The invention also discloses the automatic welding process of noble metal solderless formulation of the present invention, for by the docking of two metallic objects at high-temperature heating, the method is the work period of being carried out material loading, heating, docking and blanking by rotating disk in a rotative pattern; The rotating disk of two metallic objects overlaps in the position of docking position, by applying the external force of setting, carries out high temperature welding; Synthesized the course of work of feeding by the reverse operation stroke of material fetching mechanism and pressure mechanism after docking.
In other embodiment, two metallic objects, when adding thermal potential heating, are provided with the temperature sensor for controlling its temperature, adopt in docking position the welding having external pressure; Additionally use left and right or clamping setting up and down; to the periphery of welding end being sandwiched in two metallic objects; to prevent from deforming (owing to only having adjacent end during welding for close to molten state in fusion process at metallic object; now; easily deform under external force; therefore, only need to carry out periphery reinforcing to end.Clamping, equally distributed three cylinders of hoop (also can be two) can be adopted to promote Arc moulding board 70 (as shown in Figure 2), and centering is closed up and is formed.
The invention also discloses a kind of solderless docking calculation of yellow platinum jewellery, the method is that the jewellery contact that will dock is heated to its fusing point, and constant temperature keeps fusing point state that two jewellery contacts are linked together, and makes the process of the two welding.The temperature of various metal jewelry contact heating is different, and gold will be heated to about 1064.43 degree, and platinum will be heated to about 1768 degree, and karat gold will be heated to about 900 degree (because karat gold has different formulas).Connected mode of the present invention can adopt the said equipment to make its temperature reach fusing point by heating, jewellery two tip node that will dock abuts against together, two ends will be welded together mutually, can adopt not only environmental protection but also " the hydrogen-oxygen decomposer " of safety decomposes " hydrogen-oxygen " combustion high temperature heating out.The process of heating, by " hydrogen-oxygen decomposer ", " oxyhydrogen " that generate is connected out with special tracheae, resistant to elevated temperatures firelock special on the gas outlet place of tracheae connects, firelock can use the size of switch control rule gas output, if when needing high temperature, corresponding for the pressure of gas adjustment must be increased.The process of whole heating is: open firelock air valve, igniting, regulates the size of firepower, aims at the two ends that will dock, and is heated to till it is welded together.
Adopt the inventive method to weld yellow platinum product (circular product, such as yellow platinum ancient cooking vessel), can also following steps be adopted:
1) first platinum semi-finished product are carried out material loading, heating in the left tool that left-hand rotation dish is provided with, then gold semi-finished product are carried out material loading, heating in the right tool that right-hand rotation dish is provided with; By left and right heating gun, platinum semi-finished product after preheating (reaching the 50%-90% of fusion temp) and gold semi-finished product are carried out to two semi-finished product and rotate docking position to two rotating disks;
2) be also provided with shared one in docking position and add heating solder iron, add the pressure of heating solder iron to 1Mpa, flame temperature 1000 DEG C, will add heating solder iron and carry out preheating to platinum semi-finished product and the half-finished connection part of gold, and make platinum semi-finished product temperature reach 1400-1500 DEG C;
3) then welding gun flame is aimed at gold semi-finished product to weld with platinum semi-finished product, until form uniform molten bath in commissure;
4) being also respectively equipped with in the front and back of docking position can synchronous rotary be respectively used to clamp left tool, the front rotating shaft of right tool, rear rotating shaft; According to the track at gold semi-finished product and the half-finished junction surface of platinum, front rotating shaft, the left tool of the continuous uniform rotation of rear rotating shaft, right tool, the relative position at adjustment junction surface, makes whole junction surface form uniform seamless welding structure.
If for the processing of yellow platinum ancient cooking vessel (concrete structure can with reference to the patent document of No. CN102380714A, Patent Office of the People's Republic of China), also need successively gold journal stirrup and the gold legs of the tripod to be alignd with platinum semi-finished product ancient cooking vessel seat again, adopt above-mentioned welding method, gold journal stirrup and the gold legs of the tripod are welded on respectively the corresponding position of platinum semi-finished product ancient cooking vessel seat, be the yellow platinum ancient cooking vessel of finished product (to comprise platinum semi-finished product ancient cooking vessel seat and be welded on 2 gold journal stirrups of described platinum semi-finished product ancient cooking vessel seat upper end, be welded on the gold ancient cooking vessel abdomen in the middle part of described platinum semi-finished product ancient cooking vessel seat, be welded on 3 gold legs of the tripod of described platinum semi-finished product ancient cooking vessel seat bottom).Adopt welding method of the present invention, make platinum and gold ornament engage firm, good looking appearance, the method is simple to operate, pollution-free simultaneously, and production efficiency is high.
In sum, the present invention adopts rotary-disk type structure, two metallic objects are contained on rotating disk respectively, by the rotation of rotating disk, rotate the docking position to the two overlaps after heating, carry out welding, and put on specified large pressure by the metallic object of pressure mechanism when welding, then taken out by material fetching mechanism.Whole fusion process completes under control of the control system automatically, and the production efficiency of welding is greatly improved.Operator only needs to carry out material loading (being contained on rotating disk by two metallic objects) and blanking (finished product after welding being completed is taken off from rotating disk) two kinds of shirtsleeve operations, do not need complicated operation, thus more easily ensure the quality of product.
Above-mentionedly only further illustrate technology contents of the present invention with embodiment, so that reader is easier to understand, but does not represent embodiments of the present invention and be only limitted to this, any technology done according to the present invention extends or recreation, all by protection of the present invention.Protection scope of the present invention is as the criterion with claims.
