Abstract

The invention belongs to the technical field of lithium battery pole piece cutting equipment, and particularly relates to a cutting die which comprises a first die, a second die, a pressing device and an anti-vibration device. The first die comprises a metal layer and at least two inorganic non-metal layers, and the metal layer is arranged between the two inorganic non-metal layers. The first layer of the metal layer is connected with one inorganic non-metal layer, and the second end of the metal layer is connected with the other inorganic non-metal layer. According to the cutting die, after precision machining forming, the precision after machining can be kept for a long time, it is guaranteed that the deformation degree of the first die, the deformation degree of the second die and the deformation degree of a corresponding first cutter and the deformation degree of a corresponding second cutter are within 0.002 mm at the temperature ranging from minus10 DEG C to 50 DEG C, lateral force generated when equipment is installed is counteracted, vibration is reduced, and the precision in use is guaranteed. Through the effects that the ceramic material brings stability to the die and reduces the weight and the metal layer protects the ceramic material from being broken easily, the phenomena of powder falling and burrs cannot occur in the cutting process, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting equipment for lithium battery pole pieces, in particular to a cutting die. Background technique [0002] In the process of cutting the positive and negative electrodes by the existing cutting mold, the serious problems of powder dropping and burrs are prone to occur, because the influence of the processing accuracy and structure of the mold eventually leads to such bad cutting effect, and at the same time, the existing The upper mold is generally made of iron. The overall weight of this upper mold is relatively heavy. Therefore, when the positive and negative electrodes of the lithium battery are cut by continuous lifting and moving, a large vibration will be generated, resulting in the failure of the finished product. Low precision and high error; [0003] Moreover, when the existing mold is processed, the vibration is relatively large, the precision of the finished product is low, and the servi...
