Description

Rolling roll assembly assistance device {ASSEMBLING SUPPORT APPARATUS OF ROLL FOR MILL ROLLING}

The present invention relates to a rolling roll assembly auxiliary device for assisting the assembly of regenerated rolling rolls to the choke smoothly, and more particularly, assembly by performing mechanical operation of keying, washing, or oil lubrication that requires adjustment when assembling roll chalk. The present invention relates to an assembly aid for rolling rolls that is easy to work.

In general, rolling rolls are divided into work rolls and reinforcement rolls. When a work is performed in a rolling stand for a certain period of time, a large amount of wear and scratches are generated on the rolls. After regrinding in a large roll grinder, the rolls are assembled to the chalk again and put into a rolling stand for use.

However, in this process, when assembling the roll to the choke, the key groove in the roll journal and the key attached to the choke are matched with each other, and the assembly is performed by manually rotating the bearing by the operator. Since the work is difficult and the worker is rotated to a certain degree in order to check the match, the work is delayed by checking the position and rotating again, which delays the working time.

In addition, when assembling the reinforcing roll, it is necessary to match the key groove of the roll head with the protrusion inside the hydraulic mechanism used for disassembly and assembly, and the gap between the bearing and the roll journal is very small and there is no lubricating oil so that scratches easily occur inside. Therefore, in order to prevent this, it is necessary to apply the lubricating oil evenly to the roll journal in order to work. The high viscosity of the oil does not spread easily, so that a large amount of oil is applied for a long time to spread evenly. Therefore, a large amount of expensive lubricating oil is applied every time the roll is assembled to the roll choke, which increases the cost and delays the working time.

In addition, the operator removes the carbonized layer and scratches, etc., which are frequently generated in the roll journal part, but the upper side can easily work, but the lower side is difficult to work, there is a problem that the work productivity is lowered.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, and can be safely and easily coated with oil without a waste of expensive lubricating oil and to complete the work in a short time, removing the surface flaw of the roll or It is an object of the present invention to provide a rolling roll assembly aid that is effective in cleaning and can safely perform a keying operation.

Let's move.

Hereinafter, the operation of the rolling roll assembly auxiliary device of the present invention configured as described above.

First, when describing the assembly process of the reinforcement reinforcement roll 11, first, when the lifting jack 37 is operated to lower the lifting skid 32, the roller 33 of the lifting skid 32 is inclined pedestal 31-1. ) To a lower position than the supporting member 31-2, and when the reinforcing reinforcement roll 11 is placed, the roll 11 is placed on the supporting member 31-2, and then the lifting jack ( When the lifting skid 32 is raised by operating 37, the roller 33 comes into contact with the roll 11 and gradually rises. Then, when the hydraulic motor 34 is operated, the roller 33 is rotated by the gear 36 and the roll 11 is also rotated.

The operation as described above is effective to fit the key 14-1 even when assembling the work roll 12 and may help to perform smooth work.

On the other hand, when the operator wants to remove the various carbonized layer and the flaw generated in the journal portion 11-1 of the set reinforcement roll 11 with sand paper, the work is automatically performed by the rotation of the roll if the worker is still in contact with the tool. This is done and can be confirmed with the naked eye.

Protrude outward, and when the extension of the rod 44 is completed, the coupling member 46 installed in the nozzle block 53 is engaged with the coupling member 46 installed in the block guide 41, and a flow path is formed thereafter. When the nozzle 51 is switched to the spray position to match the roll journal 11-1 and the air line 48-2 is opened, the high pressure air washes the roll journal. Thereafter, when the oil line 48-1 is opened, the oil enters the packing 56 and falls, and air from the funnel of the somewhat eccentric packing 56 enters the oil while being rotated at high speed by the eccentric air. It hits the wings of the spray fan 57 and disperses like fog and enters the nozzle 51 and is injected into the roll journal 11-1. The oil forms a thin film and is applied to the roll journal portion.

When the milking of oil is completed, the line 48 is closed and the transfer mechanism 43 is reversed so that the nozzle 51 is inserted into the block guide 41 so that the transfer guide 52 is not disturbed during the subsequent assembly work. .

On the other hand, in the transfer guide 52 when the transfer mechanism 43 advances, the tension spring 60 pulls the nozzle 51 inward, whereby the nozzle 51 forms the same inclination angle as the inclination angle of the roll journal, The compression spring 61 is responsible for adjusting and close the gap according to the movement of the nozzle 51. The elliptical jaws of the movable block 55 and the fixed block 62 move left and right in the elliptical groove of the transfer guide 52 to prevent the nozzle 51 from being parallel to the inclined surface of the Roger 11-1. To achieve.
