Product details：
Hefei Metalforming Intelligent Manufacturing Co., Ltd. and the Institute of High Stress Hydrostatic Forming of Harbin Institute of Technology (HIT) have closely cooperated in the program of "production-teaching-research". We have mastered the key technologies of internal hydrostatic forming and successfully developed digital equipment and production lines for this process. This has greatly improved the productivity and quality of products, achieving efficient mass production of high quality.
Purpose:
It is used to manufacture components such as automobile frames, engine mounts, exhaust pipes, crankshafts, automobile axles, suspension and other parts. It is one of the effective ways of lightweight automobile design.
Technical Features：
- Multi-variant motion control technology based on hydraulic axis.
- Energy saving technology of hydraulic press and internal high pressure.
- Ultra-high pressure source (400 MPa) and control technologies.
- Intelligent robots for monitoring the entire production line of large equipment and internal high pressure production lines.
Principle and Technology of Internal Hydrostatic Forming:
The tubular blanks are placed in a die. The two ends of the blank are sealed and additional material is pumped in. High hydraulic pressure is created inside the blank, which causes the tube to be formed into the desired shape. This method is used for mass production of lightweight, complex-shaped hollow parts. Compared with hydraulic expansion technology, internal hydrostatic forming achieves higher hydraulic pressure and more stringent control of the internal pressure loading process. This can achieve greater material deformation and produce tubular parts with complex three-dimensional shapes.
