Abstract
The utility model discloses a vacuum bag for producing curved face sandwich glass. The vacuum bag comprises a silica gel bag body, wherein the silica bag body is provided with a vacuum suction mouth; and the edge part of the silica gel bag body is provided with upper and lower corresponding concave-convex rubber buckling ring groups. The utility model has the beneficial effects that: a vacuum bag for an interlayer which is safe without any potential quality hazard, can be recycled without causing any waste and can be rapidly assembled and disassembled for increasing the production efficiency is provided.
Description
Technical field
The utility model relates to glass deep processing field, mainly is a kind of vacuum bag of producing curved surface laminated glass.
Background technology
Laminated glass is widely used in fields such as curtain wall, partition, decoration as a kind of safety precaution glass, has become a kind of very common conventional products.But be confined to the interlayer aspect of sheet glass substantially, and the different bend glass interlayer of the bigger toughened glass interlayer of curvature, hot bending be owing to can not adopt conventional dull and stereotyped roll-in pattern preheating, and remain, can't accomplish mass scale operation in difficulty.
In order to solve this difficult problem, people develop the way of vacuum bag curved surface laminated glass are carried out processing.As be disclosed in No. 101417865 patents of invention of 2009-04-29, announced a kind of technology that adopts hot melt edge sealing technology and produce abnormal curved surface laminated glass, by utilizing disposable hot melt vacuum bag packaged glass goods, cold-draw, heat are taken out successively again, cooling, still press, thus the required curved surface laminated glass of system.But this method causes wastes and pollution easily owing to adopt disposable plastics bag, adopts space adhesive to connect between suction nozzle and the bag, and former material waste is inevitable, and production cost increases; And need to assemble vacuum slot in force, cause manpower waste and quality worry;
Be disclosed in No. 2823256 patents of 2006-10-04, set forth a kind of technology that adopts the vacuum bag production curved surface laminated glass of reusable edible.Because the air suction nozzle is arranged on bag itself, avoided the loaded down with trivial details of each dismounting and quality worry, spread all over and adopt many latch closure knot sealed structures, convenient disassembly has improved production efficiency greatly, has also reduced manufacturing cost.But this mode causes the gas leakage of limit portion easily, and especially the nook tends to the phenomenon that clasp comes off occur under the condition of thermal expansion, causes hidden danger of quality easily.
The utility model content
The purpose of this utility model will overcome the deficiency of above-mentioned technology just, and a kind of vacuum bag of producing curved surface laminated glass is provided.
The utility model solves the technical scheme that its technical problem adopts: the vacuum bag of this production curved surface laminated glass, comprise the silica gel bag, the silica gel bag is provided with vacuum slot, and the edge section of described silica gel bag is provided with corresponding concavo-convex rubber clasp group up and down.
As preferably, the surface of described concavo-convex rubber clasp group is coated with calcium sodium based lubricating oil fat.
As preferably, the rounded chamfering in whole corner of described silica gel bag.
The effect that the utility model is useful is: provide the no hidden danger of quality of a kind of safety, reusable edible not to have the interlayer vacuum that waste, energy fast assembling-disassembling are enhanced productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Description of reference numerals: silica gel bag 1, concavo-convex rubber clasp group 2, vacuum slot 3, bend glass 4.
Embodiment
The utility model is described in further detail below in conjunction with embodiment:
As shown in Figure 1, the vacuum bag of this production curved surface laminated glass, comprise silica gel bag 1, silica gel bag 1 is provided with vacuum slot 3, the rounded chamfering in whole corner of described silica gel bag 1, the edge section of described silica gel bag 1 is provided with corresponding concavo-convex rubber clasp group 2 up and down, and the surface of described concavo-convex rubber clasp group 2 is coated with calcium sodium based lubricating oil fat.
The about 1mm of described silica gel bag thickness can effectively stick on the surface of glass article when vacuumizing, increase cold-draw suction; The silica gel material is the high temperature resistant silica gel of sulfuration, and working temperature is more than 150 ℃.
Wherein concavo-convex rubber clasp group implementation strict corresponding interlock up and down, it is poor to adjust whole perimeter according to its thickness difference, so that avoids extending inequality after the thermal expansion, drawing back the hidden danger that gas leakage is caused in the slit.
Wherein, calcium-sodium soap grease plays sealed against leakage gas, about 120 ℃ of dropping points, and when envrionment temperature during near 100 ℃, usefulness is progressively lost, and is convenient to follow-up dismounting.
The technical process of described bend glass 4 comprises: 1, glasswork is placed in the silica gel bag.2, calcium-sodium soap grease is smeared on rubber clasp surface.3, buckle clasp, the sealed vacuum bag.4, be not more than under the pressure condition of 0.1Mpa, utilizing the set vacuum slot of bag self to carry out cold-draw.5, keep the state vacuumize, envrionment temperature is risen to 100 ℃ according to the requirement that per hour is not higher than 40 ℃, and constant temperature and pressure 1～2 hour.6, keep vacuum state, be cooled to envrionment temperature.7, stop to vacuumize, work piece are taken out in unpacking.8, autoclave gone in work piece, carry out still and press.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
1. a vacuum bag of producing curved surface laminated glass comprises silica gel bag (1), and silica gel bag (1) is provided with vacuum slot (3), it is characterized in that: the edge section of described silica gel bag (1) is provided with corresponding concavo-convex rubber clasp group (2) up and down.
2. the vacuum bag of production curved surface laminated glass according to claim 1 is characterized in that: the surface of described concavo-convex rubber clasp group (2) is coated with calcium sodium based lubricating oil fat.
