The working principle of hammer and saw

Hammer for large diameter such as 30MM or more. The advantage is high efficiency, hammer in addition to the same as the rotation of the drill there are functions before and after the usual hammer including electric drill function. Hammer and impact drill can be opened in concrete structures. Both have a piston motion function. Large aperture, drilling

Depth is long. The disadvantage is the vibration of the surrounding structures have a certain degree of damage. Hammer principle is the drive mechanism to drive the drill to do the same time, there is a direction perpendicular to the rotor of the reciprocating hammer movement. The hammer is driven by the drive mechanism in a cylinder

Reciprocating compressed air, the cylinder air pressure cycle changes lead the hammer in the cylinder to blow the top of the rotor, as if I used a hammer knocked turned. Impact drill for 25mm or so small diameter and short penetration conditions. Such as expansion bolts. The destruction of the surrounding structures is very small.

Used to cut wood, stone, steel and other cutting tools, electric saws as a driving force. The edge of a sharp tooth. Break up fixed and portable, saw blade is generally made of tool steel, a round bar and chain, and so on. The current drives the small motor, and then the motor passes through some of the mechanisms that connect the drive so that the blades rotate and work.

Operation rules for saws

First, check the operation before the saw a variety of performance is good, safety devices are complete and meet the operational safety requirements.

Second, check the saw blade shall not have cracks, chainsaw all kinds of screws should be tightened.

Third, the operation to wear protective glasses, standing on the side of the saw blade, prohibit standing on the same line with the saw blade, the arm may not cross the blade.

Fourth, the feed must be close to the mountain, not too much force, the case of hard to slow push. Picking material to be saw blade 15cm. Do not pull hard by hand.

5, short narrow material application push stick processing, picking the use of shaver hook, more than the radius of the saw blade of wood, prohibit the saw.

6, electric saw maintenance should be power maintenance operations.

7, for safety reasons, after use must be removed saw blade.

Before using the operator, remember to check whether the performance of the saw is good, the safety device is complete and meet the operational safety requirements and other operating procedures to prevent accidents
