The impact drill relies on rotation and impact to work.A single impact is very mild, but the impact frequency of more than 40,000 times per minute can generate continuous force.Can be used for natural stones or concrete.When the impact drill work, there are regulatory knobs at the drill head. You can adjust the two ways: ordinary flashlight drill and impact drill.However, the impact drill uses the gear on the inner shaft to achieve the impact effect, but the impact is far less than the electric hammer.It is not suitable for drilling steel bars.
Impact drill repair
There is nothing to say in the first step, just to remove the impact drill.Remove the screws and open the lid. This kind of work DIYER can operate even the first brother.But it is a bit troublesome to remove the steeringrs.There is a bayonet in the steering device, which must be removed from the shell to remove it.Rotate the steering gear, align the bayonet, you can easily remove the steward.The steer is also blocked by the bearing, and then the carbon top can be opened.This disassembles the steeringrs.The ring structure that leaves the motor is the "steering device" mentioned above.If you look closely, you can know what the reason is.
Impact drill principle
Principles of impact drilling: impact movement is driven by the motor through gear transmission, driving the crank and connecting rods, so that the pressure piston piston moves in the impact piston cylinder, and the compressive gas is promoted to the piston tank hammer head.The end, the tools are flushed forward.The rotation movement is a general gear transmission, which drives the ends of the hexagonal tool by the motor by the gear transmission to generate the rotation motion.When the overload slipped, the clutch played a safe protection role.
Impact drill model
Giant QCZ-1 pneumatic impact drill: It is a multifunctional impact drill. It is not only highly powerful, but also without sparks. In high gas and mine, it can especially reflect its safety.TSB1300 new Bosch impact drill: The design of the fuselage is very compact, even in a small space, it can be used freely.Bosch GSB16Rectn shock drill: You can select the speed by setting.The configuration has a rotating carbon brush frame, and its positive and negative work efficiency is the same.
How to use the impact drill
There are newly bought the key to get the key. If there is no key, use a long -shaped metal object to use a hammer to hit it with a hammer at the quasi -pit.EssenceThe switch on the top of the electric drill top is two gears for impact and no impact. Generally, the pattern is generally a hammer with impact (for hitting the wall).The small knob on the switch at the point is to adjust the speed, and the handle switch can also adjust the forward and reverse.
Impact drill price
Generally speaking, the price of high -profile brands is more expensive: Bosch (German technology), Hitachi (Japanese technology), Dewei (American technology), Makita (Japanese technology), the price is generally about four or five hundred yuan.Mid -range brands: Hundreds, the price is generally around two or three hundred yuan.Masterpieces: Anhai Europe, five yuan, the price is generally about 1,200 yuan.
What brand of shock drill is good
1. Bosch (began in 1886, Germany, world brand, global electric tool leader spinning business, industry influence brand, Bosch Electric Tools (China) Co., Ltd.) 2. Dewei (belonging to one of the largest electrician tool producersBest Corporation, a global manufacturer of high -quality tools, Stanley Best Corporation, USA) 3. Mai Tai Bao (in Germany in 1924, one of the famous professional electric tool manufacturers in Germany, large multinational enterprises, world brands, Mai TaibaoElectric Tools (China) Co., Ltd.)
The difference between impact drill and electric hammer
The electric hammer is generally impacted by the oil pressure piston, that is, you can hammer mixed dirt, pass through the wall, etc., that is, it is quite fierce.Compared with the function of impacting the electric drill, the weight is slightly lighter than the electric hammer, and there is no electric hammer.
