The reverse operation stroke crossing material fetching mechanism and pressure mechanism synthesizes the work process of feeding.
In other embodiments, two metallic objects, when heating position heating, are provided with the temperature sensing for controlling its temperature
Device, in docking position using the welding having external pressure；Additionally use left and right or clamping setting up and down, to being sandwiched in two gold
Belong to the periphery of the welding end of body, (only have adjacent during due to welding to prevent from deforming in fusion process in metallic object
End is close to molten state, now, easily deforms under external force, therefore it may only be necessary to carry out periphery to end add
Gu.Clamping, can promote Arc moulding board 70 (as schemed using equally distributed three cylinders of ring (can also be two)
Shown in 2), centering is closed up and is formed.
The invention also discloses a kind of solderless docking calculation of Huang platinum jewelry, the method is the jewelry contact that will dock
It is heated up to its fusing point, constant temperature keeps fusing point state that two jewelry contacts are linked together, and makes the process of the two welding.Various metals
The temperature of jewelry contact heating is different, and gold will be heated to 1064.43 degree about, and platinum will be heated to 1768 degree about, and k gold will
It is heated to 900 degree about (because k gold has different formula).The connected mode of the present invention can be made by heating using the said equipment
Its temperature reaches fusing point, and jewelry two tip node that will dock is closely packed together, and two ends will be welded together mutually, can adopt
With not only environmental protection but safety " hydrogen-oxygen decomposer " decompose out " hydrogen-oxygen " combustion high temperature heating.The process of heating, by " hydrogen
" oxyhydrogen " that generate is connected out by oxygen decomposer " with special trachea, connects at the gas outlet of trachea
Special resistant to elevated temperatures firelock, firelock can use the size of on-off control gas output, if it is desired to it is necessary to pressure gas during high temperature
Power accordingly adjusts increase.The process of whole heating is: open firelock air valve, igniting, and adjust the size of firepower, be aligned is to be docked
Two ends, are heated to till it is welded together.
Yellow platinum product (circular product, such as yellow platinum ancient cooking vessel) is welded using the inventive method, following step can also be adopted
Rapid:
1) first platinum semi-finished product are carried out feeding, heating in the left tool that left-hand rotation disk is provided with, then by gold semi-finished product
Carry out feeding, heating in the right tool that right-hand rotation disk is provided with；By left and right heating gun, two semi-finished product being preheated (reaches molten
The 50%-90% of jointing temp) after platinum semi-finished product and gold semi-finished product rotate to the docking position of two rotating disks；
2) it is additionally provided with a shared heating welding gun in docking position, the pressure of heating welding gun is to 1mpa, flame temperature 1000
DEG C, heating welding gun is preheated to the connection part of platinum semi-finished product and gold semi-finished product, and so that platinum semi-finished product temperature is reached
1400-1500℃；
3) and then by welding gun flame be aligned gold semi-finished product welded with platinum semi-finished product, until being formed all in commissure
Even molten bath；
4) further respectively have before and after docking position and with synchronous rotary and can be respectively used to clamp left tool, before right tool
Rotary shaft, rear rotary shaft；According to the track of gold semi-finished product and the junction surface of platinum semi-finished product, front rotary shaft, rear rotary shaft are not
The left tool of disconnected uniform rotation, right tool, the relative position at adjustment junction surface, make whole junction surface form uniform seamless welding knot
Structure.
(concrete structure may be referred to the patent literary composition of Patent Office of the People's Republic of China cn102380714a to if it is for yellow platinum ancient cooking vessel
Offer) processing in addition it is also necessary to successively gold journal stirrup and the gold legs of the tripod be alignd with platinum semi-finished product ancient cooking vessel seat again, using above-mentioned welding
Method, gold journal stirrup and the gold legs of the tripod is respectively welded at the corresponding position of platinum semi-finished product ancient cooking vessel seat, as finished product Huang platinum ancient cooking vessel
(include 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 described platinum
Gold ancient cooking vessel abdomen in the middle part of golden semi-finished product ancient cooking vessel seat, it is welded on 3 gold legs of the tripod of described platinum semi-finished product ancient cooking vessel seat bottom).Using this
The welding method of invention, makes platinum and gold ornament engage firm, good looking appearance, the method is simple to operate simultaneously, pollution-free, raw
Produce efficiency high.
In sum, the present invention adopts rotary-disk type structure, two metallic objects is attached separately on rotating disk, by the rotation of rotating disk
Turn, rotate the docking position overlapping to the two after heating, carry out welding, and the metallic object in welding is applied by pressure mechanism
It is added on specified big pressure, then taken out by material fetching mechanism.Whole fusion process be automatically performed under control of the control system so that
The production efficiency of welding is greatly improved.Operator only need to carry out feeding (two metallic objects are contained on rotating disk) and
Two kinds of shirtsleeve operations of blanking (finished product after completing welding is taken off from rotating disk) it is not necessary to the operation of complexity, thus
It is easier to ensure that the quality of product.
The above-mentioned technology contents only to be further illustrated the present invention with embodiment, are easier to understand in order to reader, but not
