The aluminum sleeve D180xd, AK 7, AK 12

The aluminum sleeve D180xd, AK 7, AK 12 is a connecting product with a tubular section and is used to seal the ends of the ropes using a specialized press. In most cases, these parts are used to form and secure loops formed from rope slings.

GOST TU - 1583-93.

L, mm - up to 500.

Aluminum sleeve - a metal product used in crimping ropes that were made of steel. The application of the product can be observed in the production of rigging and lifting products. Based on this part, you can make one large rope from separate parts, or create loops.

When using the part for its intended purpose, attention is drawn to the fact that before crimping, the sleeve does not contain damage of the following nature:

     nicks;

     dents;

     other mechanical damage.

The parameters of the sleeve during production are determined by the type and size of the rope for which it will be used. Other parameters are also taken into account, for example, diameter, type of core, as well as temperature conditions in which the sling will be used. Based on taking into account all the above characteristics, the manufacturer can provide a high-quality product that will comply with all GOST standards and perform the functions assigned to the part.

Fixing the product on the rope is carried out according to one standard - pressing. This feature can be attributed to the disadvantages, since for an effective connection it is necessary to have a special press, which will be characterized by the presence of high pressure on the rod. Also, a set of matrices will add versatility to such a press. They are necessary in order to be able to carry out the process of pressing bushings of different sizes and parameters.

Bushings can only be used in specially equipped workshops due to the fastening features. To achieve the desired success is possible only with the ideal geometry of the part and uniform compression. In the field, such a result is impossible to achieve.

However, there are also advantages of connections that were made on the basis of an aluminum sleeve. The advantages include:

     low cost;

     high speed of work;

     maximum joint strength (when fastened in the right conditions);

     long-term operation;

     the finished joint is characterized by small dimensions.

It is important to note the fact that aluminum bushings belong to a number of disposable parts, and they are not suitable for reuse.

Bushings are used in the manufacture of rope slings for sealing the ends of the rope by crimping. The sealing of the ends of the ropes with a spigot is a pressed construction of an aluminum sleeve with strands of ropes to be connected, which are firmly linked to each other by the metal of the sleeve, forming a homogeneous body in cross section.

The surface of the sleeve before pressure testing should not have nicks, dents or other mechanical damage. The correct type and size of the sleeve is selected based on the design of the rope, its diameter, the type of core of the rope, the material of the rope, and the temperature conditions of the sling.

Any aluminum bushing must meet quality standards. For this type of rolled metal, the DIN 3093 EN 13411-3 standard is applied, which strictly regulates what materials this product can be made of, as well as what overall dimensions it can have. The dimensions of the aluminum bushings depend on the cables they are to be used with. So, you can choose the right option for metal cables from 8 mm in diameter to 46 mm.

Among the forms of bushings, cylindrical, cylindrical rounded, cylindrical conical are distinguished. The correct dimensions of the bushings are selected in strict accordance with the nominal diameters.

In this case, the parameters of the bushings are always calculated for the maximum weight that the slings can withstand. The design indicators strictly determine the force of crimping and the entire cycle of the technological process itself. This is what allows us to assert that the aluminum bushing is a reliable hinge connection that can last for the longest period of operation.

Advantages of aluminum bushings

Quasi-statistical tensile tests were carried out, during which it was found that slings that were pressed with an aluminum sleeve were able to withstand 85-100% of the breaking force of the applied steel rope. In tests, they were able to withstand an average of 60% of the stretching cycles of the rope clamps.

The operating temperature for aluminum bushings used on ropes made of steel with organic cores is the range from -60 to +100 C, and +150 is acceptable.
