Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 小さな加工治具を用いて小さな駆動力、小さ な騒音で管端に拡径加工し得るようにすることを目的と する。 【構成】 被加工管(P)の管端内径内に入り込む所定 形状の加工治具(25)を先端に有する主軸(23) と、該主軸を管径方向に可動に保持する本体ハウジング (11)と、該本体ハウジングに固設され、加工治具の 反対側から管端外周部を押さえてその反力を受けるカウ ンタ部材(81、101A、101B)と、上記本体ハ ウジングに設けられ主軸を管径方向に駆動する駆動機構 (41、43)と、上記主軸の径方向移動量を規制する ストッパ手段(61、75)とを有し、管端内に挿入し た加工治具を管径方向に移動させることにより管端を拡 径する。 (57) [Summary] [Purpose] The objective is to enable diameter expansion processing on the pipe end with a small driving force and a small noise using a small processing jig. [Structure] A spindle (23) having a processing jig (25) of a predetermined shape which is inserted into the inner diameter of a pipe end of a pipe to be processed (P) A main body housing (11) for movably holding the main shaft in the pipe radial direction; and a counter member fixed to the main body housing for pressing the outer peripheral portion of the pipe end from the opposite side of the processing jig and receiving the reaction force ( 81, 101A, 101B), a drive mechanism (41, 43) provided in the main body housing for driving the spindle in the pipe radial direction, and stopper means (61, 75) for regulating the radial movement amount of the spindle. The diameter of the pipe end is expanded by moving the processing jig, which is included in the pipe end, in the pipe radial direction.
