摘要:
以某种空腹焊接异形截面冷弯型钢为例，分析研究了闭口冷弯型钢常用的“圆变方”和“直接成方”成型工艺的优缺点及出现的问题。结合两种成型工艺的优点，提出了一种新的冷弯复合成型工艺，阐述了其工艺变形方案，按照产品要求设计了工艺参数，确定了成型和定径过程。使用该复合成型工艺生产既可实现异型管形状尺寸要求，又可满足弯角R很小（R为1.5倍壁厚）而无开裂现象的要求。
Abstract:
Taking a kind of welding process on cold-formed section steel with abnormity section as example, it analyzed and studied advantages and disadvantages of welding process commonly used in closed-profile cold-formed section steel, which are “become square from round” and “directly turn into square pipe”, as well as problems occurred in two welding processes. Combined with advantages of two welding processes, it put forward a new kind of compounded forming process, explained its technology deformation project, designed process parameters according to product requirements, and determined forming and sizing procedures. This kind of welding process not only can meet shape and dimension requirements of special pipe, but also make the radius of R angle remain very small(R=1.5 times thickness) without cracking.
