Abstract
The utility model discloses a jetting type dephosphorizing device for metal surface, which comprises a metal to be processed, a spray component with a plurality of spray nozzles, and a spray bracket, and further comprises a drive mechanism, wherein the spray component is movably mounted on the spray bracket; the spray nozzles jet on the surface of the metal to be processed; the drive mechanism drives the spray component to perform continuous reciprocating motion on the spray bracket. According to the device, with the drive mechanism driving the spray component to perform continuous reciprocating motion in the device, the adjacent metal surface that is covered by abnormal spray nozzles can be covered by the normal spray nozzles in unit time, so as to realize that complete covering of the metal surface through jetting, reduce the defects of the metal surface after the completion of dephosphorizing and cleaning, and to achieve the continuous, efficient and stable dephosphorizing and cleaning effect. Moreover, a small amount of jetting is adopted for realizing large-area covering, so that the jetting energy is saved and the jetting efficiency and metal surface quality is improved.
Description
Technical field
The utility model relates to the technical field that jet carries out de-scaling, cleaning to the metal surface, relates in particular to the surperficial descaling device of metal plates and strips, metal pipe bar.
Background technology
Metal is in hot rolling or heat treatment process, can form the fine and close covering that one deck is comprised of metal oxide on its surface, be commonly called as " firecoat ", the existence of this firecoat is processed the further processing of metal surface and is caused significant impact, as in follow-up phosphatization, saponification, reaming and drawing are processed, easily firecoat is pressed into metal surface, not only can cause surface quality problems, in addition, hard firecoat can scratch plug, cause mould to damage or the fracture of interior tringle, accelerated the wearing and tearing of drawbench or punch.Therefore, before the metal after hot rolling and the heat treatment is entered aftertreatment technology, all to thoroughly remove its surperficial firecoat.
Domestic existing de-scaling to the metal surface also has emerging high-pressure grinding material water jet technique of scale removal except technology such as traditional pickling, shot-peening or ball blast, the processing that strips off the skin.Because the pickling meeting produces spent acid and acid mist; Shot-peening or ball blast, the processing that strips off the skin can produce a large amount of dust, and the cleaner of a general configuration is difficult to meet the demands, and make easily steel surface produce pit and surface sclerosis, and the crackle that the steel top layer is tiny is close dead, is difficult for finding blemish; And the abrasive water-jet technique of scale removal is high because having the de-scaling rate, and environmental protection is energy-conservation, and use cost is low and receive much concern.
Wherein, for plate, band metal, often adopt one or more groups jet vertically or at a certain angle to spray in plate, band, realize plate, strip surface de-scaling, rust cleaning and cleaning; For pipe, bar metal, then often adopt pipe, bar rotation to advance, one or more groups jet vertically or at a certain angle Jet with downward flow direction is realized pipe, Surface of Rod Bar de-scaling, rust cleaning and cleaning in pipe, Surface of Rod Bar.Because metal material needs the area of de-scaling larger, when carrying out de-scaling or rust cleaning to metal, can realize in theory at one or more groups nozzle large-area fully covering.But in the actual production process, often there are one or more reasons to cause single or multiple nozzles because of wearing and tearing or obstruction cisco unity malfunction, thereby be difficult to realize the fully covering of metal surface, the final effect that affects the metal surface, often occur after de-scaling, cleaning dirty or de-scaling, the cleaning defectives such as black-tape, striped, spot being arranged, such as Fig. 4, shown in Figure 5.
The utility model content
The purpose of this utility model is to provide a kind of can not affect the metal surface jet dephosphorization apparatus that the metal surface is cleaned fully because single or multiple nozzles can't work.
The metal surface jet dephosphorization apparatus that the utility model provides, comprise pending metal and with spray assembly and the spraying rack of some nozzles, described spray assembly is movably arranged on the spraying rack, described injection stream is in pending metal surface, also comprise driving mechanism, described driving mechanism drives the spray assembly and does to move back and forth continuously at spraying rack.
Described driving mechanism comprises reducing motor and toggle, described reducing motor rotates by the crank of gear driven toggle, and an end of the connecting rod of described toggle and spray assembly is hinged and drive this spray assembly in the continuously reciprocating motion of spraying rack do.
The utility model reaches its continuous reciprocating motion in certain stroke by adopting driving mechanism to drive the spray assembly, be implemented in the unit interval, nozzle by normal operation covers the metal surface of the adjacent required covering of nozzle of failing to work, thereby realize that jet is to the fully covering of metal surface, the defective of minimizing to the metal surface de-scaling, after cleaning reaches continuous, efficient, stable de-scaling and cleaning performance.The utility model is realized large-area covering with a small amount of jet, saves simultaneously jet energy, improves jet efficient and metal surface quality.

The specific embodiment
Can find out from Fig. 1 and Fig. 2, this metal surface of the utility model jet dephosphorization apparatus, comprise pending metal 1, the spray assembly 2 with some nozzles 21, spraying rack 3 and driving mechanism 4, pending metal 1 is done with speed V moving linearly, spray assembly 2 is installed on the spraying rack 3, nozzle 21 jets are in pending metal 1 surface, each nozzle be evenly arranged and adjacent nozzle between beeline L, driving mechanism 4 drives spray assemblies 2 and does to move back and forth continuously at spraying rack 3.
It can also be seen that from Fig. 1 and Fig. 2, driving mechanism 4 comprises reducing motor 41 and toggle 42 in the utility model, wherein reducing motor 41 is by the crank rotation of gear driven toggle 42, the connecting rod of toggle 42 is hinged with an end of spray assembly 2, and this toggle 42 drives spray assembly 2 and does to move back and forth continuously at elevating mechanism 3.
As can be seen from Figure 3, spraying rack 3 of the present utility model is the elevating mechanism of De-scaling box, and spray assembly 2 and driving mechanism 4 all are installed on this elevating mechanism, and driving mechanism 4 drives spray assembly 2 and does to move back and forth continuously at elevating mechanism.
It can also be seen that from Fig. 1 metal 1 pending in the utility model comprises sheet material or band, sheet material or band along continuous straight runs moving linearly, driving mechanism 4 drive the nozzle 21 of spray assembly 2 and do to move back and forth continuously perpendicular to the direction of motion of sheet material or band.
