Description

A METHOD AND APPARATUS FOR SECURING A FINISHING ELEMENT TO A WIRE ROPE DESCRIPTION OF THE INVENTION The present invention is directed to a stamping process and apparatus for producing efficient wire rope terminators. In particular, the present invention is directed to a method involving a stamping process and apparatus for use in the method for converting a cylindrical stamped sleeve by encircling a wire rope into a sleeve having a non-circular external transverse sectional shape. In a particular application, the method of this invention is useful in joining stamped plug type terminating elements to the end portion of a wire rope. Such stamped plug terminators are typically either an open stamped plug in which the terminator element has parallel integral rabe portions spaced apart or the stamped plug is a closed stamped plug in which the terminator element has a body portion with an aperture a through him. The wire rope terminator fits generally comprise cylindrical shaped sleeves that are used in a variety of wire rope terminators. Typically, the printed sleeves are externally and internally cylindrical and sized to receive a particular wire rope size therein. A sleeve typically used to form a rope sling eye. Wire, particularly eye-terminated Flames termination, is cylindrical with one end being tapered, such sleeves form the terminator by stamping, i.e., cold stamping. cuff to form a strong bond with the wire rope. Such patterns and methods for forming them are known in the prior art and described in the NATIONAL SWAGE CATALOG of The Crosby Group, Inc. In the above stamping information process, a round sleeve is placed at the end point and then placed inside the die. cylindrical that coactuates open. The shape of the cylindrical die represents the dimension of the finished pattern for a given size of wire rope identified as the "posterior embossed dimension". The prior art process requires that the coercion dice be partially closed at about one half of the distance from the initial contact of time between the sleeves and the dice. The die is then opened and the sleeve is rotated. This step is repeated upwardly three to four times until the dice are currently closed and clapped to create the upper stamped dimension to hold the operating load limits for a given wire rope size. As the size of the rope, wire increases even more the repeated rotation of the sleeve and multiple pressure is required. A step pattern has been taught in the prior art such as U.S. 2,151,032 British Patent 1,249,352 dated October 13, 1971; and PCT / GB94 / 02025 filed September 16, 1994. Such method and apparatus will create unappreciated "burr" of the material between the "area" surfaces of the dice if the dice are closed much more during the first and second stamping steps . The present invention is directed to a further improved apparatus and method of creating a correct post embossing dimension embossing for a given load limit, based on the size of the wire rope, in fewer steps than those required with given dimensions. cavity of conventional circular transverse section. The load limit in operation is defined as the maximum mass with force that the product is designed to support in general service when a pull is applied to the wire rope, plus a "design" factor. load capacity of theoretical reserve of computed product by dividing the last load of the catalog by the load limit in operation.This is generally expressed as a ratio, for example, A further object of the invention is to provide a process for creating a wire rope terminator wherein a circular or cylindrical sleeve is the die formed by a two-step (or multi-step) compression method in an external form not circular that can be multi-sided, polygonal such as a hexagonal shape. To practice the invention, the circular sleeve is placed inside coercion dice that have splicing areas. At least one of the dice coact by possessing a receptacle area to allow the sleeve to flow into the compressed receptacle area. This prevents the sleeve material (burr) from flowing in the area between the splicing areas. In the preferred embodiment, the dice are closed in a first time to form the sleeve in an almost hexagonal shape, the almost hexagonal sleeve will approximate the shape to a hexagon except for the side or sides that are exposed to a receptacle area in the die. The coercion dice are then opened and the sleeve is rotated. The coercion dice are then closed again, forming the sleeve in an almost hexagonal final shape. During the training process each time the dice are closed, the areas of the duress dice are spliced. This fact greatly diminishes operator attention associated with previous stamping processes. After a double step using the method described herein, a stamping properly formed at the end point of the wire rope with the subsequent embossing dimensions to produce own operation plus the load limits of design factor for the size of the wire rope that is formed. Specifically, the invention is directed to hexagonal or polygonal die cavities, wherein at least one, preferably two, of the opposite face sides include a receptacle area for embossed material to flow in a first complete closure of the dice, that is, the splicing of die area surfaces. One method includes a second stage of stamping provision less than 180 ° followed by a second complete closing of the dice. • The invention being preferably directed to the use of such a method and apparatus in one embodiment, to form a Flames eye wire rope sling. A third step may be required where there is excess clearance in the guide supports of the hydraulic stamping machine. One aspect of the invention is a method of securing a stamping plug termination element to an end portion of a wire rope. Stamping plug terminations can occur in several ways but usually in two main ways. The first commonly called an open stamping plug. This type of devices has a body portion with two parallel rabe portions that extend integrally. The rabe portions typically have openings 1 aligned at the outer end so that a bolt or other type of key members can be inserted through the openings by which the open stamping plug can be secured to some other pieces of equipment. The open stamping plug has an elongated integral tubular member, the end portion of a wire rope being received in the tubular portion. The open stamping plug is secured to the end portion of the wire rope by cold stamping or deformation of the integral tubular portion around the end portion of the wire rope. This invention is concerned with an improved form of deformation of the tubular portion of an open stamping plug to secure it to the end portion of a wire rope. Another type of stamping plug is called a closed stamping plug. It is similar to the open stamping plug except that the body portion of the closed stamping plug has an opening through it, that is, it has no raberas portions that extend integral. A closed stamping plug has a tubular portion to be integrally released which receives the end portion of a wire rope. The tubular portion is deformable by cold flow to form around and attached to the end portion of the wire.

