Screw insulating device for six-surface top press

Abstract

The invention relates to the technical field of insulation, in particular to a screw insulating device for a six-surface top press. The screw insulating device for the six-surface top press comprisesa six-surface top press screw, a protective cover body and a protective top cover; a diassembling hole is formed at the center position of the upper surface of the protective top cover; the protectivecover body comprises a first semi-cylindrical protective cover and a second semi-cylindrical protective cover; and the protective cover body is formed by mutually embedding the first semi-cylindricalprotective cover and the second semi-cylindrical protective cover. The connecting screw can be integrally protected through cooperation of the protective cover body and the protective top cover, particularly comprehensive closed protection on the screw head can avoid shortcircuit of the screw head by metal foreign body lapping; through cooperation of multiple groups of embedded teeth and cavities, the stress generated when the six-surface top press works can be effectively dispersed, so that the service life of an insulating device is prolonged; meanwhile, the insulating device adopts an integrated structure, so that the problem in the traditional insulating structure that a screw rod insulating sleeve is taken out of a big cushion block difficultly after being stressed to deform is solved and accessories are convenient to change.

Description

technical field [0001] The invention relates to the field of insulation technology, in particular to a screw insulation device for a six-sided press. Background technique [0002] The six-sided top press is a kind of equipment specially used to produce superhard material products. It generates high pressure through hydraulic pressure, and applies low voltage and high current to both ends of the synthesis block to generate high temperature, so as to provide the required energy for the synthesis of superhard materials. Pressure and temperature, generally speaking, the heating system of the six-sided top press is a heating circuit composed of a power supply, a transformer, copper braid, a large spacer, a small spacer, an anvil and a synthetic block in series. In industrial production, Guaranteeing the closure and stability of this heating circuit is crucial to the production of high-quality products; [0003] Since the cylinder of the six-sided top press is a conductor, it is ...

AI Technical Summary

Problems solved by technology

[0003] Since the cylinder of the six-sided top press is a conductor, it is required to maintain good insulation between the heating circuit and the cylinder. In the insulation circuit, the large pad is connected to the cylinder through connecting screws. People usually use the large pad Add a layer of insulation board between the cylinder body and use insulation gaskets and sleeves to isolate the connecting screws for insulation treatment. However, the commonly used screw insulation device does not protect the screw head. It may be short-circuited due to the overlapping of metal foreign objects. In addition, because the pressure of the six-sided top press is extremely high during operation, the connecting screws between the large spacer and the cylinder are also subject to high pressure, so the insulating sleeve outside the screw is susceptible to damage. If the force is damaged, the insulation capacity will be reduced, and even leakage will occur. Moreover, the damaged sleeve will be deformed, and it will not be easy to take it out from the screw hole, which will increase the difficulty of replacing the insulating parts.
