Description

Technical Field

[0001] The utility model relates to the technical field of internal thread cutters, in particular to a discarded internal thread cutter for efficient processing. Background Art

[0002] Internal thread processing is a very common hole-making requirement in parts and components of various industries. The internal thread processing process is usually: first drill the thread bottom hole and chamfer the hole mouth, and then use a tap to process the thread. The tap is a type of internal thread processing tool among thread tools. Its application characteristics are mainly used for thread processing of large, medium and small holes. According to different thread standard requirements, it is divided into metric thread, American thread and British thread. The existing internal thread processing is prone to the phenomenon that the tap breaks in the hole during the cutting process, making it difficult to repair the parts or causing the parts to be scrapped. Utility Model Content

[0003] The utility model aims to provide a high-efficiency disposable internal thread tool, which can solve the problem that the tap is prone to breakage in the hole during the cutting process, making the parts difficult to repair or causing the parts to be scrapped.

[0004] To achieve the above-mentioned purpose, a discardable internal thread tool for efficient processing is provided, comprising a steel base, a Pozidriv assembly surface is provided on one side of the steel base, a threaded cutter head is provided on one side of the Pozidriv assembly surface, a tapered-mouth bolt is provided inside the threaded cutter head, a tapered section is provided on one side of the threaded cutter head, a plurality of chip grooves are provided on the surfaces of the threaded cutter head, the tapered section and the steel base, a channel is provided inside the steel base, and a lateral water outlet is provided on one side of the steel base.

[0005] According to the high-efficiency disposable internal thread tool, the thread cutter head, the Pozidriv assembly surface, and the steel base are connected by tapered bolts.

[0006] According to the disposable internal thread tool for efficient processing, the lateral water outlet is connected to the channel.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. This is a high-efficiency discarded internal thread tool. The cutting edge material is solid carbide. The main purpose of the discarded design is to combine the advantages of carbide and steel. With the characteristics of the Pozidriv assembly interface, it can effectively protect the part hole from damage when the tool breaks during the cutting process. The broken tool position will form a separation at the Pozidriv assembly surface, thereby protecting the product part hole. The flexible steel structure ensures the stability of the tool and increases the economy.

[0009] 2. This is a discarded internal thread tool with high efficiency. By setting a tapered section, the outer diameter of the tapered section is not less than the outer diameter of the thread cutter head. The tapered section is used to drill a blind hole. There is a gap between the thread cutter head and the blind hole, which solves the problem of difficulty in removing the tool when it breaks.

[0010] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
