The principle and process of fine-blanking parts in a stamping factory-hardware

In the production of the stamping processing plant, the basic principle of strong press plate fine blanking is to use a special (three-way force) press to make the material produce plastic-shear deformation under strong action with the help of a special (three-way force) press, so as to obtain high-quality fine blanking parts. . The fine blanking machine is a special equipment to realize the fine blanking process. During fine blanking, there are three forces (PS, PR, PG) on the fine blanking machine that act on the mold. Before punching starts, through the ring gear force PR, through the guide plate outside the shear line, the V-shaped gear ring is pressed into the material and pressed against the die, thereby generating lateral pressure on the inner surface of the V-shaped gear ring to stop the material Tearing in the shear zone and lateral flow of metal outside the shear zone. At the same time, the back pressure PG presses the material on the punch by the ejector in the shearing line, and in the pressed state, it is punched under the action of the punching force PS. The metal in the shear zone is in a three-dimensional compressive stress state, thereby improving the plasticity of the material. At this time, the material follows the shape of the die edge and blanks the part in the form of pure shear. After the blanking is finished, the PR and PG pressures are released, the mold is opened, and the parts and waste are ejected by the withdrawal force PRA and the ejector force PGA respectively.
