Product Information

Horizontal expanding machine

It is used for the expanding‑sizing operation following rim rolling, whereby precise expansion by the expanding die ensures that the final diameter of the rim meets the product’s design specifications.

Main features

1. The expanding and lifting machine adopts an integral frame structure, providing high overall rigidity and helping to ensure machining accuracy.

2. It employs a dual‑power active expansion method, allowing the rim to be expanded and adjusted independently on both sides, making it convenient to use.

3. The main slider utilizes linear guide rails, ensuring high precision and stable operation.

4. The mold is securely mounted on the main slide, effectively preventing mold deflection and eliminating the occurrence of workpiece dimensional inaccuracies caused by such deflection.

5. The mold features an easy‑removal design; when changing molds, the entire unit can be lifted out, facilitating operation and saving time.

6. The expanding mold features a 12‑petal pyramidal design with inclined‑surface guidance, offering long service life and high operational accuracy.

7. Hydraulically driven, zero pollution, zero emissions, and stable operation.

8. The fully automatic production line can be optionally equipped with an automated loading and unloading system.
