HAMMER-DIE FOR DRILL-FORGING MAOHINES.
SPECIFICATION forming part of Letters f'atent N0. 437,840, dated October 7, 1890.
Appllcation filed Jenuary 8 1890.
T0 aZZ wh0m zt mauy concern:
Be it known that I, CLAUS VAN HAAGEN, of Chester, in the couny of Delaware and State of Pennsylvania, have invented an Improx*ement in Hammer Dies f01 Drill and Beamer Forging Machines, of whieh ehe following is a specification.
My invention has referentae to hammeedies employed in maohines for forging drills and reamers; and it eonsists in oertain improvemen's-s, all of which are fully sei: forth in the following specifioation, and shown in the aecompanying drawings, Which form a part thereofi My invention specifioally relates t0 asuitable die adapted to be used in a maohine for forging twist and ot-her drills and reamers, and in which maohine is employed two gripping-dies for holding the rod to be forged and two kammer-dies whieh operate in conjunetiou with the gripping-dies to forge in U16 grooVe, be :it spiral 01' straight.
The object of my invention is 130 produce a consuruotion of hammer-die whieh shall be eapable of withstanding t-he heavy duty and Wear. In praooice tl1e hammer-die strikes tl1e steel 10d abo1i's four hundred times a minut-e and eael1 tirne produoes a deoided deep forged portion of tl1e ultimate groove.
In oarrying out my invention I forrn tl1e hammer-die With a flattened nose having :its end rounded in all direotions, and preferably with a striking part slightly askew 130 the body of tl1e nose to oorrespond, in the ease of twist-drills, somewhat 130 he shape of the groove caused by its spiral 01 helical curve. When the die is to be used fo1 straight drills and reamers, this askew portion is made parallel or in line witl1 the body of the nose.
In making this hammerdie I cast it in a mold the lower pa1t of whieh is iron, so that when the metal fiows ino the mold the nose portion is ehilled and at the Same time oast smooth and in condition for use. The shank is oast in sand and is not so brittle as the nose.
In the drawings, Figure 1 is a perspeotive view of a set of dies, showing the relation of the hammer-dies eo the gripping-diea Fig.
2 is a perspective view of my improVed harm- Serial1l'm 336,243. (N0 model.)
mer-die. Figm 3 is an end View of same, and Fig. 4 is a sectional elevation showing tl1e mold in whieh the hammer=die is oasb.
A B are two grippingdies whiol1 have grooves forming the hole O for the 1'0d when ehe dies are plaeed together, and also the notehes 01 grooves 011 the sides whieh form the oblique holes or slots D ab right angles to tl1e hole O when tl1e said dies are placed together.
E E are the two I1LIIIUIIGPLIGS, Whieh are provided With the noses F, (bes/0 shown in Figs. 2 and 3,) which noses work througl1 the slots 01 holes D between the dies A B. The gripping-dies may be also used '00 forge the metal of the rod; but this oonstruction is 11011 claimed in this specifieation. If the dies are for use in forging straight drills and reamers, then the slot-s D are n0t oblique, as shown, bot are in the same plane wit-h tl1e hole C. The shauk portions of tl1e hammer-dies E are preferably of hard white cast-iron oastin sand I, wl1ile the nose portions F a1e of chilled cast-iron, Which has been castin the iron mold portion H, the sand I and i1on portion H forming the mold J 0f ehe sl1ape 0f ehe hammerdie. While the part II of the mold inoludes all 015 alle nose and shoulder,it is evident that; tl1e ehill might; be eonfined t0 the end of tl1e nose, if desired. By making tl1e ohilled portion extend somewhatbaok. provision for wear is made, and hence tl1e die in operation 1asts a long time eompared with what would result if the ehill inoluded only tl1e extreme point of the nose. The nose portion F has its ends rounded in all directionsbut also elongated, forming l1e part G and rounded ende f f. In ehe case of dies .for twist-drills tl1e part; G is made askew, as more elearly shown by the shading in Fig. 3, 110 eorrespond t0 tl1e peeuliar eurve 01": the groove being forged, and so as 130 leave the proper cutting and trailing edges on the drill. 'lhe askew construetion given to the end 01 point of the nose of the kammeedie is such as would oorrespond to the peeuliar eurvature of the grooves in the twistd1ill, whioh grooves noi1 only have the peou- 1iar crossseotion, but also are formed belieal, and necessitate the askew portion being made 110 correspond to the resultant between the helieal and the shape due 1:0 tl1e erosssection by said spiral grooves. The shank 0f 2-. As an article of manufacture,ahammerdie for drill and reamer forging maehines, 15 consisting of a body 01 shank terminating in a fiattened nose portion having its extreme end made With an elongated askew rounded portion, substantially as Set out.
In testimony 0f Which invention I have 20 hereunto set my band.
