Stock Vertical Cold Forming Spline Gear Rolling Machine

Spline cold forming is actually a chip-free process in which the root material is gradually extruded and replaced to the crown of the tooth.

Forming principles of rolling machine

Two opposed pairs of toothed rubbing dies installed on the sliding table move in a relative straight line after synchronization of synchronous gears by oil pressure and servo motor. The die is ground into a gradually penetrating toothed shape. The work piece is supported by the front and rear apex, and the processing position of the work piece can be conveniently adjust-ed by the displacement function of the front and rear apex. The relative movement of the die drives the work piece to select and gradually extrude the work piece, which is finally put out after shaping. The forming accuracy and stability of splines are obtained from the prefabricated rigid distance of the toothed mold, which completes the chip-free forming in seconds.

Process advantages of cold rubbing(Compared with traditional cutting)

Efficiency increase more than 30 times (about 10-20 seconds/piece);

40% increase in workpiece load-carrying capacity;

Roughness below Ra0.4;

Material savings 9%-15%;

Greater improvement in fatigue strength, torsional strength and wear resistance of toothed profile.
