Abstract
A technology for producing the strengthened glass bowl (or dish) with wrinkle vein includes such steps as providing a special mould, preparing the raw glass plate with wrinkle vein, loading it in preheated mould, high-temp shaping, strengthening, and post-treating of surface.
Description
Technical field:
The present invention relates to glass bowl manufacturing technology field, particularly a kind of have the toughened glass bowl of fold lines, a production technique of basin.
Background technology:
At present, glasswork is used more and more widely, for example all is widely used at aspects such as glass bathroom facility, dinner glass articles for use, glass ornaments.But with the technology that present glass industry is produced, can only produce thickness toughened glass bowl basin uniformly, perhaps be non-toughened glass bowl basin.At present, toughened glass bowl basin in process of production, in order to ensure tempering smoothly, the thickness of its product is must thickness even, to avoid fracture phenomena occurring in the tempering process.Its production technique mainly comprises following step:
At first, former of sheet glass is cut;
Then, the glass of well cutting is placed on the mould mouth of bowl basin moulding;
Then, the mould that is placed with sheet glass is placed in the baking oven heats, make that sheet glass is softening to fit in mould inner surface,, be shaped to a bowl basin according to the moulding of mould;
At last, the glass bowl with moulding carries out the tempering processing.
Be made generally in the circular arc of surface smoothing according to the toughened glass bowl basin of above-mentioned technology manufacturing.But the shape of this product, moulding are too simple, and same other materials (as pottery, metal) product is compared and lacked uniqueness, and competitiveness of product is lower.If be also to be difficult to the moulding of fluctuating curved surface reach according to present technology but directly toughened glass bowl basin is designed to the surface.And if make non-toughened glass bowl basin, though can form above-mentioned state the bowl basin, it certainly will be difficult to satisfy safety requirements such as its intensity, heatproof difference.
Summary of the invention:
The objective of the invention is to overcome the above-mentioned deficiency of product, the toughened glass bowl that a kind of production has the fold lines, the production technique of basin are provided.
The present invention is for realizing its purpose, and the technical scheme that production technique adopted is: at first, former of a desired shape sheet glass is ready to, this former is single flat sheet glass or bilayer or multiwalled sheet glass body; Secondly former of ready sheet glass is lain on the described particular manufacturing craft, this mould is formed with accordion, up-and-down convex-concave surface; The particular manufacturing craft that then will place former is with 700～900 ℃ heat, make former softening, be attached to the convex-concave surface of mould, then glass object is taken out, lowering the temperature naturally is shaped to work in-process.Then these work in-process are positioned in the bowl forming mould of preheating, and enter baking oven once more and carry out the high temperature hot bending, temperature is between 700～800 ℃; High temperature bowl basin after the last moulding carries out tempering to be handled; And with the bowl basin behind the tempering) carry out operation such as surperficial aftertreatment.
The toughened glass bowl basin that adopts production technique provided by the invention to produce, its basin body has equally surface of concavo-convex fluctuating lines, similar silk fold by at first forming on the particular manufacturing craft.Carry out forming processes at the sheet glass that will be formed with the fold lines then, obtain a bowl basin moulding.Handle by special tempering at last and obtain final toughened glass bowl basin.By the product that the present invention makes, not only peculiarly shaped, attractive in appearance, and through the tempering processing, performances such as product strength, heatproof difference reach safety requirements, and product has the good market competitiveness.
Description of drawings:
Fig. 1 is the vertical view of particular manufacturing craft of the present invention;
Fig. 2～5th, the schema of production technique of the present invention;
Fig. 6 is the user mode figure of finished product bowl basin of the present invention.
Embodiment:
As shown in Figure 1, particular manufacturing craft 1 of the present invention has the accordion of being formed with, up-and-down convex-concave surface 11.
See Fig. 2～5, production technique of the present invention is:
1, prepares original sheet glass.
Former 2 of the sheet glass of needs processing being prepared in advance, decide according to the shape of bowl basin mouth usually, so be generally circle, is that flow velocity, flow are even when making next step glass melting mobile like this; According to the design needs, also have square, oval, Polygons etc.This former 2 is single flat sheet glass or bilayer or multiwalled sheet glass body.
2, molten stream
Former 2 of the sheet glass of well cutting is lain against on the described particular manufacturing craft 1, with 700～900 ℃ heat, make former 2 of sheet glass softening, be attached on the convex-concave surface 11 of particular manufacturing craft 1, then glass object is taken out, cooling is shaped to work in-process 201 naturally.
3, hot bending
After an amount of remollescent glass subsides are attached to the convex-concave surface 11 of mould for former 2, it is taken out from stove together with mould 1, naturally cooling is 1～3 minute, when making the glass of work in-process 201 lower the temperature hardening naturally, and is reduced to before 550～720 ℃ in temperature, take off from described particular manufacturing craft 1, and put into the forming mould 3 of preheating fast, and to put into the high temperature baking oven and heat once more, temperature is between 700～800 ℃, make the glass of work in-process 201 be subjected to thermal softening, finish hot bending.These forming mould 3 preheating temperatures are at 100～500 ℃, and forming mould 3 is through after the preheating, and the situation of breaking can not appear having in the parison that takes off from particular manufacturing craft 1 when placed thereon.
4, tempering is handled
After finishing bowl basin 202 behind the hot bending and forming mould 3 and from baking oven, taking out, in normal temperature, left standstill 15～75 seconds, when being cooled between 650～750 ℃, glass is taken out, put into the annealing furnace tempering, the tempering wind speed is kept 15～45m/s, continues tempering 30～60 minutes, is cooled to normal temperature to bowl basin 202 and gets final product.
5, aftertreatment such as surface
In sum, the toughened glass bowl basin 203 that adopts production technique provided by the invention to produce, its basin body is by at first forming concavo-convex fluctuating shape, the same textured surface of similar silk fold on the particular manufacturing craft 1.Carry out forming processes at the sheet glass that will be formed with the fold lines then, obtain a bowl basin moulding.Handle by special tempering at last and obtain final toughened glass bowl basin.By the product that the present invention makes, not only peculiarly shaped, attractive in appearance, and through the tempering processing, performances such as product strength, heatproof difference reach safety requirements, and product has the good market competitiveness.
The present invention has broken through the limit of sheet glass hot bending, has greatly expanded the purposes of glasswork, can better remedy the opaque defect of ceramic analogous products.
