Definitions

  • the invention relates to a column guide frame according to the preamble of claim 1.
  • the pillars are connected to a first plate and guided in guide bushings of the second plate. If the tool located between the plates is to be accessible from three sides, the columns are arranged along a longitudinal edge at two corners of the plates. If such a frame is eccentrically loaded or used in an inaccurately operating press, then the disadvantage arises that the guide columns jam with the guide bushes, which is due to canting between the columns and the bushings as a result of the play between the columns and bushes. In order to mitigate this effect, it is known to design the guide bushes as long as possible. However, the effect achieved is low and the height of the frame is increased. However, the aforementioned jamming cannot be ruled out.
  • a further measure consists in arranging the columns in the center on a line of symmetry of the frame, whereby, however, the tool located between the plates is accessible from only two sides. Another measure is to provide the columns on a diagonal at two corners of the plates. The stress exerted by the tool on the column guide can be transferred to the column guides in an evenly distributed manner, however tilting, particularly in the case of inaccurately operating presses, cannot be excluded. The same applies if four columns are provided which form a rectangle when viewed from above.
  • the task is to design the column guide frame in such a way that jamming of the column guide does not occur when the load is off-center.
  • the column guide frame according to FIGS. 1 and 2 has a first plate 1 and a second plate 2.
  • first plate 1 On the first plate 1, two guide columns 3, 4 are attached in a conventional manner, which run rectangular to the planes of the plates 1, 2 and parallel to each other. These guide columns 3, 4 are guided in guide bushes 5, 6 on the second plate 2, which are embedded in this plate 2.
  • the guide columns 3, 4 with the guide bushes 5, 6 are located in the area of the corners 7, 8 along the longitudinal edge 9 of the plates 1, 2.
  • a tool located between the plates 1, 2 is accessible from the two narrow sides and from the longitudinal side opposite the long side 9, but the frame is loaded with its guides off-center.
  • a third guide column 10 is provided centrally between the guide columns 3, 4, which is fastened to the second plate 2 and is guided into a guide bushing 11 of the first plate 1.
  • the frame according to FIGS. 3 and 4 shows the same guiding principle.
  • Two strips 12, on which the frame rests, are connected to the first plate 1.
  • a back part 13 is screwed to these strips, the plate 1 being screwed between the strips 12 and the back part 13.
  • An upper part 14 is screwed to the back part 13 and runs parallel to the plate 1.
  • the columns 3, 4, which are screwed to the upper part 14 and the strips 12, run between the upper part 14 and the strips 12.
  • These columns 3, 4 support the second plate 2 via the bushes 5, 6, which runs parallel to the plate 1, in order to prevent the guides from jamming and thus jamming, the plate 2 carries the third guide column 10, which is in the bushing 11 the first plate 1 is guided.
  • the upper part 14 carries a drive motor 15, with which the plate 2 can be moved up and down.
  • a tool is arranged between the plates 1, 2.
  • the columns 3, 4, 10 with their bushes 5, 6, 11 are arranged along the rear part 13.
  • the columns 3, 4 are arranged on a diagonal 17 in the area of the corners 8, 16.
  • the second plate carries the guide column 10 in the area of the corner 7, which is guided in the guide bush 11 of the first plate 1.
  • a fourth guide column 20 is provided in the area of the corner 19, which, like the guide column 10, is carried by the plate 2 and is guided in a guide bushing of the first plate.
  • the columns 10, 20 thus lie on a further diagonal 18 of the rectangular plates 1, 2.