Referring now to Figure 1, the steel sleeve as used in this invention and as described in the prior art includes a cylindrical body which is generally designated by the numeral 10 and externally includes a cylindrical body portion 12 of a OD determined and end portion 14 tapered. Internally, the sleeve is made of a given cylindrical portion 16 of ID ending at 17 with an internally tapered end 18 and a circular opening 20 which is a size longer than the size of the wire rope. For example, using a 25-26 cm (1") wire rope, the openings 20 should be designated approximately longer than 2.54 cm (1") while the internal diameter of the cylindrical portion 16 is roughly designated to receive the cluster. of all the wires comprising the tail ends 32A, 32B and the running line 30. Such sleeves have sufficient ductility to flow plastically cooled in the terminators. One of the sleeves is sold by The Crosby Group. Inc. under the brand name "COLD TUFF" ©. The concepts of this invention are particularly applicable to the use of a standard round steel sleeve in the construction of a Flames eye splice at the end of a wire rope but is not limited thereto. Such eye splices and slings are common and useful in conjunction with other lifting and lifting equipment. The process according to the invention is shown in Figures 2 to 8. The so-called Flames-type wire rope sling eye is a mechanical splicing of the braids of the wire rope. The run portion 30 of a wire rope includes a tail end, generally designated by the number 32. As is well known, the wire rope is constructed of wire braids placed together. A braided wire rope is typically made of six braided wires and a core. Each braid can be of a number of individual wires. The wire braids are helically placed around the core either to the right or to the left with the resulting string designated as a right wiring or a left wiring. In the Flames eye joint, the body of the rope is open or unfolded in two parts, one has three braids and the other has the rest of the three braids and the cap. The rope is uncoupled far enough behind to allow the loop or eye to be formed by lacing one part in one direction and the other part in the other direction.

