What is the difference between electric hammer

The electric pickaxe allows the motor to drive the flicking mound to bounce, so that the pickhead has the effect of chiseling the ground. The pump hammer in the electric pickaxe bounces back and forth, which produces the effect of the pickaxe hitting the ground, but the electric pickaxe only chisels, and its pickhead does not rotate. The electric hammer is an electric rotary hammer drill with a safety clutch attached with a pneumatic hammering mechanism. The electric hammer uses the principle of piston movement. Compressed gas impacts the drill bit. It does not require much effort by hand. It can open 6-100 mm holes in hard materials such as concrete, brick, stone, etc. It is higher, but it cannot open holes in the metal. What is the difference between electric hammer and electric pick Electric hammer The electric hammer is suitable for drilling on hard construction materials such as concrete and masonry. The electric hammer is powered by a single-phase series excitation motor. With rotating belt impact, single rotation and single function, single rotation and rotating belt impact are suitable for drilling holes in brittle materials such as concrete, rock, masonry, porcelain, etc. Single impact can shovel trenches on concrete and brick walls Digging, shoveling, large hammer power, strong processing capacity, drilling diameter is usually between 12-50mm, different working heads can be selected for multiple operations. The operation is simple, the hole forming precision is high, and the electric hammer generally has an overload protection device, which can automatically slip when the mask is overloaded or the drill bit is stuck, without causing the motor to burn out the central specification electric hammer below 23MM. And the adjustable structure that only rotates two gears, some small and medium-sized electric hammers have the function of positive and negative rotation, and can be used as an electric screwdriver. The impact has no rotating gear, and the working head of the electric pick can be used as an electric pick. Electric pick The electric pickaxe is mainly used for assembling pipes by crushing, chiseling, digging, cutting, concrete, brick, stone, ice, etc. Laying cables, sanitary equipment placement, mechanical installation, water supply and drainage facilities. Interior decoration, port facility construction and other civil engineering constructions have been widely used. According to the need, there is a lack of money in different forms of shoveling, cutting heads, and different operations. Widely used in construction and decoration industry. The difference between the electric pick and the electric hammer is that the electric pick has no rotation function, only an impact function, and the impact energy is large. How to use the electric pickaxe correctly 1. Installation or disassembly of the hammer head Before installing or removing the hammerhead, be sure to turn off the power switch of the electric pick and unplug the power plug from the power socket. Installation and disassembly of the four-pit hammer head: fully pull down the adjusting ring, and then insert the hammer head into the hammer head clamp, and insert it all the way. At this time, if you loosen the adjusting ring, the ring will automatically push back to the original position to fix the hammer head. After installation, be sure to try to pull the hammer head out to confirm whether it is fixed in place. When disassembling the hammer head, the adjustment ring can be pulled down completely, and then the hammer head can be pulled out. Installation and disassembly of the hexagonal hammer head: For example, a 65-type electric pick, pull the lock pin outward and rotate 180 at the same time. Then, the flat side of the drill bit faces the lock pin, inserts into the hexagonal hole, and then rotates the lock pin 180 at the same time. , Clamp the drill bit. When disassembling the drill, pull the lock pin outward and rotate 180 at the same time. , And then pull out the drill. The 38-type electric pick is equipped with a clamp iron, and one end of the clamp iron is pulled apart before the hammer head can be installed or removed. 2. Operation of power switch Before inserting the power plug of the electric pick, be sure to confirm whether the power switch can be pulled freely and whether it can be returned to the 'OFF' position when the power switch is released. To start, just pull the power switch; release the power switch, you can shut down. For continuous operation, you can pull the power switch, and then press the lock button. To shut down from the locked position, pull the power switch to the end and then release it. 3. Use of electric picks Install the hammer head in place, use the weight of the machine, and firmly hold the electric pick with both hands to effectively control the recoil movement. To start work at an appropriate speed, excessive force will reduce efficiency. 4. Check the hammer head Using a blunt hammer head will make the motor work abnormally and reduce the operating efficiency. Therefore, if the hammer head is obviously worn, it should be replaced with a new one immediately, or processed quickly. 5. Grinding chisels Only a sharp chisel can be used to achieve good results, so it is necessary to grind the chisel on time to prolong the service life and ensure good operation results. To grind the chisel, you can use a grinding wheel (such as a diamond grinding wheel), and continue to water while grinding, reasonably grasp the grinding size, to ensure that the peak of the chisel does not appear tempered, otherwise the hardness of the chisel will be affected. 6. Check the mounting screws Always check whether the mounting screws are tight. If the screws are loose, they should be retightened immediately. Otherwise, serious accidents may occur. 7. Extension cable If the work site is far away from the power supply, use an extension cable with a sufficient current carrying capacity (the cross-sectional area of ??the wire must be large enough), and it should be as short as possible without connectors. Damaged cables should be repaired or replaced in time. In winter, anti-freeze cables should be used, and sockets should be drop-resistant sockets. 8. Ground Class I electric pickaxes must be grounded during use to prevent the operator from being shocked. The electric pick is equipped with a three-core wire and a grounding pin to fit a normal grounding socket. The green-yellow wire in the cable is the ground wire. Never connect the green-yellow wire to the phase wire. 9. Other The electric pick is a tool for intermittent work. When the work is overheated, the operation should be suspended to allow the machine to cool naturally before continuing operation. It is recommended to cool for 5-10 minutes after continuous operation every 10-15 minutes. When using, beware of hidden electric wires, gas pipes and water pipes, you can use a metal detector to check the work area and then work. When operating the electric pick in a low-temperature working environment, the oil picks up and the electric pick sometimes does not start to impact even if the motor rotates. When the electric pick is used again at low temperature or after a long period of non-use, it must be preheated after a period of time (about 5 minutes of operation) before the electric pick can work at full power. The working head can be used to briefly hit the ground to shorten the warm-up time.
