Description
Technical field
The present invention relates to metal technical field of welding equipment, and referring in particular to one kind can be applied to carry out two kinds of different metals
It is brazed the atom weldering diffusion facilities connect.
Background technique
With the high speed development of modern science and technology, social leap progress, various new and high technologies are continued to introduce new, to meet
The demand of work and life.With the raising of product technology performance, the processing technology of product parts is also increased accordingly, is such as navigated
Smart phone used in null device, people is frequently encountered two kinds of different metals and is welded to meet product and use
Requirement in journey.
Moreover to the welding that the part of some particular/special requirements carries out, as shown in Fig. 1, the inside of part 1 is equipped with cooling bath
11, and connect by outside connecting hole 12 with external cooling system, part 1 must be together square by upper two mutual buckle closures
It can be used as a cooling-part application, processed according to conventional welding method, in addition to the periphery in outside can pass through weldering
Connect completion, and internal contact surface be can not be processed, moreover since the weld seam of welding is highly prone to welding technique, work shape
The influence of the conditions such as condition, it is easy to the phenomenon that causing unstable product quality, and then acceptance rate is caused to reduce generation.
For this purpose, proposing the concept of atom weldering in the industry, that is, wish two metals mutually to fit during heating, due to
Movement is generated after atom is heated, and then penetrates into another metallic surface, to achieve the purpose that " to weld " effect.But
Similar embodiment cannot but reach actual production effect, and reason is then that " welding " process is too long, " welding " low efficiency,
It is unable to satisfy the needs of actual production at all.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art described above place, and provide a kind of vacuum atom soldering expansion
It is casually arranged with standby.
The present invention is to be achieved through the following technical solutions: vacuum atom welds diffusion facilities, single by board, vacuum pump, indentation
Member, operating unit, vacuum chamber and power supply composition, vacuum chamber are fixedly arranged on board, and part to be processed is arranged in vacuum chamber, power supply
It is arranged in the both ends of part to be processed by electrode, is laid with welding filler metal in the contact surface of part to be processed, vacuum pump connects
Enter vacuum chamber, indentation unit acts on part to be processed, and operating unit is electrically connected to a power source.
The power supply applies the pulse of certain frequency to part to be processed in process.
The vacuum pump is in process 102~10 to the vacuum degree that part to be processed provides-5Pa。
The indentation unit is in process 10~5000KG to the pressure limit that part to be processed provides.
The vacuum chamber is in process 60~3000 DEG C to the operating temperature that part to be processed provides.
The present invention realizes the engagement of various metals, is heated and activated by electric current due to using electrical pulse diffusion technique
Metal material inner molecular structure and welding filler metal inner molecular structure promote it to accelerate and diffuse to the phase bordered on it
Firm purpose is welded to reach and can reach engagement using very small amount of welding filler metal in the inside of adjacent metal.
Detailed description of the invention:
Attached drawing 1 is prior art usage state diagram；
Attached drawing 2 is main view of the present invention；
Attached drawing 3 is rear perspective view of the present invention；
Attached drawing 4 is enlarged drawing at the A of attached drawing 3.
Specific embodiment:
See that attached drawing 2~4, vacuum atom are brazed diffusion facilities, by board 1, vacuum pump 2, indentation unit 3, operating unit 4, vacuum
Room 5 and power supply 7 form, and vacuum chamber 5 is fixedly arranged on board 1, and part to be processed A, B are arranged in vacuum chamber 5, and power supply 7 passes through electricity
Pole is arranged in the both ends of part to be processed A, B, is laid with welding filler metal 6, vacuum pump in the contact surface of part to be processed A, B
2 access vacuum chambers 5, indentation unit 3 act on part to be processed A, B, and operating unit 4 is electrically connected with power supply 7.
The power supply applies the pulse of certain frequency to part to be processed in process.
The vacuum pump is in process 102~10 to the vacuum degree that part to be processed provides-5Pa。
The indentation unit is in process 10~5000KG to the pressure limit that part to be processed provides.
The vacuum chamber is in process 60~3000 DEG C to the operating temperature that part to be processed provides.
When using the present invention, part to be processed A, B for welding are put into the workbench of vacuum chamber 5, added
The contact surface of work part A, B lay welding filler metal 6, close vacuum chamber 5, are mentioned by indentation unit 3 to part to be processed A, B
For the pressure of required setting, at the same time, vacuum pump 2 provides required vacuum ring to part to be processed A, B in process
Border is powered, and power supply 7 applies the pulse of certain frequency to part to be processed in process, and operating unit 4 controls pressure and one
Determine the pulse of frequency, and the contact site of part to be processed is heated, so that activation part to be processed A, B interior molecules
Structure and welding filler metal inner molecular structure promote it to accelerate and diffuse in the adjacent part to be processed bordered on it
Firm purpose is welded to reach and can reach engagement using very small amount of welding filler metal by portion.
Due to welding filler metal interpenetrating to the contact surface of part to be processed A, B, so that the intensity of welding position, weld seam
Gap size be significantly better than the brazing quality of similar product.
