Wyman and Joseph M. Malik, Toccoa, , Ga., assignors to R. G. Le Tourneau, Inc., Stockton, Calif., a corporation of California ' Application November 17, 1942, Serial No. 465,860 5 Claims. (Cl. 78-96) 1 , wherein the forging'drive-out rod is power ac This invention relates in general to forging ~ dies and mounts therefor, and the invention has tuated. ' Figure 4 is a side‘ elevation of a forging die for its principal object the provision of a forg ing die and mount assembly which is arranged to facilitate placement of the work‘in the die, and mount assembly, illustrating an embodiment wherein the die tip-over mechanism'is power and removal of the forging from the die after actuated. ' , Referring now more particularly to the char acters of reference on the drawings, and at pres ent to the embodiment of Figs. 1 and 2, the forg ing die and mount assembly comprises a, horizon the forming operation; the device being espe cially designed» for use in power forging presses. A further object of this invention is to pro vide a forging die and mount assembly in which the die is normally upstanding and opens up tal elongated base 1 adapted to be removably secured to the bed 2 of the forging press by means wardly; said die being mounted for tip-over move ment from said upstanding position to a position of bolts 3. An upstanding die holder 4 is nor mally seated on the base I adjacent one end opening laterally, whereby to permit the ready thereof; said die holder surrounding and sup porting an upstanding cavity die 5 which includes insertion of the work in the die, or the removal of the forging therefrom, particularly when the space between the head of the power press and a vertical work receiving bore 6 open to the top the top of the die is limited, or in any instance where horizontal or lateral removal of the forg lofsaid die. position. movement of the die holder to a position with the " ' ' The die holder 4 and the supported die 5 are ing is more desirable.

A stop H on the base limits tip-over die bore 6 opening horizontally. A horizontal longitudinally extending forging drive-out rod I2 is supported above the base 1 the die is of cavity type, normally upstanding and opens upwardly, being mounted for tip-over 30 beyond the die holder, in a direction opposite to the direction of tip-over movement of the lat movement from said upstanding position to va ter, by upstanding longitudinally spaced guide position opening laterally; the die having a bot tom opening, and the assembly including a mov It is also an object of this invention to pro vide a forging die and mount assembly in which brackets. able forging drive-out rod normally mounted clear of the die but adapted to project at one end through said bottom opening and to strike the forging when the die is in tipped-over position, at ' » > ' ' The 'bottom of the die is formed with a cen tral port M of a diameter less than the diameter of bore‘ 6, and the rod I2 'alines with and is adapted to project through said port when the die holder and die'are'iii'tipped-over position. said drive-out rod being manually actuated in At the end opposite the die holder the rod I2 one embodiment of the invention, and power ac tuated in another embodiment of the invention. 40 is formed with an enlarged head It, and a shock absorbing compression spring l6 surrounds the A further object of the invention is to pro rod [2 between head l5 and the adjacent guide duce a simple and inexpensive device and yet bracket i3. As is shown in Fig. 1 the drive-out one which will be exceedingly effective for the rod i2 is normally clear of ‘the die holder 4. .purpose for which it is designed. The die tip-over arrangement comprises a bell These objects we accomplish by means‘ of such 45 crank lever ll-l pivoted at l8'in connection'witn structure and relative arrangement of parts as the base I for ‘swinging movement in a vertical plane- lengthwise of'sai'd base; one leg is of the will fully appear-by a, perusal of the following speci?cation and claims. ' In the drawings similar characters of reference indicate corresponding parts in the several views: Figure 1 is a side elevation of the forging die mount assembly, illustrating an embodiment wherein the die tip—over mechanism‘ and the forging drive-out rod ‘are both manually actu ated. - ~ ‘ ' ‘ " Figure 2 is a fragmentary longitudinal sectional elevation showing the die in tipped-over posi-‘ bellcrank I“! being relatively short and normally to projecting upwardlmwhile' the other leg 20 is normally substantially horizontal and is elon gated to form ahandl'e. vA rigid link 2| is pivot ‘ally connected‘ between the upper end of leg 19 and the adjacent side of the die holder 4 at a 55 point intermediate the ends of, and in tip-over ‘ relation to the latter. - Operation tion and the forging drive-out rod in use. Figure 3 is a side elevation of the forging die In the present instance, the die 5 is of the type and mount assembly, illustrating an embodiment used in connection with the formation of cylin~ 2,408,542 3 4 drical forgings P, such as headed pins. After the forging P has been formed by the press in the upstanding die 5, the hand lever 20 of bell means are found desirable, the same may be in~ Thereafter corporated in this embodiment of the invention and can be of the manually actuated type shown in Figs. 1 and 2, or the power actuated type, shown in Fig. 3. From the foregoing description it will be read the operator strikes the head E5 of rod l2 with a sledge hammer, which causes said rod to project substantially ful?lls the objects of the invention at the other end through die port Mr and force, as set forth‘ herein. crank H is swung upward, which causes the die holder to tip over to the laterally opening posi tion shown in dotted-lines in Fig. 1. ily seen that we have produced such a device as fully strike the adjacent end 01’- the forging P, 10" driving the latter out of the die. The spring I6 serves as a shock absorber tor the blow imparted ; to head 15. After the forging has thus been removed from» the die the hand lever .28 is returned to normal 15 horizontal position, which causes the die holder and die to likewise be returned to upstanding position for the next forging operation. In the embodiment shown in Fig. 3 the die. holder ll‘and die 5. are mounted on the. base I, as 20 above described, and are tipped from upstanding to. laterally opening position by a link, 2m and a bellcrank lid arranged in a manner similarto . In this embodiment, however, the, forging may be resorted to as do not form a departure from the spirit of the invention, as de?ned by the appended claims. . Having thus described our invention, what We claim as new and useful and desire to secure by Letters Patent is: 1_.
