Description

Technical Field

[0001] The invention belongs to the technical field of production of accessories for new energy charging piles, and in particular relates to a heat dissipation hole stamping tooling for a new energy charging pile transformer shell. Background Art

[0002] The role of heat dissipation hole stamping tooling in the production of new energy charging pile transformer shells is mainly reflected in the following aspects: 1) Improved heat dissipation performance: The charging pile transformer will generate a certain amount of heat during operation. If this heat cannot be dissipated in time, it may cause the temperature of the equipment to rise, affecting its normal operation and life. By stamping heat dissipation holes on the shell, the heat dissipation performance of the shell can be greatly improved, so that the internal heat can be dissipated in time through air convection, thereby reducing the operating temperature of the transformer and ensuring its stable operation. 2) Improve equipment safety: The charging pile transformer is a key equipment in the charging process of new energy vehicles, and its safety is of vital importance. The design of the heat dissipation hole not only helps to dissipate heat, but also to a certain extent prevents safety hazards such as fire caused by overheating, thereby improving the safety of the equipment. 3) Optimize the production process: The application of heat dissipation hole stamping tooling makes the production of the shell more standardized and automated. Through the tooling, it can be ensured that the position and size of the heat dissipation holes of each shell are consistent, thereby improving production efficiency and quality. At the same time, the stamping process also reduces the links of manual operation and reduces production costs. 4) Adapt to complex environments: Charging piles are usually installed outdoors and need to withstand the test of various severe weather conditions. The design of the heat dissipation holes not only helps to dissipate heat, but also improves the weather resistance of the shell to a certain extent, enabling it to better adapt to complex usage environments.

[0003] The traditional heat dissipation hole stamping tooling for the new energy charging pile transformer shell has shortcomings when used. First, for the thin-walled aluminum alloy casting shell used in the new energy charging pile transformer, it is easy to cause large deformation at the punching part during the stamping process; second, the heat dissipation hole formed by it does not have a rainproof function, which affects outdoor use. Therefore, it is necessary to optimize and improve the tooling structure. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems existing in the traditional technology and provide a heat dissipation hole stamping forming tool for the shell of a new energy charging pile transformer.

[0012] Furthermore, in the heat dissipation hole stamping tooling for the new energy charging pile transformer shell, the positions of the convex tube forming holes and the hollow stamping columns correspond one to one, and the two together form a convex tube forming area for forming the inner convex tube.

[0013] Furthermore, in the heat dissipation hole stamping tooling for the new energy charging pile transformer shell, the diameter of the punching rod and the diameter of the heat dissipation hole match each other.
