People say that the car, first appeared in front of the car body. That is, the car body is the logo of the car assembly. The body represents the image of the car. Car mold from the narrow sense is to punch the car body all the stamping parts of the mold in general. That is, "car body stamping die." For example, the top cover flanging mold, beam reinforced plate pressure die and so on.
The most important part of the auto parts mold is the cover mold. This type of mold is mainly cold die. Broadly speaking, "car mold" is the manufacture of all parts of the car mold in general. For example, stamping dies, injection molds, forging dies, casting wax molds, glass molds and so on.
The stamping parts on the car body are generally divided into covers, beams and general stamping parts. The stamping parts that can express the characteristics of the car image are car covers. Therefore, more specifically the car mold can be said to be "car cover stamping die." Referred to as car cover die. For example, the front door outside the board trimming die, the front door plate punching die and so on.
Of course, there is not only a car on the car stamping parts. All stamping parts on the car are called "car stamping die." To sum up is:
1. Car mold is the manufacture of all parts of the car mold in general.
2. Auto stamping die is punching all the stamping parts of the car mold.
3. Auto body stamping die is the car body car all the stamping parts of the mold.
4. Auto Cover Stamping Die is a tool for punching all the covers on a car body.
Now we have a plate that a car mold seems to refer to the car cover die. In order not to be confused with the broad sense of the car die, it is best to use the car cover when the stall die without a car die.
Stamping die in many forms, die also according to the nature of work, mold structure, mold materials to three categories.
Generally can be classified according to the following main features:
1. According to the nature of the process
A die that produces a separate mold along a closed or open contour. Such as blanking mold, punching die, cutting die, cutting die, trimming die, cutting and so on.
b. bending mold: the blank or other blanks along the straight line (bending line) bending deformation, so as to obtain a certain angle and shape of the workpiece mold.
c. drawing die: the blank is made of open blank hollow parts, or hollow pieces to further change the shape and size of the mold.
d. forming mold: the rough or semi-finished workpiece according to the figure convex, concave mold shape directly copy forming, and the material itself only produces local plastic deformation of the mold. Such as bulging mold, necking die, flaring mold, undulating forming mold, flanging mold, plastic mold and so on.
2. According to the degree of process combination classification
a. single process mode: in the press of a trip, only to complete a stamping process of the mold.
b. composite mold: only one station, in the press of a trip, in the same station at the same time to complete two or more stamping process die.
c. progressive die (also known as continuous mode): in the direction of the blank feeding, with two or more stations, in the press of a trip, at different stations to complete two or two Road stamping process above the mold.
3, according to the product processing methods classification
According to the different processing methods, mold can be divided into punching die, bending mold, drawing mold, forming mold and compression mold five categories.
a. punching die: is to complete the work of the role of shear, commonly used in the form of shear die, cutting punch, punching die, trimming die, the whole die, punching die and punching die.
b. bending mold: the flat hair is bent into an angular shape, depending on the shape of parts, precision and production of the amount of, there are many different forms of mold, such as ordinary bending die, cam bending die, curling Die, arc bending die, bending punching and twisting die and so on.
c. Dosing Mold: The dough mold is made of flat hairs.
d. forming mold: refers to the use of a variety of local deformation method to change the shape of the embryo, the form of convex forming die, the edge of the forming die, necking die, hole flange forming die, round edge forming die.
e. Compression die: the use of strong pressure, so that metal hair embryo flow deformation, as the required shape, the types of extrusion die, embossing die, stamping die, end die.
