Description
Technical field
The utility model relates to a kind of trimming device, relates in particular to a kind of device that removal band steel that the continuous unit of gravity method electro-galvanizing uses is electroplated the dendrite that limit portion produces that is applied to
Background technology
At present, at the zinc-plated unit of continuous electric of the gravity method electroplating technology of each tame steel production enterprise, be provided with the device of the dendrite that limit portion produces when removing the band steel and electroplate, remove dendrite and the template of band steel is not produced and destroy.
Yet, the operator finds now in actual application, the large-scale continuous unit of gravity method electro-galvanizing is when production auto sheet thickness coating product or coating bath processing parameter when unusual, strip edge portion can produce dendrite greatly because of limit portion current density during plating, this dendrite can cause roll marks, mass defects such as foreign matter is pressed into, cause the waster that does not satisfy customer requirement to produce, and the brilliant device of the debranching of the plating tank under the prior art, though can be used for removing the dendrite of strip edge portion when electroplating, but because the brilliant device of this debranching is external imported product, there is irrational setting in original project organization, structure is unreliable, the brilliant plant failure rate of debranching height, and can not adapt to thin specification (0.3-0.5mm) fully, softwood matter is (as DDQ, the EDDQ type) the complicated Iron and Steel Production environment of band steel, exist fault to cause the failure risk of broken belt simultaneously, cause the dendrite defective not controlled, have a strong impact on electro-galvanizing unit ordinary production.
Though at present the brilliant device of external debranching is improved, as the brilliant device of existing a kind of follow-on debranching, the brilliant device of whole debranching respectively has 1 guide deflection sheave and the brilliant scraper of debranching in band steel active side and back side between conductive rollers and registration roller.Guide deflection sheave acts on strip edge portion by air cylinder driven, plays the role of positioning; Scraper can rotate around guide wheel shaft, relies on action of gravity in strip edge portion.Scraper and guide deflection sheave connect together by axle and sliding shoe, sliding shoe can slide along guide rod under cylinder action, the brilliant device of debranching not the time spent promote sliding shoe by cylinder and open guide wheel and doctor assemblies, promote sliding shoe by cylinder when the debranching crystalline substance is devoted oneself to work and make guide wheel and doctor assemblies act on strip edge portion.Wherein the reactive force of guide deflection sheave and strip edge portion is determined by the pressure of cylinder place pneumatic circuit, specifically is to be set, adjusted by the manual pressure regulating valve in the pneumatic circuit.
But, after using for some time, the operator finds again now, expansion along with the unit product specification, the galvanizing production proportion of thin specification, softwood matter constantly increases, the brilliant device of existing follow-on debranching has begun to satisfy fully the service requirements of these products, and concrete defective is as follows:
Hole and the guide wheel shaft of the guide deflection sheave of the brilliant device of existing follow-on debranching adopt running fit.Guide deflection sheave is pushed down strip edge portion under air cylinder driven, under the moving steel strip effect, and the guide wheel rotation, guide wheel endoporus and guide wheel shaft contact surface are sliding friction.Contact surface under the effect of acid solution and dendrite bits, very easy wearing and tearing.As shown in Figure 1, after the wearing and tearing, wheel position deflection causes V-type groove sidewall to reverse the band steel.Simultaneously, after the revolute pair contact surface abrasion, guide wheel to seize up, the band steel of motion grinds cut at guided wheel slot.The band steel that cut causes contacting guide wheel is subjected to force direction uncertain, causes the band steel to reverse, and causes little limit wave to produce.
In sum, though using, the brilliant device of the debranching under the prior art behind the large-scale continuous unit of gravity method electro-galvanizing, can remove dendrite, but destruction that can be serious band steel plate type, cause serious limit wave mass defect, more seriously if the limit wave is to a certain degree serious, also can cause the equipment failure of ablation galvanic anode plate, cause heavy economic losses.For fear of limit wave defective, if do not drop into the brilliant device of this debranching, then can cause mass defects such as dendrite, roll marks, foreign matter are pressed into again, also can cause serious quality cost loss.Therefore the brilliant device of modified version debranching has seriously restricted the quality product qualification rate of thin specification, softwood matter product, becomes the restriction bottleneck of producing this series products.
So press for a kind of novel removal dendrite device now, can effectively reduce the destruction of the brilliant device of debranching to band steel plate type, guarantee the effect of thin specification, softwood matter band steel debranching crystalline substance, can not produce limit wave flatness defect, avoided the brilliant effect of debranching and pole plate to ablate effectively.
