由日本中田制作所新开发的制管成型机(FLEXIBLE PIPE FORMING)简称FF成型。在管的粗轧工序中采用了独特的边缘弯曲变形和多辊成型方式,通过一套“共用”轧辊,不需换辊,只要对“共用”轧辊进行位置和角度的调整,就可以生产出不同规格(例如3″～8″)、不同厚度(例如8″管厚度可由3～9.5mm)、不同材质的优质焊接管。根据计算机(CAD)计算出来的轧辊位置,采用液压调整和数码显示,操作人员按此数字显示,可极方便地对轧辊的位置进行调整,且可以准确地实
Nakata by Japan’s newly developed tube making machine (FLEXIBLE PIPE FORMING) referred to as FF molding. In the tube roughing process using a unique edge bending deformation and multi-roll forming methods, through a set of “common” roll, no roll change, as long as the “common” roll position and angle adjustment, you can produce Different specifications (eg 3 “~ 8”), different thickness (eg 3 “- 9.5mm for 8” tube thickness), high quality welded pipe of different material. Calculated roller position according to computer (CAD), hydraulic adjustment and digital display , The operator according to this figure shows that the roller position can be very easily adjusted, and can accurately
