Description

[Detailed Description of the Invention] Industrial Application Fields The invention is directed to a tightening device for tightening a cylindrical material from its outer peripheral surface with a uniform force in the circumferential direction.

<Prior art> When connecting cables, pipes, etc. that have armored edges, it has been considered to use a new armored connection sleeve as shown in Figure 3 as a means of connecting armored wires to each other. This exterior has 9 sleeves.

A large number of outer edge insertion holes 03 are provided at the ends of a pair of sleeve members 02 that can be accessed to the turnbuckle support 01, and parts other than the outer wire are inserted into the cavity 04 of the sleeve member 02. At the same time, the outer wire is inserted into the outer edge insertion hole 03, and the outer edge thereof is crimped to fix the outer device k.

By the way, what about the above armor sleeve? Is the mail packaged? In order to securely fix the outer wire connecting sleeve, it is desirable to apply a uniform tightening force in the circumferential direction of the outer circumference of the sleeve member end. ? It can be used effectively.

Have you ever used cylindrical materials? As a means of making the outer circumferential surface uniform in the circumferential direction, a jig r is applied to the circumferential surface of the cylindrical material, and the jig r is pressed in two directions. To repeat with a different variation, there is a generally known method of tightening η1 over almost the entire circumference of a cylindrical material.

However, this method requires the troublesome work of changing the direction of the circular material or the press machine, and it also requires repeating the punching process, which requires time and effort.
There is also a manual method for tightening other swords, but of course, because it is done by hand, the tightening is not uniform.
? ]l-It ends up being necessary.
