METAL-SHAPING MACHINE.
Specification of Letters Patent.
Application filed April 1, 1908.
Patented June 15, 1909.
Serial No. 424,850.
T 0 all whom it may concern:
Be it known that I, PHILIP 3V. Jones, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful lrfetal-Shaping achine and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention relates to machines for shaping metal parts by rolls acting on the blank to forge the same to conform to a recess in the work-carrying or dieroll, and has particular reference to a machine adapted for the forming of tapered brake-shoe keys, but is not restricted to such use, as it may be employed for the shaping of any other articles for which. it is appropriate.
The object of my invention is the provision, in combination with. the work-carrying or die roll in a machine of this class, of simple and efiicient means for gripping and holding the blank while being operated on, which means is automatically movable at different redetermined points in a revolution. thereof both to release the work and to place itself in open position to receive another blank to be operated on, and also of means for succcssively operating on the blank as it is carried around with its roll to first bend it to form the headed end thereof and then to act thereon to gradually shape it to form the taper.
The operation, construction and arrangement of the parts of the invention are fully described in the following specification and illustrated in the accompanying drawings, in which,
Figure 1 is a top plan view of a machine embodying the features of my invention. Fig. 2 is a vertical longitudinal section on the dotted line x r in Fig. 1. 3 is a side elevation thereof. Fig. 4 is an enlarged view in perspective of one of the movable clamping jaws of the worl carrying roll, and Fig. 5 is a side view of the key when formed.
Referring to the drawings, 1 designates the base of the machine frame from which rise the two spaced pedestals or frame parts 2, Mounted intermediate these pedestals on the shaft 3, which. has its ends suitably journaled therein, is the work-carrying or die-r0114. This roll has its circumference formed with the annularly elevated portion 5 in the periphery of which are provided one or more circumferentially-extending taperedbottom grooves 6, three of which are shown in the drawings. The elevated portion 5 is provided with the radially movable sections 7, one of which is disposed at the deep end of each groove 6 and forms a jaw which cooperates with the contiguous end of one of the fixed parts of the portion 5 of the roll between which it is disposed. The jaws or sec tions 7 and the incuts or vacancies 8 in the portion 5 which said sections are intended to fill are preferably V-shape with their end lines standing substantially radial to the roll axis so that an inward movement of each jaw will effect a converging or gripping action of its ends with the ends of the incut 8. The jaws 7 are permitted to have limited radial movements in their recesses due to their inner ends projecting into the body of the roll and each being provided with a slot 9 through which a pin 10, that is inserted transversely through the roll and associated recess, extends. Each jaw has its gripping end faced with a hardened block 11, which is provided with a shoulder, as at 12, to act as a stop against which the inner end of the blank 13 is placed when being positioned in the roll, and is roughened without such shoulder to provide a better gripping surface.
The jaws 7 are caused to have a positive outward or opening movement at a predetermined point in a revolution thereof by rollers 14:, which are carried by studs 15 projecting from opposite sides thereof, working over cams 16, which overhang the roll 4 at the sides of its elevated portion 5 and are fixed against movement by tenons 17 pro jecting therefrom into mortises in the sides of the frame parts or pedestals 2, as shown in Fig. 1.
Cooperating with the die-roll 4 to form the blanks 13 in the desired shape are a plurality of rolls 18 (three being shown in the drawings), which are arranged between the pedestals 2 around a portion of the roll 4 and have their shafts 19 journaled at their ends in bearing-boxes, which are mounted in the pedestals 2 for radial adjustment relative to the roll 4. The rolls 18 have their inner surfaces arranged progressively nearer to the roll 4 to adapt them to successively act on a blank to gradually form the same in the desired shape, but instead of being the same size and having their axes adjusted nearer to the die-roll axis for such purpose, their axes are preferably arranged in the arc of a circle which is concentric to the die-roll axis and the rolls themselves are made progressively larger, as shown. As the rolls 18 are driven at the same speed by the like gears 20 on their shafts meshing with the larger gear 21 on the shaft with the die-roll, the arrangement of the rolls in this manner is quite an important feature in the perfect operation of the machine, as the gradual increasing of the size of the rolls not only disposes their inner surfaces nearer to the die-roll surface, but also prevents a slipping of the rolls 18 when in contact with the blank, which would otherwise be the case due to the lengthening ofllihe blank under the forging stress of the ro s.
In the operation of my invention the rolls are turned in unison by a turning of one of the shafts 19 or in any other suitable manner. As the rollers 14 of a jaw 7 in a revolution thereof with the die-roll 4 pass over the fixed cams 16, the jaw is moved outwardly to open position, as shown in Fig. 2, and an end of a blank 13 is then inserted into the opening 8 against the shoulder 12 of the jaw. After the rollers 14 leave the cams the jaw coacts with the first roll 18 of the set and is forced inwardly thereby to cause it to firmly grip the end of the blank to the end of the contiguous fixed part of the elevated portion 5 of the die-roll. As the movement of the die-roll continues the portion of the blank protruding therefrom is first bent over into the registering groove 6 in said roll and is then progressively acted on by the several rolls 18 to gradually forge or roll it out into taper form, as illustrated by the formed key shown in Fig. 5. Each jaw, on passing the last roll 18 of the set, drops by gravity to open position, thus releasing the formed article held thereby to permit it to drop from the die-roll when it has moved out of contact with the rolls 18. The key after being formed may be straightened by any suitable means.
I wish it understood that I do not desire to be restricted to the exact details of construction and arrangement of the parts of the invention shown and described, as obvious modifications will occur to persons skilled in the art.
Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is,
