Stamping process operation specification

Stamping process and its characteristics stamping is a pressure processing method that uses the die installed on the press to exert pressure on the material at room temperature to produce separation or plastic deformation, so as to obtain the required parts. Stamping is usually cold deformation processing of materials at room temperature, and mainly uses sheet metal to process the required parts, so it is also called cold stamping or sheet metal stamping.

Stamping is one of the main methods of material pressure machining or plastic machining. It is a material forming engineering technology.

In stamping processing, the special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) is called stamping die (stamping die for short). Stamping dies are as like as two peas in stamping process, and are not exactly the same as stamping parts. If there is no stamping die that meets the requirements, the qualified stamping parts can not be produced. There is no advanced die

The stamping process can not be realized.

Compared with mechanical processing and plastic processing, stamping processing has many unique advantages in terms of technology and economy, mainly as follows:

(1) Stamping processing has high production efficiency, convenient operation and easy to realize mechanization and automation. This is because stamping is completed by stamping dies and stamping equipment. The stroke times of ordinary press are dozens of times per minute, and that of high-speed press can reach hundreds or even thousands of times per minute, and one or more stamping parts can be obtained each stamping stroke.

(2) as like as two peas, the stamping die ensures the size and shape accuracy of stamping parts, generally does not destroy the surface quality of stamping materials, and the life of dies is generally longer. So stamping parts have stable quality and good interchangeability, and have the same characteristics.

(3) Stamping can process parts with large size range and complex shape, such as the second hand of clocks and watches, automobile longitudinal beam and covering parts. Coupled with the cold deformation hardening effect of materials during stamping, the strength and stiffness of stamping parts are high o

(4) Stamping generally has no chip and scrap generation, less material consumption and no other heating equipment, so it is a material-saving and energy-saving processing method.

(5) The cost of stamping parts is low.

Stamping part processing is the production technology of product parts with the help of the power of conventional or special stamping equipment to make the sheet directly subject to deformation force and deformation in the die, so as to obtain a certain shape, size and function.

Stamping parts processing is one of the main businesses of our company. Here are the operation specifications in the process of stamping parts processing:

1. A strict inspection system shall be established during the processing of stamping parts. Stamping parts must be comprehensively inspected first, and can be put into production only after passing the inspection. At the same time, patrol inspection shall be strengthened, and accidents shall be handled in time.

2. Adhere to the civilized production system. For example, appropriate station tools must be used for the transmission of workpieces and blanks, otherwise the workpiece surface will be crushed and scratched, affecting the surface quality of the workpiece.

3. During the stamping process, ensure that the mold cavity is clean, the workplace should be organized, and the processed workpieces should be placed neatly.

4. Raw materials must conform to the specified technical conditions, strictly check the specification and brand of raw materials, and test and inspect the workpieces with high dimensional accuracy and surface quality if possible.

5. All links specified in the stamping process specification shall be fully and strictly observed.

6. The press, die and other tooling equipment used shall be guaranteed to work under normal working conditions.

Stamping parts processing is one of the main methods of metal plastic processing. Stamping parts are used in various mechanical equipment, so the processing quality of stamping parts must be guaranteed.
