DIE SHAPER.
Application filed August 31, 1921'.
To all whom it Magoo-710cm.
Be it known that 1, Elmer Bossnn'r, a citizen of the United States, residing in Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in a Die Shaper, of which the following is r specification.
This invention relates to an improved machine tool particularly designed for the roughing out of dies preparatory to finishing them and has for an object to produce such a machine, whereby the manufacture of dies may be greatly cheapened and simplificd, the time required to produce them being materially shortened and-less skilled. labor being required in their production.
This and other objects are attained in the machine described in the following specilication and illustrated in the accompanying drawings in which:
Fig. 1 is a fragmental side elevation of my improved machine, parts beim shown in section to disclose my invention to better advantage.
Fig. 2 is a front elevation, upon an. enlarged scale, of that part of my improved machine taken on the line 2'2 of Fig. l and looking in the direction of the arro Fig. is a view upon an enlarged scale of that part of my improved machine taken on the line 3-3 of Fig. 1 and looking in the direction of the arrows.
Fig. 4 is a view upon an enlarged scale of that part of my improved machine taken on the line el4 of Fig. 1 and looking in the direction of the arrows.
Fig. 5 is a view upon an enlarged scale of that part of my improved machine taken on the line 55- of Fig. 1 and looking in the direction of the arrows.
Fig. 6 is a view upon an enlarged scale of that part of my improved machine taken on the line 6-6 of F ig. 1 and looking in the direction of the arrows.
Fig. 7 is a plan view upon an enlarged scale of the die shown inposition on the machine in Fig. 1.
Fig. 8 is a sectional view taken on the line 88 of Fig. 7.
Fig. 9 is a view similar to Fig. 7, but showing the completed die.
Fig. 10 is a sectional view similar to Fig. 8 and taken on the line 1010 of Fig. 9, through the completed die.
In my improved machine, the elements of which are mounted on a frame 9, I have pro- Serial No. 497,209.
vided a forwardly and rearwardly movable table-carrying-block 10 upon which a transversely movable turret-carrying table 121 is main shaft 15, a drive shaft 16 and suitable driving mechanism located at the bottom of the frame, with an intermediate shaft 17 located beneath the main shaft. Shaft 17 is journalled at one end in abearing 18 at the rear frame 9 and at the opposite end in the hollow hub forming a sleeve 19 of a gear 20, the gear being in turn journalled in an intermediate bearing 21 at the upper part of the frame. Upon shaft 17 a cone pulley 22 is mounted, a driving belt 28' ex tending therefrom to the driving mecha nism. The rear end of shaft 17 is provided with a gear pinion 24: which meshes with a gear 25 on the rear end of shaft 15, where by shaft 15 is driven.
Upon shaft 15 a disc 26' is keyed. In this disc a bolt 27 is mounted for reciprocation in a radial slot 28 therein as shown in Fig. This disc, through its connection with shaft 15, drives a gear 29 which is loosely mounted on the shaft. The driving connection is effected in the following manner. In gear 29 a circular recess 30 is provided, with a branch 31 in which a nut 32, which is mounted on bolt 27, is adapted to enter. Thus by bringing bolt 27 into the branch 31 the gear 29 is driven and by moving it into recess 30 the gear is freed. Gears 2!) and 20 are of the same number of teeth and hence rotate in one to one ratio. Shaft 15 is journaled in a rear bearing 33 of tin frame and in a forward bearing 31. Beneath bearing 3 1- a guide plate 35 is pivoted at a pivot point 86, the lower end of the guide plate being connected to the forward end of a toggle link 37 at a point 38. The rear toggle link is connected at a point 11 i to pivot to the frame, the links being connected at a point 10 to form the toggle. Mounted to reciprocateflwithin guide plate 35 is a slide plate 4-2 which carries the metal cutting tool 43. This plate is reciprocated by a connecting rod 14 which, being attached to plate 42 by a bolt 45, is reciprocated by an eccentric 416 with which it connects by means of an eccentric strap 4.7. It will be seen upon reference to Figs. 1 and 2, that the connecting rod 44 is in the form of two connected yokes so connected to the bolt 45 and strap 47 at pivot points 48 and 49 that plate 35 may be swung outwardly when the toggle is operated, the vertical movement of the slide plate 42 combined with. the forward and backward movement of the guide plate 35, giving the tool 43 a Jeculiar movement which will be described. hereinafter. In order to operate the toggle I have formed the link 39 with forward extension 50 which is provided with a rearwardly turned pivot pin 51. This pin, by a connection like that provided at 49, is connected with a double yoked connecting rod 52 which at its upper end is similarly connected with a bolt 53 having its head located in a slot 54 in a disc like extension of gear 20. Adjustment of bolt 53 will bring the upper end of the connecting rod to the proper position in slot 54 to effect the desired forward movement of tool 43, and adjustment of bolt 45 in the slot 55 will effect the desired depth of entrance of the tool into the die, the former adjustment causing the toggle to operate to a greater or less degree as desired and the latter adjustment causing plate 42 to be lifted or lowered initially to govern its out, the amount of movement always being the same however because of the uniform throw of the eccentric. To facilitate manual operation of the tool in order to test its adjusted position before applying the power, I have provided a hand wheel 56.
The die to be produced, and a plan view of an example of which is shown in Fig. 7, is started by drilling through the metal in order to give an opening into which to start the tool 43. The die block is clamped in position and the machine is started after adjust ment of the tool movement to produce the desired results. The cut taken by the tool is governed by the operators manipulation of the turret 12, the table 11 and the block 10, and the proximity of the cut to the finish line 57 marked on the surface of the die block is governed by the amount it is desired to leave for hand finishing. In working through the metal out taken by the tool in response to the upward and downward, forward and backward move ment of plate 42 is such that the sides of the die divert downwardly as shown in Fig. 8, the out being somewhat curved to produce a recess which is bellied outwardly. Adjustment of bolt 53 toward or from the axis of shaft 17 will cause variation of the amount of outward bellying of the sides of the recess of the die by reason of the variation thereby of the amount of throw created by the toggle links 37 and 39.
Thus by this machine the roughing out of a die is accomplished quickly and by the working of the metal to within a short distance of the finish mark 5'? a small amount of handwork only is required to place the die in condition for tempering to the required degree of hardness and ready for use. In taking out the small amount of metal re quired for hand finishing the relatively sharp overhanging edge 58 of the die recess is all that remains for removal by hand. This, when removed, makes the die appear as shown in Fig. 10, the plan view appearing as shown in Fig. 9. Thus the die is amply provided with the necessary clearance and at the same time sutlicient of a cutting edge depth is left at the option or the operator to be amply strong for all purposes to which he die may be applied.
Having thus described my invention what I claim. is
1. A die shaper consisting of aframe, a drive shaft journalled in the frame at its top, an intermediate shaft j ournalled in the frame beneath the drive shaft, a guide plate beneath the drive shaft pivotally mounted at its upper end for forward and backward swinging movement of its lower end, a toggle connected with the plate for effecting swinging movement thereof when the toggle is operated, a tool-carrying side plate reciprocally mounted on the guide plate, an eccentric mounted on the drive shaft, means connecting the eccentric and slide plate for causing reciprocation of the plate when the drive shaft is rotated, and means operatively connected with. the intermediate shaft for causing operation of the toggle.
