Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped pipe processing, in particular to a special-shaped pipe forming die for automobiles. Background Art

[0002] Automotive internal special-shaped pipes refer to specially shaped piping systems used to transport liquids, gases or other materials inside the car. These pipes have a variety of applications in automobiles, such as the transmission of fuel, coolant, lubricating oil, brake fluid and other fluids, as well as gas and vacuum lines. These special-shaped pipes usually have special bends and shapes to adapt to the space limitations and layout requirements of the car. They need to consider a variety of factors during the design and manufacturing process, such as strength, durability, corrosion resistance, flexibility and connection methods with other components.

[0003] The urea pipe in the exhaust treatment system is an important component used to treat the exhaust gas of diesel vehicles. After the urea solution reacts with the nitrogen oxides in the exhaust gas, it can convert harmful nitrogen oxides into harmless nitrogen and water vapor, thereby reducing the nitrogen oxide content emitted by the vehicle and meeting environmental protection and emission standards. Since the shape of the special-shaped urea pipe may be more complicated, the accuracy of the equipment's precision and control ability for the forming accuracy cannot be guaranteed during the early stage of small-batch production. If the equipment is not adjusted in place or improperly operated, the material may be stretched and deformed during the bending process. Especially in the case of large bending angles or complex curves, the wall thickness of the hose may be uneven, affecting the quality and stability of the hose, resulting in reduced strength and durability of the pipe.
