Abstract
The manufacture method of thin-walled pull and stretch container is a kind of method of sheet metal being made thin wall hollow products such as iron sheet container etc. by the punching press deep-drawing technique.Feature be with taggers tin more than once the punching press pull and stretch and to be shaped to a kind of relative pull and stretch height be 80%～200% hollow body, this container just can become a kind of cap seal tinning that has through crimping snap-in header field.With become the container of modes such as integral body to compare by aluminium attenuate drawing and forming or by the snap-in of polylith tin plate crimping at present, have advantages such as manufacturing procedure is few, cost is low, the container body does not stay the slit, specious.
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, be to use metal sheets, punching press deep-drawing technique more than once and be shaped to a kind of relative pull and stretch height at 80%～200% hollow body is characterized in that this metal sheets is a taggers tin.
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; Because 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 again.
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 (4)
1, the manufacture method of thin-walled pull and stretch container is to use metal sheets, and the punching press deep-drawing technique more than once and be shaped to a kind of relative pull and stretch height at 80%～200% hollow body is characterized in that this metal sheets is a taggers tin.
2, by the described manufacture method of claim 1, it is characterized in that the surface roughness of its molded 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 less than HRC50.
4,, it is characterized in that the chamber wall of container is processed with the concavo-convex lines of enhancing on every side through rolling technology near the place, bottom by claim 1 or 2 described manufacture methods.
