Five principles of precision metal stamping processing
Modern precision metal stamping processing is an important processing technology for precision parts. Stamping processing is a high-precision processing, and its processing efficiency is high. The processed hardware has the characteristics of precision, fineness and exquisiteness, which has become an important part of metal processing. Craft. Many metal objects in our lives are added using this processing method. So what are the processing principles of this processing method, let’s take a look at it with the editor.
Precision metal stamping processing
1. Precision principle: The number of processes for drawing parts is related to material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, and needs to be recognized by drawing process accounting talent.
2. The principle of fineness: The number of processes for the bending part mainly depends on the messiness of its structure and shape, and it needs to be determined according to the number of bending angles, relative orientation and bending direction.
3. The principle of exquisiteness: When the section quality and standard accuracy of the stamping parts are high, you can consider adding a trimming process after the punching process or directly selecting a fine punching process.
4. Principle of precision: When blanking a workpiece with a simple shape, the single-process die can be used. When blanking a workpiece with a messy shape, due to the restriction of the structure or strength of the die, the surface and the inside of the workpiece should be divided into several parts. , Need to select multiple metal stamping processing procedures. When necessary, a continuous die can be selected. For workpieces with high flatness requirements, a leveling process can be added after the punching process to accurately adjust the characteristics of each product to the production process.

5. Quality principle: In order to ensure the quality of fine metal stamping parts, advancing the stability of the metal stamping process sometimes needs to increase the number of processes. For example, the additional positioning process hole punching of the bending part, the increased deformation reduction hole punching in the forming process to transfer the deformed area, etc., to ensure that each product is refined, refined and exquisite.
