HFW焊管管端特殊坡口的生產(chǎn)

Processing Techniques for Special End-beveling of HFW Pipe

摘要: 現(xiàn)有的管端倒棱設(shè)備無法滿足HFW焊管37.5°特殊角度外坡口的倒棱要求。針對這一問題，提出以外坡口角刀桿上的選定點為基準(zhǔn)點，改變刀片主切削刃的空間位置，使其與空間垂線的夾角由30°變?yōu)?7.5°加以解決。經(jīng)過生產(chǎn)現(xiàn)場的批量試車驗證，該改進設(shè)計方案行之有效，可以滿足對HFW管端特殊角坡口形狀的倒棱要求。

Abstract: To solve the problem that the pipe-end chamfering facilities as being used at present by the company are not capable of meeting the requirement for processing the special 37.5° bevel angle of the HFW pipe， a technological measure is proposed， i. e.， taking the point as selected on the bar of the outer bevel cutter as the reference point so as to change the space position of the cutter blade's major cutting edge to turn the angle between it and the spacious perpendicular line from the original 30° into 37.5°. The result of the workshop trail massive production has proved that the modification design proposal as implemented is so effective that the requirement for processing special end bevel profile of the HFW pipe is satisfied.
