Title:
COMPLEX CAVITY PROFILE STRAIGHTENING AND STRETCHING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/142348
Kind Code:
A1
Abstract:
A complex cavity profile straightening and stretching device, comprising guide rails (1), a first hydraulic device (2), a main body component (3), a downward pressing mechanism (4), a rotating arm (5), a second hydraulic device (6), a special clamp (7), and a third hydraulic device (8). The second hydraulic device is provided on the upper portion of the main body component, and is connected to the rotating arm; the rotating arm is fixedly connected to the downward pressing mechanism; a clamping pad (11) working in conjunction with the downward pressing mechanism is provided below the downward pressing mechanism; the special clamp is connected to the third hydraulic device; the special clamp comprises a fixed clamping head group (71) and a movable clamping head group (72); and the fixed clamping head group comprises several fixing clamping heads (711) spaced apart from each other by a predetermined distance. A complex cavity profile straightening and stretching method is further comprised. By using the device or method, connection ribs (14) of an aluminum material can be clamped and fixed by means of the special clamp, a cavity profile can be effectively straightened and stretched, and the deformation amount of a clamping part is small.
