常见的弯曲工艺有三种:V 形弯曲、U 形弯曲和压料弯曲(即带压料垫的弯曲)。现在有一种称为“旋转弯曲”的新工艺可能成为更加常用的工艺方法。旋转弯曲的主要优点是它比其它弯曲方法所需要的弯曲力小。旋转弯曲的工作过程和压料弯曲比较相似,但压料弯曲需要两种力:压料力和弯曲力。压料弯曲存在的问题是在弯曲时,压料垫下面的材料受到弯曲力后有向上隆起的趋向。解决的办法只有增加压紧力,然而假如材料厚度超过6.4毫米和长度超过127毫米时,那末压紧力就高达10吨,通常由氮、液 There are three common bending processes: V-Bend, U-Bend, and Bender Bend (ie, Bending with Mats). There is now a new process called “spin-bending” that may become the more common process. The main advantage of rotating bending is that it requires less bending force than other bending methods. Rotational bending work and binder bending is relatively similar, but the material bending requires two kinds of force: pressure and bending force. The problem with the binder bending is that when bent, the material under the binder pad tends to bulge upward after being bent. The solution is only to increase the compaction force, however, if the material thickness exceeds 6.4 mm and the length exceeds 127 mm, the compaction force will be as high as 10 tons, usually from nitrogen,
