Application and characteristics of metal stamping parts

 

Metal stamping parts by press and die on the plate, strip, pipe and profile, so as to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece (metal stamping parts) forming processing method. Stamping and forging belong to plastic processing (or pressure processing), collectively called forging. The blank is mainly hot rolled and cold rolled steel plate and strip. Stamping is mainly classified by process, which can be divided into two categories: separation process and forming process.

Metal stamping parts are mainly metal or non-metal sheet materials, with the help of the pressure of the press, through the stamping die stamping forming, it has the following characteristics:

Metal stamping parts is in the material consumption is not big under the premise of, by punching out, its parts light weight, good stiffness, and the sheet metal after plastic deformation, the internal structure of the metal has been improved, so that the strength of metal stamping parts to improve.

The metal stamping parts with higher dimensional accuracy, with the die size uniform consistent, there is a good interchangeability. General assembly and service requirements can be met without further machining.

3 hardware stamping parts in the stamping process, because the surface of the material is not damaged, so there is a good surface quality, smooth and beautiful appearance, which for the surface painting, electroplating, ** and other surface treatment to provide convenient conditions.

 

Application features

Metal stamping parts by means of the power of conventional or special stamping equipment, so that the sheet material in the die directly by deformation force and deformation, so as to obtain a certain shape, size and performance of the product parts production technology. Sheet metal, die and equipment are the three elements of stamping. Stamping is a kind of metal cold deformation processing method. So, called cold stamping or sheet metal stamping, short for stamping. It is one of the main methods of metal plastic machining (or pressure machining) and also belongs to material forming engineering technology.

In the steel, there are 50 ~ 60% of the plate made, the majority of this is after punching pressed into the finished product. Automobile body, radiator, boiler drum, container shell, electric motor, electrical core silicon steel sheet, whatever stamping processing. There are also a large number of metal stamping parts in instruments, household appliances, office machinery, storage utensils and other products. Stamping is a highly effective measure of puccinoplication, adopt compound die, abnormal is multi-station progressive die, it can be used in one pressure press to finish multi-channel stamping technology operation, finish automatic generation of material. Production speed, long rest time, low cost of puccinia corticioides, can produce hundreds of pieces of corticioides per minute, it is popular in many factories.

 

Metal stamping parts and castings and forgings have the characteristics of being thin, even, light and strong. Stamping can improve the rigidity by making the workpiece with reinforcing bars, ribs, coils or flanges which are difficult to make at the ripe hand diameter. Due to the rejection of the rough mold, the workpiece precision up to micron level, and high precision, consistent specifications, can punch out holes and pits, boss, etc. In the actual production, the process test similar to the stamping process is commonly used, such as drawing performance test, bulging performance test and other tests to check the stamping performance of materials, in order to ensure the quality of finished products and high pass rate.

Stamping equipment in addition to the thick plate with hydraulic press forming, usually adopt the stagnation press. Focusing on current high speed multi-station stagnation press, setting up equipment configuration uncoiling-off, product collection, delivery stagnation, mold base and quick mold change placement, and using computer French tube line, it can be used to build passive stamping lines with high puccinoplication rate. Under the condition of tens and hundreds of hardware stamping parts per minute, we can finish pressing and production in short time, it often happens human, fit and quality.
