Integral advancing scraping and rolling compound cutter for flexibly boring, scraping and rolling

Abstract

The invention discloses an integral advancing scraping and rolling compound cutter for flexibly boring, scraping and rolling. A scraping head, a boring head and a rolling head are integrated, and scraping and rolling processing are performed during advancing. The integral advancing scraping and rolling compound cutter is simple in overall structure, is convenient to manufacture, and is low in cost; high-accuracy size and shape control and good guidance can be realized, scraping becomes smoother, and wave marks and errors on a processing surface of an inner hole in a previous procedure can be eliminated, so that a completed surface becomes smoother, and a better surface profile is formed; and moreover, a plurality of processing procedures are completed continuously, so that processing time is saved.

Description

technical field [0001] The invention relates to the technical field of composite cutters in daily necessities, in particular to a composite cutter of the flexible boring, scraping and rolling type integrated scraping and rolling. Background technique [0002] With the development of social technology, further improvement of production capacity has become the focus of everyone's consideration, especially in the field of metal cutting, which requires high metal processing efficiency and high surface quality, so general cutting tools do not have the above two Square effect, such as boring cutter, rolling cutter and the like, its structure is relatively simple, and work efficiency is comparatively low. [0003] When the existing boring tool and scraper scrape and grind the metal inner wall, the metal inner wall often has some roughness that affects the smoothness. Therefore, the hob needs to be reprocessed to remove these roughness. This requires two steps to complete, which is...

[0002] With the development of social technology, further improvement of production capacity has become the focus of everyone's consideration, especially in the field of metal cutting, which requires high metal processing efficiency and high surface quality, so general cutting tools do not have the above two Square effect, such as boring cutter, rolling cutter and so on, its structure is relatively simple, and work efficiency is relatively low

[0003] When the existing boring tools and scrapers scrape and grind the metal inner wall, the metal inner wall often has some roughness that affects the smoothness. Therefore, a hob is required for reprocessing to remove these roughness

This requires two steps to complete, time-consuming and labor-intensive

In addition, when the hob enters and exits the metal pipe, it sometimes rubs against the wall of the original size, causing wear marks on the wall, resulting in waste
