What are the characteristics of the stamping process and what are the characteristics of stamping?

Curved. Therefore, when the deep-drawn steel is deeply drawn, there is a possibility of cracking, which is characterized by the wall thickness of the workpiece after drawing is basically the same as the thickness of the blank before drawing, punching and resting and other processes. tailoring, so when the external force is canceled.

It is commonly used to be drawn without thinning, and the rebound angle should be compensated in advance. It is divided into thinning and drawing, and the basic process of thinning drawing stamping is divided into two categories: separation process and deformation process.

4. The degree of hardening increases. Drawing is a plastic deformation process: it is a deformation process that turns a flat blank into a hollow cup or box product, and the periphery is the finished product, so that the required accurate angle can be obtained after bending.

1。Blanking is to separate the blank according to the closed contour in order to continue drawing, that is, to cut the blank into strips or strips, etc.: it is a process that separates the blank according to the unclosed contour, and with the increase of the number of drawing.

Drawing. It is often used as a material preparation process. Such as bending radius; It is a process in which the blank is separated according to a closed profile.

3. The separating part is waste. The angle of rebound has to do with a lot of factors. The separation process includes cutting.

Therefore, when designing the bending die, the remaining part of the periphery is scrap. Blanking and punching, blanking, material thickness and metal properties, etc. Punching is to separate the blank according to the closed contour, generally 3-4 times should be annealed, the blank has a rebound phenomenon, that is, the elastic deformation part of the bent part is restored

It is a deformation process that bends the blank into a certain angle and shape, and the separated part is the finished product, and the degree of plastic deformation will increase. The deformation process includes bending and drawing. Because the bending deformation process is a process of plastic deformation and elastic deformation.

Stamping processing relies on dies and presses to complete the processing process, and its characteristics can be summarized as follows:

Stamping processing is to make metal or non-metal sheet under the simple impact of the press, through a punching die can complete the processing of more complex shape parts that can not be or is difficult to manufacture by other processing methods, because the accuracy of the parts is mainly guaranteed by the die, so the parts have higher precision, product quality stability, and higher interchangeability.

Parts with thin walls, light weight, good rigidity, high surface quality, and complex shapes that cannot or are difficult to manufacture by other methods can be obtained by using mold processing.

Stamping generally does not require heating of the blank, nor does it require a large amount of energy consumption as in metal cutting, which requires a lot of energy consumption.

The stamping process is extremely productive. Under normal circumstances, ordinary presses can produce parts from a few to dozens per minute, and if a high-speed punch press is used, it can be as high as hundreds of parts per minute, which is beyond the reach of other machining methods.

The stamping production operation is relatively simple, because the parts and quality status of the stamping production mainly rely on the mold and the machine tool to guarantee, resulting in less unstable factors in production, the stamping production operation only needs to be completed by a more conventional operation mode, and the production organization is more convenient. At the same time, it is also convenient to realize the automatic operation of stamping production through automatic machine tools.

The structural complexity and precision requirements of the stamping die are usually high, so the design and manufacturing cycle of the die is usually long, and the cost is also higher, so the economy of the stamping production method can only be fully reflected under the condition of mass production.

Stamping has high efficiency, saves raw materials, good interchangeability of products, and reduces processing costs.

Sheet metal stamping is a common machining process that is mainly used to produce metal parts of various shapes. The sheet metal stamping process includes the following:

1.Shearing: A shears are used to cut the sheet metal into the desired shape.

2.Punching: A punching machine is used to punch out the holes in a patterned arrangement on the sheet metal to facilitate the assembly and fixing of the parts.

3.Bending: Use a bending machine to bend the sheet metal slowly and widely along a certain bending line into the desired shape.

4.Deep drawing: A deep drawing machine is used to draw the sheet metal into the desired shape.

5.Die Casting: A sheet metal is placed into a die casting mold and extruded into the desired shape by high pressure.

6.Welding: Metal parts of different shapes are joined together through a welding process to form a complete product.

7.Surface treatment: surface treatment of sheet metal products, such as spraying, plating, etc., to protect the surface of the product and improve the aesthetics of the product.

These processes usually require the use of professional sheet metal stamping equipment and tools to ensure machining accuracy and production efficiency.

Stamping has the following 5 characteristics:

1. The size is guaranteed by the mold, and the quality of the processed parts is stable;

2. Stamping and forming can obtain parts that are not regretted by other processing methods or are difficult to manufacture;

3. High material utilization rate;

4. High efficiency and easy operation;

5. The mold has a long service life and low production cost.

5. The mold has a long service life and low production cost.

1) Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of larger quantities of parts and products, which is convenient for mechanization and automation, and has high production efficiency.

2) The operation process is convenient and does not require the operator to have a high level of technology.

3) The stamped parts generally do not need to be machined again, and have high dimensional accuracy.

4) The stamping parts have good interchangeability, the stamping processing stability is good, and the same batch of stamping parts can be exchanged with each other, which does not affect the assembly and product performance.

5) Because the stamping parts are made of plates, the quality of the stool on its surface is better, which provides convenient conditions for the subsequent surface treatment processes (such as electroplating and painting).

6) Stamping can obtain parts with high strength, high stiffness and light weight.

7) The cost of stamping parts mass-produced with molds is low.

8) It can also manufacture parts with complex shapes that are difficult to be processed by other metal processing methods
