Rectifying device for large-sized unstable aluminum alloy sections

Abstract

A rectifying device for large-sized unstable aluminium alloy sections comprises a symmetric arrangement roll system comprising 12 straightening rolls, the straightening rolls are connected with straightening roll full-transmission driving devices and are mounted in a combined rack in a top-bottom symmetric arrangement manner, upper ends of the straightening rolls are equipped with six upper roll press-down devices, four lower roll press-up devices are arranged at the lower ends of the straightening rolls, two ends of the rack are connected with a fixing support in a matched manner, the fixing support is connected with a foundation screw, the adjustment of the upper roll press-down devices and the lower roll press-up devices allow for the adjustment of roll gaps and inflection amount, the straightening roll full-transmission driving devices drive the straightening rolls to realize gripping and straightening of sections via the twelve straightening rolls and rectification of cross section of the can be realized through the symmetric straightening rolls. Straightening accuracy and section size accuracy of the existing sections can be increased, and scrap from instability and surface strain caused during straightening process can be avoided for large-sized irregular aluminium and aluminum alloy sections.

Description

technical field [0001] The invention relates to the field of non-ferrous metallurgical equipment, and in particular to a straightening device for large-scale and unstable aluminum alloy profiles, which is mainly used for high-precision straightening of large-scale aluminum and aluminum alloy quenched profiles and profiles with complex cross-sections. Background technique [0002] The number of straightening rollers in traditional straightening equipment for aluminum and aluminum alloy profiles ranges from 7 to 11 rollers. The upper and lower straightening rollers are arranged in a staggered manner, and the transmission mode is semi-transmission, that is, only the lower roller is driven, and the upper roller is a passive roller. . There are defects that the straightness of the profile after straightening is low, and the section of the profile cannot be corrected accurately, especially when straightening large-sized profile, the phenomenon of profile instability and scrapping ...
