What is the working principle of the thread rolling machine?

The  thread rolling machine is a multi-functional cold extrusion forming machine tool. The  thread rolling machine can process the thread, straight grain and diagonal grain rolling on the workpiece in a cold state within the rolling force range. So what is the working principle of the thread rolling machine?

What is the working principle of the  thread rolling machine
The thread rolling machine is a multifunctional cold extrusion forming machine tool. The thread rolling machine can process the workpiece in a cold state within the rolling pressure range, such as thread, straight grain, and oblique grain rolling; straight teeth, helical teeth, and helical spline gears rolling; straightening, reducing, rolling and various forming rolling. The machine has a safe and reliable electric-hydraulic execution and control system, which allows each working cycle to be selected from three modes: manual, semi-automatic and automatic.
The thread rolling cold rolling process is an advanced non-cutting process, which can effectively improve the internal and surface quality of the workpiece, and the radial compressive stress generated during processing can significantly improve
It is an ideal process with high efficiency, energy saving and low consumption to improve the fatigue strength and torsional strength of the workpiece.
The principle of cold rolling processing of small modulus involute splines on a  thread rolling machine. L and R are a pair of involute rolling wheels with the same parameters, which are respectively installed on the two main shafts of the thread rolling machine
and can rotate synchronously in the same direction under the drive of the transmission mechanism. The R wheel can be driven by the oil cylinder for radial feed movement, and the L wheel can be adjusted to coincide with the indentation of the R wheel on the surface of the workpiece F through the adjustment of the adjustment mechanism. The workpiece P is positioned and clamped by the two center holes. Adjusting the fixture can make the workpiece move axially. When the force is applied, it can swing a middle angle around the axis parallel to the spindle of the machine tool at the upper point of the fixture, so as to ensure that the workpiece is always maintained during the cold rolling process. It is in a free rolling state with the two rolling wheels, and at the same time it is convenient for clamping the workpiece.
The structural size, geometric tolerance and technical requirements of the rolling wheel are formulated with reference to the thread rolling wheel and the cylindrical measuring gear. The common normal length or cross-rod distance M of the rolling wheel is calculated according to the spline data in the gear industry. The required material can be Cr12MoV .
