Description

Technical Field

[0001] The invention relates to the technical field of diamond wire production, in particular to an upper sand trough for producing electroplated diamond wire. Background Art

[0002] Diamond wire is the abbreviation of diamond cutting wire, which is used as a cutting tool for cutting hard and brittle materials such as single crystal silicon and sapphire. Diamond wire is mainly composed of a busbar (generally high carbon steel wire or doped tungsten wire, etc.), diamond powder and nickel plating. It is a linear superhard material cutting tool made by depositing a layer of metal nickel on the busbar substrate by electroplating. The metal nickel layer is wrapped with diamond powder, so that the powder is consolidated on the busbar substrate. In the manufacturing process of diamond wire, sanding is a key step to evenly consolidate the diamond powder particles on the busbar, which directly determines the cutting performance and life of the diamond wire.

[0003] Before sanding the diamond wire, the metal busbar must be cleaned to remove oil and rust to ensure that the electroplating layer can be evenly and firmly attached to the busbar. The existing diamond wire sanding and cleaning are usually carried out separately, which requires a lot of equipment; secondly, when the diamond wire is sanded and output, its surface is prone to carry some raw materials (electroplating solution and diamond powder), resulting in a waste of raw materials, increasing costs, and affecting the subsequent processing of the diamond wire. The diamond wire sanding device currently on the market does not have a structure for recovering the raw materials on the surface of the diamond wire, which needs to be improved.

Two vertical plates 7 are symmetrically fixed to the top of the cleaning tank near the electroplating tank side, and a nozzle 8 is installed between the two vertical plates 7. A plurality of nozzles 9 are installed at the bottom of the nozzle 8. A plurality of through holes 2 for passing the diamond wire 3 are opened on the upper part of the partition 4, and a wiper block 11 sleeved on the outside of the diamond wire 3 is provided at the through hole 2 located on one side of the cleaning tank. The wiper block 11 is connected to the partition 4 by an adhesive, and a conical groove is opened in the middle of the wiper block 11, and the diameter of the smaller end of the conical groove is equal to the diameter of the diamond wire 3.

[0028] An appropriate amount of cleaning liquid is added into the cleaning tank, and the lower part of the diamond wire 3 can be immersed in the cleaning liquid through three guide rollers 5. The motor 10 drives the two cleaning brushes 6 to rotate to clean the surface of the diamond wire 3. Most of the water carried on the surface of the diamond wire 3 is scraped into the cleaning tank through the wiper block 11 to reduce the impact on the later electroplating.
