Tel.: +421-48-645-4172. E-mail address: [email protected] Abstract The paper deals with optimization of hollow sinking process of seamless steel tube E235. Specifically, the last two sequences are merged into one drawing pass by one tool. Saving one hollow sinking operation will save rebuilding on the drawing bench, tube handling and increase ...
In a hot pilger mill for seamless tubes of 508 mm maximum diameter, fatigue failure occured of the shaft on which the motor rotor, the flywheel (9 m diameter) and one hub of the coupling were seated.
chapter will discuss design details specific to. the pellet mill die and the rolls. In Figure 4-1, we see a typical pellet mill die. The particular die shown is a clamp-on type and shows a keyway cut into the backside of the die. This type of die is driven by a die-driving key mounted into the front face of the quill flange, or die-driving rim ...
Tube drawing is a process to size a tube by shrinking a large diameter tube into a smaller one, by drawing the tube through a die. This process produces high-quality tubing with precise dimensions, good surface finish, and the added strength of cold working. For this reason this process is established for many materials, namely metalworking but ...

9. Design Retention. CNC machines are capable of saving prototype designs for future production. Design retention helps with efficiency and ensures the finished products are identical, regardless of operator changes. For example, it doesn't matter who starts the machine because the designs are pre-loaded and it can create uniform products.

New design for the pilger mill was proposed in [7]. The rolling stand is stationary and the rolled tube is placed on a slide and placed between the rollers (Fig. 2). The hydraulically driven slide is put into to-and-fro motion, and the rollers only rotate. In extreme slide positions, like in the classical process, the tube further rotated and ...
Tube and Pipe Production. The cold pilger process is a common method of finishing seamless stainless steel hollows. Many aspects of the pilgering process influence machine productivity and finished tube quality. This article discusses an analysis done on two different tool die designs and their effects on tube quality and machine productivity.
