A manual pneumatic or electrical tool designed to quickly twist or unscrewing fasteners having a thread called a wrench drum.
The shock-rotational action of the tool is used to disassemble and assemble various threaded compounds in the production of dismantling and installation work in various industries, construction, agriculture and everyday life.
The shock wrench is characterized by good mobility, has a small weight.
Manufacturers of domestic and foreign produce a fairly wide range of such a tool, characterized by performance, speed, reliability, manufacturing material, design. Modern models are characterized by a large number of diverse accessories (adapters, nozzles) that make this tool universal. Percussers of world famous firms Makita, Bosch, Hitachi were most popular and passed the test.
Device.
Impact wrench has:
frame;
engine;
reducer;
shock-rotational mechanism;
starting device;
main handle;
additional removable handle.
The working body is a replaceable tip with an internal hexagon, which is put on the fastening item. A hexagon or it is also called a key, rigidly or hingedly connected to the spindle. In the latter case, work can be carried out in hard-to-reach and constrained places.
The shock-rotational mechanism is mounted in the enclosures of the launcher and the wrench itself. The main handle has a vibration insulation and a device with which the radio interference occurs. An additional handle is used for convenience in operation and can be installed in three different positions. This allows twisting at any angle.
Main characteristics:
maximum torque, nm;
spindle rotation frequency, rpm;
frequency of impact, ud. / min.;
the weight.
Choice.
When choosing a shock wrench, you must pay attention to the following factors:
maximum torque;
engine power;
speed;
accuracy adjustment.
The higher the engine power, the maximum torque indicators and the speed of the wrench, the higher the performance.
Manufacturers produce shock wraps, operating from the electrical network 220 V or from batteries to various voltages.
