Air beveling machines for piping accessories excellent in rotation and running stability

摘要

The present invention relates to an air chamfering machine for piping parts with excellent rotational stability, and particularly relates to a new concept of technology for chamfering while smoothly supporting various piping parts (elbows, T-type pipes, etc.) that were difficult to be chamfered due to a short straight section. . When improving various piping parts such as elbows and T-shaped pipes having a short straight section, the chamfering machine disclosed in the related art cannot be closely supported inside and outside, and thus cannot be used for purposes of improving piping parts. The present invention is a method for eliminating this problem, by using a thin outer diameter grounding roller and an inner diameter grounding roller, the pipe parts are smoothly chamfered while being grounded to the inner and outer diameters of the points adjacent to the end of the straight section of the pipe parts. Of course, as the pair of roller support arms are opened or closed according to the forward/reverse rotation operation of the spacer, a pair of outer diameter ground rollers are devised to ensure that the outer diameter of the pipe can be accurately grounded to the outer diameter regardless of the diameter of the pipe. It is characterized by.
