Description
Technical field:
The present invention relates to veneer reeling machine technical field, be specifically related to a kind of cylinders with small diameter flexible roll bending digital control two-roller veneer reeling machine.
Background technology:
It is a difficult problem of roll bending industry that cylinders with small diameter rolls always, and people rely on shaping finished product cylindrical shell to meet its instructions for use always.
Along with cylinders with small diameter is boilers and pressure vessel, shipbuilding, petrochemical industry, automobile, Aero-Space, the widely using of electromechanics and machine-building, as ventilation shaft, chimney, filter, automobile exhaust pipe, liquid storage (gas) tank etc., solve this difficult problem and seem particularly urgent.
Summary of the invention:
The object of this invention is to provide a kind of cylinders with small diameter flexible roll bending digital control two-roller veneer reeling machine, it mainly solves because less top roll can not carry the problem of power suffered by plate roll.And the technical process such as pre-bending, centering, volume circle, set round can be eliminated, easy to operate, plate end is approximate without straight flange, and one-shot forming, efficiency is high.
In order to solve the problem existing for background technology, the present invention adopts following technical scheme: it comprises frame 1, lower rubber roller 2, lower roll transmission device 3, Hydraulic Station 4, electrical control cubicles 5, lower roll lifting mechanism 6, top roll 7, it also comprises unloading mechanism 8, top roll supporting mechanism 9, lower rubber roller 2 is arranged in frame 1, lower roll transmission device 3 is connected with the rotating shaft of lower rubber roller 2, Hydraulic Station 4, electrical control cubicles 5 is arranged on the downside of frame 1 respectively, two lower roll lifting mechanisms 6 are connected with the two ends of lower rubber roller 2, top roll 7 is arranged on the upside of lower rubber roller 2, unloading mechanism 8 is arranged on the side of top roll 2, the upside of top roll 7 is provided with top roll supporting mechanism 9.
Described top roll supporting mechanism 9 supports gusset 9-2, friction block 9-3 by crossbeam 9-1, friction block, crossbeam 9-1 is provided with uniformly several friction block supporting gusset 9-2, and the lower end of friction block supporting gusset 9-2 is provided with friction block 9-3.
Described lower rubber roller 2 is the flexible roller of steel core outsourcing polyurethane elastomer material.
Operation principle of the present invention is: at the friction block 9-3 of top roll supporting mechanism 9, under the state of pressure beam top roll 7, starts power supply, starts PLC simultaneously, and hydraulic jack drives lower roll rise and contact with top roll, in top roll 7 part press-in lower roll elastomer; (begin end) is placed between top roll 7 and lower rubber roller 2 in sheet material one end, start lower rubber roller 2 to rotate (rotating forward), due to the effect of frictional force, sheet material feeds, plate enters between upper and lower roll, around and top roll 7 of fitting is pressed in elastomer, plate bends thereupon, and the radius of curvature that plate occurs bending and deformation is relevant to top roll mould diameter.Obtain the cylindrical shell of small diameter, top roll 7 is just relatively little, because less top roll 7 can not carry the power suffered by plate roll, therefore, being bearing on top roll 7 always, making it not produce deflection deformation from starting top roll supporting brake pad.
When sheet material begin near into termination or with brake pad support gusset contact time, lower roll stops operating (rotating forward), lower rubber roller 2 drop to continue to clamp plate with top roll 7 and lower rubber roller 2 rotates time plate to follow up the state that can not bend.Lower rubber roller 2 is rotated further (rotating forward), until the plate other end (terminal) is positioned at top roll 7, the vertical line position at lower rubber roller 2 center stops.
Then, lower rubber roller 2 rises to sheet material bending laminating top roll 7, starts lower rubber roller 2 main transmission and rotates backward, the half that roll bending is straight, until sheet material terminal contact last item brake pad supporting gusset stops, namely such sheet material be configured as cylinders with small diameter, start discharging device, exit cylindrical shell.
The present invention has following beneficial effect: solve because less top roll can not carry the problem of power suffered by plate roll, eliminate the technical process such as pre-bending, centering, volume circle, set round, easy to operate, and plate end is approximate without straight flange, and one-shot forming, efficiency is high.
