Along with development of technology and development, at present a lot of producers generally adopt following production process when production has the cylindrical edge glass bowl: 1, make hot melt cylindrical edge mould; 2, plate glass hot melt cylindrical edge; 3, bowl Pengcheng type is handled; 4, tempering is handled; 5, the limit grinding of bowl basin, polishing, painted postprocessing working procedures.The production technology and the particular manufacturing craft thereof of a kind of glass bowl, basin are disclosed as: Chinese patent application numbers 200510035041, publication number 1699228, its production stage is: 1, make particular manufacturing craft, 2, hot melt post limit, it is semi-finished product that plate glass is positioned over the particular manufacturing craft hot melt molding; Concrete mode is for to lie in former of ready plate glass on the described particular manufacturing craft, and this particular manufacturing craft is formed with a concave surface, and this concave bottom forms groove; The particular manufacturing craft of the placing plate glass high temperature with 600～800 ℃ is heated, make plate glass softening, be attached to the concave surface of particular manufacturing craft, continuing heating makes the plate glass temperature maintenance between 800～1000 ℃, make plate glass begin fusing, the glass that order begins to melt flows into groove along the taper concave surface of particular manufacturing craft, takes out the nature cooling then and is shaped to semi-finished product, and this semi-finished product bottom forms flange according to groove.3, a bowl basin hot bending is handled: these semi-finished product 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 ℃; 4, tempering is handled: the high temperature bowl basin after the moulding is carried out tempering handle; 5, at last the bowl basin behind the tempering being carried out surperficial postprocessing working procedures gets final product.Its tempering processing is that the bowl basin semi-finished product behind hot bending are put into common tempering machine, and it is conventional physical toughened to implement to act on high temperature bowl basin with the constant normal temperature wind of a kind of wind speed.Its weak point is: if treat that the bowl basin of tempering is the glass bowl of a uneven thickness etc., then carrying out conventionally when physical toughened, will certainly cause tempering inhomogeneous, and make the heat resistance of product poor, impact resistance power is poor.
Summary of the invention:
The objective of the invention is to have the production technology of cylindrical edge glass bowl in the deficiency of carrying out causing when tempering is handled the tempering inequality at existing, and provide production technology with cylindrical edge glass bowl, its tempering is effective, greatly reduce the tempering cost, promoted the security performance when product uses.
The production technology with cylindrical edge glass bowl among the present invention includes following steps: a, employing hot melt cylindrical edge mould, prefabricated plate glass is placed on puts into high temperature baking oven hot melt above the mould together, after glass surface after dissolving trickles once more and forms cylindrical base when level and smooth, hot melt cylindrical edge mould and glass are taken out from baking oven together, in normal temperature, allow glass lower the temperature naturally, b, it is taken out the bowl Pengcheng pattern tool of putting into preheating then from the hot melt mould; C, once more put into baking oven hot bending, moulding, come out of the stove; D, the cylindrical edge glass bowl after coming out of the stove take out from mould to be put into the tempering machine and carries out physical toughened processing; E, use special basin limit grinder to carry out edging then, polishing, colouring postprocessing working procedures; When physical toughened processing, by adjusting the size of tempering machine air outlet, allow the thin position of glass accept bigger wind-force, less wind-force is accepted at the edge that glass is thicker.
Wind-force during described control tempering is 4/5～2/3 of traditional tempering.
Outstanding effect of the present invention is: (1), improve the tempering apparatus of plate glass hot bending bowl basin targetedly, the cylindrical edge glass bowl is realized easily physical toughened, the loss control that makes its tempering process reduces the tempering cost greatly in 1%; (2), because surging on the tempering link, realize the tempering of product fully, the temperature difference resistance of product, impact resistance power are strengthened greatly, even if product breaks, also be fine granularity, reduce injury greatly, thereby promoted the safe in utilization of product greatly the user; (3), through the grinding in later stage and the product of polishing, not only can not change the transparency of glass, can increase the transparency of bowl basin on the contrary, perfection highlights intrinsic glittering and translucent of glass; (4), because to the complete tempering of bowl basin and the reservation fully of the glittering and translucent essence of glass, various post-processed and painted coming true are carried out in its surface, it is abundant greatly that product is obtained, to satisfy the demand of various personalizations.
