The Working Principle And Use Of The Thread Rolling Machine

Concept: A multifunctional cold extrusion forming machine.

Classification: two-axis thread rolling machine and three-axis thread rolling machine.

The main function of the thread-rolling machine is to stop the thread, straight line and twill rolling of the workpiece under the cold state, and then stop rolling on the straight tooth, the helical tooth and the oblique spline gear, and then one can Stop rolling on straightening, reduction, rolling, and various forming parts. Its operation mainly relies on safe and reliable power. Its main system has liquid execution system and control system. There are three working cycle forms, manual, semi-automatic and automatic.

There are two main types of thread rolling machine market, one is the two-axis thread rolling machine, which is more common because of the cheap price. The other is a three-axis, three-axis machine that mainly processes thin-walled tubular engineering parts, such as the hollow screw of an engineering building.

The cold rolling process of the thread rolling machine is currently a more advanced non-cutting process, which can better improve the internal and external quality of the workpiece, and the radial compressive stress generated by the processing time can significantly improve the fatigue of the workpiece. Strength and strength of change, in general, is an efficient, energy-saving, low-cost, non-cutting process. The thread rolling machine manufacturer today introduces the working principle and application field of the thread rolling machine, and hopes to help everyone.

working principle:

The principle of cold rolling the small modulus involute splines on a thread rolling machine. L, R are a pair of involute rolling wheels with the same parameters, respectively installed on the two main shafts of the thread rolling machine, and can rotate synchronously in the same direction under the driving of the transmission mechanism. The R wheel can be driven by the cylinder for radial feed motion, and the L wheel can be adjusted by the adjustment mechanism to coincide with the indentation of the R wheel on the surface of the workpiece P. The workpiece P is clamped by two central holes, and the adjustment clamp can move the workpiece axially. When the force is applied, the workpiece can be swung by a Φ angle around the axis parallel to the machine tool spindle at the O point to ensure the workpiece is always in the cold rolling process. Keep the two rolling wheels in a free-to-roll state and at the same time facilitate the clamping of the workpiece.

The structural dimensions, shape tolerances and technical requirements of the rolling wheel are formulated with reference to the rolling wheel and the cylindrical measuring gear. The common normal length or span distance M of the rolling wheel is calculated according to the spline data of the gear, and the required material can be selected by Cr12MoV. (Hardness 59~62HRC).

Application areas:

Nowadays, the thread rolling machine is widely used in many fields such as construction industry, industrial processing, pipe processing, auto parts, etc. It can be widely used because it has many superior features, and the use of the thread rolling machine can just give People bring some convenience. The thread rolling cold rolling process of the thread rolling machine is an advanced non-cutting process, which can effectively improve the internal and surface quality of the workpiece, and the radial pressure generated during processing, which can significantly improve the fatigue strength and torsional strength of the workpiece. Knowing that the rolling cold rolling process is an ideal process with high efficiency, energy saving and low consumption. It is precisely because the thread rolling machine can achieve this process very well, so the application of the thread rolling machine is naturally more and more extensive.
