1 is a block diagram illustrating the process of the present invention.

In the method of manufacturing a cable chain used to protect and maintain a cable, such as a wire drawn into the inside while reciprocating a certain distance in a straight line and curve,

The present invention is an extrusion molding process for integrally extruding a body having a side plate formed through a conventional extrusion machine or the like so as to form a cover rib for supporting the wires inserted into the upper side toward the inside of the bottom plate so as not to be separated (S1). )and;

A cutting step (S2) of forming a cutting line by cutting with a general cutting machine at regular intervals such that an upper part of the side plate of the extruded main body is squeezed and opened after the extrusion molding process;

After the cutting process is shown to be made of a perforating process (S3) for drilling the through-holes in a conventional manner to the side plate close to the bottom plate around the cutting line.

Therefore, the side plate of the bent portion during straight and curved reciprocation of the main body is easily opened and narrowed through the cutting line and the through hole.

On the other hand, in the extrusion molding process, the partition plate forming step (S1a) to integrally form one or more partitions with cover ribs formed on both sides of the top plate as a bottom plate between the side plate and the side plate, a plurality of partition walls between the side walls It is desirable to partition so that the cable can be selectively introduced.

2 is a perspective view showing the present invention, Figure 3 is an enlarged cross-sectional view of the main portion of the A-A line according to FIG.

In the cable chain 1 used to protect and maintain a cable such as an electric wire drawn inward while reciprocating a certain distance in a straight line and a curved line as shown,

The main body 10 is integrally formed with a side plate 14 formed with a cover rib (14a) to prevent the separation of the cable in which the upper end is drawn inward to both sides of the bottom plate 12;

The side plate 14 is formed to form a plurality of through-holes 16 at regular intervals in close proximity to the bottom plate and the cutting line 18 cut to open the upper side from one side thereof is formed.

In addition, the bottom plate 12 between the side plate 14 is formed with a cover rib 142 for supporting the cable to be inserted into the upper both sides so as not to be separated, the through hole 144 corresponding to the through hole and its penetration The partition wall is divided into two sides between the side plates by integrally forming the partition wall 140 in which the cutting line 146 cut to the position corresponding to the cutting line is formed so that the upper side is twisted and opened from one side of the ball. It is desirable to be able to pull in.

In addition, by forming a plurality of the partition wall 140 between the side plate in the bottom plate 12, it is possible to introduce the cable associated with the required position so that the operator can be carried out more smoothly. desirable.

Figure 4 is a side view of the main portion showing a state of use of the present invention.

As shown in both ends of the body 10 formed integrally of the cable chain (1) having the above configuration by using a fixed bracket (B) as a general fixing means fixed by a device requiring a reciprocating repeated movement of a certain distance The cable is to be introduced by pushing the cable to be drawn between the side plate and the side plate or between the side plate bulkheads or by opening the side plate.

Then, as the device is driven, the main body of the cable chain reciprocates in a straight line or a curve. At this time, the upper part of the side plate 14 of the bent portion A according to the reciprocating motion is squeezed and penetrated through the open cutting line 18. The bent by the ball 16 is to be opened to the smooth bend is made, the straight portion of the bent portion of the side plate that is opened again is narrowed to abut.

Accordingly, as the main body constituting the cable chain is integrally formed, vibration or friction noise is not generated at all in the curved portion of the main body in a straight or curved reciprocating motion, and there is no friction so that dust is not generated due to friction. You have a condition.

In addition, as the main body constituting the cable chain is integrally extruded, the overall weight of the cable chain is also reduced, and there is a condition that a smooth reciprocating motion of the cable chain can be achieved even with a small power.

As described above, in the present invention, in forming the cable chain, the main body is integrally extruded and the curved cutting line and the through hole formed by the side plate can be smoothly bent, so that the overall weight of the cable chain is reduced and small. The reciprocating motion is smoothly performed by the power, and the vibration and friction noise are not generated by the cutting line and the through hole during the straight line or the curved reciprocating motion, and the dust generated by the friction is also generated.

In addition, even when the cable is introduced into the main body of the cable chain can be divided by the partition formed by the bottom surface formed between the side plates, there is also an effect that can be made easier for the operator cable entry.
