Planet whale plant and rolling.

The invention "relates to a Yerfahren for operating a planetary mill and a planetary mill in the US Patents 2,710,550 and 2,811,060, in US Patent Application Serial Ιο» 436075 of the same applicant from H ₀ in June 1954 under the name "planetary mills with double drive "as well as in the British patent specification 609 706 (E * M. Picken) described type, in which successive pairs of work rolls each on one side, progressively wander through a zone of plastic deformation of a workpiece while they are in contact with The work rolls are arranged in planetary arrangements around one of two backup rolls etc. The movement of the work rolls while they are in contact with the workpiece usually takes place in the

This reduction ⁰ is $ 97 and leads to a change in length to 55 times the original length of the slab.

The invention is primarily aimed at eliminating difficulties which experience has shown during 009835/0132

rend of the actual action of the rolling mill on a workpiece or a series of workpieces. It has been shown that certain operational conditions occur during the rolling of slabs, which tend to the proper reduction in strength of the work _; to disrupt the piece and the operation of the rolling mill as a mechanical unit and which in some cases lead to critical mechanical damage to the rolling mill, for example the breakage of gear teeth, torsional deformations of shafts, damage to keyways or the like.

These difficulties could now be attributed to irregularities in the operation of the work rolls, which one could best ^{denote by the expression "disturbances of the synchronous running 11} in its broadest sense. There are previously known rolling mills of the type with which the invention is concerned, in which the pairwise opposite working rolls grip the workpiece at the same time, and this is a point of the synchronous running. It has, however, shown that when ά anything 'occurs that disturbs the proper interaction of the rollers during the rolling operation, the previously opposite to effect a simultaneous attack Work rolls on the workpiece, which usually include gears, shafts, clutches and drive devices, are subjected to shock loads of sometimes unexpectedly high levels

themselves.

a condition develops in which the work rolls deviate from their perfect interaction, further operation of the rolling mill the degree of the defect increased in temporal correspondence. The greater the deviation the working rolls in the zone of plastic deformation is of perfect interaction, the more greater is the force required to prevent further deviation from perfect interaction. It has proven impossible to remedy these deficiencies by removing the synchronizing devices of the previously known type is particularly heavy and rigid.

In the planetary rolling mill, forces occur which possibly ensure the perfect interaction of the work rolls in the area of plastic deformation despite extreme rigidity interfere with the means previously provided for synchronization ». Bite forces arise during of rolling due to various causes, including changes due to wear, local Thermal expansion, irregularities in the flow of lubricant and irregularities in the workpiece itself. The workpieces can not only differ in terms of their physical shape in different parts but there can also be sporadic temperature differences and temperature differences between the

both sides occur * load always- there is a temperature difference ih oiler liohtung the I * ength of the workpiece _t the rear! näe the workpiece in the allege "my of lower femper ^ ture thereof or of the subsequent workpiece as FCOS · front end. For example, a rolling mill with re-ground rollers, which has also been checked with regard to synchronous running, can work perfectly during half a day and then gradually develop a disturbance that manifests itself in the fact that the front Έηάβ each Sheet metal faces sharply down (or up) rather than horizontally.

Synchronous operation is also influenced, also disturbed.

It has now been shown that by careful observation the position of the slab in terms of both vertical and lateral deviations at the entrance to the zone of deformation, as well as any tendency of the slab to change its position, enables the Falling out of the rollers from the synchronous operating state to foresee with certainty and a return of the slab to its symmetrical position with respect to the rolling mill to bring about by moving the synchronizing parts in a direction which is the direction of such Shift is opposite. The development of this new process, a planetary rolling mill too operate, enables rolling without interruption, practically eliminating the risk of mechanical Damage. The invention provides means for Allow such a setting. The devices according to the invention can be used by an operator, which is able to quickly recognize any faulty operation of the rolling mill, operated but they can also be controllable by automatic devices.

The invention thus creates devices with the help of which the simultaneous attack of the opposite

The invention also provides devices with which Help the plane of symmetry of the plastic deformation zone with respect to the plane of symmetry of the rolling mill is adjustable during the rolling process ·.

