Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides support for at least one guiding beam of a groove roll rolling mill with a rolling material guide, the guiding beam being arranged on a bottom plate in the working position. The present invention relates to a support mechanism that is fixed to a roll stand, and that can be pivoted away from the roll stand when the roll is removed.

Several proposals are already known which deal with the problem of replacing and positioning rolling stock guides in groove roll rolling mills of the type mentioned above. In most cases, when changing the rolls, it is also necessary to change the rolling stock guides that are attached to them or to slide them on the guide beams. Federal Republic of Germany Patent Application Publication No. 1527756
From the specification, an easily exchangeable support arrangement for a guide beam is already known, in which the frame of the guide beam can be easily inserted into an upper open pivot bearing provided on the roll stand. It is adapted to be removably fitted into the roll stand, and then pivoted to come into contact with the roll stand and fixed to the roll stand. In this case, when replacing the hole pattern, a new guide beam equipped with a rolled material guide prepared in advance is installed. Therefore, the disadvantage of the known support mechanism is that a crane is required to attach and remove the support mechanism from the roll stand, which results in long roll change times, and furthermore, due to the location of the swivel bearing on the roll stand, The height position of the guide beam is defined and the support mechanism must therefore be set to the exact rolling adjustment position of the lower roll.

Starting from the above-mentioned known support mechanism for a guide beam, an object of the present invention is that it can be easily moved away and swiveled for roll change, and that there is no need to slide the rolled material guide on the guide beam. Furthermore, it is an object of the present invention to provide a support mechanism for a guide beam that is easily adaptable to different height positions of the lower roll.

According to the invention, this object is achieved in that the support mechanism consists of at least two pivoting arms pivotable about a vertical axis, the free end of the first pivoting arm being provided with a vertical axis. A guide beam is carried which is pivotable about a vertical axis, and at its other end is supported the free end of a second pivot arm, which itself can pivot about a vertical axis. This is achieved by being pivotably mounted on the bottom plate.

According to this embodiment of the invention, the guide beam together with the rolling material guide can be easily pivoted away from the area of the grooved roll, so that the grooved roll can be removed. In this case, each rolling stock guide remains non-slidably attached to the guide beam and is nevertheless movable parallel to the roll axis due to the arrangement of the pivot arm. This not only shortens the roll change time, but also eliminates the need to slide the rolling material guide along the guide beam when adjusting to another hole shape.

According to one embodiment of the invention, a member for changing the relative height position of the first pivot arm and the guide beam supported on the pivot arm is disposed. It is advantageous to have one.

Changing the height position of the guide beam is one of the aspects of the present invention.
According to an embodiment, this can be done by means of an adjusting screw.
It is also conceivable, for example, to use a wedge-shaped adjustment mechanism.

The present invention is based on the premise that the guide beam is pivoted on the support mechanism by a worker, but the detachment pivot is performed by applying a power unit to one of the pivot arms or the guide beam. It is also possible within the scope of the invention to mechanize.

The invention will now be explained with reference to the illustrated embodiment.

A plurality of grooved rolls 2 are supported on a roll stand 1 shown in FIG. Each rolling stock guide 4 for inserting the rolling stock into each slot 3 of the slotted roll 2 is attached to a guide beam 5. This guide beam 5 is attached to the roll stand 1 in the working state, i.e. its elongated hole 6
It is screwed on by a fixing screw 7, which is schematically shown inside. The support mechanism for the guide beam 5 is a pivot arm 11 that can pivot about vertical axes 8 and 9.
and 12, of which the swing arm 12 is attached to a support member 14 on the bottom plate 13 of the roll stand 1.
It is supported so as to be pivotable about a vertical axis 8. The pivoting arm 11 is supported so as to be pivotable about an axis 9 perpendicular to the free end of the pivoting arm 12, and furthermore, the free end of the pivoting arm 11 is supported for guiding around an axis 10 perpendicular to the free end of the pivoting arm 12. A beam 5 is pivotably supported.

An adjustment screw 15 is provided for adjusting the height of the guide beam 5 relative to the pivoting arm 11, by means of which the guide beam 5 is adapted to the position of the lower grooved roll 2. I am forced to do it.
As can be further seen from the side view in FIG. 2, the rolled material guide 4 can be arranged in the dovetail groove 16 of the guide beam 5 so as to be clamped by a clamping member 17 and to remain non-slidably fixed there. This fixed arrangement allows the pivoting mechanism of the swing arms 11 and 12 to be coupled with the pivotability of the guide beam 5, thereby allowing the guide beam 5 to approach and move away from the roll stand 1. This is possible because the beam 5 is allowed to slide laterally on the plane of FIG. In this case, the elongated hole 6 allows the guide beam to be screwed to the roll stand 1 within the length of the elongated hole. Furthermore, FIG. 3 shows the position of the pivot arms 11 and 12 when the guide beam 5 is screwed onto the roll stand 1 by means of the fixing screw 7.

The partial view of FIG. 4 shows a simple example of the structure of the height adjustment mechanism of the guide beam 5 with respect to the pivot arm 11. As shown in FIG. The adjustment screw 15 is the guide beam 5
is guided through the threaded bore 1 of the swivel arm 11 and is supported on a pin 19 arranged vertically and immovably in the pivot arm 11. This pin 19 engages in a hole or bushing 20 in the guide beam 5. Depending on the adjustment of the adjusting screw 15, the guide beam 5 slides against the pin 19 via the axial sliding movement of the bushing 20, thereby adjusting the distance between the guide beam 5 and the pivot arm 11. It's becoming possible. The corresponding nut 21 serves for fixing the guide beam 5 in the desired adjustment position.

According to the support mechanism according to the present invention, after the fixation of the guide beam 5 to the roll stand 1 by the fixing screw 7 is released, the guide beam 5 having the rolled material guide 4 can be easily moved away and turned; As a result, the guide beam 5 can be manually moved out of the range of the slotted roll 2 and swiveled. In this case between the bottom plate 13 and the pivot arm 12 and the pivot arm 1
Each pivot bearing between pivot arm 2 and pivot arm 11 and between pivot arm 11 and guide beam 5 moves about a respective predetermined vertical axis 8, 9 and 10. The guiding beam 5 can be rotated independently of each other by allowing each of the above-mentioned parts to rotate independently.
Within the longitudinal extent of the respective swivel arm, it is possible to guide it into any desired relative position with respect to the roll stand 1. Naturally, the pivoting movement of the guide beam 5 may also be mechanized by a piston-cylinder unit acting on the beam or on one of the respective pivot arms.
