Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a holder for at least one guiding beam with a rolling material guide of a grooved roll rolling mill, which beam in the working position is located on the @plate. It relates to a type that is fixed to a disposed roll stand and can be pivoted away from the roll stand when the roll is removed.

Several proposals are already known which deal with the problem of exchange and positioning of 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. The construction principle of the easily replaceable holder for the guide beam, known from DE 15 27 756 A1, is such that the beam, together with its frame, can be easily removed and the roll stand can be opened at the top. It is possible to fix it to the roll stand by inserting it into a shaped pivot bearing and by a mating and closing operation. With this known holder, a new guiding beam with a pre-prepared rolling stock guide can be installed in the quickest possible manner during a groove change, so that the rolling stock can be placed on the beam in the quickest possible manner. Time-consuming sliding work of the guide becomes unnecessary. However, the disadvantages of this known construction are that the roll change time is adversely affected by the need for a crane to attach and remove the holder from the roll stand, and, in addition, the swivel bearing is arranged on the roll stand. This makes it necessary to set the height position of the guide beam in such a way that the device in question is aligned with the exact rolling position of the lower roll.

Starting from the above-mentioned known guide beam holder, the object of the present invention is to be able to easily move away and turn for roll exchange;
Moreover, it is an object of the present invention to provide a guide beam holder that does not require sliding of the rolled material guide on the guide beam and can be easily adapted to different height positions of the lower rolls.

According to the invention, this object is achieved in that the holder consists of at least two arms pivotable about a vertical axis, the free end of the first pivoting arm having a 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 solved by being pivotably mounted on the bottom plate.

According to this embodiment of the invention, the guide beam can be easily pivoted away from the area of the grooved roll together with the rolling stock guide, thereby making it possible to remove the grooved roll. 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 for sliding the rolling material guide along the guide beam when adjusting the different hole shapes.

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.

Adjusting the height of the guide beam or rolling material guide to adapt it to different height positions of the lower roll reduces the necessary height difference, which is not practically large, from the height of the beam. This is possible by compensating by adjusting the position.

The height position of the guide beam can be changed by adjusting the deviation according to the first embodiment of the present invention. It is also conceivable, for example, to use a wedge-shaped adjustment mechanism.

If it is necessary to use a large and heavily designed guide beam or multiple guide beams, another embodiment of the invention provides two symmetrical holders by which the roll The guide beam should be held on both sides of the machine (.) This configuration ensures stable guidance of the guide beam during separation and turning.

The present invention is based on the premise that the guide beam is rotated on the holder by a worker, but the moving crab unit is applied to one of the rotation arms or the guide beam to perform the detachment rotation. Mechanization is also possible within the scope of the invention.

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

A roll stand or a plurality of slotted rolls 2 as shown in FIG. 1 is supported. 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. In the working state, this guide beam 5 is mounted on the roll stand 1, ie screwed into its elongated hole 6 by means of a schematically illustrated fixing screw 7. The holder of the guide beam 5 consists of arms 11 and 12 which are pivotable about vertical axes 8 and 9, of which a support member 14 is attached to the bottom plate 13 of the swing arm 12 and the stand 1. through the vertical axis 8
It is supported so that it can pivot around the center. The swivel arm 11 is supported in a 5T rotatable manner around an axis 9 perpendicular to the free end of the swivel arm 12, and is further supported around an axis 10 perpendicular to the free end of the swivel arm 11. A beam 5 is pivotably supported.

In order to adjust the height of the guide beam 5 with respect to the swing arm 11, a VCA joint screw 15 is provided, and this adjustment screw allows the guide beam 5 to be adapted to the position of the lower hole-shaped roll 2. I am forced to do it. As can be further seen from the side view of FIG. 2, the rolled material guide 4 can be arranged in the dovetail groove 1G of the guide beam 5 so as to be fixed therein by being tightened by the member 171C. and
This fixed arrangement allows the pivoting mechanism of the pivoting arms 11 and 12 to be combined with the pivotability of the guide beam 5 to enable the pivoting of the guide beam 5 towards and away from the roll screen 1-1. This is possible because one-law square sliding on the first factor surface is possible. In this case, the elongated hole 6 allows the guide beam to be fastened to the roll stand 1 within the length of the elongated hole. Furthermore, in FIG. 6, the guide beam 5 is attached to the fixing screw 7.
The positions of the swing arms 11 and 12 when screwed onto the roll stand 1 are shown.

The partial view of FIG. 4 shows a simple example of the structure of the guide beam 5σ) height adjustment mechanism for the pivot arm 11. The adjustment screw 15 is inserted into the threaded hole 18 of the guide beam 5.
It is guided through the swivel arm 11 and is supported on a pin 19 which is arranged vertically and immovably in the pivot arm 11. This pin 19 engages in a hole in the guide beam 5 or in the bush 20. In response to adjustment of the adjustment screw 15, the guide beam 5 and the bush 20 slide in the yoke direction. Te pin 19
This allows the distance between the id beam 5 and the pivot arm 11 to be adjusted. The corresponding nut 21 serves for fixing the guide beam 5 in the desired adjustment position.

According to the holder according to the present invention, after the guide beam 5 is released from being fixed to the roll stand 1 by the fixing screw γ,
A pivoting of the guiding beam 5 with the rolling material guide 4 away is possible in a simple manner, so that the guiding beam 5 can be pivoted out of the range of the hand-shaped roll 2. In this case, each of the swing bearings between the zero rate 13 and the swing arm 12, between the swing arm 12 and the swing arm 11, and between the swing arm 11 and the guide beam 5 are arranged in respective predetermined vertical directions. It moves about the axes 8, 9 and 10 of. Each of the above-mentioned parts is independently pivotable so that it can be guided into any desired relative position with respect to the guide beam 5 or the roll stand 1 within the longitudinal length of the respective pivot arm. Naturally, the pivoting movement of the guiding beam 5 may also be mechanized by one of the beams or each pivoting arm (acting piston-cylinder unit).
