DEVICE FOR FABRICATION OF ITEMS OUT OF METAL PLATES Russian patent published in 2015 - IPC B21C37/08 

FIELD: metallurgy.

SUBSTANCE: device contains frame, two flanges with windows and cylindrical holes to install driven and non-driven horizontal shafts with rollers, cushions, roll bearings and non-driven vertical assemblies of rollers and device for rollers changing. In the frame from the drive side of the horizontal shafts a longitudinal groove is made to secure one flange, the second flange is secured in the longitudinal grooves of the provided at least two carrying beams having possibility of movement at right angle to the longitudinal grooves using the device for rollers changing in the sliding guides made in the frame. The roll bearings of the horizontal shafts located in the second flange are installed on the spacing bushings with internal cone holes interacting with the made cone ends of the horizontal shafts and are secured by means of wedges. The device for rollers changing is made in form of the driven shaft located on the frame with bearing supports and rack-and-pinion gears, which gear wheels are installed on the driven shaft, and racks are installed in the bearing beams.

EFFECT: rigidity increasing of the device and quality improvement of items.