The core of some wire ropes is made of some form of wire or fiber that adds extra strength to the rope. The wire rope is classified as, for example, as "6 x 19"; the first number being the number of braids in the string and the last number the number of wires in a braid. If there is a wire core, the wire is labeled I RC (Independent Wire Rope Core). The total metal section area of a wire rope is important in the design of the coercion dice and the process of this invention which will be detailed hereafter. The percentage of unfilled voids is known as the percentage of air cavity. As shown in Figures 2 and 3, the braids of the tail end 32 are separated into two parts, generally designated 32A and 32B with a core 33. The sleeve 10 is placed in the run line 30 in the direction as shown in FIG. sample. The two parts of the tail end are then repositioned in the run line 30 to form the o o. The two ends 32A and 32B are then extended to a point 36, which may be previously marked at 38 which converts the area of the terminator. The next step is to slide the sleeve 10 forward of the terminating point 36 which will circulate the re-arranged wire rope forming the spliced Flames eye generally designated by the number 40 as shown in Figure 4. Enzyme of this point, the process is that which is being known in the art, and ordinarily, the sleeve must be placed within a round coaction die in a hydraulic pattern to form the pattern in a plurality of turns and steps to the subsequent embossing dimension adequate has been reached and calibrated. This invention, however, is directed to form an almost hexagonal pattern of the round sleeve 10 by the use of coercion dice by a two-step method as shown in Figures 5, 6, 6A and '7. The coercion dies 50 and 52 are used in a typical hydraulic stamping machine capable of applying many tons of pressure with a lower die 52 and generally being fixed inside the machine, while the die 50 is movable vertically or vice versa as shown by the arrows. The die of this invention comprises an almost hexagonal opening 53. When the upper area 56 and the lower area 58 splice, the cross-sectional area of the opening 56 is critical to the successful formation of a correct, almost hexagonal shaped rear terminator. The upper and lower die, each containing, in this embodiment, three sides that form the almost hexagonal transverse section but where the upper surface 54 and the lower surface 55 of the opening are not flat but instead are curved outwardly in a "dome" shape to create a receptacle 51 for the embossing material during the first step as shown in Figure 6. The assembled sleeve as shown in Figure 4 in the terminator area is placed inside, of the die 52 lower, and by means of a hydraulic pressure, the die or dice are forced together to apply pressure against the sleeve. Some light oil lubricant is applied to the sleeve. As shown in Figure 5, the die begins to close in the cylindrical sleeve 10 to form a preformed polygonal, preferably an almost hexagonal pattern having the sides A, B, C, D, E and F, shown in Figures 6. and 6A. Other polygonal shapes even numbered greater than 6 encompassed by the invention. The purpose of the "dome" formed of surface 54 and 55 of receptacle for sides A and D is to form an area 51 in which the material of the sleeve can flow. As such, the dice will not form excess "burr" or pinch material between surface 56 and 58 before closing. As shown, the hydraulic pressure is applied to the dies to the spliced areas 56 and 58 as shown in Figure 6. After closing on the sleeve, the die is opened by rebelling a pattern formed in an almost hexagonal shape. The next step in the process is to rotate the preformed pattern on one side or, in this case, 60 ° to the position as shown in Figure 6A. Close the dice, at this point, the ductile metal sleeve currently compresses the wire rope and the core and flows plastically into the valleys and spaces between the braided components as shown in Figure 7. The dice mouths are open and The finished finished Flames eye is removed creating, in the finishing area, the final almost hexagonal stamped shape generally designated by the number 10A. Figure 10 illustrates a cross-sectional view of the dies 50 or 52. An important aspect of the invention is the design of a cross-sectional area of the designated duress cavity, as shown in Figure 9, as AD , including the "W" width and the space between the "B" planes. The design of a die cavity for a Flames eye splice terminator can be expressed by the following arithmetic steps: First, the metal sleeve cross-sectional area is determined: As = (OD2-ID2) -p 4 The area of the metal rope is calculated: Ar = (DR2-Af) Where: DR = Rope diameter Af = metal area factor of wire rope usury manual as published by The Wire Rope Technical Board. The hexagonal die area does not include the dome-shaped receptacle areas 53 [Are there 2 areas here? 53 is an almost hexagonal opening] is then calculated: .2 lD TAN 30 ° (6) (-) Where B = to the transverse planes of posterior embossing dimension. It is known that the stamping process will curl and bring together the individual wire braids inside the sleeve. A balance should be found between a tight pattern and cut the string braids off. wire that reduce efficiency. Since, there is no total compression, voids not filled in cross section within the pattern are known as the air cavity. The percent of air cavity is found: AD - (2A + AS)% Air Cavity = - - - "100 which must be equal to or less than 40%. The percentage of width of the die cavity to the OD sleeve is contracted: and is equal to or greater than 90% of the OD sleeve. An example of a typical height "h" of the