Definitions

  • each column necessarily comprises at one of its extremities a nut for its fixing on to one of the bed pieces and at its other extremity a hydraulic cylinder the surface of which bears on the other supporting bed or beam of the press.
  • the multiplicity of the columns usually arranged side by side in two rows and in each row at a minimum distance one from the other which is imposed by the necessity either of screwing their xing nuts or of placing their hydraulic cylinders one alongside the others, leads to considerable dimensions of the bed or supporting pieces, and to the disadvantage that, the longer the bed pieces become (that is, as the number of columns becomes greater), the greater are the shearing forces and deiiecting moments which these pieces must withstand.
  • the present invention relates to a hydraulic press of great power in which the principal members are made. arranged and distributed in such a manner as to permit the maximum reduction of their dimensions and consequently of their weight, as compared with the corresponding dimensions and weights of a press of the same 4o power constructed according to the usual methods.
  • Figure 1 is a front view
  • Figure 2 is a corresponding plan view
  • Figure 3 is a vertical section on the broken 15 line III-III of Figure 2
  • Figure 4 is a horizpntal section on the line IV-IV of Figure 3 and shows a detail of construction.
  • l indicates the lower iixed 20 4 ties to the xed bed l, each of them comprising to this end a collar 3 and a fixing nut 4 arranged below the said bed and bearing against the latter. 35 At their upper parts the columns 3b pass freely through the movable bed 2 which they guide during its movements.
  • the even columns of the row (2nd and 4th), indicated by ah, are, cn the contrary, nxed to 40 the movable bed 2 and comprise to this end, like the columns of the uneven row, collars 3 and xing nuts 4 arranged above the said bed and bearing on its upper face.
  • column comprises is arranged at the extremity of the latter opposite to that which is xed to one or the other of the beds l and 2.
  • Each of the presses is constituted by a cylinder 6 and a piston 1, between which the liquid under pressure is admitted through a conduit 6a.
  • the cylinder B is movable with respect to its column along which its guiding piece 6c is adapted to slide, and also with respect to the piston l which is screwed to the end of the said column.
  • the outer end 6d of the guiding piece 6c abuts against the surface of the bed l or 2 corresponding thereto, and thus transmits to the latter the effort of the press.
  • Each guide 6c has a length greater than the length of the nut-carrying extremity of the co1- umn or columns adjacent thereto, which alone permits of bringing the columns of the saine row closer together, since the space occupied by the guiding parts 6c is less than that of the press cylinders 6.
  • the guiding parts 6c instead of being constituted by complete cylinders, are reduced to two tongues, leaving between them two gaps facing the nuts l of the adjacent columns as shown in Figures 1, 2 and 4.
  • the pressure of the liquid causes the sliding down of the piston I which carries with it the corresponding column 3h. which, in lits turn, also carries the movable bed plate 2 in the direction towards the lixed bed I. f
  • auxiliary hydraulic return cylinders 8 for example to the number of two, intended to move the bed 2 back to its original position after each compression stroke.
  • the hydraulic cylinders B may be supplied simultaneously with water under pressure in such manner as to cause. the press to exert its maximum total eilort, or only a reduced number of the said cylinders may be supplied so as to reduce in the same proportion the total .eiort of the press. ⁇
  • a hydraulic press comprising a ixed bed.
  • each of said columns being fixed at one end to one of said with its opposite end adaptedto cause said beds to approach one another, said columns being xed alternately to the xed and movable beds and having their hydraulic cylinders correspondingly positioned adjacent the movable and xed beds alternately and staggered axially with respect to the xed ends of the adjacent columns, whereby the length of said row of columns and the size of said beds may be reduced to a minimum.
  • a hydraulic press comprising a fixed bed, a movable bed, and a plurality of columns connecting and extending through bothof said beds, each of said columns having an enlarged head xed to one end thereof and abutting one of said beds, a piston connected to its opposite ends and a hydraulic cylinder associated with said piston and interposed between the latter and the other of said beds in thrust transmitting relationship movable and xed beds, whereby the spaces between adjacent columns and the size of said beds may be reduced to a minimum.
