| titleOfInvention | Lithium battery positive and negative pole material ceramics cutting mould |
| abstract | The present invention discloses a kind of lithium battery positive and negative pole material ceramics cutting mould, including upper cutter head and lower tool apron, the lower end of the upper cutter head is equipped with downwardly projecting ceramic formed punch, the lower tool apron is equipped with the edge of a knife cooperated with ceramic formed punch, installation through-hole is provided on the ceramic mold, metal braces are inlaid in the installation through-hole, the ceramics formed punch screws togather removable be fixedly installed on upper cutter head by bolt and metal braces.The present invention replaces traditional wolfram steel material by using ceramic material, fever is easy when solving the work of wolfram steel material, when punching because copper powder, aluminium powder attachment due to make copper foil, there is the problem of burr in the die cut surface of aluminium foil, greatly improve the punching quality of copper foil, aluminium foil；By the way that metal braces are arranged on ceramic formed punch, the problem of it is inconvenient to efficiently solve traditional ceramic mold installation, complex procedures. |
