Definitions

  • the invention relates to an upsetting press for reducing the width of rolled material, in particular the slab width in hot wide strip roughing mills, with tool carriers arranged on both sides of the slab edge and receiving the mutually facing pressing tools.
  • a compression press of the type mentioned at the outset is known, for example, from European Patent 0 112 516 and comprises a pair of pressing tools which are arranged on both broad sides of a slab feed line in such a way that their pressing surfaces point towards one another for pressing a slab. At least one of these pressing surfaces is substantially parallel to the slab feeding direction, the other pressing surface is a surface inclined to the slab feeding direction.
  • a vibration unit vibrates the pressing tool with the parallel and inclined surface.
  • This known upsetting press further comprises a width control unit for regulating the position of the pressing tool in the slab width direction and a control which detects that the front end of the slab is arranged between the parallel surfaces of the pressing tools and which then actuates the width control device and, after carrying out a predetermined pressing, the vibration unit .
  • an upsetting press for reducing the width and reducing the thickness of slabs of various widths supplied from a continuous caster is known.
  • the slab is repeatedly processed with pressure tools moving against one another, the tool being able to freely follow the advance of the slab and the tools being operated in such a way that they perform a relatively slow operation and a relatively fast idle run.
  • the upsetting press has at least one pair of edge processing tools, which act normally on the edges of the slab, and means for quickly moving the tools back and forth.
  • the tools for reducing the thickness of the advanced slabs are held in a frame which can be freely pivoted about a crank axis.
  • the crankshaft is driven by a pair of elliptical gears, which are set so that they reduce the angular velocity of the eccentric shafts in question during the operation of the tools and increase them when they are empty.
  • the edge tools for reducing the width of the slab are connected to the crank mechanism by means of interposed hydraulic units so that the edge tools can follow the movement of the slab while working on the slab without the feed movement of the slab being impaired thereby.
  • This known upsetting press is also technically too complex and therefore too expensive.
  • An adaptation to the feed speed of the rolling stock is only possible by changing the gear with the elliptical gears according to the feed speed of the slab.
  • the crank radius selected results in a certain relationship between the number of strokes and the feed speed of the press tool, which cannot be changed at a constant speed of the main drive shaft.
  • An adjustment to the feed speed of the rolling stock is only possible as a result possible that the main drive is driven within a 360 ° rotation at different rotational speeds, the rotational speed in the engagement area must be selected so that the required synchronization between the feed speed of the press tool and the feed speed of the slab occurs.
  • the upsetting press is characterized in that for the formation of a reduction drive, each pressing tool with the associated tool carrier can be moved essentially in the direction of reduction with the aid of a handlebar system actuated by at least one crank mechanism, the crank mechanism being arranged on a crankcase and in that Tool carrier at least one feed drive acting essentially in the direction of the slab feed can be attacked.
  • each point of the press tool moves on the same cam track.
  • the tangential movement is realized by a feed drive, the kinematic dimensioning of which depends exclusively on the required feed movement of the slab.
  • the tangential movement superimposes the normal movement to the overall movement of the press tool. It is therefore expedient that the feed drive can be synchronized with the reduction drive in accordance with the feed movement of the slab.
  • the handlebar system consists of two parallel rods articulated to the same length on the tool carrier and that each parallel link on the crankcase is assigned a crank mechanism with the same crank radius and the same crank angle.
  • This handlebar system in conjunction with the synchronization, ensures that the movement of the press tool runs exactly in the normal to the direction of movement of the slab.
  • Push rods can also be used instead of the parallel link.
  • the feed drive is designed as a crank drive or as a toggle lever drive and with the main drive for normal movement, i.e. is synchronized with the reduction drive for the pressing tools.
  • the crank radius of the crank mechanism for example, must be made variable using a sliding block construction.
  • the design of the feed drive as a hydraulic cylinder is particularly advantageous.
  • the movement of the hydraulic cylinder can be controlled in the form of a path / time function so that the synchronization of the pressing tool with the slab to be pressed laterally is ensured for any feed size.
  • the pressing tool is guided by a guide roller which rolls on a guide track which is fixedly arranged in the machine frame.
  • the contour of the guideway is designed such that the normal movement inevitably produces a tangential movement of the order of magnitude, which brings about the required synchronization.
  • the inclination of the guideway can be changed, so that with sufficient approximation, the synchronization of the feed speed of the pressing tool with the feed speed of the slab to be pressed also occurs for different sizes.
