Publisher:admin Add time:2019/10/17 viewed:1752


Preliminary contact mold industry or in the mold industry for many plays functions of management or sales position colleagues, understanding of mould many degree are very vague and difficult to understand, so a lot of mould enterprises in the beginning can make entry of personnel to the scene of the production practice, only in the process of practice can go close to understand the basic knowledge of the mould, the following offer is some very image of the principle of the mold, the different cognitive.

Stamping die according to the nature of the process: punching die, bending die, stretch die, forming die, riveting die

1, blanking die: along the closed or open contour line to produce a separate material mold. Such as blanking die, punching die, cutting die, cutting die, cutting die, etc.

2, bending die: the blank or other blank along a straight line (bending line) to produce bending deformation, so as to obtain a certain Angle and shape of the workpiece mold.

3, drawing die: is the blank made of open hollow parts, or hollow parts to further change the shape and size of the mold.

4, forming die: is the blank or semi-finished workpiece according to the figure of convex, concave die shape directly copy, and the material itself only produce local plastic deformation of the mold. Such as bulging die, shrink die, flaring die, relief forming die, flanging die, plastic die.

5, riveting die: is to borrow external forces to participate in the parts in accordance with a certain order and way of connection or overlap together, and then form a whole.

According to the classification of working procedure combination, the mould can be divided into four categories: single working procedure mould, compound mould, progressive mould and transfer mould.

1. Single process die: only one stamping process die is completed in one stroke of the press.

2, compound die: only one station, in a stroke of the press, in the same station to complete two or more stamping process of the mold.

3, progressive die (also known as continuous die) : in the direction of the blank feed, with two or more stations, in a stroke of the press, in different stations to complete two or more stamping process of the mold.

4, transfer mold: integrated single process mold and progressive mold characteristics, the use of manipulator transfer system, to achieve the rapid transfer of products in the mold, can greatly improve the production efficiency of products, reduce the production cost of products, frugal material cost, and the quality of stable and reliable.

According to the different processing methods, the mould can be divided into punching and shearing mould, bending mould, drawing mould, forming mould and compression mould.

1, punching and shearing die: shear die, blanking die, punching die, trimming die, whole edge die, punching die and punching and cutting die.

2, bending die: is the flat hair blank bending into an Angle shape, depending on the shape of the parts, precision and the amount of production, there are a variety of different forms of mold, such as ordinary bending die, CAM bending die, edge rolling die, arc bending die, bending seam die and twisting die.

3. Pumping mold: the pumping mold is to make the flat wool embryo into a seamless container with a bottom.

4, forming die: refers to the use of a variety of local deformation methods to change the shape of the blank, the form of the punch, roll edge forming die, necking forming die, hole flange forming die, circular edge forming die.

5, compression die: is the use of strong pressure, the metal hair blank flow deformation, into the required shape, the types of extrusion die, embossing die, embossing die, end press die.

Stamping die basic components: on the cover plate, mold base, on plate, plate, plate, stripper, templates, and the mold base, guide material components, punch, the stripper plate insert, guide is nail, feeding error detection device, guide pin, guide sleeve, guide pin, guide sleeve, column spacing, guide pin, fixed bolt, screw, spring discharge, discharge screw.
