Detailed Description

The invention will be further explained by way of example with reference to the accompanying drawings.

Referring to fig. 1-7, a stelmor air-cooled wire coil pushing device for high-speed wires is arranged on two sides of an air-cooled roller way, the air-cooled roller way comprises a plurality of conical rollers 7 arranged in parallel, and each conical roller 7 comprises a cylindrical roller 71 and two cones 72 arranged oppositely on the cylindrical roller 71; the coil pushing device comprises a hydraulic cylinder 1, a cone pulley support 3, a guide pulley shaft 4, a coil pushing pulley 5 and a base 6, wherein the hydraulic cylinder 1 is fixed on the base 6, a lever of the hydraulic cylinder 1 is in driving connection with the cone pulley support 3, the cone pulley support 3 is U-shaped, two ends of the coil pushing pulley 5 are respectively fixed in the U-shaped cone pulley support 3 through the guide pulley shaft 4, one end of the coil pushing pulley 5 is conical, and the other end of the coil pushing pulley 5 is cylindrical.

In this embodiment, and with reference to FIG. 3, the dimensions of cone 72 are 108mm inside diameter, 280mm maximum outside diameter and 120mm width. The cone 72 is cut into two half cones from the middle, and the two half cones are connected and fixed on the cylindrical roller 71 through countersunk bolts to form the cone roller 7.

Referring to fig. 2, the push-rolling wheel 5 provides lateral thrust for the steel coil on the roller way, the maximum outer diameter of the conical part of the push-rolling wheel 5 is 295mm, the minimum outer diameter is 85mm, the conical inclination angle is 45 degrees, the length of the cylindrical part is 120mm, two thrust bearings are arranged on the upper part and the lower part of the push-rolling wheel 5, and the push-rolling wheel is fixed on the cone pulley bracket 3 by a hollow shaft (capable of being added with lubricating grease).
