The vacuum forming technology of the forging die of construction machinery is an advanced forming process. By establishing a negative pressure environment in the die and using the atmospheric pressure difference to drive the metal material to fill the cavity of the die, the manufacturing and forming of the die can be realized.
This technology has several advantages over traditional die casting or forging processes:
- Improve product quality: vacuum forming technology can eliminate porosity, inclusion and other defects, improve the density and strength of the product, reduce the porosity of the product, thereby improving the quality and service life of the product.
- Improve production efficiency: The use of mold vacuum forming technology can obtain higher pressure in a single filling, so that the metal material can fill the mold cavity more completely, reduce the secondary forming or repair process caused by incomplete filling, and improve production efficiency.
- Reduce production costs: mold vacuum forming technology can reduce the loss of materials and scrap rate, while avoiding the additional cost of secondary molding or repair, reducing manufacturing costs and production costs.
- Expand the freedom of design: vacuum forming technology can achieve complex shape forging die manufacturing and forming, for the design and production of construction machinery forgings to provide greater freedom, can meet the needs of different products.
However, mold vacuum forming technology also has some challenges and limitations:
- High equipment investment: The purchase and maintenance cost of vacuum forming equipment is high, which has certain requirements for the technical strength and financial strength of the enterprise.
- It is difficult to control process parameters: it is necessary to accurately control multiple parameters such as air pressure, temperature and cooling rate in the vacuum forming process, which requires high technical requirements and operational experience in the process.
- Limited material adaptability: There are differences in the adaptability of mold vacuum forming technology between different materials, and there are certain restrictions on the selection and formulation of materials.
In summary, mold vacuum forming technology is an advanced forming technology with a wide range of application prospects, by giving full play to its advantages, combined with the actual situation and demand, it can bring higher quality and benefits for the manufacturing and production of construction machinery forgings.
