Description
The present invention relates to the production method of thin jar of a kind of DI jar pull and stretch exhibition.Particularly, the present invention relates to the DI jar, the production method of cylinder of steel and aluminium pot for example, it comprises drawing and exhibition metal sheet.
The DI jar is by pull and stretch (deep-draw) metallic plate, and thin these pull and stretch product of exhibition are produced then.This DI jar comprises tank body part and the bottom that the inside seamlessly is combined as a whole.Hubbing method comprise by means of the instrument that is combined into by drift and mould and blank clamping cushion block press down the system be cut into the plate of plate-like and make it to be shaped as the band end cup.The thin operation of exhibition comprises that the sidewall of the cup that will be shaped like this elongates.
In drawing and exhibition are thin, use emulsion type lubricant always.In recent years, studying in the dark water-insoluble lubricant of use and than the little emulsion type lubricant of emulsion type lubricant oils content or the lubricant of so-called solution-type water soluble always.
With the jar degreasing oil that is shaped like this, and, form etch-proof surface,, before shipment, locate drawing and crimping (flanging) then at opening (necking part) through applying and printing with the aqueous solution that contains surfactant (cleaning solution) cleaning.Therefore, the lubricant that uses for this purpose must present good greasy property.The jar that must will with lubricator be shaped in addition, degreasing and cleaning fully.Therefore must be and discarded cleaning solution is handled fully.Particularly, if use the lubricant that to remove fully, then can reduce surfactant concentrations in the cleaning solution.Like this, can improve the disposal ability of waste water.
In these cases, studying the emulsion type lubricant that insoluble lubricant of water and the replacement of solution-type water soluble lubricant mainly are used always always.
If in pull and stretch, do not use emulsion type lubricant, then need to control to the scope that meets the requirements with being applied to the aluminium of wanting moulding or the amount of other lubricant on the steel plate.If the applied amount of this lubricant is excessive, aluminium or steel plate then skid on the plate conveying roller of it being sent into draw-off gear, thereby can not transport.In addition, if a large amount of oil is stayed on the product (cup) of such formation, then the bottom of this cup may stick on the cup pipeline, thereby will produce difficulty in the thin machine of this cup exhibition of being transported to, the productivity ratio that has therefore reduced jar.
In addition, if the applied amount of this lubricant is excessive, then this plate skids at the blank retained part during pull and stretch, thereby has reduced press power.This makes the local elongation (earing) that produces fold or cause plank in flanging part (opening).If generation fold is then inhomogeneous at flanging part thickness of slab.If thickness of slab is inhomogeneous, then produces the card machine in thicker part, thereby produce the blemish that is called leakage owing in the thin step of the exhibition of following, lack lubricity.Also cause in the necking down step of the inhomogeneities of thickness of slab in final forming step and break.In addition, the cup that produces the ears or side handles of a utensil is difficult to be transported in the flattening device, because its ears or side handles of a utensil betransported ply-yarn drill.This has just reduced the productivity ratio of jar.
Otherwise, if the applied amount of lubricant is too little, then make the drawing property variation of metallic plate, thereby cause fault, cup is broken.
Use solution-type water soluble lubricant to replace the emulsion-type lubricant that in the arm-tie step, uses in order to establish in the thin step of exhibition, thereby produce the method for the production DI jar of superior function in many aspects, then need to establish the technology that the amounts of lubrication that will be applied on unfashioned aluminium or the steel plate controls to the scope of meeting the requirements.
