Spiral roller machine

Abstract

Rolling the linear strip of single and laminated (multilayer) plates to produce a spiral shell, constituting part or whole wall of a cylinder and tubular element, is a procedure performed by using the forms and moulds. The stringers (beams) of round or curved stairs and their handrails are examples of spiral shells and elements constituting part of cylinder wall. Pipes with spiral joints are the example of spiral shell constituting whole wall of a cylinder and tubular element. This patent provides the design of a spiral roller machine and its relevant calculations to adjust the machine, and the procedure to roll spiral shells and elements according to the required shape.

1 . A machine which rolls the linear strip of single and laminated plates to produce stringer, handrail, pipe with spiral joints, and any spiral shell and profile on which the axe of bent is not perpendicular to the longitudinal line of work-piece, constituting part or whole wall of a cylinder, comprising rollersets which each rollerset consist of at least two rollers on a common straight axe passing through the centre of rollers pivot and these axes of rollersets always remain parallel and make an angle φ with the perpendicular line to the plates of roller machine, as defined in “Description” and/or “Drawings”. 
   
   
       2 . The rollerset which comprises two parallel roller mounting parts, top and bottom pin connection, rollers having two pins connecting one pin to each roller mounting part, and their required connections, which acts like a louver, as defined in “Description” and/or “Drawings”. 
   
   
       3 . In machine of  claim 1 , the rollerset of  claim 2 . 
   
   
       4 . In machine of  claim 1 , variant 1 of rollersets comprising one roller mounting part, pin connection, and roller balls connecting to the roller mounting part, and their required connections, as defined in “Description” and/or “Drawings”. 
   
   
       5 . In machine of  claim 1 , variant 2 of rollersets comprising one roller mounting part, pin connection, and rollers connecting by one pin to the roller mounting part, and their required connections, as defined in “Description” and/or “Drawings”. 
   
   
       6 . In machine of  claim 1 , the rollerset comprising the rollers connecting to the drawers of top and bottom plates, and the top plate can move in the alignment of the support of top plate by moving its tightening bolts in the provided grove of support element, in order to adjust the vertical distance between top and bottom parallel plates according to the width of work-piece designate to roll, as defined in “Description” and/or “Drawings”. 
   
   
       7 . In machine of  claim 1 , the jack or adjusting wheel system which adjusts the transversal angle of top and bottom plates with horizon in order to ease the output alignment of work-piece, as defined in “Description” and/or “Drawings”. 
   
   
       8 . In machine of  claim 1 , the gearbox and angle indicator connecting to top or bottom plate and the support of top plate which shifts the top plate to adjust and indicate the angle of rollersets with top and bottom plates, as defined in “Description” and/or “Drawings”. 
   
   
       9 . In machine of  claim 1 , the sliding drawers system and their scroll and shift indicator connecting to the top and bottom plates which shift the rollersets and indicates the amount of the shift, as defined in “Description” and/or “Drawings”. 
   
   
       10 . In machine of  claim 1 , the automated operating system in which programmed hardware adjusts, operates, and controls all the mentioned rolling procedure, as defined in “Description”. 
   
   
       11 . In machine of  claim 1 , the hydraulic system comprising liquid reservoir, pump, rotor, pedals, valves, jack and connections which provides the motion of moving devices, as defined in “Description” and/or “Drawings”. 
   
   
       12 . In machine of  claim 1 , the feeding roller connecting to the rotor, which drives the work-piece back and forth, as defined in “Description” and/or “Drawings”. 
   
   
       13 . In machine of  claim 1 , the electric feeder which drives work-piece and can be used as another variant of hydraulic feeding system, as defined in “Description”. 
   
   
       14 . In machine of  claim 1 , the supports of top plate and their tightening screws which release or restrict the rotation of rollersets and consequently the proportional shift of plates, as defined in “Description” and/or “Drawings”. 
   
   
       15 . In machine of  claim 1 , the body which supports the plates and main part of machine. 
   
   
       16 . In machine of  claim 1 , the welding and joining machine to weld or join the spiral joints in spiral shell constituting the whole wall of cylinder as defined in “Description”. 
   
   
       17 . In machine of  claim 1 , the clamp applied to tighten the layers of laminated work-piece as defined in “Description” and/or “Drawings”. 
   
   
       18 . in machine of  claim 1 , any combination of members, variants, and options of  claims 2  to  17 .
