To all whom it may concern:
Be it known that I, Tnnonon CHRISTIAN SoHELo, a subject of the German Emperor, residing at Hamburg, Germany, have invented new and useful Improvements in Machines for Bending Metal Plates, of which the following is a specification. 4
"This invention relates to a machine of novel construction for bending metal sheets or plates, the machine being more particularly adapted for shaping heavy boiler plates and similar articles.
means of a hydraulic plunger 10 movable in a cylinder 11 to which a suitable pressure medium may be admitted through pipew', communicating with a valve box '11. Plum ger 10 is by link 12 connected to a slide 13' carrying rollers ll and 15. Rollers 14 engage a pair of rear projections 16 formed on beam 11, while rollers 15 engage inclined guide ways 17 ofupper frame-section f. It will be seem that when plunger 10 is raised, slide 13 will also be raised through link 12, to advance beam a, toward roll 6. owing to the engagement of rollers 15 with guide ways 17 Roll 1), is provided with a lower trunnion .b', and an upper trunnion b rotatable 1n bushings h, h, which are fitted into lower frame-section f, and upper frame-section f, respectively. Trunnion 5 has an eye on, adapted to be engaged by a suitable hoisting dev1ce, (not shown), so that roll I), together may be lifted out of frame f, F. Trunnion b, is provided at its bottom with a key I)", adapted to be received within a corresponding roove d of a collar d, integral with a s aft d.
bushing f, fitted into a stepped cylinder f which is secured The latter to frame 1, by screws f At its lower end, shaft d, carries a beveled gear wheel 0, meshing into a similar wheel is, fast on power shaft 1.
The metal sheet 2, to be bent, is introduced between beam a, and roll b, and rests upon a series of rollers y, freely movable upon bed plate 1'. The rotation imparted to roll I), by shaft (1, wheels e, 70, and power shaft Z, will cause the sheet 2, to be fed in the direction of the'arrow, (Fig. 2). During this movement, sheet a, is forced against roll I), by suitable pressure rollers 79, one of such rollers being shown in the drawing. Roller 79, is journaled within the squared head p of a hydraulic plunger ,1), which is slidably mounted within a corresponding bore a, of beam a, a stntling box t, preventing the escape of the pressure medium. Bore s, is by duct 8 and pipe 8', connected to valve box '0, hereinabove referred to. Itwill be seen that by properly operating suitable valves controlling pipes w, 8', and contained within box '0, beam at, and pressure roller 7), may be independently advanced toward roll I).
In use, the sheet 2, to be bent, is first introduced between roll 6, and pressure roller p, whereupon the latter is advancedtoward roll I), to press the sheet 3, against the same. Roll 1), is then slightly rotated to feed the sheet forward and is again arrested. Press beam or, is now advanced to forcethe' sheet against roll I), and bend part of the same intothe curvature desired. Beam a is then retracted and roll I), is again partly rotated to interpose an unbent sheet-section between beam a, and roll I), whereupon beam (1, is again advanced, which operation is repeated until the entire sheet has been properly shaped. Roll 7), and bushing h, are finally lifted out of the frame by a suitable hoisting device engaging eye m, to permit the ready removal of the sheet.
I claim:
1. A machine of the character described, comprising a roll, a ress beam, means for advancing the press cam toward the roll, a pressure roller carried by the press beam, and means for advancing said pressure roller toward the roll independent of said beam.
2. In: a machine of the character described, a roll having upper and lower trunnions, a key formed on the lower trunnion, Signed by me at Hamburg, Germany this a shaft having a groove which is adapted to njnt-hday of March 1909. receive the key, and means for rotating the shaft, combined with a press beam, a pressure roller carried thereby, and independ- Witnesses: entmeans for advancing said beam and AUGUST WENK, 1'olle1' t0wm.'d the roll.
