Tooth rolling machine is a multi-functional cold rolling forming machine, tooth rolling function in its rolling pressure range of the workpiece under the cold state of thread, straight lines, twill rolling;Rolling of straight teeth, helical teeth and helical spline gears;Straightening, reducing, rolling and all kinds of forming rolling.The machine has a safe and reliable electrical, hydraulic execution and control system, can make each working cycle manual, semi-automatic and automatic three ways to choose, the following macro platinum rolling mill small make up for you to introduce the advantages and characteristics of rolling mill.

The cold rolling process is an advanced non-cutting process, which can effectively improve the internal and surface quality of the workpiece. The radial compressive stress generated during the processing can significantly improve the fatigue strength and torsion strength of the workpiece. It is an ideal process with high efficiency, energy saving and low consumption.

Advantages of Macro platinum mechanical tooth rolling machine:

1. High efficiency and high precision

2. Durable construction

3. Extremely simple operation

4. Wide application

Two or three rollers in the tooth rolling machine are used to roll the screws, which are replaced by an effective cooling casting process to form a metal structure. The benefits of this process are not only faster and more accurate, but also greater elongation, shear force and durability than the rolling screws produced by the cutting method

Tooth rolling machine is mainly divided into: two axis eccentric type, two axis rolling through type, two axis hydraulic type, two axis hydraulic rolling through type, three axis CAM type, three axis hydraulic rolling through type multiple models.The rolling dies are respectively installed on the rotating shaft of the two-axis and three-axis machine when machining the thread. The extrusion thread is formed and the rolling dies of different specifications are replaced with different threads by rolling.It can process triangle thread, ladder pattern, straight pattern, net pattern, twill pattern, etc.

Features of the rolling products of Macroplatinum triaxial tooth rolling machine:

1. Tooth rolling is a plastic deformation, different from automatic lathe and other cutting processes, there is no scrap iron;

2. The surface of the thread after tooth rolling can improve the strength and hardness due to cold hardening;

3. Surface roughness is less than that of turning, milling and grinding;

4. The processed products are better in perpendicularity and concentricity than those processed by two-axis tooth rolling machine, and the precision is also higher;

5. High material utilization rate;The productivity increases more than that of cutting, and it is easy to realize automation.

6. The rolling tooth mold has a long life.However, the hardness of the workpiece material shall not exceed HRC40

7. High requirements on the size accuracy of the blank (only the blank itself of the vertical degree and precision can be good through the three-axis tooth rolling machine to produce high-precision products);

8. The precision and hardness of the rolling tooth mold are also high, so it is difficult to manufacture the mold

9. Not suitable for asymmetrical thread of rolling teeth.
