1. , the Work transfer device of the continuous progressive die of a kind of multistation is characterized in that:

  • this device comprises intermittently synchronous drive mechanism, flexible synchronous conveyer band [1] and vacuum chamber structure;

    Intermittently synchronous drive mechanism is made of driving wheel [2], driven pulley [3] and indexing intermission mechanism, and driving wheel is connected with the punch press spindle drive by indexing intermission mechanism;

    Flexible synchronous conveyer band [1] is a ring-type, and its left and right two is supported by driving wheel [2] and driven pulley [3] tensioning respectively, forms upper and lower two planes, and the flat transverse level is located in the upper and lower intermode of punch press on the conveyer belt, as a workpiece conveyor surface [4];

    Surround around the counterdie of punch press workbench and be provided with a uncovered casing [5], the wall of casing [5] is provided with vacuum orifice [6];

    Described workpiece conveyor surface [4] covers the open-mouth of this casing [5], constitutes a vacuum chamber [7] with casing [5];

    This vacuum chamber [7] internal frame is provided with a supporting plate [8], and this supporting plate [8] sets off under workpiece conveyor surface [4], is provided with driving mechanism up and down around the supporting plate [8];

    Corresponding to mould, offer workpiece locating hole [9] on the flexible synchronous conveyer band [1], also offer circular hole [10] on the supporting plate [8].
