Embodiment

The utility model comprises pinion and rack, two tooth bars are linked in the chute movingly, two tooth bars respectively with two toothing, gear is fixed on the longitudinal axis, the longitudinal axis is enclosed within on two bearings, bearing is contained on the bearing support, bearing support is fixed on the frame, concrete structure is: drive-motor 1, Rodless cylinder 2, the crowngear pair of the separable engagement of a pair of coaxial inner conductor (outer crowngear 3, interior crowngear 10) is as clutch coupling, one cover worm and gear transmission pair 4 and two sleeve gear tooth bar lifting pairs 5, horizontal transmission shaft 6, longitudinal drive shaft 12, universal coupling 7, elevating bracket 9 and two slip push rods 8 etc.As shown in Figure 1, Rodless cylinder 2 is fixed on the outside, furnace wall, and drive-motor 1 is contained on the slide block 11 of Rodless cylinder 2, crowngear 3 and interior crowngear 10 are meshing with each other outside after Rodless cylinder 2 is squeezed into (slide block 11 is moved to the left), drive-motor 1 rotates then, by horizontal transmission shaft 6 and universal coupling 7 transmission of power to the worm screw of worm and gear 4, drive worm gear, and worm gear is by the gear of longitudinal drive shaft 12 synchronous driven gear tooth bar lifting pairs 5, gear promotes tooth bar, just can rise or descend with tooth bar elevating bracket 9 that connects and the slip push rod 8 that is contained in 9 li of elevating brackets like this.Because supporting mechanism is (envrionment temperature height) in stove, and drive-motor can't bear high temperature, can only be contained in stove outer (heat insulation), but also need have Design on thermal insulation by the furnace wall.The structural requirement of motor coupler is more special like this, accurately transferring power, engagement quickly or separation again.Therefore the design adopts the separable engagement crowngear of a pair of coaxial inner conductor (interior crowngear, another outer crowngear, become negative and positive to cooperate) as clutch coupling, but this is to crowngear both automatic centering when being required to mesh, again because of the mutual interlock of tooth transferring power reliably.Drive-motor 1 is fixed on the slide block 11 of Rodless cylinder, and when a pair of crowngear of needs was meshing with each other, Rodless cylinder 2 was thrown into inside and outside

crowngear

10 and 3 is in contact with one another, and can transferring power.Otherwise slide block 11 returns of Rodless cylinder 2 separate inside and outside

crowngear

10 and 3.

Again because this equipment totally four dollies, glass that can the continuous production different varieties, every dolly all has a cover supporting mechanism, so the side that promotes before drive-motor is contained in respectively and the body of heater side of two heating zone.Same dolly is in operational process, can realize " relay " function, promptly by special electric and Machine Design, make dolly in operational process, its push rod position can be maintained and remember, when waiting to run to next heating zone, mechanism can be dynamically connected up certainly, automatically the push rod height is controlled according to the program of setting again, be need not to reset again or adjustment again, guarantee the continuity of glass ware forming process.

Need to prove, because the auto-lock function of worm and gear 4, can not cause push rod descend (still support glass remains on original position) after making two

crowngears

10,3 separate because of the deadweight of weight of glass and elevating bracket 9 and push rod 8 etc.

As shown in Figure 4, glass 13 is placed on baking bending mould 14 (mould be contained in an independent box-shaped dolly on), and afterwards, elevating bracket 9 and slip push rod 8 have been raised to a high position, and slip push rod 8 is held the middle part of glass, prevent because of unsettled fracture the in glass middle part.After elevating bracket 9 and slip push rod 8 rose to the desired position, Rodless cylinder 2 got that crowngear 10 and outer crowngear 3 separate in (slide block 11 moves right) back.As shown in Figure 1, when dolly enters the heating zone, after glass is heated, progressively crooked.This moment, Rodless cylinder 2 was squeezed into (slide block 11 is moved to the left)

interior crowngear

10 and 3 engagements of outer crowngear, and drive-motor 1 drives elevating bracket 9 and slip push rod 8 descends gradually, pastes mold forming up to glass.After glass pasted mold forming, elevating bracket 9 and slip push rod 8 were in low level, after treating to paste mould fully, elevating bracket 9 and slip push rod 8 drop to extreme lower position, glass 13 has been left at the top of slippage push rod 8, and as shown in Figure 5, the top of slippage push rod 8 and the distance of glass are L.Rodless cylinder 2 is got (slide block 11 moves right) then, and interior crowngear 10 and outer crowngear 3 are separately.

Another Principle of Mechanical Designing of the present invention is, the auto-lock function of worm and gear, crowngear 10 and can not cause 8 declines of slip push rod because of the deadweight of weight of glass and elevating bracket 9 and slip push rod etc. after outer crowngear 3 separates in this function makes, thereby the position of push rod is maintained, measurement encoder and controller by particular design can get off position memory, are convenient to carry out " relay " control.

As shown in Figure 3, slip push rod 8 can be according to the position of width manual regulation two bars of glass.

As shown in Figure 1, the worm screw decentraction of the shaft of drive-motor 1 and worm and gear 4, but utilize the function of universal coupling 7, and assist in horizontal transmission shaft 6, make drive-motor 1 and the transmission of power of worm screw be achieved.
