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.
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.
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.
Using the method of crosswedge rolling it is possible to manufacture articles from structural steels, separate grades of tool and highalloy steels, aluminium, brass, copper, titanium. Metal utilization ratio during crosswedge rolling is 7097%, which, as a rule, is .

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.
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.
2. Essence of cross wedge rolling with upsetting In cross wedge rolling with upsetting (Fig. 2), the wedges affect the material from the frontal surface towards the middle part of the billet. Initially, a ringshaped wedge groove is rolled, then – owing to the action of the side surfaces of

May 19, 2017· D46type Highefficiency Precision Rolling Mill Crosswedge rolling means that cylindrical billet experiences continuous local deformation .
Cross wedge rolling has proven to be an economical and reproducible means of producing preforms for forging operations. The process control is far superior to traditional manual drawing operations. DEFORM can be used to optimize the rolled shape in the blocker or finished forging dies.
D46 series double stick cross wedge rolling mill . 1. Cross wedge rolling is a new hotting processing produces steps uranium forgings, and rolls the steps uranium with revolvers expecially.. rolled pieces achieve the final shape of products almost, and the material utilization is higher. When used to blank for the die forging, it can distributes the blank accuratly.
Crosswedge rolling mill used in experimental testing. Figure 3 presents one of the wedge tools securing the preform rolling pr ocess. The forming wedge. is characterized by the angles.
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 ...
