Four-roller straightening machine for aluminum alloy sections with rib plates

Abstract

The aluminum alloy profile four-roller straightening machine with the rib plates comprises a rack, two straightening roller systems which are symmetrically arranged left and right are arranged in the rack, and each straightening roller system comprises an upper roller system and a lower roller system; each of the upper roller system and the lower roller system comprises a bearing seat, a roller shaft, a driving key and at least one roller ring sleeved on the roller shaft, and roller ring locking devices fixed on the driving key are respectively mounted at two ends of the roller ring; the two bearing seats of the lower roller system are respectively mounted at the bottom of the rack, and the two bearing seats of the upper roller system are respectively positioned above the two bearing seats of the lower roller system; four opening degree adjusting devices are installed on the top of the machine frame, and the output ends of the opening degree adjusting devices are connected with bearing seats of the upper roller system respectively. The straightening machine provided by the invention can be used for straightening plates or profiles with rib plates.

Description

technical field [0001] The invention relates to the technical field of plate or profile straightening, in particular to a four-roller straightening machine for aluminum alloy profiles with ribbed plates. Background technique [0002] With the development of aerospace and transportation equipment manufacturing technology, the requirements for the overall performance and size specifications of ribbed plates for large curved surfaces of non-ferrous metals or alloys are getting higher and higher. Direct technology has not yet been formed. [0003] For example, the application number is 201210138335.0, and the Chinese invention patent titled "a four-six-roll leveling machine" discloses a four-six-roll leveling machine. This equipment can only level the strip, but cannot straighten the ribbed plate. straight. [0004] For example, the application number is 201820109067.2, and the Chinese utility model patent titled "Aluminum Alloy Forming Correction Device" discloses an aluminum...

AI Technical Summary

Problems solved by technology

The device only has a pair of upper and lower shaping rollers, which is only suitable for profiles with small length and small correction margin. For profiles with long length and large correction amount, the production efficiency is low; For threaded connection, relative rotation between the shaping roller and the connecting rod is required to adjust the distance between the shaping rollers, and the operation is cumbersome; there is no device for eliminating the assembly gap between the upper and lower bearing seats of the device. During the straightening process, the assembly gap has a great influence on the straightening accuracy. will have an indirect impact
