PUNCHING MACHINE.
Application med July s, 1922. serial No. 573,573.
ychines and has for its object the provision of a machine carrying or embodying a plurality of selectively usable dies' and punches co-operating therewith, means being provided wherebyany selected punch may be engaged 'by an operating plunger.
An important object is the vprovision of a device of this character in which the punches and dies are always in line ready for' use without adjustment. f Still another object is the provision of a device of this character in which the proper dies `are always in association with the proper punches, selection of the desired punch and die being accomplished by rotary movement of theadie and punch carrier.
Still another object is the provision of a machine of this character which is provided with novel lever operating means for actuating the plunger so that great power may be exerted for punching metal sheets of any gauge.
fAn additional object is the provision of a device of this character which will be comparatively simple and easy to manufacture, simple to operate, efiicient and durable in service and a general improvement in the art.
With the above and other Vobjects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which: f
Figure 1 is a side-elevation of the device,
Figure 2is an elevation taken at right angles to Figure 1,
Figure 3 is alongitudinal vertical section showing one of the punches as moved downwardly, 4
Figure 4; is a horizontal section looking down upon the die carrier,
Figure 5. is a horizontal section looking down upon the punch carrier,
Figure 6 isa detail elevation of the track.
Figure 7 is a detailelevation looking at the edge ofthe plunger and showing the manner of shiftingthe punches,
Figure 8 is a detail perspective view of one of the dies,
Figure 9 is a detail of the punches.
Referring more particularly to the draw ings the numeral 10 designates the base of the machine from which rises a U-shaped frame 11 within the open portion of which is mounted the punching mechanism to kbe perspective view of one described. The lower arm 12 of the frame` is 'bifurcated and mounted within the bifurcation is a bearing 13 within which is rotatable a vertical shaft 14 upon which is keyed or otherwise secured the die carrier designated broadly by the numeral 15.
The die carrier is formedk as a disk 1G provided with a pluralityof holes 17 within which are detachablj7 engaged the dies 18 which are held in place by set screws 19 or the like. The dies are here shown as formed with anges 20 which engage the top of the disk and operate to prevent the dies from slipping down out of place.
The upper end of the shaft 14; is journaled in a bearing 21 yon a bracket 22 which is secured against the inside of the `vertical portion of the frame 11 and located below this bracket is an interrupted circular track 23 supported by an arm 24 secured thereto and to the bracket 22, and furthermore supported by a pair of brackets or arms 25 which are secured to the upper arm 26 of the frame and to the track at the sides of the opening 27 therein. n
The track 23 is formed of two sections 23 and 23b which have their meeting ends preferably extending diagonallyL as shown. Rivetedv upon the underside of the section 23" is a plate member 23c which u'nderlaps the'section 23a and vwhich is bolted thereto by means of a bolt 23d.
Keyed upon the shaft 1/1 is the punch carrier which consists of a disk 28 formed with openings 29 through which are slidably mounted punches 3() located above and cooperating with the corresponding dies y18. At their upper ends these punches are formed with reduced necksl and heads 32. The punches are supported in inactive posi tion by the engagement of these heads upon the track 23.
Slidable through the upper arm of the frame is a plunger 83 which has its lower end carrying jaws 34 adapted to engage the punches for effecting operation thereof. Each end of the upper arm of the frame carries an extension, one being designated by the numeral 35 and the other by the numeral 36. Pivoted upon the extension 35 is a lever 3T which is pivotally connected with the upper end of the plunger 33 by links 38 and `this lever has its free end pivotally con* nected by links 39 with the operating lever 4() which is pivoted upon the extension 36.v
The numeral 4l designates a stop member which is hinged upon the top of the upper arm of the frame and which isengageable beneath the lever 37 for holding all the parts in inactive position. y
The operation is as follows: The operator rotates the punch carrying disk and the die carrying disk 16 and 28 together as a unit to brinF the desired punch below the plunger 33. llVhen the punch carrier is rotated the punches are of course carried around with it and the heads 32 thereof ride on the'track 23. The jaws 34: carried by the plunger substantially lill the opening 27 inthe interrupted track so that the heads of the punches will ride over these jaws when passing the interruption in the track. Rot-ation is continued until the desired punchfhas its head disposed between the jaws of the plunger. The material to be punched is then laid over the corresponding die 18 and the operator then grasps the lever 40 and presses it down which will result in downward movement of the plunger. As the plunger moves down, the lower and thereof will engage the top of the head of the selected punch and force the punch down into co-acting relation to the associating die. `When the lever is subsequently moved upwardly the punch carrier may be rotated to bring a different punch into active position but it is to be noted that such cannot of course occur until the plunger is elevated to the point where the jaws constitute means for filling the interruption in the trackway.
A distinct feature of advantage is that in case a punch becomes broken or needs to be replaced or any other reason bolt 23d may be removed to effect removal of t-he track section 23b so that the punch may be easily taken out without interfering with any of the other parts of the mechanism.
From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply construced and consequent-ly inexpensive punching machine which is quickly and easily adjustable or shiftable to permit use of any selected one of a large number of punches. It is likewise to be observed that the punches and dies are always in alignmentJ so that there will be no possibility of improper action. It is if course apparent that the device will be a great time and labor Saver so as'to be a manifest improvement over the ordinary machines of this type. Owing to the s implicity of the construction and the fewness ofthe parts it will be apparent that there is very little to get out of order so that the device should have a long life and satisfactorily perform all of its functions.
lVhile l have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the'right to make -such changes in the form,
construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.
