    The working principle of electric hammer introduces the correct use method and notice of electric hammer

    Introduction of electric hammer working principle

    Electric hammer is a type of drill, mainly used in concrete, floor, brick walls and stone. There are also multi-function electric hammer, adjusted to the appropriate position with the appropriate bit can be used instead of ordinary electric drill, electric pick use.

    The electric hammer is driven by the transmission mechanism piston in a cylinder reciprocating compressed air, the cylinder in the air pressure cycle driving the cylinder in the cylinder reciprocating down the top of the brick, as if we hammer with a hammer.

    Electric hammer, in addition to the same rotation as a drill, the function of the front and rear movement, usually includes the drill function, some electric hammer also called the impact drill. Electric hammer suitable for large diameter of more than 30 mm.

    Advantages: the advantages are high efficiency, large aperture and long drilling depth.

    Disadvantages: the disadvantage is the large vibration, which has a certain damage to the surrounding structure.

    Working principle: the principle of electric hammer is the reciprocating hammer movement perpendicular to the head while driving the drill bit to rotate. The electric hammer is driven by the transmission mechanism piston in a cylinder reciprocating compressed air, the cylinder in the air pressure cycle of the cylinder reciprocating the top of the brick, as if we use a hammer to hit bricks, guming

    The correct use and attention of electric hammer

    Personal protection when using electric hammer

    1. operators shall wear protective glasses to protect their eyes, and wear protective masks when facing upward operation.

    2. always plug good earplugs in long-term operation to reduce the effect of noise.

    3. the bit is in the hot state after long-term operation, and should pay attention to burn the skin.

    4. the handle should be used in the operation, and the hands should be manipulated to sprain the arm when Stall.

    5. standing on a ladder or work on a height shall be done well with falling measures. the ladder shall be supported by ground personnel.

    Matters needing attention before electric hammer operation

    1. verify that the power supply of the site is consistent with the dianchuimingpai. Is there a leakage protector?

    2. the drill bit and holder shall be adapted and properly installed.

    3. when installing the wall, ceiling and floor, you should first confirm whether the cable or pipeline is buried.

    4. when working on high altitude, pay full attention to the safety of the following objects and pedestrians, and set warning signs if necessary.

    5. verify that the electric hammer switch is cut off and if the power switch is switched on, the electric tool will turn suddenly when the plug is inserted into the power outlet, which may lead to danger of injury.

     6. if the operating site is far away from the power supply, the extension line when the cable shall use the capacity enough to install the qualified extension cable. The extension line lanru shall be elevated or done to prevent the cable from being crushed by roller crush.

    The correct operation method of electric hammer

    1." with impact drilling" operation

    ( 1 ) push the working mode knob to the zhuankong position.

    ( 2 ) place the bit in the position of drilling hole, and then turn off the switch trigger. Push the drill only slightly, let the chip can freely discharge, do not need to press.

    2." chipping and crushing" operation

    ( 1 ) pull the working mode knob to the" danchuiji" position.

    ( 2 ) using the weight of the drill rig, do not need to press.

    3." drilling" operations

    ( 1 ) pull the working mode knob to the" drilling" ( not hammer ) position.

    ( 2 ) place the drill bit in the position of drilling hole, and then turn off the switch trigger. Light push can.

    Iv. checking the drill bit

    The use of a slow or curved bit, will cause the motor to overheat and reduce the operating efficiency, therefore, if such conditions are found, replace immediately.

    Five fastening screws examination

    Due to the impact of electric hammer operation, easy to make the dianchuiji installation screws loose, the fastening should be checked frequently, if found the screw loose, should be Again immediately, otherwise the electric hammer failure.

    Checking carbon brushes

    The carbon brush on the motor is a consumable, once the abrasiveness exceeds the limit, the motor will fail, therefore the wear of the carbon brush should be replaced immediately, and the carbon brush must be kept clean.

    Vii. protection of grounding wire

    The protection of grounding wire is an important measure to protect personal safety, so the class appliance ( metal shell ) should often check its enclosure should have good grounding.

    Viii. inspection of dust hood

    The prevent is designed to prevent dustiness immersion in the internal mechanism, if the prevent internal grinding, should be replaced immediately.
