Products Description
The stamping process used by Stamping Beryllium Copper Electrical Spring Contacts is an efficient metal processing method. It has significant advantages in mass production of complex and high-precision metal parts. It has high production efficiency and can ensure the consistency and interchangeability of products, but it has strict requirements on molds and equipment. In the stamping process, ensuring the accuracy of the stamping die is the top priority.
process characteristics
Stamping can achieve extremely high production efficiency.
Beryllium Copper Electrical Contacts with complex shapes that are difficult to process by other processing methods, such as thin shell workpieces, can be obtained.
The dimensional accuracy of Beryllium Copper Metal Stampings is related to the accuracy of the mold; therefore, the size is relatively stable and the interchangeability is high.
The material utilization rate is high, and the stamping energy consumption is low; the cost per unit of Beryllium Copper Connectors is low.
How to ensure the accuracy of stamping dies in the stamping process?
Accurate size design:
When designing the die, the size of each part of the die should be determined according to the dimensional accuracy requirements of the stamped parts. For the outer dimensions of the stamped parts, the influence of the blanking clearance on the die size should be considered. For example, the blanking clearance is generally about 5% - 10% of the material thickness. When designing the blanking die, the size of the concave die should be equal to the outer dimensions of the stamped part, and the size of the punch should be reduced according to the blanking clearance. For stamping parts with higher precision requirements, the blanking clearance may be controlled at 3% - 5% of the material thickness to ensure that the dimensional accuracy of the Beryllium Copper Stamping Parts is within a very small tolerance range.
Reasonable structural planning:
Select a suitable die structure according to the stamping process and the complexity of the shape of the Beryllium Copper Metal Stampings. For stamping parts with simple shapes, such as round or square gaskets, a single-process die structure can meet the requirements. However, for parts with complex shapes and multiple stamping processes, such as brackets in automotive parts, a compound die or progressive die structure is required.
Physical properties of beryllium copper
Density:
The density of Beryllium Copper Electrical Contacts is about 8.25-8.8g/cm³. Compared with ordinary copper materials, its density is relatively large, which makes it need to be considered comprehensively in some applications that require weight, but in some parts that require higher quality and stability, its density characteristics can also be an advantage.
Melting point:
The melting point is around 1080-1100℃. The high melting point enables it to maintain good structural stability in high-temperature environments and is not easy to deform or melt, which provides a basis for the application of Beryllium Copper Connectors under some high-temperature working conditions.
Thermal conductivity and electrical conductivity:
It has excellent thermal and electrical conductivity. This feature makes Beryllium Copper Metal Stampings widely used in electronics, electrical and other fields that require high thermal and electrical conductivity, such as the connection of electronic components, heat dissipation components, etc.
Color and appearance:
It usually presents a purple-red color similar to ordinary copper, but after special treatment, its surface can obtain better gloss and color uniformity, with good appearance decoration, which can meet some applications that have high requirements for the appearance of Stamping Spring Contacts Beryllium Copper Alloy.
