Method and device for manufacturing continuous long-distance braze-welded wire saw

Abstract

The invention relates to a method and device for manufacturing a continuous long-distance braze-welded wire saw. According to the method and device, a wire is paid off through a pay-off wheel to sequentially pass through a texturing device, a washing device, a tensioning device, a straightener, a coating device, a sand applying device, a heating device, a thermal treatment device, a washing tank and a power wiring device, and then the complete manufacturing process route of the braze-welded wire saw including texturing, washing, straightening, coating, sand applying, heating and braze welding, posterior thermal treatment, washing and wire take-up is completed. The wire saw manufactured with the device is continuous, long in distance, uniform in diameter, stable in performance and capable of being used for precision machining. Meanwhile, the device is complete in function and high in automation degree, labor consumed time is greatly shortened, the manufacturing efficiency of the braze-welded wire saw is improved, and the manufacturing cost is reduced. The method and device for manufacturing the continuous long-distance braze-welded wire saw makes the braze-welded wire saw have more extensive application prospects and pushes the manufacturing application process of the braze-welded wire saw.

Description

technical field [0001] The invention relates to a production method and device of a brazing super abrasive wire saw. It belongs to the field of super abrasive tools. Background technique [0002] Hard and brittle materials such as silicon crystals, sapphire, and ceramics have the characteristics of high hardness and high brittleness, and chipping is very easy to occur during the cutting process, causing damage to the material and reducing the yield. In order to improve its processing efficiency, diamond wire saw technology is mostly used to cut hard and brittle materials. [0003] Wire saw technology enables precise, narrow kerf cuts in hard and brittle materials, as well as shaping. According to the type of abrasive particles, it can be divided into two types: free abrasive particles and bonded abrasive particles. With the continuous development of processing technology, bonded abrasive wire saws are gradually replacing Free abrasive wire saw. The main preparation metho...

Problems solved by technology

However, in actual operation, since the power is driven by three transmission wheels and lacks the tensioning device to tension the metal wire, the wire saw is easy to cause slack during the preparation, and the performance of the wire saw produced is often uneven and stable; lack of correction Straightening machine, the brazing material is applied to the metal wire, which has certain requirements for the straightness of the metal wire. It is necessary for the straightening machine to be straightened in advance, and then to coat the brazing material and super abrasive; the lack of a wire arrangement device is easy to cause The stacking of metal wires is not easy for the production of long-distance wire saws

Therefore, the performance of the brazed wire saw produced by this production line is often uneven and unstable. However, in the actual application of the current bonded abrasive wire saw, the length is required to be between 500m and 10km, and the length of the bonded abrasive wire saw is required to be between 500m and 10km. In the sawing process of semiconductor materials, the wire saw is not allowed to cut and break

Once there is a cutting break, all the cut silicon wafers have to be discarded, and the loss will reach tens of thousands, or even hundreds of thousands of yuan.
