In Vibration welding, shorten or across conventional vibration friction welding solid phase friction plasticizing and it is unstable it is incipient melting at
Type process, reduces or eliminates solid phase fraction time, be reduced or avoided from source it is broken cut generation, to reduce labor intensity, improve
Efficiency, it is ensured that product cleannes.When taillight welds, pedestal is placed on down by the lamp holder locating mould cavity for first passing through vibration friction lower die
In mould, then lampshade is placed on by the predetermined bit architecture in lower die in lower die, increases lower table and/or reduces upper table,
Make vibration friction upper mold pass through negative-pressure adsorption structure lamp housing is adsorbed in upper mold, reduces lower table and/or work on increasing
Platform makes to form certain space between lamp housing and pedestal, is moving preheating unit in place, preheating unit is made to form hot biography with lamp housing
Connection relation is led, with the preheating before being welded to lamp housing, reaching lamp housing weld part hardness reduces or softening purpose, is exiting
It after preheating unit, abuts together, Vibration on Start-up friction welding program, carries out with lampshade to lower table relative motion to lamp housing
Friction welding setting time.
Preferably, the lampshade preheating unit is arranged by heated mould frame, and heating mould bases passes through longitudinal rail pair and lifting
Guideway forms the mobile guide of both direction；It heats mould bases and liter is driven by servo motor by ball screw assembly, drive mechanism
Drop, and cylinder driving longitudinal movement is driven by longitudinal movement.To form the movement of preheating unit both direction, meet lamp housing knot
Structure shape need makes preheating unit form the heating to lamp housing appointed part, and is adapted not by cylinder and servo motor
With the mode that drive mechanism is combined, reaches quickly and accurately position purpose.
Preferably, the lampshade preheating unit preheats the lamp housing by ceramic die progress heat transfer, ceramic die connection
There is heating dish, infrared heating silk is equipped in heating dish.With high, long lifespan using infrared heating silk thermal efficiency height and ceramic hardness
Characteristic realizes efficient and long life requirement.
It is preferred that the predetermined bit architecture of lamp housing includes multiple positioning columns, positioning column is fixedly connected under the vibration friction
On mould.It is pre-positioned with accurate, convenient realization lamp housing, is provided safeguard for precise positioning of the lamp housing in upper mold.
It is generated the utility model has the beneficial effects that reduce or eliminating broken foreign matter of cutting from source, people can be effectively reduced
Work purges workload, reduces labor intensity, improves efficiency, it is ensured that product cleannes.
