May 17, 1938. c. s. SWANSON WATER COQLED DIE FOR FORMING DISK WHEELS Filed July 18, 1936 Patented May 17, 1938 UNITED STATES arisen WATER COOLED DIE FOR FORMING DISK WHEELS Clarence S. Swanson,
Standard Forgings Corporation,
Chicago, Ill., assignor to Chicago, 111.,
a corporation of Delaware Application July 18,
4 Claims.
This invention relates to dies for forming forgings, and particularly towater cooled dies. The dies herein shown and described are adapted for forming disk wheels, but the invention is not limited to the specific form illustrated.
The main object of the invention is to provide means for cooling the forming dies so that the cooled dies will cause the forging being formed to cool rapidly and act as a quench on the forging. The fast cooling serves as a quenching process from the finish forging temperature of approximately 1650 degrees Fahrenheit, rapidly cooling the forging below the critical range to approximately 1200 degrees Fahrenheit and fixing the normal grain size in the steel finish forged at the 1650 degree temperature. In consequence of this cooling, high strength in the steel forging is attained without increasing hardness.
A further object of the invention is to provide water cooled dies efficient for their intended purpose, in which circulation of water is efficient and uniform, and which may be constructed and assembled economically.
The forming dies herein shown, exclusive of the water cooling features, are the subject of. my co-pending application, Serial No. 78,860.
In the drawing:
Fig. l is a vertical sectional view of a pair of forming dies embodying my invention.
Fig. 2 is a horizontal sectional view, in the plane of the line 2-2 of Fig. 1.
In that embodiment of my invention shown in the drawing, the upper die comprises two members, I0 and II, and the lower die two parts, I2 and I3. The upper die is mounted in a reciprocable support (not shown) and the lower die rests on a fixed support I4.
- awn.
Certain features of construction herein shown, such as the housing I5, spring supported drawing ring I6, trimming edges I1 and I8, guiding means I9, 29, and the special contour of the faces of the dies, are the subject of my aforementioned copending application and need not be herein described in detail because the present invention is not dependent upon them.
The upper part IU of the upper die has a central boss 2! which has a flat surface adapted to bear on the complemental central boss 22 of the lower part II of said die. The part III has a peripheral offset edge 23 which is complemental to the edge 24 of the part I I. Between the contacting centers 2!, 22, and peripheral edges 23, 24, the die members In and II are recessed to form an annular chamber through which water circulates for cooling the face 25-of the upper die.
1936, Serial No. 91,319
The part II is so recessed that the floor of the chamber preferably follows the contour of. the faces 25, leaving a water cooled shell between the forming surfaces of the die and the chamber.
Within the chamber formed between the parts I0 and II of the upper die are a plurality of radially disposed baffles, the bafiles 26 being preferably integral with the die part Iii and the baffles 21 with the part II. A partition wall 28 extends radially across the chamber between the water inlet 29 and outlet 30 in the side of the die part I ll. The baffles 26 and 21 are alternately arranged and extend vertically between the die parts I0 and I I so that the water circulates in a zig-zag course, as clearly shown in Fig. 2. The presence of the baffles 26 causes the water to flow toward the center 2I-22, and the baffles 21 direct the water in an outward radial direction, whereby the shell above the forming surface 25 is efficiently cooled. The disposition of the baffles and partition wall on the respective die parts Ill and Il permits said parts to be constructed and assembled in a convenient manner.
The lower die members I2 and I3 are also provided with central bosses 3 I, 32, which correspond with the upper die bosses 2I, 22, heretofore described. Peripheral edges 33, 34 are similar to the meeting edges 23, 24. The die members I2 and I3 are also recessed to form an annular chamber beneath the forming surface 35, leaving a water cooled shell between said surface and the chamber.
Baflles 36 extend inwardly from the die member I3 and baffles 3'! extend radially from the center of the die member I2. A partition wall 38 extends across the chamber between the inlet 39 and outlet 4|]. The water circulates in the lower die in a zig-zag course as heretofore described in connection with the upper die.
Changes may be made in details of construction without departing from the scope of my invention and I do not intend to be limited to the exact form shown and described, except as set forth in the appended claims.
I claim:-
1. Apparatus for forming disk wheels, comprising a reciprocable die and a stationary die, the lower surface of the rcciprocable die constituting a forming face adapted to cooperate with. the upper surface of the stationary die, an an.- nular chamber in the reciprocable die above the major part of the disk wheel forming face and spaced from the said face by a relatively thin shell which extends between the center and the Periphery of the die for a distance substantially equal to the radial extent of the disk-forming face, and means for circulating water through said chamber.
