A kind of equipment for bending, forming and tempering automobile glass
Technical field
The utility model relates to the vehicle glass processing unit (plant), is specially adapted to the bending, forming and tempering automobile glass device.
Background technology
Traditional bending, forming and tempering automobile glass device comprises bending mechanism, transporting mechanism and air grid mechanism.As everyone knows, the process of vehicle glass moulding be in process furnace, be heated earlier, come out of the stove, brake forming, tempering and cooling.Equipment will be finished the vehicle glass bending, moulding and tempering process, at first pass through bending mechanism, the remollescent vehicle glass that is heated is arranged up and down at the bending mechanism of setting curvature under the roll-in of roller-way and formed curve form, be sent to air grid mechanism by transporting mechanism then, change vehicle glass internal stress characteristic, form glass tempering stress by air grid mechanism rapid quench, thereafter glass is cooled again, is sent to down the sheet platform.
Bending mechanism in the orthodox car glass bending moulding tempering equipment has two kinds, a kind of is the conventional hinge lever: with the hinge form various T templates are linked together, make the vertical plate of T template change the pivot angle degree with the leverage adjusting, the set face of T template transverse plate reaches sets any curvature.When being heated softening vehicle glass and flowing into bending mechanism, can form the identical curved surface of curvature that forms with a plurality of T template transverse plate end face line segment aggregates.The advantage of this mechanism is that handiness is higher, and shortcoming is that the roller-way of its hinge lever accent arc mechanism is to be contained on the hinge, and convenient in order to transfer arc (waiting arc) mechanism design, the spacing of hinge is equidistant, and distance is generally between 75mm~90mm.Because hinge and lever inevitably exist the gap, under action of gravity, just cause the inhomogeneous little change of the lonely curvature of face, when vehicle glass flows into, owing to be moulding in the bending mechanism of the inhomogeneous little change of cambered surface curvature, cause the vehicle glass cambered surface after the moulding to become disparity curvature, the vehicle glass optical property and the curvature consistency of moulding are all relatively poor, increase the duration of service with equipment, it influences increase, the spacing of the delivery roll of this mechanism can not design too for a short time simultaneously, and can only be equidistant, when causing vehicle glass to flow into since spacing form at the easy gravitate of formative stage greatly wavy, little to radius-of-curvature, difficulty is big, the demanding vehicle glass moulding of optics is very unfavorable.
Another kind is a conventional springs steel plate mechanism, as U.S. Pat 4,292, and the Steel Spring Plate mechanism of 065 Sheng Ge our company, the two ends hinge couples together with telescoping mechanism (hydraulic pressure or screw mandrel), regulates collapsing length and sets any curvature.The shortcoming of this mechanism is the camber that is difficult to guarantee a complete iso-curvature, because stress point concentrates on the two ends of Steel Spring Plate, the middle portion of steel plate bending and both sides part curvature are inhomogeneous, when vehicle glass flows into, because moulding in the uneven bending mechanism of cambered surface, cause the vehicle glass cambered surface curvature after the moulding also to be difficult to symmetry, influence vehicle glass optical property and shape face.
In sum, vehicle glass curvature inequality that traditional equipment for bending, forming and tempering is produced and optical property and curvature homogeneity are all undesirable, can not satisfy the more and more higher specification of quality of Hyundai Motor glass well.
The utility model content
The technical problems to be solved in the utility model is the defective that overcomes bending mechanism in traditional equipment for bending, forming and tempering automobile glass, promptly utilize hinge leverage and Steel Spring Plate to combine and transfer arc, overcome the curvature homogeneity of vehicle glass and the technical barrier of poor optical properties, a kind of equipment for bending, forming and tempering automobile glass is provided.
Scheme of the present utility model is: bending mechanism is by corresponding bending mechanism and roller are formed up and down, bending mechanism then is made up of both sides bending mechanism separately respectively up and down, and the bent mechanism of every lateral bending is made up of Steel Spring Plate, movable joint framework, riser, bearing support, Steel Spring Plate two ends and riser are movably hinged, Steel Spring Plate and movable joint framework are hinged, there is a fixed knot at middle part, movable joint framework base, and a plurality of bearing supports are installed on the Steel Spring Plate.
Advantage of the present utility model is: when the space framework that Steel Spring Plate and movable joint framework are formed is crooked, it is integrally bending, its section modulus is more much bigger than single Steel Spring Plate section modulus, though external force be 3 stressed, but external force is delivered to successively a plurality of spaced points of Steel Spring Plate by the rhombus parallel shelf of T template lower end by T template, movable joint hook isostatic, make Steel Spring Plate multiple spot producing balanced forces, combine with bigger section modulus, make the space framework integrally bending, curvature all with, error is minimum.Simultaneously because curvature is identical everywhere, be fixed on the Steel Spring Plate the bearing support spacing can requirement be provided with differently with tempering by moulding, but the pairing curvature of each bearing support is still identical.
Transfer the spacing of the hinge of arc mechanism to enlarge between the 100MM--150MM on the hinge lever in addition, under same long distance, employed hinge lever quantity obviously reduces like this, and existing number of gaps reduces, and progressive error reduces, weight saving.Then by the elastic force effect of cloth at regulations and parameters mechanism upper spring steel plate, just can adjust curvature all and cambered surface, thoroughly overcome preceding two kinds of mechanisms because of stress deformation homogeneity and the inhomogeneity shortcoming of gap affects mutually.

