Plating bath for producing diamond fretsaw

Abstract

The invention relates to a plating bath for producing a diamond fretsaw, which comprises a plating bath main body, wherein a first rotating shaft and a second rotating shaft are arranged in the height direction of the plating bath main body in parallel; the bottom of the plating bath main body is provided with at least two liquid inlet pipes which are connected with an external driving pump; and the two liquid inlet pipes are arranged the first rotating shaft and the second rotating shaft in the same direction with. When in use, a metal wire is helically wound between the first rotating shaftand the second rotating shaft, and the rotation of the first rotating shaft drives the metal wire to rotate around the first rotating shaft and the second rotating shaft, so that the metal wire movesforward along the axial lines of the first rotating shaft and the second rotating shaft; and meanwhile, a plating solution is pumped to the plating bath main body, and diamond micropowder suspended in the plating solution slowly flows upwards along with the plating solution, and contacts and collides with the metal wire, thereby realizing composite sedimentation of the diamond micropowder and a metal matrix. The invention has the advantages of simple and reasonable structure, small space occupation, high production efficiency, uniform distribution of the diamond micropowder on the metal wire,controllable diamond sedimentation density and good plating quality. The produced plated diamond fretsaw has the advantages of good flexibility and high strength, is suitable for industrialized production and can replace the existing diamond fretsaw plating bath.

Description

technical field [0001] The invention discloses an electroplating tank, in particular to an electroplating tank for producing diamond wire saws. It belongs to the technical field of electroplating. Background technique [0002] Electroplated diamond wire saw is the key material for wire cutting of hard and brittle materials. Compared with other wire cutting products for cutting hard and brittle materials, it has obvious advantages such as environmental protection, low cost, high cutting efficiency, and good slice quality. The electroplated diamond wire saw must have good cutting performance. On the one hand, the diamond is required to be deeply buried in the electroplating layer on the metal wire. It has a good holding force on the diamond, and the diamond will not be easily scraped off by the cutting material during the cutting process. On the other hand, the diamond density on the metal wire is required to be high and evenly and continuously distributed. During the cutti...

Problems solved by technology

The prior art adopts electrospray plating method, brush plating method and felt plating method to produce electroplated diamond wire. The feature of these production methods is that in a short period of time, diamond is directly deposited on the metal wire at a faster speed. A very weak physical adsorption force is attached to the metal wire, and the amount of diamond attached to the metal wire is small, resulting in low density. This method of depositing diamond requires a very uniform and stable control of the process. Due to the influence of process parameters There are many factors that make the operation very difficult, resulting in non-uniform diamond deposition on the wire

In particular, the prior art usually adopts a linear electroplating method and equipment. In order to achieve the thickness of the coating, on the one hand, the length of the electroplating tank is increased by prolonging the electroplating time, resulting in a large space occupied by the electroplating process equipment; On the one hand, by increasing the current density, the deposition rate of the plated metal is accelerated; this will lead to a decrease in the quality of the electroplated layer, and the electroplated layer is prone to defects such as pores and hydrogen embrittlement, making it difficult to guarantee the quality of the electroplated diamond wire saw

Because the diameter of the metal wire used as the cathode is small and the current carrying capacity is low, when a diamond wire saw is produced with a large current density, it may cause the metal wire to be blown and affect the normal production
