The invention relates to the manufacture of cup-shaped members and refers particularly to the apparatus for forming cup-shaped members. One of the objects of the inven-` '5 tion is to so construct the apparatus ythat the -cup-shaped members are expanded by liquid therewithin. Another object is to construct the `apparatus with vrelatively movable die sections :which'determine in one position the m contour ofthe cup-shaped members and 'which also permit of the removal of the cupshaped members after. being formed. Further objects of the invention reside in the novel features of'constructionand combina-l Vn, tions and arrangements of parts as more y 20 invention;
. Figures 3 and 4l are cross sections respec-I ltively on the lines 3-3 and 4-4 of Figure 2.
The apparatus herewith shown is designed f particularly to form-the front sections of g5 wire wheel hub shells and has the stationary die shoe 1 within which the die holder2 is vertically slidable. Fdr maintaining the base of the die holder normally spaced above the base of the die shoe, I have lprovided the 30 rubber pad 3 which is locatedbelow the die shoe 'and the vertical rods 4 extending through the base of the die shoe and abuting at their lower ends the pad and at their upper endsthebase of Ithe'die'holder. 5 is 35 the sectional die comprisingA the. annular series of die sections 6 having outer inclined faces 7 for slidably engaging downwardly and inwardly inclined inner faces 8 upon the die holder 2. These die ksections have co- 40 yoperating horizontal wedge-shaped inner ends 9 each having an inner face corre'- sponding to the desired -completed contour of the upper' part of the cup-shaped member 10. When these die ,sections are in their t e stops 11 upon the base of the die holder 2 and engageable with the lower ends of the die sectionsthe inner lends of the die sections form a continuous die` with a continuous :50 inner *face 12 is a second die support-ed upon the base of the `die shoe 1 and concentrically of the sectional die 5,.this second die being adapted to-extend upwardly within the sectional die and having an upperl face corresponding to the contour of the remain- 'ing lower part of the cup-shaped member.
The cup-shaped member 10 when placed Within the apparatus has, as shown in` Figure 1, the vbottom 13, the main cylindrical portion 14 connecting, into the bottom, the outwardly and upwardly annular flared portion 1 5 connecting into the main cylindrical portion and the enlarged cylindrical portion 16 connecting into the iared portion. The die sections 6 at this time are held in elevated position and separated vfrom each other by means of thev pad 3 acting through the vrods 4 and the flared portion 15 of the. ycup-shaped member 'engages and is supn ported by the correspondingly dared shoulders- 17 upon the die sections. Vlin the present instance the cup-shaped lmember when placed within the apparatus is iilled with .a predetermined amount of liquid yauch as oil, this-amount being sufficient to expand. the cup-shaped member against the die sections 6 and die 12. 18 is a holder suitably secured to a vertically reciprocable ram of a press. 19. are pins carried bythe holder and vertically reciprocable relative Ithereto, these pins #being yieldably forced downwardly relative to the holder by thecoil springs 20. The pins are" so located that therev is one pin engageable with the upper end of each die section 6.
`As shown, each pin is slidably mounted in the, bushing 21 secured to the holder, this bushing projecting downwardly. below the holder and having the diametrically opposite slots 22 terminatin short of the lower end ofthel bushing and engageableby the ends of the transverse pm 23 extending through the pin 19. The bushing also receives a coil spring 20. 24 is a plunger secured to the holder l18 and having the mainf cylindrical portion 25 for fitting the venlargedy cylindrical portion 16 of the cupshaped member, the tapered annular shoul der 26 for fitting the flared portion 15 of the cup-shaped member and the reduced cylinp drical portion 27 'for fitting the main cylindrical portion 14 of the cup-shaped member, as shown in Figure 2 of the drawings, the
lower portion 28 of thel punch is adapted to '5. enga e the bottom 13 .of the cup-shaped mem r land to cooperate with the die 12 to serve the central portion of the bottom from the remaining'partof the cup and form the hubcap hole. v v
In operation and with'the parts as shownin Figure 1, downward movement of. the ramv and the holder- 18 first carries `the die Asections 6'downward1yltotheir lowermost l-member ,o cylindrical portion 27 lof the mil'member` to move outwardly a ainst the in'- ner face of the lower part of t e cup-shaped member to expand the same against -the diev sections 6 an die 12. Then the lower end of the plunger 24 contacts with the bottom so ofthe cup-shaped 'member and severs the central portion thereof. This central portion however,V is not rcompletely removed from the remainingpart of the bottom so that the liquid can escape. Q The cup-shaped member is lnow completely fashioned and s moval of f -.10 provided the knock out pin 29v whichex.-y
.collar 30 engageable with the central porma be removed `and the central portion of ,its ttom knocked out. f' f For the lpurpose of facilitating the ree cup-shaped member, I have tendsaxially through the die 12 and `is provided at vits upper end with the knock out -tion of the bottom of the cup-shaped member. lThe knockio'u'tpin 29,'.is actuated by' he ram upon its upward movement by suitable means such`X as they pull bars 31 con-f ne'cted ,to the ram and the cross'barf32 connected to the pull bars and' knock out pin.
As a result, u ward 'movement 'of the ram' first ermits t e die' sections 6 to ymove up.
,ward y under'the influence of the Lpad 3. Then the'knock out pin 'is pulled upwardly turn :lightly raises t to raise the cup-shaped member which in e die sections to `provide cient clearance for" the cup-shaped member to pass, upwardly therethrough.y After; the -cup-shaped o member has passed u"wardly therethroughfthese die sections 00 t en gravitate back to their ositions determined b \the-pad 3- Aand t e apparatus is noworea y to ireceive another cup-shaped 'WhatI-Lclaim. as my invention is shaped members, for receiving a cu -shaped member, #of means engageable wlthin "said cu` -shaped member for forcing liquid outwardy thereagainst to expand the same, and means for a portion from the bottom of the shearing cup-shaped member.
