Product Description
The thread rolling machine is a multi-functional cold extrusion forming machine tool. The thread rolling machine can perform thread, straight and twill rolling on the workpiece in a cold state within the rolling force range; spur gears, helical gears and helical spline gears Rolling; straightening, reducing, rolling and various forming rolling. The machine has a safe and reliable electro-hydraulic execution and control system, which allows each working cycle to be selected from three modes: manual, semi-automatic and automatic.
Thread rolling cold rolling process is an advanced non-cutting process that can effectively improve the intrinsic and surface quality of the workpiece. The radial compressive stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece. It is a kind of An ideal process with high efficiency, energy saving and low consumption.
The principle of cold rolling processing of small module 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 driven by the transmission mechanism. The R wheel can be driven by the oil cylinder to perform 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 positioned and clamped with two central holes. The clamp can be adjusted to move the workpiece axially. When it is stressed, it can swing at an angle Φ around the axis parallel to the machine tool spindle through point O on the clamp to ensure that the workpiece is always in the cold rolling process. It keeps the two rolling wheels in a free rolling state and facilitates clamping of the workpiece.
The rolling wheels must be adjusted synchronously, that is, the indentations of the L and R wheels on the workpiece surface must be adjusted to coincide. If the synchronous adjustment is inaccurate, the workpiece will have irregular teeth, chips, and out-of-tolerance. The center height of the workpiece is consistent with the center height of the rolling wheel (allowed to be 0.01-0.08mm lower). The commonly used adjustment methods are:
After the rolling wheel is worn out, the teeth can be ground off to reduce the number of teeth, and the parameters can be recalculated according to the above process, and the teeth can be re-opened to produce a refurbished rolling wheel. It can be refurbished multiple times within the allowable range of the machine center distance.
