重型汽车从动桥轴管冷推方成形技术

Cold Square-forming Technology of driven Axle Beams of Heavy-Duty Trucks

通过对重型汽车从动桥轴管加工工艺的改进,设计冷推方成形设备,实现轴管一次性冷推方成形,有效地解决了以往折弯后拼焊组合的落后工艺问题,提高了生产效率、降低了生产成本并增强了轴管的力学性能。

Cold square-forming equipment is designed to realize one-time axle beam cold square-forming by improving beam processing technique of heavy-duty axles, which effectively solves the problem of old technique that axle beams are first bended and then welded. It greatly enhances production efficiency, lower cost and improve the beam＇ s mechanical properties.
