Tubeless flaring die
Product Overview
This die features an integral structural design and is primarily used for the one‑step flaring and diameter‑expanding forming of steel wheel rims or agricultural vehicle rims. The monolithic flaring die applies uniform radial expansion forces directly to the workpiece via a rigid, integral cavity, making it well suited for high‑precision, small‑batch production, large‑diameter applications, or situations where exceptionally smooth surface finish is required.
Key Features
No evidence of lobation lines: Since the mold cavity surface is seamless, the inner and outer walls of the flared workpiece are smooth and even, free of sharp edges or weld marks, thereby eliminating the need for subsequent grinding.
Extremely high rigidity: The die is integrally forged—typically from Cr12MoV or H13—and achieves uniform hardness after heat treatment, making it resistant to deformation under high extrusion loads.
Excellent forming accuracy: Overall machining ensures the roundness and taper consistency of the die cavity; after flaring, the workpiece’s ovality can typically be controlled within ≤0.3 mm, with angular tolerances of ≤±0.5°.
Long lifespan: There is no wear gap between the active modules, resulting in more uniform wear across the entire working surface.
