THOMAS A. GORMAN, OF J'OHNSTOWN, PENNSYLVANIA FORGING IMAGHIIQ'F Application filed November 7, 1824. Serial No. 748,363.
To all whom it may concern: I
Be it known that I, THOMAS A. GonMiiN, 'a citizen of the United States, and resident of Johnjtown, in the county of Cambria and shaft 5 is journaled in suitable bearings adacent the rear end of the frame 2 and is connected by gears 6, and 7 with a power shaft 8 journaled in' bearings 9 and receiving 60 power through gears 10 and 11 from an electric motor 12.. i
The crank shaft 5 is connected by a connecting rod 13 with the cross head 3 so as to reciprocate said cross head, and a side 65 5 State of Pennsylvania, have invented certain ew and useful Improvements in Forging Machines, of which the following is a specification.
This invention relates to forging machines and more particularly to continuous motion or automatic forging machines for making ballsand other similar articles from round bar stock.
Heretofore balls such as made by the im-' proved machine of this invention have been made by power hammers or by an automatic machine costing thousands of dollars more than the presentmachine, and even with this expensive automatic machine the maximum output was considerably less than they outpu of the machine of this invention. This invention-has for its object the modification of a standard Ajax heavy dutyheading machine, such as is well known and commonly used in the art for heading heavy bolts and the like, so as to form-balls for use in crushing and grinding cement and other such material.
In the drawings- Figure l is a top plan of a forging machine embodying my invention.
Figure 2 is a side elevation thereof.
Figure .3 is an enlarged fragmentary plan showing the .hall forming mechanism.
Figure 4 is a sectional elevation on the line IVIV of Figure 3. v I
Figure 5 is a sectional'elevation on the line VV of Figure 3.
Figure 6 is a fragmentary sectional elevation showing the shear blade, receiving block and stock gage.
Figures 7 8 and 9 are'sectional elevations on the line VII-VII of" Figure 5, showing the machine in various forging positions.
In view of the fact that the Ajax heading machines are well known in the art and also since the novel features of this inventionmaybe used with other similar machines, the lieading machine will not be shown or described in detail.
dteferring more particularly ,to the drawings, the numeral 2 designates the main frame of the machine as a whole, which is provided with suitable guieleways for a lon- 'gitudinally movable-cross head 3 and a transversely movable side ram'l. A crank arm, designated generally by the numeral 14, is ecentrically mounted on one end of the crank shaft 5 and is connected to the side ram through a lmuckle system 14 so as to reciprocate said ram transversely of the frame 2.
A breast plate 15 is mounted in the forward end of the main frame 2 and is recessed to receive a combined stationary shear and die block 16. The plate 15 and block 16 are provided with a suitable opening 17 through which the bar stock is adapted to be fed by a suitable automatic feed mechanism =18, and the block 16 is further provided at a point to one side of the open- 'mg 17 with a die recess 19.
A movable die 20 is mounted in a die holder 21 carried by the cross head 3 and 1s provided with a die recess 22 adapted to co-operate with the recess 19 in theblock 16 to form balls from the stock.
A receiving and holding block 24 is mounted to reciprocate across the breast plate 15, and has its inner end face provided block 24 is adapted to be moved inward to a point where its inner end face will be in line with the center line of the die recess 19 to receive the pieces of stock from which ballsare to be formed and to retain such position until after the stock is engaged by the movable die, and to then be quickly withdrawn out of the path of said die.
The block 2a is adapted to be reciprocated by a rock shaft 26 journaled in bearings 27 on the frame 2 of the machine and having 'anupwardlyextending lever 28 secured to its forward end and pivotally connected toa pin 29 secured in the block 24:. A second lever 30 is secured to the opposite end of the with a semi-circular recess or notch 25. The 90 notch or recess 36 in its inner or shearing end adapted to fit around the stock. The blade 35 is adapted to be moved across the breast plate 15 and engage and cut off the portion of stock projecting through the opening 17 and move said cut piece of stock sidewise across the breast plate and stationary shear and. die block and into the notch 25 in the receiving block 24, at which point the stock will be in line with the dies. The
shear blade 35 will remain in this position until after the movable die 20 engages the stock, at which time the blade will be quickly withdrawn out of the path of the movable die.
The shear blade 35 is adapted to be moved during its shearing or working stroke by the side ram 4 and to be withdrawn in the reverse direction from the path ofthe movable die 20 by a rock shaft 38. The shaft 38 is journaled in suitable bearings 39 on the frame 2 of the machine and is provided with an upwardly extending lever 40 on its forward end, which is pivotally connected to a pin 41 secured in the blade 35, and a second lever 42 is secured to the opposite end of the shaft and eitends upwardly into the path of a cam member 43 carried by the cross head 3. The'lever 42 is provided with a roller 44 at its upper end adapted to ride on the cam member 43 A coiled spring 45 is mounted on the shaft 38 under tension so as to normally move the blade 35 inward to its stock receiving or shearing position.
The stroke of the side rain 4 is at the same speed in bothdirections, and, therefore, means must be provided for permitting a quick withdrawal of the shear blade 35 from the path of the movable die. In order to provide a space into which the blade 35 may be moved by the shaft 38 and its actuating cam, a filler block 47- is 'slidably mounted to be moved between the blade 35 and side ram 4 during the shearing stroke and to be Withdrawn just prior to the return movement of the shear blade 35 to provide a space into which said blade may be moved.
