Description
Technical field
Door frame production technical field is taken the present invention relates to car door, one kind is particularly belonged to and takes door frame welding procedure.
Background technology
At present, the door frame of taking of existing electric double-open stopping sliding door includes connecting plate one, connecting plate two and square tube arm, the party
Pipe arm is formed using two square tubes solderings, therefore its complex process, and cost is high, while inefficiency, and using welding, it is welded
Stomata is sewed with, it is poor to merge, therefore the intensity of square tube arm is not high, and structural behaviour is poor.In closing of the door, car door easily occurs inclined
Move, cause closing of the door not tight or close wrong door, therefore it is sealed, soundproof effect is poor.It is not closed completely, closes mistake simultaneously
, there is potential safety hazard, easily cause security incident in door.
Wherein, the change of weld metal zone tissue and performance, can cause residual stress and caused therefrom caused by welding
Stress corrosion cracking (SCC), therefore conventional direct welding can not meet and take door frame process requirements.
The content of the invention
Take door frame welding procedure it is an object of the invention to provide one kind, including blank preparation, solid point, preheating, welding and
Post weld heat treatment, adds preheating and post weld heat treatment on the basis of existing welding, and preheating is conducive to lowering medium carbon steel heat affecting
The maximum hardness in area, prevents cold crack, and the best butt-welding fitting of post weld heat treatment postwelding carries out hidden lino removal immediately, surely
Determine the shape and size of structure, reduce distortion, improve mother metal, the performance of weld zone, and preheating is placed on after solid point, Ke Yiyou
The inconvenience for avoiding each building block assembling after preheating of effect, improves welding efficiency.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：One kind takes door frame welding procedure, processing step
It is as follows：
(1) blank prepares：Each building block to taking door frame：Fishplate bar one, square tube arm and connecting plate two are cleaned；
(2) solid point：Fishplate bar one and connecting plate two are separately fixed above and below square tube arm by the way of electric welding；
(3) preheat：Door frame of taking after solid point is placed into heating furnace and preheated；
(4) weld：Door frame of taking after preheating is placed on workbench or automatic soldering device, set using manually or automatically welding
It is standby to be welded, wherein when welding, first welding two it is relative while, weld remaining two again while；
(5) post weld heat treatment：By weld finish take door frame place tempering furnace in be tempered.
It is preferred that, preheating temperature is 190~350 DEG C in described step (2), and preheating time is 15~30 minutes.
It is preferred that, described step (5) needs to preheat to tempering furnace when being tempered, and preheating temperature is 300 DEG C, Ran Hou
The door frame of taking that welding is finished is put into tempering furnace, tempering furnace is warming up into 500~600 DEG C, tempering time is 45~80 minutes.
It is preferred that, preheating temperature is 295 DEG C in described step (2), and preheating time is 28 minutes.
It is preferred that, described step (5) needs to preheat to tempering furnace when being tempered, and preheating temperature is 300 DEG C, Ran Hou
The door frame of taking that welding is finished is put into tempering furnace, tempering furnace is warming up into 570 DEG C, tempering time is 65 minutes.
Compared with the prior art, beneficial effects of the present invention are as follows：
One kind of the present invention takes door frame welding procedure, and preheating and post weld heat treatment are added on the basis of existing welding, and preheating has
Beneficial to the maximum hardness for lowering medium carbon steel heat affected area, cold crack is prevented, the best butt-welding fitting of post weld heat treatment postwelding is immediately
Hidden lino removal is carried out, the shape and size of rock-steady structure reduce distortion, improve mother metal, the performance of weld zone, and preheating
It is placed on after solid point, can effectively avoids the inconvenience that each building block is assembled after preheating, improves welding efficiency.
