Product Description

Vertical Expanding Machine for Steel Wheel Rim Production

In the steel wheel rim manufacturing line, the vertical expanding machine is placed behind the roll forming machine. It is an important piece of wheel rim machinery for expanding and sizing the rim after the roll forming process. With the use of accurate expanding on this expanding press, the diameter of the formed rims can meet customer's design requirements.
The expanding machine is a special equipment in wheel production. It is used to expand the deformation after the processing on rim welding seam, so as to get the rim that meets the size requirements. The two expanding machines are placed on the left and right sides, sharing a set of hydraulic system. The expanding range of the smaller expanding unit isφ190.8-φ350, and the expanding range of the bigger one is φ350-φ408.9.

Main Features

 

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.
