Impact drills work by rotation and impact. Impact drills work by rotation and impact. The single impact is very slight, but more than 40,000 impacts per minute can produce continuous forces. Can be used for natural stone or concrete. When the impact drill is working, there are adjustment knobs at the drill chuck, adjustable common hand drill and impact drill. But the impact drill uses the gears on the inner shaft to beat each other to achieve the impact effect, but the impact force is far less than that of the electric hammer. It is not suitable for drilling reinforced concrete.
Introduction
Impact drill: The impact mechanism of the impact drill has two kinds of dog teeth and ball type. Ball-type impact drill consists of moving plate, fixed plate, steel ball and other components. The moving plate is connected with the main shaft through threads and has 12 steel balls; the fixed plate is fixed on the housing by pins, and has 4 steel balls. Under the action of the thrust, 12 steel balls roll along 4 steel balls. The carbide drill bit can generate a rotary impact motion and can drill holes in brittle materials such as bricks, blocks, and concrete. Take off the nail, so that the plate with the drive plate rotation, no impact, can be used for ordinary electric drill.
Use description
It is mainly used for impact drilling of concrete floors, walls, bricks, stones, wood boards and multi-layer materials; it can also be drilled and tapped on wood, metal, ceramics and plastics and equipped with electronic speed adjustment equipment. As a forward/reverse function.
The impact drill motor voltage has two different voltages: 0V-230V and 0V-115V. It controls the clutch of the micro switch, and obtains different speeds of the motor at different speeds. It is equipped with forward and reverse steering control mechanisms, elastic screws and tapping.
Precautions
The impact drill can not be used for the electric drill under normal circumstances: First, it is difficult to grasp the direction of the impact drill in use, and it is prone to misoperation, and the opening is too large;
The second is that the drill bit is not sharp, so that the hole opened is not neat, there is a burr or crack;
Third, even if there is a switch above, try not to drill, unless you use a dedicated drill bit, but because the drill speed is very fast, it is easy to make the hole black and make the drill heat, thus affecting the use of the drill life.
Fc 207 Bearing,the most commonly used type of mounted units, are designed to provide shaft support where the mounting surface is parallel to the shaft axis. The bolt holes are usually slotted for adjustment during mounting. Pillow blocks are supplied in a variety of configurations. Pressed steel pillow block bearings are also available for light-duty applications.
