It comprises zirconia ceramics watchcase, some soldering paste cross nitriding furnace, metal screw, bottom, melting welding position, stainless steel thread part and multiple spot inwall recess, in the locating hole of zirconia ceramics watchcase, be provided with a soldering paste and cross nitriding furnace, and metal screw crosses nitriding furnace with some soldering paste and bottom matches; The locating hole inwall of described zirconia ceramics watchcase is provided with multiple spot inwall recess, between multiple spot inwall recess, is provided with melting welding position, is provided with stainless steel thread part on described metal screw. The present invention is greatly cost-saving, process time, and precision and waterproof effect are better, and whole process is simply environment friendly and pollution-free.
Description
Technical field
What the present invention relates to is wrist-watch clock and watch and jewellery industry field, is specifically related to a kind of zirconia potteryThe welding process of porcelain and metalwork.
Background technology
Design and the finished product of existing zirconia ceramics wrist-watch all solve the waterproof effect less than bottom cover of watch,Need add metal inner tube could closely be connected with bottom, and existing this process program of zirconia watch structure is more generalAll over adopting, shortcoming is that comparatively complexity and cost increase a lot. Its structure is (wherein A as shown in Figure 1For steel inner bag; B is that internal screw thread is fastening).
It is not that the high rigidity characteristic of zirconia ceramics wrist-watch has determined to want machining screw on ceramic workpiecePossible, there is zirconia ceramics manufacturer to attempt first processing thread sintering again before sintering,But zirconia ceramics workpiece sintering is in high temperature sintering, problem on deformation be solve less than. AnotherKind method is to be also inadvisable by metal screw glue bonding way on zirconia ceramics part, becausePulling force is inadequate, does not have fastening effect. In sum I to take mode be to separate by fusion casting principleCertainly, how the founding of metal thread just can be efficiently solved on zirconia ceramics part to pulling force and fasteningPerplex.
Summary of the invention
For the deficiency existing in prior art, the present invention seeks to be to provide a kind of zirconia potteryThe welding process of porcelain and metalwork, greatly cost-saving, process time, precision and waterproof effect are moreGood, whole process is simply environment friendly and pollution-free.
To achieve these goals, the present invention realizes by the following technical solutions: a kind of oxygenChange the welding process of zircon ceramic and metalwork, the syndeton bag of zirconia ceramics watch case and bottomDraw together zirconia ceramics watchcase, some soldering paste cross nitriding furnace, metal screw, bottom, melting welding position and multiple spotInwall recess, described zirconia ceramics watchcase is provided with the locating hole for fixed bottom cover, describedLocating hole inwall is provided with multiple spot inwall recess, in described locating hole, inserts and is useful on connection metalThe metal thread part of screw, described metal thread part is by soldering paste and multiple spot inwall recess and locating holeInwall melting welding is integrated.
The processing step of described welding process is: it is fixed first zirconia ceramics watchcase bottom to be processedHole, position, then adopts laser mode multiple spot processing recess at locating hole inwall, forms multiple spot inwall recessedPosition; Clean machining position afterwards, then in multiple spot inwall recess filling part silver paste, then by metal spiral shellTooth part is put into locating hole and is crossed nitriding furnace by a soldering paste and carry out melting welding, make metal thread part outer wall withThe melting welding of locating hole inwall is integrated.
Described metal thread part is stainless steel thread part.
The present invention has following beneficial effect: zirconia ceramics table normally all need be at ceramic case Nei JiajinBelong to inner bag, at the bottom of metal inner tube, reprocessing thread could be connected with bottom cover of watch firm. Adopt us moltenWeldering mode zirconia ceramics table needn't be used metal inner tube again, greatly cost-saving, process time,Precision and waterproof effect are better, and whole process is simply environment friendly and pollution-free.

Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understandUnderstand, below in conjunction with detailed description of the invention, further set forth the present invention.
With reference to Fig. 2-4, this detailed description of the invention by the following technical solutions: zirconia ceramics watch caseWith the syndeton of bottom comprise zirconia ceramics watchcase 1, some soldering paste cross nitriding furnace 2, metal screw3, bottom 4, melting welding position 5 and multiple spot inwall recess 7, described zirconia ceramics watchcase 1 is provided withFor the locating hole of fixed bottom cover 4, be provided with multiple spot inwall recess 7, institute at described locating hole inwallIn the locating hole of stating, insert the metal thread part 6 that is useful on connection metal screw, described metal thread part6 are integrated with the melting welding of locating hole inwall by soldering paste and multiple spot inwall recess 7.
The processing step of described welding process is: it is fixed first zirconia ceramics watchcase bottom to be processedHole, position, then adopts laser mode multiple spot processing recess at shrinkage pool inwall, clean machining position afterwards,Again in position, hole portion filling part silver paste, then metal thread part is put into position, hole and enter nitriding furnace melting welding;Separating tensile test through melting welding screw with zirconia ceramics watchcase can pass through completely.
Between described locating hole inwall and metal thread, be provided with melting welding position 5.
Described metal thread part is stainless steel thread part.
A welding process for zirconia ceramics watchcase and metalwork, its concrete steps are:
(1), process a locating hole in the bottom of zirconia ceramics watchcase 1, adopt at location shrinkage pool inwallWith the processing of laser mode multiple spot recess, i.e. multiple spot inwall recess 7;
(2), the position of cleaning requirement processing, then cross nitriding furnace 2 in position, hole portion by a soldering paste and fill outFill part silver paste;
(3), stainless steel thread part 6 is put into position, hole and enter nitriding furnace melting welding;
(4), finally by bottom by metal screw spiral on stainless steel thread part 6 after melting welding,After screwing, metal screw separates and carries out tensile test with zirconia ceramics watchcase, and tensile test can be completeAll-pass mistake.
The zirconia ceramics table of this detailed description of the invention needn't be used metal inner tube again, greatly save intoBasis, process time, precision and waterproof effect are better, and whole process is simply environment friendly and pollution-free.The firm connected mode of this kind of zirconia ceramics part and metalwork can be widely used in wrist-watch clock and watch and headDecorations industry.
More than show and described general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand, and the present invention is not restricted to the described embodiments, above-mentioned enforcementThat in example and description, describes just illustrates principle of the present invention, is not departing from spirit of the present invention and modelUnder the prerequisite of enclosing, the present invention also has various changes and modifications, and these changes and improvements all fall into be wantedAsk in the scope of the invention of protection.
