DIE FOR FORGIINIG AND SWAGING.
SPECIFICATION forming part of Letters; Patent No. 259,263, dated June 6, 1882,
' Application filed January 10,1882. (No model.)
provements in Forging and Swaging Dies, of
which the following is a specification.
This invention relates to the construction of forging and swaging die-blocks provided with several matrices, to supporting cases therefor and devices for securing said die-blocks therein, the object being to obviate the inconvenience and loss of time occasioned by the frequent stopping of forging and swaging machines for the purpose of replacing Worn-out die-blocks with new ones when said machines are being run upon one description of work, to provide against the liability of said diebloeks to be broken by use, and means for properly sustaining said die-blocks in'working position and for substituting quickly new matrices for those which have become too much worn. V
In the drawings forming part of this specification, Figure 1 is a perspective view of a swaging or forging die-block and its supporting-case constructed according to my invention. Fig. 2 is a view of said die-block re moved from its case. Fig. 3 isa view of the die-block bolt and nut. Fig. 4 is a view of the die-block case. Fig. 5 illustrates the relative working position of a pair of die-blocks with their inclosing cases.
Fig. 6 is a vertical section of said die-block' and case, the former being in working position in the latter and the die-block bolt being shown in full lines.
In the drawings, a is the die-block. b is the die-block case. 0 is the die-bolt. o is the nut. '11 is a spline-key.
Like letters indicate like parts in the several figures.
Heretofore in operating forging and swaging machines, either for hot or cold work, dies of rectangular form have been used, being keyed into suitable blocks in the machine; but in cases where the description of work to be done demands great rapidity of blows, together with considerable force of same, it is found that the durability of rectan gular-shaped I dies is very short, owing to their frequent breakage. The aforesaid inconveniences are obviated by the employment of a die-block and supporting devices therefor, constructed as herein shown and described.
The die-block 01,1 make of cylindrical form, and upon and in its peripheral surface I sink several matrices, a). The die-blocks herein illustrated are such as are adapted to the work of swaging and forging cylindrical rods; but other descriptions of work may be advantageously done with these die-blocks by providing them with properly-formed matrices.
A bolt-hole, as shown, is made through said die-block longitudinally, and in one side of said hole is formed a spline-groove, m, Fig. 2. A bolt, 0, is fitted to said bolt-hole in the dieblock a, and its extreme screwed end is squared, so that a wrench may be applied thereto for the purpose of turning it, and it is provided with a suitable nut, 0, and washer 0. Said bolt 0 is, like the bolt-hole in die-block a, prpvided with'a spline-groove to'match the former, bothtogetherbeingadaptedtoreceivethecylindrical spline-key '0, said bolt and die-block receiving each about one-half of said key. The length of said bolt under the head is such as to adapt it to reach through said die-block and beyond the rear side of the die-block case b, as in Fig. 6.
The die-block case b is made of a block form, and is provided with a die-block socket, h, of the proper depth and circumference to receive the die-block a therein, encircling its entire periphery, excepting so much thereof as will leave one of its matrices a: and a portion of said die-block standing slightly above one side of said case, and having a bolt-hole at the base of said socket h, coincident with that through said die-block. Said die-block a is turned and ground to a perfect fit in said socket in the case b, and the bolt 0 being inserted through said die-block and case, as shown, the two are rigidly secured together, and by turning back nut o die-block a may, by applying a Wrench to the squared end of bolt 0, be turned in socket h to bring the matrices m, oneafter the other, to the upper side of the die-block and above .the side of the case b, as in Fig.- 1, there-- by providing means for expeditiously bringing a new and unworn matrix to the operative face of the die-block a by simply turning the latter in its case, and then rescrewing the nut o to bind the die-block and case firmly together, as aforesaid.
The above-described manner of changing or revolving a cylindrical die-block to bring a fresh matrix to its working side obviates the more slow process of taking out a worn die and replacing it with a new one, and enables the operator to run his machine much more continuously.
In addition to the above-described advantages appertaining to die-blocks which are constructed as herein shown and described is -still another no less important, and that is the provision made against the almost constant breaking of (lie-blocks which are used in rapidly-worked hammers and compressing-machines by making the die-blocks of such form as permits of grinding them into a case, b, and to a perfect fit therein, so that saidcase becomes such a rigid die-block envelope as to make it nearly impossible to fracture the dieblock under any ordinary working conditions, thus saving no inconsiderable expense in the maintenance of dies for said machines.
In placing said die-block cases and dieblocks in forging and compressing machines they occupy the relative positions shown in Fig. 5the exposed portions of two die-blocks turned face to face and bringing two of the matrices on the two die-blocks opposite each other, as there shown.
The cases I) are secured in said machines in the usual manner-one in a fixed position and the other movable; or both may be movable.
I am aware that it is common for blacksmiths use to construct a revolving swage with an assortment of dissimilar grooves out upon its surface in the direction of its axis, as shown in Browns patent of March 23, 1869, and I do not claim such construction; but
What I claim as my invention is- 1. The within-described improved forging die-block and supporting-case therefor, consisting of the cylindrical die-block having a series of matrices upon its peripheral surface, a die-block case enveloping nearly the entire periphery of said die-block and fitted tightly thereagainst, and an axial bolt for securing said die-block firmly in a fixed position in said case and for turning it therein, all combined and operating substantially as set forth.
2. The within-described forging die-block and supporting-case therefornamel y, the cylindrical (lie-block having a series of matrices upon its peripheral surface, and a die-block case enveloping nearly the entire periphery of said die-block and fitted tightly thereagainst, theyjointly operating substantially as setforth.
