Abstract
The invention discloses a method for manufacturing horizontal roller-free hyperboloid toughened glass, and belongs to the technical field of glass forming and toughening. The process flow is that the plate glass is placed on a hyperboloid forming mould in the middle of an L-shaped trolley, and is lifted to a pushing area B from a loading and unloading area A through a lifting mechanism, and after the L-shaped trolley carries the glass to move horizontally and enters a heating hot bending area C, the lifting mechanism resets; in the area C, glass is formed in a hot bending mode, the heat-insulating partition plate is opened, the L-shaped trolley penetrates through the upper turnover area D and enters the air cooling area E, and the heat-insulating partition plate is reset; the formed glass between the upper and lower combined air grids in the E area is air-cooled and toughened; the L-shaped trolley exits from the zone E to the zone D and descends to a lower turnover zone F through a receiving and descending mechanism, then passes through a channel G arranged below the zone C and returns to the zone A for unloading and loading glass, and meanwhile, the receiving and descending mechanism resets and enters the next cycle. The invention has reasonable process flow, good optical performance of the toughened glass, high yield, energy saving, less equipment investment and suitability for continuous batch production.
Description
Technical field
The present invention relates to a kind of glass ware forming tempering technology field, especially relate to the making method that a kind of level does not have the roller-way double curved toughened glass.
Background technology
The making method of existing double curved toughened glass roughly has two classes: the one, hang the tempering method, and glass is being provided with the production line operation of channel-type heating chamber and pressing and forming air grid by special hanger along track.Its main drawback is owing to heating chamber can not better seal cause the serious wave of the energy useless, and impression is hung, the therefore incompatible making glass that specification of quality is higher, breadth is bigger or heavier by the both side surface place, upper edge of glass.Second kind is the horizontal roller formula double curved glass method of at present domestic and international widespread usage, its main making method is that sheet glass is sent on the ceramic roller in the heating zone by outer roller-way, glass leaves the heating zone after back and forth moving thermally equivalent on the ceramic roller and reaching softening temperature, enter the shaping area of forming by roller-way equally, again by picking up or isolated plant such as picking-up, make the certain height that rises on glass, glass is dropped into moulding on the mould that moves under it, the mould holder glass of forming enters and is provided with then, air-cooled section that makes up air grid is down carried out air-cooled tempering.Main drawback is the accuracy requirement strictness to mould and associated mechanisms, equipment making cost height, and ceramic roller costs an arm and a leg also fragile, the insulation expense height of roller-way maintenance and heating zone, in entire making process, because glass back and forth operation on ceramic roller, glass surface very easily produces damage, and influencing the optical property of toughened glass, yield rate is not high.
Summary of the invention
The purpose of this invention is to provide a kind of production process rationally, reliable, energy utilization is abundant, good forming effect, the optical property of toughened glass can be guaranteed effectively, the yield rate height, production cost can reduce significantly, and a kind of level that adapts to the continuous batch production requirement do not have the making method of roller-way double curved toughened glass, to solve the existing problem of prior art.
The technical scheme that realizes the object of the invention is: a, at first will need the sheet glass of brake forming and tempering to be placed on vertical surface to be provided with on the mould of " L " shape dolly that thermal insulation layer, horizontal plane are framework and the middle part hyperboloid forming mould that is provided with the frame formula; B, the lifting mechanism that is provided with raceway by both sides are promoted to " L " shape dolly the corresponding position of the propelling district B on its top by the loading place A of bottom, " L " shape dolly is entered the heating hot bending district C that both sides are provided with raceway from advancing district B translation, and lifting mechanism decline simultaneously resets to loading place A and waits for; C, sheet glass at heating hot bending district C by behind progressively heating and the hot bending, open the thermal-insulation baffle plate that is located between heating hot bending district C and the turnover district D, " L " shape dolly pass turnover district D enter and air grid corresponding with the curved surface of formed glass be in open mode by upper and lower combination air grid and pipeline, blower fan constitutes and both sides are provided with the air-cooled district E of raceway, thermal-insulation baffle plate resets; D, upper and lower combination air grid close up to the corresponding position blowing hot bending glass are carried out air-cooled tempering; After e, air-cooled tempering finished, upper and lower combination air grid was opened, and " L " shape dolly is retracted into turnover district D, and dropped to turnover district F by the descending mechanism that connects that is provided with the both sides raceway equally; F, " L " shape dolly pass channel region G along the both sides raceway level of heating C bottom, hot bending district and reenter loading place A, unload, glaze; Simultaneously, the descending mechanism that connects of reducing to down turnover district F rises to turnover district D wait, enters next circulation.
The invention has the advantages that: the present invention adopts " L " shape dolly, and on the frame formula hyperboloid mould of " L " the shape dolly that will need the glass of moulding to be placed on, the peripheral camber line of the double curved toughened glass of its making is accurate, good in optical property, yield rate height; The vertical surface of " L " shape dolly is provided with thermal insulation layer in addition, when " L " shape dolly is in heating hot bending district, its vertical surface forms good sealing with the region of interest in heating hot bending district, adds that thermal-insulation baffle plate has cut off the heat loss of heating chamber effectively, so the save energy effect is obvious; Adopt the circular flow of upper and lower layer simultaneously, so the manufacture craft flow process is reasonable, floor space is few, and the required equipment configuration is simple, and technology maturation is reliable, adapts to the requirement that continuous batch is produced.
