Problems solved by technology

In order to improve cutting efficiency, sandwich and multi-sandwich structure cutter heads have been developed in the prior art. Compared with ordinary block cutter heads, this kind of cutter head has increased the free surface of brittle hard non-metallic materials such as stone to be sawn, making It is easier to break the stone, which improves the sharpness of sawing, thereby improving the cutting efficiency, and at the same time reduces the power consumption and lowers the cost of sawing. Due to the unbalanced force on the center and outer diamond layers, the cutting stability needs to be improved, and for the stone cutting process, the consumption of diamond saw blades occupies more costs, so it is also necessary to further improve the use of diamond saw blades. life

preparation example Construction

[0029] The preparation method of the energy-saving and high-efficiency diamond saw blade of the present invention is as follows:

[0030] 1. According to the requirements of the drawings, the steel plate is quenched and heat treated, tempered, laser cut into shape, tempered, plane ground, inner hole ground, outer circle ground, and deburred to make a circular steel substrate.

[0031] 2. Mix the carcass powder and diamond particles uniformly and cold-press to form and cold-press into a diamond blank in the middle and diamond blanks on both sides, and combine the diamond blank in the middle and the diamond blanks on both sides with the The metal blank layer forms a laminated structure according to the order and is hot-pressed and sintered, and the grinding wheel and abrasive belt are ground to make a composite multi-layer diamond cutter head. The temperature of hot-pressing sintering is 725-800 °C, and the pressure is 250-300kg / cm 2 , The holding time is 150-250 seconds.

Abstract

The invention relates to an energy-saving efficient diamond sawblade, and belongs to the technical field of diamond sintering tools. The energy-saving efficient diamond sawblade comprises a circular steel base body, and a compound multi-layer diamond cutter head which is welded on the circular steel base body, wherein the compound multi-layer diamond cutter head comprises a plurality of diamond cutting layers, and each multi-layer diamond cutting layer comprises a blank body, and diamond particles which are embedded into the blank body; the concentration of the diamond particles in the intermediate diamond cutting layer is more than the concentration of the diamond particles at two sides; and the hardness of the blank body in the intermediate diamond cutting layer is less than the hardnessof the blanks in the diamond cutting layers at two sides. The energy-saving efficient diamond sawblade is applicable to processing of stones such as granites and marbles and cutting of a concrete pavement; the energy-saving efficient diamond sawblade has the characteristics of being quick to cut, high in cutting sharpness, and stable in performance; and moreover, the energy consumption can be decreased; in addition, the used diamond includes a little or excludes rare Co element and other components, so that the tool cost is decreased.

Description

technical field [0001] The invention relates to the technical field of diamond sintered tools, more specifically, the invention relates to an energy-saving and high-efficiency diamond saw blade and a preparation method thereof. Background technique [0002] Since the United States G.E. Company began to synthesize artificial diamonds in 1953, the types and specifications of diamond tools used by humans have been greatly developed. Since my country successfully synthesized artificial diamonds in 1963, my country's diamond tools have experienced from scratch, from small to large. , from decentralized to intensive, from product to industry development path. In terms of diamond tools for processing hard and brittle non-metallic materials, my country has become a major producer in the world. Diamond saw blades, diamond drill bits and diamond grinding wheels are the three main varieties of diamond tools. Among them, diamond saw blades are the leading products in diamond tools. Acco...
