"Improvements in or relating to Swaying Apparatus"
DESCRIPTION
This invention is concerned with apparatus by which a loose sleeve-like fitting may be swayed onto a core.
Swaying apparatus has been proposed which provides a plurality of forming dies surrounding the article to be formed and where the forming action results from impact of the dies on the article. The total energy required in moving the dies so that they hit the article with the force necessary to deform it is con-siderable and die wear in such an apparatus is high. Further, it may be difficult to adapt such apparatus for-automatic feed of the articles where they are, for example, to be joined onto other articles, such as sleeve-like fittings being joined onto cores.
In an effort to reduce the forces acting on the dies, it has been proposed to taper the die surfaces that engage the article so that the die engages the article gradually. Even so, energy required to move the dies is considerable. An object of the invention is to provide a swaying apparatus by which swaying can be effected by the economical use of force.
According to the present invention there is provided swaying apparatus including a plurality of pivoted members which can swing simultaneously through a swaying station about fixed axes disposed around the swaying station, in the swaying station the separation between the edges of the members remote from the axes is a minimum and when the separation is a minimum each such C edge is touched by a circle of which the axis is transverse to the axes about which the pivoted members swing.

By way of example, an embodiment of the invention will now be described with reference to the accompanying drawings in which:
. Figure 1 is a partial sectional exploded view showing a sleeve-like fitting and a core prior to their being swayed together;
Figure 2 is a view partly in section and partly in side vie with some parts removed, and shows the apparatus and the fitting prior to swaying;

: Figure 6 is a view similar to that of figure 2 illustrating a modification of the swaying apparatus shown in Figure 2; and Figure 7 is a view similar to that of Figure 2 illustrating a Further modification of the swaying apparatus shown in Figure 2.
Figure 1 shows a sleeve-like fitting 1 which is to be swayed onto a core 2.
The fitting may serve as the termination member of a conduit and the core is in the form of a flat wire metal conduit so that this conduit, together with a conduit to which the termination member may be connected, I
constitutes, after sieging conduit assembly. The fitting has a hexagonal configuration and the swaying operation is such that each race 3 is swayed, or crimped, inwardly at point 4 so that the fitting is mixed tightly to the core 2.
The apparatus by which the swaying is effected comprises a plurality of staging tools 21 in the Norm ox blades, each mounted for rotation about a pin 22 carried in a roller block 23 which in turn is mounted ox fixed frame member 24.
The swaying tools are arranged in a circle in three pairs with the tools of each pair opposed to each other. Each tool 21 has a forming race 25 which in cross section and side view have the profiles that will produce the desired configurations of the fitting after swaying. In the embodiments shown in the drawings, the profile of the forming face forms, in the length-wise direction of the fitting, an arc of a circle-; centered on the axis about which the tool swings and, transversely to this, as shown in Figure 5, the cross-section of' the worming face forms part ox a trapezoid.
The swaying tools together define a swaying station 26 having an entry side to the right ox a plane containing the fixed axes of the pins 22 as shown in figure 2 and an exit side to the let ox the plane. The tools 21 may swing prom the positions in which they are shown in Figure 2 to that in which they are shown in Figure 3. During that movement, they pass through the swaying station in which the separation between them is minimum and then the forming races, or edges, 25 :

of each of the tools 21 touch a circle of which the arm is transverse to the axis about which the tools swing.
A pusher means 28 comprising a piston (not shown) slid able in hydraulic cylinder 29 and connected by rod 30 to a plate 31. Plate 31 has an extension 32 thereon, the end of the extension 32 forming a cavity member 33 that serves as a socket to receive an end of the fitting 1. Movement of the piston rod 30 in the direction of the straight arrows drives the cavity member 33 to the left to force the fitting through the swaying station and, as will now be described, simultaneously operates the swaying tools 21.
Between each swaying tool 21 and plate 31 there is a pusher finger 40 to comprise a positive drive corn-scion between the plate 31 and the tool. Each finger 40 pivotal rests at its end 41 in the plate 31. As the plate 31 moves, the fingers 40 will move the tools through the zone in which swaying is effected, the pivot-in of the fingers permitting them to tilt as appropriate during this movement.
A compression spring 42 is provided for each finger 41 to ensure that the end of the finger 41 remains in contact with the plate 31.
Each tool 21 is connected to the plate 30 by a return spring 45 and urges each tool towards the position in which it is shown in Figure 2 so that it will return to that position after a swaying operation.

