Mounting cartridge: application features

Mounting guns were finealternative to manual labor in difficult conditions, when you need to work with a solid foundation. This tool has several advantages. Clogging of dowels-nails, using construction mounting cartridges, occurs without preliminary drilling of the base, and this not only makes work much easier, but also saves time for one operation. Such pistols operate without an electrical network, which allows them to be used in the field.

Varieties of pistols

Although there are several types of suchtool (gas, pneumatic and powder), the mounting cartridge is used only in the latter. Structurally, it is close to firearms and operates according to a similar principle, therefore, basically, it is produced in weapons factories. Accordingly, the quality is confirmed by well-known world brands - TOZ, Walter, Spit, Remington, Hilti and others.

mounting cartridge

Also, the pistols are subdivided by the type of feedcartridges for: single-charge (manual feed), semi-automatic (cassette-disk) and automatic (cassette). The most productive are the latter, which can make about 700 connections per hour.

To perform specific tasks, for example, forroofing works on metal structures, installation of corrugated sheets or waterproofing of tunnels, work with concrete, low-carbon steel, fastening of metal grilles, special designs of pistols are produced.

The mounting cartridge used in suchpistols, single. However, safety must always be observed when working with this tool. The apparatus itself is disassembled, inspected, cleaned and lubricated approximately every half a thousand shots.

Mounting cartridge: principle of operation

Principle of operation of all mounting gunsthe same, only in powder dowels is hammered by the piston, which drives the force of the explosion of the cartridge. The force of action on the dowel is selected in accordance with the density of the substrate into which it is driven. It can be adjusted either by choosing the power of the cartridge, or by mechanical means, if this is provided by the design of the gun.

Assembly mounting cartridges

Barely bullet (single) mounting cartridge has the formA sleeve whose open end is rolled and colored with a color marking corresponding to the power. He is charged, as a rule, with smokeless powder. Ignition and explosion occur after striking the striker on the primer-igniter.

In some cases, there are also constructions of an assembly cartridge equipped with a Berdan and Boxer capsule (used in military shells).

Gunpowder guns can not be used for installation work, in which materials such as glass, ceramics, cast iron, curbstone and granite are involved.

Caliber and capacity of cartridges

Different brands of gunpowder guns are charged with their types of construction and assembly cartridges, which differ in caliber and power.

mounting chuck 56

The most popular calibers for semi-automatic andautomatic pistols - 6.8 x 11 and 6.8 x 18. And in single-shot pistols such as Hilti DX E72 or GFT307, a 56 x 16 mounting chuck is used. All of them are subdivided according to the discharge power, which is indicated by means of a special color marking (yellow , red, blue, gray, black or green). Color identification is repeated and on the package with cartridges.

A particularly important point is the right choicepower, because this will depend on the reliability of the connection. So, for example, for clogging a dowel-nail in a brickwork or a plastered wall, the power is up to 500 J, but it is possible to cope with a steel or concrete base with the impact force exceeding 500 J.
