Divided by the direction of the force, the hydraulic press has two types, vertical and horizontal. Most hydraulic presses are vertical, hydraulic presses with two-column hydraulic presses This series of products are suitable for press-fitting, bending and shaping, embossing, creasing, punching and shallow stretching of small parts of various parts; metal powder Product molding and other processing technology. It adopts electric control and is equipped with jog and semi-automatic circulation. It can maintain pressure delay, and has good slider orientation, convenient operation, easy maintenance, economical and durable. According to the needs of users can add thermal instruments, top cylinder, digital display, counting and other functions.
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. It has been obtained in the industrial field, especially in the automobile industry. More and more applications. In the automotive industry, aerospace, and other fields, reducing the structural quality to save energy in operation is a long-term goal pursued by the people and is also one of the trends in the development of advanced manufacturing technologies.
Hydroforming is an advanced manufacturing technology for achieving lightweight construction.
Hydroforming is also referred to as "internal high pressure forming". Its basic principle is that the pipe material is used as a blank, and an ultra-high pressure liquid is applied inside the pipe while axial thrust is applied to both ends of the pipe blank for feeding. Under the joint action of two kinds of external forces, the tube blank material undergoes plastic deformation and is finally attached to the inner wall of the mold cavity to obtain a hollow part whose shape and accuracy meet the technical requirements.
