在液压成形工艺期间,通过挤压坯料形成支撑凸缘,以提供双厚度凸缘。
The support flanges are formed by pinching the blank during the hydroforming process to provide a double thickness flange.
下轮改为凸缘轮,彻底改变了原双链轮成本高,易脱链的缺陷。
Next to the wheel flange, completely changed the original double chain cost is high, easy to take off the chain of defects.
