Description
Technical field
The present invention relates to a kind of elbow processing mold, belong to bend pipe field.
Background technology
Mould is during processing elbow, because elbow directly rides over the circular arc outer end of straight section external mold, processing stability compared with
, easily there is bias, sliding pressure phenomenon, it is difficult to ensure the precision of product, defect rate is higher in difference, the finish of product surface also compared with
Difference.
A kind of new mould for being used to process elbow with straight section is disclosed in the prior art（The patent No.
CN201620209202.1）Solve above mentioned problem.But this bend pipe mould of the prior art is in use, pipe fitting
STRESS VARIATION during bending is complicated, it sometimes appear that stress mutation shape situation, and now internal stress increases or reduced suddenly, this
When, the internal stress of mutation is transferred to the root of supporting plate so that the internal stress change of supporting plate root is violent so that supporting plate root
Portion is easily broken off when interior STRESS VARIATION is violent.
The content of the invention
The present invention goal of the invention be：For of the prior art " when bend pipe mould in use, pipe fitting is bent
STRESS VARIATION it is complicated, it sometimes appear that stress mutation shape situation, now internal stress increases or reduced suddenly, at this moment, mutation
Internal stress be transferred to the root of supporting plate so that the internal stress change of supporting plate root is violent so that supporting plate root is in planted agent
Power change it is violent when be easily broken off " the problem of there is provided a kind of elbow processing mold.
In order to solve the above technical problems, the present invention is adopted the technical scheme that, a kind of elbow processing mold, by upper mould with
Mould is constituted；Mould under circular arc of the inner side provided with semi-circular groove（2）Two straight section external molds of semi-circular groove are provided with inner side（4）Even
It is connected in and is integrally formed lower mould；Outside is provided with the straight section internal model of semi-circular groove（5）On the circular arc that semi-circular groove is provided with outside
Mould（3）Connect as one the upper mould of composition；In straight section external mold（4）Directive wheel is provided with above（7）, directive wheel（7）Pass through rotating shaft（9）And
Supporting plate（8）It is connected to straight section external mold（4）Above；The directive wheel（7）With rotating shaft（9）Between be provided with resilient supporting unit.
Optimization, above-mentioned elbow processing mold, the rotating shaft（9）On be socketed with bearing one（10）, directive wheel（7）Interior socket
There is bearing two（11）, bearing one（10）Inwall and bearing two（11）Outer wall between be provided with it is some be uniformly arranged elasticity branch
Strut（12）, elastic supporting bar（12）Two ends respectively with bearing one（10）, bearing two（11）Fixed welding.
Optimization, above-mentioned elbow processing mold, the elastic supporting bar（12）For the metallic support rod of arc.
Optimization, above-mentioned elbow processing mold, the elastic supporting bar（12）Arc opening in be provided with arc auxiliary
Bar（13）, arc auxiliary rod（13）Two ends and elastic supporting bar（12）Arc opening on the inside of fixed welding.
Optimization, above-mentioned elbow processing mold, in straight section external mold（4）Both sides are provided with strap.
Optimization, above-mentioned elbow processing mold, the straight section external mold（4）Circular arc upper end be processed into fillet.
The advantage of the invention is that the drawbacks of it can overcome prior art, reasonable in design is novel.The technology of the application
In scheme, resilient supporting unit is added, when pipe fitting is bent, the part stress of pipe fitting passes through directive wheel（7）It is transferred to elasticity
Support meanss, elastic supporting bar（12）Generation elastic deformation, absorbs stress.When the stress on pipe fitting drastically changes, pass through bullet
Property support bar（12）Elastic deformation and elasticity recovery can filter out the change of stress, prevent that STRESS VARIATION is transferred to supporting plate
（8）Root causes supporting plate（8）Fracture of root.This principle is similar to automobile shock and filters road bump, and it filters STRESS VARIATION
Effect it is preferable.Arc auxiliary rod（13）With elastic supporting bar（12）Elastic deformation and deform, share elastic supporting bar
（12）Distortional stress.The maximum of stress filtering can so be increased.
Brief description of the drawings
