CNC machining solutions for various longitudinal and transverse beams in the manufacturing of battery enclosures for new energy electric vehicles

(Original: Hama Technology, please do not plagiarize)

The following figure shows a typical structure of a new energy vehicle battery tray, which is a frame structure consisting of longitudinal beams, transverse beams, and a middle transverse beam+convex hull bottom plate.

Among them, each side beam is made of 6-series aluminum alloy extruded profiles and processed by CNC profile machining centers.

Figure 2 shows a typical side beam longitudinal beam diagram of the power battery box of a new energy electric vehicle. The typical length of the side beam ranges from 500-1800mm and requires machining of the mating surfaces at both ends, weight reduction ports, weight reduction slots, mating ports, upper cover holes, etc. Interiors can be processed on one side, while complex ones may require processing on two, three, or even four sides. In mass production, it is generally necessary to produce hundreds of sets per day, so in order to be efficient, in addition to making corresponding fixtures for clamping and positioning, it is also necessary to choose machine tools with fast speed and high processing efficiency. Simple single-sided machining can be completed by using flat fixtures, while complex edge beams require multi-faceted machining. Multiple clamping is generally not preferred, as multiple clamping requires multiple fixtures and occupies machine resources. Frequent loading and unloading of materials also consumes human resources. Due to the poor rigidity of profiles, the accuracy of multiple clamping machining cannot be guaranteed. So generally, for those that require multi-faceted processing, the fixture is designed as a rotating fixture, so that all features can be processed in one clamping. Time saving, labor-saving, and resource efficient, greatly reducing processing costs while also greatly improving processing efficiency.

As shown in Figure 3, the length of the processed edge beam is about 1.8 meters, requiring 4 sides to be processed. The plan uses a Deli HCZ6500 high-speed machining center. The operating speed of the equipment in the X-axis length direction reaches 60 meters per minute, which greatly improves the idle running speed and processing speed of high-speed machine tools for profile processing. The fixture in this scheme is a rotating hydraulic fixture (all fixtures are connected by hidden pipelines), which is installed at stations A and B on the left and right sides. The left and right doors of the machine tool are automatic doors. When the operator is loading and unloading materials at station A, the spindle head is used to process the workpiece at station B, and it circulates back and forth. This way, the machine tool is constantly processing, greatly improving the utilization rate of the machine tool, and one person can also supervise two to three devices. Greatly saving labor costs.
