Elbridge'V V. Hall, San Diego, Calif. Application September 16,1946, Serial No. 697,339

' Claims.

My invention relates to a joggle die, more particularly for use in sheet metal formin and the objects of my invention are:'

First, to provide a die 'of this class which is quicklyadjustable for depth of joggle without changing the fixed relationship of the dies in connection with the press to which they are secured; Second, to provide a'joggle die of this class which is provided withquickly changeable inserts, adapted to fit the contour or shape of various parts to'be joggled therein; H

Third, to provide a joggle die of this class having inserts in which various radii are meshed to fit and form a smooth pressure surface at the ioggle break in metal of various gauges;

Fourth, to provide a joggle die of this class in 'which depth adjustment of the joggle may be made with stepped-up blocks'or, shims;

Fifth, to provide a joggle die of this class which lends itself to mass production of sheet metal parts to be joggled; and

Sixth, to provide a joggle die of this class which is 'very simple and economical in construction, eflicient in its action, and which will not readily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, my invention consists of certain'novel features of construction, combination and arrangementof parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference'being' had to the accompanying drawings and to the characters of reference thereon forming a part of this application in which:

Figure 1 is a side elevational view of my jo's le die showing the male and female structure thereof 7 in superimposed relationship ready for use .in joggling parts; Figure 2 is a fragmentary top or plan view of the female structure of my joggle die taken from the line 2-2 of Fig. 1; Fig. 3 is a fragmentarybottom or'plan view of. the male structure of my joggle die; and Fig. 4 is a frag--v mentary sectional view taken from the line 4-4 of Fig. 1. V i

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The die holder I, ways block 2, die holder 3', step blocks 4 and 5, offset blocks 6 and I, forming dies 8, 9, I0 and II, wiper plates I2, bolts I4 and I5, gibs lIi and II, bolts I8 andISL andthe work holder constitute the principal parts and portions of my joggle die. f j

j The die holder Lis divided with a ways block engagingdovetailportions I'a slideably engaged with the ways block 2 and fixed in position by the said screws za'screw-threadedinto the ways block 2. The die holder I is'provided with a recessed portion Ib having an inclined surface Ia and. a step surface I d. Inwardly of the inclined surface I0 is a dovetailed slot Ie as shown in Fig. 4 of the drawing. Slideably positioned in the dovetailed slot le is the gib I6 in which the bolts I4 are screw-threadedly connected holding the offset blocks 6 in certain adjusted relationship with the inclined portion lc. The step block 4 is provided with conforming step portions meshing with the step surface Id of the die holder I, all as shown best in Fig. 1 of the. drawings. The forming dies 8 and 9 are provided with offset forming planes 8a and 9a arranged toconform to the offset planes Illa and I la of the forming dies I0 and I I,it being noted that the forming dies 8 and 9 are connected to the die holder I and offset block 6 respectively. The forming dies Ill and II are connected with the offset block .I and'die holder 3 respectively. The die holder 3 is provided with a recessed portion 3a having a step surface 3b and inclined surface 3c therein supporting'thestep block 5 and offset block I respectively. The gib I1 is similar in construction to the gib I6 described in connection with the die holder I and the bolts I5 are similar to the bolts I4 all as shownbest in Fig. 1 of the drawings. The, wiper plate I2.is secured at the outer side of the forming die 8 and is provided with an angular wiper portion In at its inner side arranged to engage the work when forming the same. As shown in Fig, 4 of the drawings, the forming die 9 is provided with a radius forming lip 9b arranged to engage and maintain the form of an angular part whenjoggling the same. The forming die .II arranged to cooperate with the forming die 9 is providedwith an internally radius portion I Ib arrangedto support the inside of the part being joggled. The work holder 20 is secured in connection with the die holder 3 by a clamp bolt 20a and this work holder 20 is arranged to engage theouter side of the .work for holding the same adjacent to the forming die II inproper' alignment with the forming die 9. It will be noted that the forming dies9 and I I respectively areprovided with dovetailed locking portions and Na which interlock in connection with the die holders 2 and 3 respectively. The offset blocks 6 and I are supported by the gibs I6 and H which 2,479,161 7 i 3 4 is clamped in connection with the forming die I l of die holders movable relatively to each other, by the work holder 20 secured to the die holder recessed portions in said die holders having 3 by the bolts 20a. The ways block 2 and the stepped surfaces in a row inclined to the vertical bottom portion of the die holder 3 are secured therein and opposed inclined planes, offset blocks in connection with the head and the anvil of a 5 mounted on said inclined planes having horipress respectively, and the die holder I is moved zontal surfaces, step blocks engaging said offset longitudinally of the ways .block 2 in relationship blocks and said step surfaces of said recessed porto th die holder 3 for proper alignment of the tions, and forming dies in connection with said forming dies 8 and 9 relatively to the forming oifset blocks at the horizontal surfaces and dies Ill-ands when set for a c'erta'indepthrof l0 parallel theretor j joggle, dependent upon, the spaced relatidnhot the 3311i af'joggle die of the class described, a pair forming surfaces 8a and 9a of the forming dies of die holders movable relatively to each other, 8 and 9, cooperating with the forming surfacesi. recessed portions in said die holders having I (la and i la of the forming dies H] and I I respecstepped surfaces in a row inclined to the vertical tively.
