Description
Technical field
The invention belongs to the technical field of the reshaping of first type glass.
Background technology
In the past, in the case where carrying out bending machining to windshield, mainly using following processing method：By windshield
Defined size shape is cut into, and on the bending mould being positioned in the heating furnace of atmospheric environment, is heated to energy
Enough carry out the softening temperature of the glass plate of bending forming（It is different because of glass material, but generally 550 DEG C~700 DEG C left sides
It is right）, thus, firmly pulled by conducting oneself with dignity or clamping plate glass both sides, plate glass is deformed into the shape along bending mould
Shape.
However, existing heating furnace more typically heats from down to up to glass, cause glass heating surface uneven,
Thus cause the time of heating to increase, waste the more energy, processing efficiency is low；In addition, needed using bending of conducting oneself with dignity
The time treated is longer, less efficient；And because the glass after heating is softer, plate glass both sides are clamped using clamping plate and pulled at
Dynamic method, can make the discontinuity of glass, and the part stress of glass clamping is larger, it may appear that the situation of flattening, influences curved
The qualification rate that bent glass makes, reduce the processing efficiency of glass.
The content of the invention
The invention is intended to provide a kind of windshield pane bending apparatus, bent with solving windshield in the prior art
Form the problem of efficiency is low.
In order to achieve the above object, base case of the invention provides a kind of windshield pane bending apparatus, including

State bending mould side and be fixedly connected with some vertical poles, air bag, the air bag are removably connected with above the pole
It is oppositely arranged with the flexure plane of bending mould；The bending mould is internally provided with venting cavity, the first branch pipe, the second branch pipe and
Three branch pipes, venting cavity upper end connect with passage, and venting cavity lower end connects with the first branch pipe upper end, and the first branch pipe upper end connects
M type airway tubes are connected to, the gas port relative with the first branch pipe is offered at the top of M types airway tube, bullet is provided with the gas port
Property part, marking pen is connected with above elastic component, marking pen upper end is relative with passage, and the first branch pipe lower end is connected with valve,
The first branch pipe side wall is connected with tracheae, and tracheae connects with air bag；The valve can control the first branch pipe and the second branch pipe or
3rd branch pipe connects, and second branch pipe is connected with hot gas room, and the 3rd branch pipe is connected with cold air chamber.
The technical principle of this programme is：Windshield to be processed is placed on bending mould working face, control valve,
First branch pipe is connected with the second branch pipe, the hot gas in hot gas room enters in the first branch pipe with the second branch pipe, and flows to M type air guides
Pipe, flow into venting cavity, hot gas is partly into venting cavity, and discharged from passage, another part hot gas is then by tracheae
Into in air bag, it is big that air bag is heaved into support.The hot gas of passage discharge heats to lower glass surface, while supports big air bag and glass
Glass contact can also transferring heat energy to glass top surface so that Glass Transition, supportting big air bag has certain elasticity, can be with
It is bonded, contacts comprehensively with glass top surface, and then pressure is applied with to glass, accelerates the glass after softening and pasted with bending mould
Close, so as to realize the bending to glass.After glass bending shaping, control valve, close the second branch pipe and lead to hot gas, treat in air bag
Hot gas discharge, and when single unit system temperature is reduced to room temperature, control valve, the first branch pipe of control connects with the 3rd branch pipe, enters
And the cold air in cold air chamber can be subjected to cooling treatment to glass after bending, so as to realize the cooling forming of glass.In addition,
Hot gas, because flow velocity is very fast, can jack up elastic component upwards, and then make the mark above elastic component when entering M type airway tubes
Pen jacks up upwards, and marking pen enters passage and made marks on glass, and operator correspondingly finds glass by the mark on glass
The center of glass, it is easy to carry out next step processing to glass.
Beneficial effect：1st, the technical program is heated comprehensively up and down by bending mould and air bag to glass, can make glass
The comprehensive thermally equivalent in surface, and then be easy to make Glass Transition, the time of heating is relatively reduced, has saved the energy, improves and adds
Work efficiency rate；2nd, big process is supportted using air bag, air bag is bonded comprehensively with glass, and is pressed down against glass, glass is compared and leans on certainly
Bend again, improve processing efficiency, avoid glass surface and the problem of discontinuity occur；3rd, can by control valve
The conveying of hot gas or cold air is controlled, consequently facilitating making glass bending, is easy to glass cooling forming afterwards, can be realized simultaneously pair
Two processes of glass bending and shaping, improve processing efficiency；4th, using hot gas or cold air when entering M type airway tubes, to bullet
The pressure of property part, makes marking pen be marked heart position in glass, personnel easy to operation find the center of glass, enter one
Step carries out other process operations to glass.The technical program efficiently solves windshield in the prior art and processed in bending forming
The problem of efficiency is low, operating personnel only need control valve, convenient operation, and glass bending effect is good, is easy to glass
Shaping, it is practical.
Preferred scheme one, as the further optimization to base case, the air bag surface relative with bending mould is opened
Provided with some through holes；The hot gas being passed through in air bag can be heated through through hole to glass top surface, or cold air is carried out
Cooling, control is sufficiently large into the gas velocity of air bag, so that after air bag support is big, then discharged from through hole.
Preferred scheme two, as the further optimization to preferred scheme one, supporting plate is also associated with the pole, it is described
Supporting plate is located at the top of air bag；After gas is filled with air bag, supporting plate can stop that air bag expands upwards, air bag be supportted big
Process serve the effect of guiding, make Directional Extension of the air bag towards bending mould, and then be easy to make air bag comprehensive with glass
Fitting, extruding glass gluing bending mould top.
Preferred scheme three, as the further optimization to preferred scheme two, the flexibility of the supporting plate and bending mould
It is identical；The flexibility of supporting plate is identical with bending mould design, when air bag support is big, it is easy to supporting plate preferably to lead air bag
To, air bag is formed the structure similar to punch-pin and cavity plate with bending mould, accelerate air bag and be bonded comprehensively with glass, and to glass
Apply downward pressure, make glass bending.
