8 Claims. (Cl. 140-147) This invention relates to wire-straighteners, and more particularly to apparatus for straightening a multitude of wires simultaneously.
In manufacturing operations wherein a plurality of wires are formed into objects simultaneously by machines operable intermittently, such as, for example, a press, it sometimes is essential that the wires be perfectly straight as they are fed to such a machine, and it is also essential that the wires be fed uniformly to the machine. Where individual wire straightening machines are used, it has been very diflicult to synchronize the feed of each machine. Also, in the past there has been no satisfactory machine for straightening a plurality of wires uniformly.
An object of the invention is to provide new and improved wire-straighteners.
Another object of the invention is to provide new and improved apparatus for straightening a multitude of wires simultaneously.
Another object of the invention is to provide apparatus for advancing a plurality of wires at a uniform speed and straightening the wires as they are so advanced.
A further object of the invention is to provide a compact, easily maintained wire-straightening machine which may be easily adapted to several sizes and types of wires.
An apparatus illustrating certain features of the invention may include a cartridge type wire-straightening element designed to be replaceably mounted in a rotatable holder, and means may be provided for feeding a plurality of wires to the wire-straightening elements.
A wire straightener illustrating the invention more specifically may include a grooved roll for advancing in cooperation with presser rolls, a plurality of wires to a plurality of rotatable wire-straightening heads. Each of the heads includes a pair of tubes mounted in tandem, which are rotated in opposite directions and cartridges designed to be inserted and removed from an end of one of the tubes. Each cartridge is separable into two halves, each rotatable with respect to the other and each half of the cartridge has a slot therein for receiving wire-forming dies.
A complete understanding of the invention may be had from the following detailed description of an apparatus forming a specific embodiment thereof, when read in conjunction with the appended drawings, in which Fig. l is a fragmentary, top plan view of an apparatus forming one embodiment of the invention with portions thereof shown in section;
Fig. 2 is a vertical section taken along the line 2-2 of Fig. 1;
Fig. 3 is a vertical section taken along the line 3-3 of Fig. 2;
Fig. 4 is an enlarged vertical section taken along the line 4-4 of Fig. 1;
Fig. 5 is an enlarged fragmentary section of a portion of the apparatus shown in Fig. 4;
Fig. 6 is an enlarged fragmentary section taken along the line 66 of Fig. 5, and
Fig. 7 is an enlarged fragmentary section of a portion of the apparatus shown in Fig. 3.
Referring now indetail to the drawings, there is shown therein a machine for straightening wires 11 and for pushing the wires therethrough at a rate of speed uniform for all the wires. The wires are guided by tubes 12 (Figs. 1 and 2) mounted in a housing 13 and travel from the tubes 12 to grooves 15 formed in an upper roll 17 also having aligning grooves 16 therein. The wires are pressed into the grooves 15 (Figs. '2 and 3) and into grooves 27 in rolls 22 splined to a shaft 23 by pins 24 fitting in sockets in the rolls 22 and projecting through wide slots 25 formed in the shaft 23. Bearings 26 mount the shaft 23 rotatably. The rolls 22 have tapered ribs 21 and are mounted rockably on tapered bushings 31 fitting loosely on the shaft 23. Bearings 32 supported by arms 34 of bell crank levers 35 having cam follower rolls 36 mount the bushings 31. The roll 17 is driven in a wire-advancing direction by a V-belt drive 41 and drives the rolls 22 in the same direction through gears '42 and 43 connecting the roll 17 to the shaft 23.
During the normal operation of the machine, the bell crank levers 35 are urged in an individually clockwise direction, as viewed in Fig. 2, by compression springs 51 mounted on rods 52 supported by guides 53 mounted on the housing 13. The compression springs 51 press against a lug 61 fastened rigidly to the arms 54 and press the rolls 22 tightly against the wires 11 in the grooves '16, each roll 22 pressing against two of the wires and rocking on the tapered bushings to equalize the pressure on the wires. The ribs 21 hold the rolls 22 against lon gitudinal movement relative to the roll 17. A manually operable cam 62 is designed to force the bell crank levers 35 in a counter-clockwise direction to move the rolls 22 out of the path of the wires 11 when it is desired to string up the machine. The rolls 17 and 22 advance the wires 11 to the right, as viewed in Fig. 2, into guide tubes 64 and 65, the guide tubes 64 diverging upwardly to wirestraightening units 66 and the guide tubes 65 travelling downwardly to wire-straightening units 67.
The wire-straightening units 66 are identical with one another and with the wire-straightening units 67, the
As each wire 11 travels through one of the wirestraightening units 66 and 67, the cam plates 97 and 98 form a predeterminedly tortuous path therebetween and are rapidly rotated in one direction around the wire so that they spin the wire to substantially straighten the wires. which are revolved in one direction, to the cam plates 99 and 100, which are revolved in the opposite direction at a substantially higher rate of speed than that at which the cam plates 97 and 98 are revolved and form a substantially less tortuous path for the wire than that of the cam plates 97 and 98. The cam plates 99 and 100 spin the wire in the opposite direction to complete the straightening thereof. The wires come out of the wirestraightening units 66 and 67 completely straight and at the same rate of speed. The configuration of the path formed by the plates 97 and 98 is more greatly tortuous than that formed by the cam plates 99 and 100 so that the wire is initially straightened more roughly and then is very precisely straightened as it travels between the plates 99 and 100.
Each of the cartridges 82 may be pulled to the right, as viewed in Fig. 4, to pull the cartridge completely out of the sleeves 71 and 75 so that the cam plates 97, 98, 99 and 100 may be inspected and replaced if worn and also for purposes of stringing up the cartridge with the wire whenever necessary. The bushings 104 and 107 and the guide plates 105 and 106 may be replaced when desired to adapt the cartridges to wires of different sizes or different types and the cam plates, of course, also may be replaced. The ends of the cam plates 98 and 99 adjacent to one another are designed to fit under the joint 85 to lock these ends of the plates 98 and 99 in the holders 83 and 84, and the leaf springs 91 resiliently hold the .outer ends of the cam plates 98 and 99 in the cartridge, as well as keying the holders 83 and 84 to the tubes 71 and 75 and holding the holders against longitudinal move ment relative to the tubes.
The above described apparatus is simple and compact in construction, and advances wires therethrough at the same rate of speed so that uniform straightening treatment is applied to each of the wires. Thus, this appajratus may be easily used in tandem with another apparatus requiring uniform feed of the wires. The apparatus 1s easily strung up, is easily adapted to Wires of different sizes and types, and the maintenance thereof is very simple.
It is to be understod that the above-described arrangements are simply illustrative of the application of the principles of this invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
Each wire travels from the cam plates 97 and 98, g 7
