Definitions

  • the invention relates to a system consisting of at least one roll stand and at least one roll changing device, wherein in the roll stand at least two rolls are arranged vertically one above the other, which define a nip between them, wherein each roll consists of a working part and two journals, wherein the bearing journals in bearing arrangements in Roller stands are mounted and wherein between the working part and the bearing pin clutches are arranged, with which the working part can be decoupled from the bearing pin.
  • Such a system is out of the EP 1 790 423 B1 known.
  • a roll stand is shown, which can be equipped with two rollers.
  • the rollers are constructed so that the working part of the rollers can be separated from the roll neck.
  • couplings between the working part of the roller and the journal are available. This has the advantage that the roll neck can remain in their bearings in the roll stand for roll change and only the working parts of the rolls must be changed.
  • the clutches are released and removed the workpieces from the roll stand.
  • the previously known solution provides that the roll located in the upper of the roll stand has a greater clear width between the couplings, while the clear width between the couplings for the lower roll is smaller. This facilitates the removal of the two working parts of the rollers by lifting upwards, for example by means of a roll changing device in the form of a crane.
  • the invention is therefore based on the object , a system of the type mentioned - consisting of roll stand and roll changing device - educate so that changing the working parts of the rollers faster and easier with yet great precision is possible.
  • the roll changing device comprises a support member which is formed for a horizontal insertion into the roll stand and one of the number of rollers corresponding number of receiving spaces for the working parts of the rollers, wherein on the one hand the support member and on the other hand, the roll stand Guide means is provided, wherein the guide means of the support element engage positively in the trained for a guided horizontal and vertical movement during roll change guide means of the roll stand.
  • a preferred embodiment of the invention provides sliding blocks as guide elements of the support element and guide slots with horizontal and vertical sections as guide elements of the roll stand.
  • the roll changing system according to the invention is therefore particularly suitable for a roll stand designed as a stretching roll stand or as a cross roll stand.
  • the carrier element is preferably connected to means for translational movement of the carrier element in the horizontal direction or can be brought into connection with such means. Accordingly, it is preferably provided that the carrier element is connected to means for translational movement of the carrier element in the vertical direction in connection or can be brought into connection; a means for translational movement of the carrier element in the vertical direction can be in particular a crane.
  • the support member may consist of at least two substantially identical plates which are mutually parallel and offset in the direction of the axis of the rollers connected to each other.
  • the plates are preferably made of a flat sheet.
  • the roll changing device may optionally be used, for example, a change carriage or a removable crane.
  • a roll stand 2 of a stretching roll stand is shown.
  • two rollers 4 and 5 are installed, in the vertical direction V one above the other.
  • the rollers extend in an axial direction a. They are not made in one piece, but are composed of a working part 6, 7 and two laterally thereto arranged bearing pin 8, 9.
  • the working parts 6, 7 of the rollers 4, 5 and the bearing pins 8, 9 can be coupled or decoupled by means of couplings 12.
  • This construction concept is known per se and has the advantage that the bearing pins 8, 9 of the rollers 4, 5 can remain in their bearing arrangements 10, 11, with which they are mounted in the roll stand 2, even if the working parts 6, 7 of the rollers. 4 , 5 need to be changed.
  • the roll changing device 3 consists in the present case of two flat plates 20, which in the FIGS. 2 to 6 sketched shape and at a distance - as seen in the direction of the axis a - are firmly connected.
  • the plates are formed so that they form two receiving places 14, 15 for the two working parts 6, 7 of the rollers 4, 15, which are designed like a fork, so that the working parts 6, 7 can rest safely in the receiving places 14, 15.
  • the receiving sites 14, 15 have for this purpose bearing surfaces 16, 17 which are adapted to the shape of the working parts 6, 7, ie the bearing surfaces 16, 17 have a circular arc-like shape - seen in the direction of the axis a.
  • the roll changing device 3 further comprises means 18 for horizontal displacement and means 19 for vertical displacement, which in Fig. 2 are indicated schematically.
  • the roll changing device 3 can thus be moved translationally in the horizontal direction H and in the vertical direction V.
  • the means 18, 19 can also be realized by a crane, which moves the roll changing device 3 as such.
  • the roll stand 2 together with roll changing device 3 forms a system 1 with which a simple roll change or change of the working parts of the rolls is possible.
  • guide means 21, 22, 23, 24 are provided (s. Fig. 2 ), which ensure the precise guidance of the roll changing device 3 in the roll stand 2.
  • the guide means consist of guide slots 21 and 22, which are incorporated in the roll stand 2, and of sliding blocks 23 and 24, which are arranged on the roll changing device 3 (in each case in two planes in the axial end regions of the tool changing device 3).
  • Fig. 5 is the roll changing device 3 arrived in the uppermost position, ie the sliding blocks 23, 24 are at the upper end of the vertical sections 27, 28 of the guide slot 21, 22 arrived. Now, the roll changing device 3 along the horizontal portions 29, 30 of the guide slot 21, 22 in the horizontal direction from the roll stand 2 are moved out again, now the workpieces 6, 7 of the rollers 4, 5 rest in the receiving stations 14, 15.
