Embodiment Construction

[0020] The device of the present invention will be further described in conjunction with the accompanying drawings.

[0021] As shown in the accompanying drawings, the repairing device of the present invention includes 1. a C-shaped frame platform; 2. a suspension frame; 3. an oil cylinder; 4. a pressing rod; 5. a pressing plate; (7-1. Connecting rod bracket, 7-2. Connecting rod system, 7-3. Hinge bolt, 7-4. Chuck); 8. Positioning bolt; 9. Base. Chuck 7-4 is divided into upper and lower groups of symmetrical chucks. Firstly, the component is placed on the lower chuck, and the cylinder 3 simultaneously pushes the upper chucks on both sides to go down. The upper and lower pairs of chucks clamp the two sides of the component, and At the same time, the material of the component located in the middle of the two pairs of chucks will be cohesive due to horizontal pressure, and the thickness will increase slightly, and the length will be slightly shortened. As a result, the component ...

Abstract

The invention relates to an aluminum section component contour precision adjusting device and belongs to the field of section bending forming. In the aluminum section component contour precision adjusting process, a traditional three-point bending adjusting method belongs to a one-time shape adjusting manner, deformation in the section thickness direction is unstable, macroscopic wrinkling defectsare easily caused, and the contour precision of an aluminum section component is affected. Directing at the above problems, the adjusting device is designed, the two side faces of a component are clamped by a chuck in a shape adjusting mechanism of the adjusting device and are driven by an oil cylinder to draw close to each other inwards in the horizontal direction, and the length of an inner contour is decreased while the wall thickness of a component inner contour area is increased gradually, so that bending deformation happens to the component till the outer contour precision meets requirements. According to the aluminum section component contour precision adjusting device, by gradually increasing the wall thickness of the component inner contour area, the problem that a material is unstable and wrinkles when a traditional adjusting device is used is solved, a progressive shape adjusting manner is achieved, and the aluminum section component contour precision can be greatly improved.

Description

Technical field: [0001] The invention relates to a device for adjusting and repairing the profile accuracy of aluminum profile components, which belongs to the field of profile bending and forming. Background technique: [0002] Aluminum profile parts are light in weight and meet high strength requirements, so they are widely used in aerospace, automobile and railway transportation and other fields. In recent years, as my country continues to increase investment in railway transportation, rail vehicles such as light rail, subway, bullet train and high-speed rail have been accelerated. In order to reduce the weight of the body and reduce the overall energy consumption, the application of aluminum profiles in rail vehicles is becoming more and more Wider and wider. [0003] In the rail vehicle body, the forming accuracy of the aluminum profile components directly affects the assembly accuracy of the car body and the quality of the vehicle. After the aluminum profile is bent a...
