Industrial hydraulic press dies the introduction of its principle
Stamping processing has high requirements for stamping dies. To make high quality and high precision stamping parts, it is necessary to have the corresponding dies. The various processes of stamping are to make the sheet material form the required quality, shape, and scale of the workpiece, and the die is one of the primary factors affecting the required. industrial hydraulic press
Stamping dies are divided according to the nature of the process: blanking die, bending die, stretching die, forming die, riveting die
1、Blanking die: along the closed or open contour line to make the material to produce separation of the die. Such as drop die, punching die, cutting die, notching dies, cutting edge die, cutting die, etc.
2、Bending die: make the slab blank or other blanks along the straight line (bending line) to produce bending deformation, so as to obtain a certain angle and shape of the workpiece of the mold.
3、Drawing die: It is the mold to make the sheet blank into open hollow parts, or make the hollow parts further change the shape and size.
4、Forming die: It is a die that makes a direct copy of the blank or semi-finished workpiece according to the shape of the convex and concave die, and the material itself only produces local plastic deformation. Such as expansion die, indentation die, flaring die, undulation forming die, flanging die, shaping die, etc. industrial hydraulic press
5, riveting die: is to borrow external force to make the parts involved in accordance with a certain order and way to connect or lap together and then form a whole. industrial hydraulic press
According to the processing method, the die can be divided into five categories: punching and shearing die, bending die, drawing die, forming die and compression die, etc.
1、Punching and shearing die: is to shear role to complete the work, the common form of shear punching die, under the material punching die, punching die, trimming die, the whole edge punching die, pulling hole punching die and punching die.
2、Bending die: is the flat embryo bent into an angle shape, depending on the shape of the parts, precision, and production volume, there are a variety of different forms of die, such as ordinary bending die, cam bending die, rolled edge die, arc bending die, bending punching die and twist punching die.
4、Forming die: It is used to change the shape of the embryo by various local deformation methods, such as convex forming die, rolled edge forming die, neck shrink forming die, hole flange forming die, round edge forming die.
5、Compression die: It uses strong pressure to make the metal embryo flowing and deforming to become the desired shape, and its types are extrusion die, embossing die, embossing die, end pressure die.
