What's the difference between an electric hammer and an electric pick?
Electric hammer:
Electric hammer is suitable for drilling holes in hard building materials such as concrete, masonry and so on. The electric hammer is driven by a single-phase series motor. It has the functions of 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 and porcelain. A single impact can shovel ditches and dig on concrete and brick walls. Shovel and electric hammer have high power and strong processing ability. The drilling diameter is usually between 12-50mm, and different working heads can be selected for various operations. Simple operation and high hole-forming precision. Electric hammers are generally equipped with overload protection devices, which can automatically slip when the mask is overloaded or the drill bit is stuck, and will not cause the motor to burn out electric hammers with center specifications less than 23 mm Generally, they are made into adjustable structures with hammers and only two gears. Some small and medium-sized electric hammers have the function of positive and negative rotation and can be used as electric screwdrivers. Large electric hammers not only have high drilling power, but also have a non-rotating gear.
Electric pickaxe:
Electric picks are mainly used for crushing, chiseling, digging, cutting, concrete, bricks, stones, ice cubes and so on. When assembling the pipeline. Cable laying, sanitary installation, mechanical installation, water supply and drainage facilities. Civil engineering construction such as interior decoration and port facilities construction has been widely used, which requires different forms of shovels, cutting heads and different operations. Widely used in construction and decoration industries. The difference between an electric pick and an electric hammer is that the electric pick has no rotation function, only an impact function, and the impact energy is large.
The difference between electric hammer and impact drill
If the general impact drill is 6-700W, how big the hole can be drilled depends on the size of the supporting drill. Generally, the maximum diameter is 5 cm. An impact drill works by rotation and impact. A single impact is very slight, but an impact frequency of more than 40,000 times per minute can generate a continuous force. Impact drills can be used for natural stones or concrete. An electric hammer works by rotating and knocking. The strength of a single strike is very high, and the striking frequency of 1 1,000 to 3,000 per minute can produce significant strength. Compared with impact drills, electric hammers need the least pressure to drill into hard materials, such as stones and concrete. Especially relatively hard concrete. Under normal circumstances, impact drills cannot be used as electric drills. First, it is difficult to grasp the direction of the impact drill when it is used, and it is easy to misoperate and has a large opening. Second, the drill bit is not sharp, which leads to irregular holes and burrs or cracks; Even if there is a change-over switch on it, try not to drill holes unless you use a special drill for drilling wood. However, due to the fast rotation speed of the electric drill, it is easy to make the hole black and make the bit hot, thus affecting the service life of the bit.
The electric drill only relies on the motor to drive the transmission gear to increase the rotation strength of the drill bit, so that the drill bit is in a metal state. Wood, etc. Make a hole by scraping. There are two ways for impact drill to work: adjusting knob, adjustable drill and impact drill. The impact drill uses the gears on the inner shaft to jump each other to achieve the impact effect, but the impact force is far less than that of the electric hammer. You can also drill reinforced concrete, but the effect is not good.
Electric hammers are different. It uses the motor at the bottom to drive two sets of gear structures, one for drilling and the other for driving the piston, just like the hydraulic stroke of the engine, which produces a strong impact. With the help of drilling effect, power can split stones into gold.
The electric pick is driven by the motor to swing the hammer in the form of bounce, which makes the pick have the effect of cutting the ground.
Hydraulic pump pickaxe uses the gas pressure transmitted by air compressor to drive the pump hammer in electric pickaxe to rebound, thus producing the effect of chisel hitting the ground, but electric pickaxe is only a chisel, and its pickaxe does not rotate.
Summary: Electric drills can only drill holes, impact drills can also have a slight hammering effect, while hammer drills can drill holes, and higher hammer picks can only hammer but not drill holes.
Electric drill is a kind of drilling machine powered by electricity. It is a conventional product in power tools and the most demanding power tool product. The electric drill only has a rotating mode, which is especially suitable for drilling holes in cork, metal, bricks, tiles and other materials that require little force. The electric drill only relies on the motor to drive the transmission gear to increase the rotation of the drill bit, so that the drill bit can scrape through metal, wood and other substances.
Impact drills can be used for natural stones or concrete by rotating and impacting. When the impact drill works, there is an adjusting knob at the drill chuck, which can adjust the common hand electric drill and the impact drill. The impact drill uses the gears on the inner shaft to jump each other to achieve the impact effect, and the impact force is far less than that of the electric hammer. You can also drill reinforced concrete, but the effect is not good.
Electric hammer is a kind of electric drill, which is mainly used to drill holes in concrete, floor, brick wall and stone. Specially drilling holes in walls, concrete and stones, there is also a multifunctional electric hammer, which can be used instead of ordinary electric drills and picks by adjusting it to a suitable position and matching it with a suitable drill. The electric hammer adopts two sets of gear structure driven by bottom motor. One set drives the piston to drill, and the other set drives the piston, just like the hydraulic stroke of the engine, which produces a strong impact with the drilling effect. Strength can turn stone into gold.
What do you mean by several pits in the electric hammer?
In construction engineering, the impact hammer is our most commonly used electric tool, and we often hear the sound of several pits in the hammer. What do you mean there are several pits in the impact hammer? What's the use? Come and have a look with me:
Our common impact hammers are divided into four pits and five pits:
Four pits means that the number of grooves at the drill handle of the electric hammer is four pits, that is, two steel ball grooves and two keyways, which can be applied to the four-pit electric hammer. This kind of drill is generally used on medium-sized electric hammers.
Five pits means that the number of grooves at the drill handle of the electric hammer is five pits, namely two steel ball grooves and three keyways, which can be applied to the electric hammer with five pits. This kind of drill bit is generally used on heavy impact hammers.
There are two differences between the two types of impact hammers:
The first point is that the most commonly used four pits on the market are sold in general hardware stores, which is better to match. There are some small places in the five pits where drills will not be installed.
Second, the five pits are generally used on large electric hammers, such as those over 38, because the large impact electric hammers have large torsion, and the stress structure of the five pits is relatively more reasonable. Guess you like 1. The difference between hammer drill and impact drill.
