Definitions

  • the invention relates to a device for tensioning and balancing the pressing tool carrier and crankcase of an upsetting press for reducing the width of rolled material, in particular for reducing the slab width in hot wide strip roughing mills with pressing tools accommodating pressing tools arranged on both sides of the slab edge, which can be moved with the aid of a crank mechanism in the direction of slab reduction.
  • pressing tools which are received by tool carriers, are arranged on both sides of the slab edge in order to reduce the width of slabs in a hot wide strip roughing mill.
  • each pressing tool with the associated tool carrier is moved with the aid of a steering system actuated by a crank mechanism in the direction of reducing the width of the slab, the crank mechanism being arranged in a crankcase.
  • the crank mechanism consists of two driven eccentric shafts; A connecting rod is mounted on each eccentric shaft; the connecting rod head is connected to the tool carrier for transmitting the compression forces.
  • a feed drive acting essentially in the direction of the slab feed acts on the tool carrier.
  • the movement of the pressing tools for the reducing Pressing and for the advancement of the pressing tools can be controlled separately from one another, so that synchronization of the movement of the pressing tools with the movement of the slab to be pressed laterally is ensured for any feed size.
  • This upsetting press enables the width of the slab to be continuously reduced to values specified by rolling technology.
  • the plain bearing between the connecting rod head and the tool carrier as well as the roller bearings of the eccentric shafts are exposed to high loads and must be designed as free of mechanical play as possible due to the superimposed reduction and feed movement of the pressing tools and due to the high pressing forces.
  • the object of the invention is to develop the compression press described at the outset, in particular design measures for bracing tool carriers and crankcase and a balancing of the crankcase on the compression frame, with which the slide bearings between the connecting rod head and the tool carrier as well as the roller bearings are as free of play as possible in any load condition of the compression press and are evenly resilient.
  • the upsetting press according to the preamble of claim 1 is characterized in that an articulated linkage guided through the crankcase engages approximately centrally on the tool carrier, that two outer linkages articulated on the crankcase act at a distance from the central linkage, and that the central linkage and the outer linkage also such the linkages on tension resilient tensioning devices are connected, which in turn are firmly connected to the crossbar of the uprights of the compression frame.
  • the tool carrier is first braced against the connecting rod heads of the crank mechanism, so that any mechanical play in the slide bearing between the connecting rod head and the tool carrier is removed, even in the unloaded movement phase, in which the pressing tool after pressing is removed from the slab edge is moved.
  • the tensioned center linkage also causes a certain load on the roller bearings of the eccentric shafts of the crank mechanism, so that any mechanical play that may be present is removed from these roller bearings, even in the unloaded movement phase of the pressing tools when they are moved back from the slab edge. These measures reduce mechanical noise and prevent premature wear the storage. Furthermore, with the help of the outer linkage and the associated clamping devices, the crankcase is firmly clamped to the crossbar of the compression frame, so that all reaction forces emanating from the pressing process are uniformly introduced into the compression frame of the press. The play in the mechanical adjustment, in particular the play in the pressure spindle and in the pressure bearing, is also removed.
  • the central linkage has a circular guide movably arranged in the crankcase, that a pull rod mounted in articulated eyes is arranged on the tool carrier and the round guide on the one hand and that on the other hand a clamping device elastically trackable to the movement of the tool carrier engages in an articulated manner, which is firmly connected to the crossbar of the uprights.
  • the central rod of the superimposed movement of the pressing tool and the tool carrier can be tracked in the direction of advance of the slab and in the direction of reduction perpendicular thereto, and the tensile forces required for the play-free connection of the tool holder and connecting rod head as well as for the play-free mounting of the eccentric shafts can be carried out directly in any movement position of the press tool Crossbar of the scaffold stand are included.
  • the tensioning device for the central linkage is a piston-cylinder unit with a pressure accumulator that can be acted upon twice with a hydraulic pressure medium, the piston rod of which is enclosed in an articulated eye provided on the round guide and provided with a ball socket, and the cylinder of which Contact element and support plate is supported on the crossbar.
  • the pressure accumulator also enables the tensile forces to be controlled in a controllable manner to the movement of the press tool.
  • the piston-cylinder unit assigned to the central linkage has a control device for the tensile forces applied, which is dependent on the drive of the crank mechanism.
