Hardware fitting handheld cutting device based on scrap diversion and use method thereof
Technical Field
The invention relates to the technical field of hardware fitting cutting devices, in particular to a hardware fitting handheld cutting device based on scrap diversion and a use method thereof.
Background
Hardware fittings are an important class of parts that are widely used in industrial manufacturing, including screws, nuts, washers, fasteners, bearings, and the like. In the production process, cutting, trimming or machining operations are sometimes required to meet specific requirements.
The hardware fitting handheld cutting device of the prior art has the following defects:
due to the small volume of the scraps, the scraps are difficult to be perceived and cleaned by eyes in time after being cut. Especially in a closed workplace, scraps are easy to spread to all corners of the workplace and are difficult to clean; the small volume of debris has little resistance to the fluid (e.g., air) and once created is easily dispersed with the fluid. Cutting in a working environment such as a laboratory or workshop, the scraps can spread along with air flow quickly, and pollute the whole working area; cleaning small volumes of debris using conventional tools such as brushes and the like is also inconvenient. The brush does not clean very well the small scraps that adhere to the difficult-to-reach areas, and may also directly migrate them instead of clean them; when the hand-held method is used for processing the micro hardware, the sight line state is required to be good. But tiny scraps can easily enter eyes, mouths and noses of workers after being generated, and the working quality and the health are affected.
In view of the above, there is an urgent need for a handheld cutting device for scrap-guided hardware and a method for using the same to solve the deficiencies of the prior art.
