Description

Technical Field

[0001] This utility model relates to the field of automated processing, specifically to a long-distance high-speed cutting device for silicon carbide plates. Background Technology

[0002] Due to its extremely high hardness, silicon carbide sheets are very prone to cracking during cutting, leading to defects. While increasing the cutting speed has been used to address this issue, it also raises the saw blade temperature significantly. Traditional cooling water, while effective, causes further splashing and increased noise due to the higher blade speed, resulting in a poor processing environment. Furthermore, the large cutting lengths of the silicon carbide sheets used in this solution, combined with the high cutting speed and the high hardness of silicon carbide, mean that traditional positioning structures and methods often lead to cracking during the cutting process.

[0003] In view of the problems existing in the prior art, this utility model designs and manufactures a long-distance high-speed cutting device for silicon carbide plates to overcome the above defects. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a long-distance high-speed cutting device for silicon carbide plates, which can reduce water splashing and noise problems during high-speed cutting, and also reduce the occurrence of high cracking in traditional cutting.

The cutting device includes a high-speed rotating saw blade that can extend out of the cutting platform through a saw blade movement groove. The cutting device is also equipped with a water spraying device, and the nozzle of the water spraying device is directed upwards toward the top of the saw blade. A pressing support is provided above the cutting platform. Several pressure plates are evenly spaced on the pressing support along the length of the saw blade moving groove. Both ends of the pressure plates extend to the sides of the pressing support. Each pressure plate is connected to a vertical pressing cylinder at the bottom of both ends. The cylinder rod end of the vertical pressing cylinder is provided with a pressing block. The pressing block can press against the silicon carbide plate on the cutting platform. The lowering bracket is also equipped with two lifting cylinders, which are located near the two ends of the saw blade moving groove. The cylinder rod ends of the two lifting cylinders are connected to channel steel, with the groove opening of the channel steel facing downward and located directly above the saw blade moving groove. The lifting cylinders can drive the channel steel to move up and down above the saw blade moving groove.

[0006] Preferably, the two legs of the channel steel are connected to rubber flexible plates, and the lifting cylinder can drive the channel steel to descend so that the rubber flexible plates abut against the silicon carbide plate of the cutting platform.

Moreover, the downward-facing channel steel allows the cooling water to come into contact with the cutting position again under the action of gravity after hitting the bottom of the channel steel, which improves the cooling efficiency of the water. In addition, the channel steel can also play a certain role in noise reduction, improving the processing environment in the workshop.

[0015] 2.
