Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the lack of strength of the abrasive tools in the prior art, it is easy to break under the action of centrifugal force during high-speed rotation, causing potential safety hazards. At the same time, a large amount of heat generated during the grinding process of the abrasive tools cannot be removed in time. Seriously affect the grinding efficiency of the abrasive tool, a kind of optical glass production abrasive tool and its preparation method proposed by the present invention

preparation example Construction

[0030] A method for preparing an abrasive tool for optical glass production, the preparation method is suitable for preparing the above-mentioned optical glass production abrasive tool, comprising the following steps:

[0031] S1. Weighing the diamond powder and the binder according to the corresponding ratio, and then crushing and grinding the binder to obtain the binder powder;

[0032] S2. Put the diamond powder and the binder powder into the mixer and stir evenly. At the same time, add the corresponding proportion of corundum and processing aids to the mixer, mix for 5-10min, and heat the stirring equipment at the same time. The heating time is 20- 30min, heating at 80-100°C to obtain dry mixture A, then seal and store mixture A for later use;

[0033] S3. Mix carbon steel powder and kaolin powder and dry them to obtain a raw material mixture B of the sacrificial layer 16;

[0034] S4. Preheat the molding equipment used to produce abrasive tools. When the temperature reac...

Embodiment approach

[0037] As an embodiment of the present invention, a temperature measuring hole 42 is opened at the bottom of the cavity 36, and a mounting plate 43 is fixedly connected to the temperature measuring hole 42, and a U-shaped copper wire 44 is arranged at the bottom of the mounting plate 43, and the copper wire 44 Both ends are connected to the controller through wires, and the heating device is controlled after the copper wire 44 is fused to improve the production efficiency of the abrasive tool; Sensing the internal temperature of the abrasive powder raw material, when the copper wire 44 melts, an open circuit is formed, and then the controller controls the heating device to stop the temperature rise, while ensuring the heating speed of the mold cavity 31 and reducing the overheating of the mold cavity 31, so that the abrasive tool is powdery The temperature of the outer and core of the raw material is uniform, which increases the sintering quality of the abrasive tool and improv...

Abstract

The invention belongs to the technical field of an abrasive tool, in particular to an optical glass production abrasive tool and a preparation method thereof. The optical glass production abrasive tool comprises a cylindrical grinding layer, and multiple layers of strengthening nets are arranged in the grinding layer. An arc-shaped groove is formed in the grinding layer and is matched with the surface profile of a lens to be ground. A group of heat emission holes are uniformly distributed in the circumference of the top of the grinding layer, and the positions, corresponding to the heat emission holes, of the strengthening nets are fixedly connected with lantern rings. The periphery of each lantern ring is fixedly connected with a group of wavy vibrating wires. By the multiple layers of strengthening nets arranged in the grinding layer, the strength of the abrasive tool is increased, the damage of the abrasive tool during grinding at high speed rotation is reduced, further the abrasivetool has a higher rotating speed limit, and the grinding efficiency of the abrasive tool is improved. Meanwhile, the vibrating wires rapidly transfer the heat generated during the working of the abrasive tool to the heat emission holes by the heat transfer property of metal, so that the heat emission performance of the abrasive tool is increased, and the normal working of the abrasive tool is ensured.

Description

technical field [0001] The invention belongs to the technical field of abrasive tools, in particular to an optical glass production abrasive tool and a preparation method thereof. Background technique [0002] Abrasives are tools used for grinding, grinding and polishing. Most of the grinding tools are artificial grinding tools made of abrasives and bonding agents, and natural grinding tools are also directly processed into natural ore rocks. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of non-metallic materials such as grain processing, paper industry, ceramics, glass, stone, plastic, rubber, and wood. [0003] Optical glass is a glass that can change the direction of light propagation and change the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass in the narrow sense refers to colorless optical glass; optical glass in the broad sense...
