螺旋縫埋弧焊管生產(chǎn)線開(kāi)卷機(jī)活動(dòng)輥輪的加裝

Addition of Active Roller Device to Decoiler of SAWH Pipe Production Line

摘要: 螺旋縫埋弧焊管生產(chǎn)過(guò)程中經(jīng)常出現(xiàn)開(kāi)卷機(jī)的鏟刀油缸擺臂斷裂故障，嚴(yán)重影響了焊管機(jī)組的作業(yè)率。分析認(rèn)為：該故障產(chǎn)生的原因是當(dāng)卷板板尾脫離錐頭后，在較大的反彈力作用下板尾對(duì)鏟刀形成嚴(yán)重的沖擊而造成。提出在開(kāi)卷機(jī)處加裝活動(dòng)輥輪，以減小板尾的反彈半徑，從而避免板尾反彈時(shí)對(duì)鏟刀的沖擊，降低設(shè)備故障率，提高焊管機(jī)組作業(yè)率。

Abstract: As a failure，breaking of the scraper hydraulic cylinder swing arm is frequently encountered with during the operation of the SAWH pipe production line，which seriously affects the operation efficiency.Based on relevant analysis，it is identified that the failure is caused in the event that when the steel strip tail-end gets out of the conical head，due to a significant rebound of the tail-end，a strong impact is produced，and imposed upon the scraper， which leads to the breaking of the cylinder swing arm.Accordingly， it is proposed to get the decoiler equipped with an active roller to reduce the rebound radius of the strip tail-end so as to avoid the impact thereby upon the scraper.As a result，the failure rate of the equipment will be in turn reduced，and the operation efficiency of the pipe production line enhanced.
