Abstract

The invention discloses a fine-blanking hydraulic machine which comprises a stand column, an upper cross beam, a lower cross beam, a main oil cylinder and a moving beam, wherein the upper cross beam is arranged at the upper part of the stand column, and the lower cross beam is arranged at the lower part of the stand column; the main oil cylinder is arranged on the lower cross beam, and the moving beam is connected with the main oil cylinder and driven by the main oil cylinder to do up-and-down reciprocating motion; a guide mechanism used for controlling the direction of motion of the moving beam is arranged between the lower cross beam and the moving beam. The moving beam realizes the independent guidance through the guide mechanism, so that the stand column no longer assumes the guiding function, and the guiding accuracy of the moving beam cannot be influenced by the deformation of the stand column caused by working load; meanwhile, the processing requirement of the stand column can be significantly reduced, and the processing cost is reduced. Moreover, the structure of the moving beam is more compact, so that the rigidity of the fine-blanking hydraulic machine can be increased. The fine-blanking hydraulic machine is suitable for industrial fine blanking and can also be used for a fine blanking technology experiment.

Further, described guiding mechanism is the fit structure of guide pillar and guide pin bushing.
Further, described sill is provided with the base for installing master cylinder, and described guiding mechanism comprises the guide pillar being located at base and the guide pin bushing being located at dynamic beam, and described guide pillar coaxially stretches into guide pin bushing and can along the axially-movable of guide pin bushing.
Further, described dynamic beam and base are all arranged in the region that column, entablature and sill enclose.
Further, at least arrange two described guide pillars, any two described guide pillars are symmetrical set.
Further, four described guide pillars are set altogether.
Further, at least arrange four described columns, any two described columns are symmetrical set.
Further, four described columns are set altogether.
Further, described entablature and sill are equipped with corresponding pilot hole, and described column is connected with pre-load nut through after pilot hole.
Further, described dynamic beam is provided with the adpting flange for being connected with template.
Beneficial effect of the present invention: essence of the present invention rushes hydraulic press, dynamic beam realizes independent pilot by guiding mechanism, column is made no longer to bear guide function, the distortion of the column caused by service load can be made no longer to affect the guiding accuracy of dynamic beam, also significantly can reduce the processing request of column simultaneously, cut down finished cost; And the structure of dynamic beam is more compact, can improve rigidity of the present invention; The present invention is not only suitable for industrial fine-edge blanking and uses, but also can test for fine dies technology.
