Detailed description of the invention
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1~Fig. 6, a kind of method that uses veneer reeling machine Rolling Manufacture of Conical Cylinder, the two ends of described veneer reeling machine are respectively overturning frame 1 and fixed frame 3, in described overturning frame 1 inner side, volume cone frock 2 are installed.
Above-mentioned volume cone frock 2, comprises support 26, is provided with two cover friction stopping means on described support 26, and the structure of the described friction stopping means of two covers arranges axisymmetricly, and symmetry axis is by the plumb line of upper roller of press brake 5 cross-section center; Every cover friction stopping means comprises the bearing 25 affixed with described support 26, bearing pin 23, hinging supporting shaft 22 and roll sleeve 21; The top of described hinging supporting shaft 22 is back shaft, and arm 221 is pulled for location in bottom, and middle part is installing hole; On described bearing 25, be provided with relative two connecting holes and two relative the first gear holes, it is affixed by being inserted into pin and described bearing 25 in described the first gear hole that arm 221 is pulled in described location, described hinging supporting shaft 22 is rotatably connected on described bearing pin 23 by described connecting hole, the two ends of described bearing pin 23 are separately fixed in two described connecting holes, described roll sleeve 21 is fixed on described back shaft, in the time that workpiece rolls on veneer reeling machine, the periphery of described roll sleeve 21 is close on by the small end end face 27 of Rolling Manufacture of Conical Cylinder.
In the present embodiment, in order to be suitable for rolling of different size cone cylinder, on described bearing 25, be provided with the second gear hole 24, for adjusting the position of hinging supporting shaft 22, and then realize the position adjustment of roll sleeve 21.In order to extend the service life of roll sleeve, be provided with wearing layer at the periphery of described roll sleeve 21.
The operation principle of above-mentioned volume cone frock 2:
The blanking of cone cylinder is a fan-shaped steel plate, and Rolling Manufacture of Conical Cylinder on the veneer reeling machine with cylindrical work roll, ensure in the process rolling, the bus of workpiece overlaps with the bus of top roll.Fan-shaped steel plate the motion between working roll can regard as on workpiece bus each with the axial vertical direction of working roll on uniform motion and workpiece around the resultant motion of the gyration of certain any the plumb line by himself bus.On veneer reeling machine, major part is walked and hurry up or make microcephaly walk a little slower, can realize the motion that above-mentioned cone cylinder rolls.Therefore, on veneer reeling machine, Rolling Manufacture of Conical Cylinder applies a moment need to workpiece in addition, overcome the frictional force between workpiece and working roll, this is the principle of veneer reeling machine Rolling Manufacture of Conical Cylinder, and workpiece is around the required moment minimum of gyration of the plumb line of the point by self bus, therefore, applied moment preferably acts on the bus of workpiece, so the present invention acts on moment of friction by the small end end face of Rolling Manufacture of Conical Cylinder.
The present invention is by two roll sleeves that are arranged symmetrically with of small end end face arranged outside of Rolling Manufacture of Conical Cylinder, rely on frictional force and the position-limiting action of two roll sleeves and small end end face, realize fan-shaped steel plate around by the gyration of certain any plumb line on self bus, and make small end movement slows down, to realize cone cylinder rolling smoothly on veneer reeling machine.Detailed process is: roll sleeve applies opposing torque to workpiece, roll sleeve plays axial limiting to workpiece simultaneously, this axial limiting effect rolls guide effect exactly, under the effect of two roll sleeves, workpiece deflects, when workpiece is in the time that center line turns round, its small end end face, under the effect of two roll sleeves, remains in a plane vertical with its center line.
Stay under Action of Gravity Field in order to prevent from rolling roll bending in process, the present invention installs roll bending hydraulic lifting apparatus 4 on described fixed frame 3, and described roll bending hydraulic lifting apparatus 4 comprises column framework 41, sliding machine 45 and drive unit thereof, support bar 44 and roller 43, the both sides of described column framework 41 are respectively provided with a vertical guide 410, described sliding machine 45 is arranged between two described vertical guide 410, the setting vertical with described column framework 41 of described support bar 44, described support bar 44 adopts cantilever design to be fixed on described sliding machine 45, the described roller 43 of setting in parallel is installed on described support bar 44, the drive unit of sliding machine comprises the oil cylinder 49 of vertical setting, described oil cylinder 49 is arranged on described column framework 41, be provided with the perpendicular sprocket shaft being rotationally connected 47 at the external part of described oil cylinder 49, two ends at described sprocket shaft 47 are symmetrically installed with two sprocket wheels 48, on each described sprocket wheel 48, being equipped with one engages with it and affixed driving-chain 42, described driving-chain 42 is affixed with described sliding machine 45, described column framework 41 is provided with pull-back cable 46, and the upper end of described pull-back cable 46 is connected with the top of described column framework 41, and the lower end of described pull-back cable 46 is fixed on the fixed frame 3 of veneer reeling machine, described pull-back cable 46 and described support bar 44 split the both sides at described column framework 41, described support bar 44 be positioned at upper roller of press brake 5 directly over, described support bar 44 is parallel with upper roller of press brake 5, when the workpiece starting the arc is during to preset angles, the one end of slinging workpiece with crane, is placed in workpiece on described roller 43.
In the present embodiment, described vertical guide 410 is formed by channel-section steel.
Above-mentioned volume cone frock 2 also can be arranged on described fixed frame 3 inner sides, and compared with being arranged on described overturning frame 1 inner side, the roller 43 on roll bending hydraulic lifting apparatus 4 needs to lengthen, less stable.From rolling the overall structure of equipment, volume cone frock 2 is arranged on to described overturning frame 1 inner side, can make the overall structure of the equipment that rolls more stable.
The operation principle of above-mentioned roll bending hydraulic lifting apparatus 4:
In the time that veneer reeling machine carries out charging and rolls, roll bending raises along with the starting the arc, in the time reaching setting height, for preventing that roll bending from staying under Action of Gravity Field, can, with sling one of roll bending of crane, be placed on the roller of above-mentioned hydraulic lifting apparatus, makes roller choose roll bending.By controlling the input pressure of oil cylinder, control roller along with the moulding situation of workpiece moves up and down, can make the moulding roundness tolerance of workpiece less; While rolling, workpiece, by roller supporting, can reduce friction, makes to roll work convenient.
Although by reference to the accompanying drawings the preferred embodiments of the present invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing from the scope situation that aim of the present invention and claim protect, can also make a lot of forms, within these all belong to protection scope of the present invention.
