Advantages of hydraulic presses

Release Time:2022-5-25 16:15:23      Hit Count:503

Compared with the traditional stamping process, the hydroforming process has obvious technical and economic advantages in reducing weight, reducing the number of parts and molds, improving stiffness and strength, and reducing production costs, and has been widely used in the industrial field, especially in the automotive industry. more and more applications. In the automotive industry, aviation, aerospace and other fields, reducing structural mass to save energy in operation is a long-term goal of people, and it is also one of the trends in the development of advanced manufacturing technology. Hydroforming is an advanced manufacturing technology to achieve lightweight structure. Hydroforming is also known as "internal high pressure forming". Its basic principle is to use the pipe as a blank, apply high-pressure liquid inside the pipe, and apply axial thrust to both ends of the pipe blank to replenish the material. Under the combined action of the two external forces, the material of the tube blank undergoes plastic deformation and adheres to the inner wall of the mold cavity to obtain a hollow part whose shape and precision meet the technical requirements.
