Definitions

  • This invention is concerned with apparatus by which a loose sleeve-like fitting may be swaged onto a core.
  • Swaging apparatus which provides a plurality of forming dies surrouding 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 considerable and die wear in such a apparatus is high.
  • An object of the invention is to provide a swaging apparatus by which swaging can be effected by the economical use of force.
  • swaging apparatus including a plurality of pivoted members which can swing simultaneously through a swaging station, in the swaging 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 edge is touched by a circle of which the axis is transverse to the axes about which the pivoted members swing.
  • Figure 1 shows a sleeve-like fitting 1 which is to be swaged 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, constitutes, after swaging,a conduit assembly.
  • the fitting has a hexagonal configuration and the swaging operation is such that each face 3 is swaged, or crimped, inwardly at point 4 so that the fitting is fixed tightly to the core 2.
  • the apparatus by which the swaging is effected comprises a plurality of swaging tools 21 in the form of blades, each mounted for rotation about a pin 22 carried in a roller block 23 which in turn is mounted on fixed frame member 24.
  • the swaging 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 face 25 which in cross section and side view have the profiles that will produce the desired configurations of the fitting after swaging.
  • the profile of the forming face forms, in the lengthwise direction of the fitting, an arc of a circle centred on the axis about which the tool swings and, transversely to this, as shown in Figure 5, the cross-section of the forming face forms part of a trapezoid.
  • the swaging tools together define a swaging station 26 having an entry side to the right of a plane containing the fixed axes of the pins 22 as shown in Figure 2 and an exit side to the left of the plane.
  • the tools 21 may swing from 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 swaging station in which the separation between them is minimum and then the forming faces, 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) slidable 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 swaging station and, as will now be described, simultaneously operates the swaging tools 21.
  • each swaging tool 21 and plate 31 there is a pusher finger 40 to comprise a positive drive connection between the plate 31 and the tool.
  • Each finger 40 pivotally 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 swaging is effected, the pivoting 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 swaging operation.
  • a conduit 2 having a fitting loosely embracing the end is moved to the right, as shown in the drawings through the swaging station 26 until the fitting 1 seats within cavity member 33.
  • the hydraulic cylinder 29 is pressuirized to move the plate 31 and the other components that are connected to it to the left, in the direction of the straight arrows.
  • Such movement causes the fitting to move to the left and the movement of the fingers 40 rotates the tools 21 so that the forming faces 25 swing through the swaging station 26.
  • the faces 25 initially contact the fitting 1 at the entry side of the swaging station, but continued movement of the fitting and swaging tools 21 results in a rolling action of the forming faces 25 on the fitting 1 with a result that the faces 3 of the fitting buckle in to: : .swage, or crimp, the fitting 1 onto the core 2.
  • Continued movement of the cylinder 19 pushes the fitting beyond the swaging 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 swage tools back to their starting position where the cycle may then be repeated.
  • a yieldable drive connection may be made either between the cavity member 33 and pusher means or between the pusher fingers 40 and the plate 31.
  • a swage apparatus as described above swages the fitting by a rolling action rather than either by inclined sliding engagement of a tool on the fitting or by impact of a tool on the fitting with the result that total energy required for the swaging 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.
  • the swaging apparatus as described is used for swaging 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.
