Definitions

  • Such presses are often of a type including a pair of yokes, separated by a pair of uprights and surrounded by a girdle built up from prestressed steel strip.
  • a pair of yokes separated by a pair of uprights and surrounded by a girdle built up from prestressed steel strip.
  • the present invention relates to stands for high pressure presses, the stands of which have to absorb very high forces or stresses.
  • the size of the conventional stand is limited by the piece weight of the steel parts that can be produced by steel manufacturers.
  • the fit between the constituent parts, especially the yokes and uprights, is of such a close nature that the parts have to be machine finished. Owing to this the size of the stand is limited not only by the piece weight of the constituent parts, but also by the possibility of machining these parts.
  • the uprights may also be built up from sections in face to face relationship.
  • Stands according to the invention can be made several times larger than has hitherto been possible, as the piece weight now limits only the size of the constituent sections of yokes and uprights, but not the total size of the assembled yokes and uprights.
  • a stand according to the invention is easier to erect, and smaller lifting and auxiliary apparatus can be used owing to the comparatively low piece weight of the constituent parts.
  • An essential advantage as compared with the conventional stands is that if E.G. a crack develops in a constituent part this part alone is damaged.
  • a decisive advantage is that the invention ensures considerably higher values of mechanical strength for the stand as a whole through the yokes and uprights being composed of sections which can be given higher mechanical strength than an undivided upright or an undivided yoke.
  • the specific strength of steel material decreases with growing dimensions and conversely increases with declining dimensions.
  • FIG. 1 is an elevation of one form of press stand
  • FIG. 2 is a section on the line IIII of FIG. 1 illustrating a first embodiment of the invention
  • FIGS. 3 to 5 are views similar to part of FIG. 2 showing alternative embodiments of the invention.
  • Each of upright sections 2A is of sufficient cross-section thickness to permit it to support more than one of the yoke sections 1a.
  • FIG. 6 is a section on the line VI-VI of FIG. I;
  • FIG. 7 is a view similar to FIG. 6, showing a modification
  • FIGS. 8 and 9 are elevations similar to part of FIG. 1 showing modified forms of stand to which the invention may be applied.
  • a stand for a high-power press is constructed of two semi-cylindrical yokes l, separated by two orthogonal uprights 2.
  • a saddle 3 is provided along the outward curved surface of the yoke, and each upright is provided on the outside with a spacing plate 3a.
  • a girdle 4 is provided along the saddles 3 and spacing plates 3a.
  • the girdle is composed of steel strips wound round the yokes and uprights and prestressed as described in the Swedish and German patent specifications mentioned above.
  • the girdle is laterally bounded and supported by bracket plates 5, which are supported by pairs of posts 7.
  • the posts 7 are in their turn secured in position, on the one hand, by screws 13, screwed into the saddles 3 and the spacing plates 30, and, on the other, by bolts 12 with nuts, which bolts interconnect the posts 7 of a pair.
  • Each yoke 1 is composed of sections la (see FIG. 2), formed as semicircular plates having two flat opposite faces in parallel planes.
  • each upright 2 is composed of sections 2a, formed as rectangular plates having at least two opposite plane sides parallel to each other (see FIG. 6).
  • Each of upright sections 2a is of sufiicient thickness to permit it to support more than one of the yoke sections la.
  • the yoke sections 1a which build up to the yoke 1, (see FIG. 2) are held together by a plurality of bolts 6 with corresponding nuts, the bolts being passed through aligned holes formed in the yoke sections la.
  • a groove is formed in the inward flat face of the yokes l, and a corresponding groove is also formed in the adjacent face of the upright.
  • the groove in the yoke combines with the corresponding groove in the upright to form a recess, which can receive a bolt 6a.
  • Each bolt 6a is provided with nuts, and the guiding and assembling of the yoke and upright is effected by the co-operation between the bolts 6a, their nuts and the corresponding recesses.
  • the bolts 6a and the corresponding nuts have the effect of holding the yokes and the uprights together.
  • FIG. 3 A useful variant of a yoke is shown in FIG. 3.
  • the yoke l is here composed of semicircular discs or plates 1b of comparatively small thickness so that at least three and as many as six are supported on each upright section 2a.
  • the yoke is outwardly bounded by support plates 10.
  • the discs 1b and the support plates are held together by joining means, which may consist, for instance, of bolts 6 with nuts.
  • Guide grooves are provided in the same way as has been described above with reference to FIGS. 1 and 2.
  • the yoke is composed of semicircular discs la having two opposite sides in parallel planes, spaced from each other by spacing blocks 10 and spacing pieces 11, so as to form gaps 9 between the discs la when the nuts of the retaining bolts 6 have been tightened.
  • the total thickness of two discs la and associated spacing block 10 and pieces 11 is equal to that of a single upright section 2a.
  • An equalizing plate 8 is provided to absorb and distribute the forces which act from below upon the inner part of the yoke.
  • FIG. 5 Another useful variant is shown in FIG. 5.
  • a yoke is composed, or built up, of semicircular discs 1d separated by gaps 9, which are produced and fixed by spacing blocks 10 and spacing pieces 11.
  • the discs (plates) have two opposite plane faces, but as FIG. 5 shows these faces are not strictly parallel but converge in the direction of the girdle 4.
  • each upright 2 can be assembled, or built up, from upright members or sections 2a of rectangular cross section.
  • the yokes l have been composed of semicircular sections la, lb, 10, 1d. It may, however, be desirable from the point of view of mechanical strength to increase the height of the yokes in relation to their structural length or length between the points of support. This can be effected within the scope of the invention by forming the yokesin the way shown in FIG. 8.
  • the yokes 1A are composed of semi-elliptical or substantially semi-elliptical prisms.
  • the yokes 1A may be constructed of sec tions, analogously to the variants which are shown in FIGS. 2, 3, 4 and 5, and it will be appreciated that the constituent sections of the yokes have a semi-elliptical or substantially semi-elliptical shape.
  • An increase in the height of the yokes relatively to their strpctural len can also be effected withi t e scope o the mven on by using the form of em 1- ment shown in FIG. 9.
  • the part of the constituent sections or plates of the yoke 1B which lies above (and below respectively) a plane passing through the bolts 6a may here be semicircular, semi-elliptical or substantially semi-elliptical as described above.
  • every section or disc (plate) has a flap-shaped part 14 projecting under (and over respectively) the aforesaid plane.
  • a stand for a press comprising a pair of opposed yokes, a pair of uprights interconnecting and supporting the yokes, and a girdle surrounding the yokes and the uprights: the improvement that the yokes and uprights each comprise a plurality of separate sections arranged in face to face relationship and that more than one of said yoke sections is supported by the same upright section.
  • a stand as claimed in claim 1, comprising opposed grooves formed in the yokes and uprights, the said grooves co-operating to complete recesses, and bolts passed through the said recesses.
  • yokes each comprise a pair of outer sections of relatively thick section and a plurality of inner sections of relatively thin cross section located between the outer sections.
  • a stand as claimed in claim 1 comprising saddles located between the girdle and the yokes, bracket plates laterally supporting the girdle, and posts secured to the saddle, the said posts providing lateral support for the bracket plates.
  • a stand as claimed in claim I in which the yoke sections are in the form of semicircular discs.
