Processing technology used: cutting, welding, bending, etc.
The stern shaft is the last part of the shafting, and the head flange is connected with the intermediate shaft flange with fitting bolts; The tail end is in conical shape for installing propeller. Stern shaft is forged with high-quality carbon steel.
Process: cutting, welding, bending, etc.
1. The spiral blade produced by the continuous cold rolling method overcomes the shortcomings of the traditional spiral blade production process, such as poor precision, difficult forming and high consumption of materials, and low production efficiency.
2. After the blade is formed, the surface is smooth and the dimensional accuracy and surface hardness are high.
3. Provide continuous integral blades according to the helical length required by customers, with good rigidity, convenient and fast welding and assembly during use.
