Abstract
The laying head is an important equipment in a high-speed wire rod production line. The dynamic imbalance of the spinning head will cause the laying head to vibrate greatly during operation, which will seriously affect the spinning quality and the life of the laying head. In order to make the dynamic balance of the laying head meet the requirements, the critical rotational speed of the laying head rotor is firstly analyzed by using ANSYS software, and it is concluded that the laying head rotor is a rigid rotor. Then, the double-sided dynamic balance simulation of the spinning head was carried out using ADAMS software, and the correction masses required by the spinning head on the two calibration surfaces were obtained. The counterweight structures are designed according to the dynamic balance simulation results, and the thicknesses of the counterweight structures are optimized. The dynamic unbalance masses M1 and M2 of the optimized spinning head in the two calibration planes are reduced from 1.2456kg and 3.7855kg before optimization to 3.9133e-6kg and 2.9954e-6kg, and the eccentricity is reduced from 0.9966mm to 0.0002236mm, meet the design requirements.
