In this paper,a high-speed seamless steel tube cold drawing unit with the characteristics of verti-cal lifting feeding,multi-mode capillary traversing distribution,horizontal core threading of mandrel and dou-ble-station rotating mandrel table is realized. The unit realizes the automatic operation of bulk materials,lifting and feeding,lower drawing,blanking and other processes in the production process of cold drawn tubes;Up to five diameters achievable Ф28～Ф63.5mm,wall thickness 3.5～10mm,length 8～26m carbon steel and low alloy steel pipe drawn at the same time;The maximum nominal drawing force of the unit is 60t,and the maximum drawing speed is 50m/min. The equipment has improved the design and manufacturing level of the domestic cold-drawn pipe production unit and the production technology level of the enterprise,and has far-reaching significance for promoting the development of technical equipment in China's steel pipe industry.
