Abstract
A technology for forming concave-convex shape on the surface of metallic canteen features that a bag is put in the metallic canteen and a liquid is compressed into the bag to force the canteen wall to be deformed toward the concave cavity surface of mould. Its advantages include beautiful appearance, simple shaper, high accuracy and shaping effect.
Description
The present invention relates to a kind of technology for forming concave-convex pattern on surface of metallic canteen.
Existing metal kettle, its shape and structure includes kettle wall and bottom surface, and the wall shape of kettle has taper, back taper and cylindrical, the bottom surface is the plane.The kettle of above-mentioned shape, its preparation method one: can be welding fabrication, promptly earlier metallic plate be made taper, back taper or cylindrical wall be welded on the bottom surface on this wall again.Its preparation method two: can be punch forming, be about to metallic plate and be placed in the diel, its continuous punching press be made its continuous stretching, form cavity by mould.Because young above the taper kettle, the cavity of bottom is big, and punch die can't be deviate from.If need produce concaveconvex shape at the wall of kettle, if adopt the welding fabrication mode, on planar metal plate, strike out required concaveconvex shape earlier, and then curve wall, this not only is not easy to brake forming, and the concaveconvex shape of moulding on the wall is deformed once more.For punch forming, if make the mould that pours in the cavity again to the horizontal punching press of wall direction, this mode must cause the mould structure complexity, and for the metal kettle of taper wall, because it is young, want to make punch die in cavity again to the horizontal punching press of wall direction, just difficulty more even may not made.And the concaveconvex shape of metal kettle wall also can be subjected to the restriction of mould structure and shape.If employing shaped by fluid pressure, when soon highly pressurised liquid is directly imported kettle part blank inner chamber, because the crape of kettle part blank periphery folding and burr, and the slit of mould, seal very difficultly, highly pressurised liquid is easy to leak, and sealing device structure complexity, metal kettle surface after the moulding may need cleaning, inconvenient operation with liquid.
The object of the present invention is to provide a kind of shaped by fluid pressure that utilizes, make technology for forming concave-convex pattern on surface of metallic canteen.
For realizing purpose of the present invention, described technology for forming concave-convex pattern on surface of metallic canteen is that the top layer of metal kettle is placed oneself in the midst of in the inner chamber of die of required form, have at least a burden capsule to place in the described metal kettle top layer, liquid fed in the burden capsule inner chamber it is bulged, oppress to make of the inner cavity surface distortion of metal kettle top layer to die.
The drawing of accompanying drawing is described as follows:
Fig. 1 is that metal kettle of the present invention is placed on the structural representation between die and the burden capsule.
Below in conjunction with accompanying drawing, the embodiment of technology for forming concave-convex pattern on surface of metallic canteen of the present invention is done further ocean states:
As shown in fig. 1, in technology for forming concave-convex pattern on surface of metallic canteen of the present invention, related have metal kettle 1, die 2, a burden capsule 3.Metal kettle 1 comprises side wall layer and bottom, because the bottom of most of metal kettle is a planar structure, the present invention mainly explains the side wall layer shaped by fluid pressure to metal kettle 1, so as shown in FIG., wherein has only the side wall layer of metal kettle 1.The Eight characters shape chain-dotted line on the central point line both sides shown in the figure is the tapered shape of metal kettle side wall layer before hydraulic pressure.The integrally closed structure that burden capsule 3 is made for plastic material, it can adopt the Polyurethane plastics, and certain pliability is arranged, compressible distortion, inflatable again recovery also has an amount of bloated relaxation.Be provided with a liquid mouth 4 thereon, so that liquid, wet goods for example is from wherein input.Burden capsule 3 is made the cavity shapes near die, because it has certain plasticity, is convenient to suitable distortion.When it is placed in the cavity of die, after feeding in burden capsule 3 inner chambers by liquid mouth 4 liquid, burden capsule 3 is bulged, even the shape of the appearance of burden capsule 3 and the cavity of die is not just the same, because it has certain plasticity, metal kettle 1 top layer is bulged thereupon, and force metal kettle 1 top layer, make metal kettle 1 top layer be finalized shape at die 2 inner chambers to the distortion of the inner cavity surface of die 2.Because metal kettle 1 is metal with die 2, there is the gap between the two, and also there is the gap between metal kettle 1 and the burden capsule 3, this gap is enough to make air between the two to be discharged, so, need make metal kettle 1 top layer produce which type of shape, the inner chamber of die 2 just can be designed to corresponding shape, the formed precision height.Described die 2 has two wall moulds, and when both lumped together, its inner cavity formed the shape of the required moulding of metal kettle side wall layer.Behind shaped by fluid pressure, separately the wall mould just can make metal kettle 1 top layer wherein take out, and burden capsule 3 also takes out thereupon, and is reusable.This method not only can make the side wall surface of metal water kettle produce concavo-convex shaped face, and is applicable to the moulding that metal kettle bottom surface is produced concavo-convex shaped face.Present embodiment is because the bottom surface of the metal kettle of being explained is the plane, and the bottom surface is the side wall surface lower end that is welded on kettle, so there is not the processing that illustrates the kettle bottom surface to place situation.Described die 2 has a base plate 5 at least, and base plate 5 surrounds cavity with the wall mould can hold metal kettle 1 top layer.For present embodiment, because metal kettle 1 top layer of institute's punching press requires to be shaped to the cucurbit shape, its original state is a taper, whole die 2 is made wall mould and a base plate 5 of two symmetries, make that the die manufacturing is simple, be convenient to separately, be placed on operation on the die holder 6, easy to loading and unloading, and metal kettle and burden capsule to put into operation also easy.Between the wall mould of base plate 5 and two symmetries, be provided with blank holder 7, in edge deformation retraction die 2 cavitys that prevent metal water kettle 1 top layer.Because the burden capsule is the integral sealing structure, it is placed in the chamber of die, when liquid is full of therein and have certain pressure, its outer surface almost completely contacts with the die internal face with metal kettle top layer is inboard, even have the gap between metal kettle top layer and the die, the plasticity of itself material, for the kettle, particularly family expenses kettle of making little volume, because its kettle body internal cavities is little, make its suffered pressure can the equally continuous expansion of meteorologic balloon, moulding has good anti-leakage to the hydraulic pressure punch die, no matter and the openings of sizes of kettle body, the burden capsule is all put into kettle body intracavity by after the distortion compression easily, simple in structure, easy to operate.
The present invention places the burden capsule in the metal kettle top layer owing to adopt than prior art, and liquid is passed into burden In the capsule inner chamber, metal kettle top layer is bulged, force metal kettle top layer to the inner cavity surface distortion of die. Stopped liquid Directly contact with the metal kettle, concerning the hydraulic punch mold forming, have the metal kettle of being convenient to produce various good looking appearances, Shaping jig is simple, and the precision height is easy to operate, low cost of manufacture, the advantage of good forming effect.
