How does a stamping work? What kind of job is a stamper?

Stamping parts are formed and processed by applying external force to plates, strips, pipes, and profiles by presses and dies to produce plastic deformation or separation, so as to obtain the workpiece (stamping part) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), which is collectively called forging. The stamped blanks are mainly hot-rolled and cold-rolled steel plates and strips.

60 70% of the world's steel is sheet, most of which is stamped into finished products. The body, chassis, fuel tank, radiator sheet of the automobile, the steam drum of the boiler, the shell of the container, the iron-core silicon steel sheet of the motor and electrical appliances are all stamping. There are also a large number of stamping parts in instruments and meters, household appliances, bicycles, office machinery, household utensils and other products.

Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can be used to produce workpieces with stiffeners, ribs, undulations or flanges that are otherwise difficult to manufacture to improve their rigidity. Due to the use of precision molds, the accuracy of the workpiece can reach the micron level, and the repeatability is high, the specifications are consistent, and the holes and bosses can be stamped.

Cold stamped parts are generally no longer machined or require only a small amount of machining. The accuracy and surface condition of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting is less.

Stamping is an efficient production method, the use of composite die, especially multi-station progressive die, can complete multiple stamping processes on one press, to achieve from strip uncoiling, leveling, blanking to forming, finishing of fully automatic production. High production efficiency, good working conditions, low production cost, generally can produce hundreds of pieces per minute.

Stamping is mainly classified according to the process, which can be divided into two categories: separation process and forming process. The separation process is also called blanking, the purpose of which is to separate the stamping parts from the sheet metal along a certain contour line, and at the same time ensure the quality requirements of the separation section. The surface and intrinsic properties of the stamping sheet have a great impact on the quality of the finished stamping product, and the thickness of the stamping material is required to be accurate and uniform. The surface is smooth and clean, no spots, no scars, no abrasions, no surface cracks, etc.; The yield strength is uniform, and there is no obvious directionality; High uniform elongation; low yield ratio; Low work hardenability.

The stamping parts are mainly metal or non-metal sheets, with the help of the pressure of the press, through the stamping die stamping processing, it mainly has the following characteristics: The stamping parts are manufactured by stamping under the premise that the material consumption is not large, the parts are light in weight and good in rigidity, and after the plastic deformation of the sheet, the internal structure of the metal is improved, so that the strength of the stamping parts is improved. The stamping parts have high dimensional accuracy, uniform size with the mold, and good interchangeability.

No further machining is required to meet general assembly and use requirements. In the stamping process, because the surface of the material is not damaged, it has good surface quality and smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.

Hardware stamping parts are formed by metal stamping process and mold, stamping equipment and stamping materials, hardware stamping processing has the advantages of high productivity, low die cost, no need for sheet metal shearing, progressive die can save 30% of the cost, but its application is limited by the depth of tensile, the surface hardening of the strip edge material of the guide and transmission, and is mainly used for simple parts with a relatively shallow drawing depth. Mould is the main process equipment of metal stamping processing, the surface quality, size tolerance, productivity and economic benefits of stamping parts are very related to the mold structure and its reasonable design, according to the combination of metal stamping process, there are simple dies of single process, continuous die and composite die of multiple processes. When formulating the stamping process of the workpiece, the dispersion and concentration of the processing process is a more complex problem, it depends on the batch of the workpiece, the structural shape, the quality requirements, the process characteristics, etc., for the automobile stamping parts that are usually produced in large quantities, the scheme of process concentration should be taken as much as possible, and the composite or progressive die is used for stamping, so as to improve the productivity and achieve safe production.

1. Stamping workers are personnel who operate stamping equipment and carry out workpiece deformation and separation processing and processing. Stamping is a forming process method that relies on presses and dies to apply external force to plates, strips, pipes, and profiles, etc., so that they produce plastic deformation or separation, so as to obtain the workpiece (stamping part) with the desired shape and size ridge.

2. Stamping operators are dangerous jobs, because they need to be in continuous contact with the machine and the workpiece, which is prone to the risk of extrusion and limb cutting.

3. It will be more tired. Stamping workers are high-intensity and repetitive operations, and people are easily tired and bored.

Stamping worker is a feeding lead ear processing, processing after the operation of the material to take out, but also to see the machine tool, maintenance of the machine tool, the production should also self-check the processed parts of the product whether there is an obvious abnormality, whether it is found that the machine tool and tool abnormalities or the processing of parts next to the family of abnormalities need to be stopped in time to react.

Good afternoon, dear<>

Stamping is a common metalworking technique. It deforms the metal sheet or metal strip by stretching, bending, compressing and other deformations under the action of the mold, and finally obtains the metal buried parts of the required shape and size. Stamping technology is widely used in the manufacture of metal parts in automobiles, electronics, home appliances and other products.

The workflow of stamping usually includes the following steps:1Design and manufacture of molds:

According to the design requirements of the product, the suitable stamping die is manufactured, the stamping die is usually composed of upper and lower parts, and the upper die and the lower die deform the metal sheet through stroke power. 2.Fabric:

Sheet metal or metal strip is fed into the press and fixed on the table by means of a positioning device. 3.Stamping:

The stroke power is activated, the upper die is pressed down and held at the end of the stroke for a period of time to allow the sheet metal to form the desired three-dimensional geometry. 4.Punching:

Punching is performed on metal parts, usually using punching dies. 5.Assembly & Surface Treatment:

Different parts are assembled together by welding, riveting, threading, etc., and surface treatment, such as spraying paint, etc. Stamping technology has the advantages of simple process, high production efficiency, stable quality and high precision, and is widely used in various fields. At the same time, according to different product types and requirements, different types of stamping processing such as deep drawing, fine drawing, diameter reduction, bending, and stretching can also be carried out.

In addition:1With the development of technology, the modern stamping process has a very high degree of automation, which can realize unmanned and fully automated production.

2.Stamping is not only suitable for sheet metal, but also for other materials, such as plastic, rubber, etc., but the specific process and the details of the mold design are different. 3.

The stamping machine is a special equipment for stamping processing, and the stamping machine on the market is divided into different types such as mechanical, hydraulic, and pneumatic. <>

Stamping is a process in which metal materials such as plates and pipes are deformed with molds to manufacture various parts. By placing a sheet or tube into a punching press, the die will press or shear the metal and dry it into shape. The stamping process is suitable for manufacturing various metal parts, such as automobile parts, housings of electronic equipment, home appliances, etc.

It can efficiently produce large quantities of identical or similar parts, and can meet the requirements of complex shapes and precise dimensions. Therefore, the stamping process is widely used in industrial manufacturing and is an important metal processing method.
