The tilting fingers permits a continuous rod feed into the cold rolling, drawing and stretching line. They are composed of a pair of suitably shaped arms, whose structure is made of steel pipes internally filled with sand in order to reduce the noise during operations, which can turn of 90 degree on a vertical plane to reach two (2) different positions: vertical and horizontal. In the horizontal position, the fingers allow the load of the wire rod taken directly from the stock area using an overhead crane or a forklift. When the wire rod is loaded, the fingers rotates to the vertical position, ready to allow the unwinding of the wire towards the pay-off tower. Several models of tilting fingers are available in function of the dimensions and weight of the wire rods and of the height of the pay-off tower.
The pay-off tower of Vertical Horizontal pay-offs permits vertical unwinding high-speed without the development of tangles/snarls and interruption of the production. Hydraulic payoff standing is composed of a sturdy steel frame with an adequate base frame. On the top of the frame is positioned a mobile trolley, moved by an electric hoist, with a de-winding wheel. Payoff Stand system permits an easy wire untangling if knots occur during operations. Sides of tower are clad in thin gouge mild steel sheeting in order to contain dust, which is collected at the basis of the tower by a metal slide forward between the fingers. The stand of Wire Payoff Machines is furnished with a safety device that automatically stops the cold rolling line in case of emergency (knot presence).Wire Drawing Process A specific sensor system of new generation, which is adjustable directly by receipt from the payoff desk without the need of lower the upper basket, permit to set the sensor for the different wire diameters recording dedicated receipts. The benefits of Vetical type Payoff Unit can be summarized in an extreme flexibility and speed in production changes and zero downtime because the adjustments (if needed) are made in running without stopping the machine. The position of the unwinding trolley is automatically secured by a pneumatic cylinder that double-checks the correct anchoring of the hook to the structure and allow also its opening/closing. The hoist chain tension is controlled by a sensor preventing overloading of the chain. Several models of pay-off towers are available in function of the speeds of the line (Vetical type Payoff Unit for Wire Drawing Process) and the layout of the company.
