Abstract
A double-line cold pilger mill comprises a frame, a carrier, a driving mechanism and a crank connecting rod mechanism. The driving mechanism drives the crank connecting rod mechanism to move. The carrier arranged at the end of the frame comprises a V-shaped groove, a support frame, a first handpiece and a second handpiece. The V-shaped groove is supported by the support frame. The crank connecting rod mechanism comprises a first eccentric wheel, a second eccentric wheel, a first connecting rod and a second connecting rod. The first eccentric wheel and the second eccentric wheel are rotationally connected to the frame through a first rotary shaft. One end of the first connecting rod is rotationally connected to the end face of the first eccentric wheel, and the other end of the first connecting rod is hinged to the first handpiece. One end of the second connecting rod is rotationally connected to the end face of the second eccentric wheel, and the other end of the second connecting rod is hinged to the second handpiece. An angle AOB ranges from 80 degrees to 100 degrees. The second handpiece is in a deceleration phase while the first handpiece is in an acceleration phase, and vice versa. The inertia force generated during moving of the first handpiece and the second handpiece on the frame is partially offset, so that energy is greatly saved.
