Title:
FRICTION-TYPE PIPE DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/049122
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a friction-type pipe driving device in which, even when a pipe is rotationally driven for a long time, transfer in the length direction is minimal, and additional position correction is thus not required. In order to achieve the above purpose, the present invention is characterized by a friction-type pipe driving device that rotates a pipe by friction for pipe processing, comprising: a base that supports a structure of the entire device; a driving source comprising a rotation shaft which is mounted on the base and rotated by a separately supplied power source; a plurality of driving shafts which are coupled to the base via bearings and arranged in parallel, and on which a pipe for processing is seated so as to contact the driving shafts; and a transmission part that transmits power of the driving source to the plurality of driving shafts, wherein the driving shafts comprise a plurality of external grooves formed at regular intervals at a portion at which the pipe contacts.
