Riveted joints are made of special parts. So still a bond hard to break. Rivets themselves are made of plastic material.

Structure

Riveted joints consist of three elements:

  • Two parts of the parts;
  • Rivet.

The Last element is placed in the special holes located on the edges of the parts. riveted jointsRivet holding in the required position. In this case, the adapter element has this structure:

  • Body;
  • Pin;
  • Mortgage head – used for the formation of future products;
  • Locking head – is formed in the process of joining two elements.

For clamping large workpieces use a huge amount of rivets. In this case, the finished connection is called rivet seam.

Scope

Before the advent of high-quality welding, riveted connection details were wide spread. It is currently used in some areas of technology. Riveted connection details used in the construction of aircraft, ships, submarines, and various precision instruments. In addition, the rivets used for connecting building elements, such as I-beam, channel, angle. riveted connection detailsThey help to sustain the variables vibratory loads. Riveted joints are used to combine different types of material. For example, for fastening articles of iron alloy with aluminum sheet.

Riveted joints. Advantages and disadvantages of the method binding

Among the positive aspects are:

  • Simple technological performance;
  • The ability to join different metals;
  • High reliability of the connection;
  • Prevents vibration and shock loads.

However, as every connection has its drawbacks, among which are the following:

  • To create a rivet fastening is necessary to spend a large amount of metal;
  • Requires substantial labor costs;
  • High cost;
  • Riveted joints can deteriorate due to incorrect diameter of the holes that are on the edges of products;
  • In the process of operation, tightness of connections is reduced.

Types of riveted joints quite a lot, as each of them applies in a particular industry.

Riveted joints: types

This type of connection is shared on this principle:

1. The functional purpose. Among the compounds there are three types: durable used for holding large loads; thick, which ensure tightness; combined – with both functions.

2. Technology seam construction. The connecting stitch can be lapped and butt. riveted connection details applyThe Last type is performed using one or more overlays.

3. The number of slices. This indicator shows the number of slices passing through one rivet under load. According to this principle riveted joints are one - and mnogocwetnye. Their number is not limited.

4. The number of rivet rows. They may be one, two, three, etc. the Number is not limited.

As mentioned earlier, riveted joints are used in various industries. Therefore, there are different types of rivets. In addition to these indicators, these types klassificeret in the form of mortgages of heads:

  • Polukrovka;
  • Patina;
  • Polupoltina;
  • Tsilindricheskoi.

Sterzing

According to its form divided in the following types:

  • Solid;
  • Hollow (have a through-hole);
  • Semi-solid – the rod is divided into two parts: one is solid and the other – hollow.

Basic information about the bonds and the composite elements are contained in the standard documentation. riveted joints advantages and disadvantagesCharacterizing riveted joints GOST 10303-68 includes the basic layout of the rivet. It is outlining its diameter, body length and stud, as well as the head.

Material production

The Main materials for the manufacture of riveted joints are mild steel, non-ferrous metals and some alloys. Despite this, each material must meet stringent requirements:

  • To facilitate the installation of the product material should be plastic.
  • Materials should have similar thermal index of expansion. Failure to comply with this requirement, when the temperature changes will lead to additional tension. In the end, the riveted joints are destroyed.
  • Materials must be homogeneous. This is to ensure that the galvanic current did not destroy the connection. For example, for fastening steel parts are used steel rivets, copper items – copper, etc.

Loading

Valid was determined by numerous tests and experiments. In addition, they have been carefully studied by specialists. riveted joints is used forThere are several types of loads:tension shear, tension and bearing strength. For each type of metal these indicators differ from each other.

When using two elements of low-carbon steel permissible tensile load must not exceed 150 MPa, and the voltage of the slice to be no more than 100 MPa.

It Should be noted that these indicators have been developed not only for connecting elements, but also for the rivets. riveted joints GOSTThey have their allowable load. For example, for the production of carbon steel tension shear should not exceed 100 MPa. Crushing it is no more than 300 MPa.

Allowable load for the elements depend on the method of making holes in the products. riveted joints classificationIf there is a large voltage, the holes should be made by drilling.

In the case of temporary impact on the product the permissible load is reduced by 20 %. In some cases, such as when a cold rivet, this figure is reduced by 30 %.

Recommendations for the production of rivet connections

These terms of making connections was developed by highly qualified professionals. They were identified as a result of years of testing in the laboratory and in the operation of the connection. So, among them there are:

1. Fittings and rivets should be made of a solid homogeneous material.

2. Rivets must secure to a small value, the weakening between the parts. For this purpose, as a rule, using the chess method of consolidation.

3. You should avoid bending the main structural elements. This rivet features for the axis, which passes through the center of connected elements.

4. On one rivet connection it is impossible to use elements that have different diameters.

5. To avoid rotation of the parts, the number of rivets should be not less than two.

6. The number of elements on one side should not be more than three. With the increase of this indicator the strength of the product will decline.

7. When a butt connection is necessary to use more studs compared to the splice site.

8. It is necessary to ensure tightness. For that, the field rivets are applied with a special glue or paint, which are obtained by means of flame spraying.

9. After fixing parts are checking.

10. The number of studs depends on the developed project riveted joints.

This connection is not very common nowadays. It is almost completely replaced welding. riveted connection details applyBut it is used in the manufacture of aircraft, ships, and also some devices. The main advantages are high durability of the finished joints and easy installation. However, to use it, you need to spend a significant amount of metal. Therefore, this type of connection is expensive and time consuming.

Conclusion

Riveted joints there are a large number. riveted joints is used forBasic types and sizes of rivets specified by the regulations. The kind of element depends on the industry. Their installation requires precise execution. The slightest deviation in the diameter of the hole can lead to the destruction of the entire product. riveted joints advantages and disadvantagesIn their manufacture must follow some rules, which were drawn up by experts based on years of calculations and conducted experiments.

So, we have considered the peculiarities of this type of compounds.
