Each person at least once in his life came across the problem of spinning or spinning the nut. For small parts, spanners are used, and here for large works requires a device more serious. At car maintenance stations and in the construction sphere, drums are used.
These tools are able to significantly reduce the time for dismantling and installing the twisting element. At the same time, it does not even have to use oxidative fluids, it is enough to keep the device smoothly so as not to cut the thread.
Appointment and principle of work
Impact wrench – tool intended for installation and dismantling threaded elements. In general, it is used in working with nuts, bolts of various species and anchors. The main feature of the device is in a powerful torque, which disconnects the parts by a threaded compound, while no physical effort from a person is attached.
Impact wrench is used in large-scale work, where people will not have enough forces.
The power of the mechanism exceeds the energy used by man hundreds of times. Accordingly, the work process is significantly reduced by time.
This tool is designed and designed not only for industrial works, but also for household needs.
Impact wrench is often found at the automotive plants. It is this unit that plays an important role in the process of collecting carcass design of cars.
Many workshops of construction have acquired various wrench for production needs, and on tires without this device any work is delayed for a long time.
To date, you can meet many varieties of drum guides, but all of them are similar to the principle of work and technical characteristics. The appearance of the wrench is largely reminiscent of a construction screwdriver or drill. But the filling itself has cardinal differences. Instead of the cartridge with a clamp in the wrench, a special spindle is used. On it just installed heads with different sizes.
The tool reducer turns the human impact into a technical force, due to which the element is screwed.
In addition to the twisting point, the wrench has a reverse move, with this device you can dismantle and install threaded elements. In this case, the speed of rotation of the mechanism of the wrench does not change.
It is important to note that various nutrition is applied in different models of wrench. For example, a network or electrical requires a connection to 220 volts, while the output of the device’s power on average is 380 W.
Special automotive wrench connected to 12 volts through the cigarette lighter, But on the torque, the low current supply is not reflected in any way. Air or pneumatic wrench must be connected to the compressor.
Impact wrench, in addition to different ways of nutrition, have different sizes, which determine their main use. Standard nuts in botov use can be dismantled and installed with a spindle with a ½ inches size. But for large works used tools of large sizes, where the spindle size is ¾ and 1 inch.
Advantages and disadvantages
Studying the detailed characteristics of the drum guides, it becomes clear that there are several modifications of data tools on the market. Each model has its own specific advantages and disadvantages that everyone should be known.
Electric wrench have higher demand. Their main advantages are in the low noise level, high power of the rotating element, affordable price and high efficiency.
In addition, the electric species of the instrument has several flaws.
- During operation, the wrench heats up strongly, especially in the summer, when the sun shines brightly. Of course, in the system of the device, the cooling fan is provided, but, unfortunately, it is not in all models, it copes with his work. It follows from this that the long-term use of the electric wrench is prohibited. Tool need to give time to cool.
- Electrical models have a limited scope of application. In no case cannot be used in a wet environment or on the street during the rain.
Rechargeable wrench Mainly used to solve household problems. They are autonomous, radiate low noise during operation, have a smooth adjustment mechanism and are very useful at home.
Despite the impressive list of advantages, rechargeable models have several flaws.
- This device will not be able to help a person perform a large amount of work. The resource of such tools is designed for minimal activity. And all due to the weight of the battery. This does not mean that the wrench has a major mass, just a person will quickly begin to feel a sense of discomfort and strong tension in hand. That is why for long work, manufacturers have developed separate models, which are much easier and more convenient in hand.
- Almost every accumulator wrench has another battery, but high-quality goods are offered on the market. A fairly often acquired battery has a low charge margin, although a different digit is indicated on the package.
Hydraulic wrench We produce several manufacturers and this is quite enough for this type of tool, since their full use is carried out exclusively in production scale. From the technical side, they have high power, can unlock even rusty fastes, resistant to dampness and water intake and have smooth adjustment of the clamp.
The only drawback is the price. But for life, hydraulic wrench will not fit.
Pneumatic wrench in appearance similar to electrical models, while have a number of additional benefits. The powerful power of the pneumatic tool is at times exceeds the power of the electrical device. The housing of the pneumatic wrench is much easier, and the internal mechanism has high performance. The advantages can also include the cost of the device.
