Strip stretch bending leveller

Abstract

The invention discloses a strip stretch bending leveller. The leveller comprises a stand housing, two bending roll systems, two levelling roll systems, four roll system gap adjusting mechanisms, roll change devices, quick opening devices, guide rolls and a tension measuring roll, wherein six windows are arranged in the stand housing and are respectively correspondingly provided with a 1# upper bending roll set, a 1# lower bending roll set, a 2# upper bending roll set, a 2# lower bending roll set, a 1# levelling roll set and a 2# levelling roll set up and down from left to right; the machine is provided with standby roll sets with diameters different from the diameters of the two bending rolls; the roll change devices are arranged on the top of the stand housing; and connecting rods are arranged between the ends of the roll change devices and the ends of the two bending roll systems. The leveller has the following effects: the working rolls in the bending roll sets have different diameters and can be freely combined; the thickness range of the levelled strip is wider and the levelling effect is better; the roll sets have longer lives; only the working rolls in the bending roll sets have different diameters and the intermediate rolls, supporting rolls and shaft end supports are shared; and the leveller is equipped with the roll change trolleys, thus realizing quick roll change.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a stretching and bending straightening machine for thin strips such as steel strips, stainless steel strips, and colored strips in cold rolling production. Background technique [0002] The stretch bending straightening machine is widely used in the production of thin strips such as steel strips, aluminum strips, and copper strips. The plate shape can reduce the deviation and vibration of the strip in the subsequent production process, and provide favorable conditions for continuous production; it can also eliminate the yield platform of the strip to avoid slip lines during stamping and forming. The models used in the existing production include two pulls and one straightening, two pulls and two straightenings, but because the whole machine is a fixed structure, the roll system and roll diameter used are fixed, and there are no spare rolls with different diameters that can be replaced. ...

AI Technical Summary

Problems solved by technology

The models used in the existing production include two pulls and one straightening, two pulls and two straightenings, but because the whole machine is a fixed structure, the roll system and roll diameter used are fixed, and there are no spare rolls with different diameters that can be replaced. Therefore, the thickness range of the straightening strip is limited, affecting the quality and precision
