Abstract

A screw tap machining method is characterized in that coarse steel material is acidized and polished to remove surface dirt so as to obtain a blank, aging treatment is performed on the blank, thermal treatment is then performed on the blank, low-temperature preheating temperature is 245-300 DEG C, tempering temperature is 124-345 DEG C, tempering time is 30-40 minutes, machining a screw tap on a lathe, burr and quenching treatments are performed on a tapping part, quenching temperature is 500 DEG C, sand conditioning is performed on a screw tap part, carburization is then performed, the taken-out screw tap is soaked in mixed solution of polyurethane and sodium benzoate, the concentration of the polyurethane is 45-60%, and the concentration of the sodium benzoate is 4-5%. By the method which is simple and few in steps, the screw tap with the durable screw tap part can be manufactured, use of the screw tap is facilitated, and machining progress is increased.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing method of a screw tap. Background technique [0002] When the drill bit is used for a period of time, the threads will be worn and broken. In order to save materials and funds, a tap should be used to tap the drill bit. However, the tapping part of the tap is often worn out and scrapped. Contents of the invention [0003] The invention provides a processing method of a screw tap. The method can produce a higher-strength screw tap tapping part, prolong the life of the screw tap, and reduce material waste and purchase cost. [0004] A kind of processing method of screw tap [0005] Coarse materials are acidified and polished to remove the dirt on the steel surface of the coarse materials. Get blanks. [0006] Aging heat treatment is carried out on the blank. [0007] Then carry out heat treatment, the temperature of low-temperature preheating ...
