What are the advantages of metal stamping manufacturing process

At present, the quality metal stamping  manufacturing process has become an important part in the parts manufacturing industry, most of the stamping hardware is used in aerospace, automotive, shipping, machinery, chemical and other fields.So what are the advantages of metal stamping manufacturing process?

As for the metal stamping china manufacturing process as a whole, stamping process is mainly affected by the type of equipment, workpiece material, oil performance three factors, this article xiaobian to introduce:

I. Technological advantages of metal stamping

1, metal stamping parts is in the data consumption is not big under the premise, by stamping manufacturing, its parts light weight, good stiffness, and the sheet metal through plastic deformation, the arrangement of the structure of the metal interior has been improved, so that the strength of stamping parts to improve.

2. Metal stamping parts have high scale precision, uniform scale and good interchangeability.General installation and operation requirements can be satisfied without further machining.

3, in the stamping process, because the material appearance is not damaged, so there is a good appearance quality, beautiful appearance lubrication, which for the appearance of painting, electroplating, phosphating and other appearance processing provided a convenient condition.

Two, metal stamping material selection

Stamping process mainly has three kinds: blanking, bending, drawing, different processes have different requirements for the plate, material selection should also be based on the general shape of the product and processing technology to consider the choice of the plate.

1, blanking requires that the plate should have enough plasticity to ensure that the plate does not crack during blanking. The soft material has good blanking performance, after blanking, smooth section and small inclination can be obtained.The quality of hard material is not good after blanking, the cross section is not smooth, especially serious to thick sheet material.For brittle materials, tearing is easy to occur after blanking, especially when the width is very small.

2. The sheet that needs bending should have enough plasticity and lower yield limit.High plastic sheet is not easy to crack when bending, low yield limit and low elastic modulus of the sheet, after bending, the springback deformation is small, easy to get the size of the bending shape.The brittle material must have a large relative bending radius when bending, otherwise it is easy to crack during bending.

3, plate drawing, especially deep drawing, sheet metal processing technology is a more difficult, not only requires the depth of drawing as small as possible, the shape as simple as possible, smooth transition, but also requires the material to have a good plastic, otherwise it is very easy to cause the parts of the whole distortion, local wrinkling, or even tensile parts tensile crack.

Three, metal stamping oil selection

Stamping oil plays a key role in stamping process, good cooling performance and extreme pressure anti-wear performance for the service life of the die and the improvement of workpiece precision has a qualitative leap. According to the different material of the workpiece, the key point of the stamping oil is also different.

1, silicon steel plate is relatively easy to blanking material, in order to clean the workpiece, in order to prevent the burr produced by blanking under the premise of the use of low viscosity stamping oil.

2, carbon steel in the selection of stamping oil should be based on the difficulty of the process and drawing oil method and degreasing to determine the better viscosity.

3, galvanized steel and chlorine additives will have a chemical reaction, so galvanized steel in the selection of stamping oil should pay attention to the chlorine stamping oil may occur white rust problem.

4, stainless steel plate is easy to harden material, requires the use of high oil film strength, anti-sintering stretch oil.The stamping oil containing sulfur-chlorine compound additive is generally used to ensure the extreme pressure performance and avoid burr and rupture of the workpiece.

Above is the metal stamping manufacturing process what are the advantages? In this paper.With the rapid development of precision stamping technology, small stamping workpiece can meet the needs of various types of machine tools, electrical appliances, instruments and other manufacturing industries.

The above is the advantages of metal stamping manufacturing process, I hope you will like!Weihua technology is a metal stamping service companies, welcome to consult
