The wheel rim reinforcement pieces usually require a smaller bending radius to fit the shape of the wheel arch. The problem is that the small radius forming process is prone to causing material cracking.
The common troubles faced by customers:
Micro cracks appear at the edges of the sheet after forming;
After long-term use, these cracks will expand, resulting in the destruction of the parts;
Low material utilization rate and high scrap rate.
The solution provided by the forming machine:
Through multiple progressive transitions, avoid excessive bending in a single step;
The roller wheels adopt R-shaped transitions instead of sharp corners to reduce the concentration of stretching;
For high-strength steel materials, local induction heating can be selected to improve ductility.
This type of knowledge is precisely the most troublesome issue for customers in actual production and is also what they most hope to solve from the equipment side.
