Description

       

  Appareil pour le perçage de     profilés        laminés       Les ouvrages en acier sont constitués le plus  souvent de profilés qui sont tronçonnés à la longueur  voulue dans des profilés laminés et sont ensuite per  cés afin de pouvoir être assemblés à d'autres profilés  par des rivets ou des boulons. Pour percer des trous  à travers les ailes des profilés, il est d'usage de  déposer ces profilés sur un     support    horizontal et de  percer au moins une     partie    des trous à l'aide d'un  ou plusieurs forets horizontaux.  



  A cette fin l'emplacement des trous à percer doit  être déterminé exactement par rapport à un ou plu  sieurs plans de référence du profilé. Par exemple, les  positions de trous percés dans les ailes d'une section  en double T seront déterminées par rapport à un plan  de référence passant par le plan de symétrie de  l'âme.     Etant    donné les tolérances acceptées dans ce  domaine, le plan de référence peut ne pas être situé  à la hauteur voulue au-dessus du     support    et si la  position des forets est réglée par rapport à la hau  teur du support, les trous pratiqués dans les ailes  ne seront pas correctement positionnés.

   De plus un  profilé laminé peut être légèrement incurvé selon un  plan     vertical,    si bien que la hauteur du plan de  référence au-dessus du support peut changer à moins  que des moyens soient prévus pour     appliquer    le pro  filé vers le bas sur toute sa longueur de façon qu'il  devienne parfaitement rectiligne. Ces     difficultés    sont  bien connues et pour les éviter on a recouru à dif  férents expédients simples tels que     l'insertion    de  coins entre le     support    et le profilé.  



  La présente invention a pour but de     supprimer     ces difficultés, et a pour objet un appareil pour le  perçage de profilés laminés qui est caractérisé en ce  qu'il comprend un support horizontal, des moyens  pour fixer horizontalement en position le profilé sur  le support, au moins un foret horizontal dont la posi  tion peut être réglée en hauteur et au moins un    organe palpeur porté par un châssis rigide et pou  vant être abaissé et élevé par rapport au châssis de  façon     qu'il    puisse     enregistrer    la hauteur par     rapport     au support d'une face du profilé à percer placé sur  le support.  



  Le dessin représente, à titre d'exemple, une  forme d'exécution de l'appareil objet de l'invention  La     fig.    1 en est une vue en plan schématique.  La     fig.    2 en est une vue en élévation schéma  tique.  



  La     fig.    3 montre des profilés de     différentes    sec  tions dans leur position de perçage, et  la     fig.    4 est une vue de     détail,    partiellement en  coupe, de l'organe palpeur et de l'indicateur.  L'appareil représenté au dessin est capable de  percer simultanément les deux ailes d'un profilé 8  dont la section est en double T.     Il    comprend deux  socles de perçage 2 et 4     coulissant        horizontalement     et verticalement et     portant    chacun six forets hori  zontaux 6 destinés à percer lesdites ailes.

   Le profilé  8 repose sur un     support    constitué par un convoyeur  formé par des rouleaux commandés 10. De chaque  côté des socles de perçage sont disposés des organes  de fixation 12 et 14, les organes 12 étant fixes et les  organes 14 pouvant être déplacés horizontalement.  



       Comme    les deux ailes par lesquelles le profilé 8  repose sur le     support    peuvent présenter des dimen  sions variables, les différences pouvant varier d'une  aile à l'autre et être même de sens opposés par rap  port à la dimension théorique, les deux socles de  perçage 2 et 4 peuvent être réglés indépendamment  l'un de l'autre dans le sens de la hauteur de façon  connue, non représentée. Pour déterminer les     écarts     il est prévu deux organes palpeurs 16 constitués cha  cun par une tige     verticale        portée    par un châssis.

   Le  châssis comprend une barre transversale 18     wppor-          tée    par des piliers (non     représentés)    s'étendant de           part    et d'autre du convoyeur et située dans un plan  parallèle au plan de     symétrie    des socles mais déportée  par rapport à ce dernier. Ainsi le châssis n'interfère  pas avec les forets. Sur la barre transversale 18 sont  montés deux chariots 20, 21, chacun de ceux-ci  présentant un bras 22 s'étendant jusqu'au plan de  symétrie des socles et     portant    chacun un organe  palpeur 16.

