Description

Technical Field

[0001] This utility model belongs to the field of scooter technology, and in particular relates to a bending device for scooter frame tubing. Background Technology

[0002] Scooters are generally divided into two-wheel drive or single-wheel drive. The most common transmission methods are hub motor and belt drive. Their main power source is lithium battery pack. Electric scooters belong to the small-wheeled vehicle category and are characterized by high speed and long range. They are composed of handlebars, wheels, pedals, etc., and are powered by batteries and driven by DC motors.

[0003] The production process of scooters requires the use of bending devices. However, the bending function of existing bending devices is not suitable for scooter frame tubing. Since scooter frame tubing requires a specific bending angle, the bending angle of the scooter frame tubing cannot be effectively guaranteed, thus failing to meet the production requirements of scooter frame tubing.

[0004] To address this issue, we provide a bending device for scooter frame tubing to solve the problems mentioned above. Utility Model Content

Lower pressure blocks are fixedly connected to both sides of the bottom of the lower pressure plate. An upper die is fixedly connected between the bottoms of the two lower pressure blocks. A tubing body is movably connected between the inner cavities of the upper and lower dies.

[0008] The present invention is further configured such that limit strips are fixedly connected to the bottom of both the front and rear sides of the hydraulic cylinder, and the bottom of the limit strips is fixedly connected to the fixing frame by bolts.
