- crank mechanism about gears drives more waves, on which countermeasures in terms of the center of gravity are arranged eccentrically. These countermeasures join in Rotation of the crank mechanism in the same direction and in opposite directions and are thus able to to generate balancing mass forces or moments of inertia so that Overall, a mass balance in the entire drive system results.
- a disadvantage of the known embodiment that overall a right complex construction of the entire drive system results because a variety of machine elements - meshing with each other over other gears - required are. This also increases the cost of the drive system and thus of the cold pilger mill, this includes not only the investment costs for the system themselves, but also the costs of the plant foundation, for Spare and wear parts and for maintenance and repair.
- DE 36 13 036 C1 discloses a drive for the rolling stand of a cold pilger rolling mill, wherein a planetary drive for driving and balancing of mass forces and mass moments is used.
- the invention is therefore based on the object, a drive system for a generic Cold pilgering mill to be designed so that as simple as possible and thus cost-effective construction is given, the mass forces and moments of inertia but limited to a reasonable level by such a structure can be.
- This object is achieved in that the at least one Crankshaft only one counterweight is assigned, the plane in the during rotation, the balance weight of the crank mechanism moves, and the plane, in which the counterweight moves during rotation are identical.
- crank mechanism the counterweight and the drive are connected to each other via toothed gearing, wherein the drive via a gear drive drives a shaft with which the counterweight is connected, and wherein the arranged on the shaft gear of the Gear transmission via a gear drives the shaft, which is connected to the crank mechanism is.
- the shaft of the crank mechanism, the shaft of the Countermass and the shaft of the drive lie in one plane, creating a special simple and easy mountable structure can be realized.
- the rolling stand and a single crank mechanism by a single push rod with each other be connected. It is recommended in the sense of a particularly simple Construction, when the push rod is cantilevered on the crank mechanism.
- the rolling stand and a single Crank drive are connected by two push rods, both sides the crank mechanism are mounted on the fly.
- the center plane (symmetry plane) of the mill stand and the center plane (Plane of symmetry) of the crank mechanism are identical; preferred are further the center plane (symmetry plane) of the crank mechanism and the center plane (plane of symmetry) identical to the counterweight.
- Another alternative embodiment provides that the rolling stand and two on both sides of and arranged symmetrically to the center plane of the roll stand Crank drives are interconnected by two push rods. It can be further provided that the drive via gear transmission, the two Crank sprockets and the two countermeasures associated with them, wherein the gear transmission are arranged laterally adjacent to a crank mechanism.
- the balance weight and / or the countermass arranged as eccentric Mass is arranged in one of the gears of the gear transmission.
- the shafts of the crank mechanism, the counterweight and the drive can be horizontal or arranged vertically.
- the push rod is mounted on journals, wherein at least one journal with at least one hole to supply the bearing between Push rod and bearing pin is provided with lubricating oil.
- the masses of the roll stand, the balance weight (or the balance weights) and the countermass (or countermeasures) are selected so that the first-order framework mass forces during operation of the drive system at least be substantially compensated.
- the proposed drive system for a cold pilger mill is characterized by a simple construction, an economical production and a ensures economic operation of the rolling mill.
- the quality of the mass balance is sufficiently good, so that a good quality of the produced Pipes is made possible.
- the drive system works therefore relatively low vibration, so that the foundation and the environment are treated gently.
- the drive system works reliably and has a long service life; the Costs for maintenance and repair are low.
- Fig. 1a and Fig. 1b the Kaltpilgerwalzrea is shown schematically. He used for manufacturing or forming a tube 22 by means of a pair of cold pilger rollers 23, which is mounted in a rolling mill, not shown here. The to be processed tube 22 is guided on a rolling mandrel 24. The rolling mill completes during the rolling process an oscillating motion, wherein stroke frequencies up to 300 per minute and more are possible.
- the tube 22 is moved in the conveying direction R during the rolling process. While the Vorhubs, which is schematically outlined in Fig. 1a, rolls the pair of cold pilger rollers 23 in the conveying direction R on the tube 22 from; during the return trip, the is sketched in Fig. 1b, the rolling of the roller pair 23 takes place on the tube 22nd against the direction of conveyance R (see arrows for direction of rotation and direction of translation).
- Fig. 2a and Fig. 2b is a drive system 1 for a rolling stand 2 in side view and plan view outlined in which the roller pair shown in Fig. 1a, 1b 23 is stored.
- the rolling stand 2 has an oscillating Exercise - that is, a reciprocating motion.
- a crank mechanism 4 is provided which has a crank arm 5 with at least a crank and arranged eccentrically with respect to the bearing point Balance weight 6 has.
