Description
Technical Field
The invention belongs to the technical field of metal rolling equipment, and particularly relates to a quadrangular pyramid type winding drum fixed cone shaft head device which is simple in structure, safe, stable and simple and convenient to operate.
Background
To maintain the stability and efficiency of the rolling process, the coil is wound more tightly and the rolled piece is given the correct orientation as it is fed into and out of the roll. In the rolling process in which a hot-rolled or cold-rolled steel material is wound in a roll shape, it is generally necessary to maintain a front tension and a rear tension, and therefore an uncoiler and/or a coiler with a collapsible roll are provided. The recoilers with tension reels are installed both before and after the single stand reversible cold rolling mill, while the recoilers are arranged after the finishing stands on hot strip tandem mills (hot tandem rolling trains), cold strip tandem mills and wire mills, so that they are used more frequently in the sheet rolling process.
After the rolling of the coiler is finished, the steel coil is unloaded from the winding drum, so the winding drum of the coiler must be made into a single cantilever type collapsible winding drum. The winding drum mainly comprises a pyramid shaft, a fan-shaped plate and other mechanisms, and the pyramid shaft is axially pulled by an oil cylinder to enable the fan-shaped plate to axially move so as to realize expansion and contraction. The coiling drum of the coiling machine establishes tension through the expansion and contraction of the coiling diameter, and the tension can reduce the pressure acting on the roller during rolling, reduce the warping phenomenon of the strip steel and be beneficial to improving the surface quality of the strip steel. However, the reel is used to wind the strip under great tension, so that the reel shaft is subjected to great loads (including the weight of the reel, the weight of the coil of strip, the moment caused by bending the strip and the tension, etc.). In order to ensure the rigidity and strength of the reel shaft and reduce the bending of the reel shaft, besides increasing the size of the reel shaft, a movable support capable of rotating is generally arranged at the free end of the reel. At present, for the situation that the coil weight is relatively heavy, although the recoiling machine is provided with a movable support (as shown in fig. 1), the spindle head structure at the free end of the winding drum is that a conical spindle head follows the spindle head, but because secondary expansion and contraction are sometimes required, the spindle head of the winding drum follows the spindle head in the winding drum to generate secondary displacement motion again, two positions exist before and after primary expansion and contraction and secondary expansion and contraction, the spindle head of the winding drum cannot be positioned twice by the existing movable support, so that the spindle head cannot be stably supported, the coil is too heavy, the head is heavy, the tail is light, and the service life of the winding drum and the stability and the precision of a rolled strip are influenced. In the prior art, the existing movable supporting structure is replaced by a roller type support and the like, but for a large-coil-weight coil, the roller type support is safer and more reliable without a device for directly holding the shaft head of a winding drum; of course, the outer surface of the shaft head device is changed into a flat shaft from a conical shaft, but relative displacement can be generated, the winding drum shaft head is not really tightly held, and the safety is also deficient.
Therefore, the design and development of a fixed shaft head device which is safe, reliable, simple and convenient to operate and suitable for a secondary expansion and contraction winding drum is urgent.

In addition, the invention also arranges a wear-resistant shaft sleeve with simple structure between the inner sleeve of the riding wheel and the shaft head, so that the shaft head can not passively rotate in the movably supported inner sleeve when the expansion and contraction oil cylinder drives the pyramid shaft to rotate, thereby effectively reducing the wear of the inner sleeve of the riding wheel with complex structure, and further improving the service life and the precision of the whole device.
Therefore, the invention has the characteristics of simple structure, safety, stability and simple and convenient operation.
