Abstract
The utility model relates to an upper pressure roller centralizer which is arranged on one end of an upper pressure roller. The upper pressure roller comprises a spacing mechanism, a first swing arm and a second swing arm, wherein the upper pressure roller is fixed on the spacing mechanism; the spacing mechanism is arranged on a rotating shaft which is hinged with two upper grid mounting plates; and one ends of the first swing arm and the second swing arm are respectively hinged on the two upper grid mounting plates, and the other ends are arranged on the spacing mechanism through axis pins. The spacing mechanism enables the upper pressure roller to be always on the central line of the distance between two adjacent delivery rollers in the bending and cambering process, thereby facilitating the bending formation of glass.
Description
Technical field
The utility model relates to a kind of upper pressure roller centering means.
Background technology
At present, in the crooked toughening process of glass production, arranged by some conveying rollers that support has high temp glass to be processed on the lower roller road that forms, the lower roller road can become arc along the bending of roller-way direct of travel according to the needs of production technique, high temp glass relies on himself also thereupon brake forming of gravity, discloses this method and apparatus in the patent No. is the Chinese patent of CN87106435.As shown in Figure 1, horizontal above the lower roller road for the upper air grid 3 of glass cools air-supply, arranged by some conveying rollers 1 and form in the lower roller road, and conveying roller 1 relative vertical position is adjustable, in order to make the lower roller road form the arc of setting.Along with the improvement of technology, the quality for the brake forming that improves glass is provided with pressure roller 4 on surface on glass, and upper pressure roller 4 is on two between the air grid 3, and is fixed on air grid 3 sidepieces.
When lower roller road horizontal positioned, upper pressure roller 4 is corresponding one by one with the position of below conveying roller 1, and upper pressure roller 4 is centered at two adjacent upper air grids 3.Along with the flexural deformation of roller-way, because upper pressure roller 4 is constant with its fixing air grid 3 distances, above pressure roller 4 departs from the middle position, this so that the formed precision of glass be affected.The middle position that how can make pressure roller 4 be positioned at all the time two air grids 3 in the roller-way BENDING PROCESS becomes the present stage problem demanding prompt solution.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of upper pressure roller centering means, and this device makes upper pressure roller in bending change arc process pressure roller is centered between two adjacent conveying rollers by stop means.
To achieve these goals, pressure roller centering means on the utility model, this device is arranged on an end of pressure roller, comprise position-limit mechanism, the first swing arm and the second swing arm, described upper pressure roller is fixed on the described position-limit mechanism, position-limit mechanism is arranged in the rotating shaft of hinged two upper air grid mounting plates, one end of described the first swing arm and the second swing arm is hinged on respectively on described two upper air grid mounting plates, the other end is arranged on the position-limit mechanism by bearing pin, and this position-limit mechanism becomes on the center line that makes all the time pressure roller be positioned at two adjacent conveying roll gaps in the arc process in bending.
Further, be provided with the fixed orifices and the microscler spacing hole that are positioned on the described center line on the described position-limit mechanism, position-limit mechanism is fixed on the described mounting plate by described fixed orifices and spacing hole, fixed orifices is nested with in the rotating shaft of hinged described two mounting plates, described the first swing arm and the second swing arm are plugged in this spacing hole by described bearing pin at its end away from mounting plate, when two mounting plates rotated relatively, it is mobile in spacing hole that the first swing arm and the second swing arm drive its bearing pin that is hinged on the position-limit mechanism.
Further, be provided with cylinder on the described position-limit mechanism, be provided with the axle bed of fixing described upper pressure roller on the piston rod of this cylinder, upper pressure roller leans upper pressure roller on surface on glass by stretching out of described cylinder piston rod.
Further, the other end of described upper pressure roller is provided with described upper pressure roller centering means equally.
Position-limit mechanism in the utility model realizes that by fixed orifices and spacing hole fix at 2, and these two holes are arranged on the center line that is positioned at two conveying roll gaps simultaneously, make the upper pressure roller that is fixed on the position-limit mechanism in crooked chain bends to the process of arc, remain setting placed in the middle, more be convenient to the glass bending moulding.
Description of drawings
Fig. 1 is the upper synoptic diagram of pressure roller when the roller-way brake forming in the prior art;
Fig. 2 is the structural representation of pressure roller centering means on the utility model;
Fig. 3 is the sectional view of A-A among Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figures 2 and 3, be upper pressure roller centering means of the present utility model, this device can be arranged on an end of pressure roller 4 as required, also can install the two ends at upper pressure roller 4.Upper pressure roller centering means comprises position-limit mechanism 7, the first swing arm 5 and the second swing arm 9, position-limit mechanism 7 is specially the platy structure of an inversion " L " type, horizontal section at " L " type position-limit mechanism is fixed with cylinder 8, be provided with the axle bed 12 of fixing upper pressure roller 4 ends on the piston rod 11 of cylinder 8, upper pressure roller 4 leans upper pressure roller 4 on surface on glass by stretching out of cylinder piston rod 11; Vertical section at " L " type position-limit mechanism is provided with fixed orifices and microscler spacing hole 13, position-limit mechanism 7 is nested with in the rotating shaft 10 of air grid mounting plate 2 on hinged two by fixed orifices, and by spacing hole 13, the first swing arm 5 and 2 interlocks of two mounting plates of the second swing arm 9 and this, one end of the first swing arm 5 and the second swing arm 9 is hinged on respectively on two upper air grid mounting plates 2, and the other end is plugged in the spacing hole 13 by bearing pin 6.Two mounting plates 1 are relatively during rotation, and the first swing arm 5 and the second swing arm 9 drive it and be hinged on bearing pin 6 on the position-limit mechanism 7 in spacing hole 13 interior movements.Simultaneously, fixed orifices and spacing hole 13 are positioned on the center line of two conveying roller 1 spacings corresponding with two mounting plates 2, and no matter how bearing pin 6 moves in spacing hole 13 remains on this center line, and then makes pressure roller 4 be centered at two conveying rollers 1.
Above-mentioned example just is used for explanation the utility model, and embodiment of the present utility model is not limited to these examples, and the various embodiments that meet the utility model thought that those skilled in the art make are all within protection domain of the present utility model.
