SPECIFICATION forming part of Letters rafent'No. 610,585, dated'september 13,1898.
' Application led December 4, 1897. Serial No. 660,755. (No model.)
To all whom it may concern:
Be it known that I, GEORGE GUILD, of Cambridge Oity, rayne county, Indiana, have invented certain new and useful Improvements in Bending-Machines, of which the following is a specification.
This invention pertains to improvements in machines for bending sheet metal in forming boxes, pans, moldings, rbc., and the improve- 1o ments will be readily understood from the following` description, taken in connection with the accompanying drawings, in which- Figure lis a front elevation of a machine embodying my improvements; Fig.'2,a plan of the same; Fig. 3, a side elevation, and Fig. 4 a vertical transverse section of the dies and their holders.
In the drawings, 1 indicates a sole-plate; 2,
ahead-plate; 3, four columns uniting the solezo plate and head-plate and with them forming the frame or body of the machine; 4, a die-carrier having ears engaging the columns 3, so as to slide thereon to and from the head-plate; 5, a pair ofhydraulic cylinders vertically disposed z 5 on the sole-plate, one between each pair of columns and under the ends of thedie-carrier 4;
6, a pipe for supplying these cylinders with liquid under pressure; 7, the rams of the cylinders, extending upwardly from the cylinders 3o into rigid attachment with the under surface of the die-carrier 8, a pair of studs having enlarged bases secured removably at the ends of the die-carrier and projecting upwardly therefrom between the columns; 9, vertical screws 3 5 threaded into nuts on the head-plate, these screws being disposed vertically over the studs 8; 10, a worm-wheel splined on each of the screws 9; 11, a handled worm-shaft mounted in bearings on the head-plate and serving 4o to give simultaneous rotary motion to the two worm-wheels 10, whereby the turning of the shaft serves in vertically adjusting the lower ends of screws 9; 12, the lower die-holder or die-holders in the form of a sectional plate resting edgewise on the die-carrier 4, to which it is firmly secured by bolts through a flange in its base, the upper edge of the die-holder 12 being provided with an upwardly open groove; 13, the lower dies in the form of plates 5o with their lower edges seated in the groove in the top of die-holder 12, the upper edge of thesedies having a cross-sectional form suited to the form'of bend to be produced, the exemplification showing these dies as having angular edges suited for square or bevel bends; 14, an Yupper die secured to the lower surface of the head-plate and having along its lower surface a die-groove forming a counter-die corresponding with the upper edge of dies 13; 15, sectional upper dies in the form of blocks 6o removably secured to and projecting downward vfrom die 14, these sectional upper dies having in their lower su rfaces counter-grooves vto cooperate with lower dies 13;16, guidebrackets on the lower surface of the headplate to the rear of die 14; 17, carriages sliding on these guide-brackets; 18, a gage-plate secured to these carriages and presenting its forward face parallel with the dies and eX- tending somewhat below the upper dies; 19, 7o screws journaled in guide-brackets 16 and threaded into the carriages 17; 20, Wormkwheels on these screws, and 2l a handled worm-shaft for operating screws 19 simultaneously, whereby gage 18 may be adjusted to 75 and'from the upper dies.
By properly admitting liquid to the two cylinders 5 it is obvious that die-carrier4and the dies carried by it will be pressed upwardly to the upper dies, this upward lno- 8o tion being limited by studs 8 coming in contact with screws 9, which screws may be adjusted by means of shaft 11, so that the lower dies will enter more or less into the upper dies. 85
In cases where a sheet is to have Vonly one bend or several parallel bends a lower die may be employed having any length within the capacity of the machine, and such die may coperate directly with long .upper die 9o 14; but where a sheet is to be bent and then have additional bends at right angles to the first bend-as, for instance, in turning up the sides of a square pan or boX-thenthe long lower die may not answer, and in such case the lower dies 13 are4 to have a length corresponding with the inside dimensions of such box or pan. Dies 13 of different lengths may be provided, and it is to be noticed that die-holder 12 is deeply notched to permit of roo the presence of those edges of the sheet metal formed by the first bendings and standing at right angles to the line of the bending to be done. The notches in die-holder 12 may obviously be notches in the integrally-formed die-holder or they may be formed by the separations between the sections of the dieholder if made in separate sections, and Fig. 1 may be taken as illustrating die-holder 12 as being formedin one or more pieces.
In some cases there may be reverse bends wanted, in which case the long upper die will not be satisfactory, and it also, like the lower die, will require to be notched or have special lengths. In the illustration the sectional upper dies 15 provide an upper die of definite short lengths with intervening notches.
The machine may thus be employed with a single pair of dies or a single pair of short dies or with a multiplicity vof pairs of short dies of varying length, and the dies are readily changed.
In using the machine the back gage 18 is properly adjusted, and then the sheet is held.
up against the upper die, its rear edge ooming against the gage, after which the lower die is moved upwardly to do the bending.
I claim as my invention- 1. In a bending-machine, the combination, substantially as set forth, of a sole-plate, a head-plate, rigid connections between these parts, a cylinder secured at each end of the sole-plate and projecting toward the headplate, a ram projecting upwardly from each cylinder, a die-carrier having its opposite ends secured to the respective rams, a pipe connecting both cylinders with a source of pressure-supply, and suitable dies carried by the head-plate and die-carrier.
2. In a bending-machine, the combination, substantially as set forth, of a sole-plate, a head-plate, two pairs of columns rigidly connecting the sole-plate to the head-plate, a cylinder secured at each end of the sole-plate between the two columns of the pair and projecting toward the head-plate, a pipe connecting both cylinders with a source of pressure-supply a ram projecting upwardly from each cylinder, a die-carrier having its ends secured to said rams and having sliding engagement with said columns, and dies removably secured to the undersurface of the headplate and to the upper surface of the diecarrier.
3. In a bending-machine, the combination, substantially as set forth, of a head-plate, a
die mounted thereon, a die-carrier arranged to move to and from the head-plate, a die carried by the die-carrier, means for forcibly moving t-he die-carrier toward the head-plate, studs projecting from the die-carrier toward the head-plate, stop-screws mounted in the head-plate in position to have their ends engaged by the ends of said studs, and arrest the advance of the studs and means for turning said stop-screws simultaneously.
4. In a bending-machine, the combination, substantially as set forth, of .a head-plate, a sole-plate, rigid connections between the soleplate and the head-plate, al die-carrier arranged to move toward and from the headplate, means for forcibly moving said diecarrier, a die supported by the .head-plate, a die supported by the die-carrier, a gage-plate arranged for sliding motion on the head-plate at the rear of and parallel with the die supported by the head-plate, screws supported by the head-plate near each end of the gage-plate, and means for turning said screws simultaneously.
5. In a b ending-machine, the combination, substantially as set forth, of a longitudinal die formed of sections separated by intervening notches, extending through the die and a counter-die cooperating therewith.
6. In a bending-machine, the combination, substantially as set forth, of a longitudinal die-holder provided with notches, sectional dies' removably secured in said dic-holder and separated from each other at the notches of the die-holder, and a counter-die cooperating with said. dies.
7. In a bending-machine, the combination, substantially as set forth, of a longitudinal die formed of sections with intervening notches, and a counter-die formed of corresponding sections and with corresponding intervening notches.
8. In a bending-machine, the combination,
.substantially as set forth, of a longitudinal die formed of sections with intervening notches, a long counter-die adapted to cooperate therewith, and sectional counter-dies removably secured to said counter-die and having spaces between them.
