The connection device between the steel ring of the six-sided top diamond synthetic press and the large spacer

Abstract

The invention relates to a device for connecting a steel ring of a six-sided top diamond synthetic press and a large spacer. The device includes an anvil, a large spacer and a steel ring connected between the two. The large spacer includes a lower end The connecting column head connecting the base and the upper end is provided with N positioning grooves uniformly distributed along the circumferential direction on the side of the connecting column head, and the upper part and the lower part of the steel ring are respectively provided with a stepped upper installation hole and a lower installation hole. The upper mounting hole is a tapered hole whose inner diameter gradually decreases from the inside to the outside. The upper mounting hole is coaxially installed with a top hammer that matches it and extends out of the hole. The steel ring is coaxially sleeved on the large spacer through the lower mounting hole. Connect the column head and fix the two relatively through the jacking wire. The inner end surface of each jacking wire is installed with a spherical ball protruding from the end surface through a spherical pair, and each ball is pressed against the positioning groove at the corresponding position. The invention precisely controls the concentricity of the steel ring, the large cushion block and the top hammer, improves the quality of the pressed product, and reduces the times of hammer calibration.

[0002] The six-sided top diamond synthetic press is the most widely used special heavy equipment in the superhard material manufacturing industry in China. It uses oil pressure to push the six-cylinder piston as the pressure source, and the pressure is transmitted to the upper, lower, left, and The hammer heads in the six directions of right, front and rear are then transferred to the material. During the diamond synthesis process, the hydraulic press is in a state of high temperature and high pressure, which can easily cause the hammer surfaces of the hammer heads to be non-parallel, making the confluence of the six top hammers The center of force shifts and cannot converge on the center point, which makes the deformation of the high-pressure chamber inconsistent, which not only reduces the service life of the top hammer, but also affects the quality of the product. Therefore, the six-sided top diamond synthesis press needs to perform the top hammer before diamond synthesis Correction, however, in the prior art, the anvil is connected to the large block through a steel ring, the gap between the steel ring and the large block is large, and the steel ring is clamped on the large block with a top wire, and the bottom of the top wire is larger The flat contact surface of the flat head, when the pressing force is large, it is easy to cause the large pad to be crushed, and the uneven tightening force will also cause eccentricity. At the same time, the gap between the steel ring and the top hammer is large. When the six top hammers meet, the top hammer will If it is loose, the pressing forces of the six anvils cannot converge at the center point when pressing, and eccentricity will occur, requiring frequent corrections of the anvils, which is cumbersome, time-consuming and labor-intensive to operate, and increases the labor intensity of the workers. Reduce its production efficiency and affect the quality of products