When speaking of such corrections and adjustment processes, it must be taken into account that, if necessary, to overcome certain specific difficulties, irregularities in the workpiece itself usually include a controlled degree of deviations from synchronous operation, a controlled degree of inclination or a controlled deviation of the plane of symmetry of the workpiece of the plane of symmetry of the rolling mill can be desired, and that the expression "•• control" in the present explanations is to be interpreted broadly enough to deliberately induce any desired deviation from synchronous operation 009835/0132 for special purposes

Pig α 1 shows a planetary rolling mill with a housing, one part of which is shown at 1, two backup rolls 2 and 3, which are mounted in the housing, one each set 4 and 5 of planetary arrays surrounding each back-up roll beitswalzen, as well as a slab 6, which in the area of the plastic "deformation of the rolling mill to a sheet metal? is to be rolled out, Bie slab 6 is in the zone the plastic 7erformung by means of a pusher device 8 on the piston rod 9 on a suitable ! Bisch 11 mounted pressure medium-operated cylinder 10 introduced. When operating planetary rolling mills of this type, it is customary to roll the slab 6 in a heated state, but this is not a necessary one Limitation of the invention, since the rolling mill is of course also operated as a cold rolling mill, if desired can be.

Bie shown in Fig. 1 special novelty is that for both backup rolls 2 and 3 bearing blocks or position elements are provided, which are also the adjustable Form adjusting devices. These bearing blocks have an arcuate outer contour and are circular Recesses or! »More mounted in the housing 1, while the necks dör backup rollers 2 and 3 eccentrically are mounted in the itager blocks. Bie bearing blocks are indicated in the figure at 12 and 13, and there are

directions for rotating the bearing blocks in the housing provided, whereby the axes of the rollers 2 and 3 simultaneously away from one another or towards one another are movable. Although eccentric bearing blocks are known, However, the mobility of the bearing blocks according to the invention is along its circumference to one Circular arc limited by only approx. 60 °. In addition, the eccentricity is many times that of the known eccentric bearings that allow a full turn chen. ■

Although there are numerous ways to twist the bearing blocks, Pig is in. 1 shows a simple arrangement in which the piston rod 14 of each pressure-medium-actuated cylinder 15, which is mounted at the upper end of the housing 1, is connected to the bearing blocks 12 and engages at an eccentric point The pressure-medium-operated cylinder 17 mounted at the lower end of the housing 1 is connected to an eccentric point of each bearing block 13. As a result, when the pressure cylinders are pressurized, the bearing blocks 12 and 13 experience limited rotation or pivoting movement the axes of the support rollers 2 and 3 against each other simultaneously to or away from each other to be moved. With simultaneous opposite law ter 009835/0132

ter and the same operation of the two "printing cylinder is the job without the simultaneous change 'dei the plane of symmetry of the rolling mill altered W / ^{EHN; which:} - the two cylinders at the same time but, instead ^{counteracted:} sets are the same direction is pressed, the adjustment of the rolls of the mill remains essentially unchanged, but the symmetry experiences a "shift" If the two cylinders are actuated to different degrees, the inclination can be changed and the plane of symmetry can be shifted at the same time, _etc.

Bas presence of an adjusting device for each support roller enables the operator (or, if desired, an automatic device), during the rolling process the smallest setting changes in the position of the To make the plane of symmetry of the rolling mill quickly and precisely. The arrangement has a number of other advantages ο You only need to change each adjusting device to move a distance that is only slightly greater than half the thickness of the slab. to complete the rolling mill to open and to release the bramime in the event of compression. Another advantage is that the arrangement enables a considerable reduction in the dimensions of the rolling mill housing Planetary rolling mills built so far are the ends of the upper backup roll or their.

Cylinders 26 and 27, the piston rods of which are connected to the bearing blocks, can be controlled. A considerable force is generally required to feed the slabs into the planetary rolling mill and, as a result, a pressing action of the feed rollers 22 and 23 is usually required on the slab, causing a slight reduction in the thickness thereof. The assembly ^ and adjustment devices for the feed rollers as described above act, not just as. Anstellittmittel -to regulate the clamping effect of the feed rollers on the slab, but rather the feed rollers can obviously be used in opposite directions actuation of the pressure cylinders 26 and 27 to raise and lower the plane of symmetry of the slab in such a way that this at the feed point with the plane of symmetry of the area the reduction in thickness between the planetary roller assemblies coincides. The feed rollers 22 and 23 can be driven by means of a suitable device O

It should be noted that there is an independent adjustability

the 009835/0132

of the feed rollers in the type described _f, in particular for changing the position of the plane of symmetry of the slab, is often sufficient to correct incorrect operation of the rolling mill without changing the setting of the planetary roller sets, although of course both the feed rollers and the planetary roller sets, if desired, can be set at the same time or in sequence.