The only drawback is the need to connect to the compressor, whose work is heard on a dozen meters.
Now you can carefully familiarize yourself with the types of drum guides.
The mechanism of this device is equipped with an electric network engine. This type also includes rechargeable models, the charge of which is made when connected to the outlet. Electric shock wraps are often used at maintenance stations and tire. The main thing is not to put them in damp and do not work in a wet environment.
Rechargeable models are more designed to solve household tasks.
It is important to note that the electrical type device is intended for work with new fasteners, unfortunately, the rusty nuts will not be able to unscrew.
In the device of these models there is a special hydraulic cylinder, which turns pressure into the rotation of the mechanism.
Important advantage is the possibility of using a hydraulic tool in harsh conditions.
Due to the absence of an electric motor, such wrenches can be used next to flammable materials. Besides, Hydraulic wrench is not afraid of water at all, Therefore, it is used to carry out repair work in flooded premises.
Pneumatic professional devices
Pretty lungs in the weight ratio, but despite the seeming simplicity have high potential. The low price of the device will not affect the seed budget, especially if there is already a compressor in stock. Otherwise it will have to purchase separately.
These models of devices are more intended for repair and construction work of railway tracks. It is very convenient, since it is not always possible to connect to the electrical network.
In the modern world, the production of drum guides does not stand still. Every year a variety of models appear on the light, each of which has unique features. Based on manufacturers data about each individual tool and user surveys, the rating of the most popular models of wigs. The most popular electrode wrench – “ZDR SGUE-350”. This device is in high demand for owners of a hundred, and conventional motorists. The price of the instrument is very reasonable and does not affect the family budget. Its capacity is 300 nm, while electricity consumption is 350 W.
Especially nice to use this device in winter. Frozen nuts are easily unscrewed, while not feels physical exertion.
An important feature of the “bison SGUE-350” is a five-year warranty from the manufacturer, which also indicates the high quality of the device.
The most sought-after Pneumochnaya Gykovit – “Fubag IW 720 100192”. Mostly used on a hundred and tire. Simple and easy to use. The price is moderate, due to which any entrepreneur can purchase a device for the workflow. Many users praise “FUBAG IW 720 100192” for convenient adjustment of the protracted point.
Ideally works in any environment. A comfortable handle is equipped with additional vibration insulation, due to which the return tool is practically not felt. An important feature of this model lies in the power of torque that reaches 720 nm. These figures are talking about the possibility of using “FUBAG IW 720 100192” both in the passenger and cargo machine.
The most sought-after angular wrench – “Makita TL065DZ”. His compact size allows you to carry out various types of work in the most hard-to-reach places. For the convenience of the user on the case of this model installed a special lighting lamp.
Its weight is 1.5 kg, this device will easily unscrew and tighten the nuts and bolts to the size of M12.
How to choose?
For domestic use of the impact wrench, you should pay attention to the models equipped with a spindle ½ inches. It is designed to install sizes from 8 mm to 32 mm. This means that this tool will be able to unscrew the small nut in the inside of the table and, if necessary, a car bolt.
The focus when choosing the necessary model should be given to the protracted mechanism. This indicator reports the pressure of the pressure on the fastener. Too weak device will not be able to affect a rusty bolt.
Ideally, the household wrench does not possess superpowers, respectively, the torque should not exceed 160 nm. If the tool is necessary for professional work in the construction sector, it is best to pay attention to powerful devices with a torque of 700-1000 nm.
Another feature of the quality device lies in the housing. It is very important that it is made of metal, not plastic. Of course, tools with plastic cases are below, but also wear is much faster. On the other hand, a portable wrench in a plastic shell is not inferior to its fellows with a metal shell.
When choosing a pneumatic wrench it is necessary to view not only the device itself, but also its addition. For example, a compressor, without which the tool will not be able to work, it is better to choose with a rig function, that is, on wheels, which is very convenient when moving across the working area.
In the diversity of electrical actors models, the best copy is characterized by a quiet and smooth work.
Unfortunately, the underground analogues are inferior in price, but they are rather loud, and in the process of work they can drag sharply.
