Study On The Analysis And Testing Of Shew Piercer's Force Parameters

The seamless steel tube has important action in the country's economy construction. It has been used in many field such as oil exploitation,drilling and spaceflight. The product quality is nearly correlative with the key facility——piercer. The pierer's performance impacts on the seamless steel tube's quality and stardard straightly. And now, the research of rolling force character is not sufficient at home and abroad. Because of the piercer's conformation is complex, then leading to working state and the analysis of suffering force are complex. So the rolling pressure and rolling moment of academic counting is far from the pratical testing.In order to increase the seamless steel tube's quality and depress investing cost, it only depends on examination test research. Herein the paper analyzed the shew rolling piercer's rolling pressure and rolling moment at the rolling. Then the paper researched the ?350 piercer rolling pressure and rolling wrest moment through test on-line. So the research mostly carried on hereinafter several aspect:The paper used the two shew roller piercer as the example because it employed widly. Then researched the piercer's configuration character and working process, analyzed the suffering force about important parts of piercer at roling. It educed the key parameter that affected on the piercer working state and product quality. These are the rolling pressure and rolling wrest moment.The paper has carried on test on-line and researched the ?350 piercer's rolling pressure and rolling moment, basing on a great deal of practical testing data, using the statistics theory and comparing to the academic counting result and the practical. Then amended the academic counting formula in allusion to the others offered. And bringed forward the relatively logical experience formula for counting rolling force. The paper offered relatively formula for piercer's designing and fabrication in the future.The paper researched and put forward the test system project about ?350 piercer's rolling pressure and rolling moment . Educed preferably and reliability testing result through practical test. The test system project and such material test means are universality and advancement by all means. It has biggish guidance meaning to the piercer academic design and production. It may use for reference to similar test.
