AI Technical Summary
In the traditional processing of new energy battery boxes, the cumulative punching errors lead to excessive coaxiality and spacing accuracy of the holes, making it difficult to meet the requirements of high-precision assembly. Furthermore, the hole inspection after forming cannot detect defects in time, resulting in low production efficiency and high costs.
By combining positioning and inspection components, multiple positioning components limit the positional relationship between the punched part and the formed part, and the inspection components perform rapid hole position checks to ensure hole position accuracy.
This reduces the cumulative punching error, improves the hole position accuracy after the box is formed, meets the requirements of high-precision assembly, improves production efficiency and overall production yield, and ensures the structural safety of the battery pack.

Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of battery box, in particular to a plate production device for new energy battery box. BACKGROUND
[0002] The new energy battery box is a core protection assembly for carrying and fixing battery modules and electric control components in a new energy vehicle / energy storage system, and has the functions of sealing, impact resistance, waterproofness and dustproofness. The box plate is first smelted and rolled to obtain a metal original plate (such as an aluminum alloy or high-strength steel), and then is subjected to flattening and stress pretreatment. As a core forming process, stamping is carried out by a numerical control punch press matched with a special die, and the plate is processed into box trays, end plates, cover plates and other components through processes such as blanking, punching, bending and stretching, so as to realize accurate forming of hole positions and special-shaped structures and to ensure that the plate meets the bearing and assembly requirements of the box.
[0003] In the traditional processing flow of the new energy battery box, a mode of "separate component punching + subsequent welding" is generally adopted. That is, the tray, end plate, side beam and other independent components are punched respectively, and then all the components are assembled into a complete box through the welding process. Due to the differences in the punching reference of each component, and the heat distortion generated in the welding process further affecting the relative positions of the hole positions, the punching errors of the multiple components are superimposed and accumulated, which easily causes the hole position coaxiality and spacing precision of the final box to exceed the standard, and it is difficult to meet the high-precision assembly requirements of module installation and pipeline docking. In addition, the existing process detects the hole positions after the box is partially formed. If the hole position deviation problem is found, the single component cannot be reworked and corrected, and only the whole can be scrapped or repaired at high cost, which not only reduces the production efficiency, but also greatly increases the manufacturing cost and quality risk.

The hole diameter and hole position accuracy are verified to ensure the precise assembly of the bolts, modules and other components, avoid the automatic installation jamming, avoid the influence on the protection performance and assembly reliability, and ensure the overall safety of the battery pack.
[0028] By arranging the positioning assembly and the inspection assembly, the cooperation of multiple positioning assemblies not only limits the parts to be punched, but also limits the positional relationship between the formed parts, reduces the superposition of punching errors, improves the hole position accuracy of the box after forming, and meets the high-precision assembly demand. The inspection assembly can quickly check the hole positions after punching, timely find the hole position deviation problem, ensure the safety of the battery pack structure, improve the production efficiency, and stabilize the overall production yield.
[0029] As an embodiment in the embodiment, as Figures 1 to 10As shown, the positioning component includes a side plate 4 fixedly connected to the top of the placement plate 3. The side plates 4 are symmetrically distributed, and each of the opposite surfaces of the side plates 4 has a groove 23. A slider 22 is slidably connected inside the groove 23. The outer contour dimension of the slider 22 is adapted to the inner wall dimension of the groove 23. A fixing triangle 9 is fixedly connected to the bottom of the slider 22. An inspection component is rotatably connected to the top of the fixing triangle 9. A locking nut 24 is threadedly connected to the top of the slider 22. The top of the slider 22 has a thread adapted to the locking nut 24. The groove 23 is distributed in upper and lower layers. The two sides of the box tray 5 and the opposite surfaces of the box side beam 6 near the top are in contact with the right angle surface of the fixing triangle 9. A right angle protrusion 10 is fixedly connected to the top of the fixing triangle 9. The bottom of the right angle protrusion 10 is in contact with the outer wall of the box tray 5 and the box side beam 6 respectively.
[0030] Specifically, the CNC punch press 1 and the punching head 2 are connected via a tool holder, which is fixed to the machine tool spindle and driven by the machine tool control system. This precisely controls the stroke, speed, and positioning of the punching head 2 to achieve hole machining. The cooling pipe on the side of the punching head 2 is connected to the machine tool cooling system (e.g., ...). Figures 1 to 2 As shown), cutting fluid is continuously sprayed during processing. Its core function is to quickly remove the heat generated by punching, preventing overheating and wear of the punch head 2 and deformation of the workpiece material. Simultaneously, it flushes away debris and burrs from the hole opening, ensuring a smooth hole wall, reducing subsequent cleaning processes, and improving processing accuracy and punch lifespan.

When the locking nut 24 is tightened to contact the outer wall of the side plate 4, it limits the position of the slider 22, thus fixing the position of the fixed triangle 9. When the locking nut 24 is tightened to separate from the outer wall of the side plate 4, the slider 22 can slide along the long axis of the sliding groove 23 (e.g., ...).
