Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of metal Bottle & Can manufacturing process and metal bottle, can realize namely opening namely drink to realize bottle, and resealable uses, the technical purpose that recycling degree is high.
Fig. 1 shows a kind of metal Bottle & Can method of manufacturing technology, comprising:
S11: by the antitheft ditch of neck finish roll extrusion of form metal bottle;
S12: rolled thread above described antitheft ditch;
S13: described neck finish end machine-shaping is turned up crimping, described in the crimping that turns up seal with bottleneck spiral cover and contact.
Metal bottle manufacturing process comprises shaping two piths at the bottom of the shaping and tank of neck, wherein neck shaping by internal mold and adventitia according to the machine-shaping of tank neck shaped, described external mold controls profile, and described internal mold is according to scantling, and namely machining gap is determined.
As preferably, it is 22 ° that described neck arranges neck gradient, and work in-process reaches smooth-going object.The antitheft ditch of described roll extrusion can coordinate with the antitheft contact on spiral cover, and described rolled thread carries out coordinating screwing bottleneck with the internal thread of spiral cover;
As preferably, described in along bottleneck edge outwards and form bending downwards turn up crimping, described bending is vertical with metal bottle bottle baseplane, and described folded end and described bottleneck correspondence position are closed.The described crimping that turns up can realize sealing with the cushion rubber of spiral cover inside, reaches good obturation effect.
Namely this metal bottle is opened and is namely drunk, and can realize the repetition screwing hermetic of metal bottle, the function of carrying liquid.
Fig. 2 shows a kind of metal Bottle & Can method of manufacturing technology, comprising:
S21: punching press is cup-shaped, comprising: metal plates and strips, after oil surface, stamps out cup-shaped through cup press.
By internal mold and external mold, to be processed into type be neck gradient is the neck of 22 °.
In addition, the radius value of described neck chamfering is chosen as 6.1mm, improves the ride comfort of machine-shaping.
S22: after described punching press is cup-shaped, drawn machine stretches and forms the stretching tank of base diameter 51mm.
Described bottom is shaping by bed die core rod, edge mould, nose and drift time processing.
S21-S22 is the basic step of bottle processed, and namely through overcharging shape, deburring, cleaning, root edge applies, and interior spray, necking down etc., form the bottle of neck to be processed.
It should be noted that, the shape of described bottom is interior convex, its form parameter can select convex height 10mm, oblique angle, foundation ring is 45 °, in foundation ring, convexity radius is 2mm, and the setting of this size can reach the withstand voltage requirement in bottom, also can meet tank well and stand firm on a production line, smooth and easy walking, improving production efficiency.
S23: by the antitheft ditch of neck finish roll extrusion of form metal bottle;
S24: rolled thread above described antitheft ditch;
S25: described neck finish end machine-shaping is turned up crimping, described in the crimping that turns up seal with bottleneck spiral cover and contact.
In described neck formation process, need 40 unnecessary road necking down operations, and at the antitheft ditch of neck, after screw thread and the crimping that turns up complete, clean bottle, light inspection and interior inspection supervisor complete making.
Fig. 3 a shows a kind of metal bottle, comprising:
Neck finish 1 is provided with antitheft ditch 2;
Be provided with screw thread 3 above described antitheft ditch 2, described screw thread 3 coordinates fastening with spiral cover;
Described neck finish 1 end arranges the crimping 4 that turns up, described in the crimping 4 that turns up seal with bottleneck spiral cover and contact.
As preferably, described neck neck gradient 5 is 22 °.
As preferably, bottom described metal bottle, 6 diameters are 51mm.
The antitheft ditch of described roll extrusion can coordinate with the antitheft contact on spiral cover, and described rolled thread carries out coordinating screwing bottleneck with the internal thread of spiral cover;
As preferably, as shown in Figure 3 b, described in along bottleneck edge 11 outwards and form bending 41 downwards turn up crimping 4, described bending 41 is vertical with metal bottle bottle baseplane, described folded end 42 and described bottleneck correspondence position closed.The described crimping that turns up can realize sealing with the cushion rubber of spiral cover inside, reaches good obturation effect.The radius that the described crimping that turns up outwards bends can be selected according to actual manufacture requirements.
It should be noted that, the radius value of described neck chamfering 7 is chosen as 6.1mm; The shape of described bottom is interior convex, and it is 10mm that its form parameter can select convex 8 highly, and oblique angle, foundation ring 9 is 45 °, and in foundation ring, convexity radius 10 is 2mm.
Namely this metal bottle is opened and is namely drunk, and can realize the repetition screwing hermetic of metal bottle, the function of carrying liquid.
Above-mentioned size is not limited to, and preferably explains in this manual.
In sum:
Manufacturing process in the embodiment of the present invention, metal bottle is fabricated to can spiral cover sealing container, by at the antitheft ditch of neck finish place roll extrusion, screw thread, realize spiral cover fastening and the anti-theft feature of bottle, the crimping and processing is turned up, makes this crimping that turns up seal with the cushion rubber etc. in bottleneck spiral cover and contacts, realize the spiral cover sealing function of this metal bottle.Thus achieve bottle and namely open and namely drink, and after drinking, still to seal thus recycling degree improves.Further, described bottleneck gradient is set to 22 °, and machine-shaping is more smooth-going, and at the bottom of bottle, diameter is set to 51mm, improves bottom resistance to pressure and smoothness of walking on the conveyor line.