  • each outer linkage be equally spaced from the central linkage and that the outer linkage at the same time be the piston rod with a hydraulic pressure medium is a double-acting piston-cylinder unit, the piston rod being encased in an articulated eye arranged on the crankcase and provided with a ball socket, and the cylinder being supported on the crossbar by means of a contact element and support plate.
  • crankcase, the crank mechanism and at least the tool carrier can be displaced as one structural unit into the assembly or disassembly position with the aid of the piston-cylinder unit of each outer linkage.
  • the assembly or disassembly position is predetermined by the arrangement of the rail arrangement running transversely between the uprights and on one side of the uprights, on which the structural unit can be moved from the compression frame onto the construction site.
  • each joint eye of the central linkage or external linkage be arranged in a holder which can be detached from the crankcase, preferably by means of pins and bolts .
  • Fig. 1 shows the horizontal section through the overhanging upsetting press 1 for reducing the width of slabs 2 in a hot wide strip roughing mill, the slabs being fed almost continuously from a slab casting plant upstream of the upsetting press but not shown in detail.
  • Driver rollers 3, 4 are arranged in front of the upsetting press and behind the upsetting press.
  • the slab 2 passes through the slab crushing stand in the with point. 5 provided direction of movement.
  • the upsetting press has scaffold stands 6.
  • a crankcase 9 can be set in the upsetting frame of the upsetting press between its scaffolding stands.
  • Pressing tools 7 are arranged in pressing tool carriers 8 on both sides of the slab 2.
  • the press tool and the tool carrier have one in the normal direction, i.e. Reduction drive 10 acting perpendicular to the slab 2 and a feed drive 11 acting in the tangential direction, that is to say parallel to the slab 2.
  • the reduction drive is formed in that each tool carrier 8 with the aid of a handlebar system actuated by two eccentric shafts 12 and containing two connecting rods 22, essentially in Direction of the slab to be reduced in width is movable.
  • crank mechanism 10 For clamping and balancing the press tool carrier 8 and crankcase 9 on the compression frame 6 of the press 1 and for moving the tool carrier essentially 8, crank mechanism 10, and crankcase 9 existing unit attacks on the tool carrier an articulated rod 13 guided through the crankcase 9 approximately in the middle and at a distance from this central linkage, two further articulated outer rods 14, 14 'act on the crankcase 9, the Center linkage 13 and the outer linkage 14, 14 'are connected to such tensioning devices 15, 16 which are capable of withstanding tensile loads, which in turn are firmly connected to the crossbar 17 of the uprights 6 of the compression frame 1.
  • Fig. 2 shows an enlarged section - partly in section - of the arrangement of the tie rod 18 as part of the central rod.
  • the pull rod is mounted on a projection 19 of the tool carrier 8 in an articulated eye 20.
  • the other end of the pull rod is mounted in a further joint eye 20 ', which is connected to a round guide 21 which is arranged in the crankcase so as to be longitudinally movable.
  • the tie rod 18 is located in the middle between the connecting rods 22, which rotate about the eccentricity 24 on the eccentric shafts 12 mounted in roller bearings (not shown).
  • the connecting rod heads 25 are seated in slide bearing half-shells 26, which are molded into the tool carrier 8.
  • the pins 27, 27 'of the articulated eyes 20, 20' of the pull rod 18 are mounted in a ball socket, not shown here.
  • the other end of the round guide 21 is provided with a further joint eye 29, which is part of a holder 23, the holder being screwable to the round guide.
  • FIG. 3 in continuation of FIG. 2, the circular guide 21 arranged in the crankcase can be seen, and that this circular guide is surrounded by a sliding bush 28 which can be supplied with lubricant.
  • the second section of the central linkage 13 is attached.
  • This section is also the piston rod 31 of a piston-cylinder unit 32, which is provided with a pressure accumulator, not shown, which can be integrated in this unit, for example, as a gas pressure accumulator.
  • the cylinder 33 of the unit 32 is supported on the crossbar 17 with the aid of a contact element 34 and a support plate 35.
  • the crossbar consists of a plate welded construction in which the piston-cylinder unit 32 is arranged.
  • the tool carrier 8 Via the pull rod 18, the round guide 21 and the piston rod 31, the tool carrier 8 is pulled backwards against the crossbar of the compression frame and the pressure accumulator of the piston-cylinder unit 32 acts on the tool carrier 8 like a prestressed spring.
