The function of a leveling machine in welded pipe equipment is to correct and form, and it will be used in the early stages of the welded pipe production line's operation. So, what are the specific functions of the leveling machine, and what are the common problems encountered during use?

When making products, after uncoiling the steel strip coil, the leveling machine flattens the curved steel strip.
There are three recommended types of strip leveling machines for cold-formed steel: five-roll, seven-roll, and nine-roll. Different materials correspond to different types of leveling machines. Open end cold-formed steel mostly uses a five-roll type, while closed end cold-formed steel mostly uses a seven-roll type.
In small and medium-sized welded pipe production lines, the normal use is a five-roll or seven-roll leveling machine. Some welded pipe lines that use thin steel strips do not have leveling machines and can quickly transport the steel strips to the storing accumulator. The strip steel is straightened by bending between the two columns of rollers of the leveling machine. The more cycles of repeated bending, the smoother the leveling process and the higher the quality of leveling.
The operation of the leveling machine is still a bit complicated, and various problems may be encountered during use. What adjustments do we need to make?
During use, there may be situations where the rollers of the leveling machine are worn out, or when applying excessive pressure but still unable to level, it is common to replace the rollers. If the steel strip is uneven and wavy after straightening, the pressure of the upper frame needs to be adjusted immediately to increase the pressure of the entire upper roll. Of course, when making adjustments, it is important to pay attention to personal safety!
The reason why the end of the steel strip bends downwards when it emerges from the leveling machine is because the position of the lower roller at the outlet end is too low. It is recommended to raise it appropriately; When the steel strip emerges from the leveling machine, the end bends upwards due to excessive pressure from the upper roller. It is recommended to adjust the lower roller at the outlet end to reduce the pressure and achieve the desired leveling effect.
