Impact Process Identification for Impact Cylinder Piston

Zbrowski A.

Acta Mechanica et Automatica

2012

Vol. 6, no. 2

88-92

The phenomenon of the tool rebound from the object processed, that can be noticed particularly in the case of impact marking, has a negative influence on the quality of the processing of moving objects, which is a result of the blur effect caused by the shift of the object processed at the time of its retraction. The objective of the study was to determine the influence of both the capacity of the chamber of the accumulator and the working pressure on the characteristics of the phenomenon of the piston rebound from the obstacle that can be noticed after it hits a hard fender for the very first time. The article present the results of research consisting in the analysis of the rebound phenomenon for impact cylinder pistons. The tests were carried out for cylinders whose structure allowed for the change in the capacity of the accumulator chamber. Cylinders with the pistons of 40 and 100 mm in diameter and supplied by 4 and 6 bar pressure were subject to tests that were undertaken at the test stand equipped with Phantom V310 high speed digital camera.

Metodę bezkontaktowych pomiarów położenia tłoczyska z wykorzystaniem triangulacji laserowej opracowano na potrzeby eksperymentalnego wyznaczania charakterystyk siłownika udarowego. Przeprowadzono badania siłowników udarowych z nastawianą objętością komory. Przedstawiono wyniki analizy charakterystyk siłowników udarowych uzyskanych na drodze eksperymentalnej.

The non-contact measurement method based on laser triangulation was developed for the need to calculate stroke characteristics of impact cylinders. The tests of impact cylinders with an adjusting chamber were performed. The analysis results of experimentally obtained characteristics were presented.
