Application November 17, 1936, Serial No. 111,214 16 Claims. (Cl. 29-34) My invention relates to’punch presses and has replace the various cams Without disturbing any particular reference to presses adapted to form other parts of the press, having at the saine time various articles from sheet metal. a number of slidesreciprocating in direction of The object of my invention is to provide a punch press which can be used to produce sev eral individual parts and to assemble them into a more or less complete article during one cycle of operations of the press. For this purpose I provide means to support several dies producing corresponding number of pieces during each stroke of the ram of the press, there being prefer ably several strokes of the ram during one revo lution of the main flywheel of the press. I also provide supplementary reciprocating members, also operated by the main flywheel, likethe ram, which can be provided with means to support various tools for performing additional oper ations on the pieces produced by the dies, also for assembling these pieces together, including certain parts delivered to the press from the out side sources. Another object of my invention is to provide means for stopping andA starting the driving. mechanism within several cycles `ora. fraction’ ofi a cycle, the stopping means being manually con trolled, including a remote electrical control. For this purpose I provide a clutch, preferably of a jaw type, between the driving flywheel and the driving shaft in` the press, and a cam-shaped bushing on the driving shaft, which is under ac tion of springs tending to press it against the clutch thereby engaging the latter. The cam` is moved by a pin in the frame, which can be moved in and out of engagement with the cam. B-y releasing the pin, the driving shaft can be made to stop at a desired point in the operating cycle of the press, for instance. when the“ ram , and the reciprocating members are moved> away' from the dies. Another object of my invention is to provide means to- individually feed stock to the different dies and tools, also to feed separately prepared parts to- be assembled withv the articles made in the dies. I also provide means tor adjust the rate of feed simultaneously for dilferent dies and sepa rately for each die. For this purpose I provide> adjustable operating levers and replaceable or changeable gears- for the feed mechanism. the operating zone, and which can be arranged to perform Various additional operations on the 5 ' articles being produced by means of various tools mounted on the inner portions of these' slides. Another object of my invention is to provide a number of cam members on the end of each shaft, each cam member operating a separate slide, the 10 slides operated by one shaft being arranged in sliding relation to each other. The cams are pref erably made of different diameters, the inner cams being smaller, so that the corresponding slides can be placed under the slides from the 15 outer cams. Still another object of my invention is to pro vide additional fixtures or tools for the slides in the form of turret heads and ratchet wheels, so that each slide can be made to perform several 20 different successive operations during its several strokes during one cycle. With my punch press it is possible therefore to perform o-n a single machine various operations which would otherwise require the use of several separate presses, drop hammers, assembling ma chines, and additional manual operations.. It is also possible to perform these various operations in a single automatic cycle, thereby obtaining a finished and assembled product directly from the 30 machine without any intermediate manual or other operations. My invention is more fully described in the ac companying specification and drawings, in Which35 Fig. 1 is an elevational view of my punch press employing a toggle drive. Fig. 2 is a similar view of a punch press ern ploying an eccentric drive, showing also a feed ing mechanism. 40 Fig. 3 is a detail View of a slide drive by cams.

