Application of hydroforming technology on stamping parts

Hydroforming is a shaping technology that refers to the use of liquids or molds to shape workpieces, also known as hydraulic forming. Hydroforming technology can do many stamping processes, such as punching, bending, stretching, etc. Using hydroforming technology, stamping processing plants can process a variety of complex stamping parts, such as bellows. The stamping products produced by hydroforming have the advantages of good surface quality, simplified process and simplified molds, which greatly simplifies the processing procedures of stamping processing plants. However, because the liquid directly acts on the stamping parts, it is much more difficult to achieve the sealing requirements, and the operation process is more complicated. The following is a precise introduction to the main advantages and limitations of hydroforming: Hydroforming has outstanding advantages: 1. This technology is isostatic forming, which relies on high-pressure media to change the shape of the sheet. The raw material is compressed in the normal direction and is under stress in three directions, which can better perform partial forming and make it easier to process more complicated stamping parts; 2. Change the traditional steel-steel contact forming method, Effectively reduce scratches on stamping products and optimize the appearance of products to a large extent. 3. Break through the limitations of traditional stamping in the forming direction of stamping parts. 4. Multiple processes can be carried out at once, which is beneficial to reduce the number of processes and molds. However, hydroforming technology also has disadvantages. Requires external liquid medium and its corresponding equipment; requires follow-up processing of parts before welding; considering the impact on the on-site operating environment, it is not suitable for mass stamping parts processing.
