Problems solved by technology
Thread processing is completed on a CNC lathe. Due to the use of non-free cutting tools on the market, it is difficult to solve the problem of uneven load distribution between the teeth, which may cause low service life of the product, and easily Caused by cutting the knife, it not only causes damage to the tool, but also greatly reduces the service life of the tool, thereby reducing production efficiency, and may damage the workpiece and cause the product to be scrapped. Therefore, the tools currently used in the market cannot meet the development needs of the oil pipeline processing industry.

The invention discloses a thread machining tool. The thread machining tool comprises a tool body. The tool body is provided with an operating face on the side. The center of the tool body is provided with a mounting hole. A cutting tooth group of roughing teeth and finishing teeth is arranged on the operating face. The thread machining tool is characterized in that the tooth crest of each finishing tooth is in an arc-linear form and matches with a thread in tooth form, the tooth crest of each roughing tooth is in an arc-linear form smaller than the tooth form of the thread, the roughing teeth and the finishing teeth have a 0.1+ / -0.025mm crest difference, edging angle of the tool body is 3 degrees, edge radian R of both the finishing teeth and the roughing teeth is 0.8mm, and edge height of the finishing teeth and the roughing teeth is 3+ / -0.15mm. The thread machining tool using a free cutting mode is small in cutting force, the teeth on the tool bear evenly distributed load, the tool is high in capabilities of chip removal and chip breaking, the service life of the tool is prolonged, and production efficiency is improved.
Description
technical field [0001] The invention relates to the field of processing tools, in particular to a thread processing tool. Background technique [0002] In recent years, with the development of the oil pipe processing industry, the requirements for the service life of thread cutters and their surface quality are getting higher and higher. Thread processing is completed on a CNC lathe. Due to the use of non-free cutting tools on the market, it is difficult to solve the problem of uneven load distribution between the teeth, which may cause low service life of the product, and easily Knife punching not only causes damage to the tool, but also greatly reduces the service life of the tool, thereby reducing production efficiency, and may damage the workpiece and cause the product to be scrapped. Therefore, the tools currently used in the market cannot meet the development needs of the oil pipeline processing industry. Contents of the invention [0003] In order to solve the abov...
