[Technical field]

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a rotary cutting die device for a battery shell port of a new energy vehicle. [Background Technology]

[0002] At present, in the rotary cutting process of the port of the battery shell of new energy vehicles, since the rotary cutting blade is a whole blade, if the gap is made just right, the surface will be scratched when the concave mold plate is pressed down. Therefore, in order to prevent scratches, the gap of the concave mold is often made very large. However, when the gap is made very large, burrs and eversion will occur at the corners, which is a pain point in the industry.

[0003] As mentioned above, through the traditional mold processing technology, burrs are often left on the edge of the square shell of the new energy vehicle battery. Due to the presence of burrs, it is often necessary to add an inspection machine after the stamping process, which greatly increases the equipment investment cost and even requires manual scraping of burrs. [Contents of the utility model]

[0026] Before the improvement of the utility model, the traditional mold process was used, which would leave burrs on the edge of the battery square shell. Due to the existence of burrs, it is necessary to add a mouth inspection machine after stamping, which greatly increases the equipment cost. However, through the process reform of the mold of the utility model, burrs can be eliminated, so there is no need for a mouth inspection machine, which greatly reduces the cost of parts. In addition, the traditional blade is a full blade type. If the gap is made just right, its surface will be scratched. In order to prevent scratches, the gap of the die can only be made very large. If it is made very large, there will be burrs at the corners. The utility model makes all the blades movable. When the die plate is pressed up, the die plate is pressed down when the mold is closed. It can fit the product very well, with basically no gap, so no burrs will be generated and it will not turn outward. In addition, in the traditional process structure, when the top plate is pressed against the template, due to the rotary cutting, surface-to-surface friction is generated, and the friction will cause jumping. After the improvement, all places where there is surface friction are equipped with plane bearings, so that it becomes rolling friction. The friction coefficient of rolling friction is negligible and there is no vibration source. The vibration caused by friction and the blade clearance of the die are the main causes of burrs. The utility model overcomes this problem by adding plane bearings to all static friction places, that is, changing it to rolling friction, and making the blade into a split movable blade, so that burrs and eversion can be solved.