The block 47 is mounted on the ram 4 for a sliding movement transversely thereof. The block 47 is adapted to be moved by a lever 48 having one end pivotally connected as at 49 to a pin 50 secured in the block and having its other end secured toa shaft.
Y is adapted to operate the lever 53 so as to rock the shaft 51 and withdraw the block 47 from between the side ram 4 and blade and coiled springs 56 and 56 are mounted on the shaft 51 under tension so as to normally rock the shaft 51 in the reverse direction. Therefore, when the shaft is rocked by the cam member 55 to withdraw the block 47, the tension of springs 56 and 56' will be increased, and when the cam member is withdrawn from engagement with the lever 53 the springs 56 and 56 will immediately reversely rock the shaft 51 and re turn the block 47 to its position between the blade and ram 4.-
The die block 16 is provided with a suitable aperture 16' opening into the die recess 19 through which an ejector bar 58 is adapted to reciprocate. The ejector bar 58 is pivotally connected to one end of a rocking beani 59 mounted on a pivot 60 and adapted to be rocked by a reciprocating rod 61 pivoted to the other end of the beam 59. The rod 61 has its forward end pivoted to the beam 59 and its rear end pivoted "to the lower end of a rocking beam 62, which is piv otally mounted as at 63 to the frame of the machine and has its upper end provided with a roller 64 adapted'to be engaged by a cam 65 on the crank shaft a v The movable die 20 is also provided with an aperture 20' opening into its die recess 22, through which an ejector bar 66 is adapted to reciprocate. The aperture 20" is enlarged at its rear end and alines with an aperture in the die holder 21 to form a spring retaining recess 67. The ejectorbar has its rear end projected through the recess 67 into a vertically disposed recess 68 in the die holder 21 and is operatively connected intermediate the ends of a vertically disposed operating lever 69, which has its lower end pivotally secured to the die holder 21 and its vupper end extended upward into the path of a stationary trip bracket 70.
A coiled spring 71 is mounted around the ejector bar 66 within the recess 67 and is standard Ajax heading machine is shown tail.
in Figure 6 of the drawings. This gage is mounted on a suitable shaft 76 and operatively connected to the other moving parts of the machine so as to swing into position of the path of the other moving parts-of the machine. This gage does not form a part of my invention and since it would only tend to confuse the other features of the machine, it has not been shown in the other figures of the drawings or described in de- It will. of course, be understood that the. machine is clearly operative without the gage shown, and that any other suitable gage may be used if desired.
A complete cycle of operation of the machine will a now be described. Assuming that the machine is in operation, a hot round stock bar will be fed by the feeding mechanism 18 through the stock inlet opening 17 until it is stopped by the gage 7 The feeding mechanism will then auto-,
matically stop and the gage 75 will swingup out of the stock engaging position. The stock receiving block 24 will be in position to receive'the piece of stock to be forged into a ball, and the filler block 47 will be positioned between the shear blade 1-35 and side ram 4. After the gage 75 is raised out of stock engaging position the side ram 4 will move inward, thus forcing the shear blade against the stock to shear off a piece and carry the sheared piece sidewise into the notch 25 in the stock receiving block 24. The blade 35 and block 24: cooperating to hold the sheared piece of stock in linewith the recesses 19 and 22' in the die block 16 and movable die 20, respectively.
The cross head 3 will have started forward during the above operations and will move the die 20 into engagement with the piece of stock held by the block 24 and blade The cam arm carriedby the cross head 3 will engage the roller 54 on lever 53 and rock the shaft '51 and lever 48 to positively withdraw the filler block 47 from between the side ram 4 and shear blade 35. Just as the filler block 47 is withdrawn, the cam arms 31 and 43 will engage and operate the levers on rock shafts 26 and-38, respectively, to positively withdraw the stock ,receiving block 24 and shear blade 35 from the path of the movable die 20 and thus permit the die 2 to force the stock piece into the die block 16 and form a ball. The withdrawal of the filler block 417 gives space into which the shear blade is moved by the cam operated rock shaft 38. As the shafts 26, 38 and 51 are rocked by the earns 31, 4:3
and 55, respectively, their respective coiled springs 33, and 56, 56" are tensioned so that when the cross head 3 reverses or moves rearwardly and the cams release their re-. spective shafts, such shafts will be auto matically rocked in the reverse direction block into position between said and said ram, a receiving block movable 1 so as to move the stock receiving block 2% into stock receiving pos1t1on,'the blade into position to shear another piece of stock,
. and the tiller block -17 back into position to gage the stock and then swing back outbetween the rain at and blade 35 in readiness toagain gothrough the above cycle of operations.
As the cross head 3 approaches its rearmost position on the returnstroke the cam 5 will engage the rocking lever 62 and the lever (35) will engage the trip'TO to operate the ejector rods 58 and (36, respectively, forcing the rods into the die recesses 11) and respectively, to eject the preformed ball if it should stick in either ol'lhe dies.
While I have shown and described one specific embodiment of my invention, it will be understood that I do not wish to be limited thereto, since various mod ilications may be made without departing from the scope of my invention as delincd in the appended claims.
