Cold pilger technologyTube and pipe making
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 of other processes.
Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses.
Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (4) which is secured in, and rotated by, a thrust block. Two dies (2) "form" the tubular stock in the same way that a rolling pin rolls out pastry. These two dies are mounted in a reciprocating saddle (3). Their drive pinions mesh with two stationary racks. That's how the dies rotate back and forth in synchronization with the reciprocating saddle. The saddle, in turn, is moved back and forth by a crank drive in the same way as a piston in the engine of a motor car.
SMS group cold pilger mills achieve large reductions in both diameter and wall thickness. Simultaneously, they significantly reduce eccentricity due to the homogenization of the material flow during forming. This creates the required microstructures in the material.
There is a huge demand for the automation of complete cold pilger mills and integrated individual machines. That’s another SMS group specialty.
So, whatever you want, from individual sensors, through drive and control technology, right up to planning and implementation of computer-aided information and control systems: SMS group supplies complete solutions.
Remote access to the machine control system for fault analysis is possible only after authentication by the customer. Direct analysis and evaluation of the operating parameters are performed online by the SMS Service employees. They can easily identify defects and malfunctions and initiate measures for fault elimination. Remote access also allows the system software to be updated. Naturally, the installation of the necessary hardware and software for the remote access is already included in the remote service.
