Guide arm side bending forming method

Abstract

The invention discloses a guide arm side bending forming method, and relates to the field of air suspension guide arm manufacturing. The guide arm side bending forming method comprises a marching-typeheating furnace, a positioning device, a side bending machine, a hydraulic forming machine and an oil quenching tank, and can realize batch production, moreover, multi-directional forming is completed at a time through quenching heating, heating decarburization is reduced, the quality is stable, the machining efficiency is high, energy consumption is reduced, the production cost is low, the automation degree is high, and the guide arm side bending forming method has better comprehensive economic benefits, and is convenient to popularize.

Description

technical field [0001] The invention relates to the field of air suspension guide arm manufacturing, in particular to a side bending forming method for the 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 changes with load, and low natural frequency; the guide arm plays the role of load and guide in the air suspension Function, the guide arm can be divided into three types "L, Z, S" according to the structural form, generally using high-strength spring steel such as 51CrMoV4, after blanking, heating, rolling, end forming, drilling, quenching and tempering, spraying Pills, single-chip electrophoresis, pressing, assembly, packaging and other processes are completed. [0003] Due to the complex structure, heavy weight and many processes of the guide arm, the traditional leaf spring production methods and equipmen...

AI Technical Summary

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
