1. Definition and use
Uncoiler is a special equipment for sheet metal leveling. It is mainly used for leveling steel plates and uneven plates, and can be composed of uncoiling, leveling, shearing production lines and other sheet products production lines according to relevant configurations. As the core component of the uncoiler, the uncoiler drum plays a role in supporting the strip steel and uncoiling the strip steel to establish the post-tension of the unit.
2. Structure and working principle
The uncoiler drum is mainly composed of main shaft, quadrangular pyramid shaft, sector plate, pull rod, pull rod shear, rotating oil cylinder, Half coupling and general cap. Its working principle is driven by a motor or a hydraulic motor to rotate, and at the same time use an expansion and contraction rotating cylinder to adjust the inner diameter of the drum to adapt to steel coils of different diameters. When the steel coil is placed on the drum, the inner diameter of the drum is expanded and the steel coil is clamped by the expansion and contraction mechanism, and then the uncoiler starts to rotate, and the steel coil is gradually unwound and sent to the subsequent processing equipment.
3. Key technologies
Expansion and contraction technology: adjust the inner diameter of the drum by hydraulic or mechanical means to adapt to steel coils of different specifications.
Rotational stability: When the reel rotates at high speed, it needs to maintain good stability to reduce vibration and noise.
Strength and rigidity: As a key component of load bearing and transmission, the drum needs to have sufficient strength and rigidity to bear the weight of the steel coil and the centrifugal force during rotation.
