' Application nea May 27,1893. senin.. 475.789. cromati.)
To @ZZ whom t may concern:
Beit known' that'I, CAMPBELL P. HIGGINS, a citizen of the United States, residing at Roselle, county of Union, and State of New Jersey, have invented certainy new and use ful Improvements in Punching and Forming Machines, of which the following is a speciication. c
This invention embodies various n ovelelements which are applicable to machines for the manufacture of wrought metal drum# heads, and in order to enable others skilled in the art to which this said invention appertains, to understand and use the same, I will proceed to describe the various details of its construction, explain its operation, and\point teristics.
Referring to the accompanying drawings,` Figure 1, is a side elevation in Vpreparatory position; Fig. 2, a front sectional elevation taken on the line --w, Figs. 1, and 4, in preparatory position; Fig; 3, a partial sectional side elevation taken on the line fyy, Figs. 2, 4, and 11, in Hanging position; Fig. 4, a horiand 2; Fig. 5, ahorizontal section taken onv the line .'r-, Figs. 2, and 3.` Figs. 6, 7, andV 8, are sectional detail views showing the difp ferent positions respectively of punching, inserting the stiffening collar, and forming, taken in planes of section corresponding to the plane of section in Fig. 2. Fig. 9, is an enlarged sectional detail view of the dies, corresponding in position to Fig. 8, of forming, taken in a plane of section indicated by the line y-y ,in Figs. 4, and 11; Fig. 10, is an corresponding in position to Fig. 3, of flanging, and taken ina plane of section indicated Fig. 11, is an enlarged horizontal section taken on the line z-.e, Fig. 10, showing an inverted View ofthe parts. Fig. 12, is a detail view showing one of the segments of the castingo collar inverted. Fig. 13, lis an enlarged sectional detail view of the dies, taken on the line :r2-x2, Figs. 4, and 11,showing the manner in which the work is cast oif when completed.
1, is the base of the press; 2, the head of the press; 3, the pillars or tie rods ;4, the upper or fixed platen; 5, the lower or movable platen; 6, the upper forming die which when active, occupies anl advanced position upon the upper platen 4, as in Figs. 1, 2,/6, 7, 8, and 9, but when inactive is permitted to retire to ward the platen`4, as in' Figs. 3, and 10; 7, the' lower forming die permanently secured to the movable platen 5.
8, is the iianging collar permanently lixed to the upper platen 4.
10, is thev malepunching die which may be connected or disconnected with the upper platen 4.
11, is the female punching die which is connected to an independent head 12, provided with means for its advancement, as in Figs.
2, and 6, or retraction in the platen 5, as i Figs. 3, 7, 8, 9, 10, and 13. v
The enlargement 13, of the male punching die 10, servesto form, and inwardly flange the man-hole in plate 14, as in Figs. 3, 8, 9,-and 10, after it has itself been formed over the stiffening collar 15, previously formed by another machine, and inserted as in Fig. 7, in
vthe recess '16, (Fig. 6,) provided therefor in the lower forming die 7.
20, are movable interposing blocks which are advanced by hydraulic plungers 21, in cylinders 22, controlled by introduction of pressure applied through pipes 60. The interposing blocks 20, are retracted by constant water pressure from pipe 61, within said plungers 21, between the same and the stationary pistons 23; the application of pressure for effecting'the advancement of the said interposing blocks being effected at will through the agency of 'suitable valves. p ing blocks 20, are always interposed between the lianging collar 8,' and the upper fixed platen 4, and said interposing blocks when advanced toward one another occupy an interposed position between the upper forming die 6, and said platen 4, as in Figs. 1, 2, 6, 7, 8, and 9, but when retracted permit the upper forming die 6, to retire within the iianging collar 8, so as to rest directly against the upper platen 4, as in Figs.` 3, 5, and V10. rIphe edges of the interposing blocks 20, which arev The interpos- IOO 25, in the shank 26, of the punching and man-y hole forming die 10, and 13. The punching and manhole forming die 10, 13, is raised up against thc forming die 6, as in Figs. 1, 2, G and 7, and the said blocks 20, then brought t0- gether, securing the said die 10, 13, in its suspended position preparatory to the first step of operation.
30, Figs. 2, and 3, is the hydraulic cylinder for operating the forming and Hanging mechanism, provided with a plunger 3l, carrying the lower platen 5, on its base plate or platen proper 32. The plunger 31, serves also as a hydraulic cylinder within which the lifting rain 33, is operated, carrying the head 12, which supports the female punching die 11, to be operated independently of the forming die 7. The female punching die 11, is provided beneath it with a transverse mortise 34, for the removal of the pieces punched ont.
40, is a segmental casting-ottl collar, which is made in four segments, as indicated in Figs. 4, and 11, and tapered interiorly so that when raised, as in Fig. 13, said segmental collar may contract to release thc work. The segments of said collar are slightly separated at their joints when depressed into forming position, so as to permit said contraction when raised.
41, represents hydraulic plungers operated within cylinders 42, to raise and lower the segments of the collar 40, the movements of said plungers being effected by any suitable hand valves.
The hydraulic pressures in cylinders 30, and
31, and the motions of their respective plungers determined thereby, aie controlled by any usual or suitable character of valves applied to pipes 50, and 51, which, being well known to the art, will not require specific description herein.
The operation of the machine is as follows: The male punching die 10, is raised by the lifting ram into the position shown in Figs. 1, and 2, and the interposed blocks 20, advanced between the forming die 6, and platen 4, until their tongues 24, enter the gains 25, in the shank 26, of said punching die 10, holding the saine securely in position for punching. The platen 5, being in its retracted position the blank plate 14, is linserted as in Fig. 2. Water is introduced into the cylinder 31, elevating the female punching die 11,so as to punch the plate as in Fig. 6. After punching the manhole opening through the sheet, these two rams can then act independently. The female die 11, is then retracted as in Fig. 7, leaving the plate 14, to adhere to the punch 10. The sttfening collar 15, is now inserted in the recess of the forming die 7, as in Fig. 7, and pressure applied to the cylinder 30, advancing the platen 5, and forining die 7, within which the die 11, is now retired into au inactive position. The advance motion of the forming die 7, against the forming die 6, first forces the plate 14, over the enlargement or shoulder 13, of the punch 10, so that the margins of the manhole in the plate 14, are formed upon the stilTenng colinterposing blocks 20, are then retracted tothe position shown in Figs. 3, and 5, and the manhole punching and forming die 13, permitted to drop through the manhole into an inactive position, as in Figs. 3,8, 9 and 10. Pressure is again applied to cylinder 30, advancing the platen 5, so that the forming die 7, abutting against the forming die G, new released, will push the same into the ilanging collar S, while the latter remains in its fired position, and forms the flange on the perimeter of the plate 14, as in Figs. 3, and 1Q; the flanging collar 8, being guided concentiically with the work by means of guides 70. Pressure being again released from cylinder 30, the platen 5, is permitted to retract, leaving the work on the forming die 7, which work 1S afterward ejected by the segmental collar 40, in the manner aforesaid, and as illustrated in Fig. 13.
Having described my invention, what I claim is- 0 1. In a punching and forming machine, the combination of a stationary platen, the forming die supported thereon, the punching and forming die movable relatively to said forining die, thc movable blocks for securing the punching die in a fixed position relatively t0 the said forming die, Vthe movable female die and the inovable forming die, substantially as specifltd.
