Embodiment
below in conjunction with accompanying drawing, technical scheme of the present invention is further elaborated.
shown in Fig. 1-2, above-mentioned a kind of heat-bending glass mould, comprises the carrier 1 for the treatment of heat-bending glass 3 for carrying, is located in this carrier 1 for the hot bending speed of sight glass 3 and limits the stopper 2 of its hot bending amount of deflection.
carrier 1 is hollow structure and opening up, and this carrier 1 is by the periphery bearing glass 3 of upper surface.In the present embodiment, glass 3 is rectangular shape, and 3 one groups of relative limits of glass are simple supported edge 31, and this simple supported edge 31 is shelved on carrier 1, glass 3 another to organize relative limit be free edge 32, this free edge 32 is vacant state.
in the present embodiment, carrier 1 upper surface is provided with and supports hypotenuse 11, one group of simple supported edge 31 of glass 3 is shelved on this support hypotenuse 11, by the setting of this support hypotenuse 11, make this heat-bending glass mould can in the time of heating, not interfere freely softening of glass 3 to be sunk, also can support preferably this glass 3 simultaneously.
stopper 2 comprise be located at carrier 1 inside for support glass 3 after hot bending strut member 21, be fixed on the measurement backboard 22 that vertically distributes on strut member 21, vertically slide be located at pointer 25 that the depression bar 23 measured on backboard 22, being located at of rotating measure on backboard 22, be located at and measure 22 scales 26 that are positioned in pointer 25 one end rotary motion trace on backboard, the bottom of depression bar 23 is pushed against on the other end of pointer 25, the projection of depression bar 23 in the vertical directions is positioned at the center of glass 3, and the projection of strut member 21 in the vertical directions is through the center of glass 3.
the distance of these strut member 21 in the vertical directions and this glass 3 is the amount of deflection of needed glass 3 in hot bending process, and this strut member 21 can be according to moving up and down and be fixed on corresponding position in the carrier 1 that do not coexist of institute's processed glass 3 amounts of deflection.
wherein, pointer 25 is provided with for depression bar 23 bottoms and snaps in the groove for preventing that depression bar 23 from skidding off from pointer 25.
what pointer 25 rotated by the first rotating shaft 27 be located at measures on backboard 22, is also provided with at pointer 25 and measures the packing ring between backboard 22 in the first rotating shaft 27, the resistance can reduce like this pointer 25 and rotate time.The lenth ratio of two sections that pointer 25 is divided into by the first rotating shaft 27 is larger, by this setting, in the time that the shorter one end of depression bar 23 and length moves down small distance, the scale that the one end that can significantly grow from length is pointed to is observed out this small change in displacement.
measure on backboard 22 and be fixed with the sliding sleeve 24 sliding for depression bar 23, depression bar 23 upper ends are provided with the block piece 28 that stops depression bar 23 to skid off from sliding sleeve 24.When block piece 28 slides into conflict sliding sleeve 24 top edge, the height of block piece 28 is lower than the height of strut member 21.The block piece 28 here can be discoid, by the setting of this block piece 28, can expand the contact area of depression bar 23 and glass 3, avoids the excessive infringement that 3 types of glass are caused of local pressure in hot bending process.When this glass 3 hot bending, block piece 28 is flushed with the height of strut member 21 to it by the downward straightening of glass 3, can support the glass 3 after hot bending by strut member 21 like this, thereby props up and affect the face of glass 3 type to avoid it to be blocked part 28.In the present embodiment, strut member 21 is therefrom separated, reserve and can be blocked the through hole that part 28 passes.
depression bar 23 comprise slip be located at the first depression bar 231, the bottom measured on backboard be pushed against the second depression bar 232 on pointer 25, for the second depression bar 232 is fixed on to the locking piece 234 on the first depression bar 231.In the present embodiment, the first depression bar 231 has the tube chamber of hollow, what the second depression bar 232 slided is located in this tube chamber, tube chamber offers lock slots 233 vertically, the second depression bar 232 is provided with by this lock slots 233 the second depression bar 232 is locked to the locking piece 234 on the first depression bar 231, and locking piece 234 can be lock screw here.Here can, by regulating the position of relative the second depression bar 232 of the first depression bar 231 to regulate the distance between the first depression bar 231 tops and glass 3, adjust according to the glass 3 of unlike material the different positions that needs to observe control in hot bending process.In general, to exceed the height of strut member 21 be 5mm to 40mm to the block piece 28 on depression bar 23 tops.
in the present embodiment, the weight of depression bar 23 and block piece 28 should be put gently as far as possible, like this in the time that glass 3 hot bendings withstand block piece 28 downwards, even if a small pressure also can make the rotation that pointer 25 is more sensitive, because the pressure between glass 3 and block piece 28 is less, substantially can not cause too much influence to the face type of glass 3 simultaneously.
pointer 25 point on one end of scale 26, slide be provided with slide block 29, be used for preventing in the time of idle state the situation that this one end of pointer 25 upwarps.Accordingly, measure backboard 22 and be provided with the jack-up part that points to scale 26 these one end for jack-up pointer 25, to prevent that pointer 25 is under the effect of slide block 29, after the first rotating shaft 27 is rotated, be vertical direction and distribute.
the concrete working process of setting forth lower the present embodiment below:
first glass 3 is placed on the carrier 1 of glass hot-bending die, in the present embodiment, this glass 3 is rectangular shape, and one group of simple supported edge 31 that glass 3 is relative is placed on the support hypotenuse 11 of carrier 1 upper surface, and another group free edge 32 that glass 3 is relative is vacant state.Regulate the relative position between the first depression bar 231 and the second depression bar 232 to make the block piece 28 of depression bar 23 upper ends exceed strut member 21 between 20mm to 40mm, heat this glass 3, glass 3 gradually hot bending produces amount of deflection, in the time that glass 3 centers touch block piece 28 downwards and it is depressed together, at this moment can point to the speed that this end of scale 26 rotates according to pointer 25 and determine the temperature that how to regulate heating, if pointer 25 rotating speeds are too fast, reducing Heating temperature conflicts on strut member 21 glass 3 stably after hot bending, if pointer 25 rotating speeds are excessively slow, suitable rising Heating temperature is conflicted on strut member 21 glass 3 stably after hot bending, if pointer 25 rotating speeds are steady, keep Heating temperature that glass 3 is conflicted on strut member 21 after hot bending stably.
above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
