Trailer Axle Double-head Flash Butt Welding Machine

The American-style axle is the most widely used axle type in China. It adopts integral molding technology and the representative manufacturer is Fuhua. Its processing procedures are complex, the process route is long, and the equipment investment is large. It is characterized by no welding process. The current molding process is mature. But after welding the forks to the axle, it still needs to be straightened.

The German axle is a three-section welded axle, which is welded by two precision-machined axle heads and the middle axle tube. The representative manufacturer is German BPW. Since the axle head can be finely machined and welded to the axle tube, the processing steps are fewer than that of an integrated axle, and equipment investment can be significantly saved.

There are currently three methods of welding axles, namely axle friction welding, axle CO2 welding and axle flash butt welding. Their respective characteristics are as follows:

1. The axle friction welding machine is a welding method introduced earlier in China. In the early days, it was entirely imported equipment, which was expensive. In recent years, it has been replaced by domestic products, but the equipment cost is still high. It can only weld round shafts, not square shaft tubes, and the welding speed is moderate. In most cases, a straightening process is required after welding the forks.

2. CO2 automatic welding machine is also a relatively mature welding process. Before welding, the shaft tube and shaft head need to be beveled, and then multi-layer and multi-pass filling welding is performed. CO2 welding always has welding defects such as slag inclusions and pores that cannot be avoided (especially when welding square shaft pipes), and the welding speed is slow. The advantage is low equipment investment. There is also an alignment process required after the axle is welded to the fork.

3. Special machine for double-head flash butt welding of axles. Axle double-head flash butt welding machine is used for welding. This equipment is a special welding machine developed and customized by Suzhou Agera for the trailer axle welding industry. It has fast welding speed, no defects such as slag inclusions and pores after welding, and the quality of the weld is close to or reaches that of the base material. strength. It can be perfectly compatible with the welding of round and square axes, and can be welded after the fork and swing arm are welded. No alignment process is required after welding, which greatly improves welding efficiency and quality and reduces welding costs.

Suzhou Agera can also fully automate the axle flash welding process according to customer needs to realize automatic loading, welding, and unloading of axles to reduce the intensity of manual work and human quality and safety issues, while further improving axle welding efficiency.

Trailer axles play an important role in long-distance road transportation. The significance of improving its processing quality and processing efficiency is self-evident. With the steady growth of market demand for road transportation vehicles and the axle manufacturing industry facing the current situation of urgent need for equipment upgrading, Agera Automation has developed a double-head flash butt welding machine for the axle for the industry, which will provide the industry with high efficiency, high precision and automation. Advanced manufacturing equipment with high degree of accuracy and low manufacturing cost is of great significance to promoting the development of road transportation and national economic construction.
