- Application filed m 1922. Serial No. 578,059.
To all whom it may concern:
Be it known that I, SIMON BERG, citizen of the United States, residing at Detroit, in the county of WVayne 'and State of Michigan, have invented certain new and useful Improvements in Machines for Sizing Tub ing,- of which the following is a specification. I
This invention relates to a machine for swedging or sizing, tube. The object of the machine is to eliminate any irregularities in formation and to accurately size the tubing to the desired diameter. 1 r
The improvement herinafter claimed resides in the cage construction. The cage is made from a single casting and a retaining plate and. so designed that it will take the shocks of the hammer blocks and hammer block rolls without untimely wear. A cage of this construction will last very much longer than the ordinary cage construction.
In the drawings, F l is a vertical cross section of a swuging machine showing the rotor. and rol1- er cage in elevation. 1 Fig. 2 is a longitudinal section of the same, taken on the line 2-2 of Fig. 1. r
Fig. 3 is a rear view of the cap plate that is bolted to the roller cage. Fig. 4 is a side elevation of the rotor. Fig. 5 is a side elevationwof the cage casting. v
a'designates the housing of the machine in which is contained a cageb. This cage is made up of a ring 0 which is a single casting and the cap or end plate Z. This casting is formed with a plurality of roll sockets 6 having rounded ends f. The rolls 9 fit into the open ends of the roll sockets and protrude through the ring at either side as shown at j and i in Fig. 1. i
The cap plated is secured tothe end of the cage ring by'the cap screws k, dowel pins on fit into the dowel pin holes. This platehas machined thereon inwardly projecting bosses n that fit into the roll socket and serve to locate and hold the ring firmly to the end of thecasting.
The rotor p is provided with a cross slot y in which slide the hammer blocks 1- and the two dies 8. When the rotor is revolved and a tube a lies between the dies, the hammer blocks 6 are causedto reciprocate due to striking the rolls 9. This reciprocates the ets, and'means for retaining the rollers -atdies and forces them upon the tube thereby hammering the tube down to size and accu-. rate configuration.
Each of the rolls 9 is provided. with a f l rounded and tapered inner end which fits into the rounded end of the roll socket,
The ends ofthe roll sockets are somewhat spaced from theend of the'casting so as to form a-heavy web at this'p'lace-so'as-to take-the thrust and wear. Theidea of mak ing this end of the cage a heavy solid casting in place of a plate, very materially adds tothe strength of the cage, resists wear;
and breakage much longer than acage con structed in the ordinary way with a sim ple plate at this end of the cage. Furthermore it permits the use ofa'spherical end socket and a roller with a rounded end.
This construction is better adapted to-take the thrust of the rollerwithout; undue,
wear-. s 7 V 7 What I claim is: c
1. In a machine for the purpose specifled, the combination of a cage in the form i of a ring casting solid at one end and provided with a plurality of open-ended, opensided roll sockets, rolls contained "in said sockets anda plate provided with inwardly projecting bosses for fitting into the ends of the roll sockets and remo'vably secured to the open end ofthe ring casting. V
2..In a machine for the purpose speci fiedya. cage comprising a solid end casting. provided Wltl1.-0IJ6I1-S1Cl6d, open-ended rollsockets having at their innerends a rounded conformation, hammer block rolls rotatably supported 1n said sockets and provided at their inner end with rounded ends for engaging the rounded ends'of the roll sockthe open ends in the ring casting. V 3. In a machine for the; purpose sp"eoi-' fied, a cage comprising a solid end ring provided with'open-ended, 'open-sided roill sock j" ets having at their inner ends substantially 7 e provided with rounded inner ends supported 5 spherical configuration, hammer block rolls in said roll sockets and a retainingplatere movably secured to theopen end ofthe'ring' casting and provided with inwardly-ping" I jecting'bossesprojecting into the inner ends of the said sockets.
" In testimony whereofl aifix my'signatu're.