It has also been shown that if ever a separate Drive for the feed rollers 22 and 23 is provided, a slight imbalance in the operating speeds of the feed rollers leads to the fact that the exiting slab is slightly liaße against the one with the lower speed driven feed roller moved towards. Characteristically, this also enables a regulation to reduce the inclination of the planetary roller mill deviate from perfect synchronous operation.

During normal operation, the slabs are fed one after the other from a continuously operating furnace located in front of the rolling mill. Such a furnace can operate as a high-frequency electric induction furnace, but other types of heating are possible. During continuous operation of the rolling mill, the front end of the following slab is used for this purpose, the rear end 009835/0132

These facilities exist from Klenuiiwalzen 28 and 29, which in the illustrated embodiment are mounted in bearings on lever arms 30 and 31 attached to the rolling mill housing the pinch roller 29 connected sub-assembly can by sine adjustable support device 32 connected to a rope of the foundation of the rolling mill in its position ■ be held. The upper arrangement can be adjusted by means of one or more hydraulic fluid motors 33, which are attached to the rolling mill housing. The clamping rollers 28 and 29 are driven in any suitable manner.

It is advantageous to remove the sheet metal web 7 from the planetary roller arrangement under tension. Such a tensile force assists the pushing force which the feed rollers 22 and 23 exert on the slab. As in Pig; 2 , this can be achieved by devices that are directly connected to the rolling mill and consist of pinch rollers 34 and 35 which are mounted in bearings in lever arms 36 and 37 articulated in km of the rolling mill eiristöllba ^ ett facility 'device' 38 worn soapy ¹ ViM ¹ eüää ¹ IIe ^ tellting der obreren '

Pig «3 shows a further embodiment of the invention, • with the supply rollers, planetary roller sets and rollers on the exit side of the planetary roller sets in the same Housing are housed.

009835/0132

the same facilities. Here, too, it is usually possible to have the housing as a single casting manufacture and the associated advantages of higher rigidity and lower costs themselves to achieve relatively large rolling mills. However, it is entirely within the scope of the concept of the invention, especially in the case of particularly large rolling mills, one of several Provide parts screwed together housing.

The rigidity of mill casings is important given the inevitable fluctuating nature of the loads acting on the housing as a result of the cyclical Changes in the size and direction of the roll separation forces, according to the number of pairs of work rolls of the planetary rolling mill, which are in contact with the workpiece at a given moment. These cycles are usually repeated between 20 and 80 times a second, and can, if the housing is not very rigid, can lead to harmful vibrations and excessive noise. Compared to known rolling mill housings is that according to the invention not only more rigid in the direction of the roll separation forces, but also extremely rigid in the direction of the feed force. This is of particular importance since the feed force oa 1/3 of the Force of the rolling pressure and the known housing with their long vertical columns in this direction

have only a very low stiffness - of course is it an advantage that the possibility is given, " the feed pinch rollers, the planetary roller sets and one Tension generating device or a flat rolling mill as close together as possible in the direction of movement of the workpiece.

From the above description it can be seen that the construction of FIG. 3 allows the adjustability of the symmetry plane of the entering slab and the exiting sheet metal sheet in relation to the plane of symmetry of the area the reduction in thickness between the planetary rolling mills.

As will be recognized by those skilled in the art, the above can be used as Rolling mill housing rotatably mounted described bearing blocks by means of a variety of mechanical, hydraulic or electrically operated devices can be rotated. The setting of any of these Facilities can be fully operated by the Operators of the rolling mill are subordinate to them, but the setting can also be made by automatically acting Facilities to be controllable.

