Abstract
Apparatus for separately adjusting the shut height of individual tools on a progressive forging machine "on the fly" when the machine is running. The apparatus includes individual load bearing wedge blocks on the slide for supporting associated tool cassettes. Each wedge block is displaced by a secondary wedge-like cam driven by an associated power actuator. The wedge geometry yields a compact, rugged construction. The cassettes are supported by precision located surfaces that allow desired axial adjustment without loss of alignment with opposed dies.
Claims9
In a progressive forging machine having a die breast and a slide that reciprocates towards and away from the die breast, the die breast and slide having a plurality of opposed aligned work stations for carrying cooperating tools, power operated mechanism for adjusting each tool on the slide axially in a direction parallel to the direction of slide movement independently of the axial position of the other tools and maintaining the lateral alignment of a tool being axially adjusted with the associated opposed tool, a tool support at each work station on the slide, each tool support being located by precision located surfaces, said surfaces being in planes parallel to the axial direction of the work station, said tool support being in the form of a tool holder cassette and said slide including a power operated clamp for clamping said tool cassette thereon, and wherein said machine includes a separate load bearing block associated with each work station on the slide.
A progressive forging machine having a die breast and a slide that reciprocates towards and away from the die breast, a plurality of opposing work stations on the slide and the die breast, a separate load bearing block on the slide associated with each work station, a tool support in the form of a tool holder cassette axially located on each slide work station in lateral alignment with reference to an axial direction parallel to the direction of slide movement with respect to an opposed die work station on the die breast, power operated means for separately adjusting the axial location of each of said load bearing blocks and the associated tool support cassette, locating surfaces for precisely positioning the tool support cassette at each work station so that it is in alignment with an opposing work station on the die breast and being arranged to permit axial adjustment of the associated bearing block and tool support cassette while maintaining the alignment of the tool support cassette relative to its opposed die breast work station, and a device to automatically clamp each load bearing block and the associated tool support cassette in an adjusted position, and wherein said machine includes a separate load bearing block associated with each word station on the slide.
