Technical Field

[0001] The invention relates to the technical field of casting processing, and in particular to an automatic shaping device for die-casting of a car battery housing. Background Art

[0002] At present, the battery shell of the car is cast. The structure of the battery shell casting is complex, and its shaping work is highly dependent on manual measurement and manual shaping by skilled workers. The current existing die-casting shaping scheme mainly measures the degree of deformation manually, then manually fixes the die-casting and uses a leather hammer to knock on the deformed part to achieve the desired goal. The main tools for manual shaping include: measuring ruler and leather hammer. The shaping of die-castings relies heavily on manual experience. Manual shaping is easily affected by the technical level and experience of the operator, resulting in unstable product quality and difficulty in ensuring the accuracy and consistency of each product. Human factors can easily lead to errors in the shaping process, affecting the dimensional accuracy and surface quality of the product, and increasing the scrap rate of the product. At the same time, it takes a lot of manpower and time, the production efficiency is relatively low, it cannot meet the needs of large-scale production, and increases production costs.

[0003] In summary, the shaping of existing automobile battery shell castings relies on manual processes, which has technical problems such as low shaping efficiency and unstable quality. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the shaping of existing automobile battery shell castings relies on manual processes, which has the technical problems of low shaping efficiency and unstable quality.

Since the main purpose of the shaping correction of the battery shell die-casting is to make the flatness and parallelism of the side plates on both sides meet the standard requirements, in order to ensure the effectiveness of the correction, a plurality of shaping wrenches driven by a linear drive cylinder in each group of shaping cylinder groups are moved in a direction perpendicular to the side plate surface of the battery shell. The battery shell is moved and the shape of its side panel is changed to meet the standard requirements. The shaping wrench has a groove structure that can accommodate the edge of the side panel of the battery shell. Therefore, the shape of the side panel of the battery shell can be changed by the displacement of the shaping wrench and the interaction with the adjacent shaping wrenches, and the deformation amount of the battery shell is obtained through the shape sensor. The position of the shaping wrench is controlled according to the acquired data, so as to achieve precise and automated sheet metal shaping, which effectively solves the technical problems that the shaping of existing automobile battery shell castings relies on manual craftsmanship, and has low shaping efficiency and unstable quality.

[0012] As a preferred solution, the clamp mechanism includes an end corner clamp whose position corresponds to the end corners of the battery shell, which is used to press the end corners of the battery shell against the top surface of the support platform mechanism. The end corner clamp includes a clamping cylinder arranged perpendicular to the mounting plate, and the piston rod end of the clamping cylinder is connected to a pressure rod arranged perpendicular to the piston rod. This design optimizes the structural design of the clamp mechanism. The end corner clamp is arranged at the four corners of the battery shell, and the vertically arranged clamping cylinder drives the pressure rod to press vertically downward to press the four corners of the battery shell downward and fix it to the support platform mechanism.

[0013] As a preferred solution, the clamping mechanism also includes two clamping mandrels arranged at a preset distance, the clamping mandrels respectively corresponding to the inner wall positions on both sides of the battery shell to be shaped, and one end of each clamping mandrel is provided with a pin connection structure rotatably connected to the mounting platen; two pushing structures are arranged at a preset distance between the clamping mandrels, which are used to push the two clamping mandrels laterally to increase the distance between the two to clamp and fix the battery shell.

The battery shell die-casting can be fixed at a preset position on a mounting platen through the cooperation of a support platform mechanism and a clamp mechanism. The shaping and correction component has a shaping cylinder group corresponding to the side plate structure on both sides of the battery shell die-casting.
