Abstract
The invention provides a production method for high-speed train front windshields capable of being rapidly replaced and a front windshield produced by the scheme. The invention is characterized in that the production method includes the following steps: mounting holes are drilled on the circumferential edge of a piece of inner glass; T-shaped bolts are mounted in the holes, the heads of the bolts are in the glass, and the rods of the bolts are outside the glass; a piece of outer glass, a rubber strip and the inner glass are cleaned; in the step of assembly, the outer glass, the rubber strip and the inner glass which are cleaned are sequentially assembled; vacuumization is carried out in order to exhaust the air; preheating and prepressing are carried out, so that the two pieces of glass and the rubber strip are preliminarily stuck together; constant-temperature pressing is carried out, so that the outer glass, the rubber strip and the inner glass are stuck together. The invention has the advantages that: when the high-speed train front windshield needs to be replaced, the front windshield is convenient to mount and dismount, the time needed by replacement is greatly shortened, moreover, the structure of the high-speed train front windshield capable of being rapidly replaced is simple, and the production cost is low.
Description
Technical field
The present invention relates to a kind of high speed train windshield, be specially a kind of windshield that can quick-replaceable high speed train windshield production method and produce by this scheme.
Background technology
High speed train overall trip speed is per hour more than 200 kilometers, vehicle body adopts airflow design, particularly headstock is generally bullet-shaped, windshield not only performance requriements is high, and face shaping is special, for reducing windage and guaranteeing firm, sealing effectiveness, install is generally by the direct bonding of polyurethane adhesive or by after being combined with aluminum alloy window frame, by being coated with the mode of sealant, identical to guarantee with car body panel beating again, meet the technical requirements of seamless assembling.Because having determined current high speed train windshield, mounting means generally can not carry out quick-replaceable, gear glass breakage after change time, difficulty glass being disassembled with the apparatus such as perching knife, iron hammer is very large, will remove cullet and old polyurethane adhesive after dismounting, time-consuming bothersome; After removing work completes, also need to be bonded together with new polyurethane adhesive and vehicle body, and the curing time that needs 5-6 days of polyurethane adhesive is waited polyurethane adhesive to solidify rear train completely and could run, glass of general replacement needs the time of one week again.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide one can quick-replaceable high speed train windshield production method, can shorten the replacing time of windshield, reach quick-replaceable object.
Another object is to provide a kind of high speed train windshield.
The present invention realizes like this
One can quick-replaceable high speed train windshield production method, it is characterized in that comprising the following steps:

The specific embodiment
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
One can quick-replaceable high speed train windshield production method, carries out according to following steps:
(1) edge of interior sheet glass is bored to upper mounting hole;
(2) T-shaped screw is installed in hole, screw head is in glass, and body of screw portion is outside glass;
(3) externally sheet glass, film and interior sheet glass clean;
(4) close sheet: outer sheet glass, interior sheet glass and film are assembled successively, and outer sheet glass aligns overlapping with interior sheet glass, cuts off the unnecessary film of glass periphery;
(5) by vacuumizing rubber band on the glass sock assembling, glass is carried out to cold-draw, the vacuum keep of vacuum air storage tank is at 0.09MPa-0.1MPa, and the cold-draw time is not less than 5min, to discharge the air between glass and film;
(6) glass is carried out to preheating precompressed, when preheating precompressed, ambient temperature is set between 120 ℃-150 ℃, and vacuum pressure settings, at 0.09MPa-0.1MPa, tentatively sticks together film and glass.
(7) preliminary bonding glass after preheating precompressed is put into and in autoclave, carried out High Temperature High Pressure processing, first the temperature in autoclave is risen to 50 ℃-80 ℃, to autoclave inflating pressure, when still internal gas pressure reaches 0.7MPa-0.8MPa, suspend the pressurization to autoclave, make the air between glass sandwich overflow glass; After reaching 135 ℃-150 ℃, temperature in the kettle stops heating, keep temperature constant state, autoclave is carried out to defuelling pressurization, still internal pressure stops pressurization after reaching 1.1MPa-1.25MPa, make to remain in still 135 ℃-150 ℃ of temperature, pressure 1.1-1.25MPa, in still under constant temperature and pressure state after 1h-1.5h, start cooling in still, when temperature is down to 50 ℃, in still, start step-down, until after air emptying, glass is taken out in still, by this step process, film and glass are firmly sticked together, also improved product strength.
By the aforementioned high speed train windshield can quick-replaceable train windshield production method obtaining, comprise outer sheet glass 1 and interior sheet glass 4, outer sheet glass 1 does not arrange mounting hole, interior sheet glass 4 edges are provided with mounting hole, are illustrated in figure 1 the front view of windshield, and T-shaped screw 3 is set in hole, outer sheet glass 1 is bonding by film 2 with interior sheet glass 4, screw head is embedded in glass, and body of screw portion is outside glass, and windshield is along the cutaway view of A-A line as shown in Figure 2.
When installation, rubber seal 5 is assembled on high speed train vehicle body 6, with equipment such as suckers or manually windshield is placed on sealing member 5, then assemble spring washer 7 and nut 8, glass is fixedly mounted on vehicle body 6, finally between vehicle body 6 and glass, stamp sealant 9, as shown in Figure 3; Rubber seal can be also other sealing member with vibration damping, sealing function.
In the time that the breakage of generation train windshield need to be changed glass, cut open the sealant between windshield and car body, shed nut and spring washer and just can directly dismantle windshield, shorten significantly the required time of windshield of changing, and the screw that outer plate glass outer side does not protrude do not have mounting hole yet, leak tightness and smooth in appearance are guaranteed.
Above the present invention is described in detail.Herein principle of the present invention and embodiment are set forth, above explanation is just for helping to understand core concept of the present invention.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