   Les organes palpeurs sont situés dans  le plan de symétrie desdits socles et sont destinés  à être amenés dans un plan voisin de celui dans  lequel est située l'aile correspondante du profilé 8.  Le chariot 20 n'est réglable, le long de la barre  transversale, que sur une     courte    distance pour pou  voir tenir compte des différences d'épaisseur des  ailes et aussi de la présence de plaques addition  nelles tandis que le chariot 21 est réglable sur une  grande distance afin de pouvoir tenir compte de  profilés de largeurs     différentes    dans le sens hori  zontal.

   Ce réglage peut s'effectuer manuellement ou  automatiquement ; dans le cas d'un     profilé    à sec  tion en double T dont l'âme est disposée horizonta  lement, le chariot 21 est de préférence commandé  automatiquement par un organe engageant la face  intérieure de l'aile correspondante.  



  Les     fig.    3a à 3h montrent les positions dans  lesquelles des profilés de diverses sections peuvent  être percés. Ces sections sont les suivantes  a) Section en double T avec âme en position hori  zontale.  



  b) Deux éléments à section en U, les branches cen  trales étant disposées l'une contre l'autre et hori  zontalement.  



  e) Section simple en U reposant sur les arêtes de  ses branches extérieures.  



  d) Deux sections en L disposées dos à dos et repo  sant chacune sur l'une de leurs branches.  



  e) Section simple en L reposant sur l'une des bran  ches.  



       f)    Section en T reposant sur l'aile.  



  g) Section en double T avec l'âme disposée verti  calement.  



  h) Section en U avec la branche centrale disposée  verticalement.  



  Chacun des organes palpeurs est relié à un indicateur  visuel 24. Ce dispositif est montré à la     fig.    4.  L'extrémité .supérieure de l'organe palpeur pré  sente une crémaillère 26 que entraîne un pignon 28       portant    une aiguille 30. Un cadran 32, en regard  duquel se déplace l'aiguille, est gradué en fonction  de la hauteur de l'extrémité inférieure de l'organe  palpeur, mesurée depuis le sommet des rouleaux.  La liaison entre le pignon et la crémaillère assure  une amplification d'environ 4 à 1.  



  Le cadran peut tourner autour de son axe d'un  angle équivalent à la moitié de l'épaisseur de la       partie    du     profilé    avec laquelle l'organe palpeur vient    en contact. Par exemple dans le cas d'une section  en double T reposant sur les arêtes de ses ailes, le  cadran peut tourner d'un angle équivalent à la moitié  de l'épaisseur de l'âme du profilé, de façon que  l'aiguille indique la hauteur du centre de cette âme  par rapport au support. La rotation du disque s'ef  fectue au moyen d'une vis sans fin 33 engrenant  avec les dents 35 du cadran ; cette rotation peut  s'effectuer manuellement ou automatiquement sous  la commande de moyens destinés à palper la dimen  sion correspondante de l'élément qui doit être percé.  



  Un petit moteur électrique 34 est utilisé pour  entraîner chaque organe palpeur 16 par l'intermé  diaire d'une vis sans fin de réduction 36 et d'un  pignon 38 qui engrène avec la crémaillère. Entre la  vis sans fin et le pignon est disposé un embrayage  non représenté susceptible de patiner et constitué par  une roue montée à frottement doux, ceci permettant  au moteur d'abaisser l'organe palpeur 16 sans exer  cer sur celui-ci une force trop élevé. La roue montée  à frottement doux peut servir aussi bien à abaisser  qu'à élever l'organe palpeur.  



