High-speed wire rolling mill generally refers to the wire rod mill with the maximum rolling speed higher than 40m/s, which is a comprehensive product of metallurgical technology, electric control technology and machinery manufacturing technology. In the high-speed wire rod production line, after the wire is rolled, it needs to be spun into a circle by the wire spitting machine in order to complete the transformation from straight wire to coiled wire. The wire spitting machine is one of the key equipment for high-speed wire production, but also an important bottleneck that restricts the further speed of high-speed mills, the spitting of the wire directly affects the physical quality of high-speed wire, spitting machine with its special shape of the structure with a certain speed, the high-speed movement of the straight status wire into a stable, evenly spaced coil. With the increase of wire rolling speed and output, the requirements of the wire spitting machine to be higher and higher, so many high-speed wire rod production enterprises in the production of unstable spitting circle, and affect the quality of products and production line. Spitting principle 1. The structure of the spinning machine High-speed wire rod plant spitting machine for the horizontal structure, located in the finishing mill after the control of the cooling line between the water-cooled box and the cold control roller channel. The spitting machine consists of transmission device, hollow shaft, spitting disk, spitting tube, bevel gear and other components. The spitting machine is driven by a motor and driven by a pair of bevel gears meshing in the gear box to rotate the hollow shaft, the spitting tube is mounted on the spitting disk, and the spitting disk is connected to the hollow shaft by bolts. 2. Analysis of the spitting process of the spitting machine When the spitting machine is working, the wire is fed into the hollow shaft of the spitting machine by the spitting machine inlet duct through the pinch feed rollers in front of the spitting machine. The hollow shaft drives the spitting disc and spitting tube to rotate together, so that the wire entering the hollow shaft spits out coils through the rotating spitting tube along the tangential direction of the spitting tube exit circumference and pours smoothly on the air-cooled roller path to form a continuous coil. When the wire passes through the high-speed rotating spit pipe, it is gradually bent and deformed with the shape of the spit pipe by the positive pressure of the spit pipe wall, sliding friction, the thrust of the finishing mill and pinch feed rollers, and its own centrifugal force. From a straight line movement, it gradually bends and reaches the required curvature at the exit of the spitting tube, forming a spiral coil and spitting out in a uniform and smooth circle.