dome-shaped area is a height of 1/16"in the die area designated to produce a 3/4" hexagonal pattern. Although the invention is described relative to the eye form Flames of terminator, the concepts are applied to other terminator forms. Examples include creating hexagonal stamping terminators that are known as cylindrical stamping sockets as described in the NATIONAL SWAGE catalog of The Crosby Group, Inc. Also, even the invention creates a hexagonal stamping of an oval sleeve that is known as a return eye shape (ie wire rope on wire rope) of terminator as described in the NATIONAL SWAGE catalog before bending. The invention is further adapted for wire rope embossing buttons as shown in the aforementioned catalog. While the description of the invention directed to Figures 1-10 has been primarily concerned with a way of practicing the invention to the form that is known in the trademark as a "Flames eye splice", the invention does not mean to be limited to this. specific type of wire rope terminator. Rather than an eye splice or another type of splice in which an integral loop is formed at the end of a wire rope, terminating devices are frequently employed. Two common types of terminating devices are called the "open splice plug" and the "closed splice plug". Figures 11-17 show an open stamped plug of the type commonly secured to the end of a wire rope while Figures 19-24 show a closed stamping plug. The invention herein is particularly adaptable for attaching these types of stamping plug of terminating elements to a wire rope. As shown in Figures 11-14 a wire rope 60 and an open stamp plug generally indicated by the number 62. The open stamp plug 62 has a body portion 64 having portions 66 and 68 integrally extended therefrom. Raberas spaced apart and parallel. Each of the portions 66 and 68 rabbits has an opening 70 therein, the aligned openings receiving a pin 72, the pin having an elongated head 74 at one end and a small diameter transferase opening at the other end that typically receives a key 76 of key. Extending integrally from the body portion 64 is an elongated tubular portion 78 having an opening 80 therein that receives the end portion of the wire rope 60. The tubular portion 78 typically has a cylindrical outer surface 82. In the embodiment illustrated in Figures 11 and 12 the outer surface has a reduced diameter end portion 84 that is provided in accordance with an invention covered in US Patent No. 5,152,630 to provide a way to quickly determine whether or not the plug 62 stamping has been secured to rope 60 wire cable. The invention is covered by US Patent No. 5,154,630 given in a very generalized summary, a system in which the reduced end portion 84 substantially disappears when the curling action is applied to the tubular portion of the outer cylindrical surface 82 to join the plug 62 for wire stamping 60, so it provides a visual indication that is known by the trademark, "QUIC-CHECK", the trademark being owned by The Crosby Group, Inc. The provision of the reduced diameter portion 84 is not a part of this invention. The invention described herein is experienced whether or not the outer cylindrical surface 82 of the stamped plug tubular portion 78 has reduced outer diameter portion 84 or does not have such a reduced diameter portion. In the present practice, the method of securing the open stamping plug 62 to the wire rope 60 is assembled in the manner illustrated in FIGS. 11-14 and then holds the integral tubular portion 78 to a die having semicircular recesses in it. same for printing the tubular portion 78 to reduce the internal diameter of the opening 80 causing it to conform, at least in part, to the external configuration of the wire rope 60. In the final annex, using the present state of the art, before this invention, the open and complete open stamping plug 62 maintains an integral tubular portion 78 that is essentially circular in the form of an external cross section. The method of this invention of attaching the open stamping plug 62 to the wire rope 60 is illustrated in Figures 24-29 whose reference will now be given. In the new concept described herein, the wire rope 60 is attached to the open stamping plug 62 by cold flow or stamped the integral tubular plug portion 78 stamped using opposite die portions 50 and 52 having non-circular configuration (see Figures 25-30). The dice having this configuration have been previously described with reference to Figures 5, 6, 6A, 9 and 10. The dice of this invention provide an opening, when the dice are closed as in Figure 26, which is non-circular. The specific configuration of the opening in the closed dies of Figure 26 is almost hexagonal. The die of this invention comprises an almost hexagonal opening 53. When the upper area 56 and the lower area 58 splice, the transverse sectional area of the openings 53 is critical to the successful formation of a correct, almost hexagonal rear stamped configuration of the tubular open plug portion 78. The lower and upper die each contain, in the illustrated embodiment, three sides that form the almost hexagonal transverse section but where the upper surface 54 and the lower surface 55 of the opening are not flat but instead are outwardly curved in a "dome" shape to create a receptacle 51 for the embossed material during the first step as shown in Figure 26. As shown in Figure 26, the die 50 closes on the cylindrical tubular portion 78 to form a polygonal preformed (almost hexagonal in the illustrated mode). Other polygonal shapes are inclusive of the invention. The purpose of the dome-shaped receptacle surfaces 64 and 55 is to form an area 51 in which the material of the sleeve can flow so