Feed-in synchronization mechanism for large cold rolling pipe mills and synchronization method thereof

The invention relates to the field of metallurgical equipment, in particular to a feed-in synchronization mechanism for large cold rolling pipe mills, especially for large two-roller or multi-roller cold rolling pipe mills and a synchronization method thereof. The feed-in synchronization mechanism at least comprises servo motors, worm and gear mechanisms, screws, a feeding trolley and coders and is characterized in that the servo motors provide power for the two worm and gear mechanisms inside a transmission box, worms are connected to the two screws through worm gears, the two screws jointly drive the feeding trolley to move, the coders feed back the actual positions of the two screws, and a CPU controls the two screws to move synchronously through actual data. The feed-in synchronization mechanism is suitable for the large two-roller cold rolling pipe mills and the multi-roller cold rolling pipe mills, the requirements of a feed-in system for synchronism, stability and reliability can be met, the maintenanc
