Ambrosius, Lakewood, Ohio, assignor to The Standard -0il Company (0hio),-Clcve land, Ohio, .a corporation of Ohio Application May ss, 1936, serial No. $1,635 'i claims.- (climi-'19 This invention, relating to sheet metal ware manufacture, has more particular reference to the production of metallic structures` on the order of pistons such as for grease cartridges. etc; and
it is among the objects of the invention to facilitate accurate manufacture of such articles. Other objects and advantages will appear as th'e description proceeds.
To the accomplishment of the foregoing and `related ends, the invention, then, comprises the features hereinafter fullyldescribed, and particularly pointed out in the claims, the following description and the annexed drawings ysetting forth in detail certain illustrative embodiments of the invention, these being indicative however, of
but a few of the various ways in which the principle ofthe invention may be employed. In said annexed drawings:-
- Fig. 1y is a vertical sectional view of die mech-- .20 anism contemplated in the invention; Fig. 2 is a plan v iew thereof Fig. 3 is a section corresponding to Fig.'1, showing the parts in closed position; and Fig. 4 is a transverse section taken on a plane substantially indicated by line IV--IV,
25 Fig. 1.
In an assemblage of die elements, as indicated in Fig. 1, etc., die blocks 2, 8,7`are arranged for reciprocatively opposed motion so as to close together and be separated by some suitable 30 means, as for instance a reciprocating press. me-
chanical or hydraulic, the respective die' blocks being securedto the-jaws P thereof. Fixed tobne of said die blocks, 8, is a central stud s, having a cylindrical body portion 5 and a taper cam 4po'r- 5 tion 8. The stud may be secured to the die block by suitable means, for instance screws 'I.V About the stud and reciprocable thereon is a follower plate 8 capable oia limited excursion of movement, being urged in a direction away from the 40 block by spring means 8. To limit the movement of such follower plate, a shoulder retaining means or ring s nightly overnanging the plate, 1s suitably secured to the die block 8, such as by screws I8. On the follower plate is an inner set of 5 radially movable die sections I2 having raised central portions I8 with die surfaces peripheral f ly thereon. The movable die sections I2 are actu-` sections i8,- these being reciprocativeiy mounted...
v conveniently on the die sections I2, and having 'lvrlnt means i8 therebetween, asin recegses ,for
normally separating the inner' and outer die sections. A suitable retaining means or guide, as retaining ring I1 prevents disassembly, while permitting radial reciprocating movement of the die sections I8. On the outer ends of the die sec- 5 tions I5 are cam or beveled surfaces I8, andthe other die block 2 carries an actuating cam therefore,such as cam. ring 28, internally beveled as, at 2| to coact with the Jcam* surfaces I8 when forced thereagainst. The actuating cam is 10 suitably secured to the die block 2, as by screws 22. From the structure this far it is seen that n when'the die blocks 2 and 8 are` forced into apposition by the press the cam 20 riding ontp the cam ends I8 of the outer set of die sections 15 beyond the springs 26. Y Centrallyof the follower l ring 2l is a center follower 21,4havinga blank-engaging center stud 2l. This follower is also normally urged away-from the die block by suitable means, as spring means 88. To properly limit the range of motion of the center follower, a shouldered Aretaining means or ring 8| is arranged in relation, and held to the die block by suitable means, as screws'82. l With the pressi ready for operation, and the dies in position as in Fig. 1, a sheet metal blank is fed linto the die cavity by suitable means, hand feed or automatic, the detail being immaterial here, and with the closing of the dies, the coacting die surfaces shape and true the sheet metal blank to nal nished form F shown in Fig. 3. With 40 the separation or opening of the dies, vthe sheet .'metal, piece or formed piston is free, and is dis- A' .charged suitably, manually or by an air blast -through an air duct ain the die block 3. .A new blank is fed, and the operation repeated.
- Other modes lof applying the principle of the invention may be employed, change being made 4as regards the details described, provided the features stated in any of the followingv claims, or
the equivalent of such, be'employed. 60
