Abstract
The invention discloses a battery-shell surface rust prevention method, which is characterized in that a cleaning-coating net rack with uncleaned battery shells of which ports are outwards is sequentially put into a ten-groove cleaning machine, cleaned, dewatered, soaked-coated and dried in turn; cleaning temperature is 55+/-10 DEG C; cleaning time is 8 to12 minutes; soaking-coating temperature isbetween 5 and to 35 DEG C; coating time is 8 to12 minutes; drying temperature is between 120 and 145 DEG C; and baking time is 15 to 30 minutes. The method has the advantages of overcoming the techni cal deficiencies of the prior art, increasing the rust prevention capability of metal stamping parts, simplifying process, eliminating pollution and improving production efficiency. After a steel shell is stamped and shaped, a coating method is adopted, namely to coat the outer surface of the steel shell with a layer of protective material, and the coating method not only can play a good role in preventing rust and is easy to control during production, but also can increase the yields of good products to a large extent during production. The method puts an end to environmental pollution causedby electroplating and chemical plating treatment.
Description
Technical field:
The invention belongs to the anticorrosion field, relate to a kind of antirust processing of metallic stamping pieces, especially a kind of battery-shell surface rust prevention method.
Background technology:
The battery case external form is more, is the use amount maximum with the column, and the existing lithium material of filling mostly in the shell is riveted into one with battery cap at present.
The current battery shell generally adopts the metal nickel-clad steel plate, through punching press, becomes semi-finished product.For preventing its surface oxidisation, all adopt process of surface treatment both at home and abroad.Main method has re-plating one deck nickel after the drawing of metal hull shape.Perhaps plate one deck nickel with chemical method again after the metal-back drawing.Perhaps after the drawing of nickel preplating metal-back again with the quick flash one deck of electro-plating method nickel, the perhaps quick flash one deck of chemical method nickel after the drawing of nickel preplating metal-back.
In the prior art, battery production factory owner will the employing method be first cleaning, drying, re-plating nickel, oven dry then, and this method technique controlling difficulty is big; Contaminated environment, cost is higher, and outward appearance is general.
Summary of the invention:
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of battery-shell surface rust prevention method is provided, battery case 2 ports are outwards inserted cleaning coating rack 1 (because of rack is three stainless (steel) wires, in have one side not have a net, can in net, insert battery case 2, the one side outside pointing to here, can insert the one side of battery case 2 exactly, after inserting battery case 2, this simultaneously can be built with movable stainless (steel) wire, not allow battery case 2 go out net during for cleaning); To load onto (discontented also what cleaning, efficient is low) cleaning of battery case 2 coating rack 1 first groove and second groove of putting into ten groove cleaning machines successively clean, and the built-in neutral cleaning fluid 6-10Kg of first groove and second groove, first groove and the second groove temperature all are that 55 ℃ ± 10 ℃, first groove and the second groove scavenging period all are 8-12 minute; Three-flute, the 4th groove and the 5th groove rinsing that the cleaning coating rack 1 of filling battery case 2 after first groove and second groove clean is put into ten groove cleaning machines successively, three-flute, the 4th groove and the 5th groove temperature all are that 55 ℃ ± 10 ℃, every groove scavenging period all are 8-12 minute; The 6th groove dehydration that the cleaning coating rack 1 of filling battery case 2 after the 5th groove cleans is put into ten groove cleaning machines; The 7th groove that the cleaning coating rack 1 of filling battery case 2 after the 6th groove dewaters is put into ten groove cleaning machines soaks coating, and the 7th drill traverse bubble application temperature is 5-35 ℃, applied time 8-12 minute; The 8th groove dehydration that the cleaning coating rack 1 of filling battery case 2 after the coating of the 7th groove is put into ten groove cleaning machines, the frequency conversion parameter is 30-50Hz; The cleaning coating rack 1 of filling battery case 2 after the dehydration of the 8th groove is put into the 9th groove and the oven dry of the tenth groove of ten groove cleaning machines successively, the 9th groove and the tenth groove bake out temperature are 120-145 ℃ of (about 150 ℃ of the burning-point of 150 type protective liquids, so bake out temperature can not be set too high; Simultaneously bake out temperature is low excessively, just needs the stoving time lengthening), stoving time is 15-30 minute.
Only use softened water and ultrasonic wave in described three-flute, the 4th groove and the 5th groove, ultrasonic frequency is 6-8Hz.
Immersion coating solution in described the 7th groove is 150 types.
Cleaning fluid in described first groove, second groove, three-flute, the 4th groove and the 5th groove is the DQX-2 type.
The cleaning frame rotating speed of first groove, second groove, three-flute, the 4th groove, the 5th groove, the 6th groove, the 7th groove, the 9th groove and the tenth groove is that rotating speed is 10-30 rev/min; The cleaning frame rotating speed of described the 8th groove is that rotating speed is 20-40 rev/min.
Cleaning agent: DQX-2 type; Be a kind of common neutral cleaning solution, purpose is the punching oil of surface adhesion when cleaning punching press, at present my company to clean that stamping parts mainly adopts be that Tertiary Industries is produced DQX-2 type cleaning agent.
Coating confining liquid: 150 types.150 type Main Ingredients and Appearances are vegetables water kerosene, account for 87%, also have some other organic material simultaneously, mix protective liquid, and 150 types relatively are suitable for the coating of battery case 2 by experiment.The protective liquid of other model is all undesirable as 100 types, 200 types, 300 types, can not reach production requirement.
The objective of the invention is to overcome the technological deficiency of prior art, increase the antirust ability of metallic stamping pieces, simplify technology, stop to pollute, enhance productivity.After the drawing of metal box hat, adopt a kind of coating way, be coated with the very thin protective materials of one deck, not only can finely play rust inhibition, control easily in process of production simultaneously, and can improve the yields of production process largely at outer surface.The present invention has stopped the environmental pollution that plating, chemical deposit are caused when handling.
