The connection other end is set in the hollow connecting tube 29 of 34 periphery of sliding block 30 and the second lead screw, 30 shape of sliding block and hollow connecting tube 29
It is corresponding square close to 6 one end of the second gearbox, it can itself generation when the second lead screw 34 rotates of anti-limited slip block 30
Rotation.It is equipped with close to one end of the second gearbox 6 for avoiding sliding block 30 from hollow connecting tube 29 in hollow connecting tube 29
The gland 31 of slippage, 29 inner cavity of hollow connecting tube middle part be equipped be set in the pressure sensor 33 of 34 periphery of the second lead screw with
And for avoiding pressure sensor 33 towards the limited step moved opposite to each other in 6 direction of the second gearbox, on the second lead screw 34
Spring 32 is equipped between pressure sensor 33 and sliding block 30.Through equipped with for hollow connecting tube on the side wall of furnace body framework
Second guide sleeve 28 of 29 slidings, hollow connecting tube 29 are slidably located in the horizontal direction in the second guide sleeve 28, the second lead screw
34 rotations can be moved left and right with movable slider 30, and then hollow connecting tube 29 is driven to move.As shown in figure 8, sliding block 30 moves right
When hollow connecting tube 29 can be driven under the action of gland 31 and pressure connecting rod 9 is whole moves to right, and then make compression bar 10 far from mould
Tool 20.When sliding block 30 is moved to the left, 32 compressive deformation of spring can be made under the action of limited step, under the action of rock deformation pressure
Hollow connecting tube 29 and pressure connecting rod 9 is whole moves to left so that compression bar 10 is close to mold 20, so as to waiting for after heating and softening
The edge of processing glass 17 is fitted closely with mold 20.The coefficient of elasticity design of spring 32 has with 17 compression situation of glass to be processed
It closes, ensures to continue to press after compression bar 10 touches glass 17 to be processed, at this time compression bar 10, hollow connecting tube 29 and overload protection machine
The movement of structure stops, and the rotation of third driving motor 5 can to the left be compressed with the continuation of movable slider 30, and pressure sensor 33 is not up to
Before the maximum pressure of setting, spring 32 will continue to compressive deformation, provide enough pressure to compression bar 10 so that glass to be processed 17
Edge be close to 20 good deformation of mold；When pressure sensor 33 reaches setting pressure（Glass 17 to be processed reaches permission at this time
The limit of compression）, the signal of pressurization can be stopped to system feedback, system can stop the rotation of third driving motor 5 and embrace in time
Lock, finally 10 third driving motor of compression bar, 5 counter-rotating belts dynamic pressure bar 10 leaves glass after 17 hot bending of glass to be processed.
In a preferred embodiment of the invention, bottom plate 7 is spliced by polylith stripe board, arbitrary two pieces of adjacent bar shapeds
Expansion clearance is equipped between plate；Supporting rod 19 is spliced by more first quarter butts, arbitrary two the first adjacent quarter butts it
Between be equipped with expansion clearance；Compression bar 10 is spliced by more second quarter butts, is all provided between arbitrary two the second adjacent quarter butts
There is expansion clearance, avoids bottom plate 7, supporting rod 19 and compression bar 10 and deform when heated, be unfavorable for the essence of tool and mould 20 to be added
Determine position, support and pushing.First rotating shaft 16, the second shaft 26 and third shaft 27 are segmented, pass through shaft coupling between each section
Device connects.
The specific process of the present invention is made as follows：Original state by glass 17 to be processed as shown in Figure 1, be placed horizontally at mold
On 20, the compression bar 10 of 20 both sides of mold is outer respectively at this time moves, and the middle part of glass 17 to be processed is waited for by the top braces of mold 20
The edge of processing glass 17 is supported by two supporting rods 19, and the lifting heating tube 18 on top is horizontal positioned.When glass is close
Supporting rod 19 slowly moves down under the action of the second lifting gear when softening temperature, while top faces glass to be processed
17 liang of side position lifting heating tubes 18 ensure that the distance apart from glass 17 to be processed is constant in slowly moving down for the first lifting gear.
When both sides are close to submissive mold 20 under the action of own wt for glass 17 to be processed, supporting rod 19 is moved to furnace body frame 12
Bottom, both sides compression bar 10 moves inwardly under the action of push-pull device at fixed slowly compresses glass 17 to be processed and persistent pressure makes to wait for
Processing glass 17 well fits perfectly on mold 20, and when the pressure sensor 33 of overload protecting mechanism reaches setting pressure, third is driven
Dynamic motor 5 stops operating and band-type brake, final molding state as shown in Fig. 2, 17 complete docile of glass to be processed on mold 20, most
Make to move to take out formed glass outside compression bar 10 by the reversion of third driving motor 5 afterwards.
