A special tool is used to join various dense fabrics, synthetic materials, as well as sheets of metal and wood. It is a riveter that reduces user labor and does its job well.

Description and principle of operation

The pneumatic riveter is a special tool whose function is to install blind rivets and rivets. The tool is highly durable and vibration-resistant . The result of his work can be compared to spot welding. It is widely used in professional activities and in everyday life. To work with this tool, it is necessary to attach the materials to be fastened to each other and drill a through hole in the right place.

First, we select a sleeve of the required size for the riveter so that it matches the circumference of the rivet rod, then insert it into the tool and secure it with a wrench. We set the rivet with a rod close to the surface so that the tip completely enters the hole . We inspect so that on the other side the head looks out at least 1 cm. Slowly press on the riveter until it comes into full contact with the head and remove the lever several times until the leg is formed.

The moment you feel the lack of resistance, remove the tool.

Pros and cons

The pneumatic riveter has a lot of positive characteristics. With its light weight and size, it has a great pulling force . Even models weighing up to 2 kg have a pulling force of 15,000-20,000 N and more. Thanks to these indicators, it is possible to install steel rivets with a diameter of 6, 4 to 6, 8 mm. They are very easy to use and the performance is high.

More than a hundred rivets can be installed within an hour without exposing the user to physical exertion . These devices do not contain rechargeable batteries, which significantly saves operating time. The result of labor is a high-quality connection with durable and reliable indicators.

Thanks to this tool, you can work with critical details.

Sure, in using this device, you can find some disadvantages . For work, it is necessary to use special air hoses, the length of which may sometimes not be enough. These hoses are connected to the compressor, therefore the pneumatic tool is used only in stationary conditions. If a malfunction occurs or the installation of pneumatic equipment is needed, then repairs must be carried out only by an experienced specialist, and this will entail large financial costs.

To avoid premature malfunctions, the tool must be serviced periodically: lubricate the parts, tighten the connections to ensure tightness . Despite this, air guns are popular in the automotive industry and assembly lines. They are very often used in the manufacture of metal structures in construction.

Also used for the assembly and repair of ships, agricultural machinery and other structures.

Species overview

Pneumatic riveters come in different types. For example, pneumohydraulic or simply hydraulic is used for large threaded rivets in industry . Such options carry out fastening of parts with high downforce. Mostly used in mechanical engineering.

Hydraulic pneumatic riveter AIRKRAFT designed to work with aluminum rivets and stainless steel. Performs professional riveting in a continuous process. The design is equipped with a double air intake, which allows for both right and left hand operation. There is a special container with a rim to protect the user's eyes and keep the workplace clean. This design is designed to minimize hand fatigue.

A muffler is provided, and a special tip design has been created to avoid rivet loss . There is also an oil filling hole. For work, you must use an air hose with a diameter of 8-10 mm. During riveting, the air consumption is 0.7 liters per unit. The power is 220 Hm. Stroke length - 14 mm.

Also, pneumatic rivets can differ in their purpose and performance, they can be used to install blind rivets, threaded rivets or nut rivets. The Taurus-1 model of pneumohydraulic rivet drawing tool has a light weight (1.3 kg), the air consumption is 1 liter per rivet with a working stroke of 15 mm . The rivet will be held in any position thanks to a special switchable suction system. The receiver uses compressed air to install it and eject the tear-off rods.

A pressure relief safety valve is also provided . During operation, there is minimal vibration and noise level, the weight distribution is optimal. There is a retractable gimbal holder. The model is equipped with a handle with a rubber insert. The blind riveter carries out work on the installation of blind rivets. The main advantage of this type is the low price of consumables. Rivets of this type cover the hole of the workpiece well.

The tool has a simple design and is considered the most common.

The threaded version works a little differently, it is designed for threaded rivets . This type is a shallow tube, at one end of which there is an internal thread, and the other side is flaring, like a blind nut. A stud is screwed into the thread. Pulling towards itself, the thin metal between the thread and the flaring is crumpled, as a result of which it firmly compresses the parts to be joined. These connections are highly durable, but the cost of such rivets is much higher than the previous version.

There are also universal pneumatic guns that work with rivets and threaded type at the same time. The set includes replaceable heads and instructions. The JTC Heavy Duty Air Riveter has the following dimensions: length - 260 mm, width - 90 mm, height - 325 mm, weight - 2 kg. Air connection size is 1/4 PT. The tool is designed to work with rivets made of aluminum and stainless steel.

Easy and simple operation is guaranteed by the two-component handle . The working part is made of chrome vanadium steel, due to which the tool has a long service life. To increase productivity, you can work with two hands. This model belongs to the professional and industrial class. The quality of the products is confirmed by an international certificate.

The collet gripper guarantees precise and reliable operation of the pull-out mechanism.

How to choose?

To choose a pneumatic riveter, it is necessary to initially assess the scale of work and the effort required for this. The tool must be quiet and lightweight . Depending on the work, you can choose a tool for blind rivets or threaded rivets. It is necessary to select a product based on the diameter of the elements. If the air gun is selected for a smaller size, then you will not be able to fix the part well. When choosing a model, you need to take into account the length of the workpiece.

Power is a very important indicator for this tool, so you need to choose a model with the maximum this parameter . It makes it possible to work with large rivets made of hard materials.

As for the air flow rate of the pneumatic riveter, this indicator should be 20% lower than the similar characteristics of the compressor . Semi-professional models are made of more durable metal, capable of working for a long time and making fasteners. Very often, these models have a swivel head, which facilitates easy work in hard-to-reach places. Also, products can have lengthened lever arms, thanks to which the user makes less effort, and the work goes faster.

This option will be the most expensive.

Operating tips

To work properly with the impact tool, you should always use only good quality rivets. Accordingly, they are the most expensive. Cheap options do not have good characteristics, and when the sleeves are tightened, their rod may break out ahead of time . As a result of this work, the rivet does not fit tightly to the hole, and the blade material does not bond well. When using the tool, you need to remove the fallen rivet shafts, as they are very sharp at the cut point and can be absorbed into the soft surface.

Rivets equipped with special ponytails can be magnetically assembled.
