Problems solved by technology
[0002] At present, most of the cold drawing devices for the production of seamless steel pipes use short mandrel single-mode pipe drawing, and short mandrel single-mode pipe drawing requires multiple passes of pipe drawing to obtain finished pipes with qualified dimensions. The production cycle is long, energy consumption is large, and production costs are high. , and the drawing resistance is large, the tool life is low, and the lubrication effect is poor

Disclosed is an ultrasonic vibration compound die tube drawing device which is mainly composed of a drawing stand, a compound die, an ultrasonic vibration generator, a core bar, a seamless steel pipe to be drawn, a core print, and the like. The device is characterized in that: the compound die is fixedly inlaid on the drawing stand, the ultrasonic vibration generator is installed on one end of the core bar, the core print is installed on the other end of the core bar, the core print is placed in the inner wall of the seamless steel pipe to be drawn, the core print is located on a small-sized diameter reducing and sizing band portion of a compound die inner bore, a head end of the seamless steel pipe to be drawn is clamped by a drawing clamp arranged on a drawing mill after passing through the compound die inner bore, the seamless steel pipe to be drawn moves forward under a pulling effect of the drawing mill through the drawing clamper, the seamless steel pipe to be drawn first passes through a large-sized diameter reducing and sizing band of the compound die inner bore to perform the first diameter reducing and sizing, and then the seamless steel pipe to be drawn passes through the small-sized diameter reducing and sizing band of the compound die inner bore to perform the second diameter reducing and sizing.
Description
Technical field [0001] The invention relates to an ultrasonic vibration composite die pipe pulling device, which belongs to the technical field of metal rolling. Background technique [0002] At present, most of the cold drawing devices for the production of seamless steel pipes use short mandrel single-mode pipe drawing, and short mandrel single-mode pipe drawing requires multiple passes of pipe drawing to obtain finished pipes with qualified dimensions. The production cycle is long, energy consumption is large, and production costs are high. , and the drawing resistance is large, the tool life is low, and the lubrication effect is poor. Contents of the invention [0003] In order to solve the above-mentioned drawbacks of the short mandrel single-mode extubation device, the present invention provides an ultrasonic vibration composite die extubation device, the drawing force of the device is reduced by about 10% compared with the short mandrel single-mode extubation device...
