Abstract
The utility model relates to a hot-rolled strip steel uncoiler, and belongs to hot continuous rolling strip steel uncoiling checking equipment. The hot-rolled strip steel uncoiler comprises an uncoiler body, wherein the uncoiler body is provided with a supporting roller, a lining plate, an upper shear blade, a lower shear blade and an upper shear blade pressing plate, wherein the lining plate is provided with pulley wheels. Corners of the cross section of the upper shear blade pressing plate are transited through round angles. The pulley wheels are arranged at one end of the lining plate close to a steel coil and at the corners of the lining plate. On the basis of ensuring normal uncoiling check of hot-rolled strip steel, the hot-rolled strip steel uncoiler reduces the contact of the strip steel with the lining plate and the pressing plate of the uncoiler during the uncoiling process, and solves the problem of surface scratching during the coiling checking process of hot-rolled strip steel.
Description
Technical field
The utility model belongs to the hot-continuous-rolling strip steel uncoiling and checks field, specifically a kind of hot-strip uncoiler.
Background technology
Hot-strip production has at a high speed, the characteristics of in enormous quantities, continuity, high yield, the annual production of general hot-strip factory is more than 1,500,000 tons, therefore, in case mass defect occurs, and can not find in time that its quantity economic loss huge, that cause also is huge.Along with the increase of domestic hot-strip output, it is particularly important that the quality of coils of hot-rolled steel quality seems in keen competition, and the uncoiling inspection be control hot-strip quality a kind of the most direct, in time, control device quickly and efficiently.
Coil of strip checks that line is the visual plant of hot-rolled strip production line, capital equipment comprises: carrying roller, a shovel machine, cutter, roller-way etc., its operation principle is: need the coil of strip on uncoiling inspection surface to be transported on the carrying roller by fortune volume dolly, carrying roller rotates, the coil of strip afterbody is opened, afterbody is entered in the gap of lower scissor blade by the guiding of the guiding liner plate on the cutter, pressing plate on the cutter presses down, and band steel afterbody is driven plain, and continues uncoiling to opening length, upper and lower surface is checked, when needing sampling, selected uncoiling length starts cutter cuts off, in the time of need not taking a sample, the counter-rotating carrying roller, the coil of strip of opening is retracted.
Coil of strip is in the process of opening or regaining, and the guiding liner plate of band steel outer surface and cutter is sliding-contact all the time, and there is scuffing to a certain degree in belt steel surface.When downstream user is used coil of strip, need cause the user to use the waste of lumber recovery with scratching the part excision.Along with the steel market situation is increasingly serious, the client has proposed strong objection to the scuffing of coil of strip.The current measure of taking is partly to excise scratching serious uncoiling, has caused a large amount of wastes, has had a strong impact on the hot-strip lumber recovery.Therefore, be badly in need of uncoiler is carried out the equipment component transformation, reduce the scuffing that uncoiling process produces.
The utility model content
The purpose of this utility model is to provide a kind of hot-strip uncoiler, this equipment is guaranteeing on the basis that the normal uncoiling of hot-strip checks, reduced the band steel in uncoiling process with the sliding-contact of equipment, solved the surface tear problem in the hot-strip uncoiling checking process.
The technical scheme in the invention for solving the technical problem is: the hot-strip uncoiler, comprise the uncoiler main body, and the uncoiler main body is provided with carrying roller, liner plate, upper scissor blade, lower scissor blade and upper scissor blade pressing plate, and described liner plate is provided with pulley.
The corner of described upper scissor blade pressing plate section is round-corner transition.
Described pulley is located at described liner plate near an end of coil of strip and the corner of liner plate.
The beneficial effects of the utility model are:
1, the design of uncoiler liner plate is unique, utilize pulley to be directed away the winding steel and enter uncoiler, pulley will be with steel and the isolation of uncoiler liner plate to separate simultaneously, the band steel be contacted by planar slide with the uncoiler liner plate change circular arc rolling contact into, reduce the surface tear of band steel in uncoiling process;
2, pulley is easy to polishing and changes, and is convenient to the maintenance of equipment, prolongs liner plate service life.
3, the corner of upper scissor blade pressing plate section is round-corner transition, will be with steel to contact with the upper scissor blade pressing plate by corner angle contacts and become arc transition, has effectively reduced the surface tear in the removal process after the uncoiling of band steel.
Description of drawings
Fig. 1 is internal structure principle sketch of the present utility model.
Among the figure: 1 upper scissor blade pressing plate, 2 band steel, 3 upper scissor blades, 4 lower scissor blades, 5 liner plates, 6 carrying rollers, 7 coil of strips, 8 pulleys.
The specific embodiment
The utility model will be further described below in conjunction with Figure of description and the specific embodiment:
As shown in Figure 1, the hot-strip uncoiler comprises the uncoiler main body, and the uncoiler main body is provided with carrying roller 6, liner plate 5, upper scissor blade 3, lower scissor blade 4 and upper scissor blade pressing plate 1, and described liner plate 5 is provided with pulley 8.
The corner of described upper scissor blade pressing plate 1 section is round-corner transition.
Described pulley 8 is located at described liner plate 5 near an end of coil of strip 7 and the corner of liner plate 5.
In the time of need carrying out uncoiling inspection surface to coil of strip, coil of strip 7 is transported on the carrying roller 6, carrying roller 6 rotates, coil of strip 7 afterbodys are opened, band steel 2 after opening enters uncoiler by pulley 8 guiding, change contacting of band steel 2 and pulley 8 into by traditional band steel 2 and contacting of liner plate 5, avoided liner plate 5 and be with between the steel 2 sliding friction will be with steel 2 surface tears.When upper scissor blade pressing plate 1 presses down, because the corner of upper scissor blade pressing plate 1 section all is improved to round-corner transition, avoided the corner angle of upper scissor blade pressing plate 1 will be with the problem of steel 2 surface tears, by the improvement of liner plate 5 and upper scissor blade pressing plate 1, effectively reduced the surface tear phenomenon that the band steel occurs in the removal process after uncoiling inspection and uncoiling like this.
Carrying roller 6 is fluid motor-driven, and the phenomenon that do not match appears in two roller speed sometimes, easily causes the contusion between band steel 2 each layers in uncoiling or the wrapup procedure, carrying roller 6 speed regularly should be adjusted check and correction, guarantees the two rollers uniformity of speed in use.
The above, principles more of the present utility model just explain through diagrams, this specification be not be the utility model to be confined to shown in described concrete structure and the scope of application, so every corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
Except the described technical characterictic of specification, all the other technical characterictics are those skilled in the art's known technology.
