The invention discloses a thread sleeve formed through cold heading and a forming method, relates to the technical field of threaded sleeves formed through cold heading, and aims to solve the problem of high cost caused by the defects of low production efficiency, low material utilization rate and the like due to the fact that a special-shaped curved surface connecting base is realized by adopting machining and the like in the prior art. A welding matching curved surface is arranged at one end of a thread sleeve body, a positioning surface is arranged at the other end of the thread sleeve body, a locking screw groove is formed in the interior of the positioning surface, a tool withdrawal groove is formed below the locking screw groove, a cylindrical through hole is formed in the bottom of the tool withdrawal groove, and the cylindrical through hole extends to the surface of the welding matching curved surface in a penetrating mode. Blank forming except for internal threads of a curved surface connecting base is achieved through a six-station high-speed forming machine, and after a blank is formed, machining of the internal threads of the curved surface connecting base, the thread tool withdrawal groove and the cylindrical through hole is completed through a numerical control lathe.
Description
technical field [0001] The invention relates to the technical field of cold heading forming screw sleeves, in particular to a cold heading forming screw sleeve and a forming method. Background technique [0002] In the automobile piping system or other fluid piping systems, in order to monitor the temperature, oxygen content, pressure, etc. The fixed screw sleeve is fixed on the curved surface of the metal fluid pipeline, so that various sensor monitoring devices such as real-time temperature, oxygen content, and pressure of the pipeline fluid can be installed to ensure the safe operation of the metal fluid pipeline. [0003] However, in the prior art, the connection base of this special-shaped curved surface is realized by machining, etc., but its production efficiency is low, the material utilization rate is not high, and the cost is high; therefore, it does not meet the existing needs. We propose a cold heading forming screw insert and forming method. Contents of the i...
