A processing technology of carving knife

Abstract

The invention relates to a machining technology of a graver. The machining technology comprises the following steps that A, diamond powder, nickel powder, cobalt powder and iron powder are selected according to a certain proportion and then uniformly mixed and stirred for use; B, mixed raw materials obtained in the step A are poured into a mold, the head of a graver matrix is inserted into the mold, a fixture is installed to enable the graver matrix and the mold to be fixed in a straight line, and the mold is delivered into a brazing furnace; C, a power supply of the brazing furnace is startedfor heating, the interior of the brazing furnace is vacuumized till the temperature of the brazing furnace reaches 1,020-1,050 DEG C after 10 hours, and the mixed raw materials are molten in the moldand then fused together with the graver matrix; and D, the matrix obtained in the step C is machined into a computer graver through an aqueous solution adsorption method electroplating technology. According to the machining technology of the graver, the graver adopting the dual production technologies including vacuum high-temperature brazing sintering and aqueous solution adsorption electroplating is sharp in effective grinding, the grinding time is increased by 10 times compared with the grinding time of an original product, and the machining efficiency is high.

Description

technical field [0001] The invention relates to a cutting tool processing technology, in particular to a carving knife processing technology. Background technique [0002] Engraving knives refer to various cutting-edge steel engraving tools, which are mainly used for engraving various materials. The existing engraving knives mainly use the following two processes: [0003] One is the electroplating process of aqueous solution adsorption method. Although this process has sharp grinding, it is suitable for carving stone materials of various materials. It can be plated with multiple layers to increase the grinding time, but it can only be plated on the original shape of the substrate, which is limited by the shape. And the size limit can not be plated to the ideal thickness, so the effective grinding time is short. [0004] The other is the vacuum high-temperature brazing fusion process, using which the brazing powder and diamond are clad on the surface of the cutter head with...

Problems solved by technology

[0003] One is the electroplating process of aqueous solution adsorption method. Although this process has sharp grinding, it is suitable for carving stone materials of various materials. It can be plated with multiple layers to increase the grinding time, but it can only be plated on the original shape of the substrate, which is limited by the shape. And the size limit can not be plated to the ideal thickness, so the effective grinding time is short

[0004] The other is the vacuum high-temperature brazing fusion process, using which the brazing powder and diamond are clad on the surface of the cutter head with the desired shape at high temperature in vacuum. Although the production process is protected by vacuum and the product quality is stable, it can only be used alone. Layer melting for short grinding times

[0005] It takes more than an hour for the computer engraving machine to install the engraving knife, and frequent replacement of the knife will affect production efficiency

[0006] All there are more defect problems in above-mentioned two kinds of crafts, therefore, the present invention is necessary to research and develop a kind of grinding time, the machining craft of engraving knife with long service life
