Coiled tube mfr - by a high-performance machine employing two drive shafts |
摘要 |
<p>Machine for the mfr. of coiled tubes has two drive shafts with toothed sheels which co-operate with notched shafts to constitute a roller-bending device. The first drive shaft has a toothed tappet and a second toothed wheel and is associated with a power cylinder of a locking bolt to ensure the axial alignment of the first drive shaft with the first bending roller. The second drive shaft has a tappet which reciprocates with the tappet which carries an eccentrically mounted axle with the second bending roller and a toothed wheel. The latter co-operates with the second toothed wheel of the first drive shaft and has a projection on which a crank is mounted and in which a guide-piece is positioned in association with a gudgeon carrying the first bending roller. The crank is linked to the toothed wheel of the second drive shaft by a power cylinder of a locking mechanism on the crank.</p> |
