- In enclosed forging for cross joints, the die structure has been changed from the vertically symmetrical two-split type to a vertical four-split type to prevent enclosing force control from generating burrs on the shaft parts.
- Elastic deformation of dies during forming has been controlled by optimizing the enclosing load, and cost reduction has been achieved by improving the roundness of the shaft parts to eliminate cutting.
- As this engineering method makes die correction work no longer necessary and can improve mass productivity and tool longevity, its application to other forged parts is expected.
Spider joint
Forming conditions
- Material
- Steel
- Size
- Minimum: 60 mm, Maximum: 200 mm (Total length of both shafts)
- Applications
- In automobiles, spider joints are mainly used in portions where rotational force is transmitted in an angled state. To cut to the chase, the primary application is drive shafts. Spider joints are mainly used on propeller shafts and serve as critical parts to transmit rotational force even in an angled state. In particular, spider joints are required for front-engine, rear-wheel-drive vehicles, four-wheel-drive vehicles, and trucks.
