PURPOSE: To realize a mass balance and torque balance of a cold pilger mill with a simple constitution. CONSTITUTION: A transmission gear formed of cranks 7 and balance masses is divided into two transmission gear parts which are arranged in a mirror image to a plane which vertically intersects a roil axis 10. The transmission gear parts are arranged …

For new fast-neutron sodium-cooled Generation IV nuclear reactors, the candidate cladding materials for the very strong burn-up are ferritic and martensitic oxide dispersion strengthened grades. Classically, the cladding tube is cold formed by a sequence of cold pilger milling passes with intermediate heat treatments. This process acts upon …

A cold pilger mill including a rolling mechanism for intermittently rolling a tubular material over a mandrel to a reduced-diameter pipe. A detector (74) is associated with the rolling mechanism for detecting the rolling phase in the rolling mechanism. A feeding mechanism (42) for feeding the material in the axial direction and a turning mechanism (64, 68, 70) …

Crank mechanism of cold pilger mill and saddle speed. Fig. 3 shows a schematic view of the crank mechanism of a cold pilger mill. The pair of roll dies is installed in the saddle housing. The rotation of the drive motor is transmitted to induce the reciprocating motion of the saddle via the connecting rod by a crank shaft mechanism. …

Cold pilgering is a longitudinal cold-rolling process that reduces the diameter and wall thickness of metal tube in one process step. Depending on the material, the …

mechanical FE model of the cold pilgering process is developed. The Johnson-Cook model is used to describe the flow stress accounting for temperature, strain rate and strain path dependency. 2 BACKGROUND The estimation of roll separation force is required for pilger mill design andto determine limits for tube dimensions or process parameters.

The invention relates to a cold pilger rolling mill with a reciprocating roll stand, which is coupled to the crank pin of a crank via a push rod and whose inertial mass can be partially compensated for by counterweights. In this case, the transmission formed from crank drives and counterweights is divided into two transmission parts arranged in mirror image of a …

Depending on the material, the cold pilger process achieves cross-sectional reductions of more than 90 percent in a single working cycle. Figure 1 shows the principle of the cold pilger process. As mentioned above, the part of billet (hot-, cold rolled or extruded etc. tube) 1 that equals to feeding volume, gets into moving zone of working cage ...
