Device and method for abrasive material multilayer orderly arraying

Abstract

The invention relates to a device for abrasive material multilayer orderly arraying. The device comprises a cavity where positive pressure or negative pressure can be formed. The cavity is defined by a cylinder sleeve above and a partitioning plate at the bottom end. Through holes which are arrayed in sequence are formed in the partitioning plate. Sucking pipes are fixedly connected into the through holes. The top ends of the sucking pipes are placed in the cavity. The bottom ends of the sucking pipes penetrate out to the position below the partitioning plate. The invention further relates to an orderly arraying method of the device. After the sucking pipes adsorb abrasive particles, the abrasive particles are placed into metal matrix powder, the sucking pipes can be arrayed in sequence in advance in the partitioning plate so that the abrasive particles can be arrayed in a certain plane in the metal matrix powder in sequence, the inserting depth of the sucking pipes in the metal matrix powder can be adjusted according to needs, accordingly, the abrasive particles can be arrayed in a multilayer mode from inside the outside in the metal matrix powder, and the device and the method can be used for carrying out multilayer orderly arraying on abrasive materials quickly and conveniently. The method and the device can be used for multilayer orderly arraying of the abrasive particles.

Description

technical field [0001] The invention relates to the field of manufacturing abrasives, in particular to a device and method for orderly arranging multiple layers of abrasives. Background technique [0002] In conventional superhard material tools, abrasives are randomly distributed / disorderly arranged in the matrix, so segregation is easy to occur. In the abrasive particle enriched area, the abrasive particle concentration is high, the sawing force is small, and it is easy to be polished and worn, which cannot be effectively used and wasted. At the same time, it is easy to block and hinder the removal of cuttings, resulting in a decrease in grinding efficiency; , due to the excessive workload and high impact force, the abrasive grains are easy to break and fall off. Although full mixing and granulation processes are often added to abrasive tool manufacturing, they cannot fundamentally solve the problem. In recent years, many attempts have been made on the orderly arrangemen...

AI Technical Summary

Problems solved by technology

However, the problem with the template method is that the blanking position is disordered, the arrangement is not neat, and it is not suitable for large-scale production.

[0005] In addition, people also use laser brazing method, one-time use shell mold cloth method, screen extrusion method, leakage method, screen printing, open dispersion, photolithography and matrix structuring method, etc., to arrange abrasives in an orderly manner. cloth for research experiments, but none of them can meet the needs of industrial production
