Definitions

  • This invention refers to a system for the sequential receiving and conveying of bars from a rolling mill towards a collection and discharge device, the characteristics of which conform to the pre-characterizing part of the main claim.
  • a bar is intended as any type of metal rolled-section, therefore also wire or rod or section.
  • the domain is substantially directed to hot rolling-mill plants for the production of metal bars.
  • the scope of the invention is that of solving the above-mentioned problems and disadvantages and furthermore, without more burdens and without reducing reliability and without a substantial increase in encumbrances: improving the functionality and efficiency; increasing the performance of the plant in order to allow to work at a higher speed without the need to duplicate the cooling plate line.
  • Another aim of the invention is that of being able to produce very short bars, as it is known that very short bars are not realizable with traditional devices with pairs of channels which receive the bars in alternation, precisely for the limits imposed by the respective sequential action of bar receiving, braking and discharge.
  • the permissible speed of the advancing bar can reach 40m/sec, while with three adjacent devices, each of which receives and discharges one bar at a time, it is possible to reach a speed of 60m/sec. and above (70- 80m/sec) due to greater simplification and greater time available for each device to receive, brake and discharge the respective bar onto the cooling plane and underlying transversal transfer.
  • - Fig.1.- represents the front schematic view of the new bar receiving device with three adjacent devices (T 1 ,T2,T3) with receiving channels (en) for bar discharge onto the underlying cooling plate and transfer (PR) in which there are four channels (en) arranged orthogonally on the rotating drum to alternately receive the respective bars, one bar at a time 1 ,2,3 (single file feeding).
  • - Fig.2.- represents a varied view with respect to the previous one, with the channels with opposite pairs to receive a double succession of bars 1-2, 3-4, 5-6, for each drum.
  • - Fig.3. represents a variant in the method to the previous figure in which the bars received in each channel can be different 1B-1A, 2B-2A, 3B-3A.
  • - Fig.4.- represents a view illustrating the phases A) 1 B) 1 C) 1 D) 1 E) of receiving and discharge of the solution of Fig.1.
  • Fig.5. represents the plan-view of the section of the plant concerning the cutting of the bars into length and respective deviation onto the single channels (en) of the three receiving, braking and discharge devices (T1 ,T2,T3).
  • Figs.5A,5B,5C represent the corresponding sectional views of the plant of Fig.5.
  • Fig.6.- represents the perspective view of the solution of Fig.5.
  • Figs.7 and 8 provide alternative solutions with a non-rotating channel system.
  • the invention substantially includes a bar receiving and discharge group (T) made up of three bar receiving and discharge devices (T1 ,T2,T3).
  • sectioning and conveying apparatus which essentially consist of: i- an upstream horizontal deviator (Z) with two positions to deviate the bars alternatively to the right and to the left of cutting blades of shears with continuously rotating blades of known art
  • CVC shears of the start-stop type.
  • ii- a channel with two paths (H), placed downstream of the shears (CVC);
  • iii- a pair of vertical deviators (X, Y) each with vertical deviation movement in three positions;
  • iv- three horizontal deviators P.Q.R placed one above the other, namely overlying, each with horizontal movement in two positions, respectively right-left;
  • v- three fixed conveyors A 1 B 1 C which connect the exit of said three right-left deviators
  • the plant is provided with: upstream horizontal deviator (Z) on the right; right-hand vertical deviator (X) in the high position (upper); left-hand vertical deviator (Y) in the intermediate position (central); - upper horizontal deviator (P) to the right intermediate horizontal deviator (Q) to the left; lower horizontal deviator (R) to the right, therefore the bar passes through the deviator (Z), the right channel of the double path (H), the vertical deviator (X) in the upper position, the upper horizontal deviator (P) to the right, the third conveying (A) to the respective third receiving and discharge device
  • the functioning occurs according to the following phases: a)- at the beginning of the rolled-section head advancement as above, when it has reached the cutting length, the bar is cut from the continuous rolled-section deviating the same under the rotating blades of the flying shears (CVC), activating the control of the upstream horizontal deviator (Z), which passes from one position to another; b) when cutting has occurred, the head of the second bar follows, without interfering with the first bar tail already in the other channel, passing along the following, already provided, path: the left-hand channel of the double path (H); - the vertical deviator (Y) in an intermediate position; the intermediate horizontal deviator (Q) in the left position; the central/intermediate conveying (B) to the second receiving channel device (12) found in an intermediate position, through the respective bar break (FC); c)- meanwhile the first bar is braked by the bar break device (FC) placed at the entry of the respective channel of the third receiving device (T3) and therefore discharged; d)- as soon as the
  • the head of the fourth bar follows without interfering with the tail of the third bar, in the path as provided in point h), in the third conveying (A), and therefore into the third device with receiving channels (T3); m)- simultaneously the third bar is braked by the bar break (FC) placed at the entry of the first bar receiving and discharge device (T1 ) and therefore discharged onto the plate (PR).

Abstract

L'invention concerne un système permettant de recevoir les barres à la sortie d'un laminoir pour les transporter vers un dispositif de collecte et de déchargement. Ce système est un système du type comprenant des moyens permettant de dévier les barres selon différentes trajectoires, couplés à moins un dispositif (CVC) permettant de découper des segments d'une barre pendant l'avancée de celle-ci, au moins un système de freinage de barres (FC), couplé à au moins une unité de réception et de déchargement de barres, laquelle se compose d'au moins deux dispositifs (T1, T2) adjacents dotés de canaux, qui permettent de recevoir les barres et de les transférer sur un plateau (PR) de translation sous-jacent. Ce dispositif est caractérisé en ce que ledit ensemble (T) de réception et de déchargement comprend au moins trois dispositifs (T1,T2,T3) de réception et de déchargement de barres adjacents et sensiblement parallèles les uns aux autres, et en ce que lesdits moyens de déviation de barres comprennent des dispositifs de guidage mobiles permettant de guider en alternance, de manière séquentielle, les barres entrantes, par mouvement d'avance répétés, jusqu'au canal (cn) correspondant de chacun desdits dispositifs (T1,T2,T3) de réception et de déchargement, de telle manière que pendant que le premier dispositif (T1) exécute et/ou termine le déchargement d'une barre, le dernier dispositif (T3) se trouve dans une position de réception d'une nouvelle barre, et le ou les dispositifs (T2) intermédiaires exécutent l'opération de réception d'une barre.