In using the swaying apparatus that has been described, a conduit 2 having a fitting loosely embracing the end is moved to the right, as shown in the drawings through the swaying station 26 until the fitting 1 seats within cavity member 33... At this juncture the hydraulic. cylinder 29 is pressurized to move the plate 31 and the other components that are connected to it to the left, in the direction ox the straight arrows. Such movement causes the fitting to move to the let and the movement of the fingers 40 rotates the tools 21 so thaw the forming races 25 swing through the swaying station 26. The faces 25 initially contact the fitting 1 at the entry side ox thy swaying station, but continued movement of the fitting and swaying tools 21 results in a rolling action of the forming faces 25 on the fitting 1 with result .: -that the faces 3 of the fitting buckle in to swag, or crimp, the fitting 1 onto the core 2. Continued movement of the cylinder 19 pushes the witting beyond the swaying station to the position shown in Figure 3 at which point the-fitting is removed from the cavity member 33. The hydraulic cylinder, and the parts that move with it, return to their starting position and return springs 45 rotate the swag tools back to their starting position where the suckle may then be repeated.

DESCRIPTION
This invention is concerned with apparatus by which a loose sleeve-like fitting may be swayed onto a core.
Swaying apparatus has been proposed which provides a plurality of forming dies surrounding the article to be formed and where the forming action results from impact of the dies on the article. The total energy required in moving the dies so that they hit the article with the force necessary to deform it is con-siderable and die wear in such an apparatus is high. Further, it may be difficult to adapt such apparatus for-automatic feed of the articles where they are, for example, to be joined onto other articles, such as sleeve-like fittings being joined onto cores.
In an effort to reduce the forces acting on the dies, it has been proposed to taper the die surfaces that engage the article so that the die engages the article gradually. Even so, energy required to move the dies is considerable. An object of the invention is to provide a swaying apparatus by which swaying can be effected by the economical use of force.
According to the present invention there is provided swaying apparatus including a plurality of pivoted members which can swing simultaneously through a swaying station about fixed axes disposed around the swaying station, in the swaying station the separation between the edges of the members remote from the axes is a minimum and when the separation is a minimum each such C edge is touched by a circle of which the axis is transverse to the axes about which the pivoted members swing.

