Rolling process for producing 70 mm diameter balls using a flat-wedge reversing mill: (1)-(5) - stages of rolling Fig. 11. Variations in the tangential force during rolling The results of measurement made with an infrared camera (Fig. 12) reveal that the temperature on the surface of the balls is 950 °C.
in accordance with the above concept, a flat-wedge rolling mill was designed and constructed. The results demonstrate that the machine can be used to produce balls from heads of scrap railway rails. Keywords: forgings of balls, rolling, cross-wedge rolling mill 1. Introduction Steel balls used as grinding media in various types of ball
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.

Nov 03, 2014· In large-scale and mass production, the technology of cross-wedge rolling (CWR) of axisymmetric parts made of ductile metals and alloys is virtually unequaled in its economic efficiency. The only exception is parts produced by cold stamping. The application domains of cross-wedge rolling (CWR) include: manufacturing of shafts, axles, fingers, pins for aircraft, automobiles, railroad, tractors ...
The method of cross-wedge rolling allows producing articles from billets that have round, hexahedral or square section and also from tube. As a result of cross-wedge rolling initial profile is transformed into round profile. By cross-wedge rolling it is possible to obtain the articles, which contain round section elements such as cylinders, cones and spheres, rectangular section such as flats ...
Apr 06, 2016· Cross wedge rolling (CWR) is a flashless preforming step which enables forging companies to save material and energy. In the research project CoVaForm, IPH developed a CWR machine that is designed ...
Highlights The new method of balls forming by means of helical wedge rolling is presented in this paper. Obtained solution has many advantages in comparison to traditional balls forming method applied in industry. The scope of research consists of numerical simulations FEM and experimental tests.
Cross wedge rolling (CWR) is an advanced metal forming technique for producing preforms (for press forging) or finished-formed stepped axes and shafts. This process is based on the use of wedge-shaped tools mounted either on the rolls or on flat (or concave) rolling mill plates.
Experimental and numerical analysis of helical-wedge rolling process for producing steel balls Article in International Journal of Machine Tools and Manufacture 67:1–7 · April 2013 with 181 Reads
Jun 12, 2018· The rolling mill is provided with wedge tools with the shape identical to that of the tools used in the numerical simulation. Fig. 18 Flat-wedge rolling mill ( a ) available at Lublin University of Technology and lower tool set ( b ) for manufacturing ball pins with two tools
Cross-wedge rolling is a process conducted mainly in hot forming conditions. Warm forming is a compromise between hot and cold forming. This paper presents the results of a comparative analysis of warm and hot rolling of ball-shaped pins.
Rolling processes are used in all areas of forming technology, both in hot forging and cold forming, and of course in sheet metal forming. There is a multitude of rolling processes. Some are named here: flat rolling, profile rolling, tube rolling, roll forming, forge rolling, cross-wedge rolling, wire rolling, and cross-row rolling.
