Cutting sheet, cutting sheet processing mold and processing method

Abstract

The invention relates to a cutting sheet, a cutting sheet processing mold and a processing method. According to the cutting sheet, the cutting sheet processing mold and the processing method, powder and a bottom sheet are sintered into the cutting sheet by a pressing mold, a sintering mold and a cooling mold, specifically, the powder is pressed on the bottom sheet by the pressing mold, the powderis sintered and formed by the sintering mold, a knife particle is pressed into the designed shape by the cooling mold and through high pressure, a silver welding sheet is not needed compared with a silver welding sheet welding process, iron materials of iron, copper and the bottom sheet in metal powder of the sintering process form iron alloy, the adhesive strength of the knife particle and the bottom sheet is higher than that of the welding process, the process condition is not stricter than that of the welding process, a small amount of rust and oil dirt do not influence the product quality,the sintering process has little influence on the body health of workers compared with the welding process, the quality standard of the product can be improved by hot-pressing process, and the position, size and shape of the knife particle are guaranteed to meet the design requirement, so that the cutting sheet, the cutting sheet processing mold and the processing method are more suitable for different stone materials or ceramic tiles.

Description

technical field [0001] The application belongs to a cutting blade and a processing method thereof, in particular to a sintering machine mold and a diamond saw blade. Background technique [0002] Cutting blades for ceramic tiles or stones are usually called diamond saw blades. Diamond saw blades are made by sintering emery and metal powder, and then welding them on the base plate with silver solder. Welding needs to degrease the negative film, otherwise it is easy to cause weak welding, because when the negative film is processed by mechanical equipment, it often has organic oil, manual grease, rust, etc. In addition, the blade of the cutting blade is thin, and the temperature control during welding is not good. When the knife grain turns dark red, it means that the temperature is not enough, and the knife grain has a dazzling red light, the temperature is too high, and the temperature is low, it is not easy to weld firmly, and the temperature is too high, the metallographic...

Problems solved by technology

[0013] Powder distribution: The powder after mixing evenly needs to be pressed into knife pellets according to the specified weight, and then sintered. The single weight of diamond knife pellets or hard alloy is very small. The factory uses a tray balance to weigh the powder during processing. Put the weighed powder in the powder hole. The powder hole is the upper and lower through holes. The die-casting machine has an upper hydraulic press and a lower hydraulic press. The hydraulic column of the lower hydraulic press withstands the lower part of the distribution hole to prevent the powder from leaking. , Pour the weighed powder into the powder hole, press down the hydraulic column of the upper hydraulic machine, after the powder is pressed and formed, the hydraulic column of the lower hydraulic machine moves down, and the hydraulic column of the upper hydraulic machine continues to press down, and the pressed block The powder is withdrawn. In order to prevent the powder from contaminating the pallet, the worker needs to put a piece of paper on the pallet. After weighing it, fold the paper into a shape suitable for dumping the powder. From the above processing technology, it can be seen that the material needs to be divided by a spoon for many times. This operation, even a skilled worker needs at least two or three hand shakes to complete. Moreover, the distribution of materials is not very strict. The pointer of the tray balance can only be said to roughly return to zero. The workers frequently operate, and it is difficult to avoid contact with the powder. There are a lot of heavy metals in the powder, especially some of the formulas contain heavy metal elements such as Cd and Pb that are seriously harmful to the human body. The manual distribution of materials is inefficient and damages the health of workers.
