PUNCH-PRESS.
Specification of Letters Patent.
Application led May 21, 1910.
Patented Apr. 11, 1911. serial No. 562,640.
To all whom it may concern.:
Be it known that I, PETER E. BAGGE, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Punch-Presses, of which the following is a specification, reference being had therein to the accom panying drawing.
The present invention relates more particularly to presses for punching, but is by no means limited to presses of this type, as various features may be employed on or in connection with apparatus of the same genera-l class, but for different purposes.
@ne object is to provide comparatively simple mechanism of a novel character, which may be adjusted so as to vary the amount of movement of the plunger or ram member, without in any manner changing theV initial driving` member.
A further object is to provide simple and effective means for operating an auxiliary plunger' with respect to the main plunger so that compounding dies may be employed.
A still further object is to provide novel and simple means for actuating the ejecting mechanism, and another and important object is to provide means, whereby the ram or plunger can be readily thrown into or out of operation, without stopping the main or initial driving member of the machine.
Gther objects will appear from the following specification. l
An embodiment of the invention that is at presentconsidered the preferable one, is illustrated in the accompanying drawings, wherein Figure 1 is a side cross sectional elevation of the machine. Fig. 2 is a plan view. Fig. 3 is a detailv view of a part of the ejector operating mechanism, in tripping position. Fig. 4 is an enlarged detail view along the line 4-4 of Fig. 1, and showing the clutch mechanism. Fig. 5 is an enlarged detail view taken along the line 5 5, of Fig. 4 looking upward.
Referring to the drawings, 1, represents the main frame of the machine to which the other parts are attached. The frame is provided with a horizontally extending bed, a forward upright 3, and spaced upstanding side walls 4, which connect the base 2, and
the upright 3. The side walls 4 are preferably provided with laterally extending reinforcing flanges 5.
6, 6, represent cap plates bolted to the forward side of the upright 3. The two parts 3 and 6 are provided with oppositely disposed parallel grooves 7 and 8 which are adapted to serve as guides and bearings for a vertically reciprocal plunger 9. The plunger 9 is provided with lateral tongues or extensions 10, 10, which are of the same length as the plunger itself. Each of the tongues 10 is cut away near its center, the upper and lower edges of the opening 11 thus formed, being cylindrical surfaces having a common center.
12, 12, are two plunger operating levers each of which is provided at its forward end with a partly cylindrical enlargement or pivot 13, which is adapted to iit into and turn in the opening 11 in one of the plunger tongues 10, the upper and lower curved sides of which serve as bearings for the pivot.
j 14, is a yoke or cross bar which extends transversely between the two side walls 4, and which is pivotally mounted at its ends in bearing blocks 15. The blocks 15 are slidably mounted in suitable horizontal guide ways 16 which are formed on the side walls 4. Preferably the guide ways 16 are provided with guide tongues 17 which engage with similarly formed grooves in the upper and lower surfaces of the bearing blocks. The yoke 14 is provided with two depending eyes or lugs 18 through each of which extends one of the operating levers 12. The levers are adapted to slide relatively to the yoke through the eyes 18. A screw 19 is mounted above and between the levers 12. At its forward end it extends through a threaded aperture in the yoke 14 and at its rear end it is mounted in a bearing` bracket 20 which extends transversely of the levers. Collars 21 and 22 connected with the shaft, engage the bearing bracket and prevent relative longitudinal movement of the shaft. One of the collars, as for instance 22, is provided with sockets for the engagement of a hand lever 23 by means of which the same may be turned. It will be evident from the drawings that the pivoted ends of the yoke 14 serve as a center of oscillation for the levers 12. By turning the screw 19, the yoke 14 may be moved relatively to the levers and in this way their center of oscillation may be changed.
At the rea-r end of the machine there is provided a main operating shaft 24, which may be provided with a belt wheel or fly wheel 25. The shaft 24 may be provided with a crank or an eccentric, as preferred.
For purposes of illustration I have shown the shaft provided with a crank 26 to which is connected the lower end of a connecting rod 27. The upper end of the connecting rod 27 is provided with a rectangular longitudinally extending slot 28.
29 is a rectangular block slidableY in the slot 2S and provided at its ends with pivots 30, which are mounted in suitable bearing apertures formed in the levers 12. The slot 28 is provided with two smaller oppositely disposed transverse slots 31 and 32.
