Description
Technical field
The invention belongs to the nonferrous metallurgy processing technique field, relate to a kind of welding medium that in welding process, uses specifically and improve the welding method of the double-zero aluminum foil joint of welding efficiency and effect.
Background technology
It is the following aluminium foil of 0.009mm that double-zero aluminum foil refers generally to thickness, available " as thin as cicada's wings, play wind and string instruments and can break " describes, it has shading, performance such as fresh-keeping, anticorrosion, mainly as the inner lining material of industries such as cigarette, food, medicine, electronics, all be combined with each other to strengthen the intensity of packaging material during use with other packaging material such as plastics, paper etc.Require aluminium foil to have good mouldability, continuity and the clean surface of light in the use, be delivered for use with the annealing soft state usually.
In the recombination process of aluminium foil and other packaging material, in case broken belt, to cause composite base material to scrap more than the 10m at every turn, add and wear the material that band consumes again, broken belt will directly cause the scrapping of composite base material of 15m at least, and in fact, the cost of 15m composite base material is more much bigger than same length aluminium foil cost.And broken belt has also directly influenced production efficiency.Therefore, the continuity during for the deep processing of maintenance double-zero aluminum foil is enhanced productivity, and reduces production costs, and is necessary to handle well the joint problem.
Traditional operation that is rolled down to finished product from blank is: blank-＞roll thick-＞close volume-＞finish rolling (pairing is rolling)-＞cut-＞annealing-＞pack.Normally in minute cutting process, utilize ultrasonic wave that aluminium foil is welded for the broken end that in finish rolling or cutting process, occurs.The so-called aluminium foil that refers to pairing of cutting separates, and cuts into the specification that the user needs, and rejects underproof product.Common cutting machine all carries ultrasonic welding machine, all must clean pad before each welding, with a small amount of rolling base oil aluminium foil is opened up and down to be fixed on the anvil roller, and is configured technological parameter by experienced operative employee.Even faulty soldered joint or pad and aluminium foil adhesion so also can occur, make weld seam rosin joint or damaged phenomenon occur.Not only Han Jie success rate is low, and repeatedly repeats to weld and also had a strong impact on the production efficiency of cutting.Domestic and international a lot of solder technology of report also all is that methods such as welding condition are adjusted in suggestion when regularly clearing up and changing welded disc, welding.But be difficult in the practice process hold, problem fails thoroughly to solve all the time.
The joining seam of double-zero aluminum foil welding requirements welding is smooth, alignment.Weldquality is good, and faulty soldered joint can not be arranged, and breaking point could satisfy the weld strength requirement like this.What adopt the earliest is that the magnetic stripe that has magnetic is pressed against double-zero aluminum foil on the anvil roller and welds, but because pad and anvil roller adhesion, and it is not high to be welded into power, and operates and show slightly loaded down with trivial details, and it is not high to cut production efficiency.The technical staff begins test and presses aluminium foil without magnetic stripe, gather materials on the spot and smear anvil roller on a small quantity with the base oil of rolling double-zero aluminum foil, solved the aluminium foil fixation problem, but the weldquality instability after the welding, be not that a large amount of rosin joints are exactly the weld seam breakage, welding condition is difficult to hold.So just adopted following method: the bottom double-zero aluminum foil of adjacent anvil roller is smeared with an amount of rolling base oil and is fixed, and the aluminium foil on upper strata is no longer fixed with rolling base oil, still adopts magnetic stripe to be fixed on the anvil roller, so just is very easy to fixedly joining seam operation.Problem is to still have rosin joint to produce.This situation has continued that always breakthrough was not all arranged in 2,3 years, therefore has producer to begin to adopt resistant to elevated temperatures thin double-sided glue to substitute welding, and market reflection effect is pretty good, and has abandoned bonding machine.But resistant to elevated temperatures thin double-sided glue price is higher, and the someone estimates that the cost of every meter weld seam is 6～8 yuan, once at least 12 yuan of welding.Even now, a lot of producers also are ready to select the high price double faced adhesive tape.
The fixation problem of welding joining seam has solved, main problem is when welding pad and the adhesion problems of aluminium foil, and the applicant tested once that base oil is smeared pad or aluminium foil welds again, but effect is very undesirable, mainly be that the weld seam rosin joint is serious, weld strength does not reach requirement at all.
