Definitions

  • MACiliNE FOR PROCESSING BILLET R BAR STOCK relates to a machine for selectively grinding metal billets or bars in order to remove surface defects in them.
  • a machine for processing billet or bar stock comprising a machine head.
  • a roller mechanism including horizontal table rollers for driving stock into and out of the head. and control means for controlling the rate of drive of the stock and the operation of the machine head, the roller mechanism further including co-operating sets of rolls on each side of the head for laterally gripping the stock. at least one roll in each set and a plurality of other rolls in the roller mechanism aligned therewith having horizontally inclined surfaces to provide edge support for the stock on its leading and trailing ends in dependence on the stock shape.
  • the table rollers are operable to reciprocably drive the stock into and out of the head.
  • the provision of the inclined surface rollers ensures edge support to prevent bent stock from executing a sharp undulating motion along its path of travel such as would be caused. for example. by the leading edge striking the upstream table rollers in succession or its trailing end being successively dropped off the trailing roller.
  • the co-operating sets of rolls may include plain (cylindrical) vertically-disposed pressure rollers on one side of the stock and driving rollers on the opposite side incorporating a vertical shaft portion upstanding from the horizontally inclined surface. i.c.. in the manner of a top hat.
  • the other rollers in alignment with the latter may also be of top hat form but prefe'rably they are simply disc-like structures; unlike the first rollers mentioned. these other rollers are not driven.
  • the control means is operative to drive the table rollers so as to advance the stock towards. e.g.. the grinding head, and is operator-controlled to cause the co-operatlng rollers to grip the stock and hold it firmly adjacent the head. the movements of the grinding head also being overned b the control means whereby the grinding w eel may e positioned on. and laterally traverse. a marked surface defect whilst the stock is driven forward.
  • a similar sequence may be controlled and it maybe discharged on to a side gantry or a pocket on the remote side of the head (output station).
  • the discharge of stock at the output station is effected from the control means. an appropriate set of arms being activated at the output station for this purpose.
  • FIG. I is a schematic plan view of the machine
  • FIG. 2 is a longitudinal section adjacent the grinding head showing details of some olthe rollers with various parts omitted for clarity;
  • FIG. 3 is a section through A A in FIG. 1 showing billets in position
  • FIG. 4 is a section through B B.
  • the machine com prises a horizontal roller table having a plurality of driven spindle rollers 1 extending between an input station including a gantry 2 for supporting billets and an output station including a similar gantry 3 to one side and a pocket 4 on the other.
  • a grinding head 5 is provided between the input and output stations.
  • rollers 7 are in the form of discs having inclined surfaces whilst the rollers 8 have a similar inclined disc portion surmounted by a shaft or body portion so as to define a' top hat structure. All the disc rollers 7 lie between the axes of adjacent spindle rollers i and are -idlers.
  • shafts l0 and 11 Extending alongside the output station are shafts l0 and 11 on which are secured a number of arms l2. l3 extending inwardly between the spindle rollers l and normally lying beneath the path oi travel of the stock.
  • Each of the shafts is independently pivotally movable through control mechanisms 14 and i5. so that the appropriate arms lift the stock off the roller table for discharge to the gantry 3 or the pocket 4.
  • the grinding head (FiG. 3) is reciprocably movable horizontally on a supporting carriage i7 and the grinding wheel itselfti8) is vertically movable on a slide l9 which also carries the driving motor 20.
  • the horizontal and vertical movements are effected in a plane normal to the direction of travel of the stock.
  • billets 21 which have been marked where surface defects occur are stacked on the gantry 2 and are manually discharged on to the spindle rollers i at the input station. These rollers are driven from a control console and the billet is advanced towards the grinding head.
  • the pressure rollers 9 are operated by control means so that the billet is gripped between these rollers and the cooperating top hat rollers 8. the billet (22) riding up over the inclined portion and being firmly gripped by its sides.
  • the leading pressure roller 9 is operated in advance of the 'upstream roller so that the billet is firmly held at all times alongside the head.
  • the head is activated by the control console and the grinding wheel i8 is brought into contact with the billet surface and laternily traversed across the billet face over the defective area.
  • any other marked defects in the billet may be dealt wllii in a similar manner.
  • the speed of the billet travel being varied for this purpose i.e.. the billet will travel faster in the dwell period between defects as compared with its speed whilst grinding is in progress.
  • Any defects not dealt with by the first pass. e.g.. because of the depth of the fault. may be dealt with by a reverse pass. the roller drives being reversed for this purpose. Any other sides of the billet having defects are then dealt with in the same manner.
  • the control mechanisms [4 or are operated from the console so that the billet is discharged by the arms l2. iii to the gantry 3 or the pocket 4 respectively. in FIG. 4 the arms l3 are shown lifted for discharge in this manner.
  • r y Y The gantry is suitable'for magnetic removal facilities whereas the pocket is suitable for chain slings..Aiternativciy one of these receptacles could be used for'rejccts. I
  • the drive rollers. the pressure rollers and the discharge arms may be hydraulically driven under control from the operator's console.
  • the grinding head may also be controlled.
  • hydraulically or hydraulic and pneumatic means may be used for the horizontal and vertical drives respectively.
  • Pneumatic means are particuhorizontally disposed table rollers for driving said stock into and out of engagement with the head. and t Y co-operating sets of rolls on each side of the head for laterally gripping the stock. at least one roll in each set and a plurality of otherrolls in the roller mechanism aligned therewith having surfaces inclined to the horizontal plane to provide edgesupport for the stock on its leading and trailing ends in dependence on the stock shape.
  • control means for controlling both the rate of drive of the stock along the roller mechanism and the operation of the machine head.
  • a machine according to claim 3. comprising a pivotal arm on which each pressure roll is carried.
  • a machine according to claim 5. in which the machine head includes a grinding wheel for laterally traversing the stock.
  • a machine according to claim 6. comprising a first side gantry for depositing stock on the roller table at onc'end oi the machine.
  • a second side gantry for receiving discharged stock from the roller table at the other end of the machine.
  • a machine for removing surface defects from billet or bar stock comprising;
  • roller mechanism including a plurality of driven.
  • each of said driving rolls incorporating a cylindrical, vertical shaft portion upstanding from a load bearing surface ini i i i i
