Abstract
662,443. Rolling annular bodies ; tube expanders. L' OUTILLAGE ROTAX. Jan. 7, 1949 [April 22, 1948], No. 509/49. Class 83 (iv). In a machine for drifting and chamfering holes in plates, or expanding and flaring tube-ends in the holes, of the type comprising a rotary tubular body 5 housing expansion and flaring rollers 9, 10, urged outwards and rotated by an axially displaceable taper pin 13, the tubular body 5 bears upon and is rotatable without axial displacement in an abutment member 3 and presents an abutment for an adjustable stop 25 carried by the taper pin 13. The rotary body 5 has interchangeable heads 6 screwed therein for drifting and chamfering different sized holes and carrying two slightly tapered expansion rollers 9, two conical flaring rollers 10, and a third expansion roller 9a longer than the rollers 9 and arranged so that it flattens out the ridge produced between the rollers 9 and 10. Interchangeable heads for expanding and flaring the ends of tubes in the holes are similar to the heads 6 but carry flaring rollers 10, each having an annular groove for flanging the ends of the tubes over the edges of the holes. Slots 8, Fig. 2, for the rollers have a width at the outer periphery less than the diameter of the rollers which are held in the slots at the inner periphery by projections 12 on a bush 11 inserted in the head 6. The pin 13 has an opposite and equal taper to the rollers 9 so that the rolling edges produce a non-tapered bore as the pin is moved forward and rotated. The pin 13 carries an adjustable stop nut 25 having an integral sleeve and buffer ring 23 and an intermediate thrust bearing 28 attached thereto by a threaded sleeve 24. The nut 25 is locked on the pin 13 by a lock nut 27 at a predetermined position such that the buffer ring 23 engages the end of the body 5 and prevents the pin 13 from moving further forward. In a modification, a stop nut 25 and lock nut 27 only are used, the stop nut being notched to engage a notch on the end of the body 5. In this case the pin 13 has a left-hand thread so that as the pin 13 continues to be rotated it will be screwed outwards in the stop nut 25 and retracted from the tubular head.
