为了解决冷轧扭机的振动问题,研制了一种新型预应力轧机。这种轧机不仅刚度高,而且具有消振和自我安全保护性能。对称设计可实现孔型自动对中的精确调整。具有投资低,见效快的优点。本文着重介绍了轧机的产生和理论研究成果。这种新轧机命名为短变应力线消振轧机。 In order to solve the vibration problem of the cold-rolling twisting machine, a new type of pre-stressing mill has been developed. This mill not only has high rigidity, but also has damping and self-safety protection. Symmetrical design allows precise adjustment of the hole type automatic alignment. With low investment, quick advantage. This article focuses on the mill production and theoretical research. This new mill is named short-stress line damping mill.
