Abstract:

The paper presents experimental results of diameter reduction in tubes with the angle of flare alpha=30(0). Tube diameter reduction was performed on the WPM-120 cold profile eccentric rolling machine. In the investigations, AISI MT 1020 (ASTM A513) steel tubes with the relative ratio s(0)/D=0.09 were used. The appropriate values of the eccentric and feed were chosen for the experiment. The coefficient of necking for the samples was K=D/d=1.46 (where d - smallest diameter in reducing tubes after rolling, D - initial outer tube diameter). The evaluation of the quality of the samples obtained in the experiment was based on the measurements of cylindricity and the wall thickness distribution in the longitudinal section of reducing tubes. The measurements of cylindricity were taken with the ZEISS PRISMO navigator, a coordinate measuring machine. The results obtained in the experiment might be used as guidelines to develop a technological process for manufacturing such type of reducing tubes with the WPM cold rolling method. They could also be helpful while applying the method to industrial practice.
