Abstract
The present invention relates to a method for manufacturing thin-wall deep drawing vessels, which is a method for manufacturing metal sheets into thin-wall hollow products, such as sheet iron vessels, through a punching deep-drawing process. The present invention is characterized in that tinned steel sheets are punched and drawn more than one time, hollow vessels with relative drawing height from 80% to 200% are moulded, and the vessels can be made into encapsulation cans with covers when top cover parts are connected through lock seaming. Compared with integral vessels which are manufactured through thinning deep-drawing moulding of aluminium products or lock seaming of a plurality of tin plates, etc., the vessels of the present invention has the advantages of few working processes, low manufacture cost, no gaps in bodies of vessels, beautiful appearance, etc.
Description
The invention belongs to a kind of by the punching press deep-drawing technique sheet metal make thin wall hollow products, as the method for iron sheet container etc.
Make at present the method for thin-wall metal container such as beverage can and so on, two kinds of modes generally arranged, a kind of by aluminium through the moulding of attenuate deep-drawing technique, this class container body does not have seam, anti-splendid attire thing seepage and pollutant performance are good, but cost is higher; It is whole that another kind divides the snap-in of polylith crimping to form by taggers tin, this class container cost is lower, but the connection slit is arranged on the container body, need make the seal approach in slit after the moulding, as scolding tin or be coated with fluid sealant etc., so production process is many, the container appearance owes attractive in appearance, because of the airtight quality problem splendid attire thing seepage takes place and contamination phenomenon also is common.And use general steel sheet to make the mode of container through the punching press pull and stretch, because vessel surface need be done strict antirust processing, give to make to make troubles, so this class container is more rare in daily.
The purpose of this invention is to provide a kind of different thin-walled pull and stretch manufacturing method for container, its manufacturing procedure is few, and the container cost that makes is lower, the container body does not have slit, specious.
The present invention is achieved in that the manufacture method of thin-walled pull and stretch container, it is characterized in that using taggers tin, the punching press deep-drawing technique more than once and be shaped to the hollow body of a kind of relative pull and stretch height at 80%-200%.
Such scheme only gets final product through the punching press deep-drawing technique to making container from raw material, and manufacturing procedure is few; Because adopt taggers tin lower as the prices of raw and semifnished materials, the shaping workpiece surface has good anti-rust properties, can not remake antirust processing, process equipment adopts general pressing equipment, so the cost of container is lower; Again owing to container forms through punching press drawing and forming rather than polylith joint.So the container body does not have joint gap, anti-splendid attire thing seepage and pollutant performance good, the container appearance is also more attractive in appearance.
Below in conjunction with a kind of embodiment of the present invention the present invention is done to describe more specifically.
Embodiment: with the zinc-plated sheet material of thickness at 0.25～0.28 millimeter, through continuous punching press deep-drawing technique repeatedly, can be made into a kind of relative pull and stretch height at 80%～200% hollow body, the concrete punching press number of times of this punching press deep-drawing technique, moulding fillet, selection of lubricants and the addition etc. of mould all can be with reference to the standard or the conventional numerical value of general steel plate punching press deep-drawing technique, and this container just can become a kind of cap seal tinning that has through crimping snap-in header field.For the tin layer that keeps tin plate better is not damaged in forming process, to guarantee the good rustless property of vessel surface, and in order to prevent that surface of the work from producing fold in forming process, the surface roughness of the molding surface that this punching press deep-drawing technique is used should be not more than 1.6 microns; In order to make the used mould of punching press deep-drawing technique have good and stable continuous service behaviour, the case hardness of molding surface should be not less than HRC50; In order further to improve the compression strength of container bottom, can around chamber wall, be processed with the concavo-convex lines of enhancing through rolling technology near the place, bottom.
Claims (3)
1, the manufacture method of thin-walled pull and stretch container is characterized in that using taggers tin, the punching press deep-drawing technique more than once and become the hollow body of a kind of relative pull and stretch height at 80%-200%.
2, by the described manufacture method of claim 1, it is characterized in that the surface roughness of its forming surface of mould that this punching press deep-drawing technique is used is not more than 1.6 microns.
3, by claim 1 or 2 described manufacture methods, it is characterized in that the case hardness of its molded surface of mould that this punching press deep-drawing technique is used is not more than HRC50.
