Abstract
An end of a wire rope is received in a straight sleeve. and the sleeve is pressed between two die parts, defining a die of hexagonal cross-sectional shape, onto the rope. The sleeve is not bent in its longitudinal direction. The terminal may have two axially aligned sockets each to receive a rope end; or the sleeve may have a clevis. The press may be hand powered.
Description
SWAGING METHOD
The invention relates to a swaging method and in particular to a method of swaging the end of a wire rope or cable to a terminal.
In particular the invention relates to a method which is easy to perform and reliable using relatively simple and cheap equipment.
It is known to apply a terminal in the form of a fitting, e.g. a yacht fitting, having an integral sleeve to the end portion of a wire rope or to splice two lengths of such rope together.
Usually this work is done by skilled personnel using a high powered press which is expensive. In addition, while the sleeve is made with parallel sides, as a result of the swaging it tends to assume a curvature after swaging, which is unacceptable It is an object of this invention to provide such a method which can be performed on a relatively cheap press by even unskilled personnel.
In one aspect the invention provides a method of applying a terminal to a wire rope or cable, the method comprising receiving an end portion of the rope or cable in a substantially straight elongate sleeve portion, placing the assembly so formed in a press having to die parts which together define a die of generally hexagonal cross-sectional shape, moving one die part to the other to swage the sleeve portion and rope together without substantially bending the sleeve portion in a longitudinal direction.
As a result of the shape of the dies, the longitudinal parallel nature of the sleeve is not substantially changed. Because the dies are of hexagonal shape, little flash is formed which avoids the release of bits of metal which are included in the pressing operation and which can damage the sleeve portions or the surfaces of the die parts.
The die parts may have the same length as the sleeve portion so that one pressing will carry ot the swaging, or it may be shorter so that the total length is swaged in a series of longitudinal bites.
The press may be provided with an oil pump to be manually operated, e.g. by a hand lever or it may include a low power motor.
The terminal may comprise a splice having two axially aligned sleeve portions each to receive an end portion of a wire rope or cable, or a sleeve having an end portion such as a yacht fitting, e.g. a clevis.
Another advantage of the invention is that because of the efficiency of the swaging the total length of the terminal may be reduced.
The sleeve may be formed of steel, aluminium, copper or the like.
In order that the invention may be well understood it will now be described by way of illustration only with reference to the accompanying diagrammatic drawings in which:
Figure 1 is an elevation of a wire and a clevis yacht
fitting before swaging and partly in section;
Figure 2 is an elevation of the assembly of Figure 1 after
swaging, but at right angles;
Figure 3 is a transverse view of one die part showing the
other in ghost outline, and
Figure 4 is a side view of the die part of Figure 4.
The yacht fitting comprises a sleeve portion 1 made of steel having a T-shaped clevis head 2 to receive a bolt, not shown.
The sleeve has a parallel sided wall portion 3, e.g. of circular section, defining a bore 4 to receive an end portion of a length of wire rope W. In use an end portion of the rope is received in the bore 4 and the assembly so formed inserted in a press, not shown, having a die assembly formed of two co-operating die parts, one of which, 10, is shown in Figures 3 and 4. The die part 10 has three integral surfaces 11 joined to one another at an angle of.about 600. The assembly of Figure 2 is received in the die and pressure applied to urge the die parts together to swage the sleeve on to the assembly, so joining the wire W and the sleeve 1 together. The pressure may be man-generated using pressurised oil or a small motor. The die part 10 is short relative to the length of the sleeve (Figure 4) so that swaging is done in a succession of longitudinal bites. The outer sides 12 of the die parts are radiused as shown in Figure 4. As a result of the swaging a connection of satisfactory tensile strength has been made. The parallel nature of the side wail 3 has been maintained, instead of the unsightly curvature often experienced with larger scale presses. Little or no flash is formed, so that the dies have a long life.
An advantage of the use of the press is that because it is cheap, it can be readily available and used by relatively unskilled labour.
The invention is not limited to the embodiment shown. The fitting need not be a clevis but can be ...........?
Claims (5)
- CLAIMS 1. A method of applying a terminal to a wire rope or cable, the method comprising receiving an end portion of the rope or cable in a substantially straight elongate sleeve portion, placing the assembly so formed in a press having two die parts which together define a die of generally hexagonal cross-sectional shape, and moving one die part towards the other to swage the sleeve portion and rope together without substantially bending the sleeve portion in a longitudinal direction.
- 2. A method according to Claim 1, wherein the die parts have the same length as the sleeve portion so that one pressing will carry out the swaging.
- 3. A method according to Claim 1 or 2, wherein the press is manually operated, e.g. by a hand lever or by a low power motor.
- 4. A method according to any preceding Claim, wherein the terminal has two axially aligned sleeve portions each to receive an end portion of a wire rope or cable, or a sleeve having one end portion such as a yacht fitting, e.g. a clevis.
- 5. A method according to any preceding Claim, wherein the terminal has a through passageway to receive the rope or cable.