Fig. 12 is a detail view showing a preliminary stage in the assembling of the caster head. Fig. 13 is a detail view showing another pre liminary stage in the assembling of the caster head. Fig, 14 is a top plan view of the machine fully assembled. My punch press consists of a` frame | with a bolster 2 which may be formed integrally with the frame as shown. A ram 3 is slidably supported on gibs 4 and has a face plate 5 operating dies 6, 1 supported on the face of the bolster 2 in a usual manner. The gibs and the sides of the ram are made with a slight taper so as to provide a closer fit when the ram is operating the dies than when it is moved away from them. This insures more accurate ñt of the dies and conserves the cutting edges. The gibs are shown located hori Zonta-ily, although, of course, they can be made inclined with a correspondingly inclined bolster. In a particular embodiment shown in Fig. 1, the 25 ram is reciprocated against the bolster by a toggle mechanism consisting of levers 8 and 9 pivotally connected at I8 and ll with the ram and a toggle block l2. The latter is held by tie rods |3 and |4, the latter being cast in the frame |. The lever 8 is pivoted at I5 to one end of a toggle rod IG, the other end of which is journaled on an eccentric portion l1 of a shaft I8. The latter has a gear |9 in mesh with a gear 20 on a main driving shaft 2l. IThe gear 2li is shown of a larger diameter than the gear I9 so that the ram makes more than one stroke for each revolution of the main shaft. A gear 22 on a shaft 23 is con nected by a belt or chain 24 with a hopper or feeder' 25 for small parts which are delivered through a chute 25 to dies for assembling with the stampings. These parts are also shown in Fig. 4, the gear 22 being shown in dotted lines and provided with a pulley 21 for the belt. A fly wheel 28 freely rotates on the outer extension of the driving shaft 2| and can be connected by a belt with a suitable source of power (not shown) for its operation. The flywheel has one or more teeth 29 which can engage corresponding slots 3Q in a sliding jaw clutch 3|. The ciutch 3l is keyed to the shaft 2| so that it connects the flywheel with the shaft when the tooth 29 engages one of the slots 38. The clutch is pressed against the iiywheel by springs 32. It has an enlarged cylindrical portion 33 with a cani-shaped edge 54 engaged by a pin 35 slidably supported in a bearing 38 in the frame. The pin is pressed by a spring 31 against the clutch 3|. When the clutch is engaged, it rotates with the shaft 2|, and the pin 85 follows the curvature of 60 the cam-edge 34 until a projecting portion of the cam engages the pin thereby forcing the clutch back and releasing the tooth 29. The position of the pin between its collars 43 thereby retaining the pin in an inoperative position. To stop the press, the lever 45 is turned back thereby releas ing the pin, which snaps in its position at the cam and stops the press as soon as the hump of C21 the cam engages the pin. The lever 45 has an extension 41 connected with a plunger 43 of a magnet 49. This magnet is controlled by push buttons at convenient places and can be used for stopping the press from various remote points. It cannot be used to start the press, however, and serves principally as a safety device and to insure quick stopping if there is any fault inv the press operations. A modified form of drive for the ram is shown in Figs. 2 and 4. a ram 52. The frame 58 has gibs 5| for A stub shaft 53 is journaled in a clevis 54 at the end of the ram, the shaft having a hole for the threaded end of a driving rod 55 held by nuts 56. The other end of the rod 55 has a bearing for an eccentric portion of a shaft 51 connected by a gear 58 with the driving gear 28. The bolster 2 which supports dies 6 and 1 shown in Fig. 1, also supports feed slides 59 on rails 68, there being individual slides for each die. Two slides are shown but there may be a larger number of them arranged side by side, all op erated by individual levers 6|, 62, connected with the slides by links 53. The levers 5| and 82 are connected gears 64, 85 rotatively mounted ;, between collars 66’ on a shaft 68 fitted by its ends in the sides of a. frame extension 81. The gears 64 and 65 are in mesh with gears 83 and S9 keyed on a shaft 1|) journaled in the sides of the ex tension 61 and having a lever 1| on one end. l The lever 1| has a slot 12 for a bolt 13 connect ing it to one end of a link 14 the other end of which is connected by a bolt 15 passing through a slot 16 with a lever 11. This lever is pivoted at 18 in a bracket 85 and has a sliding block 19 40 with a pin 30 engaging a cam slot 8| in a cam cylinder 82 mounted on the end of a shaft 51. By changing the position of the bolts 'f3 and 15 in the levers 1| and 11 it is possible to change the rate of feed for stock 84, usually in the form of strips of metal. The feed can be also changed individually for each slide 69 by changing the respective gears 64 and 58 or 65 and 89. The cam slot 8| may be made for different length of feed stroke, and it can be made to produce one 50 or more feed strokes during one revolution of the shaft 33. The shaft 51 has a second cani cylinder 86 with a cam slot 81 engaging a pin 88 on the end of a slide 89. The other end of the slide has a notch 9|) or similar arrangement for holding different tools used for supplementary operations on parts stamped out by the dies from the stock 34. The end of the shaft 51 has a bevel gear 9| in mesh with gears 92 and 93 preferably at right angles