“…Nowadays, there are more and more kinds of shaped tube produced and manufactured by fixed plug drawing process. Xu et al proposed a newly developed plug featuring a tiny boss club structure in the sizing stage to form rectangular tube [2]. Görög et al used the fixed plug with straight groove and the fixed plug with spiral groove to form the corresponding shaped tube with inner grooves, respectively [3].…”

In the actual industrial production and manufacturing, tube drawing plays an extremely important role. In this study, a device with adjustable relative plug position is designed, the influence of relative plug position on the dimensional accuracy and the drawing force of drawn tube was investigated. The results show that different relative plug positions affect the inner and outer surface dimensions of the tube respectively. Therefore, the relative plug position can be distinguished according to the following rules in industrial production. When the position of the plug relative to the die is backward, the outer surface dimension of the drawn tube is qualified but the inner surface dimension is unqualified. When the position of the plug relative to the die is forward, the inner surface dimension of the drawn tube is qualified but the outer surface dimension is unqualified. The relative position of the plug is mainly due to the different radial force given to the tube by the plug and the die, resulting in the unqualified size of the drawn tube. When the plug is positioned backward relative to the die, the tube is subjected to the radial force of the plug first and then the radial force of the die. When the plug is positioned forward relative to the die, the tube is subjected to the radial force of the die first and then the radial force of the plug.

“…Recently, the application of the copper tube is moving forward to the refinement, high efficiency, and thin wall [1][2][3]. The newly designed die was attempted by K.Świąthowski and Xu Wujiao which made the process more stable by increasing the wall thickness reduction [4,5]. And the novel die improved the homogeneity and continuity with the inner wall of the tube.…”

In this paper, it was investigated that the defects of the bright and dark lines on the inner wall of a thin-walled copper tube by drawing with a floating plug based on analyzing the stress distribution. The experiments were conducted by employing a stereomicroscope, metallographic microscope and scanning electron microscope, respectively, meanwhile the three-dimensional finite element was applied to study the defect. It was demonstrated by the research results that the large gap between the sizing section of the plug and the outer die caused the inner wall bright and dark lines. The wall thickness was increased when the tube passed by the area without inner support which gave rise to local material uplift along the radial direction. The raised material became folds due to the effect of “leveling” when the tube pass by the conical section and the sizing sections. The fold was the essence of the bright and dark line by macroscopic scale observation. The bright and dark line was ultimately eliminated by adopting the drawing die with reasonable geometrical parameters according to experimental and simulated results.
