Description
Technical Field
The invention belongs to the technical field of abrasive tool application, and particularly relates to a semi-automatic distribution device for a brazed superhard abrasive saw blade and a working method thereof.
Background
The principle of brazing the superhard abrasive tool is that the abrasive, the solder and the substrate are firmly bonded together through chemical and metallurgical reactions by using a high-temperature brazing method, so that the abrasive particles are firmly held. The existing common brazing superhard abrasive tools comprise brazing diamond saw blades, brazing alloy particle saw blades, brazing diamond grinding wheels, brazing diamond drill bits and the like. The brazing superhard abrasive saw blade has the advantages of high abrasive particle exposure, high abrasive particle holding strength, high sharpness, long service life and the like, is widely applied to the fields of metal material processing, hard and brittle non-metal material processing and the like, and successfully replaces the traditional electroplating tool in many fields. Therefore, in the next decades, by virtue of the excellent performance advantages of the brazed ultrahard abrasive saw blade, the application of the brazed ultrahard abrasive saw blade in the fields of metal material, hard and brittle non-metal material processing and the like becomes more and more extensive. In recent years, many superabrasive tool manufacturers and related research institutes in China are researching, developing and producing brazing superabrasive tools, but the problem of how to carry out industrial large-scale production on the novel superabrasive saw blade is not well solved.
Most of the current reports are related to the appearance and preparation method patents or documents of sintered or electric saw blades, related inventions and researches on brazed superhard abrasive saw blades are few, most of the related inventions and researches only relate to the design of the appearance structure of the brazed superhard abrasive saw blade or the introduction of the preparation method of the brazed superhard abrasive saw blade, and little relates to how to stably prepare the brazed superhard abrasive saw blades in batches. The preparation process of the brazing saw blade mainly comprises three main processes of pre-welding treatment, material distribution, brazing and the like, wherein the pre-welding treatment and the brazing process can be automatically completed in batches by using related equipment, and for the material distribution process, the preparation process of a single saw blade is greatly different from the preparation method of batch production, the preparation method of the single saw blade cannot be simply assembled and then produced, and related series of design and invention are required to be created by combining the preparation characteristics of the brazing abrasive material superhard saw blade. Because related enterprises and research units have less research on the aspect, the distribution production of the saw blades still adopts manual and semi-manual labor-intensive operation modes, and the large-batch automatic production equipment and method still have certain market gaps at present.

The patent (CN 102896387B) relates to a brazing superhard abrasive material distribution process, which utilizes the bonding effect of a bonding agent, adopts the bonding agent coating, diamond distribution and welding flux to prepare a brazing superhard abrasive material tool, the method has certain universality, but the process is not specific and prepared for saw blade tools with rotation symmetry, the coating of the bonding agent is not easy to prepare and standardize, and the batch application of the bonding agent to the preparation of superhard abrasive material saw blades not only needs to research and develop a preparation device, but also needs to fundamentally improve the distribution process.
