Description

Technical Field

[0001] The invention belongs to the technical field of diamond wire saw manufacturing, and in particular relates to a high-efficiency and high-speed diamond wire saw manufacturing device and a manufacturing method. Background Art

[0002] In the prior art, the production speed of diamond wire saw varies from 10 to 30 meters per minute. Under this production process, the amount of diamond put into the machine is large, the line speed is low, and the production efficiency is low. In the prior art, the concentration of nickel-plated diamond particles in the plating solution is about 3000-5000 particles / ml. Due to the high concentration of diamonds in the plating solution, the diamonds and the inside of the pump body are seriously collided and worn, thus affecting the life of the nickel-plated diamonds and the pump. In addition, the violent collision of diamonds can easily cause the nickel layer of the surface coating to fall off, which directly leads to insufficient bonding between the diamond and the intermediate nickel layer of the busbar, thereby affecting the holding force of the diamond on the busbar. Insufficient diamond holding force can easily cause the diamond to fall off during the cutting of silicon materials, resulting in serious poor cutting and even wire breakage of the diamond wire saw. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide an efficient and high-speed diamond wire saw manufacturing device and manufacturing method, which can increase the production efficiency of traditional wire saws from 10-30 meters / minute to 90 meters / minute, and ensure that diamond particles can be evenly and effectively attached to the surface of the diamond busbar.

[0004] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: a high-efficiency and high-speed diamond wire saw manufacturing device, comprising an upper sand trough containing diamond plating solution, wherein the nickel-plated diamond particles in the plating solution of the upper sand trough are plated on the diamond busbar by an electrochemical process; the inlet and outlet ends of the upper sand trough are respectively equipped with magnetic wheels made of magnetic conductive materials, and the diamond busbar passes through the upper sand trough and is wound on the magnetic wheels; strong magnetic blocks are respectively installed on the outer sides of the two magnetic wheels, and the magnetic field formed by the strong magnetic blocks is distributed on the magnetic wheels to act on the diamond busbar. Under the action of the magnetic field, the nickel-plated diamond particles in the plating solution are quickly, effectively and evenly adsorbed and plated on the diamond busbar.

[0005] As a preferred technical solution, the magnetic conductive wheel is a solid metal wheel, preferably a stainless steel wheel.

[0006] As a preferred technical solution, the nickel-plated diamond particles are double-layer nickel-plated diamond particles, one layer is a chemical nickel-plated layer, and the other layer is an electroplated nickel layer.

[0007] The method for manufacturing an efficient and high-speed diamond wire saw comprises the following steps:

[0008] Step 1: The diamond busbar enters the upper sand trough after degreasing, water washing, pickling, water washing and pre-plating from the wire-laying machine;

[0009] Step 2: When the diamond busbar passes through the upper sand trough, the nickel-plated diamond particles in the plating solution of the upper sand trough are plated on the diamond busbar by an electrochemical process. At the same time, the effective magnetic field formed by the strong magnetic block on the magnetic wheel acts on the diamond busbar. Under the action of the magnetic field, the nickel-plated diamond particles in the plating solution are quickly, effectively and evenly adsorbed and plated on the diamond busbar.

[0010] Due to the adoption of the above technical solution, the present invention has at least the following beneficial effects: by acting on the diamond busbar with N and S magnetic fields, the diamond particles are allowed to evenly and effectively adhere to the surface of the diamond busbar when the diamond busbar moves rapidly, thereby producing diamond wire saws with high efficiency and quality.

[0011] The present invention can reduce the nickel-plated diamond particles from 3000-5000 particles / ml to 500-1000 particles / ml. The reduction in particle concentration reduces mechanical friction and collision of diamonds in the pump, thereby extending the service life of the nickel-plated diamond and the pump. The nickel layer on the surface of the nickel-plated diamond is extended to fall off, thereby extending the service life of the plating solution, thereby obtaining a nickel layer with better density, which not only improves the quality of the diamond wire saw - allowing the nickel-plated diamond to be better held on the diamond busbar through the bonding force of the medium nickel layer, but also greatly reduces the manufacturing cost. This method is more advantageous in replacing the traditional wire saw manufacturing process, and the maximum wire speed can reach 90 meters / minute, greatly improving the production efficiency of the wire saw.

In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0021] like Figures 1 to 7 As shown, the high-efficiency and high-speed diamond wire saw manufacturing device comprises an upper sand trough 1 containing a diamond plating solution, and the nickel-plated diamond particles in the plating solution of the upper sand trough 1 are plated on the diamond busbar 2 by an electrochemical process. The upper sand trough and the electrochemical plating technology are prior arts and will not be described in detail here.

[0022] The improvement lies in that the inlet and outlet ends of the upper sand trough 1 are respectively installed with magnetic wheels 3, the magnetic wheels 3 are solid structures made of stainless steel 316, and 30 U-shaped grooves are processed on the outer peripheral side; the diamond busbar 2 passes through the upper sand trough 1 and is wound around the magnetic wheels 3; the outer sides of the two magnetic wheels 3 are respectively installed with strong magnetic blocks 4, and the magnetic fields formed by the strong magnetic blocks 4 are distributed on the magnetic wheels 3 so as to act on the diamond busbar 2. Under the action of the N and S magnetic fields, the nickel-plated diamond particles in the plating solution are quickly, effectively and evenly adsorbed and plated on the diamond busbar.

[0023] refer to Figure 6 The nickel-plated diamond particles 5 include bare sand 51 with a diameter of 6-12 um. The bare sand 51 is covered with a nickel-plated layer 52. The nickel-plated layer 52 is formed by double-layer nickel plating, one layer is a chemical nickel-plated layer, and the other layer is an electroplated nickel layer.

[0024] refer to Figure 1 , a high-efficiency and high-speed diamond wire saw manufacturing method comprises the following steps:

[0025] Step 1: The diamond busbar 2 is degreased, washed, pickled, washed and pre-plated from the pay-off machine and then enters the upper sand trough 1;

[0026] Step 2: When the diamond busbar 2 passes through the upper sand trough 1, the nickel-plated diamond particles in the plating solution of the upper sand trough 1 are plated on the diamond busbar by an electrochemical process. At the same time, the effective magnetic field formed by the strong magnetic block 4 on the magnetic wheel 3 acts on the diamond busbar 2. Under the action of the magnetic field, the nickel-plated diamond particles in the plating solution are quickly, effectively and evenly adsorbed and plated on the diamond busbar 2, and the distribution of the nickel-plated diamond particles is more effective and uniform. Figure 6 .

[0027] Compared with the traditional wire saw manufacturing process, this process can greatly improve production efficiency. The wire speed can be increased from 10-30 meters / minute to 90 meters / minute, and the nickel-plated diamond particles in the plating solution can be reduced from 3000-5000 particles / ml to 500-1000 particles / ml. This efficient and high-speed diamond wire saw process is easy to operate, saves costs, can well guarantee product performance, and meet usage requirements.