stop the machin-e. The pin has also collars 43 to the gear 9|. The gears 9|, 92, and 93 are lo cated in the middle portion of the press near the dies and substantially at the sides of an opening 94 for scrap falling from the dies. The gears 92 and 93 are mounted on the ends of shafts 95, 95 extending outside of the frame and having on their outer exposed ends cam cylinders 98 and 91. The cylinders have cam grooves 98 and 99 for rollers |00 and 59| on the ends of slides |íl2 and |03. The slides |82 are placed under the which can be engaged by a slot 44 in a hand lever slides |03, which is made possible by having the 45 pivotally supported at 46 on the frame. In order to release the clutch for continuous opera tion of the press, the pedal 4l is depressed and the lever 45 turned by hand until its slot engages cam grooves 98 of a smaller diameter than the grooves 99, as may be seen more clearly in Fig. 3. The outer end of the inner slide |02 has an the hump on the cam is arranged so that the press stops when the ram is moved away from the bolster to facilitate work with the dies. The pin 35 has an extension 38 pivoted at 39 to a bar 40 having a pedal 4! at one end and being pivoted at the other end on a pivot 42. By stepping on the bar, the pin 35 is withdrawn and cannot then additional roller |84 resting against the inner 2,116,326 3 flange of the outer cam cylinder 91, thereby pro eral independent feeds for separate dies, it is pos viding a better bearing surface for exerting a. sible to make several `separate stampings by a pressure on the work by tools on the inner ends` single stroke of the ram; the working stroke of` of the slides. The rollers |00 are smaller and the ram occupying a fraction of one revolution Ul lighter and are used only or mostly for retrieving of the driving shaft, the remaining portion of the the slide, when it does not perform any heavy revolution can be used for performing additional y. Ul duty. Similar cam cylinders |05 and |00 are operations on the stampings. delivered from the mounted on the end of a short shaft |01 .con- ‘i main die, using for these additional operations nected With the driving shaftv 2| by spur gears multiple slides working from four different di|08 and |09. With this arrangement there are four sets of slides converging by their inner ends to a zone `of operations near the main dies 3 and 1 where they can be used to perform various sup plementary operations on stampings or similar rections, there being more than one slide in each direction; these additional operations can be further expanded or elaborated by using ratchet operated dials and turret heads on the slides; parts produced by the dies. The four sets of slides, converging from four using these various devices to assemble together diiferent directions to the Zone of operations, are driven by three central bevel gears and two outer spur gears. This arrangement `permits to have delivered by separate feeding devices. a free space for the scrap hole 94 where otherwise may have been the fourth bevel gear for >the slides. ‘ By combining operations by the tools `on the slides with the operations performed by the main dies, it is possible to produce more or less com plicated articles entirely automatically. One ex~ ample of such articles is shown in Figs. 5 and 6 representing a belt buckle ||0 with a claspy | | l. Another example is shown in Fig. 7 representing a stamped head of a caster with a disc | l 2 wedged between the ends of the head | I3 and provided with a central bearing H4. The method of mak ing this article is shown in Figs..8 to 13 incl. For this work a turret head I | 4’ is employed rotative 1y mounted on a pin | | 5 fitted in the end portion of the slide |02. The head ||4 works against a die IIB by its tools ||1, IIB, and H9. A ratchet wheel |20 is mounted on thehead H4 and is turned by a pawl |2| pivoted at |22on alstation« Il O ary portion of the frame of the press.` A punch |23 is also mounted on the slide` i 02 and works in cooperation with adie block |24. A suitable parts made on the different dies of this press, in cluding also parts made o-n other machines andv Another important advantage of my press is that it can be easily changed from a toggle ram to an eccentric ram, the rest of the machine «in cluding its drive rem-aining unchanged. This is important when it is desired occasionally> to change the type of work on the press: for light work, where a low power expenditure is preferred, the eccentric drive will be used; and for a heavy 25 work it may be changed over to the toggle drive. Another important advantage resides in the construction of my clutch. The cam 34 can be provided with as many projections to be oper ated by the pin 35, as there are strokes of the 30 ram in one revolution of the driving shaft, and the projections can be located so that the clutch Y becomes disengaged before the stroke of the ram, thereby stopping the machine in time to prevent theoperation of the ram when the operation is I no longer wanted or is dangerous to the Work. This feature of the clutch is especially useful in connection with the electromagneticV control of the pin 35. The magnet can be controlled by push buttons placed conveniently in various places 40 around the machine where the operator may need them for stopping the ram in time to prevent its punch (not shown) pierces holes in the strip B4’ operation, or where some adjustments may be into which bearing bushings ||4 are fed by a needed. The magnet can be also controlled auto chute 26 from the hopper 25.
