Information

The process route of flat thread rolling die is: blank forging → quenching and tempering → machining → inner hole quenching → machining (thread rolling) → outer diameter melting and tempering → inspection.

Low price flat thread rolling die from China manufacturer
The flat thread rolling die manufacturer tells you that the forging quality of the blank should be strictly controlled, and serious carbide segregation is not allowed in the thread part, otherwise it is easy to break the teeth during thread rolling. The purpose of quenching and tempering is to improve the forging structure and obtain lower hardness and plasticity so that the thread can be rolled after machining. Quenching and tempering is carried out in a box furnace, holding at 550~600°C for 2 hours, then rising to 890±10°C and holding for 4~6 hours, then air cooling or oil cooling, tempering temperature 760±30°C, holding temperature for 6~ After 8 hours, the furnace is cooled to 600~650°C, then water-cooled to 300°C, and then cooled to room temperature in air. Hardness after quenching and tempering HB2017-241.
The quenched and tempered blank is then machined and formed, and the inner hole is treated with high frequency, and then the thread is rolled. The rolling die manufactured by the rolling method has a higher service life than that manufactured by the turning method. Inner hole high-frequency melting fire, single-turn or double-turn inner hole inductors can be used. The manufacturer of flat thread rolling die tells you that the carbides of this kind of high alloy steel are not easy to dissolve, so it is not suitable to use too high heating speed.
