No. 131,916 4 Claims. (Cl. 29-33) The invention herein disclosed relates to the manufacture and assembly of parts made from separate lines of stock, such as two separate lines of strip material.

This patent is a continuation in part of copending patent application Serial No. 837,912, filed September 3, 1959, now abandoned.

Objects of this invention are to provide simple practical mechanism combined in one compact machine, for feeding in stock at opposite ends of the machine, independently forming or otherwise shaping or acting on such stock to create identical or difierent kinds of parts and then as a continuation of such operations, assemblying such parts in completed units and discharging the finished product of the machine as completed products made up of such manufactured parts.

These objects have been accomplished by a novel combination and arrangement in which the strips of material, formed to desired shape are advanced in opposite directions in laterally offset opposed relation, severed at the ends into the parts which are to be associated and then these formed and severed parts in such opposed relation are brought together and secured so, as by stitching, staking, riveting, welding or adhering or otherwise fastening the parts together.

The drawings accompanying and forming part of this specification illustrate a practical commercial embodiment of the invention. Structure however may be modified and changed as regards this illustration, all within the true intent and scope of the invention as hereinafter defined and claimed.

FIG. 2 is a broken longitudinal sectional View on substantially the plane of line 2-2. of FIG. 1, showing the individual slide feeds at opposite ends of the machine.

FIG. 3 is a broken, enlarged, part sectional, plan view of the part assembling dies.

FIG. 4 is a cross sectional view on substantially the plane of line 4-4 of FIG. 3.

FIG. 5 is a broken cross sectional view of the assembly slides on substantially the plane of line 5-5 of FIG. 3.

FIG. 6 is a cross sectional detail on line 66 of FIG. 3, illustrating the kicker slide operating within the front slide.

FIG. 7 is a broken part sectional plan view illustrating the severing and assembling steps.

FIG. 8 is a broken and part sectional front elevation illustrating stock in course of formation, severing and assemblage.

FIG. 9 is a broken diagrammatic view on the plane of the line 99 in FIG. 7 showing the front slide advanced 3,094,767. Patented June 25, 1963 to hold the two parts together while the stitching punches are operating.

FIG. 10 is a broken sectional detail illustrating the first, piercing step of the stitching punches.

FIG. 11 is a similar view illustrating the second, riveting or upsetting step of the stitching punches.

FIG. 12 is a broken plan view of portions of the left hand end of the machine shown in FIG. 1, illustrating particularly the slide feed mechanism.

FIG. 13 is a broken transverse sectional view on substantially the plane of line 13-13 of FIG. 1, showing the cam and connections therefrom for effecting opening and closing of the gripper.

FIG. 14 is an enlarged perspective view of the parts made up and combined by the machine.

FIG. 1 is a general view of the machine, known as a Duplex Multi-Slide embodying front and rear, left and right hand shafts 15, 16, 17, 18 geared together about a rectangular machine tool bed 19 and carrying the cams and eccentrics for operating the dies and tools mounted on the bed.

A motor at the right hand end drives through belt connections 29 a counter shaft 21 connected by gears 22 with the right hand cam shaft 18 and the counter shaft carries a hand wheel 23 for turning over the machine in setting up the tools.

The feed mechanism at the left end of the machine is designated 24 and that at the right hand end is designated 2.5.

These feed mechanisms are shown as slide feeds consisting each of a feed block 26 mounted to slide on guide rods 27 and carrying a lever 28 pivoted at 29 so as to pinch the stock, 30 at the left and 3-1 at the right against an abutment wall 32, the gripper lever carrying the roller 33 engaged by a cam 34 on a cross slide 35, with the latter positioned from cams 36 on the front and back power shafts 15, 16.

These cams are shown as actuating rockers 37 connected by links 38 with plates 39 supported by swinging parallel links 40 and carrying at their inner edges rails 41 sliding between spaced rollers 42 on the underside of the cam carrying slides 35.

The parallel links 49 give the rail carrying plates straight in and out movement toward and away from the feed blocks, thus to effect desired opening and closing move ments of the stock grippers according to the cam shapes 34 and 36.

