Design and manufacture of continuous die for electric vehicle copper bar

2025-06-23

In the field of electric vehicles, copper bar undertakes the task of converting electrochemical energy into mechanical energy, so the design and manufacture of copper bar die have high requirements. In the process of designing and manufacturing copper bar molds, a variety of factors need to be considered comprehensively, including mold materials and hardness, material forming and strengthening design, mold Angle calculation, copper bar design and extrusion.

First of all, in the choice of mold materials, the bearing capacity and corrosion resistance of the copper bar need to be taken into account. In general, the hardness of the mold material needs to reach a certain standard to ensure the molding quality and service life of the copper bar. At the same time, in order to improve the corrosion resistance of the mold, special treatment can be carried out on the surface of the mold, such as chrome plating, galvanized, etc.

Secondly, in the mold forming and strengthening design, the shape and size of the copper bar need to be taken into account. In general, the shape and size of the copper bar need to be designed according to the specific needs of the electric vehicle. In the design process, it is necessary to consider the factors such as the large width to thickness ratio and the large expansion ratio of the copper bar to ensure the continuous extrusion effect of the copper bar.

In addition, in the Angle calculation of the mold, the Angle and shape of the copper bar need to be taken into account. In general, the Angle and shape of the copper bar need to be designed according to the specific needs of the electric vehicle. In the design process, the N3 value of the copper bar needs to be taken into account to ensure the continuous extrusion effect of the copper bar.

Finally, the bearing capacity and corrosion resistance of the copper bar need to be taken into account in the design and extrusion of the copper bar. In general, the carrying capacity and corrosion resistance of copper bars need to be designed according to the specific needs of electric vehicles. In the design process, it is necessary to consider the maximum current and peak current size and duration of the copper bar to ensure the service life and stability of the copper bar.

To sum up, the design and manufacturing of electric vehicle copper strip continuous mold needs to consider a variety of factors, including mold materials and hardness, material molding and strengthening design, mold Angle calculation, copper strip design and extrusion. Only when these factors are fully considered, can we design a copper bar mold that meets the needs of electric vehicles, so as to ensure the normal operation and service life of electric vehicles.
