Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus capable of swaging sleeve-like slack joints into core soil.

A swage processing apparatus has already been proposed by JJM, which includes a plurality of forming dies surrounding an article to be formed, and in which a forming action is produced by the impact of the dies on the object. As a result, the total energy required for the die to strike the object with the sword required to deform the object is considerable, and the N a of the die in such a device is also high. . In addition, %lI'4i') may be used for other σ) articles, such as sleeve-shaped σ) joints which are coupled onto the core.
It would be difficult to apply such a device to something that automatically dispenses goods, such as a central office, which must be connected to a computer.

In an effort to reduce the forces acting on the die, it has been proposed to taper the die surface that engages the article so that the die gradually engages the article. Even so, the energy required to move the dice is considerable. SUMMARY OF THE INVENTION It is an object of the present invention to provide a swaging device which allows swaging to be carried out using force economically.

According to the present invention, there is provided a plurality of pivoted members that can simultaneously swing and pass through the swaging station, and in the swaging station, between the edges of the members that are far from the axis. [2] When the separation is minimal, each number of such edges is swaged into contact with a circle whose axis is transverse to the axis on which the pivoted support swings. Equipment is provided.

Next, specific examples of the present invention will be described by way of example with reference to accompanying drawings.

FIG. 1 shows a sleeve-shaped joint 1 to be swaged into a core 2-1-.

The fitting 1 serves as the end member of the conduit, and since the core is in the form of a flat metal wire conductor, this conduit connects the end After swaging together with the conduit that can be
A conduit assembly is formed. The joint t has a hexagonal shape, and in the swaging process 1'F, each surface 3 is swaged or shaped inward at a point 4 to firmly fix the joint to the core 2. .

The device in which swaging is carried out consists of a plurality of swage tools 21 in the form of blades, each tool LL carried in a roller block 25 mounted on a fixed frame member 24/hibin 22 It is mounted so that it rotates around the

;4-1---Five pairs of the machining tools are arranged in one circle, and the six pairs of tools face each other. Each tool 21 has a forming surface 25 having a contour, viewed in cross-section and side, to produce the desired shape in the joint f after swaging. In the four examples shown in the drawings, the contour of the forming surface forms an arc of a circle centered on the axis around which the tool swings in the longitudinal direction of the joint.
Transversely to this, the cross-section of the molding surface forms part of a trapezoid, as shown in FIG.

Each swage process d - taken together as shown in FIG. 26. The tool 21 can swing from the position shown in FIG. 2 to the position shown in FIG. During this oscillating motion, the tools pass through the swaging station, but the separation between the tools within this station is very small (-t at 7).
When C1↓, the forming surface of each tool 21, that is, the edge 25, is 1. The arm will touch the circle it traverses.

The suppression means 28 is configured to suppress pressure within the hydraulic cylinder 29.
The cylinder consists of a piston (not shown) which is capable of functioning and is connected to the plates 1 and 31 by rods 30. There is an extension 52 on the plate 1, and the 4i3 part of the extension 32 forms a cavity 33 which serves as a socket for accommodating the 9114 part of the joint 1. . When the piston rod 50 moves in the direction of the straight arrow,
112 member 551 is pushed through the swaging aesthetics and simultaneously actuates the swaging tool 21, as will be described next.

Between each screw pressing tool 21 and the play 51 there is a restraining finger 40 forming a positive drive connection between the play 1 and the tool 117.

The name finger 40 and its end 41) and the plate 31
I7 is seated with pivot support. When the plate 31 moves -2, the knee 1"L is swaged by the finger 40 and moved through the area 2), and by the rotation 11 of the finger 40 the knee 1"L is swaged through the area and j' Both are this luck 11f))
You can tilt it as much as you like.

Each finger 40 is provided with a compression spring 42 to ensure that the end 41 of the finger 40 maintains contact with the plate 31 σ).

Each tool 21 is connected to the plate 51 by a return spring 45, and is oriented to the position shown in FIG.
1 returns to its position after swaging.

When using the swaging apparatus described above, the conduit 2 having a fitting surrounding the end 9111 is swaged as shown in the drawings until the fitting 1 is seated within the cavity member 33. Move Est. 26 to the right. When this connection is made, the hydraulic cylinder 2
9 is supplied with pressure, causing the plate 31 and other components connected thereto to move to the left, i.e. in the direction of the straight arrow. Such a movement causes the joint to move to the left, causing the movement of Fimp, I40, jViJ+, l2, and J! ,
-21 rotates, the molding surface 25 swings, and -C 11 rotates.
- = Passing through the addition station. This side 25 i.
j - At first, the joint 1 and the swage contact each other on the entry side, but as the tool 21 continues to move further, the forming surface 251d exerts a roll action on the joint 1. As a result, the force is applied, so that the surface 5 of the joint 1 stops and the joint 1 is seated on the second 172, i.e., the force is
・You will have to pay 1. Cylinder 19 is also
Subsequent movement forces the fitting past the swage switch to the position shown in FIG. 3, at which point the fitting is removed from the cavity 35. The hydraulic cylinder and the parts transferred with it return to their starting position and return spring 45
The swage force rotates the tool back to its starting position [7], and then the above recycle can be repeated.

During operation of the barrel 2 shown in FIGS. 2 and 3, there is a tendency for the joint to sometimes be pulled out of the bore member 53, and this tendency is due to the concentricity that occurs in swaged joints. Sexual issues can be resolved in the end. The cause of this problem is the point on the joint where the forming surface 25 first contacts the outer surface of the joint and the point in the swaged varnishing where the forming surface 25 very deeply constrains the surface 6 of any pair of fittings. The effective change in radius of the swaging tool 21 between the swaging tool 21 and the swaging tool 21 is in direct opposite directions. If an effective change occurs in the radius, there will be a difference between the circumferential velocity in the longitudinal direction of the forming surface 25 and the velocity in the same direction at which the joint is moved by the pressing means, so that the joint will move in the cavity 3
It will be drawn from 3.

To compensate for this speed difference, a flexible drive connection can be provided between the cavity member 35 and the suppression means or between the suppression finger 40 and the play 51. In FIG. 6, the parts are similar to those in the previous figure and have the same reference numerals, but differ in that the compression spring 60 is housed within the cavity member 33. A variant of the wooden fR similar to that in Figure 1 is shown in Figure 1.
I'm here. In the swaged station between the forming surface and joint 1? Any fluctuation in the relative velocity of the motor is absorbed by this spring 6o.

The modification shown in FIG. 7 consists in interposing a compression spring 65 between the six pressing fingers 40 and the plate 31. If a spring is interposed within the cavity member 56 or at one end of the restraining finger 40, then a portion of the force exerted by the restraining means is absorbed by the spring.

The swaging device described above swages the joint by rolling action rather than by tilting the tool onto the joint and sliding it into engagement or by applying an impact with a pressure tool on the joint, resulting in swaging. The total energy required by the rod, v', is small for the devices described so far.
It can also be easily applied to devices in which parts are automatically supplied and operations are performed automatically.

Although the swaging equipment described above is used for swaging loose swaging joints onto cores, the swaging equipment can also be used to swage loose swaging joints onto cores; It can also be used to form the edges of and other articles.
