Description
Technical field
The utility model relates to a kind of metal material surface treatment unit, relates in particular to a kind of metal material surface cladding apparatus.
Background technology
At present, the zinc pan gas cutter that uses of cold rolling hot dip galvanizing production line is for the production of the attached value appliance plate of height and automobile exterior panel.In process of production, after the steel plate of the high temperature annealing zinc liquid by 450 ℃, zinc pot, directly by zinc pan gas cutter to the surface of steel plate nitrogen-blow, thereby make institute's zinc coating homogenizing of surface of steel plate.But, in actual production process due to air knife 11 width usually all greater than steel plate 12 developed widths, so fringing effect that easily produces air-flow in the dual-side section of steel plate, as shown in Figure 1, can cause the limit section zinc coating of steel plate blocked up, thereby affect quality and the qualification rate of steel plate galvanized product.Secondly, in the winding-up process, collision mutually can occur and produce high frequency noise in the air-flow that air knife blows out beyond steel plate width due to air knife, and that gives the field personnel has healthyly brought certain harm.
At present, domestic also have use with the air knife edge dam mechanism of handwheel position regulator, although it is for preventing that steel plate edge from thickening defective and having certain effect, but when the production unit need to be produced the different in width specification steel plate, need the staff to carry out manually adjustment and the location of baffle mechanism position by the handwheel position regulator.This is not only time-consuming but also require great effort for the staff, and the baffle position bearing accuracy is not high, and online replacing baffle mechanism difficulty is also very large simultaneously.The patent documentation that relates to air knife edge dam mechanism is as follows:
Notification number is CN201376994Y, the day for announcing is on January 6th, 2010, the Chinese patent literature that name is called " air-knife baffle adjusting device " is established and is related to a kind of setting device for air knife, it comprises locating support, slide block, orienting lug, hanger, the position adjustment of its baffle plate mainly relies on the handwheel adjustment to drive the change in location that screw mandrel is realized baffle plate, controls with the distance between steel and baffle plate along position on track by the manual setting roller.Although this setting device is simple in structure, in the difference according to the actual production strip width, need to carries out corresponding manual position adjustment, and the phenomenon of strip running deviation also may occur in actual production often.Do personnel for work, not only manual setting wastes time and energy, it adjusts precision also to need to have higher operant level guarantee, and the position adjustment can only manually be adjusted when producing online, and because envrionment temperature above the zinc pot is higher, long-time online adjustment operation meeting brings certain influence to personnel.
Publication number is CN201250278Y, and in open day on June 3rd, 2009, name is called the Chinese patent literature of " air knife baffle plate device ", discloses a kind of retaining device for air knife, and it comprises: sprung parts, positioning element and baffle body; Sprung parts is provided with gudgeon, is used for being installed on hanger; Positioning element comprises that fixed block and clamping piece are used for fixed dam; Baffle surface arranges the auxiliary zinc pipe that blows and is used for blowing away zinc gray on baffle plate.This retaining device structure is comparatively simple, but because related baffle plate volume is larger, and on baffle plate, the parts such as tracheae are for being fixedly connected with, if so can't change rapidly when baffle plate distortion, the abnormal conditions such as crooked occur in process of production, may cause certain influence to production efficiency.In addition, although the auxiliary zinc pipe that blows of baffle surface setting can blow away with the zinc gray that drops on steel on baffle plate, but in actually operating is produced, air knife winding-up air-flow easily makes the zinc granule of steel edge portion splash in collision process mutually, especially easily stick to baffle edge band corner angle and roughness higher surface, cause baffle surface spray zinc phenomenon to occur.
The utility model content
the purpose of this utility model is to provide a kind of hot-dip galvanized pan air knife edge dam device, this air knife edge dam device is arranged at steel plate both sides along the steel plate width direction, it is improving the inhomogeneity while of surface of steel plate, can also carry out online baffle plate changes and can carry out according to the different steel width the timely adjustment of baffle position, to avoid the defective that artificial on-line control baffle plate is wasted time and energy and performance accuracy is not high, cause the generation of strip running deviation phenomenon, simultaneously, also avoid air-flow that collision mutually occurs and produce high frequency noise, and then provide the Working environment of safety and Health for the field staff.
