7 types of automatic hammers: how to choose the characteristics ekspluatatsiyaf

The basis of the device with the drive works on the principle of hammer - impact force on an object or detail.

According to the input energy type hammers are divided into:

• electric;
• mechanical;
• hydraulic;
• pneumatic.

electric hammers

External energy source - the electrical network. The engine drives the rotor, which in turn acts on the striker. The latter shall transmit mechanical impulses to the percussion device.

hydraulic hammers

In this device, working fluid transmitting energy is process oil. Water make-up is carried out by the hydraulic station. Vibrational component provides an oscillator.

The liquid flow acts on the piston and the striker. Further mechanical impulse is transmitted shank percussive device.

Due to the high density and the compressibility at the working fluid, as compared with pneumatic drive, a compact article is obtained. It has a high impact strength.

Performance is 2-3 times higher than that of counterparts. In addition, the construction itself produces less noise.

Pneumatic hammers

The working fluid - compressed air. The infeed is performed by the compressor. Adjustment is made air distribution system shock. It, in turn changing the direction of air flow has the effect of periodic multidirectional pressure vector.

As a result, the piston receives a translational return movement. It creates stroke.

This instrument cluster with an external power supply included devices that convert human muscle power. The principle of operation is saved - creating a shock pulse.

Staple Moltke

Other names - construction or furniture stapler. Drive through human muscular strength or pneumatic, electric (mains or battery). The latter two are designed for industrial applications.

The device is equipped with a manually operated spring. This makes it possible to enhance the force of impact and make it to the hundredths of a second. Used to solve domestic and industrial applications. Restriction - physical capabilities.

Stapler is equipped with a mechanism to score:

• square brackets;
• U-shaped clamping elements;
• nails;
• pins.

A variation of a stapler - Staple hammer. It is a handle to which is attached Staple mechanism. The energy for driving staples - inertia impact.

Stapler has found application in the furniture industry - with the help of attached upholstery fabric. Used in construction: fixed decorative panels, electric or cable TV, "being targeted" wooden wall paneling.

Electric Stapler is equipped with a safety mechanism - in order to avoid accidental pressing on the trigger and release the bracket. Without fixing and clamping device to the base button will be disabled, hardware is out of the body.

The devices are developed and used with one type of hardware. The corresponding marking is applied to the packaging and enclosure. Issued Tacker working with 2-6 types of fasteners.

Nailers

Mechanical device for driving fasteners without the use of physical force man. The device runs on electricity or compressed air. When nailing pressurized gas supplied to the piston. Last affects the nail, pushing it into the material.

The safety mechanism is provided to protect against unintentional firing in air. Work carried out after pressing the base.

Nailers used in housing construction, assembly of large wooden structures, pallets. It is used in furniture production and finishing.

Powder-actuated tool

It is designed as a gun or a pneumatic hammer small sizes. The working body - the powder gas from the operation of the construction of the cartridge. Designed for pristrelivaniya metal dowel-nails in dense materials:

• concrete;
• brick;
• low-carbon steel.

Application is governed by state regulations. To work allowed people who have undergone special training.

jackhammers

It refers to a group of devices that have an impact on the subject of periodic variable force. The main function - impact production.

• intended for forming recesses or through holes in the partitions, foundations;
• breaks the concrete or asphalt;
• splits the overall construction details;
• loosens firm ground;
• Lots rocks and perform other functions.

As an external drive energy is used:

• fossil fuels - petrol with the installation type internal combustion engine on the hammer housing;
• air - the working fluid is compressed air supplied from the compressor;
• electricity - the power is supplied from the central network or portable generator.

Features automatic hammers

Power. For electric or petrol engine - a measure of the power plant. Compressed air - compressor capacity.

Impact strength. Work in the point of application of force or energy transmitted in a limited space object (impact tool area). With increasing rates increases the ability to work with heavy and dense materials. For example:

• up to 5 J - Removing plaster or tiles, shtroblenie a cable or pipe;
• 5-30Dzh - dismantling of masonry, concrete walls, leveling the dense base;
• 30-60 J - Treatment of frozen soil, rocks development, execution recesses in the concrete wall;
• more than 60 J - "breakers"; destruction on the ground floors, the building of reinforced concrete structures, foundations.

number of strokes. It shows the number of impacts per unit time. It characterizes the performance of the tool. A certain type of work or type of material chosen your treatment regimen.

