- the driving force is transmitted by means of a horizontally arranged, continuous and rotatably mounted drive shaft and beveled on both sides bevel gear stages on the two opposite the vertical at an acute angle inclined propeller shafts, which in turn their rotational movement in Transfer cardan shaft transducers via cardan shaft heads to the edger rollers.
- the known compression roll mill has the disadvantage that it occupies a large space.
- An advantage of the invention is that the compression rollers and the associated gear are resolved into separate units.
- Another advantage of this new embodiment is that the rotational movement is transmitted directly from the transmission gears connected via a synchronous shaft to a single drive motor or from the transmission gears driven by a respective drive motor to the drive shafts. Therefore, these can be arranged at an acute angle to the horizontal.
- the overall height attributable to the propeller shafts that are inclined relative to the vertical can be dispensed with, and the construction according to the invention of the compression mill permits a more compact construction compared with the prior art.
- the rotary drive comprises two drive motors, each of which, in particular via a transmission gear, is connected to one of the two drive shafts.
- the two propeller shafts are each connected to gears and that the belonging to one of the propeller shaft transmission is connected via a synchronous shaft with the drive motor for the common drive of the two gearboxes.
- the two propeller shafts are via a common transmission and connected to this subsequent synchronous shaft with the drive motor.
- the gearboxes are designed, for example, as a transmission gearbox and, for example, as a combed roller gearbox.
- the synchronous shaft is mounted in a guide element, by which it is supported relative to the ground.
- the rotary drive is arranged below the hut floor level.
- a media chain is mounted, which is connected to the arranged between the propeller shafts and the compression rollers gears and to supply the transmission with the necessary media for operation, in particular with a lubricant or a coolant, and with electrical voltage, in particular for measuring instruments, is used.
- the compression roll comprises a roll stand with two transverse heads and a plurality of bars arranged between them.
- the crossheads each take Walzenanstell insightfulen, each acting on one of the two compression rollers.
- the crossheads each have at least one balancing cylinder for pretensioning the rolling device and for carrying out movements when changing the rolls.
- tracks are arranged on the rails for the management of Balanciertraversen, the compression rollers and the transmission.
- a further advantage consists in that roll journals directed downwards are arranged on the edging rolls and which are connected via positive locking to a roll neck. zen Economicser are connected in the associated gear.
- the compression roll mill consists for example of a roll stand with two transverse heads or traverses and two upper, two middle and two lower bars.
- the QuerPSupter take at least ever a Walzenanstell Surprise, which operates mechanically, hydraulically or consists of a combination of both modes of operation.
- the Walzenanstellinnate acts on the two compression rollers and exerts the rolling force required to compress the lateral edges of a metal strand.
- the two crossheads at least each take a Balancierzylinder on which a balance, d. H. a virtually backlash-free clamping of the roller device, performs.
- the crossheads are connected by the spars, which absorb forces from the rolling process in all three spatial directions.
- tracks are arranged on the upper and lower spars, which guide the Balanciertraverse, the compression rollers and the associated gear.
- the raceways may be inclined for certain applications.
- the Balancierzylinder and the Walzenanstell Marie may be arranged inclined to achieve the optimum power position and for the motion transmission.
- the balance crossbar is connected to the balance cylinder. She is led here on careers on the upper spars and positively connected to the compression roller set. During the compression roll change, the balancing cross members and the gear units remain in the compression roll mill.
- the compression roller set is pressed by the roller adjustment to the rolling stock and exerts the rolling force.
- the compression roller is equipped with a downwardly directed roll neck, which is positively connected to a roller hit in the transmission and thus the torque from the transmission transfers to the roller.
- the positive connection is formed by a roller-side flat pin and corresponding flats in the roller hit of the transmission, which are protected by wear plates.
- the compression rollers are guided on tracks on the upper spars.
- the corresponding guides on the compression rollers are rotatable and allow a compensation of positional differences of the compression rollers relative to the positions in the calibrated state. This avoids compulsion and damage to bearings caused by it.
- the gearbox is each two-stage with cones sets and spur gear sets executed. Each gear and each roller hit the compression rollers is performed with advantage on careers on the invention according to the invention in addition to use lower spars and can therefore be installed as a single module in the compression roller.
- the corresponding guides on the gear boxes are rotatable, thereby avoiding forcing in the bearings and in the connection between the compression roller and the gearbox. When changing the compression rollers, the gear can remain in the compression roller.
- the gear units follow the adjustment movement of the edging rolls through the form-fit.
- the connection point is equipped, for example, with a centering ring, which allows the transmission to follow exactly the movement of the compression roller.
- Each gearbox is connected via a media chain with the necessary media for operation and the electrical supply.
- the supply of the balancing crosshead and the compression rolls takes place via this media chain.
- Each gearbox is connected via a cardan shaft with length compensation via a laterally arranged drive motor. Alternatively, the use of only a single drive motor is possible.
- the torque distribution then takes place via additional transmission gear.
- the additional transmission gear are connected to a synchronous shaft.
- the propeller shafts are arranged on the output side of this transmission gear.
- the synchronous shaft can be multi-part and can be supported via one or more bearing housings.
- the resolution of the compression roll mill in a plurality of individual modules resulting in improved maintenance and handling and a lower susceptibility to errors compared to the prior art. Constructive changes are easy to perform.
- Essential to the invention is in particular the modular design of the compression roll balancing, the compression rolls and the main drive gear.
- the gears are mounted with laterally arranged wings on the lower spars, which allow a commuting of the gearbox according to the movement of the compression roller hits.
- the output gears of the transmission are each equipped with a separate hit to accommodate the roll neck of the compression rollers.
- the hits are equipped with an external and internal polygon for torque transmission.
- the hits are equipped with at least one centering ring, which can follow the associated gear exactly the movement of the respective compression roller.
- the advantages of the invention are that the compression roll mill is easier to maintain and easier to handle than a conventional compression roll mill.
- the compression roll mill according to the invention is more compact than a prior art compression roll mill.
- FIG. 1 is a side view, partly in section, of a first embodiment of an upsetting mill
- FIG. 2 is a side view of another embodiment of a compression roll mill.
- An upsetting mill (FIG. 1) comprises a frame 1 with crossheads 2, 3 and upper, middle and lower crossbeams 4, 5 and 6. Between the upper crossbeams 4 are in each case the upper bearing housings 7, 8 of compression rolls 9, 10 on balancing crossbeams 1 1, 12 added. The lower bearing housings 13, 14 of the compression rollers 9, 10 are received in the region of the central spars 5 by the base spreaders 11, 12.
- the compression rolls 9, 10 are each provided with roll necks 25, 26 or roll collets. equipped remotely, via which they interact with gear sets 27, 28, which transmit their drive torque to the compression rollers 9, 10.
- the gear sets 27, 28 each comprise helical gears with helical gears and bevel gear; These are each driven by a propeller shaft 29, 30.
- the propeller shafts 29, 30 are each adjustable in length and angle, so that they can carry out adjustments of the compression rollers 9, 10 in the horizontal direction, while on the drive side via (not shown) transmission with drive motors 31, 32 remain connected.
- a media chain 33 ensures the supply of gear sets 27, 28 and other components of the compression roll with electrical energy and fluid media.
- a single drive motor 34 which drives the drive shaft 30 directly via a transmission 35, while the drive shaft 29 extends over a one-part or multiple-part drive.
- Synchronous shaft 36 and a gear 37 is driven by the drive motor 34.
- the two propeller shafts 29, 30 have a common transmission 35 and that the propeller shaft 29 is connected to the synchronizing shaft 36 only via the transmission 37, for example a comb-type gearbox.
