When the bent portions are manually formed at both ends of a linear member, the work is complicated, and the method is not suitable for mass production and lacks economic efficiency.

In particular, when changing the seat design, the length and thickness of the wire changes, or when using wire for different parts, wires of various lengths and thickness are required. However, it has the drawback that it is complicated to manufacture various wires of different lengths and thicknesses. Furthermore, it was not possible to accurately bend the ends of the wires at predetermined positions, resulting in variations.

The purpose of the present invention is to be able to easily and quickly form continuous bent portions at the ends of a large number of linear members such as wires, without the risk of variations in the size of the bent portions, and to form uniform bends. A linear member can be obtained,
Another object of the present invention is to provide a terminal bending device for a linear member that can continuously form bent portions using the same device even when the linear members have different lengths and thicknesses.

The movement of the fixed bases 55 and 56 by the moving means is performed, for example, by rotating a rotating handle 57. A screw shaft (not shown) is connected to the rotary handle, and a movable member that is screwed to the screw shaft and moves in the left and right direction according to the rotation of the screw shaft is attached to the bottom surface of the fixed bases 55 and 56. are fixed to each.

The fixed bases 55 and 56 have linear member receiving parts 26,
Aligning mechanism 61 and second transfer means 3 to be described later
1. Bender parts 36 and the like are attached to each of the parts, so that the spacing between these parts can be adjusted depending on the length of the linear member 1 to be processed.

The linear member receiving portion 26 includes an inclined surface 27 and a stopper member 28 provided below the inclined surface 27, so that the linear member 1 transferred by the first transfer means 17 falls onto the inclined surface 27. Then, the inclined surface 27
The wire members 1 roll downward along the line, are received by the stopper member 28, and the plurality of wire members 1 are placed in parallel.

As shown in FIGS. 6 and 7, alignment mechanisms 61 for aligning the ends of the linear member 1 are provided outside both sides of the linear member receiving portion 26. As shown in FIGS. This alignment mechanism 6
1 includes a cylinder 62 attached to the fixed bases 55 and 56, a connecting rod 63 driven by the cylinder 62, and a pressing plate 64 pivotally attached to one end of the connecting rod 63. is normally located outside the end of the linear member 1, and its lower end is pivotally supported by a support rod 65, and when the cylinder 62 is driven, the connecting rod 63 moves up and down, and the pressing plate 64 sets the linear member. 1

It rolls along the formed inclined surface 34 and is transferred to the bender section 36. An arm portion is provided in place of the vertical elevating member 33, and this arm portion is rotated by a rotation mechanism to raise and lower the vertical elevating member 3.
It is also possible to form an inclined surface similar to that of the inclined surface 34 of the upper end surface of No. 3.

FIG. 3 schematically shows the bender section 36, and in this embodiment, the bender section 36 is provided with a pair of left and right rotating members 37, 38, and is capable of bending both ends of the linear member 1 at the same time. However, the bent portion 2 can be formed only at one end of the linear member 1 by omitting one or not operating the other.

The longitudinal intermediate portion of the linear member 1 is held by a fixing portion 39 formed in the shape of a presser claw, and a pair of rotating members 37, 38 are arranged. The rotating members 37 and 38 consist of a rotating shaft 41 supported vertically, a center pin 42 projecting from an upper end on the axis of the rotating shaft 41, and an end of the linear member 1. The bending pins 43 are protruded at intervals into which the bending pins 43 can be inserted.

As shown enlarged in FIGS. 4A and 4B, the bending pin 43 is formed into a truncated cone shape with a thin upper end and a thick lower end, and a bearing portion 43a is formed at the lower end of the bending pin 43. There is. The upper end opening on the entrance side is widened so that when the linear member 1 is dropped from above, it can be inserted reliably between the center pin 42 and the bending pin 43. Furthermore, when the diameter of the linear member 1 is small, it is inserted so as to come into contact with the upper end of the rotating shaft 41, but even when the diameter is large, it is supported above the tapered surface of the bending pin 43,
Linear members 1 of different thicknesses can also be inserted. Furthermore, in the case of the linear member 1 that comes into contact with the bearing portion 43a, it is possible to process the linear member 1 in a state where the frictional resistance is significantly reduced.

The rotating shaft 41 of the bending pin 43 is arranged so as to be positioned symmetrically in a direction orthogonal to the longitudinal direction of the linear member 1. And the rotating member 37,
38 is rotated, for example, by 180° in the opposite direction.
That is, the rotating member 37 is rotated counterclockwise.
8 is rotated 180° clockwise, both ends of the linear member 1 are bent inward, and in this case, due to the presence of the bearing portion 43a, there is little frictional resistance and the bent portions 2 are easily formed at both ends. (See Figure 4B). The bending pins 43 are not limited to being rotated symmetrically, but may be rotated in the same direction.

In this embodiment, a pair of left and right rotating members 37, 38
The explanation has been made on the case where the rotation shaft 41 is formed by the center pin 42 integrally formed to protrude from the rotation shaft 41, and the bending pin 43, but since the center pin 42 does not need to rotate, only the bending pin 43 is used. For example, the center pin 4 can be configured to be rotated.
A rotary cylinder serving as a rotary shaft 41 having a bending pin 43 protrudingly formed on the shaft body formed with the bending pin 43 may be rotatably fitted, and the rotary cylinder may be rotated.

After forming the bent part 2 at the end of the linear member 1 in the bender part 36, the cylinder mechanism 46 and the arm 47 are inserted into the product storage part 51 from the bender part 36.
It is transferred by the third transfer means 45 having the following.

The bending portion 2 of the linear member 1 is formed continuously through each mechanism, and each of these mechanisms is operated by a drive control mechanism (not shown) housed in the controller box 14.

[Effect of idea]

The above is the configuration of an embodiment of the apparatus for bending the end of a linear member according to the present invention. It is possible to continuously form bent parts one by one at the ends of the member, and it is also possible to easily respond to design changes in the length and thickness of linear members, making it possible to bend parts of linear members of various lengths and thicknesses. Compared to forming bent parts one by one by hand, this method of linear members can significantly improve work efficiency and is also safer and more economical. A terminal bending device can be obtained.
