Description

Die cutting tool, graphite die cutting process and graphite product Technical Field The invention relates to the technical field of graphite die cutting, in particular to a die cutting tool, a graphite die cutting process and a graphite product. Background In the die cutting production process of the artificially synthesized graphite film product, because of the special edge wrapping structure of the graphite film product, in the flat plate small hole sleeving process, the low-viscosity protective films are required to be arranged on two side surfaces of the graphite to be matched for use, so that the sleeving small holes can be reserved on the main material belt for subsequent die cutting station sleeving after the die cutting of the graphite body is completed. In this way, one of the protective films is at risk of adhering to the finished graphite, and the graphite product is disqualified. It should be noted that, the applicant believes that the background art is only for the purpose of raising the technical problem of the present application and is not equivalent to the prior art.
