Definitions
- the invention relates to a universal roll stand with a divided operator-side Stand, between its upper and lower parting line a vertical stand bracket intervenes.
- Universal stands of this type allow the roller assembly to be changed easily, because e.g. after opening the vertical stand bracket and / or moving away of the operator-side roll stand is the universal roll set for loading and unloading Removal free with the help of a roller change carriage.
- show up problematic here is that between the drive side and the operator side Rolling stand acting in the horizontal and vertical direction with high forces the separation points or joints must be transferred.
- EP A1 0 178 462 it has become known with duo scaffolding, the horizontal forces that occur hydraulically pre-tensioned tie rods to take on and on the roller stand are pivoted out and pivoted in in the rolling direction Immerse open longitudinal recesses.
- the invention has for its object a universal roll stand of the beginning mentioned type so that the high vertical and horizontal forces have it recorded.
- This object is achieved in that in bilateral or lateral stand grooves of the operator-side roll stand one each of the two Parting lines overlapping, the vertical forces between the upper and lower Stand part transmitting transmission element is arranged. While the Horizontal forces as with the well-known Duo scaffolding from the hydraulically pre-stressed Tie rods are taken over, the high vertical forces from the transmission elements subjected to shear and pressure via the joints transferred to the two stand parts.
- a preferred embodiment of the invention provides that the - preferably as Shear blocks trained - transmission elements on the in the stand grooves retractable tie rods are flexibly attached.
- additional actuating cylinders are the tie rods that are required anyway used at the same time to pivot the transmission elements in and out.
- the transmission elements via clamps with play too the tie rods are attached. The clamps create the necessary little air between the tie rods and the transmission elements.
- a universal roll stand 2 anchored in the foundation 1 has a closed one drive-side roll stand 3 and a divided, an upper and a lower part 4a, 4b having operator-side roll stand 4.
- the two stand parts 4a, 4b of the open operator-side roll stand 4 are by a between the upper and the lower parting line 5a, 5b engaging vertical stand bracket 6 with each other connected.
- the one that includes both the horizontal and vertical rollers Roller installation kit 7 is supported with a chock 8 of the vertical rollers 9 a crosshead 10 of the opposite, drive-side roll stand 3.
- the transmission elements 16 are of one such length and arranged on the tie rods 13 that they in the Operating position pivoted position the separation points or joints 5a, 5b of the overlap the open operator-side roll stand 4 upwards or downwards.
- the hydraulically preloaded tie rods 13 take over Horizontal forces, and the transmission elements subjected to shear and pressure or blocks 16 transmit the vertical forces on the upper stand and Lower part 4a or 4b.
- the stand grooves 11 are dimensioned slightly larger (approx. 1 mm) than the transmission elements 16 are wide. To the transmission elements nonetheless 16 fixed in the stand grooves 11 or balanced and thus the Switching off the installation play in the direction of the power flow or rendering it ineffective will the pivoting of the tie rod 13 of the vertical stand bracket 6 with the help of - not shown - roller changing car again applied force to extend.
- the parting lines 5a and 5b both upwards and downwards below overlapping transmission elements or blocks 16 thus ensure that in a universal roll stand that occurs there in the horizontal and vertical directions large forces can be absorbed or transmitted.
