With the rapid economic development, people's living standards are getting higher and higher. In the era of the development of electrical appliances, science and technology products to make people more and more efficient to complete the work. In the daily home decoration commonly used hardware electric tools are mainly electric drill, hammer, and so on, them is directly related to the quality level of the home, electric drill and electric hammer have what distinction? Which is good in the end? Below we bring you knowledge of electric hammer drill.
First, the meaning of
1, drill
Drilling machine using electricity as power. Is an electric tool in the conventional products, but also the largest demand for power tools products. Drill working principle is electromagnetic rotary or reciprocating electromagnetic small capacity motor rotor makes the magnetic field cutting acting operation, operation device driven by a transmission mechanism, drives the gear to increase bit of power, thus allowing the drill bit scraping the surface of the object, the better the perforated objects.
2, hammer
With a pneumatic hammer
Electric rotary hammer drill with safety clutch for mechanism. Hammer principle is driving mechanism drives the drill bit to do rotary motion and a direction vertical to head reciprocating hammer hammer motion. The hammer is driven by the transmission mechanism
A piston in a cylinder of reciprocating air and cylinder air pressure, periodic change drive cylinder in the hit the top of the hammer back and forth to hit a brick, if we use a hammer to knock brick, named hammer!
Two, difference
1, the volume is not the same size. The volume ratio of a large hammer drill, electric hammer because inside cylinder, connecting rod, piston and other important parts. The drill can drill drilling wood, metal, plastic and other materials.
2, the component is not the same. Drill which only the motor rotor and stator and the gears are biting and some revolutions, hammer is not the same, should be called "the hammer" so it has impact force, can drill concrete, stone and other hard materials.
3, open holes are different. The hammer is the movement of the piston and compressed air percussion bit, need not make much effort, the hole in the concrete, brick, stone and other hard materials open 6--100mm hammer in
The material is provided with high efficiency, but it can not be opened on the metal. Drill is not impact the human pressure on the metal, opening holes in wood and other material, diameter 6-50mm. advantage is small vibration, open hole with high accuracy, price
Not high.
4, with the drill bit is not the same. The hammer is inlaid with alloy drill, drill bit is ordinary.
5, the damage is different. Hammer and hammer can open holes in concrete structures, with all two piston motor function.
Hammer for large diameter above 30MM. High efficiency, large aperture, long drilling depth. But the vibration is big, and the surrounding structures have a certain degree of damage. For reinforced concrete structures, can not be passed, due to the scope of work, can not be too close to the building.
Impact drill is suitable for 25MM small diameter and short drilling depth, etc.. Such as the installation of expansion bolts, etc.. The destruction of the surrounding structures is very small.
Three, household choice
Actually for families, electric drills impact more suitable for home users, although hammer to hit the wall can also be installed on the connecting rod chuck can also be a blacksmith, but hammer on chuck blacksmith accuracy effect no impact drill well, because the electric hammer
Play for wall, while the impact drill appears to function more widely, if you are home dry small live to wall drill a small hole hanging something such as, the impact of drilling is the best choice for home users.
Customers if you choose a dual-purpose electric hammer (hammer and drill function), hit the wall operation, only need to directly to the drill bit is inserted into the electric hammer can be used, if used in the electric drill function, such as blacksmith play wood must to use connecting rod
And drill chuck. In use process, please note that usually use electric drill mounted on the connection rod and a clamping head, gear must be placed in drill stalls, do not hang in the shift impact position, or pick rod can be easily knocked deformation, resulting in connecting rod stuck the consequences.
