Abstract
The invention discloses a pyrophyllite block pressing die and a pressing method thereof, and relates to the technical field of manufacturing the superhard material synthesis assistive devices. The pyrophyllite block pressing die comprises a die sleeve composed of an outer sleeve body and an alloy inner sleeve body embedded in the inner side of the outer sleeve body, an alloy die core is arranged in the alloy inner sleeve body, and the alloy inner sleeve body comprises an alloy upper inner sleeve y and an alloy lower inner sleeve; the alloy upper inner sleeve and the alloy lower inner sleeve are arranged in an up-down split and overlapped manner, a guide area of an upper pressing head is formed between the alloy upper inner sleeve and the alloy die core, and a pyrophyllite block product forming area is formed between the alloy lower inner sleeve and the alloy die core. The alloy inner sleeve is arranged in the up-and-down split manner, so that the alloy inner sleeve is made of materialswith different properties, and the property requirement for the alloy inner sleeve during the pressing process is met.
Description
technical field [0001] The invention relates to the technical field of making superhard material synthetic aids, in particular to a pyrophyllite block pressing mold and a pressing method thereof. Background technique [0002] In the current diamond industry, pyrophyllite blocks are generally used in half blocks, and the pressing dies are integrated hard alloy dies. In order to improve the uniformity of the temperature field during the diamond synthesis process and improve the assembly efficiency of the synthetic block, it is necessary to adopt an integrated pressed pyrophyllite block. However, with the increase of the charging chamber, the loose height of the pyrophyllite material is also increasing, and the corresponding pyrophyllite block alloy die set and the supporting upper and lower pressure heads and core rods are synchronously lengthened, and the pressing pressure and holding time are also increasing. , in such a background, the original structure of the alloy mold ...
