Definitions

  • the invention relates to a forging hammer with bear guide, in a bear carrying a tool between stands is moved back and guided on the uprights by means of guides is where each guide is attached to the stand adjustable Guide bar and one cooperating with this, on the bear provided reworkable Bär-guideway has, from the Bear material is formed, and at the Bear Guideway at one bear end a first Betzbahn FIFA and the other Bachede forms a second Betzbahn compassion.
  • the bear is after a certain number of operating hours refinished on the continuous bear guideways, to eliminate the crowning.
  • reworking is the projecting center area of the continuous bear guideway ablated.
  • the number of operating hours after which a post-processing the continuous Bear Guideway is required considered too low.
  • An object of the invention is, therefore, a forging hammer of the type mentioned above, in which a Balligwerden the bear guideway is avoided and the operating hours, after a reworking of the bear track is required, is enlarged.
  • the forging hammer according to the invention is this Solving task, characterized in that the bear guideway limited to the two end Bärbahn Publishede is that delimit a lead-free bear area between them, in which the bear material is reset against the Bärbahn pieces is.
  • the forging hammer according to the invention is a log bear, in which in the guide-free Bear area or the middle area the bear material "omitted", e.g. relative to the remaining Bärbahn pieces is finished.
  • the frequency of bear reworking and that reduced conditional downtime is the frequency of bear reworking and that reduced conditional downtime.
  • the center area recessed between the two Bärbahn pieces makes e.g. at least one third of the bear length and in the Usually at least half the length of the bear. Especially useful and it is advantageous if the end near the tool Bärbahn rave is longer than the other end Betzbahn friendship. The forces caused by eccentric loading are better the two Betzbahn unanimouse distributed.
  • the invention Blacksmith hammer usually designed as a drop forging hammer, the tool carried by the bear is a die.
  • the threading aid is the guide strip arranged so that the bear at the time of the actual Even the Einfädel silk not claimed.
  • the threading aid ensures a highly accurate guidance of the bear and prevents the tool far away Bärbahn yoga the Immersion in the stand strikes against the guide rail.
  • the Threading aid which is an auxiliary guiding device, forms guide slope, about which the tool distant Bärbahn proteins the guide rail of the stator is supplied.
  • the forging hammer according to FIGS. 1 and 2 has a frame which two stands 1 forms, which are connected by a transverse part 2 below are and wear an attached crosshead 3 above.
  • the crosshead 3 applies the space located between the stands 1 a Free space recess 4 too.
  • the cross member 2 carries an anvil 5, which is equipped with a tool, not shown. Between Stand 1 is a bear 6 arranged on the anvil 5 facing Side is equipped with a tool 7.
  • the bear is 6 carried on a rod 8, which projects into the crosshead 3.
  • the bear 6 is shown in FIG. 2 on each of the two stands 1 of two Guided pairs of guides 9, each pair - in cross-section seen - to one of the two border areas of the bear or the Stands shifted towards and inclined to a central axis is arranged.
  • Each guide 9 comprises a guide rail 10, which is mounted on the stand 1 by means of a not shown, but known per se adjustable.
  • the guide rail 10 extends over the essential Part of the length of the stand 1 in one piece.
  • Fig. 3 shows schematically a bear 6, with one side of a guide rail 10 is assigned.
  • the bear has one over the length continuous bear guideway 15, with the guide rail initially limited a gap 16 game.
  • This gap increases continuous throughout its length about a wear gap 17, which is adjustable in a central region 18. It continues to form in the end regions 19 a reinforced wear gap 20, so that the continuous bear guideway overall a convex History 21 receives.
  • each guide 9 on Stand 1 a in two guide rail parts 21, 22 divided guide bar on, with the guide rail parts independently are adjustable. It is therefore intended that in each case the leadership 9 on the stand 1 of two separately adjustable guide bar parts 21, 22 is formed, one of which is the tool 7 distant Betzbahn Gla 11 and the other the tool associated Betzbahn Gla 12 is associated.
  • Fig. 4 also illustrates a bear-side track piece 14a of the threading aid 14th
  • the forging hammers according to drawing is also provided that with forward-moving, beating bear 6 Einfädel Anlagen 14th free from the bear, i. free from a beating bear conditional mechanical load is.
  • the Einfädel Anlagen leads the Bear no longer, if that the tool distant Bärbahn Published in the dipped on the stand mounted guide rails.
  • Fig. 5 and 6 is a short bear with a particularly short stand realized.
  • the tool 7 far away Bärbahn Gla 11 is moved forward bear 6 in one position located not far from the forming area 23 than the tool 7 near Bärbahn Anlagen 12 when moved back Bears.
  • the retreating bear is in the position of Impact readiness.
  • Figs. 5 and 6 also illustrate a design in which the the Tool 7 distant Betzbahn Gla 11 of the Bär-Fparbahn outside the plane which is the Betzbahn biology 12 close to the tool extended, lies. This allows the bear to make low, when the height-to-width ratio is made larger. It is also provided that the tool 7 distant Betzbahn with 11th the Bär-Flickbahn one of the Betzbahn supra close to the tool 12, e.g. has a different shape in cross-section.
  • the bear 6 has a compared to the embodiment according to FIG. 1 modified form in its upper part. Also here have the Tool 7 distant Bärbahn Sharing 11 and / or the threading aid 14th circular cross-section.
