A combined straightening machine

Abstract

The invention discloses a combined type straightening machine. The combined type straightening machine comprises at least three detachable straightening roll devices. Each straightening roll device is connected with a drive device. Every two adjacent straightening roll devices are movably connected and arranged in an up-down staggered mode. Plates or profiles are straightened by the straightening roll devices by penetrating through the straightening roll devices which are arranged in the up-down staggered mode. According to the combined type straightening machine, the straightening roll devices are movably connected and arranged in the up-down staggered mode, and compared with an existing straightening machine of a fixed structure, the roll number and the roll distance of the straightening machine can be changed by increasing or decreasing the number of the straightening roll devices according to needs without replacing the whole straightening machine. The weight of a machine frame of the straightening machine can be lowered, the size can be decreased, the rigidity can be improved, and the straightening technological requirement of the plates or profiles of different thicknesses can be met. Moreover, each straightening roll device is connected with the corresponding drive device, and the roll speed of each straightening roll device can be automatically adjusted, so that the plates or the profiles are better straightened.

Description

technical field [0001] The invention relates to a plate or profile straightening equipment, in particular to a combined straightening machine. Background technique [0002] In rolling production and processing, it is necessary to use a straightening machine to straighten and flatten metal sheets or profiles to make them have the required flatness. At present, the structure of the profile / plate straightening machine used is as follows figure 1 As shown, the main feature is that several straightening rollers installed in the bearing housing are divided into upper and lower layers and arranged alternately. They are placed in a frame composed of four columns and upper and lower beams. Adjust the device to change the horizontal position of the upper straightening roller group. When the metal plate passes through the roll gap between the upper and lower straightening rollers, it will finally reach straightness after repeated bending under the action of the upper and lower straigh...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a combined straightening machine, which adopts the form of connecting multiple straightening roller devices. Compared with the existing straightening machine with fixed structure, the present invention can solve the problem of the number of straightening rollers in the existing straightening machine. Unable to change and limited adjustment range of roller distance, heavy frame, large size, limited rigidity and complicated replacement of straightening rollers, etc.