Embodiment
Structure of the present utility model comprises supporting mechanism, bending mechanism, transporting mechanism and air grid mechanism, bending mechanism comprises two corresponding up and down cover bending mechanism and rollers 2, bending mechanism then comprises both sides bending mechanism separately respectively up and down, and the bent mechanism of every lateral bending is by Steel Spring Plate 1, the movable joint framework, riser 3, bearing support 4 is formed, Steel Spring Plate 1 two ends and riser 3 are movably hinged, Steel Spring Plate 1 is hinged with the movable joint framework, there is a fixed knot at middle part, movable joint framework base, a plurality of bearing supports 4 are installed on the Steel Spring Plate 1, bending mechanism is inverted each other up and down, last lower roll becomes the recessed curvature of epirelief, and last lower roll keeps the corresponding spacing of sheet thickness.
The movable joint framework is by the hinged T template set of forming in one line of the transverse plate head and the tail of several same T templates 5, T template 5 in middle part of T template set is fixed on the frame 7 by a connecting rod 6 locatees as fixed knot, the transverse plate end face of each T template 5 is close to Steel Spring Plate 1, all fix a movable joint hook 8 on each T template 5, movable joint is linked up with on vertical plate that 8 bottom strips are fixed on T template 5, horizontal elongated slot is arranged at top, this groove agrees with on Steel Spring Plate 1, groove width is slightly slightly bigger than Steel Spring Plate 1 thickness, vertical plate bottom of T template 5 is a stationary shaft 9, the rhombus parallel bands of being made up of many groups movable joint rhombus 10 is installed in T template 5 bottoms, each rhombus apex of rhombus parallel bands is a circular hole, be linked in movingly on the stationary shaft 9 of vertical plate bottom of T template 5, and axial location.
The horizontal elongated slot of movable joint hook 8 is the plane on one side, is arc surface corresponding to the other side of Steel Spring Plate 1 curvature inboard.
Theory of machines of the present utility model just is Steel Spring Plate, the set of T template, rhombus parallel bands three are formed space framework, this space framework can recoverable deformation have the section modulus bigger than Steel Spring Plate again, because strutted an intersegmental distance by the set of T template between Steel Spring Plate and the rhombus parallel bands, so it is big that section modulus becomes, the elastomeric objects section modulus is big more, external force is big more when then crooked, section modulus is big more on the other hand, internal stress is big more when then being out of shape, internal stress distributes also balanced more, is out of shape also balanced more.We make full use of this internal stress makes the Steel Spring Plate multiple spot stressed.
When regulating curvature, Steel Spring Plate 1 two ends are by riser 3 jack-up, because fixed knot is by a T template 5 at middle part, the positioning action of movable joint hook 8, fixed knot produces reactive force, three external force make Steel Spring Plate 1 bending, because each movable joint hook 8 all agrees with on Steel Spring Plate 1, then make angle of each T template 5 corresponding all corresponding curvature circle-center swing, make stationary shaft 9 geometric positions of vertical plate end of T template 5 be a radian, distance widens, and that each movable joint rhombus 10 of rhombus parallel bands is all parallel-crank mechanism is scalable, then the rhombus parallel bands also is elongated and is line segment combination shape circular arc, can analyze rhombus parallel bands ortho states from the force analysis is the smooth plate combination, be line segment combination circular arc after the bending, this distortion makes the rhombus parallel bands produce overall inner-stress, elastic recoil power just, this returning place force all acts on every single rhombohedral apex, again by T template 5, movable joint hook 8, act on the Steel Spring Plate 1 that agrees with horizontal elongated slot, make Steel Spring Plate 1 every spacer producing balanced forces, therefore curvature all with, changed prior art Steel Spring Plate only 3 stressed inequalities and state, the creativeness of this physical construction that Here it is.
Principle in another Machine Design is: the bearing support 4 of this bending mechanism is mounted on the Steel Spring Plate 1 and since this structure curvature all with, so bearing support 4 can be equidistantly location and installation do not influence the curvature surface of roller 2.And the warp architecture of the pure T template of prior art, roller can only be installed on equidistant T template swivel pin, can't be applicable to unequal-interval.When the vehicle glass moulding, the roller-way spacing should be as far as possible little, as long as can satisfy the requirement of delivery roll intensity: finish to enter tempering during the stage when moulding, the roller-way spacing can suitably be amplified or progressively be strengthened, satisfying the requirement of hot air discharge, we can be according to the arrange by oneself spacing of bearing support 4 of specific requirement.
Before the start if up and down bending mechanism separately the bending mechanism of both sides adjust to same curvature, arrange roller 2 its two ends more and insert two side shaft holders 4, then softening vehicle glass just is pressed moulding through the space between two rollers, 2 rows up and down after the start.Then air-cooled, tempering, sheet down.
In addition, each air draft grid 11 of air grid mechanism are as long as be fixed on its two ends vertical plate inboard of T template 5 by stationary links 12, then single air grid row also can be along with T template 5 angles change and change simultaneously, and it is equidistantly vertical with crooked vehicle glass that air grid nozzle 13 directions are remained.
Riser 3 can be hydrostatic transmission, screw mandrel transmission, also can be the flexible structure of band transmission agency, as chain, wireline etc.
