Abstract

The paper considers the problems of selection of pneumatic impact drive structure and its mathematical model. It gives the results of the PC testing of the pneumatic actuator activation process using various wiring schemes of actuating mechanism.

It is shown that one of the most efficient schemes of pneumatic impact actuator is the scheme with the built-in tank (accumulator).

The proposed mathematical model of pneumatic impact unit is universal and allows studying pneumatic actuators with the built-in tank with various schemes and control algorithms. During the research of internal transient processes in addition to pressure the temperature change in the pneumatic unit cavity while its activation was also measured. It is shown that conventional wiring scheme of impact pneumatic cylinder is accompanied by an oscillatory process, which complicates its use in hallmarking units.

Based on the PC research it is determined that pneumatic scheme with cylinder and air distributor operation synchronization allows achieving the most efficient pulse impact which in the area of movement of 0.15m provides the motion speed of the output link of about 4 m/s.

This mode is the most applicable for the hallmarking, broaching and forging processes
