A drilling and tapping integrated composite tap

Abstract

The integrated drilling and tapping tap of the present invention includes a shank and a blade, and the key point is that the blade is composed of a drill at its end and a tap near the shank. The front part of the present invention adopts the combination form of a drill bit and a tap. After drilling, the tapping thread can be realized without changing the tool, and the scattered processes are reasonably concentrated, the number of processes is shortened, the process is simplified, and the time for clamping and tool changing is saved. , reducing the number of special machine tools and special fixtures, shortening the production line, simplifying equipment design, and improving production efficiency; and the integrated structure of drilling and tapping also ensures the precision of its processing, thereby ensuring product quality. The drilling-tapping integrated tap of the present invention can effectively improve the working efficiency of processing internal threads by combining the drill bit and the tap, and can also reduce production costs while ensuring product quality.

Description

technical field [0001] The invention belongs to the technical field of cutter manufacturing, and in particular relates to a drilling and tapping integrated composite tap. Background technique [0002] The traditional internal thread processing method is to use a suitable drill to process the thread bottom hole first, and then use a tap to tap the thread. The disadvantages are: scattered processes, more machine tools and processes required, and frequent replacement of drills and taps , not only the productivity is low, but also the coaxiality of the drill bit and the tap is difficult to guarantee after the tool change, which affects the product quality and causes a lot of inconvenience in production. Contents of the invention [0003] The object of the present invention is to provide a drilling and tapping integrated tap, which can effectively improve the working efficiency of processing internal threads, and can reduce production costs while ensuring product quality.
