Vertical spline rolling machine is a kind of cold rolling forming equipment that uses rack die to gradually form involute splines, helical teeth and roller teeth. , The two progressive rack cutters plunge into the work while driving the workpiece to rotate, and the progressive rack plunges into the work to form a lower tooth shape, and the material extruded by the cutter die flows along the eating profile of the cutter die to form the upper teeth shape.
The cutter die is ground by a high-precision special grinder, which can achieve 3-level accuracy. The workpiece forming process is actually the transmission process of the rack and pinion pair of the two racks. The accuracy of the rack determines the accuracy of the workpiece, so the workpiece can be made To extremely high precision, compared with the processing technology of gear hobbing, gear shaping, gear shaving, etc., gear rolling processing has high processing precision (can reach 5-6 precision), high processing efficiency (processing rhythm 8-15s/piece), and material saving , High strength of workpiece teeth (because it is cold-rolled processing, the mechanical strength of teeth is much higher than that of other workpieces that are machined, and now OEMs are obliged to require supporting manufacturers to use cold forming technology to process products).
The vertical spline rolling machine is suitable for straight teeth ( Precise chip-free cold forming of helical) splines, threads, worms, straight threads, oil grooves.
Vertical gear rolling machine features:
(1) Wear-resistant castings made of special materials and frame preloaded rigid body.
(2) The unique synchronization gap fine-tuning technology improves the synchronization accuracy to the extreme.
(3) Rich mold combination methods, which can reverse the tooth rolling to save the mold.
(4) Intelligent guide rail lubrication detection function, workpiece forming trace aerosol cooling.
(5) Reasonable structure design, pleasant control feeling, saving floor space.
(6) In the direct drive mode of the synchronous rack, the life of the screw is greatly improved.
(7) Double servo motors are driven synchronously to realize low noise and precise forming process.
(8) Intelligent full-servo front and rear top technology can effectively solve the security identification of clamping.
