Abstract
Coiler strip is the main production equipment, coiling into its volume, for the production, transport and storage. Cold is characterized by modern high-speed, Large re-direction, the importance of coiler more significant.
Cold strip coiler of the end-use can be divided into the tension coiler and finishing coiler two categories. The tension coiler mainly used for reversible mill, rolling mill, single-mill peace.
Finishing coiler is mainly used for continuous annealing and pickling, Tudu and Slitting, heavy volumes and other production units.
Tension coiler of the requirements is a higher strength and stiffness in order to achieve the tension coiling; reel open, should be able to become a complete circle, to prevent the injured lining strip; quick replacement volumes Extinguishers, to adapt to a variety of thickness, surface coil at the same time demand higher quality and corrective control.
This design applied to single blocks cold rolling mill, the pyramid expansion and contraction for the four-coiler, the aircraft by the motor reducer driven by the hollow shaft and with one of the four sets of pyramid, the four hydraulic cylinders driven by the pyramid, before and after the mobile , Which sets its expansion and contraction on the fan-shaped plate so that the take-up tight inside the strip or release. Pyramid angle of 7 ¡ã 30 '. Under normal conditions of use of lubricating expansion and contraction of the cylinder pressure to achieve the automatic reel necking.
Reel is the weak link in the fan-shaped tail hook block, the tail hook in the pyramid shaft axial effort will have the effect of high bending and shear stress, fatigue easily by the Huai. At the same time, Cone is the main structure and the expansion and contraction of the tank bolt at a disadvantage in the state. Four of using inverted pyramid coiler cone, a significant improvement of the situation in parts of the force, fan-shaped block structure has been simplified.
Key words: coiler, the tension, the four pyramid, automatic necking, inverted cone.
