Description

A device for protecting blade from impact during cutting

Technical Field

The utility model relates to the technical field of blade protection devices, in particular to a blade anti-collision protection device during tool cutting.

Background Art

When a desktop cutting machine is in use, the blade protection groove plays a role in protecting the cutting machine blade from impact. The cutting machine protection groove is a device used to protect the cutting machine blade and the operator's safety. It is usually installed on the working table of the cutting machine to prevent workpiece fragments from splashing and the operator from contacting the blade. The protection groove is usually made of metal material with durability and impact resistance. They are designed to match the cutting machine blade to ensure that the blade can operate normally during the cutting process and avoid any potential dangers.

Existing cutting machines will generate a large amount of debris when cutting pipes or other materials. Some of the debris will adhere to the inner walls on both sides of the blade protection groove. When there are too many debris attached to both sides of the blade protection groove, the cutting blade is likely to come into contact with the debris during cutting, and the debris will rub against the rotating cutting blade, affecting the service life of the cutting blade.
