The present invention relates to a choke separating / coupling device of a rolling roll, and more particularly, when the choke coupled to both sides of the rolling roll is separated or when the rolling roll is seated on a support to couple the chokes to both sides of the rolling roll. The present invention relates to a choke separating / coupling device of a rolled roll capable of quickly performing a choke separating / combining operation by minimizing impact and precisely matching a center of choke.

In general, in the cold rolling process for producing cold rolled products, a plurality of rolling rolls are used, and the rolling rolls roll a product while continuously rotating, thereby generating a fatigue layer on the surface.

Since the fatigue layer acts as a cause of causing surface defects of the cold rolled product, in order to remove the fatigue layer generated on the surface of the rolling roll, the rolling rock is periodically or frequently replaced. Separation and joining of the combined chokes should be carried out.

Since the choke separation / joining operation needs to coincide with the center for stable rotation of the rolled roll, there is an urgent need for a device capable of quickly and simultaneously matching the choke separation / joining operation.

In the related art, as shown in FIG. 1, the rolling roll 2 is separated from the cold rolling mill and seated on the seat 1.

When separating the chokes 3 on both sides of the rolling roll 2 seated on the seat 1, the wires 4 are fastened to the chokes 3 for the purpose of the hooking operation. While moving the wire 4 by using to separate the choke (3) caught on the wire (4).

In this way, the rolling roll 2 having the separation of the choke 3 is completed is moved to remove the fatigue layer generated on the surface.

And the rolling roll (2) is the removal of the fatigue layer of the surface is seated on the seating table (1) in order to couple the choke (3) on both sides and the choke (3) in the reverse order to separate the choke (3) To combine.

However, when separating the choke (3) using the wire (4) in this way, when the rolling roll (2) combined with the choke (3) in the upper center of gravity is seated on the seating table (1) Since the choke (3) is rotated by the impact force generated when the rolling roll (2) is in contact with the seating table (1) because it is impossible to adjust, damage caused by interference with surrounding equipment, as well as a serious accident may occur. In order to separate the choke (3), the choke (3) must be rotated in the initial direction (toward the center of gravity upwards), there was a problem that excessive work time is required.

And when the choke (3) is combined to use a moving device that can not be fine-adjusted, it takes too much time to match the center of the rolling roll (2) in a timely supply of the product due to the pause of the rolling equipment There was a problem that the productivity is reduced.

The present invention has been invented to solve the above problems, the object is to prevent the rotation according to the center of gravity during the disassembly operation of the choke coupled to both sides of the cold rolling roll and to prevent the shaking during the coupling operation to the center of the rolling roll and choke The present invention provides a choke separating and joining device for a rolled roll that can quickly perform a coincidence operation and prevent choke breakage and work time delay.

After supporting the side of the choke 3, the front and rear support arms 42 are preferably rotated to support the front and rear of the choke 3.

Because the choke 3 is to be corrected by the position correction means 30 after the choke 3 is seated on the choke seating plate 20, the choke 3 is moved back and forth so that the correction work can be smoothly performed. To do this.

Therefore, the side support arm 41 is installed higher than the front and rear support arms 42 so that the front and rear support arms 42 are rotated after the side support arms 41 supporting the sides of the choke 3 are rotated. do.

In addition, the support plate 43 is installed inside the side support arm 41 and the front and rear support arms 42, and an idle roll rotated in contact with the choke 3 inside the support plate 43. 44 is installed and the support plate 43 is elastically installed as a shock absorbing spring 45 to cushion the vibration generated in the side support arm 41 and the front and rear support arms 42.

When described in detail with reference to the accompanying drawings showing an operating state of the present invention configured as described above.

First, the state of separating the choke (3) coupled to both sides of the rolling roll (2) is as follows.

Before the rolling roll 2 is seated on the seating table 1, the choke separating and coupling device of the present invention is placed on both sides of the seating table 1.

