Abstract

PURPOSE:To perform vertical positioning of a chock in conformity with a necessary depressing degree, by both restricting the chock from its side by a pressing head driven by an air cylinder or the like and tightening the chock to be restricted in a vertical direction by a jack-driven depressing head and a clamp oppositely arranged to the depressing head. CONSTITUTION: A fixing device, setting a chock pressing head 5, longitudinally driven in the end of a device 4 of air cylinder or the like, in one side of a roll chock 3 of a brush roll 1 while a fixed frame 6 in the other side, drives the device 4 tightening the chock 3 between the device 4 and the frame 6 to be restricted in the horizontal direction. Further the fixing device, arranging a chock depressing head 7 and a chock clamping head 8 in an upper and a bottom side of the chock 3 and vertically driving the depressing head 7 by an actuatot 9 so as to tighten the chock 3 to be redtricted with the clamping head 8 in the vertical direction, forces the brush roll 1 to be brought into pressure contact with a metal strip (a) in an upper or a bottom side of the chock 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roll chock fixing device for brush rolls and puff rolls used for polishing and cleaning of metal strips and the like.

Brush rolls and puff rolls that are used for such processing and processing must be kept in a stable state without vibration during operation to avoid chatter marks being formed on the workpiece or material to be processed. It is essential to be able to efficiently handle and handle new products other than rails.

In order to achieve this, the present inventor previously applied for a patent application filed in 1983-
Completed the technique store of invention No. 281828.

However, the previously proposed invention is limited to restraint by tightening only in the horizontal direction, in which the roll chock of the brush roll is supported by being pressed against the fixed frame from the side by a chock pressing head driven by an air cylinder plunger device. Therefore, when dealing with a new product, the restraint of the worn brush roll can be released more quickly by loosening the chock pressing head with the air cylinder plunger device. It is not possible to easily center the newly brought brush roll in a vertical position with a predetermined degree of reduction.

Therefore, the present invention not only makes it possible to quickly release the restraint during operation and when necessary, but also makes it possible to easily replace the upper and lower flK according to the degree of reduction required for the replaced new brush roll and puff roll. The purpose is to provide a roll chock fixing device for brush rolls, puff rolls, etc. that ensures centering in the seat.

The roll chock fixed back for brush rolls, puff rolls, etc. of the present invention has an air cylinder plunger,
A chock pressing head driven by a roller presses and restrains a roll chock such as a brush roll or puff roll from the side with a fixed frame, and a chock lowering head driven by a jack operated by an actuator such as an electric motor The roll chock is tightly restrained in the vertical direction by a chock clamp head disposed opposite thereto and driven by an air cylinder plunger device.

Central example Embodiments of the present invention will be described below with reference to the drawings.

In the figure, tl+ is a brush roll or puff roll (hereinafter abbreviated as brush roll), +21 is a backup roll that is paired with the brush roll, and in this example, these brush rolls (1) and backup rolls (2) are , Two pairs are arranged before and after the running line of the metal strip (at) so that the required processing or treatment is applied to both the front and back surfaces of the material to be polished or cleaned (hereinafter abbreviated as metal strip) (a). has been done.

An air cylinder plunger i1 is placed on the - side of the roll chock (3) of the brush roll 11). +41
A chock pressing head (5) is attached to the tip of the plunger (4a) and driven by the device (4) in the front and back (left and right in FIG. 1), and a fixed frame 161'x is mounted on the other side. afR and push the chock pressing head (5) to the desired side by the tE movement by the air cylinder plunger device (4), and the BK brush roll 11 between the chock pressing head (5) and the fixed frame 16) ) to apply horizontal restraint by tightening the roll chock (3).

Further, on the upper or lower side of the roll chock (3), there is provided a chock reduction head (7) for pressing the brush roll (1) against the metal strip (a). Place the chock clamp head (81) and place the By-yoke lowering head (7).
is attached to the tip of the rod (10a) of the jack q1 which is driven up and down by an actuator (91) such as an electric motor, and the chock clamp head (8) is attached to the tip of the plunger (lla) of the air cylinder plunger device 011. The brush roll (110 roll chock (3)) is tightly restrained in the vertical direction by the chock lowering head (7) and the chock clamp head (8).

If necessary, a trolley fly with wheels O can be fixed to the roll chock (3) of the brush roll (1).

Achieve your goal by pressing fully.

In the present invention, a chock pressing head driven by an air cylinder plunger device presses and restrains the roll chock of the brush roll from the side against a fixed frame, and the chock is driven by a jack operated by an actuator such as trtP&. The roll chock is restrained vertically by a chock lowering head and a chock pressing head placed opposite to the chock head and driven by an air cylinder plunger device, so that the brush roll does not move in this direction during operation. The roll chock can be reliably restrained from vibrating, and if necessary, by loosening the chock pressing head and/or the chock lowering head, the restraint of the roll chock in the vertical and meridian directions can be quickly released.

In addition, according to the restraining means of the present invention, with the horizontal restraining chock pressing head in a closed state, the vertical restraining yoke pressing head and the chock lowering head can be moved up and down, thereby making it possible to replace them. Add a new brush roll to the top and bottom 5 according to the required degree of reduction.
