Technical Field

[0001] The invention relates to the technical field of nut processing, and in particular to a nut processing machine tool with a chip removal function. Background Art

[0002] Nuts are nuts, parts that are screwed together with bolts or screws for fastening. Common shapes include hexagonal nuts, square nuts, round nuts, etc. to meet different installation requirements. All manufacturing machinery must use a component. According to the different materials, they are divided into several types such as carbon steel, stainless steel, non-ferrous metals (such as copper), etc. Nuts of different materials have different performance characteristics, such as carbon steel nuts have lower cost and higher strength; stainless steel nuts have good corrosion resistance; copper nuts have good conductivity, etc. Nuts cooperate with bolts or screws to tightly fix two or more parts together through the interaction of threads to prevent loosening and separation. Nut processing machine tools are equipment specially used for processing nuts, which can perform thread processing, hole processing or shape processing on nuts; Existing nut processing machines will generate a large amount of iron chips when processing nuts. Since nut processing is a multi-step process, if the iron chips attached or accumulated on the surface of the nut after one processing are not removed in time, it will affect the quality of subsequent processing steps. Therefore, we propose a nut processing machine with chip removal function. Summary of the invention

The surface of the oblique ring scraper 304 is set as an inclined surface and the top is set as a plane. When the oblique ring scraper 304 moves upward, it scrapes and cleans the surface of the long air pipe 211.The area near the high-pressure air pump 210 is covered by setting an oblique ring scraper 304 on the outside of the long air pipe 211, and the two sides of the exhaust hole 212 are covered by setting a square baffle 306 on the plane of the oblique ring scraper 304. Small thorn blocks 307 are set on the side of the square baffle 306 to comb the hard brush 201 as the oblique ring scraper 304 moves upward. A large amount of iron filings that are cleaned and dropped fall on the annular sleeve 209. When the annular sleeve 209 rotates, the oblique scraper 403 on the top scrapes and cleans its surface, and the scraped iron filings are gradually pushed outward by the oblique setting of the oblique scraper 403. The iron filings that fall into the annular concave shell 401 are uniformly collected and processed. A deformable hard scraper 404 is arranged on the side of the inclined scraper 403 close to the high-pressure air pump 210 to scrape and clean the iron filings. The annular inclined shell 402 is arranged on the annular concave shell 401 to cover the iron filings that are continuously pushed into the annular concave shell 401. When the annular sleeve 209 rotates, the concave connecting rod 406 at the top is driven to rotate. When the concave connecting rod 406 rotates, the concave scraper 405 at the bottom is driven to rotate together. When the concave scraper 405 rotates, the inner wall of the annular concave shell 401 is scraped and cleaned at all times.
