Description
Technical field
The present invention relates to welding technology field, in particular to a kind of part welding method.
Background technology
At present, part is when welding, owing to welded stress can cause the surface around the weld part of part to produce waveform
Deformation, not only affect accessory appearance, also result in accessory size overproof or scrap.Such as two to the axle sleeve of bending
Individual side welds, or carries out welding to two parts and all can be deformed producing above-mentioned deformation, little especially for wall thickness
For the part of 1.5mm, the deformation of generation becomes apparent from, and the infringement being caused the part after welding is bigger.
Content of the invention
Effective reduce by the be deformed part welding method of welding it is desirable to provide a kind of.
To achieve these goals, the invention provides a kind of part welding method, weld in the portion to be welded of part to be welded
When connecing, making part to be welded contact with coolant, the temperature of coolant is less than the temperature when welding for the portion to be welded.
Further, coolant is contained in container, and container includes base plate and the annular sidewall being arranged on base plate, to be welded
Portion is positioned at the ullage of coolant.
Further, coolant with feature contacts to be welded before be normal temperature.
Further, coolant is water.
Further, being provided with part supporter in container, part to be welded is placed on part supporter.
Further, part supporter includes: cushion block；Part positions thing, is placed on cushion block, and part to be welded is placed on zero
On part positioning thing, part positioning thing prevents part to be welded from moving in the horizontal direction.
Further, container includes inlet and liquid outlet.
Further, portion to be welded is higher than the liquid level 5-10mm of coolant.
Further, the horizontal clearance between portion to be welded and the annular sidewall of container is 45mm to 55mm.
Further, portion to be welded is positioned at wall thickness less than or equal on the sidewall of 1.5mm.
Application technical scheme, when the portion to be welded treating soldering part welds, the produced waste heat meeting of welding
It is delivered in coolant through part to be welded, and is absorbed by coolant, and then reduce the deformation that the surface around portion to be welded produces.
Having above-mentioned analysis to understand, the part welding method of the present invention can effectively reduce by the produced deformation of welding.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
Describe the present invention below in conjunction with embodiment in detail.
When the part welding method of the present embodiment is for welding in the portion to be welded of part to be welded, make part to be welded and cooling
Liquid contacts, and the temperature of coolant is less than the temperature when welding for the portion to be welded.
The part welding method of application the present embodiment, when the portion to be welded treating soldering part welds, welding is produced
Waste heat can be delivered in coolant through part to be welded, and is absorbed by coolant, and then the surface reducing around portion to be welded produces
Deformation.Having above-mentioned analysis to understand, the part welding method of the present embodiment can effectively reduce by the produced deformation of welding.Cold
But liquid and feature contacts to be welded is more abundant, can absorb rapidly the produced waste heat of welding, reduces part further by welding
Produced deformation.
In the present embodiment, coolant is contained in container, and container includes base plate and the annular sidewall being arranged on base plate,
Before portion to be welded welds, coolant being put into container, putting in coolant by part to be welded, portion to be welded is positioned at
The ullage of coolant.Owing to the coolant in container plays the effect of heat absorption, it is possible to increase the utilization rate of coolant so that
Coolant fully absorbs heat.
In the present embodiment, it is normal temperature before coolant and feature contacts to be welded.So, there is enough endothermic effects
Simultaneously without before welding coolant being processed.
In the present embodiment, coolant is water.Water is not only convenient for drawing materials, and owing to specific heat ratio is relatively big, certain absorbing
After heat, it is slow that its temperature rises.
In the present embodiment, being provided with part supporter in container, part to be welded is placed on part supporter.By to be welded
Part is put into the step in coolant and is farther included part supporter is put into container, and coolant is put into container, part
Supporter is positioned under the liquid level of coolant, is placed on part to be welded on part supporter.Of course, it is possible to change each operation
Order, for example, coolant is put into and again part supporter is put into container after container.
In the present embodiment, part supporter includes cushion block and part positioning thing, and part positioning thing is placed on cushion block, to be welded
Part is placed on part positioning thing, and part positioning thing prevents part to be welded from moving in the horizontal direction.Part supporter is put
Enter the step in container to farther include to place in a reservoir by cushion block, then place part location division on cushion block.Owing to having
Cushion block, during because even too much coolant can be held in container, the liquid level of this coolant will not have portion to be welded yet so that
Cannot weld.When coolant flow, part to be welded rocks so that reducing welding effect.
In the present embodiment, container includes inlet and liquid outlet, when the portion to be welded treating soldering part welds, enters
While liquid mouth flows into coolant, liquid outlet flows out coolant, so ensure that the temperature substantially constant of coolant in container,
Improve endothermic effect further.Preferably, inlet and liquid outlet are respectively positioned on annular sidewall and deviate from each other setting, so
Turbulent flow or eddy current can be produced, improve the utilization rate of coolant further.
In the present embodiment, part to be welded is fixed on part positioning thing, and part positioning thing is fixed on cushion block.Connecting to neutral to be welded
Part can more stably be positioned at container.
In the present embodiment, portion to be welded is higher than the liquid level 5-10mm of coolant.Through inventor's lot of experiments, it was demonstrated that in employing
State and be sized to, while rapid cooling, not affect welding effect.
In the present embodiment, the gap between portion to be welded and the annular sidewall of container is 45mm to 55mm, preferably 50mm.
The convenient enforcement of above-mentioned size is used to weld.
In the present embodiment, portion to be welded be positioned at wall thickness less than or equal to 1.5mm sidewall on, above-mentioned sidewall welding when institute
The beneficial effect producing becomes apparent from.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification of being made, etc.
With replacement, improvement etc., should be included within the scope of the present invention.
