SWAGING-MACHINE.
Specification of Letters Patent.
PatentedDec.9,1919.
Application filed February 5, 1918. 'Serial No. 215,453.
To all whom it may concern:
. Be it known that I, Ronnnr smm HAY- DOCK, a citizen of the United States, residing at Oranford, in the county of Union and State of New Jersey, have invented certain 'new and useful Improvements in Swaging- Machines, of which the following is a specification.
The present invention relates to swaging In the so-called-rotary swaging machine there is a cage of rollers operating in a tool steel ring which rollers are brought to bear upon the back of hammers operatmg the swaging dies. From its deslgn 1t is evident that the rounded surface of the rollers comes in contact on one side with the tool steel ring and on the opposite side with the back of the hammer. This results in a line contact on both sides of the rollers, which when the work is heavy, in time crushes the material and frequent replacements are necessary.
' In the toggle type swaging machme the mechanism is such that all the crushlng force is communicated in a series of toggle jaws through phosphor bronze plns. These 1 pins must be made comparatively small for reasons of practlcablhty and wear out in a short time. Similarly all the other Wearing surfaces in the driving eccentric and rods and the jack shaft bearings require frequent replacements. l It is the object of this invention to pro,- vide a swaging machine in which the wear is reduced to a reasonably small amount and the period of its usefulness extended in proportion. Another object is to provide a swaging machine, simple 1n construction and operation, which has only a small number of elements subjected to the wear incldent to the heavy workof machines of this character. I
In carrying out the invention I have been guided principallybythe knowledge that wear is approxlmately inversely proporaspects my invention consists in translating.
mechanism interposed? between the power shaft and the swaging tools or dies, so con structed and arranged that the wear is distributed over a relatively large surface,
which is the principal wearing surface.
For a fuller understanding of the inventlon reference is had to the appended drawmgs in which Figures 1, 2 and 3 areplan view, side elevation and end view, respectively, of a swaging machine embodying the invention;
Fig. 4 a horlzontal section on line 4l4, of 1 1,21 2;
Fig. 5 a vertical section on line 55;
Fig. 6 a vertical transverse section on line 6'6 of Figs. 1 and 2; and Fig. 7 1s a view 1n side elevation of a modification of a detail.
In the drawings in which like numerals refer to like parts 1 represents the cast iron body holding the swaging dies 2. This body 1 1s preferably supported on cast- iron legs 3, 3" and 41, 4 which may be provided with holes 5 toreceive the usual foundation bolts (not shown). A convenient way of securing the body 1 on the legs is by means of studs 6 extending through the yoke 7, which interconnects the legs 3 and 3 and 4 and 4, into the body 1.
The body 1 incloses a working chamber 8 terminating in an enlarged portion 9.
Through this enlarged portion 9 extends a shaft 10 carrying at the outer end a cast iron fly wheel 11 which is fastened to theshaft by a forgedsteel key 12. The mounting for the shaftcomp'rises a bush 13 and phosphor bronze bearing bushes 14 and 15 in the bush 13 and the body 1 respectively. This arrangement represents merely conventional means for putting the shaft 10, which has an enlargement intermediate its ends, into or out of position.
The central portion of the shaft 10 has turned upon it an eccentric part 16 which has any desired eccentricity, according to the length of the stroke, say one inch. About this eccentric part 16 is loosely fitted a bronze collar 16 which in turn is fitted within a floating collar 17 preferably of steel.
The collars 16 and 17 may be held against lateral shifting by any suitable means as for instance by flanges 18 and 19 formed on the bushes 14 and 15 respectively; As the shaft 10 is revolved, the collar 17 is shifted through a distance equal to twice the eccentricity. This movement is communlcated to a machine steel plunger 20 whlch in turn communicates the movement to swaging dies 2.