  En fonctionnement, l'organe palpeur est main  tenu au-dessus du convoyeur lorsqu'un profilé à  percer est amené en position. Le profilé est ache  miné à sa position de perçage en entraînant les roues  du convoyeur et sa position longitudinale pendant  le perçage peut être déterminée par un arrêt (non  représenté) avec lequel le profilé est destiné à venir  en contact. Dans le cas de profilés dans lesquels  plusieurs séries de trous doivent être percées, il peut  être prévu plusieurs arrêts situés à différentes dis  tances du plan de symétrie des socles de perçage.  Dès que le profilé atteint la position dans laquelle  il doit être percé, il y est fixé et en même temps les  moteurs électriques 34 sont mis en action afin de  provoquer l'abaissement des organes palpeurs.

   Les  moteurs     tournent    le temps nécessaire pour amener  l'extrémité     inférieure    des organes palpeurs au niveau  du convoyeur, quand aucun profilé n'est monté sur  le convoyeur, mais dès que ces organes palpeurs  viennent en contact avec l'âme du profilé (dans le  cas d'un profilé de section en double T) les roues  montées à frottement doux commencent à patiner.  On lit alors les positions atteintes par les aiguilles 30  sur les cadrans 32 et la position     verticale    des     socles     de perçage peut être ajustée en conséquence. Les  moteurs électriques sont mis en marche en sens  inverse dès que la lecture a été faite afin d'élever  les organes palpeurs de façon que le profilé puisse  être déplacé sitôt le perçage terminé.

   Arrivés à  l'extrémité de leur course, les organes palpeurs  actionnent des interrupteurs qui     provoquent    l'arrêt  des moteurs électriques.  



  Les organes palpeurs<B>16</B> peuvent être agencés  de manière à commander la hauteur des forets de  manière que cette hauteur soit réglée automatique  ment en fonction de la hauteur de la face du profilé  qui coopère avec les organes palpeurs.



  Device for drilling rolled sections Steel structures usually consist of sections which are cut to the desired length in rolled sections and are then drilled so that they can be joined to other sections by rivets or bolts . To drill holes through the wings of the profiles, it is customary to place these profiles on a horizontal support and to drill at least part of the holes using one or more horizontal drills.



  To this end, the location of the holes to be drilled must be determined exactly with respect to one or more reference planes of the profile. For example, the positions of holes drilled in the wings of a double T section will be determined with respect to a reference plane passing through the plane of symmetry of the web. Given the tolerances accepted in this field, the reference plane may not be located at the desired height above the support and if the position of the drills is adjusted in relation to the height of the support, the holes made in the flanges will not be correctly positioned.

   In addition, a rolled profile may be slightly curved in a vertical plane, so that the height of the reference plane above the support may change unless means are provided to apply the profile downward along its entire length. way that it becomes perfectly rectilinear. These difficulties are well known and to avoid them, recourse has been had to various simple expedients such as the insertion of wedges between the support and the profile.



  The present invention aims to overcome these difficulties, and has for object an apparatus for drilling rolled profiles which is characterized in that it comprises a horizontal support, means for fixing the profile horizontally in position on the support, at at least one horizontal drill the position of which can be adjusted in height and at least one feeler member carried by a rigid frame and able to be lowered and raised relative to the frame so that it can register the height relative to the support of one side of the profile to be drilled placed on the support.



  The drawing represents, by way of example, an embodiment of the apparatus which is the subject of the invention. FIG. 1 is a schematic plan view. Fig. 2 is a tick diagram elevation view thereof.



  Fig. 3 shows profiles of different sections in their drilling position, and FIG. 4 is a detail view, partially in section, of the feeler member and of the indicator. The device shown in the drawing is capable of simultaneously drilling the two wings of a section 8 whose section is double T. It comprises two drilling bases 2 and 4 sliding horizontally and vertically and each carrying six horizontal drills 6 intended for pierce said wings.

   The profile 8 rests on a support constituted by a conveyor formed by controlled rollers 10. On each side of the drilling bases are arranged fixing members 12 and 14, the members 12 being fixed and the members 14 being able to be moved horizontally.



       As the two wings by which the section 8 rests on the support can have variable dimensions, the differences being able to vary from one wing to another and even be in opposite directions with respect to the theoretical dimension, the two bases of hole 2 and 4 can be adjusted independently of each other in the height direction in a known manner, not shown. To determine the deviations, two feeler members 16 are provided, each consisting of a vertical rod carried by a frame.

