Description
[technical field]
The utility model is about a kind of sheet glass manufacture field, particularly about a kind of device of bending glass sheet.
[background technology]
Traditional shaping glass sheets method be with glass sheet support on curved frames or mould, the gravity by sheet glass self carries out bending, thereby forms the net shape of sheet glass.The moulding of this kind gravity has the border structure approaching with the final curved shape of sheet glass with bending mould.Sheet glass is placed in substantially horizontal mode on the periphery of frame of bending mould, the sheet glass of Zhi Chenging generally divides several formative stages according to differing temps by a bending furnace by this way.First stage is generally the preheating zone, be heated to temperature at the preheating zone sheet glass near the sheet glass softening temperature, the next stage is a shaping area, sheet glass is heated to 560 ℃-650 ℃ temperature there, the bending gradually owing to action of gravity then, sheet glass is complementary to reach desired curvature in the shape of periphery place and framework, and the last stage is the annealing cooling zone, sheet glass is annealed cooling, thereby just they can be removed from forming mould when leaving bending furnace.
The above-mentioned glass bending forming mould that is used for generally comprises a pedestal and a shaping frame, this shaping frame can be the framework of an overall fixed on this pedestal, also can comprise a pair of decide moulding limit and a pair of moving moulding limit, decide the moulding limit and be fixed on the pedestal long limit as this shaping frame, moving moulding limit by hinge with should to decide the moulding limit hinged, as the minor face of this shaping frame, and should moving moulding limit fix a balance flank that has a weight.The middle part is by decide the moulding edge forming when brake forming for big sheet glass, and the two ends sheet glass is after softening, and under the cooperation of weight, flank drives moving moulding limit and makes progress the continuous brake forming of sheet glass gradually around pin joint.
The mould of said structure can cause following problem in the sheet glass process of producing big radian, big sphere: 1. mold-mart is obvious: for the bigger sheet glass of sinuousness, big many of the size of its development size after than bending, therefore when sheet glass last slice, the contact position of glass and mould is just far apart from glass plate edge, like this when sheet glass softens moulding, sheet glass is just very long by the distance that the contact position slides into the edge, thereby cause the large-area slip vestige of sheet glass, influence the visual appearance of sheet glass; 2. the goodness of fit is uncontrollable: for the bigger sheet glass of side camber, length direction arch height ratio, easily produce flounce at the side of sheet glass, this has influenced the entrucking performance of sheet glass; 3. the sheet glass that the side sphere is big can't moulding: when the side sphere is very big, in the crooked initial stage, this part need be protruded greatly, when sheet glass is placed on the mould, the convex part sheet glass does not support because of having, sheet glass is softening when bending, and meeting is under the action of gravity of self, and is sagging to the opposite direction of normal curvature direction; 4. the reverse sphere in bight: long limit or side edge shape for the bight change rapid glass, and the bight is easy to generate reverse sphere; 5. optical property is not good: because the influence of factors such as glass sheet shape, mould anchorage force, glass sheet temperatures difference, the glass spherical transition that the center sphere is bigger has some setbacks, and optical property is not good.
In order to address the above problem, Chinese patent has disclosed a kind of dual flank forming mould for No. 00266195.0, this mould is formed dual flank by outer moulding ring and moving moulding ring, during shaping glass sheets, elder generation is according to the radian moulding of outer moulding ring, after outer moulding ring breaks away from, sheet glass and moving moulding loop contacts, radian moulding according to moving moulding ring, thereby formed twice moulding of sheet glass, prevented that to a certain extent dead load forming makes the sheet glass deflection cause flounce too greatly because of one time, also solved, also for the good effect of improving being arranged because of side edge shape changes the reverse sphere that sharply produces because of the softening back of the big sheet glass of side sphere sagging.But this patent still can't well solve the problem that changes the reverse sphere that sharply produces because of sheet glass bight long side direction, can't change glass middle part spherical transition and have some setbacks the situation that optical property is not good.
[summary of the invention]
The purpose of this utility model is to provide a kind of Glass mold, and this mould can be realized the operation of twice brake forming of sheet glass easily.
The utility model is achieved through the following technical solutions above-mentioned technical problem: a kind of Glass mold comprises: a pedestal; One shaping frame, this shaping frame is fixed on this pedestal, has a shaping glass sheets surface on it, it comprises that a pair of on the long side direction of being positioned at that is fixed on the pedestal decide forming supporter, and a pair of moving forming supporter that is hinged on the pedestal, this moving forming supporter nestles up to be decided forming supporter and is installed in the two ends of deciding forming supporter respectively; And a premolding frame, this premolding frame comprises that two pairs evenly are arranged on the premolding limit that this decides the forming supporter both sides, and the outboard end on this premolding limit is articulated on this pedestal, and the medial extremity on this premolding limit links to each other with the moving forming supporter of this shaping frame.
Should move an a pair of flank and the balance flank that forming supporter comprises a minor face, is fixed in the minor face two ends, this balance flank comprises a rock arm and a gravity drop hammer, and this rock arm one end is fixed in this minor face end, and the other end is a free end, which is provided with a gravity drop hammer.
The middle part of this rock arm is hinged on this pedestal, and this rock arm overturns around a pin joint.
Fix a link gear on the free end of this rock arm, this link gear comprises be fixedly connected second connecting parts that is provided with screw thread on this first connecting parts of first connecting parts, which is provided with screw thread, this first connecting parts is fixed on the free end of this rock arm, and this second connecting parts is connected in this premolding limit.
Offer a chute on the medial extremity of this rock arm, this second connecting parts passes this chute, and this second connecting parts is closing on chute each sheathed nut of position of both sides up and down.
This rock arm is hinged with hook-shaped pendulum handle in the outer lower portion near this pin joint, corresponding to this hook-shaped pendulum handle one clasp is set on this pedestal.
This rock arm is offered a threaded hole at the outer fix place that is positioned at this gravity drop hammer, and this threaded hole inside is provided with one and regulates bolt, and this pedestal is provided with a banking stop in the stroke lower position of regulating bolt.
The advantage of the utility model Glass mold is: can obviously reduce the sphere in the sheet glass concentric reducer edge extent, improve the problem that the bigger sheet glass concentric reducer spherical transition of sphere has some setbacks, make sphere become arch by waviness, changed the not good present situation of sheet glass middle part optical property simultaneously, and for having played the good effect of improving because of the sheet glass long side direction sharply changes the problem that produces the reverse sphere in bight, alleviated mold-mart by premolding, improve the product appearance quality, and simple structure, be convenient to make maintenance, reduced production cost.