By way of example, an embodiment of the invention will now be described with reference to the accompanying drawings in which:
. Figure 1 is a partial sectional exploded view showing a sleeve-like fitting and a core prior to their being swayed together;
Figure 2 is a view partly in section and partly in side vie with some parts removed, and shows the apparatus and the fitting prior to swaying;
Figure 3 is a view similar to that of Figure 1 showing the fitting and the apparatus after swaying;
Figure 4 is an enlarged cross-section of the flit-in of figure 1 swayed onto the core;
Figure 5 is an end view of the swaying apparatus seen from the left-hand side of the Figure 2;
: Figure 6 is a view similar to that of figure 2 illustrating a modification of the swaying apparatus shown in Figure 2; and Figure 7 is a view similar to that of Figure 2 illustrating a Further modification of the swaying apparatus shown in Figure 2.
Figure 1 shows a sleeve-like fitting 1 which is to be swayed onto a core 2.
The fitting may serve as the termination member of a conduit and the core is in the form of a flat wire metal conduit so that this conduit, together with a conduit to which the termination member may be connected, I
constitutes, after sieging conduit assembly. The fitting has a hexagonal configuration and the swaying operation is such that each race 3 is swayed, or crimped, inwardly at point 4 so that the fitting is mixed tightly to the core 2.
The apparatus by which the swaying is effected comprises a plurality of staging tools 21 in the Norm ox blades, each mounted for rotation about a pin 22 carried in a roller block 23 which in turn is mounted ox fixed frame member 24.
The swaying tools are arranged in a circle in three pairs with the tools of each pair opposed to each other. Each tool 21 has a forming race 25 which in cross section and side view have the profiles that will produce the desired configurations of the fitting after swaying. In the embodiments shown in the drawings, the profile of the forming face forms, in the length-wise direction of the fitting, an arc of a circle-; centered on the axis about which the tool swings and, transversely to this, as shown in Figure 5, the cross-section of' the worming face forms part ox a trapezoid.
The swaying tools together define a swaying station 26 having an entry side to the right ox a plane containing the fixed axes of the pins 22 as shown in figure 2 and an exit side to the let ox the plane. The tools 21 may swing prom the positions in which they are shown in Figure 2 to that in which they are shown in Figure 3. During that movement, they pass through the swaying station in which the separation between them is minimum and then the forming races, or edges, 25 :
` I I
of each of the tools 21 touch a circle of which the arm is transverse to the axis about which the tools swing.
A pusher means 28 comprising a piston (not shown) slid able in hydraulic cylinder 29 and connected by rod 30 to a plate 31. Plate 31 has an extension 32 thereon, the end of the extension 32 forming a cavity member 33 that serves as a socket to receive an end of the fitting 1. Movement of the piston rod 30 in the direction of the straight arrows drives the cavity member 33 to the left to force the fitting through the swaying station and, as will now be described, simultaneously operates the swaying tools 21.
Between each swaying tool 21 and plate 31 there is a pusher finger 40 to comprise a positive drive corn-scion between the plate 31 and the tool. Each finger 40 pivotal rests at its end 41 in the plate 31. As the plate 31 moves, the fingers 40 will move the tools through the zone in which swaying is effected, the pivot-in of the fingers permitting them to tilt as appropriate during this movement.
A compression spring 42 is provided for each finger 41 to ensure that the end of the finger 41 remains in contact with the plate 31.
Each tool 21 is connected to the plate 30 by a return spring 45 and urges each tool towards the position in which it is shown in Figure 2 so that it will return to that position after a swaying operation.
., Q3~.
In using the swaying apparatus that has been described, a conduit 2 having a fitting loosely embracing the end is moved to the right, as shown in the drawings through the swaying station 26 until the fitting 1 seats within cavity member 33... At this juncture the hydraulic. cylinder 29 is pressurized to move the plate 31 and the other components that are connected to it to the left, in the direction ox the straight arrows. Such movement causes the fitting to move to the let and the movement of the fingers 40 rotates the tools 21 so thaw the forming races 25 swing through the swaying station 26. The faces 25 initially contact the fitting 1 at the entry side ox thy swaying station, but continued movement of the fitting and swaying tools 21 results in a rolling action of the forming faces 25 on the fitting 1 with result .: -that the faces 3 of the fitting buckle in to swag, or crimp, the fitting 1 onto the core 2. Continued movement of the cylinder 19 pushes the witting beyond the swaying station to the position shown in Figure 3 at which point the-fitting is removed from the cavity member 33. The hydraulic cylinder, and the parts that move with it, return to their starting position and return springs 45 rotate the swag tools back to their starting position where the suckle may then be repeated.
In operation of the apparatus shown in figures
2 and 3, there may be a tendency sometimes for the fitting to be pulled away prom the cavity member 33 which can thus result in concentricity problems arising in thy swigged fitting. The reason for this is the effective change in radius of the swaying tools 21 between the points on the fitting 1 at which the forming faces 25 initially make contact with the outer 5 surfaces of the fitting and the points in the swaying station at which the forming faces 25 have most deeply impressed the faces 3 of the fitting of any pair are directly opposed to each other. The effective change in radius causes a difference in the peripheral speed 10 in the longitudinal direction ox the forming faces 25 and speed in the same direction at which the fitting is moved by the pushing means 50 that -the fitting is pulled out of the cavity member 33.
In order to compensate for this difference in 15 speed, a wieldable drive connection may be made either between the cavity member 33 and pusher means or between the pusher fingers 40 and the plate 31. Figure 6, where parts have similar to those occurring in the earlier figures have the same identifying numerals, illustrates 20 a modification of the apparatus by which a compression spring 60 is included in the cavity member 33 and in operation is abutted by the fitting 1. Any variation in the relative speed at the swaying station between the forming faces and the fitting 1 is taken up by -the 26 spring 60.
The modification illustrated by Figure 7 consists in the interposition between each of the pusher Fingers 40 and the plate 31 of a compression spring 65.
Where a spring is interposed either in the cavity member 33 or at an end of the pusher fingers 40, then part of the force exerted by the pusher means is absorbed by the spring.
A swag apparatus as described above swags the fitting by a roiling action rather than either by inclined sliding engagement ox a tool on the fitting ox by impact of a tool on the fitting with -the result that total energy required for the swaying process is less. The apparatus that has been described may be easily adapted for automatic feeding of the parts to the apparatus and automatic operation of the apparatus.
While the swaying apparatus as described is used for swaying a loose sleeve-like fitting onto a core, the device also can be used for forming ends of rods, cable, strands, flexible shafts and other articles.
