MACHINE FOR FORMING METAL BLANKS.
Specification of Letters Patent.
Patented Apr. 12, 1921.
Application filed November 1'7, 1919. Serial No. 338,577.
To all whom it may concern Be it known that I, EDWARD J. PAQUE, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Machines for Forming Metal Blanks, of which the following is a specification.
An object of my invention is a machine for forming metal blanks, which enhances the character of the metal, and produces well-trimmed blanks.
Another object of my invention is to produce a machine of simplified construction for making metal blanks.
These and other objects are attained by the means described in the specification and illustrated in the accompanying drawings in Figure 1, is a front elevation of a machine embodying my invention, parts thereof being removed to expose the parts in the rear of them.
Fig. 2, is a detail view partly in section and partly in front elevation of the dies and punches of my machine.
Fig. 3, is a detail View partly in front ole-- vation and partly in section, and upon an enlarged scale of one of the dies of my machine.
Fig. 4-, is a view similar to Fig. 3, of the other die of my machine.
The machine embodying my invention comprises a die A and a hydraulic punch B, which cooperate in removing a central plug from the circular disk to form a ring blank, and a die D and a punch E which cooperate in pressing from the ring blank a ring F of more finished construction.
This machine is intended to be used in forming rings for the manufacture of ball races, etc. These rings have heretofore been forged. When the metal is'cut, a steady pressure is exerted upon the metal, whereby the character of the metal is enhanced in that the grain is refined and the strength of the metal is increased.
which forms a way along which the blanks are moved from the die A to the die D.
Die A has a central opening a substantially of the diameter of the punch B and surrounded with cutting edges. In the base is an opening a in alinement with the opening 01?, for the removal of the plug 72. which is out from the disk H by the die and punch A and B. Die D has a central opening (5 of a diameter slightly less than that of the ring which has been formed by the die and punch A and B, and has cutting edges surrounding this opening. Punch E has a tapered end 6, the lower end of which is of a diameter slightly less than the hole in the ring and is adapted to center the ring upon the die D.
In operation a metal disk H is placed upon the die A, and a ring II, which has been previously formed by the die and punch A and B, is placed on the die D, then the head G is lowered by hydraulic pressure, the punch 13 presses the plug it from the disk H. and the punch E presses the ring F from the ring II. Upon the return of the head G, the ring II, which is formed from the disk II, is moved along the way a to punch E, and another disk II is placed on die A. The plug it and the ring F being removed from the table, the step previously described is repeated.
What I claim is 1. In a machine of the character described the combination of a die, a hydraulic punch adapted to cooperate with the die for removing the center from a disk to form a ring, 'and a second die, a hydraulic punch having a tapered end adapted to be projected through the center of the ring and to center the aforesaid ring upon the second die, and to cut a ring from the center thereof.
2. In a machine of the character described the combination of a die, a punch adapted to cotiperate with the diefo-r removing the center from a disk to form a ring, a second die, a punch having a tapered end adapted to be projected through the center of the ring and to center the aforesaid ring upon the second die, and to cut a ring from the center thereof, and a hydraulic press adapted to actuate the punches.
In testimony whereof, I have hereunto subscribed my name this 12th day of No-
