Definitions

  • This patent relates to the field of iron and steel plants and particularly regards equipments for the casting in a die by means of a press.
  • this patent deals with a new press provided with a top assembly which shifts in order to facilitate the replacement of the forging die .
  • die-forging presses for the casting at low pressure are known, these die-forging presses are assembled over the bedplate in which the forging die is lodged by means of proper stanchions.
  • an holding furnace, from which the metal to be casted is taken, is lodged.
  • Said lay-out of the various components allows the casting at low pressure to be carried out optimally obtaining, in this way, perfect workpieces.
  • the die has to be replaced so as to produce different workpieces using the same equipment, press and holding furnace, it is necessary to act sideways by means of machines such as forklift trucks which take and insert the various dies sideways, between the vertical structure supporting the press, that is, in the narrow space between the bedplate and the lower plane of the press.
  • the dies are fixed in the right position thanks to proper fasteners.
  • the new plant consists in its main parts of an elevated bedplate on which the die is fastened and under which the holding furnace is positioned, a vertical structure comprising four vertical pillars supporting upper two guide rails or horizontal parallel slides, a press unit assembled on a cart horizontally shifting.
  • the supporting vertical structure consists of four pillars fastened integrally to the bedplate. On the upper part of said pillars a couple of guide rails or horizontal parallel slides are fastened, joining the tops of the couples of pillars.
  • Said guide rails or slides project on one of the two sides of the vertical structure for a lenght which is greater than the half distance between the two vertical pillars.
  • a movable plane slides horizontally from a central position with respect to the four pillars and the die to a sideways position.
  • the movable plane supports the various parts of the press that is the sliding cylinders, the operating piston(s) and the press.
  • Some hydraulic jacks or other proper devices make the movable plane shift along the guide rails or slides.
  • the new plant constituted like that allow an easy replacement of the die.
  • Each couple of guide rails or slides are provided for being divided in two hinged parts so that their ends can rotate sideways the structure itself so as to reduce the laterally bulk when the plant is working.
  • the movable plate with the press unit can shift onward or on the right or left side according to the different needs and the different spaces available.
  • An improvement consists of using the shifting press unit as lifting device, and for removing and laying the die.
  • the press unit and particularly the pressure plate, are equipped for hooking and supporting both parts of the die, that is the lower part as well.
  • a plane whose height is comparable to the face of the die, or a translating plane, or a lift truck which is placed side by side.
  • the press unit dips down closing the two parts of the die which are joined with pins or hooks preset in the execution phase of said die.
  • the lower part of the die is released from the bedplate to which it was integral and the press unit raises lifting the whole die.
  • the press unit shifts sideways along the guide rails or slides and dips down on the fastened plane or on the shifting plane or on the lift truck leaning on the die which is later released from the pressure plate of the press unit.
  • the following die is positioned in the same discharged position of the previous die and is fastened to the pressure plate of the press unit.
  • the press unit shifts over the bedplate and dips down leaning the die on said bedplate.
  • the lower part of the die is fastened to the bedplate, the pins and the hooks joining the two parts of the die are removed, and each part of said die is now fastened the former to the bedplate and the latter to the pressure plate.
  • Figure 1 shows a side view of the plant in which it is possible to see the holding furnace (1), the bedplate (2), the die (3), the fixed pillars (4) of the vertical supporting frame, the guide rails or slides
  • Figure 2 shows the moment in which the die (3) is replaced, the moment in which the press unit (6) assembled on the movable plane (not visible in the figure) is shifted along the guide rails or slides (5) and the crab (7), with its hook, takes or places the die (3).
  • Figure 3 shows a schematic frontal view of the plant in which it is possible to see even the plane (8) shifting on the guides rails or slides.
  • Figure 4 shows a plan view in which is visible how the guide rails or the slides are divided in two parts (5.1, 5.2) of which the projecting part (5.2) can rotate in order to reduce the bulk when said guide rails or slides are not necessary.
  • Figures 5 and 6 show how it is possible to couple the whole die (3) with the press unit (6), said press unit shifting sideways, takes the die (3) to be removed on a lateral plane (9, figure 5) or on a lift truck (10, figure 6).
  • figure 5 shows how it is possible to apply quickly a new die (3) while the previous is being removed by means of a lift truck.

Abstract

L'invention concerne une nouvelle presse hydraulique de coulée à basse pression, comprenant un ensemble (6) de presse monté sur un plan qui peut coulisser horizontalement sur deux rails ou patins (5) de guidage solidaires de la structure de support verticale, de manière à rendre la région surmontant la matrice (3) accessible depuis le dessus. Le déplacement de la matrice par un chariot ou une grue (7) est ainsi rendu plus aisé. Les rails ou patins de guidage qui se prolongent au delà de la structure de support de l'ensemble de presse peuvent pivoter horizontalement et verticalement afin de réduire l'encombrement de la presse. L'ensemble de presse coulisse latéralement portant toute la matrice devant être enlevée et pose cette matrice sur un plan (9) fixe, un plan coulissant ou un chariot (10) élévateur se trouvant à proximité. Une nouvelle matrice peut alors être mise en place soit au moyen de l'ensemble presse qui reçoit la matrice depuis le plan latéral ou le chariot élévateur latéral, soit à l'aide d'un chariot qui peut poser la matrice sur le plateau amovible pendant que l'ensemble de presse enlève l'ancienne matrice.