- Crankshaft 4 and stand 2 are with a push rod 7 connected to both the crank arm 5 and the rolling stand 2 is arranged articulated.
- the oscillatory drive of the roll stand 2 is as follows: In a common Level 25 three shafts 12, 13 and 14 are arranged side by side and stored.
- the shaft 14 is connected to a drive 3, which is not shown in detail is; this can be an electric motor.
- the shaft 12 stores in an eccentrically arranged counterweight 8.
- the shaft 13 finally stored the crank mechanism 4, as explained above.
- On each of the three waves 12, 13 and 14 is each a spur gear 9, 10 and 11 rotatably arranged.
- the gear 9 forms, together with the gear 10, a first gear transmission; equally forms the gear 10 with the gear 11, a second gear transmission.
- the gears 9, 10 and 11 are all engaged, so that the drive 3 upon rotation of the shaft 14, the shaft 13 and the with this connected counterweight 8 drives.
- the shaft 12 drives over the Gears 9 and 10 in turn the shaft 13 and thus the crank drive 4 at.
- the shaft 12 rotates and with it the counterweight 8 in opposite directions with crank speed to the crank mechanism 4, whereby the mass balance is reached.
- crank mechanism 4 assigned only a single counterweight 8 is, with rotation of the crank mechanism 4, the rotation of the counterweight 8 synchronized he follows. Further, the plane 26, s. Fig. 2b, in which during rotation the Balance weight 6 of the crank mechanism 4 moves, and the plane 27, s. Fig. 2b, in the counterweight 8 moves during rotation identical.
- crank mechanism 4 counterweight 8 and drive 3 via gear transmission 9, 10, 11 are interconnected.
- the shaft 13 of the crank mechanism 4, the shaft 12 of the counterweight 8 and the shaft 14 of the drive 3 are preferably in the common plane 25, s. Fig. 2a.
- the balance weight 6 and the counterweight 8 are designed so that the First order inertial forces for the system consisting of rolling mill 2, balancing weight 6 and counterweight 8 are balanced when the drive system 1 moves. Mass forces of the second and higher order, which are determined by the oscillating movement of the roll stand 2 arise, however, are not balanced. Also, no precautions are taken to compensate for the moment the centrifugal force acting perpendicular to the thrust direction of the rolling mill the balance weights generated. The same goes for the moments which arise because the resultant of the inertial forces of the balancing weights not on the same line of action as the inertial force to be compensated of the rolling stand.
- the proposed drive concept has a deliberately lower quality Mass balance on, as it in the solutions according to the state of Technology is usually the case.
- this disadvantage affects in particular smaller machines are not, as the amplitudes of the emitted over the foundation Forces and moments are sufficiently low.
- Only in the case of installation locations with vibrationally particularly sensitive underground are impairments the environment possible. In these cases, however, are also with the previously known solutions vibration analysis and, where appropriate Additional measures required.
- the solution operates according to the Fig. 2a and Fig. 2b with a single push rod 7, which is mounted on the crankshaft 4 flying.
- the sketched arrangement of the push rod 7 in the center plane 15 of the roll stand requires either a correspondingly low positioning of the system, consisting from crank drive 4, counterweight 8 and drive 3, or a suitable Deflection of the produced tube from the roll center.
- FIGs 3a and 3b is an alternative embodiment of the drive system 1 shown.
- the rolling stand 2 laterally two push rods 7 and 7 ' arranged, which are also mounted laterally and flying on the crank mechanism 4.
- the Center plane 15 of the roll stand 2, the center plane 16 of the crank mechanism 4 and the Center plane 17 of the counterweight 8 are identical. This ensures that no unbalanced mass moments arise when the mass of the Roll stand 2 or the mass of the balance weight 6 and the counterweight. 8 move relative to each other.
- the gears 9, 10, 11 are below the Roll center.
- the balance weight 6 is in the illustrated case as eccentric in Arranged gear 9 arranged mass; the balance weight 6 is thus in the gear 9 integrated.
- the counterweight 8 is eccentric arranged mass arranged in the gear 10.
- FIGS. 5a and 5b The alternative embodiment according to FIGS. 5a and 5b can be seen, that a structure can be realized in which the waves 12, 13 and 14 are arranged vertically; in the solutions according to FIGS. 2, 3 and 4 these waves, however, positioned horizontally.
- the proposed drive system 1 thus has a very simple structure, which only causes low investment costs. Furthermore, the maintenance expenses relatively low due to the simple machine concept. on the other hand is also a good balance of inertia and mass moments possible, so that a low-vibration operation of the cold pilgering mill without high Effort is possible. The availability of the rolling mill is high. The production Cost-effective manufactured cold piled pipes in good quality is thus ensured.
