Abstract:In order to improve the stability of the gauge of rotary flat-cylinder，the development of rotary flat bars and the requirement of rotary flat bars for wide card are introduced.By comparing the structure of aluminum alloy rotary flat bars of card at home and abroad，a kind of adjustable rotary flat bars with preset bending tension and aluminum alloy heel and toe block of rotary flat are developed.The test results show that the new patent aluminum alloy flat bars，by adding transverse bars and carbon fiber adjusting rod in the cavity，can increase the shear resistance and flexural strength in runing process，and solve the problems such as large deformation，large flat clothing difference，difficult to adjust the gauge，and easy to cause card clothing contact of aluminum alloy rotary flat bars.The heel and toe block of aluminum alloy rotary flat made by powder metallurgy with special wear-resisting material can improve the poor wear resistance and short service life of common heel and toe section.
Key Words:card；rotary flat；wide；rotary flat bars；flat clothing difference；gauge；carbon fiber；heel and toe block；heel and toe difference
