The new thread rolling machine equipped with a single starter unit are available from #1015 to #20 size to run fasteners for any kind of industry. The threaders can thread roll self-tapping screw, automotive parts, heat-treated parts and special profiles. The most important features of the machines are the starter unit driven by a Direct Drive motor and the bed frame which is made of pearlitic spheroidal cast iron including the contrast block making the machine the precise thread roller. The new drive unit is powered by a high-precision planetary gearbox with clutch brake which is unique for this machine size. This new type of drive with epicyclical reduction gear provides a cascade reduction ratio of the gear and favors higher torque and precision to run hardened parts. The feeding rails and the vibratory feeder have the motorization of the height positioning to facilitate the adjustment according the length of the parts. The machine comes with a vibratory feeder as standard feeding system included in the sound proof enclosure.
The most innovative feature is the brand new starter unit. The control of the introduction system is obtained by a torque motor. The motion of the introducing slide is realized by means of a linear movement on a guide. The introducer stroke can be adjusted by the operator panel or by means of the electronic handwheel avoiding any manual adjustment with service wrenches, ensuring speed and accuracy of measure change. The quality is manage by mean of a rejection gate to reject parts when the load monitor detect deviations allowing the production of perfect parts.
The modular system permits to install the machine with washer assembly units R1 or R2 and to integrate a station to feed head less parts automatically with a control of the orientation of the blank by video camera and a station to flip the parts in case of wrong orientation before the introduction into the starter unit.
