Machine for drawing high tensile profiled wire - has small diameter working rollers running free between large diameter back up rollers

摘要

The machine is used for drawing high tensile profiled wire. It comprises a box frame contg. upper and lower rollers, the wire being pulled between grooves in the working rollers and reduced to the required section. Each working roller is of small dia. and is held between straight shoulders on a pair of back-up rollers retained in the valley between them. The back-up rollers rotate in bearings, one set being in a fixed lower block. The upper set rotates in a movable block and the gap is adjusted by a screw mechanism. Change-over is effected by changing the working rollers.
