Description
Technical field
The present invention relates to aluminum easy open can manufacturing process field, more particularly relate to a kind of preparation method of aluminum pop can body.
Background technology
Aluminum easy open can claims seamless tin (two pieces can) again, is made up of can body and cover, adopts different aluminum alloys to make on different manufacturing lines respectively.The general usefulness of can body be the 3004 type alloy bands of thickness 0.25mm-0.29mm, stretched punching presses etc. are used to make.Because aluminium pop can has in light weight, good leak tightness, function admirable, be difficult for advantage such as fragmentation, by in large quantities as the packing of beverages such as beer, carbonated beverage, fruit juice.At present, the production quantity of China's aluminum easy open can, along with the increase of product consumptions such as beverage constantly grows at top speed, for example output in 2003 is about 7,500,000,000,8,200,000,000 in 2004, about 10,300,000,000 in 2005, annual average rate of increase 17.5%, annual average rate of increase during this period of time before 2010 can reach 12%, and the pop can output of estimating 2010 can reach 18,000,000,000; And by to 2005 the end of the year whole nation 16 family systems jar enterprises, 22 manufacturing lines, about 11,500,000,000/year of total productive capacity are arranged.Jar material thickness develops in the direction towards attenuate, from the seventies in last century the can body material 0.42mm drop to present 0.254mm (great majority are still about 0.28mm), over 30 years reduced thickness 39.5%, yes for the attenuate material for cost-cutting, the every attenuate 0.01mm of can body material, but per 1,000 jar economical with materials are taken 0.22 dollar, but this has brought difficulty to processing, and thin material creases easily, breaks in forming process; And domestic now most of manufacturing line all be from last century the eighties introduce by foreign country to the early 1990s, the equipment period of service is long and outmoded relatively, production technology and technology fall behind, the manufacturing line that has is produced wasteful, yield rate is low, cold rolling rate as the can body material should reach 88%, milling face (two big faces) from hot rolling workshop section, to begin to the present international advanced index of the integrated yield that is cold rolled to finished product be 70%, if all mill at the founding scaling loss of calculating 3% and loss and four sides, then integrated yield has only about 65%; Cause the cost height, production efficiency is low, can not satisfy the growing aluminum easy open can demand of China.
Summary of the invention
Purpose of the present invention is exactly in order to solve the deficiency of prior art, and a kind of yield rate height that provides, the manufacture method of the aluminum easy open can body that cost control is good, production efficiency is high.
The present invention adopts following technical solution to realize above-mentioned purpose:
The preparation method of this aluminum pop can body is characterized in that, it comprises the steps: (1) conveying aluminium; The aluminium coiled material of making can body is standby, use down-ender vertical aluminium coiled material upset horizontal positioned of placing, use the coiled material car that the aluminium coiled material of horizontal positioned is transported to unreeling machine, unreeling machine unreels the aluminium coiled material, and lubricated machine is lubricated to aluminium;
(2) dashing cup stretches; By cup press aluminium is washed into the shape of a cup, the machine that draws stretches the aluminium of cup-shaped and forms jar;
(3) tank body is cleaned in deburring; After stretching jar be cut into the jar of equal height, clean tank body, again by cleaning of evaporator baker dry for standby;
(4) printed decoration; The tank body that cleaning, drying is good, primary coat or color printing glazing, root edge are filmed, by the color printing baker the oven dry of filming of a jar color printing, glazing and root edge, by interior be coated with machine give jar in a spray paint, by the interior interior spray paint that is coated with baker oven dry jar;
(5) necking down flange; The jar mouth that uses the necking down curling machine to print carries out necking down and flange;
(6) detect packing; Use Optical Inspection Machine inspection jar whether perforation is arranged; Qualified back packing gets final product.
Be provided with the rim charge system in the described step 2 the aluminium waste material that cup press, trimmer produce is in process of production reclaimed briquetting; Also be provided with emulsion system, cool off with lubricated drawing the machine mould.
Have in described step 3 cleaning process by cleaning the liquid medicine heating, adopt deionized water to make washer jar and use.
Described step 6 detects in the packet assembler, and by machine for the assembly of unit load jar being collected dress is 16 layers every layer 598 jar, ties up and twines film, and every building jar is tied up and coating.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, the employed aluminium thickness of the tank body of manufacturing of the present invention can be reduced to 0.25mm, has saved big measuring tank material, has reduced cost.
2, the present invention adopts the automation instrumentation, production efficiency height, advanced technology.
3, owing to adopted the rim charge system, can effectively improve yield rate, reduce the wastage.
4, jar type specification of the present invention is 200/202/503, and promptly jar mouthful diameter/the can body diameter/jar is high is respectively: 25.4mm/54mm/131mm is to initiate domestic still the genus; Current domestic popular jar of type specification is 206/211/413 (60mm/68mm/122mm), the current domestic popular jar of type of contrast, and diameter is less and volume is little, is adapted to very much the physiological structure of Asian's build less than the occidentals, and this jar type more is subjected to domestic consumer's favor.
