Why is the stamping continuous die cut and bent?
Stamping process is an efficient and economical manufacturing method in the field of metal processing, which is widely used in automotive, electronics, home appliances and other industries. As an important tool in the stamping process, the design and manufacturing quality of continuous die directly affect the shape, size and surface quality of the product. This paper will discuss the deformation problems that may occur in the process of cutting and bending of stamping continuous die and its causes, and put forward the corresponding solutions.
With its high production efficiency and low cost advantages, stamping continuous die occupies an important position in modern manufacturing industry. However, in the actual production process, the cutting and bending process of the mold is often accompanied by the deformation of the material, which not only affects the quality of the product, but also may reduce the service life of the mold. Therefore, in-depth analysis and solution of these problems is of great significance for improving production efficiency and product quality.
The working principle of stamping continuous die
Before introducing the cutting and bending deformation problem in detail, we first need to understand the working principle of the stamping continuous die. Continuous dies are usually composed of multiple stations, each station to complete different processing tasks, such as punching, bending, drawing, etc. The material moves continuously in the mold, through the processing of various stations, and finally forms the desired product shape.
Deformation problem during cutting
Cutting is one of the basic steps in the stamping process, its purpose is to separate the material into the desired shape and size. During the cutting process, the material may undergo the following types of deformation:
1. Elastic recovery: After cutting off, the material will undergo elastic deformation under the action of stress, resulting in dimensional instability.
2. Burrs: Due to the action of shearing force, cutting the edge may produce burrs, affecting the appearance and accuracy of the product.
3. Bending: The material may be bent during the cutting process, especially in thin sheet materials.

3. Bending: The material may be bent during the cutting process, especially in thin sheet materials.
Deformation problem during bending
Bending is the process of machining the flat material into the desired shape. Common bending deformation problems include:
1. Rebound: After bending, the material may rebound under the action of elastic force, resulting in angles and shapes that do not meet the design requirements.
2. Cracks: During the bending process, the internal stress of the material may exceed its strength limit, resulting in cracks.
3. Creasing: When the material is compressed during the bending process, it may wrinkle.

Deformation cause analysis
The deformation problem in stamping continuous dies is usually related to the following factors:
1. Material characteristics: the strength, hardness, elastic modulus and other characteristics of the material have a direct impact on the deformation.
2. Mold design: the geometry, size and material selection of the mold are crucial to deformation control.
3. Processing parameters: including pressure, speed, lubrication conditions, etc., will affect the degree of deformation.
4. Equipment accuracy: The accuracy and stability of stamping equipment are also important factors affecting deformation.
