Definitions

  • ABSTRACT A forging machine including an anvil for supporting an object to be forged for impact by means of a dropping head.
  • the anvil is supported by springs and an absorption means is situated below the anvil to absorb shocks thereof and prevent transmittal of vibrations to the surroundings of the machine.
  • the absorption means is separated from the anvil by a predetermined separation and is resiliently mounted.
  • This invention relates to a forging machine comprising an anvil against which a dropping head is dropped an absorption part.
  • the foundation mass is large in size and volume, the mass is placed below the floor surface.
  • the masses are supported elastically by inserting a layer of elastic material both between the body and the foundation mass and between the foundation mass and the ground.
  • the dropping head, the anvil and the lower part of the body and the foundation mass are thus constructed with a three-mass-vibrating system during forging, supported entirely upon the large foundation mass.
  • the heavy and voluminous foundation mass results in several drawbacks, such as that the forging machine cannot be easily moved once mounted, and, also that such a device is expensive.
  • An object of the invention is to provide a forging machine, which eliminates the necessity of a large foundation mass having a double action mass moved synchronously with the dropping head whereby movement of the anvil is, however, effectively prevented without vibrations being detrimentally transmitted to the surroundings of the machine.
  • this object is attained by situating the anvil adjacent absorption part, which is separated from the anvil for absorption of shacks.
  • This absorption part is preferrably the approximate size of the anvil and may be directly supported on the body of the machine by means of springs. Due to the relatively small mass of the absorption part of the invention the relative speed and acceleration to produce a shock and the range of movement are considerably higher than the corresponding values of prior art forging machines having a foundation mass.
  • the construction according to the invention is most effectively achieved when the anvil and the absorption part do not contact with each other at rest. They are placed at a predetermined distance from each other, their contact surfaces are split or separated by a predetermined distance. The impact of the element has thus been arranged to occur in two phases which is particularly advantageous in relation to vibration of the anvil.
  • the size of the split or separation between the contact surfaces of the anvil and the absorption part is most important just after the time that the dropping head has contacted the work piece creating impact of the anvil against the absorption part.
  • By using the split or separation and also a proper mass ratio between the absorption part and the anvil it is possible by means of the construction according to the invention to decrease the amplitude of movement of the anvil to an amount to equal the separation the rest between the anvil and the absorption part at rest. Because of the short contact time of a few hundredth of second between the dropping head and the work piece or anvil, the journey made together by the dropping head, the work piece and the anvil remains short, so that the size of the separation required is small and the movement of the anvil is slight during the same.
  • FIG. 1 is a side view of the fundamental drawing of the forging machine according to the invention
  • FIG. 2 shows the principle of the mutual location of the masses in the forging machine according to the invention.
  • drive equipment 1 lifts the dropping head 2, and then sinks and strikes work piece 4 situated on the anvil 5 which is in turn is supported on body 3 by spring 6.
  • the dropping head, the work piece and the anvil being supported by means of the springs 6 on the body 3 move together the small distance 10 between an absorption 7 part and the anvil.
  • the dropping head rebounds upward at a certain speed and the drive equipment lifts the dropping head. to the position preceding the shock. Influenced by the energy of motion obtained from the dropping head, the work piece and the anvil strike the absorption part 7 which in the state of rest is biased against stop ill by springs 8. Influenced by the shock caused by the anvil, the absorption part is moved downward, until stopped in a lower position by springs 8 and a viscous absorption means for dash pot 9,.
  • the size of the separation between the anvil and the absorption part is assumed to be of the size of the extent of movement made by the anvil during the first pushing phase. In principle, this separation may be larger, but it will then always resuit in a larger amplitude of the anvil, which is harmful regarding forging.
  • Theoretic determining of the most advantageous split distance is difficult, but by practical experiments it may, however, be determined with sufficient accuracy and its size varies usually between 1 and 3 mm.
  • a forging machine is of course not confined to the above-described example of an embodiment, and the mutual location and manner of support such as of the dropping head, the anvil and the absorption part may considerably differ from the above-mentioned embodiment. Accordingly, all other embodiments are possible within the scope of the following claims.
  • a forging machine comprising an anvil mounted for movement in response to an impact and for supporting an object to forged
  • an absorption part mounted adjacent the anvil to absorb shocks resulting from the impact of the anvil and dropping head, said absorption part being separated from the anvil at a rest position by a predetermined separation and said anvil adapted to move a distance equal to said predetermined separation in response to the impact of the dropping head to impact against the absorption part for absorption of shocks.
