Embodiment
For shape of the present invention, structure and characteristics can be understood better, below will lift preferred embodiment and combine accompanying drawing to be elaborated.
Fig. 1 is that hyperbolic glass ware forming tempering device becomes arcuation attitude front schematic view; As shown in Figure 1; Hyperbolic glass ware forming tempering device of the present invention comprises a plurality of placed in-line roller-ways 1 down and is positioned at a plurality of placed in-line roller-way 2 of going up of roller-way 1 top down that respectively roller-way is crisscross arranged up and down.Air grid 4 is arranged in the middle of two last roller-ways 2 on each, is cascaded with last roller-way 2; Air grid 3 is arranged in the middle of two following roller-ways 1 under each, connects with following roller-way 1.Being positioned at intermediary roller-way and frame is fixed together.
Fig. 2 is a hyperbolic glass ware forming tempering device side schematic view, and last roller-way 2 is provided with convex surface, and correspondence is provided with concave surface on the following roller-way 1, goes up roller-way for every and is driven and moved up and down by the cylinder 7 at two ends, and the pressure of roller-way to pressing is provided.Since up and down roller-way to the pressure effect, be positioned at the glass between roller-way up and down can produce along roller shaft to bending, form curved surface with the male and fomale(M&F) same curvature.
Become the arc lifting mechanism and be positioned at frame top, connect the roller-way that is positioned at two ends through conduction chain 11.Become the arc lifting mechanism and can be winding plant, the roller-way that will be positioned at two ends through conduction chain 11 during work upwards promotes, and drives roller-way and becomes arc with air grid and become state shown in Figure 1.In that up and down the glass between the roller-way 10 can be crooked together along with roller-way, produce perpendicular to roller shaft to curved surface.Be provided with transmission rig up and down between the roller-way, can drive roller-way rotation up and down, make glass in to-and-fro movement between the roller-way up and down by external force.
Said roller-way with male and fomale(M&F) formation that can be formed in one also can be as shown in Figure 3, and the running roller that is not waited by diameter is enclosed within on the axle to be formed.The wide 6mm-10mm of running roller, diameter 35mm-60mm, spacing 50mm-90mm.Running roller between the adjacent roller-way is staggered, i.e. space between the running roller on all corresponding adjacent roller-way of each running roller on the roller-way is to avoid at formation impression on glass.Running roller can adopt polytetrafluoroethylmaterial material, also can restrict with outer embedding heat-stable material of metal wheel such as aramid fiber.Be employed on the axle mode of sheathed running roller and make the male and fomale(M&F) roller-way, can simplified processing process, reduce cost.
Said roller-way can also be as shown in Figure 4, and correspondence is made male and female face more than two sections or two sections on roller-way up and down, makes the present invention to process two or two simultaneously with upper glass along the roller-way direction, enhances productivity.
Fig. 5 is the technological process schematic diagram of hyperbolic glass ware forming toughening method of the present invention.During work, glass is accomplished the location in last fragment earlier, is transported to heating zone by parallel roller-way then.Glass is delivered to up and down between the roller-way of moulding tempering device of the present invention by roller-way after heating zone is heated to glass softening point, get into moulding tempering section.
This moment, roller-way and the air grid with male and fomale(M&F) of the present invention all was in the flattening position.After glass was accomplished into grid, the conduction chain traction that becomes the arc lifting mechanism was positioned at the roller-way at two ends, and the control lift stroke is to realize that roller-way becomes the curved surface that arc becomes predetermined curvature together with air grid.Roller-way back and forth rolls under external force up and down, makes thermoplastic glass in arcual to-and-fro movement between the roller-way up and down.Cylinder control is simultaneously gone up roller-way and is moved downward, and is producing squeezing action between roller-way up and down, makes glass ware forming go out and the identical curved surface of male and fomale(M&F) radian of roller-way up and down.After for some time, the air grid that is uniformly distributed between the roller-way blows out high wind, with the glass cools tempering, accomplishes the moulding tempering of glass.
Moulding tempering device flattens then, and last roller-way and last air grid lift, and glass is delivered to cooling section by roller-way, after blowing is cooled to down the sheet temperature, is sent to down fragment and unloads sheet.
The above description of this invention is illustrative, and nonrestrictive, and those skilled in the art is understood, and within spirit that claim limits and scope, can carry out many modifications, variation or equivalence to it, but they will fall in protection scope of the present invention all.
