A rolling mill is a cold forming equipment that uses circular cutting tools to process involute spline, helical, and roller teeth. The machine tool applies the principle of gear meshing transmission, with the workpiece positioned by two end center holes. As the workpiece rotates, the two circular cutting tools roll into the workpiece to form the spline.
The blades are precision ground on high-precision grinding machines. The process of forming the workpiece is the transmission process of the gear pair. Compared to processes like hobbing, broaching, and skiving, rolling processing offers higher precision (reaching6-7High-grade precision, high processing efficiencyMaterial-saving, high gear tooth strength (due to cold rolling processing, the mechanical strength of the gear teeth is significantly higher than that of other cutting processes). Compared to gear grinding, it offers more flexible and convenient tool usage; lower tool manufacturing and management costs; and a wider range of adaptability for workpiece diameters.
Machine tools are suitable for straight and helical splines on various shaft parts such as automotive transmission gear shafts, ball joint constant-velocity joints, spline shafts, motor shafts, textile rollers, torsion springs, steering gears, crankshafts, and other shaft components.
Machine tools feature a horizontally arranged layout with an independently developed operating interface, significantly reducing the required skill level of the operators and lessening the labor intensity for workers.。
Positioning of cutting tools and workpieces can be selected manually or via an electronic handwheel, facilitating adjustments of the machine tool.。
The workpiece is installed between the front and rear tips, and can be optionally processed using either radial rolling or axial rolling methods, achieving high machining accuracy and a highly polished surface finish in just a few seconds.。
High productivity, capable of finishing multiple rolling teeth in one go (by shifting the workpiece to complete multiple rolling teeth), and flexible for processing various parts.。
Available for machining large keyway sections with small-width cutters. Significantly reduces the cost of tooling usage.。
Energy-saving and environmentally friendly, machine tools utilizeCNCControl and screw drive, stabilize processing accuracy, and save energy as well as minimize oil usage to the greatest extent.。
This machine tool is designed for cold rolling involute spline production based on the involute principle. Processing involute splines using this principle offers high efficiency, high strength of the machined tooth surfaces, and material savings. Therefore, this machine tool is particularly suitable for mass production in industries such as automobiles, motorcycles, and tractors. The machine has good rigidity and is easy to adjust. Once properly adjusted, it can perform radial and axial cyclic processing.
This machine tool features seven servo motion axes.:
● The main motion system composed of a tool spindle driven by left and right servo motors via respective reducers.
●Radial movement system achieved by the left and right servo motors of the machine tool, each driving the left and right sliding seats through their respective screws.
● A superior clamping and releasing motion generated by the front and rear servo motors, each driving their respective screws.
● The rotational movement of the workpiece.