  • the angular position of the handlebar system is designed such that the tangential force component of the crank mechanism points against the direction of the feed speed of the feed drive during pressing, so that the power of the feed drive becomes part of the forming capacity when reducing the slab width.
  • FIG. 1 shows the horizontal section through an overhanging upsetting press 1 designed according to the invention for reducing the width of slabs 2 in a hot wide strip roughing mill, the slabs being fed almost continuously from a slab casting system upstream of the upsetting press but not shown in detail.
  • Driver rollers 3, 4 are arranged in front of the upset press 1 and behind the upset press.
  • the slab 2 passes through the slab crushing stand in the direction of movement provided with number 5.
  • the upsetting press has stands 6.
  • a crankcase 9 is adjustably guided.
  • the crankcase is adjusted with the aid of a mechanical adjustment 31.
  • a hydraulically acting piston / cylinder construction can also be used as the adjustment device, which is supported in each case on the stand 7, 8.
  • Pressing tools 7 are arranged on both sides of the slab 2.
  • the pressing tool 7 has a reduction drive 12 acting in the normal direction, ie perpendicular to the slab 2, and a feed drive 13 acting in the tangential direction, that is to say parallel to the slab 2.
  • the reduction drive 12 is formed in that each tool carrier 8 with an associated crankcase 9 with the aid of a of at least one crank mechanism (eccentric 14) actuated steering system (pressure tappet 18) essentially in the direction of reduction is movably connected, the crank mechanism 15 being arranged in the crankcase 9.
  • the feed drive 13, which acts essentially in the direction of the slab feed, engages on the tool carrier 8.
  • Crankcase 9 and the fulcrum 29 of the feed drive 13 are connected to form a structural unit with the aid of the connecting support 30.
  • the link system 16 consists of two parallel lengths 17 and 18 articulated on the tool carrier 8 and each of these parallel links is on the crankcase 9 each a crank mechanism 15 with crankshafts 19, 20 is assigned, the crank radius of which is identical to one another and to which the parallel links are articulated at the same crank angle.
  • the parallel links are articulated on the tool carrier at the same distance from each other.
  • crank drive for the steering system moving the pressing tool 7 in the normal direction and the use of a crank drive for the feed drive moving the pressing tool in the tangential direction enables, for example, a synchronization of the reduction drive and the feed drive in accordance with the feed movement of the slab.
  • the pressing tool 7 can, in rapid succession, adjust the slab feed speed (without relative movement to the slab) in the normal direction, then push it forward, then move back at a distance from the slab, finally attach it normally to the slab edge and press it again in the normal direction without relative movement to the slab.
  • the feed drive 13 is formed according to FIG. 3 from a piston-cylinder unit 22 whose piston 22 'on the tool carrier 8 and whose cylinder 22 ⁇ is connected to the crankcase 9 or to the connection 30 of the upsetting press.
  • This piston-cylinder unit 22 can be controlled in the form of a path / time function so that the movement synchronization of the press tool and slab is ensured for any feed size.
  • the control technology used for this corresponds to the state of the art and is therefore not explained in detail.
  • Fig. 4 shows the feed drive 13 for the press tool 7 or for the tool carrier 8 with a guide roller 23 arranged on the press tool, which runs on a guide track 24.
  • the guide track or the guide body 25 forming the guide track is fastened in a suitable manner to the stand 6 by means of a swivel joint 26.
  • the inclination of the guideway can be adjusted in that the guiding body can be pivoted through certain angular amounts in the swivel joint.
  • an adjusting mechanism acting on the guide body 25 and on the crankcase is provided, which can consist of an adjusting screw 27 articulated on the guide body 25 and an adjusting nut 28.
  • One with a hydraulic medium can also be used as the adjustment mechanism controllable piston-cylinder unit are provided.
  • the inclination of the guide path of the guide body can be adjusted depending on the selected feed speed of the slab so that the feed speed of the press tool and the feed speed of the slab are equal, so that relative movements between the slab and the press tool during the lateral compression of the Slabs are excluded.
  • the pressing tool 7 can be a highly resilient wear part that can be detachably connected to the tool carrier 8 and provided with pressing surfaces 10, 11.
  • the crank mechanism 15 on the crankcase 9 can be connected on the drive side to a conventional spur gear.
  • the flying upsetting press according to the invention for reducing the slab width can also be connected to conventional devices for reducing the slab thickness.
