Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding drum of a hot band steel winding machine, and more particularly to an automatic winding drum lubrication device.

Greasing to the winding drum of a conventional hot band steel winding machine is performed through a greasing port such as a grease nipple from the tip of the winding drum or the surface of the winding Tsukioka. In particular, in the winding drum of a hot winding machine that winds high-temperature hot band steel, each location must be individually lubricated because it becomes carbonized due to the surrounding thermal conditions and becomes impossible to lubricate. For this reason, the number of greasing ports (grease nipples, etc.) installed at the tip of the winding cylinder inevitably increases, and greasing is done manually, which takes time and effort and is extremely inefficient. was there. In addition, the winding cylinder can only be lubricated when rolling is stopped, resulting in poor workability and not being able to always provide good greasing, which has the disadvantage of shortening the life of the winding cylinder. Furthermore, the hot band steel winding drum is used under particularly harsh operating conditions among rolling equipment, and its parts are subject to severe wear and tear, making it a device that requires a lot of maintenance. Therefore, disassembly of the winding cylinder,
During replacement work, it is necessary to easily remove the distributing valve and the like placed at the tip of the winder, which poses a problem in that it is necessary to improve workability or shorten the installation and removal time. An object of the present invention is to automatically and smoothly supply the necessary amount of greasing to the necessary parts inside the winding drum even during hot strip winding, thereby improving the service life of the greasing device. To provide an automatic winding cylinder lubrication device that can be easily disassembled and replaced.

The present invention is characterized in that in a winding drum of a winding machine for winding high-temperature hot band steel, a manifold is removably attached to one end of the winding drum. A lubricant supply system that includes a plurality of distribution valves each communicating with a flow path leading to a location where oil is required, and a main pipe to which these distribution valves are connected, and supplies high-pressure lubricant pressurized by a lubricant pump to the main pipe. This automatic winding cylinder lubrication device has a flow path that passes through the main shaft of the winding cylinder in the axial direction as a feed hole.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram of a winding drum of a hot band steel winding machine equipped with an automatic winding drum lubrication device according to the present invention.

Reference numeral 1 indicates a winding drum, and reference numeral 2 designates a manifold (distribution valves arranged on a single sub-plate) according to the present invention, which is attached to the tip of the winding drum. The winding lug 1 has a structure in which the rotating cylinder 3 performs an expansion and contraction action to extract the wound steel strip. The rotating cylinder 3 is a rotating joint 4
It is operated by pressure oil supplied from Therefore, the manifold 2 is 4mm larger than the diameter of the winding drum 1 in order to extract the coil.
It is placed inside the flea and performs automatic lubrication. Reference numeral 5 denotes a refueling pump, which supplies lubricant at high pressure to a distribution valve 9 (to be described later) in order to distribute lubricant to the inside of the winder 1 through a rotary joint 4. Oil and fat are fed to the manifold 2 through a oil and fat feed hole 7 provided in the main shaft 6 of the manifold 2 and penetrating to the tip.

FIG. 2 is an enlarged view of the manifold 2 seen from the tip side.

Reference numeral 8 designates a sub-plate serving as a base plate of the manifold 2, which has a circular shape and can be removably fixed to the tip of the winding 8 with a mounting bolt 9.

Reference numeral 10 denotes distribution valves which are symmetrically arranged on the sub-plate 8 at intervals of 450 degrees. A main pipe 11 sequentially connects the distribution valves 10 arranged on the sub-plate, and has one end connected to the oil supply hole 7 to supply oil to each distribution valve. Reference numeral 12 denotes a greasing port leading to a greasing point inside the winding drum 1, through which the winding drum 1 is fed from the distribution valve 10.
Oil and fat are supplied to the inside of the FIG. 3 is a concrete diagram of the locations to be supplied with grease from the greasing port 12 shown in FIG. 2.

Oil and fat are sequentially fed to each distribution valve through the main pipe 11, and are supplied to a predetermined location via each distribution valve. FIG. 4 shows the joint surface of the winding drum 1 and the supply plate 8, and the oil and fat supplied from the distribution valve 1 passes through the greasing hole 13 and is supplied into the winding Tsukioka 1. The mating surfaces of the winding cylinder and the sub-plate 7 are sealed by a ring 14. Since the present invention is configured as described above, the oil and fat under pressure by the greasing pump 5 passes through the oil and fat feed hole 7 provided in the main shaft 6 of the winding drum 1 via the rotary joint 4. , manifold 2
It is fed to the main pipe 11 above.

The fed oil and fat are distributed to predetermined locations inside the winding drum 1 through a distribution valve 10 connected to a main pipe 11.
Therefore, the inside of the winding drum can be automatically and smoothly refilled even during winding of the hot band steel.

In addition, since the manifold has a structure that can be easily attached to and removed from the winding cylinder, it is possible to improve the replacement work efficiency and shorten the time when disassembling and inspecting the winding cylinder. Furthermore, since lubrication can be performed whenever lubrication is required, it is possible to extend the life span of the winding unit. As is clear from the above description, according to the present invention, there is provided a sub-plate that can be easily attached and detached to the same tip of the winding 8, a plurality of distribution valves are arranged on the sub-plate, and the distribution valves are connected to the main pipe. By adopting a configuration in which oil and fat supply holes are provided on the same main shaft of the winding 8 to feed oil and fat under pressure by a greasing pump to the main pipe, the hot strip winding Among these features is an automatic winding drum that automatically and smoothly supplies the required amount of greasing to the necessary locations inside the winding drum, thereby extending its life and making it easy to disassemble and replace the greasing device. A greasing device can be provided.
