Description

Technical Field

[0001] The utility model belongs to the technical field of heavy truck beam forming, and more specifically, particularly relates to a pipe bending forming tool suitable for a truck battery replacement base beam. Background Art

[0002] Heavy trucks have a large load capacity, high fuel consumption and huge emissions, so the need for electrification is more urgent. For the electrification solution of heavy trucks, battery replacement is the first choice rather than fast charging. This is because the battery capacity of heavy trucks is too large. If fast charging is used as a solution, the charging power cannot be supported. In this case, the battery replacement solution for container trucks came into being. Due to the limitations of some vehicle models, the car frame is curved, so the battery replacement base beam fixed to the car frame must also have the same bending angle. The material specification of the battery replacement base beam is generally 100*150*8mm square tube, which is large in size and cannot be formed or processed by normal pipe bending machines. The existing processing method has large grooves, which will rebound after bending and forming, and the size cannot be guaranteed. When the angle deviation between the car frame and the battery replacement base beam is too large, the installation bolts will be stuck, affecting operation safety. Utility Model Content