The steel plunger is made of two parts, the front portion 20 and the rear portlon 21. The front portion has preferablya plane surface 22 to contact with the collar 17 and has preferably pivotal movement relatively to the rear portion. The oint between the two plunger parts 20 and 21 may be advantageously in the form of a radius 24 as indicated in Fig. 5. The plunger part 20 is normally held in central PPSltlOll by means of the steel liners 25 act ng as springs against the projections 26 1n the part 20. As shown in Fig. 5 the walls of the body 1 have slight recesses 25 ad acent the free end of the liners. This allows the front portion 20 of the plunger to accommodate itself when the pressure is applied through the floating collar 17 and always bring about a perfect surface contact.
located at opposite sides of the body 1, are
held at one end by steelscrews 29 and separated from the body by pipe spacersi30, and hear at their free ends upon pins 31 and 32 projecting from the plunger element 20. The tension on the springs 27 and 28 is adjusted by tension cap screws 33. having threaded engagement in lugs 3 1 projecting from both sides of the body 1, lock nuts 35 being provided to lock the screws in ad justed position.
The stroke of the plunger is adjustable to any variation from O to the total eccentricity of the shaft. For this purpose screws or studs 36 extend. into the body 1 and the bush 13 respectively and may be locked in any desired position by lock nuts 37. These screws are substantially in alinement with the pins 81 and 32 and form abutments therefor. The openings 38 and 39, through which the pins 31 and 32 project, are made of such diameter as to allow for the reciprocating movement of the pins toward and away from the collar 17.
Intermediate the last swaging die and the adjacent wall of the body 1 is inserted a wedge 40, as is customary,'to compensate for the wear. This wedge is held inadjusted position by locking plate 41 adjust- .ably secured to the body by a screw 42 and jam nuts 12. To facilitate changing the dies, the'machine is provided with a cast iron door 13 which also has a steel liner plate 25. This door-is hinged by means of a hinge pin 16 to the. hinge block 4A which in turnlis detachably connected to the body 1 by bolts 15. The door 48 may be locked by a suitable latch mechanism operated by a handle 43 (Figs. 2 and 3).
The machine maybe driven from a line shaft or an electric motor 17 may be mounted directly uponit, as shown. This electric motor is shown as driving a pulley 48, from which the fly wheel 11 is driven by a belt 19 running over an idler 52 for taking up the'slack. The shaft 5 5 of the idler 52 is mounted in a bearing 58 bolted to the body 1 by bolts 54.
The steel liners 25 are removably attached to the body 1 by means of screws 50 or in any other suitable: manner.
The machine is provided with the necessary oil passages, one being indicated at 51 leading into the enlarged portion 9 of the working chamber 8. This enlarged portion forms an oil well providing for the efficient lubrication of the floating collar and its of contact with the steel floating ring 17 for the larger portion of the revolution of the shaft 10. During this period the floating ring revolves with the shaft, but when the eccentricity of the shaft is sufiicient to bring the floating ring 17 in contact with the plunger 20, the friction between these two pieces causes the ring 17 to cease revolving with the shaft. This condition continues during the stroke. Atthe end of the stroke the floating ring17againleaves the plunger plug and rotates again with the shaft. This action of alternately revolving about the shaftand rotating with it causes the floating ring to always resent a new surface to the plunger plug. l3y this continuous creeping movement of thefloating ring the wear is uniformly distributed over the whole surface thereof. 7 r
The combined cam. and hammer stroke thus obtained is particularly effective for the purpose indicated. p p
In order to swage aptube. rod or the like, the operator inserts the end of the particular article vinto the appropriate die and pushes it forward at the endof each swaging stroke. r
While I prefer to makethe surface 22 of theplunger plug20 plane, it may be more or less curved. e V a The plunger, which is shown in Fig. 5 as composed of two parts fitted together on a half-circle, may be advantageously made as shown in Fig. 7. The body of the plunger may be made of the desired length, then bored to provide cylindrical surfaces 60 and 61, whereupon thebody may be cut in two parts 20. and.. 2 1. .A-shaft 62 may then be interposed between the two parts and 21' to fit the surfaces 60 and 61. This shaft may be provided with a bore to receive a pin 63 similar to pins 31 and 32 in Fig. 4.
In this way the two component parts of the plunger 20 and 21 are interconnected by a radius joint in a mechanically simple manner.