The hydraulic system for actuating the bearing blocks can, as FIGS. 8 and 8a show, from a suitable one

009835/0132

There are electro-hydraulic control slide 46, which is connected to a hydraulic pressure cylinder, for example 15, at one point above and below the piston 47 playing therein. The control slide is also connected to an electrically driven liquid pump 48 or another suitable one Pressure medium source and connected to a sump or container, which is indicated at 49 in ligo 8. The control slide is used to maintain a vaherbe true en pressure difference on both sides of the piston 47, which is proportional to the voltage of the electrical signal supplied to it. The size of the hydraulic pressure difference, which corresponds to the voltage value "lull" of the supplied electrical signal, can be mechanically adjusted in advance, as is usually possible with electrohydraulic control slides ₈

A linear precision potentiometer 50 can be mounted on the pressure cylinder 15 and connected to a rod 51 which forms an extension of the piston rod. In this way the potentiometer follows the movements of the piston exactly. In S ¹ Ig. 8a, the potentiometer 50 is indicated at 50a and, as can be seen, connected to a reference potentiometer 52 to form a Wheatstone bridge which is fed by a current source 53. The reference potentiometer 52 is by the operator 009835/0132

can be set manually by the operator Disturbance of the equilibrium of the resistances of the bridge generates a signal voltage which is generated by a is amplified at 54 schematically indicated amplifier. This amplifier is, as shown, of a Suitable power source 55 is fed with alternating current and also connected to the control slide 46. To this Way, a pressure difference is generated between the two sides of the piston 47 L, which is determined by Signalspannimg as well as the selected mull signal setting of the slide , 46 is proportional. The electrical signal in the device caused by the imbalance in the The measuring bridge is generated either from the change in the setting made by the operator of the reference potentiometer 52 or from the movement of the piston connected linearly to the potentiometer 50 47 ago.

The changes in the basic forces that strive to achieve the Rollers (e.g. in the planetary roller sets) to separate from each other and those of the resistance of the rolling Material against the deformation of the same and which approximates the nature, width, Temperature and the percentage of reduction in thickness of the rolled material depend on generate electrical 009835/0132

U02690

see signals that create differences between the hydraulic pressures on the two sides of the piston 47 that offset these changes in the rolling separation force. Any change in the basic forces tending to separate the rollers, if sufficient to overcome the friction inherent in the pitch mechanism, will cause the piston 47 to move. If the operator wishes to change the roller spacing by the thickness To either increase or decrease the size of the rolled material, or to adjust the plane of symmetry, this is achieved by adjusting the reference potentiometer 52 _{or the like}

By suitably designing the mechanical parts and choosing the control parts, the ratio of the change in the roller separation force to the change in the roller spacing can be made so high that a substantial change in the roller separation force does not change the position of the piston 47, or only a negligibly small change produces the thickness of the exiting strip plate., on the other hand, when the accuracy of the thickness of the rolled strip plate plays a role, can se known means for continuously M _e the thickness of the strip plate SEN be provided, and the correction of the thickness may be either manually or automatically take place.

Using known devices for the continuous mass of the sheet metal thickness, which have an electrical Generate electricity, an automatic control of the sheet thickness can be achieved, because it is possible to cause changes in the electricity generated in this way, with the help of which a continuous adjustment of the reference potentiometer 52 enables wircU

If the work rolls are supported by massive driven backup rolls (as in Fig. 7), the rings are usually equipped with sprockets and interconnected. They hang _s which are freely rotatably mounted on one of the back-up rolls are connected to each other by a shaft that carries gearwheels These shafts are connected at their ends by vertical shafts and bevel gears. In theory, such a vertical shaft would be sufficient. In the interests of greater torsional rigidity, however, it is preferable to arrange a vertical shaft on either side of the rolling mill.

On the right in 3? ± g * 7, the shaft 79 is divided into two parts designated 79 and 79a, respectively. These ropes are serrated 80 and 81, and a positive drive between the two parts is achieved by a sleeve or coupling 82 with internal means for engaging the splines _? as a longitudinal movement of the coupling has to allow 82 a mutual rotation of the two shaft parts 79 and 79a to follow "to a setting and determine the clutch 82 in the l & ngsricntung, a screwed in a fixed panel 84 member 83 is provided. the clutch 82 is located against the upper surface of the G-thread link at _o

The upper ends of the two thread links 83 u? id 83a, are with gear rings 86 and 8? Mistake. Both · Ring gears are engaged with the teeth of a rack 88, which is transverse to the rolling mill and in the Is mounted displaceably in the longitudinal direction. A movement the rack generates corresponding movements of the 'G-thread members 83 and 83a "
