The principle and application of hydraulic coil decoiler
Hydraulic coil decoiler is an auxiliary equipment for coiling processed coils into rolls. It has applications in many industries, among which the metallurgical industry is the mainstay. The hydraulic coil winding machine is mainly driven by a hydraulic system, so in addition to the core equipment reels, auxiliary reeling equipment, and auxiliary reels, hydraulic cylinders are also indispensable.
In the winding process of the coiler, the product is mainly formed on the reel, the reel is generally driven by the motor, the auxiliary reeling device is generally used to rotate the reeling roller, and the fluid hydraulic cylinder drives the reeling roller to move. To help smooth roll.
There are many types of coilers, which can be divided into three types according to their use and construction. They are coilers with tension reels, usually coiled steel or strip under cold tension; The machine is used for hot coil, cold coil steel plate and strip steel; and wire and small steel coiler, hydraulic coil decoiler belongs to it.
In the process of taking up the wire rod, the coil diameter of the coil winding machine changes, which causes the coiling speed to change continuously. In order to adapt the take-up speed to the rolling speed, and to maintain constant tension during wire production, it is required that the speed of the coiler be adjustable, and the speed range should be adapted to changes in the production speed and coil diameter. For this reason, general use is acceptable. Speed-regulated DC motor drive.
After completion, the coil is removed from the drum of the coiler, so the drum must be cantilevered, and at the same time, in order to ensure the rigidity and strength of the drum shaft, the bending of the spool shaft is reduced, in addition to increasing the drum Outside the shaft size, a rotatable bracket is generally installed at the free end of the drum.
