Accompanying drawing explanation
Fig. 1 is the synoptic diagram that the situation of chatter occurs because of roll-in and air knife etc. the band steel of expression through melting mouth.
Fig. 2 be represent according to a preferred embodiment of the invention for be with steel to bend or chatter time maintain the synoptic diagram of device of the planeness of band steel.
Embodiment
Belt steel flating degree holdout device according to the present invention can implement various change, and can have various embodiments, and accompanying drawing is passed the imperial examinations at the provincial level and exemplified specific embodiment, for being described in detail to this.But and not intended to be limits the invention to specific example, should be understood to be contained in all changes of technological thought of the present invention and technical scope, equipollent or surrogate and also all comprise.
Below, describe in detail according to belt steel flating degree holdout device of the present invention with reference to accompanying drawing.
Fig. 2 be represent according to a preferred embodiment of the invention for be with steel to bend or chatter time maintain the synoptic diagram of device of the planeness of band steel.
Belt steel flating degree holdout device according to the present invention comprises the cushion part 11 of Porous, chamber portion 12 and compressor 60.
Porous cushion part 11 is formed with multiple hole on surface, by these multiple holes, air 1a is sprayed to band steel 1.
Form faced by Porous cushion part 11 is mutual by a pair, as shown in Figure 2, band steel 1 is between a pair Porous cushion part 11.But be formed with fused zinc (Zn) in the surface treatment of band 1, Porous cushion part 11 is set to be separated by predetermined distance with the surface with steel 1 to avoid contacting with being with steel 1.
The material of Porous cushion part 11 is not limited, but considers the characteristic of the operating environment that can be exposed to heat of high temperature, preferably adopts the material with thermotolerance.
Cushion part 11 sprays air at the both sides facing tape steel 1 of band steel 1, and such air plays and holds on band steel 1 to prevent chatter or bending effect, therefore there will not be the chatter 6 of band steel 1 or bending.
Chamber portion 12 is attached at cushion part 11 and fixed-bearing portion 11.Cushion part 11 is configured to Porous and air is sprayed to band steel 1, and the air that cushion part 11 is sprayed will be supplied by chamber portion 12.
Compressor 60 as the one of compression set (compressor), for providing pressurized air to chamber portion 12.Compressor 60 can regulate compressed-air actuated intensity of compression certainly.
Compressor 60 has thermotolerance to adapt to the operating environment of zincincation, by considering degree of compressed-air actuated pressure etc. and appropriately selecting the common compressor 60 that utilizes in industry, omission is illustrated this.
Belt steel flating degree holdout device according to the present invention can also comprise support portion 20, pressure warning unit 50 and control part 40.
Support portion 20 is attached at the side in chamber portion 12, as shown in Figure 2, is preferably placed at the outer side (not with the side faced by band steel 1) in chamber portion 12, and can retreats towards band steel direction, thus can regulate cushion part 11 and the standoff distance being with steel 1.
Pressure warning unit 50 is positioned at the inside in chamber portion 12, thus is connected and the air pressure of inside, sensing chamber portion 12 with inside, chamber portion 12.Pressure warning unit 50 also has thermotolerance to adapt to the operating environment of zincincation, and appropriately selects the simple manometer 50 that utilizes in industry by considering the scope of pressure that will sense in this chamber portion 50 etc., omission is illustrated this.
Control part 40 can make support portion 20 fully retreat according to the state of operation control part 40 of operation subtend band steel for network operator, thus prevent the problem of abnormal condition, and receive the internal air pressure information in chamber portion 12 from pressure warning unit 50, thus support portion 20 is controlled into regulating cushion part 11 and the standoff distance being with steel 1.
Such as, if the air pressure of inside, chamber portion 12 is weak, then make the standoff distance between cushion part 11 and band steel 1 narrow by controlling support portion 20, on the contrary, if the air pressure of inside, chamber portion 12 is strong, then the standoff distance between cushion part 11 and band steel 1 is made to broaden by controlling support portion 20.
Belt steel flating degree holdout device according to the present invention additionally can also comprise the relief valve of the air being fed to chamber portion 12 for manual opening and closing.
By relief valve, manual opening and closing can flow into from compressor 60 towards the air in chamber portion 12, and very also manually can block the discrepancy of air moment.
In the term that this specification sheets uses, as long as the statement of odd number is not clearly interpreted as other implications and is just construed as the statement comprising plural number on context, and terms such as " comprising " only for represent there is setting feature, number, step, operation, integrant, parts or its combination, should be understood to not get rid of other features one or more, number, step, operation, integrant, parts or its combination existence or can additivity.
The item of interest field of the present invention described in claims is determined, if there is use bracket in claims, it is not intended to limit washability, but for recording clear and definite integrant, the record in bracket also should be interpreted as necessary integrant.
