| Abstract: | For a new energy vehicle battery rack hollow aluminum profile,the porthole extrusion die was designed,and the finite element simulation technology was combined to obtain the flow velocity distribution of the aluminum alloy during the aluminum profile extrusion process.By analyzing the data obtained from the simulation,an improvement plan was proposed for the mandrel die structure in view of the unevenness of the metal extrusion speed.The improved simulation results showed that the metal flow rate at the exit of the profile was uniform.The die trial test was consistent with the finite element simulation results,which provided guidance for the design and improvement of the die structure of the relevant profile. |
