The clamping roller feeding mechanism 203 can then clamp the workpiece 8 to move forwards towards the servo feeding device 3, and when the front end of the workpiece 8 contacts with the material blocking positioning mechanism 309 of the servo feeding device 3, the operation is stopped, the initial position of the front end of the workpiece 8 is determined, and the workpiece 8 can be conveniently conveyed to the pipe cutting machine 4 according to the required coupling length; the servo feeding device 3 clamps a workpiece 8 according to the cutting length set by an NC system and feeds the workpiece 8 into a main shaft 4011 of the pipe cutting machine 4 in a fixed length mode, the pipe cutting machine 4 starts a main clamping mechanism 405 to clamp and position the part of the workpiece 8 positioned at one end of a cutting mechanism 401, a floating hydraulic chuck 305 on the servo feeding device 3 is used as an auxiliary clamping mechanism to clamp and fix the part of the workpiece 8 positioned at the other end of the cutting mechanism 401, and then the cutting mechanism 401 cuts off the workpiece 8; after the pipe cutting machine 4 finishes the first coupling cutting cycle, the hydraulic drive manipulator 308 retracts to clamp the next section of workpiece 8 again, the workpiece is continuously fed to the length required by the next coupling, and meanwhile, the last coupling formed after cutting is pushed by the length of one coupling and enters the coupling conveying device 5; the workpiece 8 is continuously conveyed by the hydraulic driving manipulator 308, the workpiece 8 is continuously cut by the pipe cutting machine 4, and the former coupling is continuously pushed into the coupling conveying device 5 after being cut off and is directly connected to the last coupling; the coupling moves to 5 afterbody material blocking departments of coupling conveyor and stops, the coupling is stirred the upset by kicking mechanism 9 and is followed to roll and send material way 13 and get into skinning machine 6 and carry out the excircle turning processing, its back is followed the material way and is got into marking machine 7, carry out automatic pneumatics or laser coding (plain code and two-dimensional code), carry out automatic sign indicating number discernment of sweeping after the coding, data upload the storage, sweep the sign indicating number back, work piece transfer robot 11 is with the coupling unloading to in the charging basket 1202, after the charging basket 1202 count is full, carousel 1201 rotates and drives the transposition of charging basket 1202, empty charging basket 1202 continues to connect the material, the dolly transports full charging basket 1202, then transports empty AGV charging basket 1202. In the process, manual intervention is reduced through smooth connection among the devices, so that the processing efficiency is improved, and the labor force is reduced.
