摘要： A pipe facing machine performs cutting, bevelling and deburring operations on an end of a pipe that is stationarily held in the same position during all three operations. A tool head that rotates about the pipe carries knives for performing the various operations. Initially, two diametrically opposed cutting knives are advanced in a radially inward direction to engage the pipe while the tool head is rotating to cut it at a predetermined location. Thereafter, as the cutting knives are being withdrawn, a bevelling knife and a deburring knife are advanced radially inward to a point where the bevelling knife provides a desired bevel on the cut edge of the pipe. During the radially inward motion of the deburring knife, it is maintained at an axially displaced position where it does not engage the pipe. Once it is located radially within the interior of the pipe, it is axially moved to a position where it is in alignment with the cut, bevelled edge of the pipe, and it is then withdrawn in a radially outward direction simultaneously with the bevelling knife, to remove the burr provided on the interior edge of the pipe by the bevelling knife.

摘要： Method and means for preforming the long edges of steel plate prior to manufacture into pipe by the U-O Process or the like by utilizing plate of a width exceeding that required for pipe of a given diameter by an amount at each edge having an excess at least equal to the width of the pipe. Roll-forming the plate to use the excess width thereof as a lever arm to obtain a bend at the bitter edges of the pipe (edges required for pipe) of a radius required for the pipe and thereafter shearing the plate to form the bitter edges, followed by bevelling and polishing the bitter edges, and further roll-forming the edge area to complete the preform thereof.
