designs. Particularly the software has been instrumental in ideating modifications to address repeated failures encountered in a shaft analyzing and optimizing design. The genesis of the project lies in repeated failures encountered in eccentric shaft of Main Drive Gear Box (MDGB) of a pilger mill. The

The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.

The design parameter of Pilger mill roll is the surface shape of the roll under compressive stress and the amount of feeding rate. For the present analyses the feeding am ount was set to be 5mm. Three surface profiles of the roll were testified using linear, quadratic and cosine curves in the interval size ...

The optimum design of a die shape for Pilger mill process was carried out using FEM analyses considering various processing factors. The important design parameters of the Pilger mill machine are feed rate and profile of the grooved die. Optimum design procedure was conducted in order to investigate effects on forming load and the deformed shape of a material depending on the die …

The conversion of the rolling mill to a pilger mill consisted of removing the mechanical linkages that connected the gear motors to the roll dies. The pilger mill system was designed to use index-able servo motors that are connected to the large drive rolls directly. This design allows for more flexibility in the degree and speed of die rotation.

Our cold pilger mills use a special cold forming process which is both cost-efficient and indispensable for many applications. It involves a large number of forming steps to improve roundness, stress homogeneity, and surface roughness of the tubes. You can even apply our cold pilger mills to produce difficult materials beyond the capabilities ...
