HOERNLE BY Z W ATTORNEY Patented Jan. 6, 1948 UNIT!) STATES PATENT OFFICE MACHINE FOR MAKING TERMINALS AND THE LIKE My invention is directed to an improved method and apparatus for making terminals for condensers and other purposes.
One of the objects of my invention is to provide a method and apparatus whereby terminals having heads other than the conventional planar spiral may readily be formed.
Another object of my invention is to provide a machine of the type indicated which may be full automatic in operation, the starting material being taken from a reel or coil and discharged from the machine in finished condition.
Another object of my invention is to provide a machine capable of being operated at high speeds without danger of stoppage due to clogging or breakdown.
Other objects will appear from the description which follows:
In the accompanying drawing:
Fig. 1 is a plan View of one embodiment improved machine;
Fig. 2 is a section taken on the line 22 of Fig. 1;
Fig. 3 is a section taken on the line 3-3 of Fi 1;
Figs. 4, 5, 6 and '7 are fragmentary elevational views of the mechanism provided for bending the wire of the terminal in the initial stages of forming the terminal head;
Fig. 8 is an elevational fragmentary view illustrating the operation of the die mechanism which operates on the terminal head after the operation of the bending mechanism of Fig. 7;
Fig. 9 is a view similar to Fig. 8 illustrating the final die operation;
Fig. 10 is a section taken on the line ll}l of Fig. 8; and
Fig. 11 is a view in perspective of a finished terminal.
Referring to the drawings in detail: 2 designates the wire which is to be formed into terminals such as illustrated in Fig. 11, each terminal comprising a head 4 and shank 6. The head 4, it is to be noted, is of a shape other than the conventional planar spiral. I have illustrated a head that might be referred to as a closed, flattened loop, the plane of which is at right angles to the shank 6, and my improved machine is so constructed that the shank is disposed substantially centrally of this loop.
The wire may be fed through the machine by wire feeding mechanism such as disclosed in my prior Patent 2,293,506 of August 18, 1942, or any other suitable mechanism. This feature constiof my 21 Claims. (Cl. 14071) tutes no part of the present invention and hence will not be described in any detail.
The wire 2, which may be taken from any suitable reel or coil, is fed forward intermittently into or through bore 8 in a stationary bar It] fixed in casing 2. The bore of this bar lies directly in the path of the wire, as will be seen from Fig. 3.
The inner end of the bore 8 is enlarged to receive a mandrel 14, which is a stationary member also. The mandrel is provided with a longitudinal bore l6, aligned with bore 8.
Mounted on bearings i8 concentric with the mandrel l4, and adjacent the inner end of the mandrel, is a gear 20, carrying a rotary bending head 22.
The inner end of the mandrel l4 projects slightly beyond the face of the bending head 22 and is provided with a non-circular reduced portion 24 which, as will be seen from Fig. 4, is the shape of the head 4 to be formed, this reduced portion 24 cooperating with a bending or forming roller 26 rotatably carried on a cam-operated bell crank lever 28 pivoted in the face of the bending head 22, the free arm of this bell crank projecting beyond the periphery of the head 22 as seen in Figs. 4 to 7, inclusive. The lever 28 works against a spring 30 carried in the head 22, and its movement about its pivot under the action of this spring in a direction to swing the roller 26 away from the wire is limited by the rear wall 32 of the depression in the head 22 in which the lever is set.
It is to be appreciated that the function of the roller 26 is to bend the wire 2 into the shape shown, for example, in Figs. 5, 6 and 7 as will be brought out hereinafter.
It is to be understood that the wire 2 is fed forward intermittently as explained in my prior patent above referred to, and comes to rest with the wire projecting from the inner end of the bore 16 in the mandrel l4 beyond the reduced portion 24 of the mandrel, as shown in Fig. 1, and as shown in broken lines in Fig. 3.
In this position the wire is given its first bend, a right angle bend, by a bending arm 34 which is pivoted. at 36 and cooperates with a cam 38 on driven operating shaft 40 which moves the arm across the face of the bending head transversely of the projecting portion of the wire. It will be seen from the drawings that if the arm 34 is pivoted anticlockwise from the position shown in Fig. 1 to the position shown in Fig. 4, the projecting portion of the wire 2 will be bent downwardly to the position shown in Fig. 4.
As above pointed out, the mandrel I4 is staa lever pivotally mounted in the face of said head, and a roller carried thereby, and a cam for actuating said lever to bring the roller into engagement with the wire to bend the wire about said reduced portion of the mandrel as said bending head is rotated.
