Brief Description of Operation (Free Standing CGF1 Flange Rollformer)

The machine is designed to form the CGF 20/30 Profile on both edges (outboards) per pass at a rate of approximately 16 -17 meters per minute.

A heavy duty frame construction with 18/20 station multiple variable centered rollforming section, tooled for the returned and stitched flange profile outboard of the side plates spaced approximately 200 mm apart, on durable rollshafts. The lower rollshafts are carried within sealed-for-life deep groove ball bearing blocks, individually adjustable for roll centre and forming pressure, utilizing ‘disc spring’ stacks.

The hardened steel roller tooling carries intermediate rolls to allow forming down to 400 mm long without trolley and 200 mm with trolley. The last two stations of the rollforming section perform the stitching operation.

Bottom and top rollshafts are driven by hardened spur gear train via idler gears, carried by sealed-for-life deep groove ball bearings on the lower withdrawable idler shafts. These shafts connect the heavy side plates, thus creating the rigid head assembly and allow ease of individual removal for maintenance. The machine is driven at a speed of 16 -17 metres per minutes, by means of a geared electric motor and triple heavy-duty chain drive to the rolling head gear train.

With hardened adjustable in-feed guide bars fitted to the in-feed end of the rolling head, which is in turn carried by a totally guarded, robust, fabricated base frame, with fixing and leveling points. A jack adjustable exit-straightening roll is fitted to correct any vertical bow in the product.
