Hydraulic braking device of a pneumatic actuator in the forestry and woodworking machines and devices
In the article the methods of braking of the piston of the pneumatic cylinder with hydraulic shock absorber to avoid being hit in the beginning and the end of the stroke are giving. It is established that the existing methods of braking does not provide no shock that leads to vibration, excessive noise and reduce the durability of the pneumatic actuator, in particular, manipulators. The proposed solution using a hydraulic shock absorber, a mathematical model of the braking process of the proposed method is giving. It is established that the design of a combined damper consisting of two channels with constant and variable roseliane provides the best characteristics of the braking process.
