flange test

Overseas technique to produce pre-bending machine has been mature which have high tonnage and efficiency,but its cost is also very high.

预弯边机是大直径直缝埋弧焊管生产线的关键设备之一。

This article briefly introduced the forming process and equipment for three main forming procedure(steel plate prebending,U-ing & O-ing)of LSAW pipe production line by UOE forming method,sumed up the process parameters of forming force for three forming procedure.

简要介绍了UOE直缝埋弧焊管生产线三大主成型工序(钢板预弯边、U成型及O成型)的工艺及设备,对三大主成型工序成型压力计算公式进行了归纳和总结,并举例说明了预弯边压力机、U成型压力机和O成型压力机的主要工艺参数。

For a long time, the flat pattern development(FPD) of aircraft SMCs have been carried out by the manual computation primarily or according to experiences of workers, which keep more extra material for trimming after forming, so the efficiency is low.

由于飞机钣金件的复杂性,目前,国内还没有一个专用的飞机框肋类零件弯边展开CAD系统,通用领域的展开方法对于复杂航空钣金并不实用,而现有的针对复杂航空钣金件的展开算法也非常少。
