Description
Technical field
The invention belongs to metal material processing fields, and in particular to a kind of method for improving coppersmith part non-deformability.
Background technology
Copper is widely used as common metal material with its excellent conduction and heat-conductive characteristic and suitable price
In every field.But the rigidity and creep-resistant property due to copper do not protrude, and in some applications, coppersmith part can be sent out
Raw instant deformation and creep, cause workpiece to deform.It is this to deform the copper for being particularly susceptible for being happened at the shapes such as plate or strip
In workpiece, particularly in the case where supporting condition is bad, coppersmith part significantly deforms under gravity without support end, and
And as the generation of creep, deflection incrementally increase, cause coppersmith part geomery overproof, so as to influence its normal work.
Deformation is controlled by the way of strengthening supporting because the limitation of application environment is inconvenient in view of some coppersmith parts, therefore should be taken measures
To improve the non-deformability of workpiece in itself.
In Material Field, improving the non-deformability of workpiece, there are many conventional method that kind may be employed, most common bags
It includes using the better material of rigidity or using measures such as reinforcing ribs.But other materials are used instead often due to the relation of application scenario
It is not allowed to；And reinforcing rib can generally substantially change the shape of workpiece, some application scenarios can not use, and in addition also examine
Consider the material adaptation issues of reinforcing rib and workpiece.Other methods of workpiece non-deformability are improved also more or less in the presence of such
Problem.As other materials, to improve coppersmith part non-deformability, also have in face of these problems, therefore to solve
Improve the above-mentioned problem that coppersmith part non-deformability is run into, it is desirable to develop a kind of side of new coppersmith part non-deformability
Method.
The content of the invention
To solve the conventional method for improving coppersmith part non-deformability in practical applications because workpiece material does not allow to change,
The problem of workpiece configurations limitation such as should not change and can not be applicable in, the present invention provides a kind of coppersmith part non-deformabilities that improves
Method.
The method of the raising coppersmith part non-deformability comprises the following steps：
(1) according to actual needs, slot in position needed for copper workpiece surface；
(2) metal strip is built into fluting, and the metal strip for ensuring to insert meets brazing requirements；
(3) coppersmith part and metal strip are brazed using silver-base solder so that wrapped around metal strip by silver-base solder
It wraps up in and integrally welded with coppersmith part, realizes the raising of coppersmith part non-deformability.
The material of the metal strip is preferably brass or copper.
The silver-base solder is preferably ag-cu solder.
The fluting can be T-slot.
When the requirement of coppersmith part surface smoothness is high, the metal strip inserted is preferred less than copper workpiece surface, so as to take into account
The former shaped holding of brazing area and the convenience of brazing operation.
The present invention is built into metal strip in coppersmith part fluting first, is then brazed by silver-based and forms pipe in metal strip periphery
The silver-base solder firming body of shape or approximate tubulose, the metal strip and coppersmith part which puts into connect into one
Body.The actually detected rigidity for showing this silver-base solder firming body with stereoeffect is high, and creep-resistant property is good, far
Far above the rigidity and creep-resistant property of copper, become the main reason for improving coppersmith part non-deformability.In addition, the metal inserted
If item, better than copper, also can be that the raising of coppersmith part non-deformability is made centainly in terms of rigidity and creep-resistant property
Contribution.
In conclusion the present invention raising coppersmith part non-deformability method do not use such as use instead other materials,
In the case of increasing the measures such as reinforcing rib, coppersmith part problem on deformation caused by instant deformation and creep is preferably resolved, is shown
Write the non-deformability for improving coppersmith part, it is ensured that the normal work of coppersmith part, especially suitable for improving such as plate or item
The coppersmith part non-deformability of the shapes such as shape, achieves good effect in actual use.

Specific embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
Embodiment 1
The method using the present invention for improving coppersmith part non-deformability is to the plate coppersmith part of certain 20mm thickness (such as Fig. 1 institutes
Show) resistance to deformation processing is carried out, key step is as follows：
(1) according to the design feature of the plate coppersmith part, slot on its surface, grooved section size for 16 ×
16mm, fluting distribution situation are as shown in Figure 2；
(2) in the plate coppersmith part, respectively fluting is built into brass rod of the specification for 15 × 15/R2mm, and ensures brass rod
Arrangement meet brazing requirements, concrete condition is as shown in Figure 3；
(3) the plate coppersmith part and brass rod are brazed using ag-cu solder so that by silver-bearing copper pricker around brass rod
Material wraps up and, plate copper inside workpiece formation ag-cu solder firming body integrally welded with plate coppersmith part, the plate after soldering
Shape coppersmith part is as shown in figure 4, its grooved section section situation is as shown in Figure 5.
Embodiment 2
The method using the present invention for improving coppersmith part non-deformability carries out certain strip-like copper workpiece resistance to deformation processing, main
Want step as follows：
(1) according to the design feature of the strip-like copper workpiece, slot in its surface longitudinal；
(2) copper bar is built into strip-like copper workpiece fluting, and ensures that the arrangement of copper bar meets brazing requirements；
(3) the strip-like copper workpiece and copper bar are brazed using silver-base solder so that by silver-base solder institute around copper bar
It wraps up and integrally welded with strip-like copper workpiece, strip-like copper inside workpiece forms silver-base solder firming body, the strip-like copper after soldering
Workpiece as shown in fig. 6, its grooved section section situation with it is essentially identical shown in Fig. 5.
Comparative example
Two comparisons have been carried out to embodiment 1 and 2 resistance to deformation of embodiment treated plate coppersmith part and strip-like copper workpiece
Experiment, it is specific as follows：
Section 1 takes the coppersmith part for having carried out resistance to deformation processing and the copper for not carrying out resistance to deformation processing of same specification
Workpiece imposes mechanical stress, according to the deformation reference piece of coppersmith part respectively in the identical forced position of two coppersmith parts
Rigidity.The results show：No matter plate coppersmith part or strip-like copper workpiece, carry out resistance to deformation processing after its workpiece stiffness shown
It writes and is promoted, instant deformation quantity is also substantially reduced.
Section 2 tests the coppersmith part for having carried out resistance to deformation processing applied to actual working environment.In high temperature work
Make to work under environment after long period of time, with original do not carry out resistance to deformation processing coppersmith part work under identical operating mode it is identical
The deformation of time is compared.The results show：No matter plate coppersmith part or strip-like copper workpiece, carry out resistance to deformation processing after
Deflection significantly reduces caused by creep, and workpiece creep-resistant property is obviously improved.
Two experiments of summary are as can be seen that the present invention preferably resolves coppersmith part because instant deformation and creep cause
Problem on deformation, the non-deformability of coppersmith part can be significantly improved.
