2 days of completing the water quenching, and keep the aluminum extrusion at room temperature within 2 days of completing the water quenching state. The aluminum extrusion material forming method provided by the present invention makes full use of the heat treatment equipment of aluminum extrusion forming for artificial aging treatment, and no further heat treatment is required after the heat treatment of the bending area, that is, the bending processing manufacturer does not need to invest additional heat treatment equipment, It effectively reduces the manufacturing cost of aluminum extruded parts, and has good operability and economic value.
Description
technical field [0001] The invention belongs to the technical field of aluminum alloy processing, and in particular relates to an aluminum extruded material forming method. Background technique [0002] Lightweight is one of the development directions of automobiles. Due to its light weight and easy extrusion of different cross-sectional shapes, aluminum alloys are widely used in body structural parts such as front longitudinal beams and floor beams. Most of the aluminum extrusions on automobiles are 6-series or 7-series materials that can be strengthened by aging, and the use state is mainly in the artificial aging state (T5, T6 or T7), which has a higher strength and crash performance. Taking the anti-collision beam as an example, the current mainstream anti-collision beam material is 6082, and the use state is T6 state, which can obtain a yield strength close to 300MPa, which is much higher than the T4 state (about 120MPa) without artificial aging. [0003] However, whi...
