Abstract
The utility model relates to a ceramic pressing shield die, which comprises a pressing shield die body, and is characterized in that an internal orifice circular arc is arranged in the pressing shield body; and a protecting jacket is arranged outside the pressing shield die body. The internal orifice circular arc of the ceramic pressing shield die has the advantages of reasonable design and high smooth finish, and meets the requirement that a coating is not damaged in the process of pressing a bottle cap.
Description
Technical field
The utility model relates to a kind of cover mold, relates in particular to a kind of ceramic Die for pressing cap.
Background technology
Traditional Die for pressing cap adopts the carbide alloy manufacturing; but because the hardness of material generally all surpasses only HRC70; this has just determined part using the long time will cause wearing and tearing, causes the fineness on surface to reduce greatly, makes that finally the diaphragm on bottle cap surface comes off behind the gland.Will soon get rusty in a humid environment lose the protection of surface protection film as the bottle cap of matrix by tinplate after, cause the finished product appearance damage, until influencing the competitiveness of product in market.In order to reduce bottle cap getting rusty in the gland process, be that all beer and beverage manufacturer want the problem of capturing always.
Summary of the invention
The purpose of this utility model is exactly in order to solve the above-mentioned problems in the prior art, and a kind of ceramic Die for pressing cap is provided.
The purpose of this utility model is achieved through the following technical solutions:
The pottery Die for pressing cap includes the Die for pressing cap body, and wherein: be provided with the internal orifice circular arc in the described Die for pressing cap body, described Die for pressing cap body is provided with protective sleeve outward.
Further, above-mentioned ceramic Die for pressing cap, wherein: the fineness of described internal orifice circular arc less than or equal 0.2 μ m.
The advantage of technical solutions of the utility model is mainly reflected in: the internal orifice circular arc is reasonable in design, and is highly polished, satisfies the manufacturing needs of bottle cap.Simultaneously, preferable antiwear characteristic is arranged, thermal coefficient of expansion is big.And, change internal crystal structure during fabrication, form metastable four directions mutually with cube mutually, make its four directions that has been phase-changed into twin crystal structure by single monocline with cube mutually.
Description of drawings
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solutions of the utility model, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the claimed scope of the utility model.In the middle of these accompanying drawings,
Fig. 1 is the section mould organigram that has the ceramic gland of protective sleeve;
Fig. 2 is the section mould organigram of Die for pressing cap body.
The implication of each Reference numeral is as follows among the figure:
1 Die for pressing cap body, 2 protective sleeves
3 internal orifice circular arcs
The specific embodiment
Ceramic Die for pressing cap as shown in Figure 1 and Figure 2 includes the Die for pressing cap body, and its unusual part is: be provided with internal orifice in the described Die for pressing cap body.Simultaneously, described Die for pressing cap body as major ingredient, is added with rare earth oxide as stabilizing agent with pottery in pottery, forms solid solution and complex.And, the four directions that pottery in the described internal orifice circular arc constitutes twin crystal structure with cube mutually.Further, for the ease of improving service life, this externally can be provided with protective sleeve at Die for pressing cap.Simultaneously, for the shaping perfection of bottle cap, internal orifice circular arc and Die for pressing cap body smooth transition.
Simultaneously, comprise aluminium oxide, silica, zirconia, silicon nitride for the described pottery of needs that satisfies processing.Stabilizing agent comprises CeO
2, Y
2O
3, ZrO
2And Al
2O
3And, the fineness of described internal orifice circular arc less than or equal 0.2 μ m.Certainly consider the fastening of non-accurate bottle cap, the fineness of internal orifice circular arc can also less than or equal 0.4 μ m.Same, the hardness of internal orifice circular arc is greater than or equal to HRC80.
In conjunction with the preparation method of this ceramic Die for pressing cap, its special feature is may further comprise the steps:
Step 1., powder preparation is about to alumina powder, silica, zirconia, silicon nitride and is prepared into powder, powder granularity meets ultra-fine grinding and its particle diameter is evenly distributed below 1 micron.
Step 2., the Die for pressing cap moulding includes dry-pressing formed, injection forming, extrusion modling, cold isostatic compaction, injection moulding, flow casting molding, hot-forming and hip moulding, constitutes the graininess ceramic body.
Step 3., sintering promptly adopts HIP sintering or microwave sintering method or arc plasma sintering or spreads sintering certainly, and the graininess ceramic body is densified and form solid material; Described being sintered to 1450 degrees centigrade of following sintering 1～4 hour.
Step 4., fine finishining is about to solid material that 3. step produce and adopts Al less than 1 micron
2O
3Micro mist or spark cream carry out grinding and polishing; Or adopt laser to grind and polishing; Or ultrasonic wave grinds and polishing, obtains ceramic Die for pressing cap.Like this, the contact of ceramic Die for pressing cap and bottle cap want the surface exigent fineness is arranged, as minute surface, with increase lubricity, wearability.
At last, encapsulate, the ceramic segment that is about to ceramic Die for pressing cap is connected with stainless steel or carbon steel material, adopts bonding glue or mechanical means to compress into.
Again further, participated in plasticizer and binding agent in the described powder, described plasticizer is a weight ratio 10%～30% thermoplastic plastic, and described binding agent is a weight ratio at 1%～2% polyvinyl alcohol or methylcellulose or marine alga acid amide.Simultaneously, described binding agent and plasticizer evenly mix under 150～200 ℃ of temperature with powder.And, convenient in order to make, in powder, participate in weight ratio at 1～2% lubricant, described lubricant is a stearic acid.
Simultaneously, in order to satisfy the good use of flux medium, described injection forming is to be the flux medium with water, add degumming agent and binding agent, and adding makes slip particle surface formation electric double layer make the non-setting organic additive of slip stable suspersion, exhaust after fully grinding is injected in the plaster mold then.Be added with dispersant in the described casting process, described dispersant comprises polypropylene amine, gum arabic.Specifically, the described dry-pressing formed simple and inner wall thickness of shape that only limits to surpasses 1mm, length-to-diameter is not more than 4: 1 object, dry-pressing formed used powder granule is 60～200 orders, include adopt fluid pressure type or mechanical type press with semi-automatic or full-automatic molding mode carry out single shaft to or two-way moulding, the maximum pressure of described press is 200Mpa.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing the utility model, the internal orifice circular arc is reasonable in design, and is highly polished, satisfies the manufacturing needs of bottle cap.Simultaneously, preferable antiwear characteristic is arranged, thermal coefficient of expansion is big.And, change internal crystal structure during fabrication, form metastable four directions mutually with cube mutually, make its four directions that has been phase-changed into twin crystal structure by single monocline with cube mutually.
