Product Description

Thread Rolling Machine Mould

Thread rolling is an integral cold-forming process, used to produce a variety of threads, knurls and helical gears. The process involves deforming a metal blank by rolling it through a die. This process forms external threads along the surface of the metal blank. Internal threads can be formed using the same principle. In contrast to other widely applied threading operations such as thread cutting, thread rolling is not a subtractive process. That means it doesn't remove metal from the stock. Rolled threaded fasteners offer advantages such as stronger threads, precise final dimensions, good surface finish, and a lower coefficient of friction.

In-feed rolling uses a timed machine cycle. This is used for the general rolling of parts up to the maximum width of the face of the dies, less die chamfers. In-feed rolling dies, also known as plunge rolling, are suitable for threading with a shoulder or a headed workpiece.

Thru-feed rolling is used for rolling threads that exceed the maximum face width of the dies, as well as for continuous rolling of long threaded bars. Here, the rolling dies have grooves with no pitch; the groove cross-section is that of the standard flank profile. The thread pitch is produced by skewing the die axes by the pitch angle of the thread. This means the workpiece is given an axial thrust and moves one pitch length in the axial direction for every full revolution.

The advantages of thread rolling dies including:1.Surface roughness is less than that of turning, milling, and grinding.
2.The surface of the thread after rolling can improve strength and hardness due to cold work hardening.
3.High material utilization rate.
4.Productivity is significantly higher compared to cutting, and it is easy to achieve automation.
5.The lifespan of rolling molds is very long.