Reciprocation of the feed blocks 26 on the guide rods is effected in each instance from a crank pin 43 carried by crank disk 44 on a shaft 45 driven by gearing 46 from the end shafts 17, 118, these crank pins connected by links 47 with arms 48 on rock shafts 49, the latter carrying lever arms 50 connected by adjustable links 51 with pivot pins 52 on the feed blocks.

The rock shafts 49, which reciprocate the feed blocks, are shown journaled in brackets 53 adjustably mounted at 54 on opposite ends of the bed.

While the feed mechanisms at opposite ends of the bed are here shown as duplicates, it will be appreciated that they may be alike or be quite different, depending on the materials fed in at opposite ends of the machine, the extent of feed to be given such materials, the manner in which the products are to be combined or assembled and other such factors.

While illustrated for feeding flat strip stock the structure may be varied for handling other forms of strip, rod, wire and other such stock.

In the plan view, FIG. 1, the longitudinal center line of the machine is indicated at 55, with the wire line or feed for the left hand feed mechanism offset to one side and the feed line for the right hand feed mechanism laterally offset to the opposite side of the center line. While these two feed lines are shown offset equal distances to opposite sides of the center line, it will be understood that they may be offset unequal distances, depending upon the character of the Work and whether a stripping or forming post is used and other such factors.

Various kinds of shaping, forming, punching, drawing, cutting, drilling, tapping .and other such dies, tools and machine elements may be mounted on opposite ends.

'Fhese various kinds of machine tools have not been illustrated further than to indicate at 56 one set of tools at the left end of the machine operated from the front cam shaft for forming the stock fed in at the left end and one set of tools at 57 on the right hand end of the bed operated from the rear cam shaft 16 to form" stock fed in at the right end of the machine.

In the present illustration these forming tools are indicated as of the type shown in the Koch Patent 2,610,388 of September 16, 1952, with dies to form the two strips to the opposed channel shape shown at 58, 59, FIGS. 7, 8, 9.

These tools, as indicated in FIG. 8, carry or have associated with them dies 60 for notching the edges of the strips at 61 prior to the forming operation and cutters 62 for severing the formed blanks just prior to entry between the dies on the front and back slides 63, 64.

These two slides, as shown in FIGS. 3, 4 and 5, carry earn rolls 65, 66 in engagement with cams 67, 68 on the front and back cam shafts 15, 16.

The dies 69, 70 on the front and back slides are shaped to take the formed and cut blanks 71, 72 and the cams 67, 68 are shaped to approach these dies to grip and hold the blanks together in the opposed face to face relation shown in FIGS. 4, 7 and 9.

While the blanks are thus held together at the assembly point, stitching punches 73 on the rear tool 70 are advanced, as shown in FIG. 10, to pierce and turn back engaged edge portions of the clamped blanks and following this piercing step spanking tools 74 operating in the front slide are advanced to upset and rivet the pierced rand overturned portions of the blanks, as indicated at 75 in FIG. 11.

The stitching punches 73 are carried by a rear kicker slide 76 mounted on the back slide 64 and operated from a cam 77 on the rear cam shaft through rocker and link connections 78, 79, FIG. 4.

Similarly the front kicker slide 80 is actuated from cam 81 on the front cam shaft 15 through rocker and link connections 82, 83.

Strip material from separate sources of supply and possibly of the same or different character is thus advanced an opposite directions through notching and forming stages and cut off in blanks positioned in opposing face to face relation and gripped and held in this state while stitching and spanking punches fasten them together by integnal port-ions struck through from one side and headed over at the opposite side of the assembled blanks.

The completed units made up of the assembled independently formed parts may be discharged simply by separation of the front and back slides. For some parts it may be desirable to use a final formmg post or stripper and the parts may be formed and assembled on different levels or on the same level as in the present illustration.

It will be evident also that the two matching parts made at the opposite ends of the machine may differ in conformation and material and size or simply be dupli- Oates as in the present illustration.

Since all operations are automatic the machine may be operated at a high production rate.

The two lines of stock advancing in opposite directions approach in laterally offset overlapping relation thus to locate the shaped complemented parts in the face to face relation required for their proper connection. Guides may be provided so that the blanks cut at the ends of the strips will be properly directed by the continuous ends of such strips into coordinated relation between the holding and assembling dies.

The front and rear kicker earns 81 and 77 are shown as open, segmental cams allowing for independent movement of the stitching and spanking tools on the front and back tool carrying slides.