that the dies will not form excess "burr" or pinch material between areas 56 and 58 before closing. After closing in the tubular portion 78 the die is opened revealing a pattern formed in the almost hexagonal shape. The next step in the process is to rotate the preformed tubular portion 78 as shown in Figure 28 in the position as shown in Figure 29. Close the die a second time the cold flow of the ductile metal compresses the wire rope 60 and flows plastically into the valleys and spaces between the braided components of the wire rope as shown in Figure 30. The die openings are open and the finished patterned tubular portion 78 of the stamped plug 62 is forged removed, the tubular portion 78 which has an almost hexagonal stamped shape as seen in Figure 30. In the broad concept of practicing the invention, the configuration of the aperture formed when the dice 50 and 52 are closed to each other which is, when areas 56 and 58 are in contact, it is not circular. By "non-circular" is meant a predetermined geometrical cross-sectional configuration that can be, as in the illustrated, hexagonal mode, and can obviously be octagonal or any other symmetric external configuration or the dice can form an aperture of non-circular configurations in a preselected way. The essence of the invention is that the shape of the dies forming the opening is non-circular and arranged to produce a preselected external configuration in the terminator element such as an open or closed embossing plug. As shown in Figure 28, and as previously stated, the integral tubular portion 78 of terminator member is rotated to a preselected number of degrees that is less than 180 °. In the illustrated arrangement where the final desired external configuration is hexagonal, the integral tubular portion is rotated 60 °. For other recently desired external transverse section shapes of the tubular portion of terminator element the amount of rotation will be more or less but in all cases less than 180 °. After the tubular element has been rotated as illustrated in Figure 28 the dice are closed again as shown in Figure 29 to further shape the outer surface of the integral tubular portion of the terminator element to the desired configuration. As previously described, in the preferred practice of the invention the opening through the data is configured to allow the receptacle 51 as shown in Figure 29 to accommodate the excess of coined flow as the tubular portion is formed so that the dice can always close completely with areas 56 and 58 in contact with one another. Figures 18 and 30 show the complete stamping operation by which the open stamping plug 62 of Figures 11-17 has been secured to the wire rope 60. The finished appearance after the open stamping plug 62 has been attached to the wire rope 60 is illustrated in Figures 15-18.

Figures 11-17 are illustrative of the application of the invention to an open embossing plug. Figures 19-24 show the invention as applied to a closed embossing plug. The application of the invention for any of the open or closed embossing plugs is substantially identical, the embossing plugs being different only in the extreme configuration by which another element, such as another length of the line or piece of equipment is attached to the end of a cable. In Figures 19-24, the number 86 generally indicates a closed embossing plug that includes a body portion 84, integral with the body portion a toroid portion 90 having an opening 92 therein. Fully extending from the body portion 88 in the opposite direction of the toroid portion 90 is a tubular portion 94 having an opening 96 therein, the opening receiving the wire rope 60. As fabricated the tubular portion 94 typically has a cylindrical outer surface 98. In the illustrated configuration of Figures 19 and 20 the outer cylindrical surface 98 has a reduced diameter end portion 100 which, as explained with reference to the application of the open wedge plug of the invention, is for the purpose of providing a visual identification of whether or not the tubular cylindrical portion of the stamping plug has been treated, by stamping, attaching the stamped plug to the final portion of the wire rope 60. As previously stated, the use of the reduced diameter portion 100 of the tubular portion 94 is optional and is not part of this invention. When the tubular portion 94 is subjected to the stamping operation the portion 100 of reduced diameter essentially disappears as well as provides a visual indication that the stamped plug has been secured to the end of a length of the wire rope. The tubular swaging plug portion 94 is subject to stamping operation as illustrated in Figures 25-30 as previously described with reference to the open stamping plug of Figures 11-16. The result of the stamping operation is to change the tubular portion 94 of the stamping plug to have an external non-circular configuration, the non-circular configuration being of a predetermined cross-sectional shape is joined by a stamping operation as illustrated in the Figures 25 and 30 in which the tubular portion 94 is rotated at least once during the stamping operation. In the arrangements illustrated by the open embossing plug (Figures 11-18) and the closed embossing plug (Figures 19-24) the external pre-selected configuration that is attached by the embossing operation is the hexagonal surface. This is in accordance with the method of forming a tubular member illustrated in Figures 5, 6, 6a, 7 and 9 and Figures 24-29. As previously stated, the predetermined external configuration may be different from the hexagonal and may, for example, be octagonal or may be other preferred non-circular configurations.
