19/09/7170 455229? M1 car Patented Nov. 13, 1934 v UNITED STATES PATENT OFFICE UPSETTING MECHANISM Application September 9, 1932, Serial No. 632,364
1 Claim.
This invention relates to new and useful improvements in upsetting mechanism, particularly to means for upsetting a workpiece at an angle to its axis. Reference is made to application of applicant, Serial Number 193,649, May
It is the object of this invention, among other things, to provide a simple, efiicient and positive means for actuating the punch slide relatively to the gate, whereby the rectilinear path of movement of the gate and that of the punches on the punch slide will produce, during the working stroke of the gate, an angular motion of a punch mounted on the slide, such movement being derived through parts associated with the mechanism which gives the punch slide transverse movement of the gate. A further object of the invention being to design and construct such mechanism that it may be readily applied to upsetting or heading machines of the conventional type with the minimum labor and expense.
In the drawing, wherein similar parts are similarly indicated;
Figure l is a transverse sectional elevation of an upsetting machine or header of the conventional type, having my improved mechanism associated therewith;
Figure 2 is a fragmentary elevation thereof;
Figure 3 is a sectional view, taken generally 3.iupon line 33 of Figure 2, of the connection arms, cams and adjacent parts; and
Figures 4. and 5 are side elevations of the cams, through which motion is transmitted to the connection arms.
In upsetting machines, headers or the like, the punch slide has a straight line reciprocatory movement transverse to that of the movement of the gate. In the means herein disclosed the punch slide, in addition to its usual movement jrelative to the gate, has a timed independent movement, whereby during a working stroke of the gate the rectilinear path of movement of the gate and that of the punch carrying member will produce an angular motion of a punch on i fijjthe punch carrying member. In this invention such independent movement is derived in part from the same positively actuated means that imparts the reciprocatory movement thereto.
In the drawing, 10 indicates the body of an 9jupsetting, heading machine, or the like, 11 the gate which has a reciprocatory movement thereon, 12 the punch slide, 13 the punch holder, 14
and 15 the punches which are held within the punch holder, 16 a shaft rotatably mounted in having thereon companion blocks 1'7, each of which slides within a slot 18 in the connection arms 19. Also journaled in the body 10 or the like, is the rock shaft 20, having a crank arm 21, through which is a slot 22. The connection arms 19 are pivotally connected with the crank arm 21 through the stud 23, bushings 24 and nuts 25. This stud is movable toward and away from the axis of the rock shaft 20 and secured in any of its adjusted positions through the threaded sleeve 26 and lock screw 27.
The cradle 28 forms part of the rock shaft 20 and slidably connected therewith is the foot plate 26, which moves in said cradle so that as the punch slide 12 travels in the same path as and with the gate, it also reciprocates thereon in a path at substantially a right angle to the axis of the punches.
The necessary rocking movement of the shaft 26 is acquired from the earns 30 and 31 fixed on the shaft 16 and having contact respectively with the cam rolls 32 and 33. Through these cams the connection arms are actuated positively in both directions. As shown herein the lower or second punch 15 is the punch that completes the angular heading ofthe workpiece and moves in a path, while in contact with the workpiece, at an angle tothe axis of the latter. This punch performs its function, upsetting operation, when the punch slide is in its approximate up position and during the independent movement of the punch slide. cam 30 with a projection 34 thereon and the cam 31 with a depression 35 therein, these being located on the cams so as to be diametrically opposite each other. Thus, when the connection arms 19 are moved forwardly, that is, to the left, as shown in Figure 2, each of the rolls 32 and 33 rides on the periphery of their respective cams until the roll 32 is opposite the depression 35, at which time said roll rides into said depression and the roll 33 onto the projection 34, thus drawing the connection arms 19 rearwardly a limited distance, depending upon the depth of the recess and height of the projections. This gives a slight independent movement of the punch slide at a time when the punch 15 is in contact with the workpiece and through the rectilinear path of movement of the gate produces a relative angular movement of the punch 15 for an angular heading operation. The continued rotation of the cams causes the cam rolls toride out of the depression and ofi the projection and the punch slide continues in a straight line movement again,
Such movement is derived by the until the next cycle of operations gives it the independent movement described.
Recognizing that certain modifications in the details of my invention are possible, I do not limit myself to the construction exactly as shown and described, but claim all that falls fairly within the spirit and scope of the appended claim.
What I claim as new is:
In an upsetting mechanism, in combination, a gate adapted to be reciprocated toward and from a work piece; a punch carrier movably carried by the gate, punches carried by the carrier, means for actuating said carrier, said means including a drive shaft, cams on said shaft, a pitman operated by said cams and operatively connected gate, said short movement combined with the gate movement producing an angular movement of said carrier and punch, said indexing cam being so contoured as to allow such short movement.
