The automobile radiator in the engine water cooling system is composed of a water inlet chamber, a water outlet chamber, main fins and a core body. The coolant flows inside the core body, and air passes outside the core body. The hot coolant cools down due to heat dissipation to the air, and the cold air warms up because it absorbs the heat dissipated by the coolant. The core assembly includes a core body, main fins and a guard plate. The core body is a combination body in which heat dissipation tubes and heat dissipation fins are arranged at intervals. Guard plates are arranged on the left and right sides of the core body, and main fins are arranged on the upper and lower sides of the core body.

[0003] At present, the heat dissipation tubes of automobile radiator cores are usually S-shaped, and the heat dissipation tubes need to be bent to a certain extent during the production process. The bending process of the existing heat dissipation tubes is mainly carried out manually with the aid of jigs, resulting in low production efficiency, a large amount of manpower input, and the general device cannot bend heat dissipation tubes of different sizes when bending heat dissipation tubes, and a large amount of time is required to replace the bending device suitable for the size, making the bending process very cumbersome and the production efficiency low. In view of the above defects, it is necessary to design a bending device for automobile radiators. Content of the Utility Model
