Modern film projectors may also use an electronically controlled indexing mechanism or stepper motor, which allows for fast-forwarding the film.; Geneva wheels having the form of the driven wheel were also used in mechanical watches, but not in a drive, rather to limit the tension of the spring, such that it would operate only in the range where its elastic force is …
The eccentric shaft of the pilger mill was modeled using UNI GRAPHICS NX 7.5. The eccentric shaft was discredited using dominant elements. The 3D CAD model was imported into ANSYS CLASSICAL 11.0 in PARASOLID format; here the eccentric shaft was meshed using 3D solid elements using mapped mesh technique. Sub assembly of the eccentric …
A numerical model was established to calculate the cycle feed rate through studying the case of a cold pilger mill with the 304 stainless steel pipe. Firstly, the precise constitutive equation of 304 stainless steel was obtained through nonlinearly fitting the true stress–strain data from unidirectional tensile test. Then, the numerical method to …

The Pacific Northwest National Laboratory (PNNL) has converted its rolling mill into a lab-scale pilger mill, which required designing pilger tooling and rolls that contained multiple pilgering grooves and designing a servo-driven feed mechanism. Upon assembling and checking out the system, initial pilgering runs were completed.
This article focuses on the design and optimization of mandrel geometric shape the mandrel. In the paper use to linear profile and parabolic profile of mandrel and made of …
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 ...

The special design of the mill stand also allows MST to use rolling tools from a cold pilger mill supplied by SMS group that MST has been operating since 1956. Remscheid was where the Mannesmann brothers rolled the world's first seamless steel tube in 1886. Today, the new cold pilger mill built at this historic location represents yet another ...
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 ...
