Detailed Description
The utility model is further described by the following detailed description in conjunction with the accompanying drawings.
Example 1:
as shown in fig. 1 to 5, a pipe threading tool includes a tool body 1. The tool body 1 is provided with a mounting hole. The mounting hole is located in the center of the tool body 1. The tool body 1 is rectangular. The cutter body 1 is provided with two thread cutting edges 2. Two thread cutting edges 2 are respectively arranged on two sides of the cutter body 1. The tool body 1 is made of a tungsten-cobalt alloy. Two sides of the cutter body 1 are respectively provided with a positioning groove 4.
As shown in fig. 4, the rake angle of the thread cutting edge 2 is α, and the relief angle of the thread cutting edge 2 is β. The angle alpha is 5 to 30 degrees and the angle beta is 5 to 10 degrees.
The mounting hole is a counter bore. The mounting hole is composed of a first hole body and a second hole body, a step surface is formed between the first hole body and the second hole body, and the diameter of the first hole body is larger than that of the second hole body. The inner wall of the second hole body is a conical surface, and the diameter of one end, close to the first hole body, of the second hole body is larger than that of the other end of the second hole body.
