An Overview of Automobile Dies

2019/6/23 18:49:15 Viewers:

The main component of automobile die is panel die. This kind of die is mainly cold stamping die. In a broad sense, "automobile die" is the general name of the die for manufacturing all parts of the automobile. For example, stamping mold, injection mold, forging mold, casting wax mold, glass mold and so on.


The stamping parts of automobile body are generally divided into covering parts, beam frame parts and general stamping parts. The stamping parts which can clearly express the image characteristics of automobile are automobile panels. Therefore, the more specific automobile die can be said to be "automobile panel stamping die". Abbreviated as automobile panel die. For example, the trimming die for the front door outer panel, the punching die for the front door inner panel, etc.

Of course, not only the body of the car has stamping parts. Dies for all stamping parts on automobiles are called "automobile stamping dies". To sum up, it is:

1. The automobile die is the general name of the die for manufacturing all the parts on the automobile.

2. The automobile stamping die is the die for stamping all the stamping parts on the automobile.

3. The stamping die for automobile body is the die for stamping all stamping parts on automobile body.

4. The stamping die for automobile panels is the die for stamping all automobile panels.

Now, when we talk about automobile die, it seems that we all refer to automobile panel die. In order not to be confused with the generalized automobile die, it is better to use automobile panel die instead of automobile die when posting.

There are many kinds of stamping dies. The stamping dies are classified according to their working properties, die structure and die materials.

Generally, it can be classified according to the following main features:

1. Classification according to process properties

A. Punching Die: Die that separates materials along closed or open contours. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc.

B. Bending die: A die that bends a blank or other blank along a straight line (bending line) to obtain a workpiece with a certain angle and shape.

C. Deep drawing die: a die that makes a blank of a sheet into an open hollow part or makes the hollow part change its shape and size further.

D. Forming die: a die that directly reproduces the shape of the convex and concave die of a blank or semi-finished product according to the figure, while the material itself produces only local plastic deformation. Such as bulging die, necking die, expanding die, undulating forming die, flanging die, shaping die, etc.

2. Classification according to the degree of process combination

A. Single process die: In one stroke of press, only one stamping process is completed.

B. Compound die: a die with only one working station, which can complete two or more stamping processes at the same working station in one stroke of the press.

C. Progressive Die (also called Continuous Die): In the direction of blank feeding, there are two or more positions. In one stroke of press, two or more stamping processes are completed at different positions one by one.

3. Classification according to the processing method of products

According to the different processing methods of products, the dies can be divided into five categories: punching and shearing dies, bending dies, drawing dies, forming dies and compression dies.

A. Punching and shearing dies: the work is completed by shearing. The common forms are cutting die, blanking die, punching die, trimming die, flanging die, drawing die and punching die.

B. Bending die: It bends flat hair embryo into an angle shape, depending on the shape, accuracy and production of the parts, it has many different forms of die, such as ordinary bending die, cam bending die, crimping die, arc bending die, bending punch and twisting die.

C. Pumping Die: Pumping Die is a seamless container made of flat hair germ.

D. Forming die: refers to the use of various local deformation methods to change the shape of the hair embryo, in the form of convex forming die, flange forming die, necking forming die, hole flange forming die, flange forming die.

E. Compression die: It uses strong pressure to make the metal hair germ flow and deform into the required shape. Its types include extrusion die, embossing die, embossing die and end-pressing die.
