After the left liner 9a and the right liner 9b are respectively clamped on the first clamp 2b and the second clamp 3b, referring to fig. 3, the first headstock 2 works, the first rotating shaft 2a drives the left liner 9a to rotate, at the same time, the X-direction linear moving module 6 drives the rotary cutter holder 5 to move to the position of the left liner 9a, then the Y-direction linear moving module 7 drives the cutting knife 5a to perform a feeding motion, and the cutting knife 5a acts on the rotating left liner 9a to rotary-cut and remove the redundant blank at the end of the left liner 9a. Referring to fig. 4, when the second spindle box 3 operates, the second spindle 3a drives the right container 9b to rotate, and at the same time, the X-direction linear moving module 6 drives the rotary cutter holder 5 to move to the position of the right container 9b, and then the Y-direction linear moving module 7 drives the cutting knife 5a to perform a feeding motion, so that the cutting knife 5a acts on the rotating right container 9b to rotary-cut and remove the excess blank at the end of the right container 9b.
Referring to fig. 2 again, after the ends of the left liner 9a and the right liner 9b are both cut and leveled, the driving module 4 drives the second spindle box 3 to move leftwards until the right liner 9b abuts against the end of the left liner 9a, then the second spindle box 3 is locked, the first spindle box 2 works, the left liner 9a and the right liner 9b generate high-speed relative rotation, and meanwhile, the driving module 4 applies a leftward thrust to the second spindle box 3. At this time, the relative rotation and axial extrusion force required by friction welding are both provided, and the left liner body 9a and the right liner body 9b are connected into a complete water heater liner 9 in a friction welding manner.
In the welding process, the left liner body 9a and the right liner body 9b are not re-clamped and still are clamping references during rotary cutting, the rotary cutting and the welding share the same reference, and the friction welding does not need to be re-clamped, so that in the welding process, the end surface of the left liner body 9a is perpendicular to the axis of the left liner body, the end surface of the right liner body 9b is perpendicular to the axis of the right liner body, and the end surface of the left liner body 9a is parallel to the end surface of the right liner body 9b.
