pneumatic percussion hammer

Abstract

The invention relates to a pneumatic knocking hammer. The pneumatic knocking hammer comprises an end cover (1), a pressing plate (2), a permanent magnet (3), a hammer body (4), an impact hammer (5), a spring (6) and a separating plate (7); the end cover (1) is connected to the hammer body (4) through a bolt, and the pressing plate (2) and the separating plate (7) are synchronously fixed on the hammer body (4); the permanent magnet (3) is embedded into the lower part of the pressing plate (2) and fixed through the separating plate (7). Compared with the prior art, the pneumatic knocking hammer has the advantages that the permanent magnet cannot be separated from the embedding and fixing part; in addition, the radiating effect of the permanent magnet can be improved; the magnetism cannot be reduced as the temperature raises; the service life can be prolonged.

Description

technical field [0001] The invention relates to a percussion hammer, in particular to a pneumatic percussion hammer. Background technique [0002] Pneumatic percussion hammer uses compressed air to make the impact hammer strike the pipeline or silo, so that the powder attached, bonded or blocked in this part will be impacted and loosened. [0003] The customary pneumatic percussion hammer such as figure 1 As shown, it consists of an end cover 1, a pressure plate 2, a permanent magnet 3, an impact hammer 5, a spring 6 and a hammer body 4, wherein the end cover 1 is fixed on the hammer body 4 by bolts, and the impact hammer 5 is arranged inside the hammer body 4. The spring 6 is set on the impact hammer 5, and the permanent magnet 3 is embedded in the impact hammer 5 and placed under the pressure plate 2. Since the impact hammer 5 is struck at a certain frequency, the permanent magnet 3 embedded in the impact hammer is very easy. Break away from the impact hammer, causing th...

The spring 6 is set on the impact hammer 5, and the permanent magnet 3 is embedded in the impact hammer 5 and placed under the pressure plate 2. Since the impact hammer 5 is struck at a certain frequency, the permanent magnet 3 embedded in the impact hammer is very easy. Breaking away from the impact hammer, causing the pneumatic percussion hammer to fail

And because the magnetic force of the permanent magnet will weaken when the temperature exceeds 80°C, which will affect the knocking effect
