Coil tightening machine capable of improving synchronicity

Abstract

The invention discloses a coil tightening machine capable of improving synchronicity. The coil tightening machine comprises supports, a cylinder and roller rack sets, the two sides of the first support and the two sides of the second support are each symmetrically provided with chains, roller racks are driven by telescoping of a piston rod to move on guide rods, and a clamping roller is installed on each roller rack; the roller racks close to the first support are fixed to an upper chain layer of a chain through locking bolts, and the roller racks close to the second support are fixed to a lower chain layer of the chain through locking bolts. According to the coil tightening machine capable of improving the synchronicity, the clamping rollers can make contact with steel coils simultaneously, the labor intensity of on-site construction personnel for air-circuit piping is reduced, and convenience is brought to point inspection and maintenance in the later production process; the number of arranged spare parts in a rolling mill is decreased, and the equipment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of tension coilers, in particular to a tension coiler with improved synchronization. Background technique [0002] The take-up coiler is located between the fast roller table and the slow roller table in the collection area of ​​the strip steel production line. Its function is to position and tighten the steel coils during transportation, which is convenient for packaging and transportation. The tension coiler realizes the advance and retreat of the pinch roller through the expansion and contraction of the cylinder. The winding rollers on both sides rotate in opposite directions, so that the steel coils rotate on the rollers, and the steel coils are tightened with the cooperation of the pinch rollers. [0003] The current tensioner has the following problems: [0004] 1. The action of the clamping rollers on both sides is realized by the movement of two cylinders respectively. There is no connection betwe...

AI Technical Summary

Problems solved by technology

There is no connection between the two cylinders, and it is difficult to ensure the synchronization of the pinch rollers on both sides, so that during the use of the tensioner, one side of the pinch roller is often in contact with the steel coil, while the other side of the pinch roller has not been in contact with the steel coil. The phenomenon of steel coil contact;

[0005] 2. When on-site gas pipeline piping, two cylinders must have two sets of pipeline control respectively, which virtually increases the labor intensity of the on-site construction personnel, and also brings inconvenience to the spot check and maintenance during the operation in the future
