    • The present invention relates to a drawing machine having a device for inspecting an inner peripheral surface of a drawn tube, and more particularly, to a drawing machine having a device for inspecting an inner peripheral surface of a drawn tube, which includes dies having a drawing hole through which the drawn tube is passed; a drawing plug located at the center of the drawing hole and having a first accommodating portion formed to pass therethrough in a drawing direction thereof so as to determine the inner diameter of the drawn tube; and a photographing part disposed in the first accommodating portion to photograph at least one of the image and video of the inner peripheral surface of the drawn tube. According to the present invention, defects on the inner peripheral surface of the drawn tube can be detected during the drawing process to control the defect factors and reduce the loss of the material, thus achieving improvement in the quality of the drawn tube, the reduction of the material loss, the shortening of the drawing process time and increasing the productivity in the whole drawing process.
    • 本发明涉及一种具有用于检查拉制管的内周面的装置的拉丝机,更具体地,涉及一种具有用于检查拉管的内周面的装置的拉丝机,该拉丝机包括具有拉丝的模具 拉出管通过的孔; 位于所述引导孔的中心的拉拔塞,具有形成为沿其拉出方向通过的第一容纳部,以确定所述拉制管的内径; 以及设置在所述第一容纳部分中以拍摄所述拉制管的内周表面的图像和视频中的至少一个的拍摄部分。 根据本发明,在牵引过程中可以检测拉伸管的内周面上的缺陷,以控制缺陷因素并减少材料损失,从而实现拉管质量的提高, 材料损失,缩短绘图过程时间,提高整个绘图过程中的生产率。
