Definitions

  • the workpieces prior to their rolling must be free from defects, i.e. that particularly surface cracks extending more or .less deep must be prevented to a sufficient degree. This is effected in that the workpiece prior to its rolling is scanned or inspected in one way or another in respect of cracks, which thereafter are re- • moved by grinding. At present, this surface condition ⁇ ing is carried out substantially for one or two sides of the workpiece at a time in a separate machining station where the workpiece is reciprocated beneath a machining head, or the machining head is reciprocated over the workpiece.
  • the invent ⁇ ion has the object to provide a grinding method and a
  • O ⁇ P ⁇ « device therefor by which continuous grinding of a workpiece is rendered possible, i.e. the grinding can be carried out on the continuous cast material after the casting but prior to the dividing into workpieces when the continuous cast strand is fed through the grinding machine.
  • the hot grind ⁇ ing directly on the strand a surface conditioning without disturbing interference in the production chain is obtained.
  • the higher workpiece temperature at the grinding reduces the risk of crack formation, the cutting speed can be kept higher at a lower effect, the production capacity is increased, and better work- piece surfaces can be obtained. Owing to the lower effect required for the grinding, also the wear of the grinding wheels is reduced.
  • the grinding mach ⁇ ine When the grinding mach ⁇ ine is made an integral part in the casting process, as described above, it does not cause any energy loss ⁇ es from the continuous cast material.
  • the total energy losses thus, decrease, which implies that the sub ⁇ sequent heating preceding the rolling can take place more rapidly, which additionally contributes to a corr ⁇ ect and thereby less expensive plant.
  • the cutting members are arr ⁇ anged overlapping for each surface on the workpiece, so that either the entire surface of the workpiece ' can be machined or alternatively the separate units can be controlled separately for spot machining during the continuous feed of the workpiece through the grinding station.
  • the grind ⁇ ing station comprises a plurality of grinding modules, each with a grinding spindle axle substantially perp ⁇ endicular to the respective surface of the strand, i.e. the grinding wheel almost in parallel with the surface. Due to the overlapping arrangement, the entire surface of the strand can be ground during the passage of the workpiece through the grinding station.

  • Each grinding mod ⁇ ule comprises a substantially vertical spindle 3 driv ⁇ en by a motor 6 via an axle 5 provided with splines, and on each spindle a grinding wheel 1 is mounted.

Abstract

Une machine à meuler, est destinée en particulier au meulage à chaud en continu de pièces à usiner coulées (2) pendant leur transport entre leur moulage continu et leur laminage ultérieur. La machine comprend un support (1) sur lequel sont fixées plusieurs unités de meulage, dont les roues de meulage (1) sont distribuées de sorte qu'elles couvrent ensemble toute la largeur des surfaces des pièces à usiner respectives que l'on désire meuler. A chaque support de meulage, un moteur (6) est relié à un arbre cannelé (5) avec une broche de meulage (3) mobile dans une enceinte (11) de broche. La roue de meulage (1) est fixée sur cette broche (3). A l'aide d'un piston hydraulique (9), le mouvement de la broche de meulage et par conséquent le mouvement de va-et-vient de la roue de meulage, et donc la pression peuvent être réglés. La force du cylindre hydraulique (9) dans le sens de la pièce à usiner est ajustée de préférence en commandant effectivement la roue de meulage de manière à obtenir un accouplement et un désaccouplement en douceur de la roue de meulage lors de l'usinage de la pièce à usiner (2).
