Five key steps to master the essence of the stamping process cutting process

In the stamping process, the cutting process is a key link, which directly affects the quality and productivity of stamped parts. Master the following five steps to master the essence of the cutting process.

1. Definition and role of cutting process

Cutting process refers to the process of separating the stamped part from the whole sheet metal. Its main function is to remove the excess material around the stamped part and make it conform to the shape and size required by the design.

2. Selection of cutting method

According to the shape, size and material properties of the stamped part, a suitable profiling method can be selected. Common profiling methods are: shearing, punching, laser cutting and so on. Shearing is suitable for simple shaped stamping parts, punching is suitable for complex shaped stamping parts, and laser cutting is suitable for stamping parts with high precision requirements.

3. Design and manufacture of cutting mold

Cutting mold is an important tool in the processing of stamping parts, and its design and manufacture are directly related to the quality of cutting process. When designing the cutting mold, the following factors need to be considered:

(1) Selection of mold material: the mold material should have sufficient hardness, strength and wear resistance to ensure the service life of the mold and the quality of the stamped parts. Commonly used mold materials are high-speed steel, carbide, etc..

(2) Design of mold structure: the structure of the mold should be simple, reasonable, easy to install and maintain. At the same time, the structure of the mold should also be conducive to the release and discharge of stamped parts.

(3) Design of die edge: the shape, size and sharpness of the die edge directly affect the effect of the cutting process. When designing the edge of the mold, it is necessary to make reasonable selection and calculation according to the characteristics of the stamped parts and the requirements of the cutting method.

4. Setting of cutting parameters

Cutting parameters refer to various parameters to be controlled in the cutting process, such as punching pressure, punching speed, punching depth, etc. Reasonable cutting parameters can improve the effect of the cutting process. Reasonable cutting parameters can improve the quality of stamped parts and reduce production costs. When setting the cutting parameters, it is necessary to adjust them according to the characteristics of the stamped parts and the requirements of the production process.

5. Precautions for the operation of cutting process

In order to ensure the quality and production efficiency of the stamped parts, the operator needs to pay attention to the following points in the cutting process:

(1) Strictly follow the operation procedures to avoid quality problems of stamped parts caused by improper operation.

(2) Regularly check the use of cutting molds, find problems in time to deal with.

(3) Keep the working environment neat and clean to prevent debris from entering the stamping equipment and affecting the quality of stamped parts.

(4) Strengthen the awareness of safe production, comply with the safety operation regulations, and prevent accidents.