Dimensions:

• A touch of class, up to 5 kg is used for finishing work; flexibility, ability to perform surgery in a horizontal position (perpendicular vertical planes).
• Average, 5-10 kg, used for a wide range of problems - breaching openings, analysis of the concrete base or the destruction of asphalt; due to the increased mass is constrained to operate in a horizontal plane.
• More than 10 kg - "breakers"; designed to operate in harsh environments with strong and viscous materials.

The tool is used in conjunction with devices:

• Crowbar (peak). Applicable creating indentations, holes, loosening the soil, destruction of rocks or concrete.
• Lopatka. Removes old coatings, tile, cleans the surface from sagging.
• Chisel. Used for operations in reinforced concrete, frozen soil, metal cutting.
• Rammer. Compacts the soil or soil, is used to work on the grouting cracks.

The design of the device provides a number of functions:

• soft start mode. Relevant for the drive. It allows you to smoothly increase the speed, reduce the starting load, increase the service life. Electric hammer works without jerking. Reduces the load on the hands.
• Regulation of the number of strokes. frequency adjustment is made for a specific operation. Heavy construction require maximum performance. Accurate work is performed on a minimum value.

• Fixing start button. It allows you to block the trigger, thereby freeing the operator from loading fingers.
• vibroprotection. Work mechanism causes increased vibration acting on the mechanism of the device and the operator. The use of dampers, balances, soft cushioning materials allows to reduce the load.

It is beneficial to man and the construction of the device.

• Indication of serviceability of the carbon brushes. It warns of the approaching deadline replace the motor brushes due to the wear of the conductive coating current.

Benefits

Instruments with a mechanical drive have a number of consumer qualities:

• reduction of physical load on the person;
• high productivity compared to manual labor;
• allow operations with strong dense materials, disassemble heavy construction;
• power tool, thanks to the dimensions and weight, has been successfully used to solve everyday problems;
• petrol is not dependent on external energy sources;
• pneumatic hammers are used in areas with increased fire and explosion.

How to choose the automatic hammers

When meeting with the instrument it is advisable to pay attention to a number of factors:

• Types of works performed, the volume of transactions and the intensity of exploitation of a hammer;
• An external source of energy - electricity, or hydraulic compressor station;
• the ratio of the "weight of the device - the power";
• equipment features, the number of modes of operation;
• availability of repair and service network in the village.

Despite the higher price, excellent performance, service life and warranty will help recoup the costs incurred for the purchase of necessary equipment.

Exploitation

Tool with an external drive - technically complex machine. Apply it should be exactly as prescribed. The requirements and recommendations set out in the accompanying documents: passport, instruction manual.

Violation of the rules applying to the period of the warranty period will entail the loss of free maintenance and repair.

Guarantee

Standard terms of service and set free repair by the manufacturer. Data on this are contained in the documents attached to the equipment.

malfunctions

Sophisticated failure must be addressed in the service and repair shop. It is particularly important to comply with these recommendations during the warranty period. But there are cases where the removal of the disadvantages to exercise their powers:

1. The skewed staples (nails, pins). Eliminates the bulkhead with mounting clips.
2. Damage to the wooden handle from hand tools. Repair - replacing the handles.
3. The formation of burrs on the metal striker. It is necessary to treat the surface of the grinding material.
4. The weakening of the fixation of the hammer on the handle. Replacement wedge, installing a new pen, soak in water.
5. Clogged air passage in Pnevmotehnika. Removed dirt, pieces of ice. Blown with compressed air.
6. A small number of strokes. Pneumatic - lack of air flow pressure. Electrician - low voltage network.
7. Wear carbon brushes. Replacement of new parts according to the instructions.
8. Dry moving mating parts. The reason - lack of technical oils. Troubleshooting - topping up the tank of lubricating fluid.
