Abstract
The invention discloses a non-pollution cold extruding molding method and a cold extruding mould for a packaging container flange. The method is characterized in that a flange workblank with consistent flange boss thickness, which is subjected to punch forming by blanking and molding moulds, is under the effect of a male die with reverse pyramidal upper end, materials on a flange boss axially flow along the flange, wall thickness needed by turning threads is finally formed in a flange hole, and a flange finished product is obtained by subsequent corner cut, thread turning and electroplating. The non-pollution cold extruding molding method and the cold extruding mould for the packaging container flange has the advantages that the structure is simple, the manufacturing is simple, pollution does not exist, the rate of finished products is improved, and the manufacture cost is reduced.
Description
Technical field
The present invention relates to a kind of packaging-container production method and mould, especially the cold extrusion method of packing container cooperage spigot flange and mould, the specifically pollution-free cold-extrusion molding method of a kind of pail pack flange and cold extrusion die.
Background technology
At present, the manufacture of packing container cooperage spigot flange all adopts cold-extrusion technology, for the ease of cold extrusion shaped, after blanking, moulding, need the phosphatization saponification of carrying out more than half an hour to process, and then patrix carries out cold extrusion, the stream of generation vertically under the effect of the punch of the material that makes flange boss inner surface in cold extrusion die becomes, and forms required car silk inner ring.In phosphatization saponification process, environment is produced serious influence, can be floating in workshop a large amount of be saponified, and the waste liquid producing in phosphatization saponification processing procedure could discharge after need to processing, and has not only polluted environment, and extended the manufacturing cycle, increased manufacturing cost.Fig. 1 is the schematic diagram of the flange blank before not cold extrusion, Fig. 2 is the flange semi-finished product schematic diagram after cold extrusion, as can be seen from Figure 2, the material on flange boss top arrives boss root in the effect current downflow of cold extrusion die, makes the thickness of boss root reach the required thickness of car silk.Fig. 3 is the schematic diagram of existing punch, due between the squeezing action district on punch top and flange boss inwall for face contacts, so in Cold Extrusion Process, material flowability is poor, there will be the phenomenon highly not waiting, very easily form parabola shaped breach, affected product percent of pass, must be improved.
Summary of the invention
The object of the invention is to carry out phosphatization saponification to increase the mobility of material for needing in existing packing container cooperage spigot flange Cold Extrusion Process, and phosphatization saponification contaminated environment but also extended the manufacturing cycle not only, in Cold Extrusion Process, due to face contact, very easily cause the series of problems such as defect of the highly inconsistent and opening of extruding, invent a kind of by Cold Extrusion Punch is improved, make material change line extruding into by face extruding and can save phosphatization saponification process simultaneously, reduce the pollution-free cold-extrusion molding method of pail pack flange of environmental pollution, a kind of cold extrusion die matching is provided simultaneously.
One of technical scheme of the present invention is:
The pollution-free cold-extrusion molding method of a kind of packing container flange, it is characterized in that making through blanking and forming module stamping forming, the flange blank of flange boss consistency of thickness, through a upper end, be the effect of the punch of inverted cone shape, material on flange boss is flowed to producing along flange shaft, finally in flange hole, form the required wall thickness of car silk, enter follow-up corner cut, Che Si and plating and obtain flange finished product.
When cold extrusion, should on described punch, annotate cold press oil to improve the mobility of material.
The semi-cone angle of described inverted cone shape punch, between 0.1-5 degree, produces flange boss inner-wall material to flow for line contacts between described inverted cone shape punch and flange boss inwall; At the bottom of the auger of described inverted cone shape punch, be connected with the chamfering bottom of being convenient to flange blank importing of punch upper end.
Two of technical scheme of the present invention is:
The cold extrusion die that described in a kind of claim 1, cold-extrusion molding method is used, it comprises patrix 3, plug 4, die 6 and punch 7, plug 4 is arranged in patrix 3 and with dnockout rod 1 and offsets, punch 7 is arranged in die 6, the lower support of punch 7 is on punch holder 8, punch holder 8 is arranged on location-plate 10, for die 6 is separated with punch 7 to facilitate the push rod 9 of product 5 taking-ups to be arranged on location-plate 10, the upper end that it is characterized in that described punch 7 is provided with squeezing action district, the maximum gauge in squeezing action district is less than the diameter in the non-squeezing action of punch 7 district, described squeezing action district forms by being convenient to the reverse taper 13 that chamfering 12 that product 5 inserts is connected with lower end with chamfering 12, intersect the large end of reverse taper 13 and the bottom of chamfering 12.
The vertex of a cone half-angle of described reverse taper is between 0.1-5 degree.
Beneficial effect of the present invention:
The present invention has saved the serious phosphating soap metallization processes of environmental pollution, greatly improved working environment, reduced production cost, not only shortened manufacturing time, made the blank after blanking forming can directly enter cold-extrusion technology, and because material deformation is to adopt line contact squeeze, good fluidity, there will not be highly inconsistent situation, more there will not be common parabola breach, the qualification rate of product is increased substantially.
The inventive method is simple, and mould is easy to realize, and only needs to change existing cylinder compressive plane into conical compressive plane, and Mould Machining is very convenient, only need in Cold Extrusion Process, suitably add some cold-extruded oil and can guarantee good extrusion performance.
It is simple that the present invention has mould structure, easily manufactured, pollution-free, can improve yield rate, reduces the advantage of manufacturing cost.
