Definitions

  • This invention has for object a device for the high speed discharge of bars and sections on cooling bed in hot rolling mill plants.
  • the speeds existing in the steel bars hot-rolling plants is of about 12 - 13 m/sec for systems with openable channel or with reciprocating movement and of about. 35 m/sec for rotating drum-channels.
  • This invention is substantially intended for stock receiving and discharge devices with channels provided with openable means with reciprocating oscillating movement.
  • the main cause is in the stand-off forced by the receiving of the rolling bars downstream of the "flying shear", that cuts the continuous rolled section or bar stock, into pieces deviating it by sending a bar on one side and a bar on the other in a known stock receiving device that receives the bar by two parallel adjacent channels.
  • the channels are generally openable and closable and/or provided with other movement for discharging the bars received in turn on the underlying cooling bed.
  • This solution is preferably intended for the production of small sections, which is penalised by roller ways and cursors, respect to bigger sections due to said speed limit.
  • Purpose of the present invention is of increasing the production speed of the small sections (shaped like angles "L”, and T, U sections, square sections, hexagon sections, window sections, flat-shaped, and so on.) without however endangering their straightness, avoiding screwing not accepted by the market or by machines for the subsequent processing.
  • a device for receiving bars and sections and discharging them on a underlying cooling bed involving a toothed plate, in rolling mill plants of the type which includes movable "U" shaped channels closable by covers, for the bars receiving, characterised in that it is structured by the following combined characteristics:
  • the number of said channels is two, an internal one toward said toothed plate and an external one, and in which they lay coplanar, and the internal one extends downwards with an arm to act as a momentary stop of the advancement of the bars deposited upstream by said external channel in said transfer.
  • said channels are offset in height and the internal one is at an higher level than the external one and in which the respective arms are of the oscillating type, hinged on the outside and such not to interfere one respect to the other in the respective movement.
  • Figure 1 is a schematic front cross sectional view on the vertical-plane of a first solution of the device for the receiving and discharging of bars according to the present invention.
  • Figure 2 is a schematic view of the plant of Fig. 1 in the respective phases A),B),C),D)E), of its working.
  • Fig. 3 is a view of a alternative solution as regards the solution of Fig.1.
  • Fig.4 shows the phases of the solution of Fig.3.
  • the underlying cooling bed (6) includes a transversal translator with endless chains or endless tape or rollers herein called endless transfer means (61), upstream of a known translating system with toothed plane called cooling plate or toothed plate (62) which notoriously works comb-like to move a bar from a seat (between two teeth) to the other.
  • the upper placed device for the bars receiving and discharging (5) includes two parallel and adjacent channels arranged on horizontal-plane above the underlying bed 6.
  • Each channel is made up of an upper part as cap (51) and lower part as a real "U" shaped channel (52), the lower part (52) is movable to open and discharge the bar received on the underlying bed.
  • the bars are indicated by way of examples by 1,2,3,4 for locating them in logic succession of arrival, in order to understand the mechanism or receiving and discharging system.
  • the invention therefore consists of two channels whose lower part, substantially "U” shaped (52), is vertically movable (or almost vertically).
  • the two channels alternatively discharge the bars above the underlying transfer (61) that will carry it towards the plate (52), which will receive them by placing them one for each tooth (toothed seat).
  • the internal channel placed toward the plate must also retain the bar discharged from the external channel in order to space it from the bar 2, 3 and allow the plate (62) to rotate (advance in rotational movement) avoiding charging the bar 1 on the same tooth occupied by the bar 2.
  • the bar 1 is made free.
  • the lifting / lowering control of the two channels may be of different type (520):
  • the upper closure of the channels is supported by a longitudinal beam (50), fixed to ground by a series of columns.
  • Figures 3 and 4 substantially show a variation in which the lower "U” shaped movable channels, are moved by oscillating arms (520).
  • the transferring device may be of any type, at the most also a tilted plane.
