矢印Ｖ）。When manufacturing long tubes such as superheater tubes for boilers by welding pipe materials against each other, it is necessary to groove both ends of the pipe materials. Beveling at both ends was performed using two beveling machines as shown in Fig. The beveling heads are installed coaxially and facing each other, and the pipe material P to be processed is fed between them to perform beveling.The processing steps are 1.
, In order to carry the pipe material P to the middle part of the left and right opening-bevel cutting rays S% ], ], 'arrow I), first move the pipe material P to the left side (arrow ■) and use the left beveling machine 1. Bevel the left end of the pipe material P. Next, move the pipe t1'P to the right side (arrow ■), use the right beveling machine 1' to bevel the right end of the pipe P, and after processing, return the pipe P to the intermediate position. (arrow ['/), 'iT material P is being carried out (
Arrow V).

Unfortunately, if the length of the tube material is too long, the gap between the two end tipping machines must be adjusted.

Rather than increasing the size of the entire device, each bevel (length)
A separate drive source is required for each, which has the drawback of high cost.

First, the pipe material P is carried in from the left side coaxially with the cutting tool holder 4 of the processing head 3 (arrow a), and the carried pipe material P is
It comes into contact with the left-hand stopper device 6 and is stopped at a fixed position, and is gripped and fixed by the left-hand clamper device 7. Next, the left cutting tool holder 4 of the processing head 3 moves to the control P end, and the cutting tool 5 cuts a bevel at the right end of the pipe material P. After processing, the cranometer 4' device 7 is released, and the pipe material P is moved backward (arrow 1), further lowered (arrow C), passes through the workpiece conveyance groove 2a (arrow d), and is moved to the ped. Sent to the opposite side of 2.

Arrow f). The carried-in pipe material P is brought into contact with the right-hand cranking device 6', stopped at a fixed position, and gripped and fixed by the right-hand cranking device 7', as in the case of processing the right end described above. Then, the right cutting tool holder 4' of the processing head 3 moves to the end of the pipe material P, and a bevel is cut at the left end of the pipe material P using the cutting tool 5'.
加工後はクランパ装置７′が解除され、管材Ｐは右方に
搬出される（矢印ｇ）。After processing, the clamper device 7' is released and the tube material P is carried out to the right (arrow g).
