三辊式型材卷弯机上使用的轧辊一般可分为标准(通用)轧辊与特殊轧辊.标准(通用)轧辊用来卷弯角钢、扁钢、方钢和T形钢等;特殊轧辊是专用的,用于卷弯管材、圆钢、槽钢和工字钢等.现在的型材卷弯机上新配备的轧辊,都需预制若干个大小垫片,用以调定轧辊的辊缝,以便与型材的厚度相对应.所以每卷弯一种规格的型材,都要拆卸轧辊,换装新的垫片,再紧固轧辊.这种轧辊结构使生产准备时间长,费时费料又费力,效益较差.
Rollers used on the three-roll profile bending machine are generally divided into standard (general) rolls and special rolls. The standard (universal) roll is used for winding, flat, square and T-shaped steels; For pipe bending, round bar, channel steel and I-beam, etc. The newly equipped rolls on the current profile bending machines require a number of prefabricated shims for setting the roll gap so that So the thickness of the profile corresponds to each roll of a profile of the profile, have to remove the roll, dress up a new gasket, and then tighten the roll. This roll structure to make the production of a long time, time-consuming and laborious, cost-effective Poor.
