What is the Dongguan metal stamping? In fact, in fact, the metal stamping is a kind of cold processing technology, a special process equipment used to process metal materials into parts or shapes. It is called cold stamping die, and there are also cold stamping dies in China. Stamping, usually at room temperature, is carried out at room temperature. The die is installed on the punching machine, and then the pressure is applied to the material to produce plastic deformation, so that the material becomes the mold shape, and a pressure processing method is obtained for the required parts. Dongguan metal stamping die drawing machine is very simple. A standard equipment in the market is the bearing body of the mold. The punching machine has the difference between the size and the size. In view of the size of the stamping products and the thickness of the material, the punching machine of different tonnage should be selected.
The shape and accuracy of the parts play a decisive role in the stamping die, which is very important. The accuracy of the die determines the accuracy of the parts. Therefore, the structure of the mold, the type of mold is also a lot.
From the hardware stamping process, the common mold should have the following processes:
1 blanking die, along the closed or open contour, make the material separate the mold. For example, the blanking die, the punch die, the cutting die, the cut die, the cutting die, the cutting die and so on are often seen. These all play the role of blanking, so it is called blanking die.
2 deep drawing die is a mold that is used to draw materials into open hollow parts, or to further change the shape and size of hollow parts.
The 3 forming die is to directly copy the blank or semi-finished workpiece according to the shape of the convex and concave die, while the material itself produces only local plastic deformation mold. For example, bulging die, necking die, expanding die, forming die, flanging die, shaping die, etc.
The 4 riveting die is to use external force to connect or join parts in a certain order and form, thus forming a whole.
In terms of the process of metal stamping in Dongguan, the mold can have the following categories:
1 single die, this is the simplest mold in the mold, one can be formed, in one action of the punching machine, only a stamping process is completed.
2 compound die, only one process and action, in one action of the punching machine, complete two or more metal stamping dies at the same time in the same process.
3 continuous mold, some master also known as the progressive die, this is a more difficult mold in the mold, using the automatic material feed, with two or more processes, in the punch press, in the one action of the press, in different processes to complete two or more than two stamping die.
4 transfer mode, combining the characteristics of single process die and continuous stamping die, using the manipulator transfer system to realize the rapid transmission in the mould, can greatly improve the production efficiency of the product, reduce the production cost, the cost of frugal material, and the quality of the product is stable and reliable, which is the characteristic of the mould maintenance.
With the use of hardware parts more and more widely, and the requirements of the parts are getting higher and higher, so the requirements for the mold are also becoming higher and higher. In this road, China still has a long way to go, and there are also higher challenges and breakthroughs.