In this case, when the cylinder 12 of the moving means 10 is operated, the moving base 13 installed in the moving cylinder 12 is moved while being guided by the guide rails 11 and the moving base 13 is rolled on the roll. The cylinder 12 is stopped when located directly below the choke 3 provided on both sides of (2).

In this state, the rolling roll 2 is seated on the seating table 1 by the hook work, and the choke 3 coupled to the rolling roll 2 is seated on the upper surface of the choke seating plate 20.

When the choke 3 is seated on the choke seating plate 20, the choke seating plate 20 moves downward while pressing the side support shaft 22 and the front / rear support shaft 23, and each support shaft is a spring ( 21 is lowered while compressing, and since the side support arms 41 are installed higher than the front and rear support arms 42, the lower support plates 41 are formed on the upper side of the side support shafts 22 ( 22a) is first contacted and the side support arm 41 is rotated first.

When the side support arm 41 is rotated, the upper end thereof is in close contact with the side of the choke 3 to prevent the left and right flow of the choke (3).                     

At this time, the choke detection sensor 25 installed on the top surface of the choke seating plate 20 detects the presence of choke.

That is, when the choke 3 is detected on any one side of the choke sensor 25, the choke 3 is moved to one side, so that the choke 3 is moved to the center.

Therefore, when the driving motor 31 installed on the choke seating plate 20 is operated and the rotating shaft 32 is rotated, the driving gear 33 formed on the rotating shaft 32 and the driven gear geared to the driving gear 33 ( Since the 35 is rotated together, the rotating roll 34 having the driven gear 35 is rotated to move the choke 3 seated on the choke seating plate 20.

If the choke 3 is moved and the choke 3 is not detected by the choke sensor 25, the choke 3 is in a state located at the center.

In this way, if the choke 3 is aligned in the center and the choke 3 is further lowered, the support shaft is further lowered by the load of the choke 3 and the lower plate formed on the front and rear support shafts 23. When 23a presses the front / rear support arm 42, the front / rear support arm 42 pivots around the hinge to support the front / rear of the choke 3 to prevent the choke 3 from flowing. Will be done.

On the other hand, the support plate 43 for supporting the idle roll 44 in contact with both sides of the choke (3) is elastically installed with a buffer spring 45, so that the front and rear of the choke (3) to support When the rear support arm 42 is rotated, even if the side support arm 41 is rotated, the shock absorbing spring 45 is compressed by the rotation distance.                     

As described above, when the choke 3 is aligned and fixed, the choke 3 is separated from the rolling roll 2. In this case, when the cylinder 12 installed in the moving means 10 is operated in the reverse direction, the cylinder As the moving base 13 provided in (12) moves, the choke 3 seated on the choke seating plate 20 moves together and is separated from the rolling roll 2.

When the choke 3 is seated on the choke seating plate 20 and the weight of the choke 3 is eccentric to one side, the choke seating plate 20 cannot be leveled, and at this time, the moving base 13 Is rotated to one side.

This is because the pivoting needle 52 of the horizontal check unit 50 installed on the front of the movable base 13 is not positioned at the center of the support plate 51. When the weight deviation is large, the support plate 51 Installed sensor 53 is to detect the rotation needle (52).

When the rotary needle 52 detects the sensor 53 as described above, the air is injected into the air tube 14 on the side of the air tube 14 installed in the lower portion of the moving base 13 or the lifting cylinder 15. ) To keep the moving base 13 level.

On the other hand, the process of combining the choke (3) on both sides of the rolling roll (2) will be omitted because the above process is to be performed in the reverse order.

Therefore, the present invention is to be able to quickly and easily perform the separation and bonding of the choke (3) on both sides of the rolling roll (2).

 The present invention minimizes the impact force generated when the rolling roll is seated on the seating board to prevent breakage due to the impact, and accurately chokes the centering operation during the separation and coupling of the choke coupled to both sides of the rolling roll. There is a unique effect that can prevent the malfunction and damage due to the eccentric coupling.
