Problems solved by technology

During the coiling process, the connecting bolts and screw holes of the two are in a state of alternating tension and compression stress, and the replacement of the fan-shaped plate also requires the removal of the extension shaft and the axial fixing bolts. Therefore, the threaded blind holes used for connection here are prone to fail

Abstract

The invention provides a winding drum of a winding machine, and relates to a thin strip casting and rolling production line. The winding drum of the winding machine comprises a main shaft, a wedged shaft and multiple fan-shaped plates; the main shaft is provided with a mounting cavity formed in the axial direction of the main shaft; the wedged shaft is arranged in the mounting cavity; the fan-shaped plates are arranged along the axis of the main shaft, and are mounted on the outer wall of the main shaft; the multiple fan-shaped plates are arranged in the peripheral direction of the main shaft; multiple wedged inclined surfaces outwards projected in the radial direction of the wedged shaft are arranged on the wedged shaft; each wedged inclined surface is provided with a plunger module; one ends of the plunger modules butt against the wedged inclined surfaces; the other ends of the plunger modules penetrate through the side wall of the main shaft and butt against the inner walls of the fan-shaped plates; and first overlaying wear resistant layers are arranged in the contact places of the fan-shaped plates and the plunger modules. The winding drum of the winding machine can prolong the total life of the fan-shaped plates to prolong the off time of the fan-shaped plates.

Description

technical field [0001] The invention relates to a thin strip casting and rolling production line, in particular to a coiler, in particular to a coiler reel for thin strip casting and rolling. Background technique [0002] At present, domestic hot rolling coilers mostly adopt the type without internal water cooling, and the coils mainly rely on external cooling water for cooling. In order to ensure that the parts do not fail when coiling at a high temperature of 600-800 ° C, the coiling time is stricter. limits. [0003] In addition, for thin strip casting and rolling with a strip thickness of 0.7-1.91mm, the maximum coil weight of the reel is 32.8t, the maximum coil diameter is 2050mm, and the longest coiling time is about 17min. In order to ensure the normal operation of the reel, the It is necessary to effectively cool the reel, that is, to increase internal water cooling. [0004] The water-cooled wedge plunger reel in the existing hot rolling coiler mainly has the foll...
