Problems solved by technology
[0003] Due to the complex structure, heavy weight and many processes of the guide arm, the traditional leaf spring production methods and equipment require repeated heating and segmental hot pressing during the production of the guide arm, resulting in serious surface decarburization. Large fluctuations in size, low pass rate, and high kinetic energy consumption. In addition, because most of them are single-machine operations, manual loading and unloading, labor-intensive, and labor costs are high, the existing production technology and equipment cannot meet the large-volume, professional, and high-quality guide arms. Efficient demand reduces the economic benefits of the enterprise

Description
technical field [0001] The invention relates to the field of air suspension guide arm manufacturing, in particular to a method for side bending forming of a guide arm. Background technique [0002] Air suspension is an important part of commercial vehicles. Air suspension uses air spring as elastic element, which has the advantages of adjustable load capacity, stiffness changing with load, low natural frequency, etc. The guide arm is loaded and guided in the air suspension. Function, the guide arm can be divided into three categories: "L, Z, S" according to the structure. Generally, high-strength spring steel such as 51CrMoV4 is used. After blanking, heating, rolling, end forming, drilling, quenching and tempering, spraying Pills, monolithic electrophoresis, press sleeves, assembly, packaging and other processes are completed. [0003] Due to the complex structure, heavy weight and many processes of the guide arm, the traditional production methods and equipment of leaf spr...
