In today's society, precision mold has been widely used in people's life, work and other corners, so do you know how the precision mold is classified? Today, for you to answer this question, the precision mold can generally be classified according to the following main features:
First, the precision mold can be classified according to the technological properties:
A. die for separating the material from the closed or open outline of the blanking die. Such as blanking die, punching die, cutting die, cut die, cutting die, cutting die and so on.
B. bending die causes the sheet blank or other blank to produce bending deformation along a straight line (curved curve), thus obtaining a mold for a workpiece with a certain angle and shape.
The C. drawing die is a mold that makes the blank blank of the sheet material into an open hollow piece or further changes the shape and size of the hollow piece.
D. forming die is a mould that produces the blank or semi-finished workpiece by the shape of the figure convex and the concave die, and the material itself only produces the local plastic deformation. Such as bulging die, necking die, expanding die, rolling forming die, flanging die, plastic mould and so on.
Two, the precision mold can also be classified according to the working procedure combination.
In one stroke of the press, the A. single process Die completes only one die for the stamping process.
The B. compound die has only one position. In one stroke of the press, two or more stamping dies are completed on the same station at the same time.
C. progressive die (also called continuous die) has two or more workstations in the direction of blank delivery, and two or two or more stamping processes are completed at different stations in one stroke of the press.
Three, precision molds may be classified according to the processing methods of products: products according to the different processing methods, can be divided into mould die, bending die, drawing die, mold and compression mold five categories.
A.: die is to finish the work to shear, commonly used form of cutting die, blanking die, punching and trimming die, trimming die, broaching die and punching die.
B. bending die: is the smooth hair Peiwan an angle shape, depending on the shape, accuracy and the amount of production, but there are many different forms of mold, such as bending die, bending die, flanging die cam, arc bending die, bending die punching seams and distortion die etc..
C. drawing: drawing die mold is the plane blank made of a seamless container.
D. forming die: it means to change the shape of the hairs with various ways of local deformation. It has the form of convex forming die, edge forming punching die, necking forming punching die, hole flanging forming die and circular edge forming punching die.
The E. compression mold is a powerful pressure that makes the metal hair germ flow and deform into the desired shape. There are extruded punching dies, embossing dies, imprint punching dies and end pressure punching dies.
