Definitions

  • the invention relates to a rotary tilter or inverter for bar-like or other rolled products, having tilter roller holders movable linearly one towards the other and a common guide which is pivotally supported for turning through about 180 around an axis disposed in a main casing.
  • Such devices may be associated with a rollway and since the turning axis is generally arranged beneath the rollway plane for constructional reasons provision must be taken to avoid one of the tilter rollers from moving beneath the rollway plane during the turning operation. For this reason a special drive has been provided previously for raising and lowering the turner head.
  • This basic feature is advantageously applied to a rotary tilter the casing of which is provided with support wheels and is therefore adapted to be displaced.
  • the invention provides for this case that the support wheels are arranged on rockers supported in the turner casing and which are pivotally displaced dependently on the rocking movements of the linear guide of the tilter roller holder.
  • the linear guide 8 has an inverted V-shaped cross-section as shown in FIG. 2 and embodies an internal cross-shaped recess in which the tilter roller holders 4, 6, also of inverted V- shape, engage from beneath by means of a crossshaped guide member which in FIG. 2 is indicated at 6a for the. tilter roller holder 6 shown in that position.
  • the guide faces are thus completely protected against falling scale.
  • the guide a is fitted to a rocker member 81 which forms a cover for the linear guide 8 over the range of adjustment of the tilter rollers I, 2.
  • the tilter roller holders 4, 6 are bored out and receive hydraulic cylinders 10, 1 1 respectively which are secured at 10a and 11a to the linear guide 8 and permit selective adjustment of the tilter rollers. Also these hydraulic cylinders are completely protected.
  • the turning axis for rocking the linear guide 8 is formed by two pins 12, 14 on the rocker member 9, which are supported in the main casing 16 of the turning device. All the previously described parts are thus carried from the casing 16 by the support pins 12, 14.
  • the turning drive for the linear guide 8 and all the tilter rollers l, 2 consist of a displaceable rack 18 which engages a toothed portion of the rotary pin 14.
  • a rocker 24 pertaining to the pair of guide wheels 28 is in the form of a double armed lever the second arm 30 of which lies opposite to the rocker.
  • the arm 30 has at its free end a joint 31 to which a tension-transmitting member 32, in the constructional example shown a hydraulic cylinder adapted to be locked solid, is connected which at its upper end is pivotally connected to a pin 34 which moves in a circular arc 35 during the rocking or overturning of the linear guide.
  • the pin 34 is fitted to the rocker member 19 which participates in all the turning movements of the linear guide 8 and forms a member rigid therewith.
  • the rotation of the spindle 21 obtained from the rocking movement of the two-armed lever 30, 24 is transmitted in the opposite direction to the other spindle 20 by means of the operative connection 38, 40, 36 if the pair of rockers 22, 24 extend diametrically one to the other as shown.
  • the axis of the spindle 20 is thus caused to move upwardly to the point 20'. Since the spindles 20, 21 are raised to the points 20 and 21' on turning the linear guide 8, the main casing 16 with all the parts carried by it is lifted.
  • the piston rod can be locked in the fully retracted position by cutting off the hydraulic pressure medium so that it forms a tension-transmitting link. If this locking action is removed by opening the cut-off valve, the natural weight of the turning member acts downwardly through the spindles 20, 21 on the rocker members 22, 24 which are now no longer constrained as to their pivotal movement so that the turning device with its tilter rollers l, 2 can be lowered as far beneath the plane of the rollway as is permitted by the stroke of the hydraulic cylinder 32 or until the hydraulic pressure medium is again cut off. To return the turning device into the working position shown, the piston of the hydraulic cylinder 32 is operated in the sense of drawing in the piston rod.
  • Rotary tilter according to claim 1 comprising support wheels on rockers supported in the main casing, which rockers are pivotally driven from the turning movement of the support.
  • Rotary tilter according to claim 4 in which the operative connection between the spindles carrying the pair of rockers consists of cranks offset at 180 one to the other and a coupling rod connecting the cranks.
  • Rotary tilter according to claim 3 in which the link consists of a hydraulic cylinder the piston rod of which includes a hydraulically locked position and a free position to permit lowering of the main casing and the tilter rollers thereon beneath the rollway plane, and the rockers carrying support wheels running in rails which lie externally of the width dimension of the main cas- 7.
  • Rotary tilter comprising a main casing supporting a rotatable turning assembly having means to engage bar products resting on support means, rockers keyed in pairs diametrically opposite one another on two spindles rotatably supported in the main casing and operatively connected together for opposite rotation for co ordinate lifting of the main casing during rotation of the turning assembly, at least one rocker having a second arm opposite to the rocker, and a tension-transmitting link connecting said rocker to a pin movable in a circular path during turning'of the assembly, said rockers and said arm extending approximately horizontally at the lower dead-centre position of the pin.
