Description
technical field [0001] The invention relates to a cutter for cutting a through hole of a cylinder body of a breaking hammer, and belongs to the field of cylinder body processing of a breaking hammer. Background technique [0002] Breaking hammer is a kind of hydraulic energy as power to drive the piston inside the upper cylinder of the hydraulic cylinder to reciprocate, and hammer the drill rod through the piston to transmit energy to the drill rod, and the energy on the drill rod is then It is an important construction machinery that is absorbed by the hit object and crushed by the hit object. It is mainly used for crushing, demolition, and excavation of hard layers in construction. It is usually installed on excavators, loaders or power stations. It has the advantages of strong impact, convenient use, good maneuverability and high efficiency. With the development of hydraulic technology, hydraulic breakers are more and more widely used in all walks of life in society. Fro...
