Definitions

  • a known forging press comprises a machine frame which rests on cast-iron slideways. which are firmly connected to the foundation. That sliding-surface bearing arrangement has the great disadvantage that it permits of a longitudinal movement of the underframe but cannot oppose at all any bending stress on the underframe.
  • the underframe is firmly fixed to the foundation at one point.
  • the bending moments which are due to the forging operation and which load the base frame can be transmitted to the foundation.
  • These bending moments tend to lift the centrahportion and to depress the end portions of the base frame. This tendency is opposed by the fixation at one point and by the points of bearing support.
  • there is no resistance opposing any elongation of the underframe because the underframe is fixed in the middle of its length and this portion is not involved in an elongation which is directed from said fixed point to both ends of the base frame. and because the remaining points of support permit of a longitudinal displacement of the underframe relative to the foundation.
  • the means provided according to the invention for mounting the underframe can take up bending moments and longitudinal elongations without involving a high expenditure.
  • the underframe or the like rests at the points of bearing support on slide plates, which consist preferably of self-lubricating plastics material. and is held down by foundation bolts fixed to the foundation.
  • the slide plates present a low frictional resistance to a longitudinal movement of the underframe and the foundation bolts yield resiliently to accommodate said movement.
  • the foundation bolts ensure a snug engagement of the underframe with the slide plates so that a satisfactory transmission of the vertical components of force from the underframe to the foundation is also ensured. All other components of force will be taken up by the machine frame itself.
  • slide bearing plates taper in thickness in a direction which is transverse to the longitudinal direction of the underframe and are connected to adjusting screws or the like which bear on abutments that are fixed to the foundation. These adjusting screws then permit in a very simple manner of the levelling of the machine frame and of a readjustment of slide bearing plates which have become worn.
  • longitudinal guides for the underframe or the like which guides are disposed adjacent to the terminal points of bearing support.
  • These longitudinal guides may also be provided with slide bearing plates so that they do not present a substantial frictional resistance to a longitudinal movement of the base frame.
  • the fixing means comprise a cross-shaped horizontal member. which has a lower part that has a flaring inverted U-shape in cross-section and is embedded in the foundation. and an upwardly protruding upper part. which fits a mating groove in the underframe.
  • the cross-shaped lower part is provided at each arm with at least one T-head bolt for fixing the underframe. and the head of said bolt has end faces which mate the inclined flanges of the U- shaped cross-section.
  • the fitting upper part permits of a definite fixation of the center of the underframe relative to the foundation and the T-head bolts cooperating with the lower part of the cross-shaped member ensure a rigid fixation of the central portion of the underframe to the foundation because the tightening of these bolts results in a holding down of the underframe and in an expanding of the lower part in the foundation.
  • FIG. 1 is a side elevation. partly in section. showing a forging press according to the invention.
  • FIG. 2 is a top plan view showing the fixing means.
  • FIGS. 3 and 4 are transverse sectional views taken on lines III-III and lVIV in FIG. I. i
  • the forging press comprises a horizontal machine frame 1, in which two mu-' tually opposing press rams 2 are mounted. which are horizontally movable.
  • the machine frame 1 is carried by an underframe 3, which is longitudinally mounted on a foundation 4 so as to be longitudinally slidable relative thereto except at fixing means 5. by which the underframeis fixed in the middle of its length to the foundation 4.
  • the underframe rests on the foundation so as to be movable relative thereto at points of bearing support 6, 7. At these points of bearing support.
  • the underframe 3 rests on slide plates 8, which are covered with self-lubricating plastics material 8'. and is held down by foundation bolts 9 embedded in the foundation 4.
  • the slide bearing plates 8 present a low frictional resistance to a sliding movement of the underframe 3 and the foundation bolts 9 can bend resiliently to accommodate a displacement of the underframe.
  • the slide bearing plates 8 taper in thickness in a direction which is transverse to the longitudinal direction of the underframe and are .connected to adjusting screws 10. which bear on abutments 11 that are fixed to the foundation. By means of these adjusting screws and 'the tapered slide bearing plates. the base frame 3 can be exactly levelled and any wear of the slide bearing plates 8 may be compensated. To avoid a distortion of the underframe 3 in the longitudinal direction and to define ex.-
  • longitudinal guides 12 are provided adjacent to the terminal points of bearing support 7.
  • Each of these longitudinal guides consists substantially of a guide block 13, which is fixed to the foundation 4' by means of T-head bolts 14 and has a guiding portion 15. which is slidable in a longitudinal groove 16 of the underserted in the foundation 4.
  • That cross-shaped lower part 19 has-a flaring inverted U-shape in cross-section and is provided at each of its arms with a T-head bolt 20 for fixing the underframe.
  • the head 21 of said bolt has end faces 22, which mate with the inclined flanges of the U-shaped cross-section.
  • the cross-shaped-member.'18 has an upwardly protruding part 23, which fits a mating cross-shaped groove 24 in the underframe 3 so that the fitting part 23 immovably locates the center of the underframe and the latter can be firmly fixed at this center by means of the cross-shaped member.
  • the T-head bolts 20 are tightened so that the underframe is depressed and owing to the inclined en'd faces 22 of the T-heads 21 and the flaring cross-section of the lower part 19 the cross-shaped member is expanded in the foundation.
  • the means provided according to the invention for mounting the underframe on the foundation constitute a simple structure which is capable of accommodating the longitudinal elongation which is due to the forging forces and of transmitting to the foundation the forces and bending moments resulting from the forging'ope'ration unless said forces and moments are taken up by the machine frame.
  • a forging press which comprises a horizontal machine frame.
  • bearing support means for supporting portions of said understructure which are remote from the center ll) of its length on said foundation to permit of a sliding longitudinal movement of said portions relative to said foundation.
  • bearing support means comprise terminal bearing support means disposed near the ends of said understructure and longitudinal guides are provided, which are adapted to be fixed to said foundation adjacent to said terminal bearing support means and serve to guide said understructure in its longitudinal direction.
  • cross-shaped member having a cross-shaped lower part adapted to be fixed in said foundation and a 30 cross-shaped upper part adapted to protrude upwardly from said foundation and fitting said groove.
  • said lower part has a flaring inverted U-shape in cross-section and comprises. four arms. each of 35 which has inside lateral surfaces and is provided with at least one screw fixed to said understructure and having a T-head contained in said arm. said head having inclined end faces in mating contact with said inside lateral surfaces of said arm.
