Intermediate roller structure of six-fold parallel roller straightener roller system

Abstract

The invention relates to a local component of a six-fold parallel roller straightener, in particular to an intermediate roller structure of a six-fold parallel roller straightener roller system. The intermediate roller structure of the six-fold parallel roller straightener roller system comprises working rollers, supporting rollers and intermediate rollers arranged among the working rollers and the supporting rollers. The intermediate roller structure is characterized in that a spiral groove is formed in each intermediate roller, the two ends of each intermediate roller are installed in self-aligning ball bearings, each self-aligning ball bearing is installed on an intermediate roller seat, a gland is closely arranged on the outer side of each self-aligning ball bearing, and each gland ispositioned through an elastic check ring clamped in a hole of the corresponding intermediate roller seat. The intermediate roller structure has the beneficial effects that homogenized spray lubricating liquid can be stored in the spiral grooves, the lubricating effect is enhanced, and the plate surface quality is improved; foreign matter in the roller system can be conveniently discharged, the plate surface machining quality is ensured, and the service life of the working rollers is prolonged; and the intermediate rollers can deform along with the deflection of the working rollers, and the plate straightening requirements of plates with obvious buckling defects and lotus leaf edge defects are met.

Problems solved by technology

The surface quality and machining accuracy requirements of light alloy sheet metal are relatively high during the processing process. If foreign matter falls into the roll system of the traditional leveler, it will adhere to the work roll, intermediate roll or backup roll, affecting the work roll, intermediate roll, etc. service life of rolls and back-up rolls, and damage to the plate surface of the processed plate

The original plate shape of the light alloy quenched plate is poor, with obvious buckling defects and ruffle edge defects. During the leveling process, the work rolls and intermediate rolls are required to be able to adjust a certain deflection curve. The traditional leveling machine intermediate roll and The middle roller seat is rigidly connected, which is not conducive to adjusting the deflection curve of the middle roller
