AI Technical Summary

Technical Problem

The existing stamping tooling cannot meet the processing requirements of the heat dissipation pipes of the aluminum shell for the heat dissipation of the charging pile transformer, resulting in unsatisfactory heat dissipation effect.

Method used

A stamping fixture comprising an adjustment component, a stamping component, a pressure-bearing component, a multi-axis robot, and an extrusion and closing component was designed. By adjusting the position, a serpentine heat dissipation convex tube is stamped and formed. The multi-axis robot is then used to perform rolling extrusion to form a serpentine narrow slit and oil inlet and outlet ports, thereby achieving efficient processing of the heat dissipation pipe.

Benefits of technology

This technology enables efficient heat dissipation of the aluminum shell of the charging pile transformer, ensuring stable operation of the transformer and battery life, and improving charging efficiency and safety.

Abstract

This utility model relates to the field of new energy charging pile accessory production technology, and in particular to a stamping tooling for processing the heat dissipation aluminum shell of a charging pile transformer. The tooling of this utility model is rationally designed. An adjusting component is used to adjust the initial position of the stamping component and the pressure-bearing component. The stamping component and the pressure-bearing component together stamp a serpentine heat dissipation protrusion on the side plate of the slotted shell. A serpentine groove is formed on the inner side of the serpentine heat dissipation protrusion. Then, a multi-axis robotic arm drives the extrusion rollers of the extrusion and closing component to approach each other and roll and extrude along the serpentine heat dissipation protrusion, gradually extruding the serpentine groove to form a serpentine narrow slit and oil inlet and outlet on both sides. Subsequently, a circulating oil pump is installed inside the slotted shell, which continuously pumps the transformer lubricating oil filled inside the slotted shell into the serpentine heat dissipation protrusion through the oil inlet and finally out through the oil outlet. The serpentine narrow slit has a small width, which does not affect the overall circulating flow and heat dissipation effect.
