Inštrumentovaný prípravok na experimentálny výskum ťahania rúr pozostáva z hornej, strednej a dolnej časti. Horná časť obsahuje upínaciu objímku (1) a rotačný upínač (2) s axiálnym valčekovým ložiskom (3). Do rotačného upínača sa upína ťahaná rúra (5) prostredníctvom závitovej tyče (4). Stredná časť obsahuje nosník (6), ťažnicu (7) v držiaku (8), závitové upínacie tyče (9) a matice (10). Dolná časť prípravku pozostáva z držiaka tŕňa (11), tŕňa (12) upnutého na závitovej tyči (19) tŕňa, kosouhlého ložiska (13), tlačnej pružiny (14) a meradla (15) sily. The instrumented jig for experimental research of pipe drawing consists of an upper, a middle and a lower part. The upper part comprises a clamping sleeve (1) and a rotary clamp (2) with an axial roller bearing (3). The drawn pipe (5) is clamped into the rotary clamp by means of a threaded rod (4). The central part comprises a beam (6), an axis of gravity (7) in a holder (8), the threaded clamping bars (9) and the nuts (10). The lower part of the jig consists of a mandrel holder (11) clamped on a threaded rod (19) of the mandrel (12), an angular bearing (13), a compression spring (14) and a force gauge (15).
