Abstract

The invention belongs to the field of the forging and forming of the large forging and particularly relates to a forging and forming method of an integral hinge beam in a cubic press used for ultra-high pressure synthesis. A steel ingot is heated to the initial forging temperature according to the heating specification, wherein, reheating according to the heating specification during each work procedure is needed, and the initial forging temperature is not lower than 900 DEG C; after the steel ingot is upset to have the height-diameter ratio of 1, the billet is upset by using a swage into a round disc with an inclined surface at the bottom; after the round-disc shaped billet is drawn out into the cross-shaped billet, tong handles are cut off, a central hole is punched, and the billet is mechanically processed. Due to the adoption of the forging and forming method of the integral hinge beam, the problem on the central compaction of the hinge beam in the forging process is solved, the performance of the product is improved, the service life of the product is prolonged, the process of forging for producing is simplified, the utilization rate of the steel ingot is improved, the production efficiency is enhanced, and the production cost is reduced.

Description

technical field

[0001] The invention belongs to the field of forging and forming of large forgings, and in particular relates to an integral hinge beam forging and forming method in a six-sided top press for ultra-high pressure synthesis. Background technique

[0002] There are three main types of synthetic equipment used in the field of synthetic diamond synthesis: annual ring type double-sided pressing machine, concave mode double-sided pressing machine and six-sided pressing machine. Europe, America, Japan and South Korea mainly use annual ring double-sided presses, and Russia and the Commonwealth of Independent States mainly use concave double-sided presses. The feature of the double-sided top press is that it can produce high-quality diamonds, and the production technology is relatively mature, but the mold manufacturing cost is high and the production technology is complicated. The six-sided top press is equipment with independent intellectual property rights in China...
