The cross wedge rolling mill is a new technology for forming shaft parts. Compared with other processes, it has the characteristics of high production efficiency and low production cost. It is widely used in the production of parts such as automobile,trolley,motorcycle,engine and hardware tools.
Since 1989 our team of professionals has been helping our current North American customers to develop new markets and coordinate selling and servicing their products in the Former Soviet Union.
A new crosswedge rolling method which uses only one flat wedge and two shaped rolls is described in this paper. This new forming method was called wedgerolls rolling (WRR).

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.
Cross Wedge Rolling Machines CrossWedge Rolling Machines are used for forming axisymmetric parts by altering their cross section. Three baseline types of crosswedge rolling machines are available that use different rolling methods: cold, warm and hot crosswedge rolling.
In 2005, Zhao et al. [22] used the Deform3D software to model a multiwedge cross rolling (MWCR) process, wherein a part is formed by more than one pair of wedges simultaneously, which results in ...
Nov 03, 2014· In largescale and mass production, the technology of crosswedge 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 crosswedge rolling (CWR) include: manufacturing of shafts, axles, fingers, pins for aircraft, automobiles, railroad, tractors ...

Aug 08, 2017· CrossWedge Rolling Mill The authors have developed a method of crosswedge rolling (CWR) railway axles, the specification of which is given in Table 1. This technology has yielded the highest productivity – up to 120 axles per hour (less allowances and tolerances) – and achieves minimal metal consumption that helps minimize labor input ...
Cross wedge rolling (CWR) is an advanced metal forming technique for producing preforms (for press forging) or finishedformed stepped axes and shafts. This process is based on the use of wedgeshaped tools mounted either on the rolls or on flat (or concave) rolling mill plates.

Oct 04, 2019· The crosswedge rolling (CWR) technique was conceived at the end of the 19th century and was believed to be ahead of its time. CWR is considered to be the most costeffective technology for largescale, highvolume commercial production. The essence of the process is that the billet experiences elastoplastic spinning between two wedge tools that are mounted on plates and move in parallel ...
Cold Cross Wedge Rolling is used mainly for the manufacture of axisymmetric parts, allowing the molding pressure at normal temperatures and compressions. Cold rolling advantages: improvement of strength properties as a result of strain hardening, high dimensional accuracy, almost the final shape and high quality of the surface of the part.
Crosswedge rolling is a warm forging process for plastic deformation of cylindrical forms into axissymmetrical parts. In a standard hammer forging process, a steel workpiece is heated and formed to a desired shape by impact. In Eaton''s new process, the preforms are heated to 2,200°F and rolled to form the transmission shafts.
