Description

Technical Field

[0001] This utility model relates to the technical field of diamond wire saw production equipment, specifically to a diamond wire saw drying device. Background Technology

[0002] Diamond wire saws are wire cutting tools made by electrochemically depositing diamond abrasive onto the surface of steel wire. They are used to cut brittle and hard non-metallic materials such as silicon wafers, sapphire, magnetic materials, semiconductors, glass, and stone.

[0003] Currently, the final step in the production line of diamond wire saw manufacturing equipment is drying, which evaporates the moisture on the surface of the steel wire to reduce rusting caused by moisture. However, almost all diamond wire saw equipment currently uses an oven for drying before winding the wire onto the take-up reel to become the finished product. This online drying method has the following problems:

[0004] The drying oven is relatively short, typically less than 1.5 meters, while the production speed is usually above 20 m / min. This means the steel wire only spends about 4.5 seconds in the oven. To achieve the desired drying effect within such a short time, the oven temperature needs to be set to around 250℃. The oven's power is only 2 kW, resulting in extremely low heat utilization and high energy consumption. While the diamond wire saw is dry in the oven for a short time, it absorbs moisture from the air after reaching the take-up reel, leading to re-dampening, especially in humid areas. If the steel wire runs on the take-up reel for more than 6 hours, it may become damp and rust again. This is particularly problematic in summer when the finished steel wire requires secondary drying, resulting in significant energy waste. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a diamond wire saw drying device to improve the drying efficiency of diamond wire saws.

[0006] To achieve the above and other objectives, this utility model is implemented through the following technical solution: This utility model provides a diamond wire saw drying device, the diamond wire saw drying device comprising: a fan, the fan including a first air outlet; an air duct, one end of the air duct being connected to the first air outlet; a cover having a cavity, the cover having an air inlet and a second air outlet at both ends, the air inlet being connected to the other end of the air duct; a heater disposed within the cavity; and a thermocouple, at least partially located within the cavity.

[0007] This utility model provides a drying device for diamond wire saws. Compared with the prior art, this utility model has the following beneficial effects: the power of the drying device for diamond wire saws in the prior art is mostly 2kw, while the drying device of this utility model has a power of 0.2kw for the fan and 0.4kw for the heater, totaling 0.6kw, saving 1.4 kWh of electricity per hour and about 10,000 kWh of electricity per production line.

[0008] Existing drying devices heat the wire saw for only about 4.5 seconds. After the steel wire reaches the take-up reel, it will be affected by moisture in the air, causing it to become damp and some of the wire to rust. However, the drying device of this invention can continuously blow hot air onto the take-up reel, ensuring that the diamond wire saw is in a continuously dry state and is not affected by the humid environment.
