Definitions

  • the invention relates to a roll changing device for Roll stands, in particular sextowalt stands, with one Roller change car with a change cassette
  • Running rails for the chocks of the lower work roll and the two intermediate rolls of the Roll set of a sexto roll stand is equipped, the arranged in pairs on top of each other in horizontal planes Rails of the exchangeable cassette when changing the rollers appropriate tracks for the lower work roll and the Intermediate rolls and their chocks in the roll stand correspond and the roller changing carriage with drives for Moving the interchangeable cassette parallel to the roll stand and transverse to the rolling direction and with a device for Pull the work rolls and intermediate rolls out of the Roll stand in the interchangeable cassette and for inserting the rolls from the interchangeable cassette into the rolling stand.
  • the roller changing carriage one from DE 197 47 013 A1 known roller changing device of this type is with four Pliers manipulators for pulling out the two work rolls and the two intermediate rolls from a sexto roll stand into the Exchangeable cassette and for inserting the rollers from the Exchangeable cassette in the roll stand.
  • the upper intermediate roller and the two can be reground Work rolls that together with the roll chocks a sex roll stand was transferred to the removable cassette, removed from the removable cassette with a crane become. Due to the large dimensions of the two chocks the lower intermediate roller extends the space between the Running rails built into the frame of the removable cassette to move the two work rolls and the upper one Intermediate roller not out to remove the lower intermediate roller from the To be able to lift the exchangeable cassette out with a crane.
  • the lower intermediate roller is also available to enable the replacement cassette the two chocks in a separate intermediate frame Interchangeable cassette stored to release the lower one Intermediate roller by a motor drive on the undercarriage the roll changing device parallel to the rolling direction of the the intermediate frame locked with the undercarriage is moved away, to then use the two chocks with a crane from the intermediate frame to highlight.
  • the roll changing device according to the invention stands out through the following advantages:
  • the trolley for pulling out the work rolls and of the intermediate rolls from a sexto roll stand into the Exchangeable cassette and for inserting the rollers from the Interchangeable cassette in the roll stand is with a rotatable Coupling button equipped, which optionally the coupling of the Work rolls and / or the intermediate rolls on the transport car enables.
  • Equipping the exchangeable cassette with running rails for the work rolls and the upper intermediate roll including the roll chocks that come from the shifting area of the rolls can be swung out, allows for roller processing, e.g. for smoothing, lifting the two work rolls and of the two support rollers with a crane upwards from the Interchangeable cassette and lifting the smoothed or new rollers with the crane in the change cassette.
  • the roller changing carriage can be operated individually or by Coupling two cars together in tandem when changing the rollers be used.
  • roller changing device shown in Fig. 1 for Roll stands consist of two coupled roller changing car 1.1.
  • Each roller change carriage 1 has one on the floor Rails on the roll stand can be moved parallel to the rolling direction a Base frame 2 with drive and one on the base frame 2 in Arrow direction b, c traversable transversely to rolling direction a a lifting cylinder 3 driven undercarriage 4 (FIGS. 6 and 11), on which a removable removable cassette 5 is placed.
  • the exchangeable cassette 5 is provided with rails 6,6; 7.7; 8.8 for the chocks 10 - 12 of the lower ones provided with impellers 9 Work roll 13 and the upper and lower intermediate roll 15, 16 of the roller set of a sexto roll stand.
  • Rails 6.6; 7.7; 8.8 of the exchangeable cassette 5 correspond when changing the roller with appropriate tracks for the Work rolls and intermediate rolls and their chocks in Mill stand.
  • Each roller changing carriage 1 is motorized driven, on the rails 6.6 for the two Work rolls 13, 14 and their chocks 10, 17 between two End positions can be moved by the exchangeable cassette 5 Transport carriage 18 for pulling out the two work rolls 13, 14 and the two intermediate rollers 15, 16 together with their Chocks 10 - 12, 17 from a sexto roll stand into the Exchangeable cassette 5 and for inserting the rollers 13-16 with whose chocks 10 - 12, 17 from the removable cassette 5 in the Roll stand equipped (Figs. 2 and 6).
  • Coupling 20 for optionally coupling the work rolls 13, 14 and / or the intermediate rollers 15, 16 when changing the rollers appropriate.
  • the clutch 20 of the transport carriage 18 has one rotatable coupling head 21 with cams 23a, 23b, 24a, 24b, 29, 30, optionally by turning the coupling head 21 corresponding drivers 26, 27; 32, 33 on the chocks 11, 12 of the intermediate rolls 15, 16 and / or the chocks 10, 17 of the work rolls 13, 14 on the roll drive opposite side of the roll stand can be brought into engagement are.
  • the coupling head 21 has two on an outer Turning circle 22 arranged to a certain angle of rotation ⁇ against each other twisted pairs of cams 23, 24, which by two diametrically opposed, spaced on the Rotation axis 25-25 of the coupling head 21 arranged cams 23a, 23a; 23b, 23b; 24a, 24a; 24b, 24b are formed and with diametrically opposite drivers 26, 27 to the Chocks 11, 12 of the intermediate rollers 15, 16 cooperate.
  • the coupling head 21 is on an inner with two others Turning circle 28 diametrically opposed cam 29, 30 provided with a distance 31 to the pairs of cams 23, 24th on the outer turning circle 22 on the axis of rotation 25-25 of the Coupling head 21 are arranged and diametrically oppositely arranged drivers 32, 33 on the Chocks 10, 17 of the work rolls 13, 14 cooperate.
  • the different coupling positions of the coupling head 21 of the trolley 18 are by the Figs. 3a - 3d illustrates, Fig. 3a, the coupling position for coupling the Work rolls 13, 14 and the intermediate rolls 15, 16, Fig. 3b a Intermediate position, Fig. 3c, the coupling position for coupling the Work rolls 13, 14 and Fig. 3d the coupling position of the Coupling head 21 for coupling the intermediate rollers 15, 16 shows.
  • the in the change cassette 5 of a roller change carriage 1 built-in two tracks 6, 6 for the lower work roll 13 and their two chocks 10 and the two Running rails 7, 7 for the upper intermediate roller 15 and their Chocks 11 are by manual swivel drives 37, which consists of a lever linkage 38, a gear 39 and a Hand crank 40 consist of the displacement range of the Work rolls 13, 14 and the intermediate rolls 15, 16 for the Removing the rolls to be smoothed from the exchangeable cassette 5 and the introduction of the ground rolls in the Exchangeable cassette can be swiveled up and away by means of a crane for the roll change in the roll stand back into yours Horizontal position can be swiveled back (FIGS. 4 and 5).
  • Two roller changing carriages 1, 1 are attached to the base frame 2 attached couplings 44 to a tandem car with each other detachable ( Figures 1 and 11).
  • the roll change can faster than with a simple roller change carriage be carried out, because a before the roll change Interchangeable cassette of the tandem car with smoothed or new ones Rollers can be loaded.
