Steel Wheel Rim Horizontal Expanding Machine

1. The hydraulic expanding machine comes with an integral frame structure that guarantees a high strength and machining accuracy.
2. The expander uses a dual power expanding method, allowing both edges of the rim to be expanded and adjusted.
3. The main sliding block moves on a linear guide, which ensures the high precision and stable movement.
4. A mold is fixed on the main sliding block, which can effectively prevent it from going down, which avoids non-standard work pieces.
5. The molds on the expanding equipment are specially designed for easy disassembly. When changing the molds, they can be lifted out integrally, which saves time.
6. The expanding mold is made up of 12 pyramids with a bevel guiding, enabling a long service life and a high running precision.
7. The expanding machine is driven by a hydraulic system, allowing it a stable performance.
8. An automatic load and unload system is optional.
