7 Rolls Levelling Machine

Overview of 7 Rolls Levelling Machine

The 7 Rolls Levelling Machine is a multi-roller straightening equipment designed for correcting curved and deformed metal plates after rolling processing. With seven leveling rollers arranged in a staggered layout, this 7 Rolls Levelling Machine applies continuous alternating extrusion force to eliminate internal stress and surface warpage of raw steel sheets. It is equipped with front and back feeding roller tables to realize automatic material conveying into the leveling area, and the matched driving motor provides power for synchronous roller rotation. The integral heavy frame structure of this 7 Rolls Levelling Machine bears cyclic extrusion load during continuous operation. This equipment completes one-pass multi-point pressing leveling, cutting repeated clamping operations, and fits continuous batch straightening of carbon steel, alloy steel, and stainless steel plates for subsequent cutting and forming procedures in metal processing lines.

Product Introduction

Core Advantages of 7 Rolls Levelling Machine

- Seven-staggered roller layout: The 7 Rolls Levelling Machine achieves multi-point repeated bending to remove residual stress and plate warpage in a single feeding process.
- Equipped with matching feeding roller conveyor: This 7 Rolls Levelling Machine realizes uninterrupted automatic feeding and discharging.
- Integrated heavy frame structure: Reduces structural deformation under long-time continuous leveling load.
- Centralized driving system: Keeps synchronous rotation of all leveling rollers on the 7 Rolls Levelling Machine to maintain consistent pressing force on the plate surface.

Product Features of 7 Rolls Levelling Machine

The 7 Rolls Levelling Machine features seven staggered leveling rollers that form a repeated bending route to adjust the flatness of irregular deformed metal sheets. Front and rear auxiliary roller tables on this 7 Rolls Levelling Machine connect upstream cutting and downstream forming equipment for assembly line matching. An independent drive unit connects with the transmission mechanism to control the operating speed of the whole roller group. The versatile structural design of this 7 Rolls Levelling Machine adapts to leveling processing for multiple common industrial metal sheet materials.

Application Scenarios of 7 Rolls Levelling Machine

The 7 Rolls Levelling Machine is widely arranged in steel processing production lines, pressure vessel manufacturing factories, steel structure workshops, and environmental equipment processing plants. This 7 Rolls Levelling Machine handles flatness correction of steel plates after hot rolling, plate cutting, and coiled uncoiling, preparing qualified flat blanks for subsequent plate rolling, blanking, and welding production.

Operation Notes for 7 Rolls Levelling Machine

- Place plates at the center of the feeding roller table on the 7 Rolls Levelling Machine to avoid unilateral stress and partial incomplete leveling.
- Check all roller surface cleanliness before startup and clear attached metal scraps.
- Run a no-load test to verify synchronous rotation of each roller before formal production.
- Supplement lubricating oil for transmission bearings and gear parts according to a fixed maintenance cycle.