   The frame comprises a transverse bar 18 wppor- ted by pillars (not shown) extending on either side of the conveyor and situated in a plane parallel to the plane of symmetry of the bases but offset with respect to the latter. Thus the frame does not interfere with the drills. On the transverse bar 18 are mounted two carriages 20, 21, each of these having an arm 22 extending to the plane of symmetry of the bases and each carrying a feeler member 16.

   The feelers are located in the plane of symmetry of said bases and are intended to be brought into a plane close to that in which the corresponding wing of the section 8 is located. The carriage 20 is not adjustable, along the transverse bar. , that over a short distance to be able to take account of the differences in thickness of the wings and also of the presence of additional plates while the carriage 21 is adjustable over a large distance in order to be able to take into account profiles of different widths in the hori zontal sense.

   This adjustment can be done manually or automatically; in the case of a section section in double T whose core is disposed horizontally, the carriage 21 is preferably controlled automatically by a member engaging the inner face of the corresponding wing.



  Figs. 3a to 3h show the positions in which profiles of various sections can be drilled. These sections are as follows a) Double T section with web in horizontal position.



  b) Two U-shaped elements, the central branches being arranged one against the other and horizontally.



  e) Simple U-shaped section resting on the edges of its outer branches.



  d) Two L-shaped sections arranged back to back and each resting on one of their branches.



  e) Simple L-shaped section resting on one of the branches.



       f) T-section resting on the wing.



  g) Double T section with the web vertically arranged.



  h) U-section with the central branch arranged vertically.



  Each of the feeler members is connected to a visual indicator 24. This device is shown in FIG. 4. The upper end of the feeler member has a rack 26 driven by a pinion 28 carrying a needle 30. A dial 32, opposite which the needle moves, is graduated as a function of the height of the needle. lower end of the feeler member, measured from the top of the rollers. The connection between the pinion and the rack provides an amplification of about 4 to 1.



  The dial can rotate around its axis at an angle equivalent to half the thickness of the part of the profile with which the feeler member comes into contact. For example in the case of a double-T section resting on the edges of its wings, the dial can turn by an angle equivalent to half the thickness of the web of the profile, so that the needle indicates the height of the center of this core relative to the support. The rotation of the disc is effected by means of a worm 33 meshing with the teeth 35 of the dial; this rotation can be carried out manually or automatically under the control of means intended to feel the corresponding dimension of the element which is to be drilled.



  A small electric motor 34 is used to drive each feeler member 16 through the intermediary of a reduction worm 36 and a pinion 38 which meshes with the rack. Between the worm and the pinion is disposed a clutch, not shown, capable of slipping and consisting of a wheel mounted with gentle friction, this allowing the motor to lower the feeler member 16 without exerting too much force on it. . The wheel mounted with gentle friction can be used both to lower and to raise the feeler member.



  In operation, the feeler member is hand held above the conveyor when a section to be drilled is brought into position. The profile is brought to its drilling position by driving the wheels of the conveyor and its longitudinal position during drilling can be determined by a stop (not shown) with which the profile is intended to come into contact. In the case of profiles in which several series of holes have to be drilled, several stops may be provided located at different distances from the plane of symmetry of the drilling bases. As soon as the profile reaches the position in which it is to be drilled, it is fixed to it and at the same time the electric motors 34 are put into action in order to cause the lowering of the feeler members.

   The motors run for the time necessary to bring the lower end of the feelers to the level of the conveyor, when no profile is mounted on the conveyor, but as soon as these feelers come into contact with the web of the profile (in the case of a double T section profile) the gently friction mounted wheels start to slip. The positions reached by the needles 30 on the dials 32 are then read and the vertical position of the drilling bases can be adjusted accordingly. The electric motors are started in the opposite direction as soon as the reading has been taken in order to raise the feelers so that the profile can be moved as soon as the drilling is finished.

   When they reach the end of their travel, the feelers activate switches which stop the electric motors.



  The feeler members <B> 16 </B> can be arranged so as to control the height of the drills so that this height is automatically adjusted as a function of the height of the face of the profile which cooperates with the feeler members.
