specific examples of pipe end forming machines applied in automotive chassis structures

Chassis Oil Pipes: The chassis oil pipes of a certain sedan model are made of T3 red copper pipes (φ5mm×1mm), and both ends need to be formed into a double-flanged structure to ensure leak-proof sealing after locking with self-collapsing nuts. Equipped with corresponding dies, pipe end forming machines can complete process steps such as cutting, straightening, flaring, spinning, and extrusion forming to achieve precise processing of chassis oil pipes.

Front and Rear Subframes: Hydraulic pipe forming technology is commonly used to manufacture front and rear subframes. During the processing of subframe pipes, pipe end forming machines can perform operations such as flaring, necking, and flanging on the pipe ends to meet the structural and assembly requirements of the subframe, thereby enhancing its strength and stability.

Drive Axle Housings: Drive axle housings can also be manufactured using the hydraulic pipe forming process. Pipe end forming machines can conduct forming treatments (e.g., expansion, shaping) on both ends of the pipes used for drive axle housings, enabling them to meet the shape and size requirements of the axle housing and improving its load-bearing capacity.

Control Arms: Control arms are usually made of pipes. Pipe end forming machines can process both ends of control arm pipes—such as forming bends at specific angles, flaring, or necking—to facilitate connection and assembly with other components, ensuring the motion accuracy and reliability of the control arm.

Sway Bars: During the manufacturing of sway bars, pipe end forming machines can perform forming processes (e.g., end flattening, bending) on both ends of the pipes. This allows the sway bar to connect better with other components of the suspension system and fulfill its function of stabilizing the vehicle body.
