Detailed description of the invention
Core of the present invention is to provide a kind of carbide alloy casting windshield wiper device, and this device can effectively reduce cooling water to be affected the cold cracking of duralumin, hard alumin ium alloy ingot casting.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the structural representation of a kind of detailed description of the invention of windshield wiper device provided by the present invention, Fig. 2 is the simplification structural representation of windshield wiper device provided by the present invention, and Fig. 3 is the structural representation of windshield wiper device pneumatic circuit provided by the present invention.
In this embodiment, carbide alloy casting windshield wiper device provided by the present invention, comprise wiper 1, for control wiper 1 movement cylinder 2 and be connected with wiper 1 for the logical compressed-air actuated blowing nozzle 9 in ingot casting surface, wiper 1 can be square tabular, the centre position of wiper 1 is provided with the hollow space inserted for ingot casting, wiper 1 is installed with the sealing gasket 7 that can contact with aluminium alloy cast ingot face seal.
Because the temperature of ingot casting is higher, require higher to the resistance to elevated temperatures of sealing gasket 7, fluorubber is the best elastomer of current high-temperature resistant result, and therefore sealing gasket 7 can select thermostable fluorine rubber.
This device controls the movement of wiper 1 by cylinder 2, make wiper 1 tightr with the laminating on ingot casting surface, in addition, by installing thermostable fluorine rubber on wiper 1, sealing between wiper 1 and ingot casting is significantly improved, cooling water effectively can be avoided to flow into the bottom of ingot casting, make ingot casting produce cold crack.
This device also by installing blowing nozzle 9, making the water droplet being attached to ingot casting surface be blown away, not only effectively avoiding the impact of residual water droplet on ingot casting, and blowing nozzle 9 can also utilize compressed air to realize the effect of Physical temperature-lowering to ingot casting surface.Blowing nozzle 9 can pass through metal snake leather hose 8 transporting compressed gas body, because ingot casting surface is higher, adopts metal snake leather hose 8 transport of compressed gas that pipeline can be avoided to be damaged by aluminium liquid, ensures the reliability of transporting gas.
In addition, in order to the better globule by ingot casting surface is cleaned out, the number of blowing nozzle 9 can be multiple, and it is evenly distributed along the circumference of ingot casting, multiple blowing nozzle 9 is simultaneously to the logical Compressed Gas in ingot casting surface, the globule that can realize ingot casting surface blows clean simultaneously, and the time avoiding ingot casting different surfaces to flow away due to cooling water is different and the cold cracking difference that causes, ensures the uniformity of ingot casting performance everywhere.
Can also blowing nozzle 9 be fixed on fixing swash plate, then fixing swash plate is connected with wiper 1, fixing swash plate better can be played a supporting role to blowing nozzle 9, simultaneously, fixing swash plate can make the angle between blowing nozzle 9 and ingot casting be between 30 ° to 60 °, certainly, the angle between blowing nozzle 9 and ingot casting is arranged also can by fixing swash plate.Above-mentioned setting, can make blowing nozzle 9 need set angle according to different, to realize different coolings or other effects, operates more flexible.
Further, wiper 1 comprises two large faces of wiper 3 and two little faces 4 of wiper, and the two ends of cylinder 2 are connected with a large face 3 of wiper respectively, and the large face of wiper 3 can drive synchronous the moving to close or away from ingot casting direction in the little face of wiper 4.
Above-mentioned setting can realize the movement in the large face 3 of wiper by cylinder 2, when the large face 3 of wiper is in the process of the direction movement near ingot casting, the large face of wiper 3 can drive the little face 4 of wiper to the process near ingot casting movement simultaneously, realize the large face of wiper 3 and the little face 4 of wiper to fit with the intimate surface of ingot casting simultaneously, after the cooling of ingot casting terminates, cylinder 2 drives the large face 3 of wiper away from while ingot casting, the large face of wiper 3 can drive again the little face 4 of wiper to move to the direction away from ingot casting, is convenient to the dismounting of wiper 1.
In addition, be positioned at the large face of wiper 3 and be provided with radian with the sealing gasket 7 of wiper little face 4 intersection, make to be positioned at sealing gasket 7 on the large face of wiper 3 and the sealing gasket 7 be positioned on the little face 4 of wiper for ingot casting for seamlessly transitting, so arrange and the large face of wiper 3 can be avoided to produce gap with the intersection in wiper little face 4, and then can effectively avoid cooling water along the intersection slit flow in the large face of wiper 3 and the little face 4 of wiper to the bottom of ingot casting.
Further, large face 3 can be provided with bearing pin with wiper, and the little face 4 of wiper is provided with the rectangular recess inserted for bearing pin, the bearing of trend angle at 45 ° in the bearing of trend of groove and the large face of wiper 3.When the large face 3 of wiper is moved to the direction near ingot casting, the bearing pin that the large face of wiper 3 is installed can move in the groove in the little face 4 of wiper, the little face 4 of wiper is moved to the direction near ingot casting simultaneously, realize the large face of wiper 3 and the little face 4 of wiper to fit with ingot casting simultaneously, avoid ingot casting in the process of cooling, cooling water flow drops down onto bottom ingot casting.
Except above-mentioned setting, this windshield wiper device can also comprise the suspension bracket 5 for making wiper 1 hang, and adopts chain to be connected between suspension bracket 5 with wiper 1.The number of the suspension bracket 5 be connected with each wiper 1 is generally 4, arranging of suspension bracket 5 can make wiper 1 be suspended on around ingot casting, not only avoid wiper 1 to be directly installed on crystallizer to make crystallizer impaired, and the replacing of more convenient wiper 1 and maintenance.In addition, suspension bracket 5 also can be supported by support 6, support 6 is the square structure of hollow, the hollow space of support 6 is corresponding with the hollow space of wiper 1, make ingot casting can put into the hollow space of wiper 1 and support 6 accurately, arranging of support 6 can make different suspension bracket 5 be in same height, and then ensures the horizontal positioned of wiper 1.
Need illustrate time, windshield wiper device provided by the present invention is generally used in the casting process of hard aluminium alloy, certainly, also may be used in the casting process of other carbide alloy.
Above carbide alloy casting windshield wiper device provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.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 improve and modify and also fall in the protection domain of the claims in the present invention.
