1.Introduction for U Rib assembly machine:
This machine is mainly used to press the U-rib firmly onto the base plate, forcing the U-rib to align with the assembly line of the base plate, eliminating the gap at the contact point between the U-rib and the base plate, and performing manual positioning and spot welding at the joint of 6 U-ribs and the base plate.
This machine is composed of a walking frame, a walking track, an overall U-rib pressing module, a hydraulic system, a manual welding system, etc.
