Definitions
- the invention relates to a method and a device for changing roller sets consisting of top rollers, side rollers and a bottom roller and mounted in chocks of a stand of a continuously operating longitudinal seam tube welding machine.
- a large part of pipes made of steel and other metals is produced by continuous longitudinal seam welding.
- a strip is unwound from a coil, formed into a round slot tube in several roll stands and welded.
- For the purpose of joining the strip edges are heated to welding temperature and pressed together in a welding stand so that they weld together.
- the rolls of these stands have to be changed frequently, either with a change in the tube diameter or with advanced wear.
- the time for changing the rollers must be kept as short as possible to avoid unwanted downtimes.
- the roll change should be carried out with little effort in terms of technical and mechanical aids as well as manual handouts.
- the invention has for its object to provide a method and an apparatus with which a roll change can be realized easily and quickly and with little equipment.
- this object is achieved by a method which is characterized by
- an apparatus for performing the method provides
- the top rollers are mounted in guides and can be adjusted by motor
- the removal means of transport is designed as a bridge which overlaps one side a top roller carriage arranged on a guide rail and is arranged on it to be slidable, and engages under the top rollers with a cantilevered arm
- the top roller carriage also the bridge is assigned a displacement device provided outside the welding stand.
- top rollers with their guides are moved into an upper expansion position, for example by means of motor-driven spindle lifting elements.
- the bridge guided on the top roller carriage is moved from the side into the roll stand by means of the displacement device, which can be moved, for example, via a motor / spindle combination, until the bridge engages under the top rollers with its L-shaped arms.
- the bridge is pushed out of the stand by means of the sliding device until it is freely accessible to the side of the stand.
- the top rollers can then be exchanged for another set of rollers.
- a further embodiment of the invention provides for the removal of the top rollers together with the side rollers and the bottom roller that the side rollers are mounted in side roller holders and can be adjusted by motor and the side holders are designed with centering means for the bridge carrying the top rollers.
- the side rollers with their side roller holders are moved apart so far, for example, also by motor-driven spindle lifting elements, until the centerings with the complementary engagement openings of the bridge carrying the top rollers are in cover position.
- the lower roller arranged on a height-adjustable table is then raised.
- the side roller holders are raised over the chocks of the lower roller until the side roller holders sit under the bridge and support it.
- the centering of the side roller holder is now in engagement with the openings in the bridge and locks them in a safe manner.
- the side rollers are uncoupled from their adjusting devices and, on the other hand, the guides are released from the top rollers.
- the entire installation change kit including the bridge with the top rollers placed on it, the side rollers with their holders and the bottom roller, can be pushed out of the stand laterally by a push-out device and completely replaced there with a new roller set.
- Figure 1 shows a general structure of a welding stand of a pipe welding machine in the front view.
- Fig. 3 is a top roller of the welding stand as a partial section of the
- Fig. 7 shows the welding stand of the pipe welding machine with only the top rollers removed, shown in the front view.
- the welding stand 1 shows a welding stand 1 of a pipe welding machine in the longitudinal direction of a pipe 2.
- the welding stand 1 consists of the two top rollers 3, 4, the side rollers 5, 6 and the bottom roller 7.
- the top rollers 3, 4 are mounted in guides 8 and are via a motor-gear combination 9 and a motor-operated spindle lifting element 10 - positions 9 and 10 - employed.
- the side rollers 5, 6 are mounted in side roller holders 11 and are started by a motor-spindle combination 12.
- the lower roller 7 is mounted in chocks 13 which are arranged on a table 15 which can be moved via a height adjustment 14. The entire set of rollers is in the working position according to FIG. 1.
- the upper rollers 3, 4 are moved into an upper removal position by means of the motorized actuators 9, 10. Subsequently, a bridge 16, which is movably clamped on an upper roller carriage 17 (cf. FIG. 3 in this regard), is moved from the side via a spindle-operated displacement device 18 into the position shown below the upper rollers 3, 4.
- the upper rollers 3, 4 with their guides 8 are lowered onto the bridge 16 by means of their motorized positions 9, 10, whereby the upper rollers 3, 4 are supported on the one hand with an overlapping hooking bar 19 on the bridge 16 and on the other hand with their guides 8 rest on an overhanging arm 20 of the bridge 16 which is L-shaped in cross section and provides additional support.
- the bridge 16 and the upper roller carriage 17 are arranged on a mounting rail 21 which is encompassed by the upper roller carriage 17 (cf. FIG. 3).
- the side rollers 5, 6 with their side roller holders 11 are moved apart over the positions 12.
- centerings 22 are arranged on the side brackets 11 with a height distance in the cover position with complementary centering openings 23 of the bridge 16.
- the table 15 is raised with the lower roller 7 via the height adjustment 14 to the level of a scaffolding plate 24.
- the side rollers 5, 6 with their side roller holders 11 are simultaneously lifted from the cantilever arms 25 arranged on the chocks 13 of the lower roller 7.
- the side roller holders 11 are supported under the bridge 16, the centerings 22 engaging in the centering openings 23 of the bridge 16.
- the change carriage 26 can optionally (not shown) be equipped with a prepared new set of rolls, so that after removal of the used set of rolls, for example by a movement to be carried out transversely to the stand 1, the new set of rolls in position for installation into the stand and at the same time the old set of rollers is moved into a position from which, for example, an indoor crane can take over.
- FIG. 7 an expansion of only the upper rollers 3, 4 is shown with reference to FIG. 7, which wear faster compared to the side rollers 5, 6 and the lower roller 7.
- the side rollers 5, 6 and the lower roller 7 do not need to be raised, but rather remain in the working position. Instead, only the top roller carriage 17 carrying the bridge 16 is moved so far on the rail 21 by means of the displacement device 18 that the bridge 16 with the top rollers 3, 4 seated thereon comes into a freely accessible position projecting from the stand 1.
- the top rollers 3, 4 can then simply be exchanged for a new roller set.
