Abstract
A percussion mechanism of a hand-held power tool includes a reciprocating percussion piston (1) displaceable under the action of a pneumatic spring (5) to apply blows to an end surface of a working tool (8), which is received in a chuck (7) of the power tool, directly or via an anvil (6), with the percussion piston (1) and/or the anvil (6), when the anvil is used, being formed of a non-ferromagnetic material.
Claims16
A percussion mechanism for a hand-held power tool, comprising a reciprocating percussion piston (1) for applying blows to an end surface of a working tool (8) received in a chuck (7) of the power tool;
- and a pneumatic spring (5) for displacing the percussion piston (1),
- wherein the percussion piston (1) is formed as a one-piece part of a non-magnetic material.
A percussion mechanism for a hand-held power tool, comprising a one-piece reciprocating percussion piston (1) for generating blows;
- an anvil (b) located in front of the percussion piston (1) in an operational direction of the power tool for transmitting blows to an end surface of a working tool (8) received in a chuck (7) of the power tool;
- and a pneumatic spring (5) for displacing the percussion piston (1),
- wherein at least one of the percussion piston (1) and the anvil (6) is formed of a non-ferromagnetic material.
A method of manufacturing of a percussion mechanism of a hand-held tool and including a reciprocating percussion piston displaceable under an action of a pneumatic spring for applying blows to an end surface of a working tool received in a chuck of the hand-held tool, the method comprising the step of forming the percussion piston, which is formed as a one-piece part, of a non-ferromagnetic material.
