Design method of scraper fast passing principle

The principle of designing scraper is mainly to scrape off impurities or skins on the surface of objects by using the friction between blades. Here are some ways to design a scraper:

1. material selection: select the appropriate material for the blade part of the scraper. Common materials are stainless steel, ceramics and high carbon steel. These materials have good hardness and wear resistance.

2. Blade angle: The blade of the scraper should have an appropriate angle. A blade that is too straight may not scrape off impurities effectively, while a blade that is too inclined may cause unnecessary damage. According to needs, we can choose different knife-edge angles to adapt to different application scenarios.

3. Sharpness of the blade: The blade of the scraper should be sharp enough to ensure that it can cut into the surface of impurities more easily when scraping impurities. Common grinding methods include grinding stone or professional tools grinding equipment.

4. Handle design of LHD: The handle design should conform to the principle of ergonomics, making it more comfortable and stable to use. The material of the handle should also have good grip performance to avoid sliding.

It should be noted that care should be taken when using the scraper to avoid injury. If you need to design a scraper in a specific field, it is recommended to consult a professional designer or engineer for more detailed and personalized advice.
