Description
Technical field:
The utility model relates to mechanical equipment technical field, is specifically related to a kind of veneer reeling machine.
Background technology:
Veneer reeling machine (being also furling plate round machine) is a kind of for carrying out the bending lathe of continuity point to metal blank.Two roller rolling machines, three rolls plate bending machine and four-roll plate bending machine can be divided into by its structure.The flitch that two roller rolling machine multi-processing sizes are less, four-roll plate bending machine is then generally used for machining large flitch, as ship plate etc.Upper roller of press brake acts on piston in two lower roll central symmetry positions by the hydraulic oil in hydraulic cylinder and makes vertical displacement movement, driving two lower roll gear engagements to rotate, providing moment of torsion for rolling sheet material by the final-stage gear of main gear reducer.Between three working rolls (two lower rolls, top rolls) of the smooth plastic metal plate of specification by veneer reeling machine, pressing down and the rotary motion of lower roll by top roll, make metallic plate through multi-pass continuous bend, produce permanent plastic deformation, roll into required cylinder, cone cylinder or their part.The field difference of veneer reeling machine owing to using, kind is also just different.From roller number point three rolls plate bending machine and four-roll plate bending machine.Three rollers divide again symmetrical expression three rolls plate bending machine, horizontal down-regulation type three rod veneer reeling machine, Curve down veneer reeling machine.The top roll of existing veneer reeling machine is merely able to lifting running, level can not operate, can not realize pre-bending function.
Utility model content:
The purpose of this utility model is to provide a kind of four-roll plate bending machine, and its structure is simple, easy to operate, can realize pre-bending function, pre-bending and volume circle is completed on same equipment, improves operating efficiency.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises frame, top roll, lower roll, side roller, hydraulic jack, hydraulic stem, rack rail, frame is connected with top roll by the output gear of reductor on it, frame both sides are provided with rack rail and hydraulic jack, hydraulic jack is connected with hydraulic stem, hydraulic stem is connected with lower roll, and the both sides of lower roll are provided with several sides roller, and side roller is connected with rack rail.
Operation principle of the present utility model: top roll is driven by reductor, provide moment of torsion for rolling sheet material, lower roll does vertical displacement movement by hydraulic jack, to clamp sheet material, two side rollers do banking motion along rack rail, can realize the pre-bending of sheet material end.
The utility model has following beneficial effect: its structure is simple, easy to operate, can realize pre-bending function, pre-bending and volume circle is completed on same equipment, improves operating efficiency.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Referring to Fig. 1, this detailed description of the invention is by the following technical solutions: it comprises frame 1, top roll 2, lower roll 3, side roller 4, hydraulic jack 5, hydraulic stem 6, rack rail 7, frame 1 is connected with top roll 2 by the output gear of reductor on it, frame 1 both sides are provided with rack rail 7 and hydraulic jack 5, hydraulic jack 5 is connected with hydraulic stem 6, hydraulic stem 6 is connected with lower roll 3, and the both sides of lower roll 3 are provided with several sides roller 4, and side roller 4 is connected with rack rail 7.
The operation principle of this detailed description of the invention: top roll 2 is driven by reductor, there is provided moment of torsion for rolling sheet material, lower roll 3 does vertical displacement movement by hydraulic jack 6, to clamp sheet material, two side rollers 4 do banking motion along rack rail 7, can realize the pre-bending of sheet material end.
This detailed description of the invention has following beneficial effect: its structure is simple, easy to operate, can realize pre-bending function, pre-bending and volume circle is completed on same equipment, improves operating efficiency.
