Description

Technical Field

[0001] The utility model relates to the technical field of production of new energy charging pile accessories, in particular to a shaping tool for processing a new energy charging pile transformer shell. Background Art

[0002] The advantages of using aluminum alloy to manufacture thin-walled housings for new energy charging pile transformers include the following: 1) High Strength and Lightweight: Aluminum alloy is relatively light compared to other metal materials, yet possesses high strength. This allows aluminum alloy to ensure the housing's robustness while reducing overall weight, facilitating transportation and installation. This also reduces the burden on the entire system and improves overall efficiency. 2) Good Thermal Conductivity: Aluminum alloy possesses excellent thermal conductivity, enabling rapid heat transfer. Charging pile transformers generate a certain amount of heat during operation, and the aluminum alloy housing effectively dissipates this heat, preventing overheating and ensuring stable operation. 3) Corrosion Resistance: Aluminum alloy exhibits excellent corrosion resistance, enabling long-term use in harsh environments. This is particularly important for charging piles, as they are often used in complex environments, including coastal areas subject to harsh conditions such as ultraviolet rays and salt spray. The aluminum alloy housing effectively protects the electronic components within the transformer, extending its service life. 4) Good machinability: Aluminum alloys have good machinability and can be made into parts of various shapes and sizes through various processing methods (such as forging, die-casting, milling, and welding). This makes aluminum alloys highly flexible in manufacturing thin-walled housings for charging pile transformers, allowing them to meet different design requirements.

[0003] The thin-walled housings of new energy charging pile transformers are prone to localized deformation during processing, requiring reshaping and repair using reshaping tools. Traditional reshaping tools used for processing new energy charging pile transformer housings have shortcomings. First, they cannot fully preheat the reshaping area before heating; second, they cannot quickly adjust the position of the reshaping mechanism to meet the reshaping requirements of different positions on the new energy charging pile transformer housing. Therefore, optimization and improvement are needed. Utility Model Content

The two side plates of the groove plate 203 are respectively fixed with the horizontal shaping push rod 204 and the hot air blower 205. The movable end of the horizontal shaping push rod 204 is installed with a shaping head 207 through the mounting plate 206. A connecting cavity 209 and several air outlet channels 210 are provided inside the shaping head 207. The output end of the hot air blower 205 is connected to the side end of the connecting cavity 209 of the shaping head 207 through the air duct 208. One end of the air outlet channel 210 is connected to the connecting cavity 209, and the other end of the air outlet channel 210 extends to the outer side of the shaping head 207.

[0033] In this embodiment, the outer side surface of one shaping head 207 is a concave arc surface that matches the outer wall of the transformer cylindrical thin-walled shell 3, and the inner side surface of the other shaping head 209 is a convex arc surface that matches the inner wall of the transformer cylindrical thin-walled shell 3.