33 is a turn button or latch pivotally mounted on the underside of the block 29. The latch 33 is so formed that when in one position it will be freely movable in the slot 28. Then the block 29 is .in its uppermost position in the block 23, the button or latch 33 may be turned through 90 degrees and its ends moved into the slots 31 and 32, thereby locking the slot 29 and the levers 12 to the connecting rod. Any desired means .may be used for operating the latch 33. That which l: prefer however, comprises two connected links 34 and 35, one of which is connected to a bracket 34a on the block 29, and the other of which is connected to the latch 33. In Figs. 4 and 5, the full lines show the latch in position to permit movement of the connecting rod relative to the levers. By means of a wire cable 36, or other suitable device, connected to one ofthe levers, as for instance 34, the parts may be moved to the dotted positions shown in Fig. 5. A stop 37 is provided at one side of the slot 32 to limit the movement. of the latch. A coil spring 38 is connected at one end to the latch and at the other end to a bracket 39, on the opposite side of the block 29 from the bracket 34a. This spring tends at all times to move the latch into its inoperative position, the movement of the latch being again limited by the stop 37.
The wire cord 36 is preferably extended over a suitable guide pulley such as 40 to a foot lever 43 which is mounted upon a rock shaft 42. The pulley 40 is preferably mounted on the yoke 14. A depression of the foot lever serves by means of the connecting cord 36 to flex the toggle joint formed by the links 34 and 35 and to thereby throw the latch 33 into operative position.
ln order to prevent the spring 33 from immediately returning the latch to its inoperative position, a suit-able catch for the foot lever may be provided although if preferred the foot lever may be held down by the operators foot. The catch which I have shown in the drawings for purposes of illustration, comprises a pin 44 on the foot lever and a. spring latch 45, formed with a rounded projection 4G adapted to engage the pin to hold the lever depressed.
Then it is desired to throw the machine out of operation, a simple pressure on the upper end of the latch 45 will move it into position to permit the latch 33 being moved by the spring 3S. When the latch 33 is in inoperative position the connecting rod 27 may move up and down without moving the levers 12.V A stop 12a is provided for supporting the rear ends of the levers when they are not connected with the connecting rod.
47 represents a secondary or auxiliary plunger which is slidably mounted in a suitable socket formed in the lowerV end of the main plunger 9. The plunger 9 is provided with two opposite vertical slots 48 through which extend pins or trunnions 49 secured to the secondary plunger 47. At each side of the plunger 9 is a pair of links 50 and 51 connected together at 52. The upper end of each of the links 50 is pivotally connected to the plunger 9 as indicated at The lower end of each of the links 51 is pivotally connected with one of the pins or trunnions 49 which are secured to the auxiliary plunger 47.
54, 54, are two links, each pivotally connected at its forward end to one of the connections 52 between the links 5() and 51 and each connected at its rear end to one of the upright cam levers The cam levers are pivotally connected at their lower ends to the bed 2 of the machine, and their curved upper ends extend between pairs of rollers 56 and 57 mounted on the levers 12. The upper ends of the levers are so shaped that they will be moved forward by the rollers 57 as the rear ends of the levers 12 are depressed. This movement of the levers 55 is transmitted through the links 54 and the toggle links 50 and 51 to the auxiliary plunger 477 the result being that the plunger 47 is raised relatively to the plunger 9. When the levers are raised the rollers 56 move the levers 55 back to their first positions andthe plunger 47 is lowered relatively to the plunger 9.' It will be noted that this movement of the auxiliary plunger relative to the main plunger adapts my punch for use with compounding dies. lt will furthermore be noted that by properly shaping the upper ends of the levers any desired motion of the auxiliary plunger relative to the main plunger may be ob tained.
58 is an ejecting bar slidably mounted in suitable bearings on the main frame of the machine. A spring 59 tends to normally hold the bar in retracted position.
llO
G() is an ejector operating lever pivotally mounted on the bed 2 of the machine at its lower end and connected near its upper end with the bar 58 by means of the link 6l; A shaft 62 extends transversely between the levers l2 and is mounted in suitable bearings G3. At the center of the shaft 62 is a depending dog 64twhich is adapted to enter and engage with a pocket 65 formed in the upper end of the lever G0.
6G is an adjustable block secured to the lever 60 and forming the forward edge of the pocket G5. As the levers 12 descend, the dog G4 engages the upper end of the lever 6() and forces it forward. After a certain amount of movement the arm 67 at the rear side of the pocket 65 engages the dog 64: as shown in Fig. 3, and forces it out of engagement with the block 66, the spring 59 then immediately returns the parts to normal position.
It will be noted that the extent of the movement of the ejector is entirely independent of the amount of movement of the levers l2 and it will. furthermore be noted that the movement of the ejector may be adjusted by changing the position of the block 66 relative to the lever 60.
The operation of my press will be evident from the foregoing specication without further exact description. Attention is directed however to the means of changing the stroke of the plunger 9 by adjusting the pivotal mounting of the levers l2; to the improved clutch mechanism for connecting the main operating levers with the connecting rod; to the improved means for obtaining movement of the secondary plunger relative to the main plunger; and to the improved ejector operating mechanism.
