Definitions

  • ABSTRACT A forging machine including a frame supporting a reign Applkd'mn Prmmy Data dropping head to impact an anvil wherein the frame is May 26, R972 hnland l48l/72 Supported on a f d i by Springs Vibrations ated by impact of dropping head and anvil are dissi- 52 us.
  • the forging machine of the copending application includes a damping mass which is, separate from the anvil, and is moved in a damped manner in consequence of a blow by the anvil wherein the optimum size of the damping mass is approximately the same as the anvil mass.
  • Other prior art machines also includes a large foundation mass under the frame which-is dug below the floor'surface to reduce the vibrations caused by the blows of the ram block of the customary forging machines in their environments. Between theframe and the foundation mass and between the foundation mass and the ground, there is a layer an elastic damping material the prior art.
  • Such constructions are also known in whichelasticity has been brought about by means of springs. It is characteristic of the prior machines of this construction that the forging machine itself has been supported on the foundation mass. Because of this, it has been-necessary to keep the suspended motion of the foundation mass small so as not to make forging work difficult, while'the anvil is moving together with the frame of the machine and the foundation mass. With a certain energy of blow received by the foundation mass, the springing motion is dependent onthe size of the mass. Because of this a smallamplitude of motion correspondingly causes in these constructions a very great increase of the mass. Although the prior art machines can significantly vibrations, the foundation mass is large and expensive and consumes a great deal of space.
  • a specific object of this invention is to bring about a further improved forging machine, in which by means of the mutual placing and v support of the masses, the highest possible utilization degree and versatility of the masses has been effected. Accordingly, the mass of the forging machine of invention in its whole has essentially been concentrated to the functionally effective masses, i.e. the anvil, ram
  • the anvil mass is supported on the frame of the forging machine, to which the ram block mounted by means of bearings.
  • the frame is supported with springs on the stationary foundation, while the damping mass is placed in the hole situated in the foundation and/or in the opening of the anvil.
  • FIG. 1 is a schematic side illustration of a first embodiment of the forging machine of the invention
  • FIG. 2 is a schematic side illustration of a second embodiment of a forging machine of invention.
  • the ram block 1 has been supported on the frame 2a with bearings, to anvil 2b 'is affixed on frame 2a in stationary fashion.
  • the masses of elements 2a and 2b can accordingly be considered functionally as one mass and which is called here the anvil mass.
  • the upper part of the frame 2a forms a closed circle, which encloses the ram block 1.
  • a damping mass 3 is mounted in separate relationship from the anvil mass 2a, 2b, but interacts functionally therewith.,
  • the frame 2a has been suspended on the sta tionary foundation 7 with the springs 4, whose stiffness depends on the size of the anvil mass 2a, 2b and more.
  • the springs 4 have to be of a stiffness to resuit in the specific frequency of the mass system is sufficiently greater than the blow frequency of the ram block.
  • the blow length of the springs 4 can be very small.
  • the damping mass 3 has also been supported on the stationary-foundation by means of the springs 5, whose stiffness on the contrary is small in comparison 7 to springs 4 and blow length large.
  • the optimum size of the damping mass 3 is approximately the same or even a little smaller than that of the anvil mass 2a, 2b.
  • a damper 6 is also situated between the stationary damping mass 3 can freely move with a large amplitude of motion.
  • frame 2a can be provided with a recess 9, which receives part of the damping mass 3.
  • the forging machine itself can extend above the floor,
  • FIG. 2 there is illustrated another embodiment of the forging machines of the invention, which differs from the forging machine presented in FIG. 1 in regard to the location and support of the damping mass 3.
  • the damping mass 3 been placed entirely within an opening 9a situated in the frame 2a, which is surrounded by the anvil mass in the form of a closed circle.
  • the damping mass 3 is supported on the frame 2a by means of the springs 5.
  • the anvil mass 2a, 2b and the damping mass 3 are situated relative to stationary foundation 7 ing machine types.
  • the function of the forging machine of the embodiments of FIGS. 1 and 2 in accordance with the invenin this embodiment in reverse order to customary forg tion is the following.
  • the work piece to be forged is supported by the anvil 2b.
  • a driving device (not shown) lifts the ram block 1, which when dropped strikes the work piece.
  • the blow energy of the blow is' transferred through anvil 2b and frame to the damping mass 3.
  • Damping mass 3 under the influence of the blow moves downwards and is damped by the damper 6 to retain to its original position by resiliency of the springs 5.
  • the construction in accordance with the invention is unexpensive, it does not require much space and can easily be moved from place to place. Moreover, uncompli-- cated construction guarantees the safety of operation.
  • the construction in accordance with the invention can also be utilized in customary forging machines as a subsequent solution, in which case the frame with anvil and ram block previously built upon a large foundation mass the is supported with springs directly on the stationary foundation. A and damping mass in accordance with the invention has been placed under the frame in a hole previously made in the foundation.
  • a forging machine comprising a frame adapted to be supported on a foundation
