High Speed Continuous Pilger Mill Advantages: Low maintenance cost Easy operation(One person can operate two equipment) Extremely high yield (improved by 60% to 150%) Low break-down rate (servo structure) Product with high precision Characteristics : 1)The high-speed equipment of type 1 uses a multi-shaft balance structure, and therefore the number of rolling is improved by 40% -50% by comparing with that of middle speed. Due to the increase of the continuous feeding and rolling device, the yield is totally increased by at least 60% by comparing with that of the middle-speed shutdown servo equipment. 2)The high-speed equipment of type 2 uses a ‘galaxy’ balance structure, by which the rack can be driven without the connection rod, the inertia force generated in the rolling process can be neutralized further, and the number of rolling and yield can be improved significantly. By taking the type 2 equipment with the high speed of 15 for example, the speed, compared with that of the middle-speed shutdown servo equipment, is improved by 128%, and the yield is totally increased by 148% due to the configuration of the continuous feeding and rolling device. 3)The equipment of type 2 uses the feeding mode of single screw rod, so as to reduce the torque required in the work of the servo motor, and improve the response speed of the carriage. 4)All the high-speed and continuous feeding cold pilgering mills controlled by using 6-7 units of servo motor, and therefore the work of each moving part is more flexible. 5)The equipment is provided with a sliding cover, by which the roller can be replaced quickly, the time consumption is reduced, and the yield is improved. 6)The stroke of the saddles is increased, the long-journey rolling is carried out by annular ring type roller, the rotation angle of the roller is changeable, the groove working section is lengthened, the length of deformation zone is increased, and therefore the uniformity of metal deformation in the rolling process is increased, the feed amount can be increased, and the quality of the finished pipe can be improved. 7)The rotary feed system is controlled with German Rexroth AC servo, wherein the feed amount is accurate, reliable and stepless adjustable, the deviation of feed amount is not more than 2%, the size of the rotation angle can be adjusted, the billet will be rotated and fed for two times in the same rolling process, and therefore the distribution of rolling force is even, the axial force is reduced significantly, the high-precision pipe with small deviation of the outer diameter and wall thickness can be obtained, and the yield is high. 8)Compared with side feeding, the rolling mill, which uses end feeding mode, reduces mandrel-removing device; moreover, the position of the mandrel in the deformation zone is accurate, length of mill is shortened, the mode is suitable for the rolling of long billet, and the working efficiency of the rolling mill is improved. 9)Function of loading, unloading, feeding and other procedures are controlled with PLC program,, and therefore the degree of automation is high. 10)The rolling pressure of machine is reduced by using a curve type core bar, and therefore the deformation of the billet metal is even and reasonable. 11)The main gears are provided with hardened tooth grinding process, by which the transmission is smooth, and the noise is low. 12)The main shaft and important gear are made of high-strength alloy steel. 13)The inner surface of the billet used is lubricated to improve the inner surface quality of the pipe, while prolonging the service life of the core bar. 14)The rolling machine uses annular ring type roller, curve type mandrel, as well as the rolling mode of dual rotation and dual feed, and therefore the correction ability to the billet of which the wall thickness is uneven is relatively strong. 15)The equipment has a mandrel fracture detection device, by which the equipment will be automatically stopped in case of the fracture of mandrel, and therefore the equipment can be protected well. 16)A number of patented technologies are applied to the equipment, such as floating type brake, and hydraulic locking nut of the rack.
