Wherein, the reinforcing section 1 is tubular, two liquid inlets 11 and an overflow port 12 are arranged on the side wall of the reinforcing section, the overflow port 12 is positioned at the position 5mm of the upper edge of the reinforcing section, and the liquid inlet 11 is positioned below the overflow port 12 and close to the bottom of the reinforcing section 1. The overflow port 12 on the strengthening section is connected with the plating solution tank 5 through a pipeline, so that redundant plating solution returns to the plating solution tank 5 for storage, the plating solution in the plating solution tank 5 returns to the strengthening section 1 and the sand blowing tank 7 through liquid inlets 11 respectively by the filter pump 6, and the sand blowing tank 7 is connected with a sand blowing liquid inlet 31 on the sand blowing section 3 through a pipeline.
Because the invention carries on the sand feeding in the vertical direction, therefore need to utilize the height of the blowing sand box 7 to provide the stable blowing sand pressure, thus guarantee the emery dispersion degree of the sand feeding section 2; the adjustment of the dispersion degree of the diamond grains can be very easily realized by adjusting the flow meter on the pipeline between the sand blowing box 7 and the sand blowing liquid inlet 31, so that the sand feeding amount of the diamond wire saw can be controlled.
The bottom of the reinforcing section 1 is connected with the inverted cone-shaped sand feeding section 2 through a flange, and the inner diameter of the interface of the reinforcing section and the inverted cone-shaped sand feeding section is the same. The anode 13 passes through the reinforcing section 1 and reaches the middle part of the upper sand section 2, and the bottom of the upper sand section 2 is filled with carborundum 9.
As shown in figure 2, the bottom of the sand feeding section 2 is connected with the sand blowing section 3 through a flange, the sand blowing section 3 consists of a sand blowing area 34, a transition area 33 and a buffer area 32, the bottom of the sand blowing area 34 is connected with the transition area 33 with the inner diameter of 5mm in an inverted cone shape, the inner diameter of the buffer area 32 is larger than that of the sand blowing area 34 to form a cavity, and sand blowing liquid inlets 31 are formed in opposite positions of two sides of the inner wall of the buffer area 32.
As shown in fig. 3, the bottom of the sand blowing section 3 is connected with the inlet line section 4 through a flange; the inlet line segment 4 comprises a sand discharge port 42, a line inlet 44 and a compaction plug 43, wherein the sand discharge port 42 and the line inlet 44 are connected below the buffer area 32, and the sand discharge port 42 is obliquely arranged; a compression plug 43 is arranged at the bottom of the wire inlet section 44, and an elastic rubber plug 41 is arranged between the compression plug 43 and the wire inlet hole 44.

(1) the speed of the steel wire 8 through the sanding section 2 determines the amount of sanding in the diamond wire saw, which is typically maintained at 5-8 m/min.
(2) The circulation speed of the plating solution determines the temperature of the plating solution and the sand content in the plating solution, and the low circulation speed can cause the local component difference of the plating solution to be increased and the temperature to be reduced, thereby influencing the electroplating effect; therefore, when the plating solution flows into the liquid inlet, the flow rate is as slow as possible, and the flow rate is as large as possible.
(3) The sand loading amount of the diamond wire saw is controlled by controlling the suspended density degree of the carborundum through adjusting the flow rate of the sand blowing liquid inlet 31, and the flow rate is generally set at 20-40mL/min
